Mindy conducted a survey of the phones in four stores and wrote the following observations:

5 of the 8 phones in store 1 were smartphones
13 of the 22 phones in store 2 were smartphones
22 of the 30 phones in store 3 were smartphones
12 of the 25 phones in store 4 were smartphones

based on the survey, which store had the greatest percentage of smart phones?

store 1
store 2
store 3
store 4

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

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
