Work Shown:

T = C(3 + AB)

T = 3C + ABC .... distribute

3C + ABC = T

ABC = T - 3C ... subtract 3C from both sides

(AC)*B = T - 3C

B = (T - 3C)/(AC) .... divide both sides by AC

Answer:

D. h(x) = 4(x - 5)² - 18

Step-by-step explanation:

Answer:

The other number is 4/3

Step-by-step explanation:

Let the unknown number be x

Translate the equation :

[tex] - \frac{4}{3} \times x = - \frac{16}{9} \\ - \frac{4}{3} x = - \frac{16}{9} \\ [/tex]

Cross multiply

[tex] - 4x \times 9 = 3 \times - 16 \\ - 36x = - 48[/tex]

Divide both sides by -36

[tex] \frac{ - 36x}{ - 36} = \frac{ - 48}{ - 36x} \\ x = \frac{4}{3} [/tex]

Answer:

D. m∠A=43, m∠B=55, a=20

Step-by-step explanation:

Given:

∆ABC,

m<C = 82°

AB = c = 29

AC = b = 24

Required:

m<A, m<C, and a (BC)

SOLUTION:

Find m<B using the law of sines:

[tex] \frac{sin(B)}{b} = \frac{sin(C)}{c} [/tex]

[tex] \frac{sin(B)}{24} = \frac{sin(82)}{29} [/tex]

[tex] sin(B)*29 = sin(82)*24 [/tex]

[tex] \frac{sin(B)*29}{29} = \frac{sin(82)*24}{29} [/tex]

[tex] sin(B) = \frac{sin(82)*24}{29} [/tex]

[tex] sin(B) = 0.8195 [/tex]

[tex] B = sin^{-1}(0.8195) [/tex]

[tex] B = 55.0 [/tex]

m<B = 55°

Find m<A:

m<A = 180 - (82 + 55) => sum of angles in a triangle.

= 180 - 137

m<A = 43°

Find a using the law of sines:

[tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} [/tex]

[tex] \frac{a}{sin(43)43} = \frac{24}{sin(55)} [/tex]

Cross multiply

[tex] a*sin(55) = 25*sin(43) [/tex]

[tex] a = \frac{25*sin(43)}{sin(53)} [/tex]

[tex] a = 20 [/tex] (approximated)

Answer:

Answer:

$490 is the retail price

Step-by-step explanation:

75% = [tex]\frac{3}{4}[/tex]

[tex]\frac{280}{4} = 70[/tex]

[tex]70(3)=210[/tex]

[tex]280+210=490[/tex]

The retail price will be; 490 dollar.

Markup is the amount that will be increased in the original price of the considered thing.

Markdown is the amount that will be decreased from the original price of the considered thing.

Think of "up" and "down" as increasing and decreasing prices respectively.

We are given that Haas Door Co. produces truck dock door seals. Their 9' × 10' seal costs $280 to produce.

The mark-up rate = 75% of the cost to produce.

Retail price = cost price + 75 % of cost price

Therefore,

Retail price = 280 + 75 % of 280

Retail price = 280 + 0.75 x 280

Retail price = 280 + 210

Retail price = 490

Thus, retail price is $ 490

Step-by-step explanation:

The deductions are ...

  for pension and employment insurance, (5+2.4)% of $70,000

Answer:

the answer is 516

Step-by-step explanation:

Answer:

(1) The sum of the lengths of the edges of the cube is 36.

A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3

Volume = 3*3*3 = 27

(2) The surface area of the cube is 54.

A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)

6s^2 = 54

s = 3

Volume = 3*3*3 = 27

Step-by-step explanation:

All you need to uniquely define a cube is any one measurement - length of a side/edge, area of a surface, volume etc. If you have any one of them, you can uniquely determine the others. So each statement alone is sufficient here.

To show how,

(1) The sum of the lengths of the edges of the cube is 36.

A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3

Volume = 3*3*3 = 27

(2) The surface area of the cube is 54.

A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)

6s^2 = 54

s = 3

Volume = 3*3*3 = 27

4(4)+2(6)-(-2)  

16+2(6)-(-2)

multiply 2 by 6

16+12-(-2)

multiply -1 by -2

16+12+2

add 16 and 12

28+2

Answer:

X^2 +4y-2

Step-by-step explanation:

Substraction gives the difference between two points or two positions.

