Answer:
She swims 8 kilometers a week 8KM
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
66 ÷ a = a + 2, anything that has R2 can also be rewritten to be plus 2. Then if you move 2 to the other side it becomes, (66 ÷ a) - 2 = a. Moving a to the other side will create this equation 66 - 2 = a x a. Therefore, 64 = a ^ 2. You just have to find the square root of 64 then.
Answer:
subtracting 14 from sides of the number sentence
Step-by-step explanation:
14 + n = 84
Since 14 is being added to n, you need to subtract 14 from both sides to solve for n.
Answer: subtracting 14 from sides of the number sentence

(2nd option)
Step-by-step explanation:
So 20% of 950 = 1/5 × 950
Answer:
The volume of the tank is 1235ft³
Step-by-step explanation:
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 13ft
π = 3.14
r = radius = 5.5ft
v = (π * r²) * h
we replace the unknowns with the values we know
v = (3.14 * (5.5ft)²) * 13ft
v = (3.14 * 30.25ft²) * 13ft
v = 94.985ft² * 13ft
v = 1234.805ft³
Round to the nearest whole number
v = 1234.805ft³ = v = 1235ft³
