Hi Scarletflame
x ≥ -8 x 4
x ≥ -32
All u have to do is multiply both sides by 4 and multiply 8 and 4 to 32
Answer: C) or the third option.
<span>(a) What is the capacity of the container?
Volume = length * width * height
V = 4ft * 2ft * 3ft
V = 24 ft</span>³
<span>
(b) How much material was used to make the container?
Surface area = sum of 6 faces of the prism
4 ft x 3 ft = 12 ft</span>² → 12 ft² x 2 = 24 ft²
<span>4 ft x 2 ft = 8 ft</span>² → 8 ft² x 2 = 16 ft²
<span>2 ft x 3 ft = 6 ft</span>² → 6 ft² x 2 = 12 ft²
<span>
Surface area = 24 ft</span>² + 16 ft² + 12 ft² = 52 ft²<span>

Answer:
D. 15
Step-by-step explanation:
3x-10=2x+5
to solve subtract 2x from both sides
(3x - 2x) - 10 = 2x + 5 - 2x
add 10 to both sides
x -10 + 10 = 5 + 10
x = 15
Answer:
15 boys selected
Step-by-step explanation:
Given
--- The population
--- The sample selected
-- The proportion of boys
Required
The expected number of boys selected
The expected number is calculated by multiplying the sample size by the proportion of boys.
So, we have:
--- approximated
6 = equal or more than 6
thus each day kathy swims ≥ 6 laps
