Answer:
Step-by-step explanation:
The equation is:
√b+20 - √b = 5
The first step is we will add √b to both sides:
√b+20 -√b +√b = 5 +√b
√b+20 = 5+√b
Now take square at both sides:
(√b+20)^2 = (5+√b)^2
b+20 = 25+10√b+b
Now combine the like terms:
b+20-25-b=10√b
-5 = 10√b
Divide both the terms by 10
-5/10 = 10√b/10
-1/2=√b
Take square at both sides:
(-1/2)^2 = (√b)^2
1/4 = b
So in this type of question we add radical terms to both sides and square both sides twice....
Answer:
20%
Step-by-step explanation:
To find this, set up a ratio of percent over 100 equals is over of. Is being 32 and of being 160.
= 
Then, cross multiply. Multiply 32 by 100 before dividing by 160 in order to get the final answer of 20%.
32 x 100 = 3200
3200/160 = 20
Hope this helps!
It would be greater
48.51 > 48
Answer:
-1/8
Step-by-step explanation:
When slopes are perpendicular that means it's completely opposite.
The opposite of 8 is 1/8
But 8 is positive that means we have to make the pereldicular slope negative
Therefore your answer is -1/8
