This problem has to do with Fahrenheit and Celsius
Vinvika [58]
F = 1.8C + 32

С = -10   ⇒   F = 1.8·(-10) + 32 = 14   ⇒   (-10, 14)
С = 0      ⇒   F = 1.8·(0) + 32 = 32      ⇒   (0, 32)
С = 10    ⇒   F = 1.8·(10) + 32 = 50    ⇒   (10, 50)
С = 20    ⇒   F = 1.8·(20) + 32 = 68    ⇒   (20, 68)

Please help!!

Given:

The radius of the cone = 14 ft

The slant height of the cone = 27 ft

To find the lateral surface area and the total surface area of the given cone.

Formula

The lateral surface area of the cone is

LSA = \pi rl and

The total surface area of the cone is

TSA = \pi r^{2} + \pi r l

where,

r be the radius and

l be the slant height of the cone.

Now

Taking r = 14 and l = 27 we get

LSA = \pi (14)(27) sq ft

or, LSA = 1187.5 sq ft

Again,

TSA = \pi(14^2)+\pi (14)(27) sq ft

or,TSA = 1803.3 sq ft

Hence,

The lateral surface area of the cone is 1187.5 sq ft and the total surface area of the cone is 1803.3 sq ft. Option C.

melomori [17]
75+ 15x ≥ 140
⇒ 15x ≥ 140-75
⇒ 15x ≥ 65
⇒ x ≥ 65/15
⇒ x ≥ 13/3
⇒ x ≥ 4 1/3

Final answer: x ≥ 4 1/3~
