Answer:

x = 1

Step-by-step explanation:

First, you need to find out what the measure of the angle is so we add the two angles we know and then subtract that by 180.

64 + 85 = 149

180 - 149 = 31

This means that

4x + 27 = 31

So know we solve for x which results in the answer being

x = 1

A right circular cylinder has a base radius of 5 centimeters and a height of 12 centimeters. What is the volume of this cylinder?

Answers

The formula of a cylinder is V=πr^2 h
The radius is 5cm and the height is 12cm

V=π5^2 12
V=300π cm cubed

Your answer is B) V=300π cm cubed

The volume of right circular cylinder is 942 cubic cm.

What is volume?

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

Given : A right circular cylinder has a base radius of 5 centimeters and a height of 12 centimeters.

To find : What is the volume of this cylinder?

Solution : The formula of volume of right circular cylinder is:

The formula of a cylinder is V=πr^2 h

now, we have,

The radius is 5cm and the height is 12cm

where, r is the radius r= 5cm

h is the height h=12 cm

so, we get,

Volume of the cylinder = πr²*h

Substitute the value in the formula,

V = π*5²*12

  =300π cm³

  ≈ 942 cm³

Therefore, The volume of right circular cylinder is 942 cubic cm.

Determine if the values given for the variables are solutions to the following equations.
1. x = 4 and y = 8 for y = 3x - 4
2.m = 12 and n = 200 for n = 15m - 20
3.a = 5 and b = 48 for b = 8a + 8
4.g = 40 and h = 1000 for h = 25g + 300

Answers

Answer:

1. If x = 4 and y = 8, u = 3x - 4 would make sense because 3x, or 3 x 4 = 12

12 - 4 = 8 y = 8 (True)

2. m = 12 and n = 200 . n = 15m - 20 15 x 12 = 180 180 - 20 = 200 Would not make sense because 180 - 20 is 160 (False)

3. a = 5 and b = 48    b = 48 . 8a + 8 = 8 x 5 + 8 8 x 5 + 8= 48

(True)

4. G = 40 and h = 1000

H = 25g + 300

25g = 1000

1000+300= 1300, not 1000

(false)

Although the national medal standings are not recognized by the
International Olympic Committee (IOC), these standings are usually compiled for
each Olympics. Here are the final standings for the top ten teams for the 2000 Summer Olympics in Sydney. G represents gold medals won, S represents silver
medals won, B represents bronze medals won, and T represents total medals won. Country G S B T
United States 40 24 33 97
Russia 32 28 28 88
China 28 16 15 59
Australia 16 25 17 58
Germany 13 17 26 56
France 13 14 11 38
Italy 13 8 13 34
Cuba 11 11 7 29
Great Britain 11 10 7 28
Netherlands 12 9 4 25

1. If the top ten nations were randomly selected to march, one after another, into the stadium at the closing ceremonies, in how many ways could the nations have marched in?

2. Assume that the medals won by the Netherlands were won by twenty-five different athletes. These athletes are selected to compete in a contest for charity. Their names will then be listed on a plaque with the athletes who place first, second, and third listed before the others. How many different ways are there to list the top three athletes’ names on the plaque?

3. Assume that the gold medals won by Australia were won by sixteen different athletes. Following the Olympics, a parade of the Australian Olympic participants was held in Sydney. The gold medal winners marched at the head of the column, with four of the sixteen medalists carrying the Australian flag in the front row. If the arrangement of the four gold medal winners in the front row isn’t important, how many combinations of these four athletes are there?

Start by writing -3x-5=16. You can add 5 to both sides since the inverse operation of negative is adding positive. You will then get 16+5=21. Then you will get -3x=21. Divide by -3 on both sides. -3x/-3. 21/-3=-7 x=-7. Now check your answer -3(-7)=21-5=16. Checks out. Hopefully this helps!

After adding an 8-pound box with 6 identical boxes, the crate weighed 72 boxes

Answers

After adding 8 students to each of 6 same-sized teams, there were 72 students altogether.

After adding an 8-pound box of tennis rackets to a crate with 6 identical boxes of ping pong paddles, the crate weighed 72 pounds.

The first situation has all equal parts, since additions are made to each team. An equation that represents this situation is 6( x + 8 ) = 72, where x represents the original number of students on each team. Eight students were added to each group, there are 6 groups, and there are a total of 72 students.

In the second situation, there are 6 equal parts added to one other part. An equation that represents this situation is 6x + 8 = 72, where x represents the weight of a box of ping pong paddles, there are 6 boxes of ping pong paddles, there is an additional box that weighs 8 pounds, and the crate weighs 72 pounds altogether.

In the first situation, there were 6 equal groups, and 8 students added to each group. 6( x + 8 ) = 72.

In the second situation, there were 6 equal groups, but 8 more pounds in addition to that. 6x + 8 = 72.
