mamaluj [8]

Answer:

  35 miles

Step-by-step explanation:

The segment addition theorem tells you ...

  DE + EF = DF

  125 + EF = 160

  EF = 35 . . . . . . . subtract 125

The distance from E to F is about 35 miles.

4 1/5 + 2 5/6 = ? <br><br> 6 1/6 <br> 6 1/30 <br> 7 1/4 <br> 7 1/30
grigory [225]

Answer:

7 1/30

Step-by-step explanation:

4 1/5 + 2 5/6

Get a common denominator of 30

4 1/4 = 4 1/5*6/6 = 4 6/30

2 5/6 *5/5 = 2 25/30

4 6/30 + 2 25/30

6 31/30

Rewriting

6 30/30 + 1/30

6 + 1 + 1/30

Cone a has a radius of 6 units and a height of 4. Sphere B has the same volume as cone A. Find the Radius of sphere B.
postnew [5]

Answer:

3.3

Step-by-step explanation:

to determine the answer

calculate the volume of the cone

the volume of the cone  = volume of the sphere

use the volume of the sphere to find the radius

Volume of a cone 1/3(nr^2h)

n = 22/7

r = radius  

h = height

(1/3) x (22/7) x (6^2) x 4 = 150 .86

volume of sphere = (4/3) x (n) x (r^3)

n = 22/7

r = radius

(4/3) x radius^3 x (22/7)  = 150.86

radius^3 = (3/4) x (7/22) x 150.86

radius^3 = 36

find the cube root of 36

radius = 3.3

37.71
