Step-by-step explanation:

the distance of a vertex on the 2 outgoing sides to the touching points with the inscribed circle is the same for both sides.

and that applies to all 3 vertexes.

so, we know for the top left vertex the distance to both touching points is 4.

that means the distance to the touching points from the bottom left vertex is 7-4 = 3.

and that means that the distance to the touching points from the bottom right vertex is 16-3 = 13.

so, x = 13

it is the distance to one of the touching points for the bottom right vertex.

and the perimeter of the triangle is therefore

7 + 16 + (13 + 4) = 40

Answer:

see below

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We can find the radius from the diameter

r = d/2 = 34/2 = 17

V = (3.14) (17)^2 * 27

V =24501.42 m^3

The surface of a cone is found by

SA = pi r^2 + pi r l where l is the slant height

We can find the radius from the diameter

r = 8/2 = 4

SA =(3.14) * 4^2 + 3.14 * 4*7

=50.24+87.92

138.16 in^2

The lateral surface area of a pyramid is found by taking the area of the sides

LSA = 4 * the area of a triangle

we multiply by 4 since there are 4 sides

= 4 * 1/2 b*h where b is the base of the triangle and h is the height of the triangle. (in this case it would be the slant height)

= 2 * 8 *22

=352 m^2

A frog is climbing out of a well that is 11 feet deep. The frog can climb 3 feet per hour but then it rests for an hour, during

Dimas [21]

Answer:

It takes the frog 7 hours to get out of the well.

Step-by-step explanation:

We know that the well is 11 feet deep and the frog can climb 3 feet per hour.

Each time it climbs, it rests for an hour, and decreases its height by 1 foot.

So, if the frog reaches 3 feet in the first hour, then in the next hour it is 2 feet.

Lets calculate with the same pattern:

1st hour: 3 feet

2nd hour: $3-1=2$ feet

3rd hour: $2+3=5$ feet

4th hour: $5-1=4$ feet

5th hour: $4 +3= 7$ feet

6th hour: $7-1=6$ feet

5th hour: $6+3=9$ feet

6th hour: $9-1=8$ feet

7th hour: $8+3= 11$ feet

Therefore, it takes the frog 7 hours to get out of the well.

The perimeter of the parallelogram is 102 feet. Find m. Write your answer as a decimal or mixed number. The length is 3m and the

Ann [662]

m is 48 because since they said perimeter you would have to add 3 twice and then subtract is with 102 which is 96 the divide 96 by 2 and you would get 48.
