What is the area of the base of the pedestal?
6.7 square feet
22.5 square feet
45 square feet
3,645 square feet
Answer:
45 square feet
Step-by-step explanation:
we know that
The volume of the pedestal (rectangular prism) is given by the formula
where
B is the area of the rectangular base of pedestal
we have
substitute the given values in the formula and solve for B
Answer:
45
Step-by-step explanation:
Answer:
20 months
Step-by-step explanation:
Let x represent the number of months.
We have been given that at one bank, Aaron would pay $2500 initially and $150 each month for the loan. So amount paid in x months would be .
We are also told that at another bank, Aaron would pay $3000 initially and $125 each month for the loan. So amount paid in x months would be .
To find the number of months when both loan payments will be the same, we will equate both expressions as:
Therefore, after 20 months both loan payments would be the same.
substitute the coordinates of the ordered pair into either equation to see if it produces a true statement
B.
substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each
C.
substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement
D.
substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement
Answer:
B
Step-by-step explanation:
When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)
B : 8/28
C : 9/16
D : 19/28

Answer:
9. 2a+5 ; 11. 2x+11y+4 ; 13. -a+3b-1 ; 15. (10c^2)-2c+5 ; 17. (5(a^2)(b^2))-(a(b^2))
Step-by-step explanation:
You should group each term with the same variables and then simplify
9. 9a + 8 - 2a - 3 - 5a
=(9a-2a-5a)+(8-3)
= 2a + 5
11. 7x + 2y + 5 - 5x + 9y - 1
= (7x-5x)+(2y+9y)+(5-1)
=2x+11y+4
13. -6+3a-b-4a+4b+5
=(3a-4a)+(-b+4b)+(-6+5)
=-a+3b-1
15. 8c^2 -c+3+2c^2 -c +2
=(8c^2 + 2c^2)+(-c-c)+(3+2)
=(10c^2)-2c+5
17. 6a^2b^2 + 3ab^2 -a^2b^2 -4ab^2
=(6a^2b^2 -a^2b^2)+(3ab^2 -4ab^2)
=(5(a^2)(b^2))-(a(b^2))
