The seventh grade class is putting on a variety show to raise money. It cost $700 to rent the banquet hall that they are going t
Doss [256]
They will need to raise at least 67 tickets because if they sold 66 tickets (15x66) they will only get $990, but if they get 67 tickets (15x67) they'll raise $1005.  The easiest way to get the answer fast is to do 1,000 divided by 15 and then see if that number equals 1000, or if you need to add one more ticket to make it at least 1,000.

To rent a uhal truck for the day, it cost 20 dollars per day plus 1 dollar for every mile driven Write an algebraic expression t
valkas [14]

Answer:

The equation is R = 20d + m(1)

Where R is the rental amount in dollars, d is the number of days and m is the number of miles driven

R for 3 days and 1000 miles is $1,060

Step-by-step explanation:

To properly represent the algebraic expression, we need to assign some variables.

Now, let the rental amount be R, the number of miles driven be m and the number of days rented for is d

Thus, we can say that:

R = 20d+ m(1)

Where R is rental amount, m is the number of miles driven and d is the number of days for which the truck was driven.

Now we are asked to calculate rental amount for 3 days and 1000 miles.

R = 20d + m(1)

R = 20(3) + 1000(1)

R = 60 + 1000

R = $1,060

The circular opening of a tunnel has a circumference of 36 meters. What is the diameter of the tunnel?
Elza [17]
C=2(3.14159...)R
You’re given the circumference, so all you need to do is plug that in and simplify.
36=2(3.14159...)R
36=6.28R
36/6.28=R
R is about 5.73
