b. 80
c. 100
d. 125
e. 250
It is easier to show th anser using fractions.
Do=original diameter
Ao=Original area
Df=Final diameter
Af=Final area
Df=(1+50%)Do=(1+1/2)Do=3/2*Do
Ao=pi/4*(Do)^2
Af=pi/4*(Df)^2=pi/4*(3/2*Do)^2=pi/4*9/...
Comparing the initial and final area:
Af/Ao=(pi/4*9/4*(Do)^2)/(pi/4*(Do)^2)
simplifying
Af/Ao=9/4=225%
Therefore the increment is 9/4-1=5/4=125%
Or equivalently: 225%-100%=125%
Therefore the answer is "D."
Note: there is calculate the increment in the difference not how many times the area changed.
Hope this helps ;)
Answer:
Step-by-step explanation:
To find a quadrant, take the 2 equations and add them together for both x and y. The resulting point's quadrant is the solution.
2x-4=0
add 4 to each side
2x=4
divide by 2
x=2
2-y=0
add 2
y=2
(2,2)
point (2,2) lies in quadrant 1
PLEASE MARK BRAINLIEST
True
False
is -1.
we know that
in the right triangle of the figure
Applying the Pythagorean Theorem
therefore
the answer is the option
C)
The distance between the mountains and her residence is 315 miles.
Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.
Given that Amanda drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 7 hours. when Amanda drove home, there was no traffic and the trip only took 5 hours. if her average rate was 18 miles per hour faster on the trip home.
The distance will be calculated as,
Distance = S x 7
The other distance is,
Distance = 5 ( S + 18 )
7S = 5S + 90
S = 45 miles
Distance = 45 x 7
Distance = 315 miles
