Step-by-step explanation:

Answer 2

Answer:

-1/12

Step-by-step explanation:

9/4 - 7/3

To start, we need to make the denominators the same number.  In order to do that, we need to identify the factor they have in common.

4, 8, 12

3, 6, 9, 12

Twelve is the common factor, so we will use this.  Remember, whatever you do to the bottom, you must do to the top, and vice versa.

4 * 3 = 12

/12

3 * 9 (numerator) = 27

27/12

     Now, we must figure out 7/3.

3 * 4 = 12

4 * -7 = -28

-28/12

Now, take the new fractions and subtract them.

27/12 - 28/12

-1/12

What would be the estimated loss in income from operations if the solvent production were temporarily suspended for May? If a loss is incurred, enter that amount as a negative number using a minus sign

Answers

The sales are expected to drop by 20%, this represents a total estimated loss in income from operations of $213,200.

Assuming that the creation of dissolvable was to be briefly suspended for May, the estimated loss in pay from activities is not set in stone by taking a gander at the expenses related to delivering 4,000 units in April and the extended deals for May.

In April, the creation costs per unit were $45 for direct materials, $20 for direct work, $16 for variable assembling costs, and $15 for variable selling and managerial costs. There were additionally fixed expenses of $100,000 for assembling and $42,000 for selling and authoritative costs.

For May, as deals are supposed to drop by 20%, the complete expense of creation for 4,000 units in April can be duplicated by 80% to decide the comparing creation costs for May.

Similar turns out as expected for fixed costs. In this way, the complete expense of creation in May would be,

$71,200 ($45 × 4,000 × 0.8) for direct materials, $32,000 ($20 × 4,000 × 0.8) for direct work, $25,600 ($16 × 4,000 × 0.8) for variable assembling costs, and $24,000 ($15 × 4,000 × 0.8) for variable selling and authoritative costs.

The proper expenses would continue as before at $100,000 for assembling and $42,000 for selling and regulatory costs.

Accordingly, the assessed estimated loss from tasks can be determined by taking away the complete expense of creation and fixed costs for May from the normal deals income for the month.

Considering that the deals are supposed to drop by 20%, this addresses an all-out assessed misfortune in pay from tasks of $213,200 ($357,200 - $144,000).

The question is -

The production costs and selling and administrative expenses, based on the production of 4,000 units in April, are as follows:

Direct materials $45 per unit

Direct labor 20 per unit

Variable manufacturing cost 16 per unit

Variable selling and administrative expenses 15 per unit

Fixed manufacturing cost $100,000 for April

Fixed selling and administrative expenses 42,000 for April

Sales for May are expected to drop about 20% below those of the preceding month. No significant changes are anticipated in the fixed costs or variable costs per unit. No extra costs will be incurred in discontinuing operations in the portion of the plant associated with solvent. The inventory of solvent at the beginning and end of May is expected to be inconsequential.

how to simply 5x +13-5+7x

Answers

Answer: To simplify the expression 5x +13-5+7x, we need to perform the following steps:

Combine the coefficients of like terms:

-5x + 7x = 2x

5 + 13 = 18

Replace the combined terms:

2x + 18

So, the simplified expression is 2x + 18.

Answer: x = -2/3

Solution: First rearrange and combine like terms to simplify the expression.

5x + 13 - 5 + 7x
5x + 7x + 13 - 5
12x + 8 = 0

Start solving to get x by itself

12x + 8 = 0
-8 -8
12x = -8

Divide both sides by 12 to get x by itself

x = -8/12

-8/12 can be simplified to -2/3 as both 8 and 12 can be divided by 4

x = -2/3

a 6-foot person standing 29 from a street light casts an 8-foot shadow. what is the height of the street light?

Answers

The height of the street light can be calculated by using the ratio of the person's height to their shadow length. The street light is 17 feet tall.

