Answer:
Y=7x+9
Step-by-step explanation:
Y=mx + b
b= y-intercept
m=slope
Substitute:
Y=7x+9
The volume of the frustum is volume of the whole cone(A) minus the smaller cone(B) which is would give the volume of frustum(C) = 256cm³
<h3>Calculation of a frustum</h3>
The volume of cone A V=πr²h/3
Where radius = 20cm
The volume of cone B = V=πr²h/3
Where radius = 12cm
Therefore volume of frustum =
V=π * 20² * h/3 - π * 12² *h/3
The variables will cancel out each other
V = 20² - 12²
V = 400- 144
V = 256cm³
Therefore, the volume of the frustum(C) = 256cm³

Answer:
x=35
'x-10'=25 degrees
'x'=35 degrees
The last one is 120 degrees
Step-by-step explanation:
A straight line is 180 degrees
180-60=120
2x+110=180
2x=70
x=35
(15x^3y^-8)÷(5x^2y^-4)
= 3xy^-4
(3x)/ y^4
Start by multiplying six by 3 and getting 18. thendivide 23.15 by 18 = 1.2861111
that's the answer.
