Work out the lengths of sides a and b. Give your answers to 1 decimal place.

Tju [1.3M]

Answer:

$A = \sqrt{89}$

$B = \sqrt{145}$

Step-by-step explanation:

$1)\ 8^2 + 5^2 = A^2$

$2)\ A^2 = 64 + 25$

$3)\ A^2 = 89$

$4)\ A = \sqrt{89}$

$1)\ B^2 + 12^2 = 17^2$

$2)\ B^2 + 144 = 289$

$3)\ B^2 = 145$

$B = \sqrt{145}$

Given:

Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale.

To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale.

To find:

The number of ounces in each container of ginger ale.

Solution:

Let n be the number of ounces in each container of ginger ale.

According to the question, the ratio of fruit juice and ginger ale is 2:5. it means,

$\dfrac{\text{Fruit juice}}{\text{Ginger}}=\dfrac{2}{5}$

$\dfrac{18}{\text{Ginger}}=\dfrac{2}{5}$

$5\times 18=2\times \text{Ginger}$

$90=2\times \text{Ginger}$

Divide both sides by 2.

$45=\text{Ginger}$

So, ginger required for punch is 45 ounces.

Number of containers = 3

Number of ounces in each container of ginger ale = n

Number of ounces in 3 containers of ginger ale = 3n

Now,

$3n=45$

Divide both sides by 3.

$n=15$

Therefore, 15 ounces are in each container of ginger ale.
