Answer:

I think it will be D, because you will be decreasing 0.25x and increasing 0.75x, you will add 0.25x to -0.25x to get rid of 0.25x. Then you will need to do the same thing to the other side. You will add 0.25x to 0.75x so you will be increasing 0.75 since you will be adding to it.

Step-by-step explanation:

X – 0.25x = 0.75x

X-0.25x+0.25x=0.75x+0.25x

X= 1.00x

All you need to do is add 0.25x to both -0.25x and positive 0.75x. That way it will be equal.

So, I believe it will be D

$\sf {a}^{2} = {13}^{2} - {5}^{2}$

Formula :

Base²= Hypotenuse² - Perpendicular ²

$\\ \\$

$\hookrightarrow\sf {a}^{2} = {13}^{2} - {5}^{2}$

$\\ \\$

$\hookrightarrow\sf {a}^{2} =169 - 25$

$\\ \\$

$\hookrightarrow\sf {a}^{2} =144$

$\\ \\$

$\hookrightarrow\sf {a} = \sqrt{144}$

$\\ \\$

$\hookrightarrow\sf {a} = \sqrt{12 \times 12}$

$\\ \\$

$\hookrightarrow\sf {a} = 12$

Remember the a² in formula has nothing to do with the a we have to find. :)

Hello everyone I need help with this worksheet it's ten problems answer the ones you know for me please it's homework.

Fed [463]

Answer:

1. Slope = -4/5

2. Slope = 2/3

3. Slope = 0

4. Slope = 3/-4

5. Slope = 7/-12

6. Slope = 1/2

7. Slope = -2/0 --> Undefined

8. Slope = 3/-2

9. Slope = 5/-4

10. Slope = 4/3

Step-by-step explanation:

Ok so I'm assuming that you want the slope for all the two points. Basically, the formula for slope is rise/run, or y2-y1/x2-x1. Solve using that. For example, for number 1, it would be:

10-2/1-11 = 8/-10 = -4/5

A circle has a circumference of 10 pi what is the length of the radius

Talja [164]

------------------------------------------------------
Formula
------------------------------------------------------
Circumference = πD

------------------------------------------------------
Find Diameter
------------------------------------------------------
10π = πD
D = 10 ← divide by π on both sides

------------------------------------------------------
Find Radius
------------------------------------------------------
Radius = Diameter ÷ 2
Radius = 10 ÷ 2
Radius = 5

------------------------------------------------------
Answer: Radius = 5 units
------------------------------------------------------
