In the diagram triangles ABE and ACD are similar.

jolli1 [7]

Answer:

p = 7.2

q = 6.4

Step-by-step explanation:

if the triangles are similar then the side lengths must be proportional :

AC/BA = CD/BE

9/5 = p/4 cross multiply expressions

5p = 36 divide both sides by 5

p = 7.2

same goes for q

9/5 = (q+8)/8 cross multiply expressions

72 = 5(q+8) divide both sides by 5

14.4 = q+8 subtract 8 from both sides

6.4 = q

A candle maker has 4 1/2 pounds of clear wax. He wants to cut the wax into pieces that are 2/3 pound each. How many 2/3 pound pi

prisoha [69]

Answer:

a) 10 pieces of 2/3 pound can be made.

b) 0.54 pounds of wax is left over.

Step-by-step explanation:

Total amount of clear wax available = $4\frac{1}{2} = \frac{9}{2}$ pounds

So, the maker has in total 4.5 pounds of wax

Now, The weight of each piece = $\frac{2}{3} = 0.66$ pounds

To find the number of pieces that can be made out of 4.5 pounds of wax,

let that number = n

So, $n = \frac{\textrm{Total weight of the clear wax}}{\textrm{Weight of each wax}}$

or, n = $n = \frac{4.5}{0.66} = 6.81$

So, nearly 6 pieces can be made completely out of the clear wax

Left over amount of wax = Total weight - Weights of the pieces made

= 4.5- 6(0.66)

= 0.54 pounds

Hence, 0.54 pounds of wax is left over

Assume the world catch of fish in 1950 was 12 million tons and in 1955 it was 96 million tons.

Rama09 [41]

The rate of change is 16.8 million tons per year

Solution:

Given that, the world catch of fish in 1950 was 12 million tons and in 1955 it was 96 million tons

The average rate of change is given by formula:

$\text{ Average rate of change } = \frac{\text{ change in value }}{\text{ number of years }}$

Value in 1950 = 12 million tons

Value in 1955 = 96 million tons

Change in value = value in 1955 - value in 1950

Change in value = 96 million - 12 million = 84 million tons

Number of years = 1950 to 1955 = 5 years

Substitute the given values in formula,

$\text{ Average rate of change } = \frac{84 \text{ million tons}}{5} = 16.8 \text{ million tons}$

Thus rate of change is 16.8 million tons per year
