Answer:
$728
Step-by-step explanation:
The formula for simple interest is I = PRT, where I = interest earned/paid, P = principal amount deposited or borrowed, R = rate of interest as a decimal, and T = time in years.
I = PRT
I = (4000)(0.052)(3.5)
I = 728
Answer:
$4000
Step-by-step explanation:
so $2800 was the starting price
100%-30%=70%
So 2800=70%
2800/7=400
400=10%
400*10=$4000
Answer:
7 dogs
Step-by-step explanation:
$30/3 = how many dollars per dog
$10 per dog he washes
$70/$10 = 7, he washes 7 dogs
6.37² x 3.1
First is Exponents (6.37²):
40.6 x 3.1
Then, Multiplication:
40.6 x 3.1 = 125.9.
To remember the order of operations, the term PEMDAS can be used. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.)
You do the equation in the order of the letters.
Example:
(5-2)5 + 2² / 6 -1 = ?
First, Parentheses:
(3)5 + 2² / 6 - 1
Then, Exponents:
(3)5 + 4 / 6 - 1
Then, Multiplication:
15 + 4 / 6 - 1
Then, Division:
15 + 0.7 - 1
Then, Addition:
15.7 - 1
Then, Subtraction:
14.7
So that means, (5-2)5 + 2² / 6 -1 = 14.7
72 inches equals 2 yards.
