Answer:

s=150c

$7450

Step-by-step explanation:

Answer:

$7450

Step-by-step explanation:

The equation would be C=5500+150S.

You would then substitute S for 13.

150x13=1950.

1950+5500=7450

The total cost would then be 7450.

Answer: n-4(32.5) > 300;n > 430tep-by-step explanation:

Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is

Profit > $300

the profit he makes is equal to the amount he is paid - the cost of supplies. The cost of supplies is $32.50 for each room. That is

n - 32.5 and

P + 32.5 × 4

Where 4 = number of rooms

P + 130

n-4(32.5) > 300;n > 430tep-by-step explanation:

given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is

Profit > $300

Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is

n - 32.5 and

P + 32.5 × 4

Where 4 = number of rooms

P + 130

The minimum profit = 300 + 130 = $430

n-4(32.5) > 300;n > 430 430

Answer:

-2

Step-by-step explanation:

using the equation y= mix + b, where m is the slope. therefore -2 is the slope

Answer:

x=29

Step-by-step explanation:

5x+35=180

5x=145

x=29

Answer:

x=29

Step-by-step explanation:

The total angle measure here is 180 degrees. Therefore, you set an equation with the angles given for 180:

5x+35=180

Then, solve:

5x=145

x=29

Answer:

y=1.5x+2

Step-by-step explanation:

Step 1, find slope

(20-8)/(12-4)

12/8 = 1.5

slope = 1.5

Step 2, find the y-intercept

y = 1.5x+b

use point (4,8)

8 = 1.5(4)+b

8 = 6+b

-6 -6

2 = b

Step 3, put it all in slope-intercept form (y = mx+b)

y = 1.5x+2

Answer: y = 1.5x+2

Answer:

B

Step-by-step explanation:

We can rule out A and D because of the area.

The area of a cube with side length 1/4 is 1/64, times 840, is 13 1/8

The area of a cube with side length 1/2 is 1/8, times 420, is 52 1/2

Answer:

B. 55 degrees

Step-by-step explanation:

40+30+x=180

x=110

110+y=180

y=70

both sides are equal, so then there would be two equal angles.

70+55+55=180

Check:40+55+85=180

Answer:

The angle is 135°

Can you show the picture? Since all I can see is the question, there's no picture attached to it.

Answer:

Well for these problems you need to know the formula so

First off we have to square the radius thats just a fancy way of saying multiply by itself so 2.8 x 2.8 = 7.84 Now we just multiply that by pi!

so 3.14 x 7.84 = 24.6176 now sense we have to round it our final answer would be 24.6

Answer:

x = 34

Step-by-step explanation:

Angles are supplementary:

x + 7 + 4x + 3 = 180

5x + 10 = 180

5x = 170

x = 34

Step-by-step explanation:

6 bananas each price $1.5 = 6*$1.5 =$9

5 orangds each price $3 =5* $3 = $15

the total price of banana and orange are

totol price = banana price + orange price

= $9 + $15

= $24

Answer:

20

Step-by-step explanation:

Step-by-step explanation:

if y varies inversely as x^2 then 1/y=x^2

note: there needs to be a constant

so let's just say that the constant is k

so we multiply k by x^2 to equal 1/y

1/y=(x^2)k

put in the values for x and y

x=4 and y=1/4

1/(1/4)=(4^2)k

4/16=k

1/4=k

now we insert k back into the first equation that we made

1/y=(x^2)(1/4)

put in the value for y

y=1

x=?

1/1=(x^2)(1/4)

4=x^2

±[tex]\sqrt{4}[/tex]=x

2=x and -2=x

Hope that helps :)

Answer:

x = 2

Step-by-step explanation:

y ∝ [tex]\frac{1}{x^{2} }[/tex] ⇒ y = [tex]\frac{k}{x^{2} }[/tex] (where k is the constant of proportionality)

k = x²y

When x = 4 and y = [tex]\frac{1}{4}[/tex],

k = (4)² × [tex]\frac{1}{4}[/tex]

  = [tex]16 * \frac{1}{4}[/tex]

  = 4

So, y = [tex]\frac{4}{x^{2} }[/tex]

When y = 1,

[tex]1 = \frac{4}{x^{2} }[/tex]

x² = 4

√x² = ±√4

∴ x = 2 or -2

I chose a power strip for this assignment. The dimensions are (2.7in x 13.2in x 1.6cm(0.625in))

Pt A. The surface area of the box is 33.05in (added up all the sides, l2 + w2 + h2 = surface area)

Pt B. 330.5in (33.05 * 10)

Pt C. 22.28in² (= l * w * h --> 2.7in * 13.2in * 0.625in)

Pt D. Scaled down by factor of 1/10: 2.23in²

Answer:

53

Step-by-step explanation:

90-37=53.............

Answer and Step-by-step explanation:

When angles are complementary, it means that, when added together, will equal 90 degrees.

To find the missing angle, we subtract 37 from 90.

90 - 37 = 53.

The measure of the other angle is 53⁰.
