Answer:
300x^12/15x^10=300/15*x^12/x^10=20*x^2=20x^2
a^4/a^4=1
g^6/g^10=g^-4=1/g^4
so the answer is (20x^2)/g^4
Step-by-step explanation:
Answer:
2.15%
Step-by-step explanation:
If you were to get the z-score for both 500 and 550 and then get the probability of both those z-scores. After getting the probability you would subtract both probability and get your answer.
Z-score:
550-400/2=3
500-400/2=2
Probability:
3 (from the Z-table) is .9987
2 (from the Z-table) is .9772
.9987-.9772= .0215
.0215 as a percentage is 2.15%
Answer: 5(x-1)
Step-by-step explanation:
Answer:
see the explanation
Step-by-step explanation:
Let
x ---> kilograms of cement needed
y ----> kilograms of sand needed
z ----> kilograms of gravel needed
we know that
----> 

Divide 480 by 8
----> scale factor
Multiply the scale factor by the ratio 
<em>Find out the kilograms of cement needed</em>

<em>Find out the kilograms of sand needed</em>

<em>Find out the kilograms of gravel needed</em>

Answer:
$530
Step-by-step explanation:
500*0.06=30
500+30=530
Therefore, the answer is $530
