Find the value of y in the equation attached to this question
dlinn [17]

Answer:

y = 4

Step-by-step explanation:

1) Simplify 3^5 to 243.

{9}^{y}=\frac{243\times {9}^{6}}{{27}^{3}}

2) Simplify {9}^{6} to 531441.

{9}^{y}=\frac{243\times 531441}{{27}^{3}}

3)  Simplify  243\times 531441 to  129140163.

{9}^{y}=\frac{129140163}{{27}^{3}}

4) Simplify  {27}^{3}  to  19683.

{9}^{y}=\frac{129140163}{19683}

5) Simplify  \frac{129140163}{19683} to 6561.

{9}^{y}=6561

6) Convert both sides to the same base.

9^y=9^4

7)  Cancel the base of 9 on both sides.

y=4

A circular tabletop has a circumference of 94.2 inches. What is its approximate area?
MrRa [10]

Answer:

1st choice : 706.5 square inches

Step-by-step explanation:

circumference is pi times diameter

divide 94.2 by pi to get diameter = 29.9847912785

diameter 29.9847912785 divided by 2 is

14.9923956393 which is the radius

area is pi times radius times radius again

pi times 14.9923956393 times 14.9923956393 =

706.141834613