The  height of the street light can be calculated by using the ratio of the person's height to their shadow length. In this case, the person is 6 feet tall and their shadow is 8 feet long. This gives us a ratio of 6:8 or 3:4. Since we know the person is standing 29 feet away from the street light, we can use this ratio to calculate the height of the street light. Using the ratio, we can say that for every 4 feet the person is away from the street light, the light is 3 feet tall. So if the person is 29 feet away from the street light, the light must be 3 x 29 ÷ 4 = 21.75 feet tall. However, since the height of the street light must be a whole number, we can round up and say that the street light is 17 feet tall.

a parking row has 8 spaces. four cars are pulled in randomly to park in the parking row. what is the probability that they are parked in two pairs one next to the other but at least one space exists between the two pairs? assume all four cars are different.

Answers

The probability that they are parked in two pairs one next to the other but at least one space exists between the two pairs is 1/7.

In the given question a parking row has 8 spaces.and four cars are pulled in randomly to park in the parking row.

We have to find the probability that they are parked in two pairs one next to the other but at least one space exists between the two pairs.

Number of ways to arrange 4 cars in 8 places = P(8,4)

Number of ways to arrange 4 cars in 8 places = 1680

Number of ways to arrange 4 cars in 2 pairs = N

(Choose 2 pairs of consecutive place from 8 and arrange 4 cars) = 15*4!

= 360

Number of ways to arrange 4 cars in 2 pairs so that there is no space between 2 pairs

= 5*4!

= 120

therefore,

Number of ways no two pairs are consecutive = 360-120

Number of ways no two pairs are consecutive = 240

probability=240/1680

Probability = 1/7

Therefore, the probability that they are parked in two pairs one next to the other but at least one space exists between the two pairs is 1/7.

Answers

Answer:

Proof below

Step-by-step explanation:

Area of the cross = Area of the rectangle - Area of unshaded regionEach of the unshaded regions is the same size since the arms of the cross are x ie the four unshaded rectangles are congruentTherefore to find the total area of the unshaded , first find the area of each of the unshaded rectangles and then multiply by 4

Looking at the two unshaded rectangles on the top left and bottom left, the total width of both = 2 - x.
Therefore width of one unshaded rectangle = (2-x)/2

Similarly looking at the top left and top right unshaded rectangles,  the width of two = (3-x) and therefore the length of one unshaded rectangle = (3-x)/2

Area of each unshaded rectangle = (2-x)/2 x (3 - x)/2
= (2-x)(3-x)/4Area of 4 unshaded rectangles = (2-x)(3-x)/4 x 4 = (2 -x)(3-x)(2 -x)(3-x) = 6 - 5x + x² calculated by the FOIL methodArea of the entire flag = 3 x 2 = 6 Area of the cross
= 6 - (6 - 5x + x²)
= 6 - 6 + 5x - x²
= 0 + 5x - x²
= 5x - x²

The area of the cross in the flag is equal to A = 5 · x - x².

How to determine the area of the cross in the flag

In this problem we must determine the area of the cross in a flag, this can be seen as a sum of areas of rectangles, whose formula is:

A = w · l

Where:

w - Width, in metersl - Length, in meters

Now we proceed to determine the area of the cross by following expression:

A = 3 · x + 2 · (1 - 0.5 · x) · x

A = 3 · x + 2 · x - x²

A = 5 · x - x²

Consider the function h(t) = -16t² + 32t + 128

Substitute h(t) =  0 in above equation.

-16t² + 32t + 128 = 0

We solve above quadraic equation for t.

using the Quadratic Formula where

a = -16, b = 32, and c = 128

What is significance level?

"Significance" in statistics refers to something that is "not by chance" or "likely true." We can infer that when a statistician claims that a finding is "very significant," he or she is implying that it may very well be true. It does not imply that the finding is very significant, but it does imply that it is highly likely. The fixed likelihood of incorrectly eliminating the null hypothesis when it is, in fact, true is what is referred to as the level of significance. The probability of type I error is defined as the degree of significance, and the researcher sets it based on the results of the error. The statistical significance is measured by its level of significance. It specifies whether the null hypothesis is thought to be accepted or rejected.

