Answer:
x = 13/8
Step-by-step explanation:
sqrt(8x-4) +8 = 11
Subtract 8 from each side
sqrt(8x-4) +8-8 = 11-8
sqrt(8x-4) =3
Square each side
(sqrt(8x-4))^2 =3^2
8x-4 = 9
Add 4 to each side
8x-4+4 = 9+4
8x = 13
Divide by 8
8x/8 = 13/8
x = 13/8
You have to subtract 8 from the left and then 8 from the right. If you do that then you'll have 5x=15.
Then you divide "x" by 5 and 15 by 5.
X=3
Answer:
82.72m
Step-by-step explanation:
Volume = πr2h
= 3.142*7*7*14
= 2,155.41m³
Now that we hav the volume of earth, we go on to find the raduis of the spread
2155.41m³ = 3.142*r²*0.4
2155.41m³ = 1.26r²
r² = 1,710.64
r = 41.36m
Width = diameter = 2r = 82.72m
The percentage value of puppies weighing over 6 pounds is 25%
What is Percentage?
Percentage is a relative number that represents the hundredth part of any quantity. One percent (symbolised 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount.
Solution:
Given that there are 12 puppies in total and 3 of them weighted above 6 pounds
To calculate the percentage we need to divide 3 by 12 and then multiply it by 100
= (3/12) * 100
= 25%
