Which statements are TRUE? Select all that apply. Marisa drives 112 miles in 1 hour and 45 minutes, which means her speed is 64
valentinak56 [21]

Answer: See explanation

Step-by-step explanation:

a. Marisa drives 112 miles in 1 hour and 45 minutes, which means her speed is 64 miles per hour.

Speed = Distance / Time

= 112 / 1 45/60

= 112 / 1 3/4

= 112 × 4/7

= 64 miles per hour.

TRUE

b . If 6 pens cost $7.74, then 7 pens cost $9.03.

Cost of one pen = $7.74/6 = $1.29

Cost of 7 pens = $1.29 × 7 = $9.03

TRUE

c. If Raymond drives at a speed of 57 miles per hour, then it takes him 4 hours and 10 minutes to drive 256.5 miles.

Speed = Distance / Time

Speed = 256.5 / 57 = 4.5 = 4 hours 30 minutes

FALSE

d. If 17 identical cans of soup cost $38.59, then 3 of the cans must cost $6.81.

Cost of one can = $38.59 / 17 = $2.27

Cost of 3 cans = $2.27 × 3 = $6.81

TRUE

e. Mr. Mayes buys two dozen eggs for $8.40, which means that he pays 70 cents per egg.

A dozen = 12

2 dozens = 12 × 2 = 24

Cost of one egg = $8.40 / 24 = 0.35 = 35 cents

FALSE

Tori took out A $350,000 loan in order to purchase a house. She has to pay an interest of 5.2% over 35 years. how much interest
Dmitrij [34]

Hello from MrBillDoesMath!


Answer:

Interest paid = $ 1,713,568.73

Monthly p[payment = $4913.25


Discussion:

From the "compound interest formula:

A = final amount

P = Initial amount (Principal)

r = yearly interest rate

n = number of years of accumulation.


In our case,

A = 350000( 1 + .052)^35 =

      350000 (5.90)  =                  (approx)

      $2,063,568.73

Interest =  $2,063,568.73 - 350000 =  $ 1,713,568.73


There are 35 *12 = 420 months in 35 years. So the monthly payment would be   ($2,063,568.73 / 420)  = $4913.25



Thank you,

MrB
