Sphinxa [80]

Answer:

Shop A & $400

Step-by-step explanation:

-4.7 + 27.5 + 122.3 = $145.1 (Shop A)

-0. 2 + 14.5 + 130.4 = $144.7 (Shop B)

Difference = 145.1 - 144.7 = $0.4

0.4 × 1000 = $400

Given:

The coin wrapper volume = 27,480 mm³.

The coin diameter = 21.18 mm.

There are 50 such coins.

To find:

The thickness (height) of 1 coin.

Solution:

The 50 coins form a cylinder with a volume of 27,480 mm³.

If the diameter is 21.18 mm, the radius of a coin will be $\frac{21.18}{2} = 10.59$ mm.

The volume of a cylinder $= \pi r^{2} h.$

The volume of all 50 coins is given as 27,480 mm³. We need to determine the height of a single coin.

$50( \pi r^{2} h)=27,480.$

$50(3.1415)(10.59^{2} )(h) = 27,480.$

$(17,615.662)(h)=27,480.$

$h= \frac{27,480}{17,615.662} = 1.5599$ mm.

So the thickness of 1 coin is 1.5599 mm.

How to solve question 15 and 16

Svet_ta [14]

Answer:

Step-by-step explanation:

16 is especially important, so start with it.

F = 5/9 * C + 32 Subtract 32 from both sides.

F - 32 = 5/9 C + 32 - 32 Combine

F - 32 = 5/9 C Multiply both sides by 9/5

9/5(F - 32) = 9/5 * 5/9 C Combine

9/5(F - 32) = C

Fifteen

V = pi * r^2 * h / 3 Multiply both sides by 3

3V = 3*pi * r^2 * h/ 3 Combine

3V = pi * r^2 * h Divide by pi

3V/(pi ) = r^2 * h Divide by r^2

3V / (pi * r^2) = r^2 * h / r^2 Combine

3V / (pi * r^2) = h
