Answer:
$11.25
Step-by-step explanation: multiply .75 by 3 then multiply that answer by 5 and get your answer.
X is amount of plates 10lbs and f(x) is the function
Answer:
F 8.4
Step-by-step explanation:
4 [ 4.5 - 2(1.2)]
First, multipy 2 and 1.2
2 x 1.2 = 2.4
Then subtract 2.4 from 4.5
4.5 - 2.4 = 2.1
Last, multiply 2.1 from 4
4 x 2.1 = 8.4
Answer:
False
Step-by-step explanation:
No options is attached to the question. However, I'll assume it's a true or false question.
Represent the radius with r.
The circumference is calculated as:
X = 2πr
When the radius is doubled, the new radius R is
R = 2r
And the new circumference, C is:
C = 2πR
Substitute 2r for R
C = 2π * 2r
C = 4πr
Factorize the above equation.
C = 2 * 2πr
Recall X = 2πr;
The expression becomes:
C = 2 * X
C = 2X
This means that the circumference is doubled, not quadrupled.
Hence, the statement is false.
