Answer:

Kelly earns more.

Step-by-step explanation:

Find how much Luna makes first.

24hx8days=192 hours

Then put the 192 hours into groups of 4.

192h/4h=48

Now, we take 48 x 500 to find how much Luna makes.

48x$500=$24000

Now, we have found how much Luna makes. Now, we find how much Kelly makes.

24hx10d=240h

Then put the 240 hours in groups of three.

240h/3h=80

Now, we take 80x$490

80x$490=$32900

Answer:

n=−5

Step-by-step explanation:

0.6(10n+25)=10+5n

Step 1: Simplify both sides of the equation.

0.6(10n+25)=10+5n

(0.6)(10n)+(0.6)(25)=10+5n(Distribute)

6n+15=10+5n

6n+15=5n+10

Step 2: Subtract 5n from both sides.

6n+15−5n=5n+10−5n

n+15=10

Step 3: Subtract 15 from both sides.

n+15−15=10−15

n=−5

Answer: The measure of angle 1 is 39 degrees,the measure of angle 2 is 78 degrees and the measure of angle 3 is 63 degrees.

Step-by-step explanation:

We will represent the measure of angle 1 by x because it is unknown.

It says that the measure of angle 2 is twice angle 1   so we could represent that as  2x  and the measure of angle 2  is 15 less than angle 3 and we could also represent that by  2x - 15.

Now we know they all add up to 180 so add them up and set them equal to 180 and solve for x.

x + 2x + 2x -15 = 180  

5x - 15 = 180

      +15   +15

5x = 195

x = 39  

If x is equal to 39 then the measure of angle 1 is 39 degrees and the measure of angle 2 is twice that so 2(39) = 78   which also gives us the measure of angle 2 as 78.

For angle 3 it says that it has to be 15 less than the measure of angle so  subtract 15 from  78 to find the measure of angle 3.

78 - 15 = 63   The measure angle 3 is 63 degrees. Now add the measures all together to see if they equal 180 degrees .

Check:

39 + 78 + 63 = 180

  180 = 180

Answer:

one angle : 6x=6(90/11)=540/11 (49.1 rounded to the nearest tenth)

other angle=5(90/11)=450/11 (41 degrees rounded to the nearest ones)

Step-by-step explanation:

ratio of the angles 6:5

when you draw diagonal inside a rhombus it creates four right angled triangle

one angle=90

6x+5x=90 ( the other angles is complimentary)

11x=90

x=90/11

one angle : 6x=6(90/11)=540/11 (49.1 rounded to the nearest tenth)

other angle=5(90/11)=450/11 (41 degrees rounded to the nearest ones)

Answer:

shirts are $32 each and hats are $18 each

Step-by-step explanation:

x = shirts

y = hats

2x + 5y = 154

3x + 4y = 168

use either substitution or elimination

x = $32

y = $18

The price of each shirt is $32 while the price of each hat is $18.

let

the price of each shirt  = x

the price of each hat = y

Eva's purchase will be

Nicole's purchase will be

Combine the equation to find the price of each shirt and hat.

2x + 5y = 154

3x + 4y = 168

2x = 154 - 5y

x = 77 - 5 / 2 y

3x + 4y = 168

3(77 - 5 / 2 y) + 4y = 168

231 - 15 / 2 y + 4y  = 168

168 - 231 = - 7 /2 y

- 63 = - 7 / 2 y

cross multiply

-126 = -7y

y = 18

2x + 5(18) = 154

2x + 90 = 154

2x = 154 - 90

2x = 64

x = 64 / 2

x = 32

Price of each shirt  = $32

price of each hat  = $18

Answer:

The perimeter of the rectangle is 10.5p + 10.7q - 3.8r

Step-by-step explanation:

The perimeter of the triangle is calculated by adding the values of the three sides.

In this case, the values of the individual sides are expressed algebraically.

We can still add them, however, taking into consideration like terms.

Perimenter of triangle = (4.1p+4.4q) + (6.4p-5.1r) + (1.3r+6.3q)

Perimeter = 4.1p + 6.4p + 4.4q + 6.3q -5.1r + 1.3r

Now we have grouped them, we can add the different groups separately

Perimeter = 10.5p + 10.7q - 3.8r

Therefore, the perimeter of the rectangle is 10.5p + 10.7q - 3.8r

Answer:

$122.28

Step-by-step explanation:

Give the following :

Insurance worth = $240,000

Price sold = $225

P(survival) = 0.999572

P(death) = 1 - 0.999572 = 0.000428

If she survives, insurance firm makes $225

If she dies, insurance firm pays $240,000, hence the company losses :

$(225 - 240,000) = $−239775

Expected value (E(x)) = sum of P(i) * X(i)

E(x) = (P(survival) * profit made) + (P(death) * loss incurred)

E(x) = (225 * 0.999572) + (0.000428 * −239775)

= 224.9037 - 102.6237

=$ 122.28

Answer:

$773.3587

Step-by-step explanation:

The probability that the female survives = 0.999572

therefore, probability that female dies = 1-0.999572 = 0.000428

if the female survives the insurance company makes = $225

x=$250

If the female dies the insurance company pays $240,000.