We were told to substraction 4x2 - 3y + 4, from (3x2 - 7y + 6)

Then we can say

(4x2 - 3y + 4) -(3x2 - 7y + 6)

If we open the bracket we have

4x2 - 3y + 4 - 3x2 + 7y - 6

Then if we collect like terms we have

4x2 - 3x2 -3y +7y +4 -6

Then we have

X^2 +4y-2

Hence the substraction between 4x2 - 3y + 4, and (3x2 - 7y + 6)

gives us X^2 +4y-2

Answer:

[r/(w + r)]^4

Step-by-step explanation:

The numbers of the different balls are not given, but here is the solution.

Let w = number of white balls.

Let r = number of red balls.

The total number of balls is w + r.

All drawings have the same probability since there is replacement.

Each drawing has the following probability of drawing a red ball:

p(red) = r/(w + r)

Since there are 4 drawings, and they are all independent events, the overall probability is the product of the individual probabilities.

p(4 red balls in 4 drawings) = [r/(w + r)]^4

To find an actual number, replace w and r with the correct numbers and evaluate the expression.

Notice that the solutions for equation A is:

[tex]x^2=2\\x=+/- \sqrt{2}[/tex]

and [tex]\sqrt{2}[/tex] is an irrational number

The other equations have rational solutions:

Equation B:  x = 1 and x = -1 are solutions (both rational numbers)

Equation D : x = 0 is the solution. (rational number)

Answer:

p(m) = 2m² - 4m +3

p(-2) = 2(-2)² - 4(-2) + 3

= 2 × 4 - 4 × (-2) + 3

= 8 + 8 + 3

= 16 + 3

= 19

The value of p(-2) of function p(m) = 2m² - 4m +3 is 19.​

The function is defined as mathematics expression defines a relationship between one variable and another variable. When we say that a variable quantity y is a function of a variable quantity x, we indicate that y depends on x and that  value of x determines what value of  y  will be. This relationship can be expressed as follows: y = f (x)

The quadratic expression is defined as an expression containing the highest power of a variable is two.

For the function p defined by p(m) given as :

p(m) = 2m² - 4m +3,

To determine the value of p(-2).​

p(m) = 2m² - 4m +3,

Substitute the value of m = -2 in the function,

p(-2) = 2(-2)² - 4(-2) +3,

p(-2) = 2(4) + 8 +3,

p(-2) = 8 + 11

p(-2) = 19

Hence, the value of p(-2) is 19.​

Step-by-step explanation:

-3^2-3(2^3)-3^2 + 2(2^3)-3^2

Answer:

Step-by-step explanation:

Given  the following angles ∠BOC=x+3, ∠AOB=4x−7, and ∠AOC=21, the expression is true about the angles;

∠AOC = ∠BOC+∠AOB

Substituting the given values into the expression, we will have;

21 = x+3+4x-7

collect the like terms

21 = x+4x+3-7

21 = 5x-4

Add 4 to both sides

21+4 = 5x-4+4

25 = 5x

Divide both sides by 5

5x/5 = 25/5

x = 5

Hence the value of x is 5

Answer:

A. 1/8 of the semester

B. 3/20 of the semester

Step-by-step explanation:

A professor wants to divide the remaining 3/4 of the semester evenly into 6 different units. A. What fraction of the semester should be spent on each unit?

B. The professor drops one unit. What fraction of the semester should be spent on each unit?

Solution

A.

A professor wants to divide the remaining 3/4 of the semester evenly into 6 different units

Total semester=3/4

Total units=6 units

Fraction of the semester that will be spent on each units = 3/4 ÷ 6

=3/4 × 1/6

=3/24

=1/8

1/8 of the semester will be spent on each units

B. If the professor drops one unit

That is 6 units - 1 unit = 5 units

Fraction of the semester that will be spent on each units=3/4 ÷ 5

=3/4 × 1/5

=3/20

Answer:

$0.75 per candy bar

Step-by-step explanation:

For this problem, we simply need to set up a system of equations to find the value of a drink, and the value of a candy bar.

Let x represent the cost of a candy bar, and y represent the cost of a drink.

60x + 110y = 265

120x + 90y = 270

Now let's use the elimination method to solve for one of the variables:

60x + 110y = 265 --> -2 ( 60x + 110y = 265 ) --> -120x + -220y = -530

-120x + -220y = -530

120x + 90y = 270

-130y = -260

y = 2

Now plug the value of y into one of the equations to find the value for x:

60x + 110y = 265

60x + 110 (2) = 265

60x + 220 = 265

60x = 45

x = 45 / 60

x = 0.75

With this, we know that the cost of a candy bar is $0.75 and the cost of drink is $2.00.

Cheers.
