Answer:
The final result is 1
Step-by-step explanation:
Remember the following:
And that x^0= 1
We have: 8^7 / 8^7= 8 ^ (7-7)=8^0=1
x*-8 would be -8x
then you would divide -8 by both sides
should get a decimal as your answer I believe
Answer:
A score of 117 is needed, which Is not possible since the test is over 100.
Step-by-step explanation:
The other 3 scores are 85, 94,84 . Let's x be the 4th score he must score.
Therefore ( 85 + 94 + 84 + X)/4 =95
Then 263+X /4 =95
Cross mutiplying 4*95=263+X
Therefore X= 380-263
X= 117 which is not possible since the test score is over 100.
Answer:
b = -125/9
Step-by-step explanation:
1 + log5 ( -9b) = 4
Subtract 1 from each side
1 -1+ log5 ( -9b) = 4-1
log5 ( -9b) = 3
Raise each side to the base 5
5^ log5 ( -9b) = 5^3
This will cancel the log5
-9b = 125
Divide each side by 9
-9b/-9 = 125/-9
b = -125/9
Answer:
56 cubic meter
Step-by-step explanation:
Volume of a pyramid: V=(lwh)/3
So then 7*3*8/3= 7*8 =
56 cubic meter
