P = 2(l+w)
120 = 2(35+w)
120/2 = 35+w
60 = 35 + w
60 -35 = w
25 = w
so width = 25
answer is b. 25 meters
Answer:
y= -1/2x + 3
Step-by-step explanation:
A line perpendicular will have the reciprocal slope.
First you need to find the slope of the line given.
m= rise/ run
m= -2
Now flip for the reciprocal.
The perpendicular line will have a slope of -1/2
Answer:
0.314 gallon is required to cover a circular region with a radius of 40 feet
Step-by-step explanation:
Given
a gallon of paint will cover about 400 square feet in a single coat
To Find:
Number of gallons required to cover a circular region with a radius of 40 feet = ?
Solution:
Step 1: Finding Area of the circular region
The area of the circular region, A =
where r is the radius
Now substituting r = 40 , we get
A =
Step 2: Finding the number of gallons of paint required
To cover 400 sq feet = 1 gallon
so to cover 1 square feet = gallon
Now to cover 125.6 ft we need
=> 0.314 gallon
Answer:
Step-by-step explanation:
The given function is
f(x) = 4x
As we know
f(x) = y, which implies x=
Therefore,
y = 4x
x =
as x=
So,
replacing y by x in the above expression
So our inverse function is
4n-3=4n-2 subtract 4n from both sides
-3=-2
Since -3!=-2, there is no solution.
So your answer is a.
