Answer:
Step-by-step explanation:
Use vertical angles to help solve the problem. Angles that are across from each other are congruent. For exmaple, <2 = 85 degrees because the angle across from it is 85 degrees. I assume angle 1 is 95 degrees, so angle 3 would also be 95 degrees.
Hey there! I'm happy to help!
Let's call our fraction x.
x=3.777......
We want to get rid of the repeating stuff. If we multiply our fraction by 10, we get 10x=37.7777.
We see that if we subtract x from 10x, the repeating numbers will be cancelled out. Let's do this.
10x=37.7777
-
x=3.77777
=
9x=34
We divide both sides by 9.
x=34/9=3 7/9.
Have a wonderful day! :D

Let us consider , there are 30 boys and 40 girls in a school. So, the ratio of number of boys to number of girls = and read as 3 is to 4. We can say , the ratio compares two of more quantities of same unit. Until two quantities have same units , it is meaningless to compare by ratio. So, to find the ratio of two quantities , it is necessary to express them in same unit or of same kind. Since , they are in division form. So ,ratio is unit less quantity. Thus , the ratio is a comparison of two quantities of the same kind in division which doesn't have any units. For example : is a ratio and is read as ' a is to b ' in which ' a : is antecedent and ' b ' is called consequent.

Number of CDs Kitts sold last week = x = 84
Number of CDs she sold this week = y = 26
Hope this helps :DD !!
Volume of sphere = 4/3 x pi x r^3
904.32 = 4/3 x pi x r^3
Divide both sides by 4/3
678.4 = pi x r^3
Divide both sides by pi:
216 = r^3
Take the cubic root of both sides
R = 6
