What is the volume of a cone (in cubic inches) with a radius of 6 inches and a height of 3 inches? Use 3.14 for pi. Round your a
Gre4nikov [31]
V = 1/3 * (pi) * r^2 * h
(pi) = 3.14
r = 6
h = 3

V = 1/3 * (3.14) * 6^2 * 3
V = 1/3 * 3.14 * 36 * 3
V = 1/3(339.12)
V = 339.12 / 3
V = 113.04 cubic inches <==

a 10 foot ladder is leaning against the wall. the bottom of the ladder is 4ft from the base of the wall. which of the following
Pie

Answer:

The height of the wall is 9.17ft

Step-by-step explanation:

The length of the ladder is 10ft

Distance from the foot of the ladder to the wall is 4ft

The height of ladder is unknown.

To solve this question, you'll require a pictorial illustration of the situation. Kindly check attached document for that.

Since it's a right angle triangle, we have two sides with one sides unknown, we can use pythagorean theorem to find the third side.

The hypothenus (x) is 10ft

The adjacent is (y) 4 ft

The opposite (z) (height of the wall) is unknown.

X² = Y² + Z²

10² = 4² + Z²

100 = 16 + Z²

Z² = 100 - 16

Z² = 84

Z = √(84)

Z = 9.165 = 9.17ft

The height of the wall is 9.17ft

If you can help me with this whole thing i will be forever in your dept
Setler79 [48]

Answer:

Answer:

6 days

210 pages

Step-by-step explanation:

As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.

Now since he reads 35 pages per day.

Then mathematically;

y = 35x

For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)

To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that

Also; y = 30(x + 1)

Equating the two situations

35x = 30(x + 1)

35x = 30x + 30

35x -30x = 30

5x = 30

x = 30/5

x = 6 days

This means that it will take Amir 6 days to catch Jese.

The number of books they would have read by then is y = 35x = 30(x + 1)

= 35 * 6 or 30(6+1)

= 210
