Answer:
31.4
Step-by-step explanation:
So a really easy way to solve this is as goes
--> 3.14 x (20 x 1/2)
--> 3.14 x (10)
Now multipling by 10 is just moving the deciaml place one spot to the right
=> thus, we get 31.4
Hope this helps!
Answer:
We use log to solve only those equations in which we have our variables in power form.
Step-by-step explanation:
Given : Margee thinks she can use logs to solve
, since logs seem to make exponents disappear but Margee is wrong
We have to explain the difference between equations like
and
We use log to solve only those equations in which we have our variables in power form.
Out of given equation only
has x in power form so we can apply log for solving the equation as,

While solving other equation ,
, we can directly take 8 root both side, 
Thus, We use log to solve only those equations in which we have our variables in power form.
Answer:
Step-by-step explanation:
point-slope equation of the line: y+1 = -(x-3)
rearrange to solve for y:
y+1 = -x+3
y = -x + 2 slope-intercept form
1. To convert the fraction to a decimal, divide the numerator by the denominator
6230/14
2. Calculate it
445
The answer would be 2.16.
This is because the two negatives would cancel each other out when multiplying. This would basically make the question

.
Now 3.3 is definitely not less than 2.4, so the answer would be 2.16
