Answer:
I'm sorry if this is wrong but try 16 it's probably wrong tho sorry
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:
y=2x−3
Step-by-step explanation:
you do the slope intercept equation y=mx+ b and find the slope intercept
Answer: he needs $21.50
Step-by-step explanation:
You have to add 22+50=75 then add 15 more to 75 which equals 90....after that you have to divide 7 in half and get 3.5 so now you have to add 90+3.5 and get 93.5. Now you must subtract 93.5-65 and get 28.5 and lastly you subtract 50-28.5 to find out how much money if let to buy VANS.
Answer:
−8x−x21+20
Step-by-step explanation:
1 Collect like terms.
(x-9x)-\frac{1}{{x}^{2}}+20 (x−9x)−x21+20
2 Simplify.
-8x-\frac{1}{{x}^{2}}+20 −8x−x21+20
Hope this helped!! :))
In the screenshot is ur answer btw! :)
