Divide each pound by the cost and you get $1.59
Volume of cylinder =Π r^2 h
where 'r' refers to radius and 'h' refers to height of the cylinder
volume of cylinder = Π (2)^2 (6)
= Π (4)(6)
=Π (24)
75.36 cm^3 is the volume of the cylinder.
A B and D are all equivalent. A and B are just written differently and D can by simplified by divided the numerator and denominator by 5.
Answer:
3 hours
Step-by-step explanation:
Let's express number of hours required for servicing as: x
The auto repair on First Street charges a flat fee of $15 plus $10 an hour for servicing a car.
This is expressed mathematically as:
$15 + $10 × x
= 15 + 10x
The auto repair shop on Second Avenue charges no flat fee but $15 an hour for servicing a car
This is expressed as:
$15 × x
= 15x
The number of hours Malik's car needs to be serviced in order to be able to pay the same amount of money at both shops is calculated as:
Charges by Auto repair shop on First street = Charges by Auto repair shop on Second Avenue
15 + 10x = 15x
15 = 15x - 10x
15 = 5x
5x = 15
x = 15/5
x = 3 hours
Therefore, the number of hours Malik's car needs to be serviced in order to be able to pay the same amount of money at either auto repair shops is 3 hours
Answer:
x = , 6
Step-by-step explanation:
The values of a variable are not possible when it makes the equation divide by 0. To find these values, we need to set each of the denominators equal to 0:
3x + 5 = 0
3x = -5
x =
x - 6 = 0
x = 6
