B. 67/2 and (VG)
C. 52/3 and (15)3
O D. 75/7 and (77)5
Answers
Given:
The pair of expressions in the options.
To find:
The pairs which show a pair of equivalent expressions.
Solution:
Property of exponent:
[tex](\sqrt[n]{x})^m=x^{\frac{m}{n}}[/tex]
In option A,
[tex](\sqrt[4]{81})^5=81^{\frac{5}{4}}[/tex]
So, option A is correct.
In option B,
[tex]6^{\frac{7}{2}}=(\sqrt[2]{6})^7[/tex]
[tex]6^{\frac{7}{2}}=(\sqrt{6})^7[/tex]
So, option B is correct.
In option C,
[tex]5^{\frac{2}{3}}=(\sqrt[3]{5})^2[/tex]
[tex]5^{\frac{2}{3}}\neq (\sqrt{5})^3[/tex]
So, option C is incorrect.
In option D,
[tex]7^{\frac{5}{7}}=(\sqrt[7]{7})^5[/tex]
[tex]7^{\frac{5}{7}}\neq (\sqrt{7})^5[/tex]
So, option D is incorrect.

You are planning a trip of 900 miles. Your car gets about 21 mpg. Gasoline costs $1.59 per gallon. How much should you budget for gas on this trip? Round answer to the nearest ten (10)
Answers
Answer:
$64.3
Step-by-step explanation:
Given the following
Total distance = 900miles
Rate per gallon = 21miles per gallon
rate = distance/time
Get the number of gallons used;
Number of gallons used = 900/21
Number of gallons = 42.857gallons
If coost of 1 gallon is $1.50
42.857gallons will cost 42.857 * 1.50
42.857gallons will cost $64.3
Hence he should budget $64.3 for the trip
I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am positive and prime. What number am i?
Answers
Answer:
2, 3, 5, 7, 11, 17, 19, 23
Step-by-step explanation:
The segment between - 15 and 25 has 40 numbers given by
25 - -15
= 25 + 15
= 40
Divided into 4 segments, each would contain 10 numbers such that the
1st segment is from -15 to -5 (which is -15 + 10)
2nd segment is from -5 to 5 (which is -5 + 10)
3rd segment is from 5 to 15 (which is 5 + 10)
4th segment is from 15 to 25 (which is 15 + 10)
Given that the unknown number is prime and positive this may be
2 or 3 or 5 from the 2nd segment
7 or 11 from the third segment
17 or 19 or 23 from the 4th segment

Find the simple interest and amount when principal = Rs. 6000, rate = 6% per annum and time = 4 years
Answers
Given:
Principal = Rs. 6000
Rate of simple interest = 6% per annum.
Time = 4 years
To find:
The simple interest and amount.
Solution:
Formula for simple interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest and t is the number of years.
Putting P=6000, r=6 and t=4, we get
[tex]I=\dfrac{6000\times 6\times 4}{100}[/tex]
[tex]I=60\times 6\times 4[/tex]
[tex]I=1440[/tex]
Now,
[tex]Amount=Principal+Interest[/tex]
[tex]Amount=6000+1440[/tex]
[tex]Amount=7440[/tex]
Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.

what is 11/4-3/8= what is it or get me the right answer
Answers
Answer:
2 3/8 is the answer
Step-by-step explanation:
11/4 - 3/8
We will find the LCM of 4 and 8, which is 8.
We will do 11/4*8, which 8/4 = 2 and 2*11 = 22
Then we will do 3/8*8 = 8/8 = 1 = 3*1 = 3
So the answer will be 22-3 = 19
8 = 8

tell me if the statement below is sometimes, always, or never true. justify your reasoning, (the Expressions x - 3 + y -3 represent the same value.)
Answers
Answer:
Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true
Step-by-step explanation:
We are given two expressions: x -3 and y - 3
Here x and y are two different variables.
These expressions are equal, when the value of x and the value of y are equal.
x - 3 = y -3 if x = y.
Therefore, the two expressions have the same value in sometimes.
That is, when x = y, then the value of two expressions are the same.
Example.
If x = 2 and y = 2, then
x - 3 = y - 3
2 - 3 = 2 - 3
-1 = -1
If they have different values, for x = 2 and y = 3
x - 3 = y - 3
2 - 3 = 3 -3
-1 = 0
Which is not true.
Therefore, the answer is sometimes.

Answer: 34.5
Step-by-step explanation:
First, write out all of the numbers from least to greatest.
which is (18,20,26,34,34,35,38,40,42,45)
Second, choose the number in the middle of the set of numbers you wrote out from least to greatest. (There are TWO numbers in this case, which are 34 and 35)
Lastly, since there are two numbers you add them both together and then divide by 2. (34+35=69 , 69 divided by 2 = 34.5)
