Given:

Composite figure made of cylinder and two spheres.

To find:

The volume of the composite solid.

Solution:

Radius = 2 in

The value of π = 3.14

Volume of sphere:

$$V=\frac{4}{3} \pi r^3$

$$V=\frac{4}{3} \times 3.14 \times 2^3$

$$V=\frac{4}{3} \times 3.14 \times 8$

$V=33.49$

Volume of a sphere is 33.49 in³

Volume of two spheres = 2 × 33.49 = 66.98 in³

Radius of cylinder = 2 in

Height of cylinder = 8 - 2 - 2 = 4 in

Volume of cylinder:

$$V=\pi r^2 h$

V = 3.14 × 2² × 4

V = 50.24

Volume of cylinder = 50.24 in³

Volume of composite solid = Volume of two spheres + Volume of cylinder

= 66.98 in³ + 50.24 in³

= 117.2 in³

The volume of the composite solid is 117.2 in³.

On a field trip, there are 5 adult chaperones for every group of 20 students. There are 150 people in total on the trip. What pe

denis23 [38]

Answer:

80% of the people on the trip are children.

Step-by-step explanation:

To determine the percentage of the people on the trip that are children,

First, we will determine how many of the people are children.

From the question,

There are 5 adult chaperones for every group of 20 students, that is, out of 25 people, 5 are adult chaperones and 20 are students.

From the question, there are 150 people in total in total.

Let the number of children be x

If there are 20 students (children) in 25 people

Then, there will be x children in 150 people

x = (150 × 20) / 25

x = 120

Hence, there are 120 children.

To determine the percentage of the people on the trip that are children,

we will divide the number of children by the total number of people and then multiply by 100%

Number of children = 120

Total number of people = 150

∴ The percentage of the people on the trip that are children is

(120/150) × 100% = 0.8 × 100% = 80%

Hence, 80% of the people on the trip are children.

Write the equation through (2,5) parallel to the line through (8,0) and (0,8)

klio [65]

Answer:

y = -x + 7

Step-by-step explanation:

As we move from (8, 0) to (0, 8), we see x decreasing by 8 ('rise') and y increasing by 8 ('run'). Thus, the slope of this line is m = rise/run = 8/(-8) = -1.

Starting from y = mx + b and substituting 8 for x, 0 for y and -1 for m, we get:

0 = -1(8) + b, or b = 8

Then the equation of the line through the two given points is y = -x + 8. Any line parallel to this one has the same slope: m = -1.

Repeat the above work to find the y-intercept of the line parallel to y = -x + 8 that goes through (2, 5):

5 = -2 + b, or b = 7

Then the desired line (final answer) is y = -x + 7
