y=15

5y-20=2y+25 move terms

5y-2y = 25+20 calculate like terms

3y=45 divide both sides by 3

You would make the equation 5y-20=2y+25 and then solve

You would add both sides by 20

5y=2y+45

Then you would add both sides by -2y

3y=45

finally you will multiply both sides by 1/3 and get 15 as Y

y=15

Circle O has a circumference of approximately 28.3 cm. What is the approximate length of the radius, r?

Scrat [10]

Answer:

4.5 cm.

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

$\text{Circumference of a circle}=2\pi r$

Upon substituting the measure of circumference in above formula we will get,

$28.3=2\pi r$

$r=\frac{28.3}{2\pi}$

$r=4.504084889500638\approx 4.5$

Therefore, the radius of circle O is 4.5 cm.

Answer:

Look at the image.

Step-by-step explanation:

If 12 is 24%, then half of the percent is the actual number.

36% = 18

24% = 12

18% = 9

22% = 11

18 + 12 + 9 + 11 = 50

Answer:

please last option

using 45 degree as reference angle

using tan relation

Tan45=perpendicular /base

1 = x\6

x = 6

now using right angled triangle relation

H²=p²+b²

then h²= 6²+6²

H = √36+36

H =6√2

therefore y=6√2
