A 13ft ladder leans against the side of a house . the bottom of the ladder is 10ft from the side of the house. how high is the top of the ladder from the ground

The answer would be the square root of 69 or 8.30662386

Step-by-step explanation:

Use pythagoreum theorum

a^2 + b^2 = c ^2

13 = Hypotenouse

10 = a or b

10^2 + b^2 = 13^2

100 + b^2 = 169

-100

b^2 = 69

square root both sides

b = square root of 69 or 8.30662386

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
