Answer:
1/p^1
Step-by-step explanation:
5p^2/5p^3
- cancel the fives
2. subtract denominator exponent from numerator exponent
- p^-1
- (you can't have negative exponents so you have to move the negative exponent coefficient to the denominator to make it possitive)
3. 1/p^1
OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.
The correct answer is D) 192.
Hope this helps

Answer:
59
Step-by-step explanation:
4^2 +5*3^2 -4^2 / 2^3
order of operations says to do first parenthesis, exponents, then division and multiplication
first the exponents
4^2 = 16
3^2= 9
4^2=16
2^3=8
16+ 5*9-16/8
then multiply 5*9
=16+ 45 -16/8
simplify the fraction
=16+ 45 -2
add them
=59
i hope this helps
