What is the original number if 9/10 of the number is 90?
coldgirl [10]
It would be 100. If you divide 100/10, you get 10, multiply that by 9 and you’d get 90.

What is the equation of the circle with center (1, 1) that passes through the point (−3, 4)?
Alex_Xolod [135]

Answer:  (x - 1)² + (y - 1)² = 25

<u>Step-by-step explanation:</u>

The formula for a circle is     (x - h)² + (y - k)² = r²     where

  • (h, k) is the center
  • r is the radius

Typically, you are given the center and the radius.  In this problem, you are given (x, y) so you must plug that into the equation to find r².

Given: (x, y) = (-3, 4)   and   (h, k) = (1, 1)

                       (-3 - 1)² + (4 - 1)² = r²

                         (-4)²    +   (3)²   = r²

                          16      +    9     = r²

                                  25         = r²

Next, input (h, k) and r² into the equation

                  (x - 1)² + (y - 1)² = 25

Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Oliver spent 4 an
LUCKY_DIMON [66]

The time taken by Oliver to complete the work is less than or equal to twice the work done by Karissa.

Option B shows the correct equation of inequality to write the time taken to complete the work.

<h3>What is inequality?</h3>

Inequality can be defined as a relation that makes a non-equal comparison between two numbers or other mathematical expressions.

Given that Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Also, the time taken to complete the project is,

Oliver = 4 and one-fourth hours

Karissa = K hours

As per the given condition, the work done by Oliver should not be more than twice the work done by Karissa. It can be equal or less. So we can write this in equation form as,

Oliver \leq 2 Karissa

4\dfrac {1}{4} \leq 2K

Hence Option B shows the correct equation of inequality to write the time taken to complete the work.

To know more about inequality, follow the link given below.
