The spinner is divided into eight equal sections marked with eight different colors what situation could be represented by the s
meriva
I believe the answer you looking for is Probability.

This means that if someone spinned that wheel, they have a probability of getting the color they need.

For instance,
Let's say this wheel had the colors red, orange, yellow, green, blue, indigo, purple, and pink.
If I wanted the color red on the spinner, I have a 1/8 chance to spin the color red. I have a 7/8 chance of NOT spinning red. However, let's say the wheel had 4 colors that were pink and 4 colors that were blue. If I wanted to spin the color pink, I would have a 4/8 chance OF spinning it and a 4/8 chance of NOT spinning it. 4/8 is also equivilant to 1/2.

I hope this helps you understand!!
Please mark brainliest!!
Thanks!!

A coin bank contains only quarters and dimes. The total value of the coins in the bank is $8.80. If the dimes were quarters and
masha68 [24]

Answer:

  • 18 dimes

Step-by-step explanation:

Let the number of dimes be d and quarters be q

<u>The value is $8.80 = 880¢, so:</u>

  • 10d + 25q = 880 ⇒ 2d + 5q = 176

<u>If the dimes were quarters and the quarters were dimes, the coins' total value would be $7.30 or 730¢</u>

  • 25d + 10q = 730 ⇒ 5d + 2q = 146

<u>Now we have 2 equations. Solving the system by elimination, subtract 5 times the second equation from twice the first equation:</u>

  • 2(2d + 5q) - 5(5d + 2q) = 2(176) - 5(146)
  • 4d - 25d = -378
  • -21d = -378
  • d = -378/-21
  • d = 18

An ant can travel at a constant speed of 980 inches every 5 minutes. At this rate, how far can the ant travel in 7 minutes?
Ratling [72]
I think that answer is 1375


Explanation:

980 divided by 5= 196

196x5=980 so

196x7= 1375

Since the the unit rate was 196.


Might be wrong though

<span>"five plus" means addition, so we have 5 +

</span><span>"the quotient of r and 14" is the division result, so sign / must be present: 14/r
</span>
Therefore "five plus the quotient of r and 14" is 5 + 14/r
