Answer:
A = 20% B = 36%
Step-by-step explanation:
35 in total bought
2/10 = who bought model A = 20%
16+9 = 25 => 9/25 who bought model B = 36%
Answer:

Step-by-step explanation:
Let r be the radius ( in feet ) of the cone,
So, the diameter of the cone = 2 × radius = 2r feet,
∵ The diameter of the base of the cone is three times the height,
If h represents the height of the cone,
⇒ 2r = 3 × h,
⇒
feet,
∵ Volume of a cone,

Where,
R = radius, H = height,
Thus, the volume of the given cone is,



Differentiating with respect to t ( time )

We have,




Answer:
w=10
Step-by-step explanation:
You would have to set 5w-4=46.
5w-4=46
Add 4 to both sides
5w=50
Divide both sides by 5
w=10
Two angles are complementary when they add up to 90 degrees<span>
</span><span>smaller angle = x
</span><span>larger angle = 9x
</span>
x + 9x = 90
10x = 90
x = 90/10
x = 9° ← smaller angle
larger angle = 9x = 9 * 9 = 81°
