Answer:
-21
28
Step-by-step explanation:
1) if r = -4
Substitute r = -4 in 3r - 9
= 3 * (-4) - 9
= -12 - 9
= -21
2) ( 4 / 7 ) * x = 16
4 * x = 16 * 7
x = 4 * 7
x = 28
Answer:
4/10, 6/15, 8/20, 10/25
Step-by-step explanation:
Answer:
Cube A side length = 5 in
Cube B side length = 6 in
Cube A has a smaller side length than cube B
or, same as
Cube B has a larger side length than cube A
Step-by-step explanation:
The volume of a cube is given by s³ where s is each side length
Cube A has volume = 125 cu in
Cube A side = ∛125 = 5 in
Cube B has a face area of 36 sq in
Face of a cube area is given by s²
So cube B side = √36 = 6 inches
Cube A has a smaller side length than cube B
or
Cube B has a larger side length than cube A
Depending on what the question is asking for(question has been chopped off during copy/paste)
All your doing is rounding sweetie
First question: you're given , , , and . So the value of the account after 3 years is
making the answer B.
Second question: and . APY is given by
so the APY in this case is
making the answer D.
