The areas of two circles are 36(pi) and 64(pi). What is hte ratio of the diameters? of the circumferences?

Answers

Answer 1

Answer: $A_1=36\pi\ \ \ \Rightarrow\ \ \ \pi r ^2=36\pi\ \ \ \Rightarrow\ \ \ r^2=36\ \ \Rightarrow\ \ r=6\n \nA_2=64\pi\ \ \ \Rightarrow\ \ \ \pi R ^2=64\pi\ \ \Rightarrow\ \ R^2=64\ \ \ \Rightarrow\ \ R=8 \n\n\n (2r)/(2R) = (r)/(R) =(6)/(8)= (3)/(4)\ \ \ \ \ \ \ \ and\ \ \ \ \ \ \ \ (2\pi r)/(2\pi R) =(r)/(R) = (3)/(4)$

Answer 2

Answer: 2,304 because if you multiply 36 x 64 is 2,304 if not multiply 2,304 x 36 x 64 and then divide the answer by 36 & 64 the it should be 2,304

How to solve this equation
8(4-x)= 7x+2

Answers

8 ( 4 - x ) = 7x + 2
32 - 8x = 7x + 2
      -7x     -7x
--------------------------
32 - 15x = 2
-32           -32
----------------------------
-15x = -30
/-15      /-15

x = 2.

8(4-x)=7x+2
32-8x=7x+2
-8x-7x=2-32
-15x=-30
x=-30:(-15)
x=2
answer:x= 2

How many liters of water should be added to 18 liters of a 14% bleach solution so that the remaining solution contains only 10% bleach?

Answers

How many liters of water should be added to 18 liters of a 14% bleach solution so that the remaining solution contains only 10% bleach?
:
Let w = amt of water required to make a 10% solution
:
.14(18) = .10(w+18)

2.52 = .1w + 1.8
2.52 - 1.8 = .1w
.72 = .1w
multiply both sides by 10
7.2 = w
:
7.2 liters of water added
