Good morning,
Answer:
5 + 12 ≤ x ⇔ 12 ≤ x − 5 ⇔ x − 5 ≥ 12.

Answer:
Step-by-step explanation:
Given, water is filling the bathtub at 60 liters per minute
Thus it follows that after minutes, there will be 60 times liters of water
So there will be liters of water in the bathtub after minutes.
Answer:
slant length = 35 cm
Step-by-step explanation:
A right cone has the vertex directly above the center of the base . The surface area of the right cone can be represented below.
surface area = πr(r + l)
where
r = radius
l = slant height/length
surface area = πr(r + l)
r = 10/2 = 5 cm
surface area = 628 cm²
Therefore,
628 = π × 5(5 + l)
628 = 5π(5 + l)
628 = 25π + 5πl
628 = 25 × 3.14 + 5 × 3.14 × l
628 = 78.5 + 15.7l
628 - 78.5 = 15.7l
549.5 = 15.7l
divide both sides by 15.7
l = 549.5/15.7
l = 35 cm
slant length = 35 cm
It would rotate 360 times in three hrs.
