Step-by-step explanation:
Volume of a cylinder : πr^2*height.
Volume : 150cm^3
height : 7.2m
π =3.14
150 = 3.14*r*r*7.2
150=22.608*r*r
r^2= 150/22.608
=150/23cm^2
r=√6.5
r=2.569cm
r=2.6cm
Given:
Jamie receives 15% commission on magazine subscriptions.
One week her sales totaled $860.
To find:
Her commission.
Solution:
We have,
Total sales of one week = $860

Therefore, the amount of commission is $129.
Answer:
a)
b)
c)
Step-by-step explanation:
We are given the following in the question:
1. Equivalent expression
Since all the terms are like terms, we can write,
2. Sum of given expression
3. Standard form of the expression
which is the required standard form of the given expression.
The size of the large cabinets door = 2.3 * 11.5 = 26.45 inches
the board size in inches = 10 1/2 * 12 = 126 inches
number of doors = 126 / 26.45 = 4.76
so the number of doors = 4 doors
Answer:
Abel to Ben: 6
Abel to Carl: 3
Ben to Carl: 0.5
Step-by-step explanation:
First we formulate the problem in equations:
Abel = 6 * Ben
Cale = Abel / 3
If Cale's score is Abel's score over 3, so Abel's score is 3 times Cale's score.
If Abel's score is 6 times Ben's score, and 3 times Cale's score, then Cale's score is 2 times Ben's score (so Ben's score is 0.5 times Cale's score)
So, the ratio between all scores are the following:
Abel to Ben: 6
Abel to Carl: 3
Ben to Carl: 0.5
