Answer:
A) y=x+1
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(9-5)/(8-4)=4/4=1
y-5=1(x-4)
y-5=x-4
y=x-4+5
y=x+1
Answer:
Find the volume of the sphere.
Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.
The radius is 1
Volume =
or 4.19
Step-by-step explanation:
Given
Radius, r = 1
Required
Find the volume of sphere
Volume of a sphere is calculated using the following formula

Where V = Volume and r = radius
By Substitution,

Solving further to get the numerical value of volume;
We have to substitute 3.14 for π

V = 4.19 to the nearest hundredth
Answer:
20.5 : 61.5
Step-by-step explanation:
1:3
1 + 3 = 4
82 ÷ 4 = 20.5
ratio of 1:3
1 × 20.5 = 20.5
3 × 20.5 = 61.5
20.5 : 61.5
If there is 23 classrooms and each has 10 then you would have to times 23 by 10 - 23x10=230