At a 0.05 level of significance, it can be concluded that the proportion of the population in favor of candidate A is:-

not significantly greater than 75%

The equation "tan(⍉)• cos(⍉)=sin(⍉)" is true for all values of ⍉.

The equation "(1 - cos ⍉)(1 - cos ⍉) = sin (⍉)" is true for all values of ⍉.

The equation "(1 + sin ⍉)(1 - sin ⍉) = cos ² (⍉)" is true for all values of ⍉.

How did we get the assertions?

To prove the equation "tan(⍉)• cos(⍉)=sin(⍉)", we can use the identity:

tan(⍉) = sin(⍉) / cos(⍉)

Therefore, tan(⍉)• cos(⍉) = (sin(⍉) / cos(⍉)) * cos(⍉) = sin(⍉).

To prove the equation "(1 - cos ⍉)(1 - cos ⍉) = sin (⍉)", we can use the identity:

cos²(⍉) = 1 - sin²(⍉)

So, (1 - cos ⍉) = √(1 - cos²(⍉)) = sin(⍉), and

(1 - cos ⍉)(1 - cos ⍉) = sin²(⍉) = sin (⍉).

To prove the equation "(1 + sin ⍉)(1 - sin ⍉) = cos ² (⍉)", we can use the identity:

cos²(⍉) = (1 + cos(⍉)) / 2

and

sin²(⍉) = (1 - cos(⍉)) / 2

Therefore, (1 + sin ⍉)(1 - sin ⍉) = (1 + (1 - cos(⍉)) / 2) * (1 - (1 - cos(⍉)) / 2) = (1 + (1 - cos(⍉)) / 2) * (1 + cos(⍉) / 2) = (2 + cos(⍉)) / 2 = cos²(⍉).

height of a cuboid is three-fourths of its length,breadth is 4 cm and total surface area is 608,finds the length and height of the cuboid.

Answers

Height of a cuboid is three-fourths of its length,breadth is 4 cm and total surface area is 608.

the length of the cuboid is 24 cm and its height is 18 cm.

Let us denote the length of the cuboid as "l" and the height of the cuboid as "h".

Based on the facts provided, we may conclude:

h = (3/4)l

Furthermore, the total surface area is 608, which may be computed as follows:

608 = 2(lb + bh + lh)

Extending the formula and changing the value of h:

608 = 2(lb + bh + l(3/4)l)

2(lb + 4h + (3/4)l^2) = 608

Now that we have the equation, we can solve for l by substituting the values of b (breadth) and h (height):

2(4l + 4h + (3/4)l^2) = 608

8l + 8h + (3/2)l^2 = 304

(3/2)l^2 + 8l + 8h = 304

We can now solve for l using the quadratic formula:

l = (-8 ± √(8^2 - 4 * (3/2) * (304 - 8h))) / (2 * (3/2))

Because h = (3/4)l, we may simplify by substituting this formula for h:

l = (-8 ± √(8^2 - 4 * (3/2) * (304 - 3l))) / (2 * (3/2))

Expanding the square root:

l = (-8 ± √(64 + 12l)) / 3

When we solve for l, we get:

l = 24

Finally, for h, substitute the value of l into the equation:

h = (3/4) * 24 = 18

Now, this pattern of transformation occurs when;

There is a 90° clockwise rotation. However, the other rotation that can be used to achieve this is a 270° counterclockwise rotation

Answer: Triangle XYZ can be rotated 90° counterclockwise using the origin as the center of rotation to create triangle X’Y’Z’. To obtain the original triangle XYZ, we need to rotate the triangle X'Y'Z' by 90° clockwise using the origin as the center of rotation. This means that rotating the triangle X'Y'Z' by 90° clockwise is the same as rotating triangle XYZ by 90° counterclockwise, so the answer is 90° clockwise.

suppose you want to find how many ways we can select five door prizes from seven different ones and distribute them among five people. would you use a combination or a permutation?

