No. You can actually solve this question without doing any math. Her only score that is above a 90 is 93, so it will be brought down lower than a 90 very easily by the 77 and the 82.
1/5 is the simplest form of the fraction
142 meters
with all the mathy stuff i did the answer was 142 meters
To find the circumference of a circle the formula is pi times diameter. The radius is half the diameter, so you have to find the diameter by multiplying 2.75 by 2. you get 5.5. Pi is around 3.14, so 5.5 times 3.14 is 17.27. Because you have to convert feet to yards, divide 17.27 by 3 (there are 3 feet in a yard). You get around 5.76. Because if Alexa bought only five meters of lace, she will run short, she needs to buy 6 meters of lace.
Answer:
1) 512
2) 27
3) 216
4) 8
5) 343
6) 729
Step-by-step explanation:
1)(8^4)^3/4 = 8^3 [using the power of power rule]
=8*8*8
= 512
2) The second can be written as (81)^3/4
81 = 3^4
Therefore, (3^4)^3/4 = 3^3
= 27
3) 1296 = 6^4
Therefore, (1296)^3/4 = (6^4)^3/4
= 6^3
= 216
4) 16^3/4 = (2^4)^3/4
= 2^3
= 8
5) 2401 = 7^4
The expression can be written as (2401)^3/4
= (7^4)^3/4
= 7^3
= 343
6) 6561 = 9^4
The given expression can be written as (6561)^3/4
= (9^4)^3/4
= 9^3
= 729
Hope you will understand the concept.
Thank you.
