The diameter of a large sphere is 4 times the diameter of a small sphere. The surface area of the large sphere is how many times

Sever21 [200]

Surface Area of a Sphere = 4π(d/2)²
Let the smaller sphere's diameter be just a sample of 4 units in diameter and let the large spheres diameter be 4 times that of the smaller sphere.

Small Sphere: 4π(4/2)² = 16π units²
Large Sphere: 4π(16/2)² = 256π units²

256π / 16π = 16 times

The large sphere has a surface area 16 times that of the smaller one.

What is the slope of a line that contains the points (-8,7) and (-4,-5)?

Pani-rosa [81]

Answer:

-3

Step-by-step explanation:

To find the slope given two points

m = (y2-y1)/(x2-x1)

= (-5-7)/(-4- -8)

= (-12)/(-4+8)

=-12/4

= -3

60:92=105:n what is n?

PIT_PIT [208]

Hey! I'll provide you the answers!

First you want to simplify the equation using cross-multiplication.

$15n = 2415$

Finally, you would want to divide both sides by 15.

n = 161
