I Need Help Because I Dont Understand It

Answers

Answer 1

Answer:

6,371.15

Step-by-step explanation:

3.14 times 13^2 times 12

Answer 2

Answer:

Volume equals pi times radius to the power of 2 times height

that will be pi times 13^2 times 12= 6,367.92

radius is the 13 and you have to put it to the power of 2 and multiply it by 3.14 which is pi and multiply it by 12 and the answer is 6,367.92

The graph for the equation Y= 2X+4 is shown below.
If another equation is graphed so that the system has one solution, which equation could that be?
Oy= 2x-4
Oy=2(x+ 2)
Oy=2(x-4)
Oy=x+4

Answers

To have only one solution the two lines must have different slopes, then the correct option is:

y = x + 4.

Which equation could it be?

We want our system to have exactly one solution, so the two lines must have different slopes.

The already graphed line s:

y = 2x + 4

Notice that the slope is 2, then we need to select the option with an slope different than 2, which is the last option:

y = x + 4

If we graph that line, the system will have only one solution.

Answer:

x = 20

p = 144

y = 144

Step-by-step explanation:

Vertically opposite angles are equal.

2x - 4 = 96 - 3x

2x + 3x -4 = 96

    5x - 4 = 96

         5x = 96+4

         5x = 100

           x = 100/5

           x = 20

2x - 4 = 2*20 - 4 = 80 - 4

         = 36

p + (2x - 4) = 180  {linear pair}

p + 36 = 180

        p = 180 - 36

        p = 144

y =  p        {vertically opposite angles}

y = 144

Answer:x = -0.1290322581

Step-by-step explanation:

Simplifying

9x + -4(1 + 10x) = 0

9x + (1 * -4 + 10x * -4) = 0

9x + (-4 + -40x) = 0

Reorder the terms:

-4 + 9x + -40x = 0

Combine like terms: 9x + -40x = -31x

-4 + -31x = 0

Solving

-4 + -31x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + -31x = 0 + 4

Combine like terms: -4 + 4 = 0

0 + -31x = 0 + 4

-31x = 0 + 4

Combine like terms: 0 + 4 = 4

-31x = 4

Divide each side by '-31'.

x = -0.1290322581

8. Which is not equivalent to 3p-2=6p+4?Explain.
a.) 3p=6p+6

b.) 3p=6

c.) -6=3p

d.)-3p-2=4

Answers

Answer:

b.) 3p=6 is not equivalent

Step-by-step explanation:

If you solve and do the same thing on both sides you will get every other solution except b.

Answer:

The correct answer is b) 3p = 6

Step-by-step explanation:

First, we need to find p:

3p - 2 = 6p + 4

-2 = 3p + 4

-6 = 3p

-2 = p

Now, we just need to plug p's value into each question:

a) 3p = 6p + 6

3(-2) = 6(-2) + 6

-6 = -12 + 6

-6 = -6

Since -6 = -6, a is not the correct answer.

b) 3p = 6

3(-2) = 6

-6 = 6

Since -6 ≠ 6, b is the correct answer.

c) -6 = 3p

-6 = 3(-2)

-6 = -6

Since -6 = -6, c is not the correct answer.

d) -3p - 2 = 4

-3(-2) - 2 = 4

6 - 2 = 4

4 = 4

Since 4 = 4, d is not the correct answer.

Therefore, b is the correct answer.
