Percent increase in the numbers of cars washed is 75%

Step-by-step explanation:

Given:

Number of cars washed in First weekend by the students =40 cars

Number of cars washed in second weekend by the students= 70 cars

To Find:

Percentage of increase in the number of car washed=?

Solution:

we know that

Percentage Increase=Final Value−Starting Value|Starting Value x 100

According to our question

$\text{Percentage Increase in cars }= \frac{\text{cars washed in second week} -\text{cars washed in first week}}{\text{cars washed in the first weekend}}\times 100$

Substituting the values,

percentage of increase in the cars = $\frac{70-40}{40}\times100$

percentage of increase in the cars = $\frac{30}{40}\times100$

percentage of increase in the cars = $0.75\times100$

percentage of increase in the cars =75

What are the measures of angles B and C? O ZB = 15°; ZC = 165°
O ZB = 65°; ZC = 115°
O ZB = 65°; ZC = 65°
O ZB = 15°; ZC = 15°
