Answer:
Nolan took 97.75 seconds. you may need to round it to 98.
Step-by-step explanation:
multiply 15% by 85 which equals 12.75 then add to 85
Answer:B
Step-by-step explanation:
The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2
1. All you have to do to find the area of the figure. IS first find the area of the rectangle. This is easy because all you have to do is base times height.
22 x 17 = 374
Now to find the area of the triangle all you have to do is do base times height like a rectangle, but then divide it by 2 afterwords.
19 x 12 = 228 ÷ 2 = 114.
Now add the two area's together:
374 + 114 = 488.
Just do the same with the one below, I've altered the pic a bit to make it easier.
Answer:
I think first add the side 137+ 127 +118=382 / 382cm
Dr /dt = 7
A = pi r^2
dA / dr = 2pir
dA/dt = dA/dr * dr/dt = 2pir * 7 = 14pir
when r = 12 rate of change of the area = 14*pi*12 = 168pi
= 527.79 cm^2 / minute to nearest hundredth
