Step-by-step explanation:
f[g(X)]
=f(X+5)
=(x+3)+5
=x+8
Ans: fg(x)=x+8
Answer:
The solution is r=40.
Step-by-step explanation:
First, we identify the parts of the division:
"r" is the dividend of the division.
10 is the divisor
4 is the quotient.
To get the value of "r", we have to make a tape diagram where the divisor represents the number of equal-sized parts (boxes) and the quotient represents de quantity inside the boxes.
The tape diagram is made of 10 equal-sized parts of 4.
So the result is 10×4=40. The value of "r" is 40.

Method 1: you can convert it into a mixed number and simplify
Method 2: you can look at the whole number and that's going to be your first number. then you simplify the fraction. you add the whole number back with you simplified fraction. hoped this helped.
Volume of a cylinder is formulated as: π·r²h
Surface area of a cylinder is formulated as: 2π·rh + 2π·r²
So, for a:
Volume = π·5²·12 = π·25·12 = 300π
Surface area = 2π·5·12 + 2π·5² = 120π + 50π = 170π
And it's essentially the same process for the other questions.
