Use the compound amount formula for continuous compounding:

A = Pe^(rt)

Here,

A = $3000e^(0.055^5) = $3950 (rounded up from $3949.59)

You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. Assume that the depth of the concrete is 4 in

Answer:

3.5 cubic yards of cement we need.

Step-by-step explanation:

Given : You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. Assume that the depth of the concrete is 4 inches.

To find : How much cement is needed, in cubic feet? How many cubic yards of cement do you need?

Solution :

The length of the side walk is 95 feet long.

The width of the side walk is 3 feet long.

The depth of the concrete is 4 inches.

Convert inches into feet,

1 inch = 0.083 feet

4 inch = $4\times 0.083=0.332$ feet

Volume of the cement required is given by

$V=l\times b\times h$

$V=95\times 3\times 0.332$

$V=94.62\ ft^3$

Converting volume into yards,

$1\ ft^3=0.037\ yd^3$

$94.62\ ft^3=3.50094\ yd^3$

Therefore, 3.5 cubic yards of cement we need.

Jodie bought some shirts for $6 each. Marge bought some shirts for $8 each. The girls spent the same amount of money on shirts

FrozenT [24]

<u><em>Answer:</em></u>

The least amount of money they could have spent is $24

<u><em>Explanation:</em></u>

To get the least amount of money they could have spent, we will need to get the lowest common multiple of both numbers (6 and 8).

This means that we need to find that least number that is found in both multiplication tables

Multiples of 6:

6 * 1 = 6

6 * 2 = 12

6 * 3 = 18

6 * 4 = 24

Multiples of 8:

8 * 1 = 8

8 * 2 = 16

8 * 3 = 24

Noticing the two multiples, we can note that the lowest common multiple is 24.

This means that the lowest amount they could have spent is 24

Hope this helps :)
