Answer:

\$(10-p)

Step-by-step explanation:

Nicholas used a $10 bill to pay for a granola bar that only costs p dollars.

To find much change Nicholas received, simply subtract the cost of granola bar from the amount of money Nicholas paid:

\$(10-p)

For example, if granola bar costs p=$4, then Nicholas gets

\$(10-4)=\$6

as a change.

An oblique cone has a radius of 4 units, a height of 8.5 units, and a slant length of 11.7 inches. What is the volume of the obl
trasher [3.6K]

Oblique Cone

The volume of the oblique cone is 144.49 cubic inches , if an oblique cone has a radius of 4 units, a height of 8.5 units, and a slant length of 11.7 inches.

Step-by-step explanation:

             An oblique cone has a radius of 4 units

             A height of 8.5 units

             A slant length of 11.7 inches

We have to use the slant height to calculate actual base

So in a right angle triangle when two sides are given the third side is calculated by

Root (sqr(11,7) - sqr(8.5)) = 8.03 units

\sqrt{11.7^{2}  - 8.5^{2} }

⇒ 8.03 units

Formula to calculate the volume of oblique cone,......................(1)

V = \frac{1}{3} bh

If r is the distance of the base of the height from the center of the circle [ this is because the base of the height is outside the oblique cone]

V = \frac{1}{3} \pi r^{2} h

Where r is the distance if the base of the height from the center of the circle [ this is because the base of the height is outside the oblique cone]

Here r = 8.03 - 4 = 4.03 units

Volume = \frac{1}{3}× 3.14 × 4.03 × 4.03 × 8.5

Volume = 144.49 cubic inches

Hence, the volume of the oblique cone is 144.49 cubic inches , if an oblique cone has a radius of 4 units, a height of 8.5 units, and a slant length of 11.7 inches.

What is the zero of the function below?<br> f(1) = 3v1 + 3 - 6
Reika [66]

Answer:

v1 = 1

Step-by-step explanation:

Solve for v1:

3 v1 - 3 = 0

Add 3 to both sides:

3 v1 + (3 - 3) = 3

3 - 3 = 0:

3 v1 = 3

Divide both sides of 3 v1 = 3 by 3:

(3 v1)/3 = 3/3

3/3 = 1:

v1 = 3/3

3/3 = 1:

Answer: v1 = 1
