Answer:
12:1/2(3)
Step-by-step explanation: no problem homie
Enrolement increased by 30% that means last year=100%
incease of 30%=30+100=130% now
now=182
percent means parts out of 100 so
130%=130/100=13/10
182=13/10 of x (x represents the number last year)
of means multipy so
182=13/10 times x
multiply both sides by 10/13 to clear fraction
182 times 10/13=x=140
140 students last year
Answer:
12 meters
Step-by-step explanation:
The area of a parallelogram can be found using:
a=bh
We know that the base is 7 meters, and the area is 84 square meters. Therefore, we can substitute 7 in for b, and 84 in for a.
84=7h
We want to find the height. To do this, we have to get h by itself. Since h is being multiplied by 7, divide both sides by 7.
84/7=7h/7
12=h
So, the height is 12 meters
Answer:
A.16b^4/81
step-by-step explanation:
(2b/3)^4
= (2b)^4/3^4
= (2^4×b^4)/3^4
=16b^4/81
(as 16 and 81 cant simplify each other)
