Answer:
9 quarters, 12 nickels, and 15 dimes.
Step-by-step explanation:
Let's start by naming the number of quarters x.
That means that the number of nickels is x+3.
(There are three fewer quarters than nickels)
The number of dimes would be x+6.
(There are six more dimes than quarters)
We know the total number of coins is 36.
We can set up an equation.
quarters+nickels+dimes=36
x+x+3+x+6=36
Combine like terms.
3x+9=36
Subtract 9 from both sides.
3x=27
Divide both sides by 3.
x=9
There are 9 quarters.
Use given info to find the number of other coins.
9+3=12
There are 12 nickels.
9+6=15
There are 15 dimes.
Answer:

= 22×5×8
=880
Second Cuboid:
(L×B×H)
=12×5×8
=880
Total Volume:
880+880 = <u>1760</u>

Answer:
41
Step-by-step explanation:
Theorem:
The measure of any exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
The angle measuring b + 41 is an exterior angle.
The angles measuring b - 2 and b + 2 are the remote interior angles to the exterior angle.
According to the theorem:
b - 2 + b + 2 = b + 41
2b = b + 41
b = 41
