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

5x-4y when x=-2 and y=3
scoray [572]

Answer:

=-22

Step-by-step explanation:

first you fix the x and y into the eqution.

5(-2)-4(3)

Mulitiply and divide (left to right)

5(-2)=-10

mulitply and divide (left to right)

4(3)=12

so the would make the problem look like this

-10-12

add and subtract (left to right)

-10-12=-22

If there are 12 values in a data set in order from smallest to largestwhat is the median of the data set
ankoles [38]
The median would be the average between the 2 numbers.
Ex :
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
The average between 6 and 7 would be 6.5, so the median would be 6.5.

Does it matter which coordinate is (x1,y1) and (x2,y2) or can I just choose which coordinate I want it to be?​
zubka84 [21]

Answer:

Technically not on a graph but on a table yes it matter but here if I were you I would do (2,2) and (-1,-4)

Step-by-step explanation:   y=mx+b

(2,2) and (-1,-4)                  2=2(2)+b                     Answer is: y=2x+(-2)

x1 y1         x2 y2                2=4+b

-4-2=-6                           -2=b

-1-2=-3                    y-intercept

m=2

slope
