Answer:
The surface area of the second cylinder is equal to 
Step-by-step explanation:
we know that
If two figures are similar then
the ratio of their surfaces areas is equal to the scale factor squared
Let
z-------> the scale factor
x------> the surface area of the smaller cylinder (second cylinder)
y-------> the surface area of the original cylinder (first cylinder)
so
Step 1
Find the scale factor
Step 2
Find the surface area of the second cylinder
we have
substitute and solve for x
The correct answer would be 125
Answer:
3 raise to -7 ÷3 raise to -10 × 3 raise to -5
3 raise to -7-(-10)×3 raise to -5
3 raise to 3×3 raise to -5
3 raise to 3+-5
3 raise to -2
1/3²
1/9
hope it helps you!
Well you're on the right track.
5/(3+4i)=5(3-4i)/(3+4i)(3-4i)=(15-20i)/(3*3-3*4i+4i*3-4i*4i)=(15-20i)/(9+16)=
(15-20i)/(25)=(3-4i)/5
You need to simplify by dividing:
135:100
(Divide both sides by 5 ,as it’s the HCF(Highest Common Factor) )
27:20 ( Keep as whole numbers)
For every R27 Jerry gets , John gets R20.
