75.00 , what is the percent ?

Answers

Answer 1
Answer:

Answer:

16 2/3 %

Step-by-step explanation:

Since the price went down, we are find the percent decrease.

Percent decrease = (original price - new price)/ original price

                               = (90 - 75)/90

                                =15/90

                                  .1666666666666

Changing to percent form

                                      16.6666666666666666666666%

                                       16 2/3 %

Simplify the expression 6x+12y+5+2y+8 what is the coefficient of y and what is the constant

Answers

we want to find the coeficient of the y terms when added together so find all the y terms

+12y and +2y
we add them together
12y+2y=(12+2)y=(14)y=14y
coeficient is 14


the constant is the number that is set already or the number that doesn't have it multiplied by a placeholder exg. 4 is a constnat but 4x is not so find the constants
+5 and +8
we add
5+8=13
the constant is 13


y coeficient=14
constant=14
6x+12y+5+2y+8
= 6x+ (12y+2y)+ (5+8) (combine like terms)
= 6x+ 14y+ 13

Coefficient of y: 14
Constant: 13

Hope this helps~

What is the volume of the right prism?A. 50 in3

B. 600 in3

C. 1200 in3

D. 400 in3

Answers

Volume of a right prism = Area of the base * height

the base is the right triangle.
Area of a right  triangle = ab/2
a = 15 inches ; b = 8 inches

Area of a right triangle = (15in * 8in)/2 = 120 in² / 2 = 60 in²

V = B * h
V = 60 in² * 10 in 
V = 600 in³  Choice B.
