Answer:

200 marbles are blue only if there are 600 marbles in total. If there are more than 600, you calculate by dividing the total number of marbles by three.

What is the center of the circle that has a diameter whose endpoints are (9, 7) and (-3, -5)?
emmasim [6.3K]

Answer: OPTION B.

Step-by-step explanation:

Given the endpoints of the diameter of the circle, we  need to find the midpoint, which is the center of the circle.

The following formula is used to calculate the Midpoint:

M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

Given the endpoints of the diameter of the circle:

(9, 7)\ and\ (-3, -5)

We can identify that:

x_1=9\\x_2=-3\\y_1=7\\y_2=-5

Then, we can substitute these values into the formula:

M=(\frac{9+(-3)}{2},\frac{7+(-5)}{2})\\\\M=(3,1)

Therefore, the center of the circle is: (3,1)

A car dealership increased the price of a certain car by 13%. The original price was $47400 what is the new price?
garik1379 [7]

Answer:

Step-by-step explanation:

To get the new price of the car multiply the original price by the percent increase in decimal form  +1. 11% in decimal form is 0.11 = 11/100. Add one to this and you get 1.11 = 1 + 0.11. So now multiply $49,800 * 1.11 = $55,278. If the problem had said they decreased the price by 11% you would use 1 - 0.11 = 0.89 because 89% is 11% less than 100%.

hope that helps my man

5 rational and irrational numbers in decimal form
alexira [117]

Answer:

A rational number is a number that can be expressed as a fraction (ratio). This includes whole numbers, square roots that can be solved evenly, negatives, decimals, and repeating decimals that can be solved with a fraction.

  1. \frac{1}{2}   ↔  .5
  2. 5  ↔ 5.0
  3. \sqrt{4} ↔ 2.0
  4. -13  ↔  -13.0
  5. 0.38462... (\frac{5}{13})

An irrational number is a number that is NOT rational. It's the complete opposite!

  1. π  ↔  3.14159
  2. .13133133...
  3. \frac{\sqrt{3} }{2}   ↔  0.86603...
  4. -\sqrt{5}  ↔  -2.23607...
  5. \sqrt{5}   ↔   2.23607...

Hope this helps!!!
