A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 cm and the bicycle wheel makes 3 full rotat

iragen [17]

Answer:

565.2cm

Step-by-step explanation:

Since we need to find out the circumference because the radius of the tire is 30cm. We take 30cm times 2. Which we get 60cm, then we take 60cm times 3.14 to get the circumference of 188.4cm. Then we take 188.4cm times 3 full rotations to get 565.2cm.

Logan is buying equipment for the football team and the baseball team. He spends $40 on football uniforms, and he plans on purch

aleksandr82 [10.1K]

Answer:

The coordinate pair that represents this solution is (20 , 240)

Explanation:

We are given that:

1- Equation that represents amount paid on football team based on number of purchased footballs is:

y = 40 + 10x

2- Equation that represents amount paid on baseball team based on number of purchased baseballs is:

y = 200 + 2x

Now, Logan wants to spend the same amount of money on both teams. This means that the y value in both equations should be equal

He also wants to buy the same number of balls for the two teams. This means that the x value in both equations should also be equal.

Therefore, we would be getting the point of intersection between the two equations.

To do this, we will start by equating the two equations and solving for x as follows:

40 + 10x = 200 + 2x

10x - 2x = 200 - 40

8x = 160

x = 20

Then, we will use the x to substitute in any of the two equations:

Substituting in the first equation:

y = 40 + 10x = 40 + 10(20) = 240

Substituting in the second equation (as a check):

y = 200 + 2x = 200 + 2(20) = 240

Based on the above calculations:

If Logan bought 20 balls for each team, he will be spending $240 on each

Solution set is (20, 240)

Note: the graphical solution is attached.

Hope this helps :)

Celestial object A is composed of 92.1 percent hydrogen and 7.8 percent helium while celestial object B is made up of ice, froze

RSB [31]

Answer: celestial body A is most probably a star.

Step-by-step explanation:

The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass the composition of the sun is about 75 percent hydrogen and 25 percent helium. The sun is a star in our solar system and stars like the sun need a lot hydrogen for generating their enermous energy from fission of hydrogen atoms into helium atom.
