Your answer is D){28, 42, 56, 70, 84}
To answer this question you just have to make sure the amount he pays is a multiple of 7.If you know you times table then this should be easy
Times table of 7:
7,14,21,28,35,42,49,55,63,70,77,84.
Now you just need to find an answer choice who has these numbers.Lets check it out!
A) 11 isn't a multiple of 7
B) 56 isn't a multiple of 7
C) None of these are multiples of 7 except 7 so this is also incorrect
D) This is correct because they are all multiples of 7
Hope this makes sense.

Answer:
5 rolls
Step-by-step explanation:
The perimeter lengths are the same because it's a square. So 12 times 4 is 48. You would need a minimum of 5 rolls because each roll as a length of paper of 10 feet. So 40 feet plus 8 would round to 50. That's why it would be 5 rolls.
Answer:
The new volume is 14,850cm³
Step-by-step explanation:
Given
Volume of a rectangular prism = 550cm
Required
Value of volume when the dimensions are tripled.
The volume of a rectangular prism is calculated using the following formula.
V = lbh
<em>When Volume = 550, the formula is written as follows</em>
550 = lbh
<em>Rearrange</em>
lbh = 550
However, when each dimension is tripled.
This means that,
new length = 3 * old length
new breadth = 3 * old breadth
new height = 3 * old height
<em>Let L, B and H represent the new length, new breadth and new height respectively</em>
In other words,
L = 3l
B = 3b
H = 3h
Calculating new volume
New volume = LBH
Substitute, 3l for L, 3b for B and 3h for H;
V = 3l * 3b * 3h
V = 3 * l * 3 * b * 3 * h
V = 3 * 3 * 3 * l*b*h
V = 27 * lbh
Recall that lbh = 550
So,
V = 27 * 550
V = 14,850
Hence, the new volume is 14,850cm³
Answer:
a. 496 girls
b. 110 boys
Step-by-step explanation:
a. 3:4 ------- divide 372 by 3 and you get 124 now multiply that by 4 and you get 496
b. 2:5 -------- divide 275 by 5 and you get 55 now multiply that by 2 and you get 110
