Answer:

He is not painting the bottom or top meaning that he will paint 4 sides total,   when there is a rectangular prism there are 6 sides and 3 pairs of 2 equal sides, so since there is a wall that is 9ft x 7 ft there is two of those, and since there is a wall that is 12 ft x 7 ft there are two of those as well. meaning that (7x9)·2=126 and (12x7)·2=168 when added we get 294. meaning that he needs to paint an area of 294 ft

What is 24.9% in decimal form ?
Sati [7]

Answer: 0.249

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.

We can think of 24.9% as the ratio 24.9 to 100 or 24.9 ÷ 100.

Remember that dividing by 100 moves the decimal point two places to the left so 24.9 ÷ 100 will move the decimal point two places to the left which would give us .249 or 0.249.

Therefore, 24.9% can be written as the decimal 0.249.

URGENT: I need these problems answered and steps :/ Will give the first person BRAINLIEST and please show the steps and please p
hjlf

Answer:

1) -15/32

2) 2/15

3) -203.5

4) -3/2 = -1.5

5) 10/3 = 3 1/3

Step-by-step explanation:

For 1, you just multiply the numerators and denominators together (3 by 5, 4 by 8) and then because it is negative, add the negative sign.

For 2, you multiply again, but because there are 2 negative signs, it becomes positive.

For 3, you divide 81.4 by 0.4, you could also divide 814 by 4.

For 4, you keep change flip, so the equation would become -9/4 (-2 1/4=-9/4) and 3/2 would become 2/3. The equation would be (-9/4 * 2/3). Then, you would get -18/12 which is -3/2.

For 5, you just multiply 4/3 by 5/2 which is 20/6 and because 2 negatives, it becomes positive.

PLEASE HELP FAST :(
Ket [755]
Write the equation of the line passing through the points (-7,5) and (-5,9):
y-5= \dfrac{9-5}{-5-(-7)} (x-(-7)) \\ y-5= \dfrac{4}{2}(x+7) \\ y-5=2(x+7).
You also have another two points (-3,13) and (-1,17). Look whether coordinates of these points satisfy the line equation:

1. For (-3,13) you have
 13-5=2(-3+7) \\ \{8=8\};

2. For (-1,17) you have
 17-5=2(-1+7) \\ \{12=12\}.

Conclusion: All four points lie on the line y-5=2(x+7), so <span>the relationship shown by the data is linear.</span>

Answer: Correct choice is D.<span />

12 chocolate bars for $22 or 20 chocolate bars for $33 use unit rate to determine the better buy.
jekas [21]
12c=22
6c=11
c=1 5/6
20c=33
c= 1 13/20
5/6 is about .83
13/20 is .65
12 chocolate bars for $22 is about $1.83 each
20 chocolate bars for $33 is $1.65 each

The 20 chocolate bars for $33 dollars has a better unit rate and is a better buy.
