The number is 63, so the quotient is 2.
Two digit numbers divisible by 21:
21, 42, 63, 84
21: 2-1 = 1 * 3.5 = 3.5
3.5*2*1 = 7 but 7 does not equal 21
42: 4-2 = 2 * 3.5 = 7
3.5*4*2 = 28 does not equal 42
63: 6-3 = 3*3.5 = 13.5
3.5*6*3 = 63 :)
Check:
21(6-3)=21(3)= 63 :)
3.5(6)(3) = 21(3) = 63 :)
63: 6/3 = 2
Answer:
There are 55 rooms
Step-by-step explanation:
There are 165 beds in the hospital. Each room contains 3 beds. In order to find the number of beds per room, take the total number of beds and divide it by the number of rooms in each bed. 165/3=55. There are 55 rooms in the hospital, all containing 3 beds.
Hope this helps!
We have been given that the volume of a cone is 113.04 cubic mm. We are asked to find the approximate volume of a sphere that has the same height and a circular base with the same diameter.
We know that volume of cone is 
.
The height is equal to the diameter. We know that diameter is 2 times radius, so we can represent this information in an equation as:
Upon substituting in volume of cone, we will get:
We know that volume of sphere is 
.
Upon comparing volume of cone with volume of sphere, we can see that volume of sphere is 2 times the volume of cone.
Since 
, so volume of sphere would be:
Therefore, volume of sphere would be 226.08 cubic mm.

Answer: 2 + √10 , 2 − √10
Step-by-step explanation:
-5x(x-4) = -30
divide by -5
x(x - 4) = -30
distribute the x
x^2 - 4x = 6
move the 6 to the left to have the equation equal zero
x^2 - 4x - 6 = 0
plug into the quadratic formula & solve
x
= 2 + √10 , 2 − √10
