Mrs. Robinson’s goal for each of her students is to read for 25 hours in one grading period. Kat has read for 2 1/2 hours so far and plans to read for 30 minutes each day. Aaron has read for 1 hour so far and plans to read for 45 minutes each day. Which statement is true? Kat will meet the goal 13 days earlier than Aaron.

Aaron will meet the goal 13 days earlier than Kat.

Kat will meet the goal 22 days earlier than Aaron.

Aaron will meet the goal 22 days earlier than Kat.

what is the graph

step-by-step explanation:

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

h= 12 inches
