To find the least common multiple, first think about the different multiples of 15, 6, and 10 and then we need to find the smallest multiple that they have in common. We can start by finding the multiples of each number.

Find two numbers whose ratios is 3 to 5 and whose sum is 88

Tomtit [17]

Answer:

33 and 55

Step-by-step explanation:

$\frac{x}{y}: \frac{3}{5}$

x + y = 88

3 + 5 = 8

$y(\frac{x}{y}): y(\frac{3}{5})$

$x= \frac{3}{5}y$

$y+\frac{3}{5}y=88$

$\frac{8y}{5}=88$

$5(\frac{8y}{5})=5(88)$

8y = 440

8y ÷ 8 = 440 ÷ 8

y = 55

x + y = 88

x + 55 = 88

x + 55 - 55 = 88 - 55

x = 33

A cube has a side length of 8 inches.

Kazeer [188]

The answers are $8^{3}$ and 8 · 8 · 8

Explanation:

The volume of a cube or space a cube occupies is calculated by multiplying the length, height, and width. Additionally, because in a cube all sides are equal in length, the formula for volume is V= $s^{3}$ . According to this, if the side length is 8 inches the volume can be represented as $V = 8^{3}$ or V= 8 · 8 · 8 because the symbol · represents multiplication. Also, this can be solved as V = 512 cubic inches. This makes the following options correct: $8^{3}$ and 8 · 8 · 8.