So, the amount with the company = 240000-225 = $ 2390775

Therefore Expected value = 250(0.999572)-2390775(0.000428)= $773.3587

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say your final score is x

Given that,

Your final score x is 12 points less than your friend's final score.

So,

x + 12 = 195

195 = x + 12

Step-by-step explanation:

The area of a rectangle is given by the formula:

[tex]A=\ell w[/tex]

So, we are given that the area is:

[tex]x^3-5x^2+3x-15[/tex]

And the width is:

[tex]x^2+3[/tex]

And we want to find the length. To do so, first substitute the expressions into the equation:

[tex]x^3-5x^2+3x-15=(x^2+3)\ell[/tex]

Thus, to find the length, divide by (x²+3):

[tex]\displaystyle \ell = \frac{x^3-5x^2+3x-15}{x^2+3}[/tex]

We can factor the numerator:

[tex]x^3-5x^2+3x-15[/tex]

From the first two terms, factor out a x².

From the third and fourth terms, factor out a 3:

[tex]=x^2(x-5)+3(x-5)[/tex]

Combine:

[tex]=(x^2+3)(x-5)[/tex]

Putting this back:

[tex]\displaystyle \ell = \frac{(x^2+3)(x-5)}{x^2+3}[/tex]

Answer:

Density = 5751.66 gram per litre

Step-by-step explanation:

It is given that the density of a certain material 6 pounds per pint.

The conversion from pint to liter is as follows :

1 pint = 0.473 litre

The conversion from pounds to kg is as follows :

1 pound = 453.59 kg

We need to express the density from pounds per pint to grams per liter.

1 pound per pint = 958.611 gram per litre

So,

6 pound per pint = 958.611 × 6 gram per litre

6 pound per pint  = 5751.66 gram per litre

5 represent calories from other ingredients

c= 5 1/2 grams

Step-by-step explanation:

Total calories=c grams of carbohydrates + other ingredients

Total calories in granola bite=27

The equation 4c + 5 = 27 represents the relationship between these quantities

1. 5 represent calories from other ingredients

2. Priya said that neither 8 nor 3 could be the solution to the equation

4c + 5 = 27

When the solution is 8

4(8)+5=27

32+5=27

37 =27

Solution 8 gives a higher calories than total calories

When solution is 3

4(3)+5=27

12+5=27

17=27

Solution 3 gives a lower calories than total calories

3. Solution to the equation

4c + 5 = 27

Subtract 5 from both sides

4c+5-5=27-5

4c=22

Divide both sides by 4

c=22/4

=5 2/4

=5 1/2

c= 5 1/2 grams

Step-by-step explanation:

To find the number of hours it takes to cook 3 kilograms of meat, we must fist find the rate of the ration we have:

12 : 5

= 2.4

This means that if you mulitply this by the value of the weight of meat, you'll get the amount of time it takes to cook that amount of meat.  We can do ths is find the time it takes to find the hours it takes to make 3 ilograms of meat:

x : 3

x = 3 * 2.4 = 7.2

x : 3

= 7.2 : 3

I takes 7.2 hours to cook 3 kilograms of meat.  You can use this process to find all the other hours based on the weight.

Answer:

D

Step-by-step explanation:

So we have the equation:

[tex]ax+by+c=0[/tex]

First, let's convert this to slope-intercept form.

Subtract ax from both sides:

[tex]by+c=-ax[/tex]

Subtract c from both sides:

[tex]by=-ax-c[/tex]

Divide everything by b:

[tex]y=-\frac{a}{b}x-\frac{c}{b}[/tex]

We are told that a>0, b<0, and c>0.

In other words, a is positive, b is negative, and c is positive.

The slope of the equation is -a/b.

Since a is positive and b is negative, we will have:

-(+)/(-).

The negatives will cancel out. Therefore, our slope will be positive.

Since our slope is positive, our line must be upwards sloping. Eliminate answers A and C.

Also, our y-intercept is:

-c/b.

c is positive and b is negative. Thus, similarly:

-(+)/(-).

Again, the negatives cancel. This means that the y-intercept must be positive.

Out of B and D, the graph that has a positive y-intercept is D.

  224 = 16x^2 -8x

You could rearrange and use the quadratic formula at this point, but we elect to "complete the square".

  14 = x^2 -(1/2)x

  14 +1/16 = x^2 -1/2x +(1/4)^2 . . . . . add the square of half the x-coefficient

  (x -0.25)^2 = 14.0625

  x = 0.25 ± 3.75 . . . . . . take the square root; add 0.25

Only positive values of x are useful here, so we have

  x = 4

Then the dimensions are ...

  length = 4x +3 = 4(4) +3 = 19 . . . feet

  width = 4x -5 = 16 -5 = 11 . . . feet
