Write 7 as a fraction with the 9 in the denominator

Answers

Answer 1
Answer: so 7=7/1
to put a 9 in the bottom and make the fraction stay the same, multiply it by 1
or 9/9 since 9/9=1 so
7/1 times 9/9=(7 times 9)/(1 times 9)=63/9
answe ris 63/9
Answer 2
Answer: 63/9 would be the answer because 63 divided by 9 would be equivalent to 7/1 or 7.

Answers

so first find the volume of each then subtract

volume=4/3 times pi times r^3

rasius of smaller=3
4/3 times pi times 3^3
4/3 times pi timer 27
4/3 times 27 times pi
36 times pi
aprox pi=3.14
36 times 3.14
113.04=smaller

volume of smaller
4/3 times 3.14 times 4.5^3
4/3 times 3.14 times 91.125
381.51

subtract
381.51-113.04=268.47

the volume is 268..47 cm^3

8:4 6:4 8:2 6:3 biggest ratio

Answers

Easy, make the ratios as a decimal. 8:4=2, 6:4=1.5, 8:2=4, and 6:3=2. Now, we have 2, 1.5, and 4, and 2. We can eliminate 8:4 and 6:3 since they are the same ratios, 1.5 equals 1.50, 4=4. Ask your self. Is 1.50 greater than 4? Well your answer is no. 4 is greater than 1.50. So, the biggest ratio is 8:2
8:2 is the biggest ratio, because if you reduce each ratio to the smallest ratio 4:1 is the biggest. 8:4 = 2:1... 6:4 = 3:2...  8:2 = 4:1... 6:3= 2:1...

How do you make 7,5,6,and 3 equal 75 without parentheses

Answers

Answer:

(6 * 5)/(3) * 7 +5

Step-by-step explanation:

To express this problem using 7, 5, 6 and 3 without parenthesis, we have to use at least one number twice, because suing parenthesis is so much easier to express the result. So, the operations would be:

(6 * 5)/(3) * 7 +5=(30)/(3)* 7 +5\n 10* 7 +5=70+5=75

Therefore, the expression would be:

(6 * 5)/(3) * 7 +5

when you roll two number cubes, what are the odds, in simplest form, in favor of getting two number less than 4 ?

Answers

The odds of getting less than 4 on one cube is 3/6 so 1/2 and if you roll two cubes the odds are 1/2 times 1/2 so the odds of getting two numbers less than 4 is 9/36 or in simplest form, 1/4

First, it depends on the answer.  If you are on the same quiz, the options should be

A) 1:3

B) 3:1

C) 1:4

D) 4:1

The answer is C or 1:4.  

Because it is in it's favor, the "1" would go first, standing as the numbers before "4" on a cube.  The probability in fraction form would be 3/6, or simplified to 1/2.  P ( >3, > 3) = P ( >3) = 1/2 x 1/2 = 1/4.  This leaves 1:4 being you're answer.
