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

If an arena hosts a concert for the same artist two years in a row and earns $1,500,000 in revenue during year one and $975,000

user100 [1]

The percentage decrease is 35%.

Step-by-step explanation:

Given,

Revenue generated in first year = Old value = $1,500,000

Revenue generated in second year = New value = $975,000

Change = New value - Old value

Change = 975000 - 1500000= -$525000

The negative sign indicates the decrease.

Percent decrease = $\frac{Change}{Old\ value}*100$

Percent decrease = $\frac{525000}{1500000}*100\\$

$Percent\ decrease=\frac{52500000}{1500000}\\\\Percent\ decrease = 35\%$

The percentage decrease is 35%.
