Hayley borrowed $1,854 from her parents. She agreed to repay them in equal installments throughout the next 18 months. How much

Serggg [28]

Answer: $ 618

Step-by-step explanation:

Money borrowed = $1,854

Total months taken to repay = 18 (Number of installments)

Money paid per month = $\dfrac{\text{Money borrowed}}{\text{Number of installments}}$

$=\dfrac{1854}{18}=\$103$

Now , money paid in 1 year = 12 x $ 103 =$ 1236 [1 year = 12 months ]

After a year , Haley still owe = $1,854 - $ 1236= $ 618

Hence, Haley still owe her parents $618 after a year .

What is the length of the diagonal of a 10 foot by 8 foot rectangle?

zloy xaker [14]

Diagonal of a rectangle formula:

Diagonal = √l² + w²
Diagonal = √10² + 8²
Diagonal = √100 + 64
Diagonal = √164
Diagonal = 12.806 feet.

Or you can use the pythagorean theorem. The diagonal of a rectangle is the hypotenuse of a triangle.

a² + b² = c² ; where a and b represents the lengths of the triangle and c is the hypothenuse. In this case, the lengths are 10 ft and 8ft.

10² + 8² = 100 + 64 = 164 ; This represents c².
c = √c² = √164 = 12.806 ft
