In a certain classroom ,12.5% of the students own at least one pet. if there are 32 students in the classroom, how many students do not own any pet

28

Step-by-step explanation:

Given that 12.5% of students own at least 1 pet, then the percentage of students who do not own a pet is

100% - 12.5% = 87.5%

Calculate 87.5% of 32, that is

× 32

= 0.875 × 32 = 28 ← number of students who do not own a pet

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
