Answer:
4/15 is the answer my guy
Step-by-step explanation:
5/3 x 4/25= 20/75 simplified is 4/15
A.) b = 0.7a
d) 1a = b
These two equation shows the direct variation. with the coefficient of a as the constant of variation.
y = kx ; where k is the constant of variation. y directly varies with x at the rate of k.
b = 0.7a where b represents y ; a represents x; and 0.7 represents k.
1a = b where b represents y ; a represents x ; and 1 represents k.
Answer:
7
when dividing exponents with the same base, you subtract them. so, 11-7 = 4
Hey there!
To find percent error, we find the difference between the prediction and the actual value. We take that difference, divide it by the prediction, and multiply it by 100.
So let's find the difference.
42 - 30 = 12
Divide the difference, which is 12, by 30.
12 ÷ 30 = 0.4
Multiply this by 100 to get the percent.
0.4 x 100 = 40
The percent error is 40%.
Hope this helps!
