Answers

Answer 1
Answer:

Answer:

33+15w=3w-w+4w

33+15w - 15w=3w-w+4w -15w

33 = 2w + 4w -15w

33 = 6w -15w

33 = -9w

33/9 = -9/9w

3.66 = w

Step-by-step explanation:

33+15w=3w-w+4w

33+15w - 15w=3w-w+4w -15w

33 = 2w + 4w -15w

33 = 6w -15w

33 = -9w

33/9 = -9/9w

3.66 = w

Question 3Mr. Winking is purchasing a car and needs to finance $24,000 from the bank with an annual percentage rate (APR) of
4.8%. He is financing it over 5 years and making monthly payments. What is the monthly payment?
$104.54
$378.21
$450.71
$1225.56

Answers

Answer:

The monthly payment, PMT = $450.71

Therefore the correct option is C.) $450.71

Step-by-step explanation:

i) Value of Loan, or Present value, PV = 24000

ii) Annual percentage rate , APR = 0.048

iii) number of periods, n = 12

iv) periodic interest, R = APR / n  = 0.048 / 12 = 0.004

v) number of years, t = 5

v) Monthly Payment, PMT =  (PV* R)/(1 - (1 + R)^((-1* n * t))) = (24000 * 0.004)/(1 - ( 1 + 0.004)^(-60)) = $450.71

Heather wants to buy a new refrigerator, but she only has room for one that is 18 ft3 or less. Which set of dimensions represent a refrigerator that Heather can buy?

Answers


As soon as I read the words "which set" in your question, I knew that
there's a list of choices on the sheet where you copied the question
from, but that you didn't copy the list along with the question.

All I can tell you is this: 
Find a choice where, when you multiply all three dimensions together,
the product is 18 ft³ or less.  That choice is a set of dimensions that
represents a refrigerator that will fit in Heather's kitchen. 

(For all I know, there may be more than one suitable choice on the list that
you didn't include with the question, so you'd better check all of them.)

Answer:

the answer is a

A) 2 ft. wide x 2.5 ft. long x 3 ft. tall  

B) 2 ft. wide x 2.5 ft. long x 4.5 ft. tall  

C) 2.5 ft wide x 3 ft. long x 4 ft. tall  

D) 2.5 ft. wide x 2 ft. long x 4 ft. tal

Step-by-step explanation:

2 ft. wide x 2.5 ft. long x 3 ft. tall because 2 x 2.5 x 3 = 15 ft3, which is less than 18 ft3.
