Answer:
3) C
Step-by-step explanation:
The question is asking which pair is equal. Work through each problem to solve.
8(2r) and 10r
16r ≠ 10r
6r + 3 and 9r
6r + 3 ≠ 9r
9(3r - 4) and 27r - 36
27r - 36 = 27r - 36
r + r + r + r + r and r⁵
5r ≠ r⁵
Answer:
Step-by-step explanation:
125/x=100/0.35
(125/x)*x=(100/0.35)*x - we multiply both sides of the equation by x
125=285.71428571429*x - we divide both sides of the equation by (285.71428571429) to get x
125/285.71428571429=x
0.4375=x
x=0.4375
now we have:
0.35% of 125=0.4375
Answer:
B
Step-by-step explanation:
V = (4/3) pi r^3
V = 1.333 * 3.14 * 11^3
11^3 = 1331
V = 1.333 * 3.14 * 1331
V = 5572
Answer:
No
Step-by-step explanation:
I'm not quite sure what a ratio table is, but I can explain it the way I understand it.
The initial ratio is 10:8 which is 1.25 as a decimal.
Now let's add five to each number to represent the kids joining the class, this will result in the following:
15:13 which is 1.153846154 as a decimal.
Therefore, the ratio doesn't stay the same just because you added the same number of people to each group.
Hope this helps :)
