Kim and kelly are saving for new roller skates. so far kim has saved $70 saved and can earn $5 per hour babysitting. kelly has $30 saved and can earn $7 per hour at her family's restaurant. after how many hours will kim and kelly have the same amount saved? what will that amount be?

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
