Answer:
2m/5-1/5
Step-by-step explanation:
2*m-2/5+3/5
2(m-2)/5+3/5
2(m-2)/5+3/5
2m-4/5+3/5
2m/5-1/5
I'm perdy sure it's 64/1 but yk it could be something else XD :D good luck!
It is A because I did 100 times 200 and I got 200,000
Part 1) we have that
volume smaller solid=512 cm³
volume larger solid=2197 cm³
we know that
volume larger solid=[scale factor]³*volume smaller solid
scale factor=∛[volume larger solid/volume smaller solid]
scale factor=∛[2197/512]-----> scale factor=1.625
Part 2)
the ratio of the surface areas is equal to [scale factor]²
1.625²-------> 2.64
Part 3)
surface area smaller solid=960 cm²
then
surface area larger solid=scale factor²*surface area smaller solid
surface area larger solid=[1.625]²*960-----> 2535 cm²
surface area larger solid is 2535 cm²
Answer:
Step-by-step explanation:
Given
Balloon velocity is 14 ft/s upwards
Distance between balloon and cyclist is 140 ft
Velocity of motor cycle is 88 ft/s
After 10 sec
motorcyclist traveled a distance of 
Distance traveled by balloon in 10 s
net height of balloon from ground =140+140=280 ft[/tex]
at 
distance between cyclist and balloon is 
now suppose at any time t motorcyclist cover a distance of x m and balloon is at a height of h m
thus 
differentiating w.r.t time
