What is the midpoint of BC?

Mathematics
2 answers:
kherson [118]4 years ago
6 0

To find the midpoint, add the two x values together and divide by 2, and then do the same with the Y values.

-3 + 3 = 0

0 / 2 = 0, the X value is 0

-1 + 3 = 2

2/2 = 1, the Y value is 1

The midpoint would be (0,1)

Answer:

The answer to your question is (0, 1)

Step-by-step explanation:

Data

B (3, -1)

C (-3, 3)

Formula

Xm = \frac{x1 + x2}{2}

Ym = \frac{y1 + y2}{2}

Substitution and simplification

Xm = \frac{3 - 3}{2}

Xm = \frac{0}{2}

      Xm = 0

Ym = \frac{-1 + 3}{2}

Ym = \frac{2}{2}

      Ym = 1

Result

           (0, 1)

Solve 3x/2 - 7=x/4 - 2 i know the answer is 4 but how do i solve this
Digiron [165]
First, multiply by 4 on both sides to eliminate the denominator, and you get...
6x-28 =x-8
Subtract x on both sides and add 28...
5x=20
Divide to isolate the variable...
x=4
Hope this helps

How to find the diameter of a circle when given the circumference?
andre [41]
The formula for the circumference of a circle, c=πd or c=2πr, can also be used to find the diameter or radius of a circle.

Let's look at an example.

A circle has a circumference of 20.72 m. What is its diameter?

First, write down the formula.

c=πd

Next, fill in the values that you know.

20.72 m=3.14 d

Then, divide both sides of the equation by 3.14

6.6=d

The answer is the diameter is 6.6 meters.

A retired woman has $280,000 to invest. She has chosen one relatively safe investment fund that has an annual yield of 9% and an
ASHA 777 [7]

Answer:

9% fund: $ 210,000

13% fund: $70,000

Step-by-step explanation:

As she wants to have a $28,000 annual return for her $280,000 investment, she is expecting a return rate of 10%:

r=\dfrac{R}{C}=\dfrac{28,000}{280,000}=0.10

If we call x the proportion of the capital in the 9% fund, then (1-x) is the proportion of the capital in the 13% fund,and the return of the combination has to be the expected return of 10%:

0.09x+0.13(1-x)=0.10\\\\0.09x+0.13-0.13x=0.10\\\\-0.04x=0.10-0.13=-0.03\\\\x=\dfrac{0.03}{0.04}=0.75

Then, we know that 75% of the capital should be invested in the 9% fund and 25% in the 13% fund.

This correspond to a capital of:

9% fund: 0.75*$280,000 = $ 210,000

13% fund: 0.25*$280,000 = $70,000