Answers

There are [tex]5^{7}[/tex] total ways to divide the seven different prizes because each prize is selected from among five students and is awarded to only one.

These total methods also take into account the situations in which one student, two students, three students, or four students do not receive any awards ( not five as it is compulsory to distribute all the prizes ).

We will add the "2 students left out" cases after reducing the "1 student left out" cases, but this will also add the "2 students left out" cases after adding the "3 students left out" cases, so we will reduce them once more before reducing the "4 students left out" cases.

Hence total ways :

student left out”+“2

students left out”−“3

students left out”+“4

students left out”

#SPJ4

Do the ratios 7 4 and 42 24 form a proportion?

Answers

Answer:

yes

Step-by-step explanation:

a ratio is a special form of a fraction, but it is a fraction.

so, all calculation, comparison and transformation rules of fractions apply.

7:4 = 7/4

42:24 = 42/24

and because

7/4 × 6/6 = 42/24

they are both describing the same ratio and form therefore a proportion.

a proportion simply means that two fractions are equal.

Yes because 42 divided by 7 is 6 and 24 divided by 4 is 6 which makes the ratio 7:4 and 42:24 equal to each other

A curve is such that [tex]\frac{dy}{dx}[/tex] = 2(kx-1)^5 where k is a constant.
Given that the curve passes through points ( 0 , 1) , ( 1 , 8 ) find the equation of the curve.

Answers

The equation of the curve that passes through points (0,1), (1,8) is y = 1/9 (3x - 1)⁶ + 8/9

multiply dx on both sides, To shift it over. By doing this, we get

dy = 2 (kx - 1)⁵dx

Using integration, Integrate both sides in relation to dy and dx terms next.

dy = 2 (kx - 1)⁵dx

∫ dy = ∫ 2 (kx - 1)⁵dx

y = 2 ∫  (kx - 1)⁵dx

Here, a u-substitution is possible. Suppose u = kx-1, which results in du/dx = k, which becomes du = kdx and rearranges to dx = du/k. Consequently, the subsequent steps can look like, y = 2 ∫  (kx - 1)⁵dx

y = 2 ∫ u⁵ × du/k

y = 2/k ∫ u⁵ × du

y = 2/k ( 1/ 5 +1  u⁵⁺¹ + C )

y = 2/k ( 1/ 6 u⁶+ C )

y = 2/k ( 1/ 6 (kx - 1)⁶ + C )

Let's enter (x,y) = (0,1) and use a little algebra to find C. On the right, we'll see an equation in terms of k.

y = 2/k ( 1/ 6 (kx - 1)⁶ + C )

1 = 2/k ( 1/ 6 (k × 0 - 1)⁶ + C )

1 = 2/k ( 1/ 6 + C )

k = 2 ( 1/ 6 + C )

k = 1/3 + 2C

3k = 1 + 6C

6C = 3k - 1

C = (3k - 1) / 6

Let's now insert that C value along with (x,y) = (1,8). After that, calculate k to obtain a precise number.

y = 2/k ( 1/ 6 (kx - 1)⁶ + C )

8 = 2/k  ( 1/ 6 (k × 1 - 1)⁶ + ( 3k - 1 )/6 )

Find the root of the function using a graphing calculator. The x intercept is 3 and k is the input x. This would get you,  C = (3k - 1) / 6

C = (3 × 3 - 1) / 6

C = 8/6

C = 4/3

Therefore, y = 2/k ( 1/ 6 (kx - 1)⁶ + C )

y = 2/3 ( 1/ 6 (3x - 1)⁶ + 4/3 )

y = 1/9 (3x - 1) ⁶ + 8/9 , hence the final equation.
