A truck can be rented from Company A for $140 a day plus $0.30 per mile. Company B charges $80 a day plus $0.40 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
800 miles
Step-by-step explanation:
140 + (0.30 x 800) = 400$, 800 miles
80 + (0.40 x 800) = 400$, 800 miles
(sorry for incorrect answer the first time, mixed up the cost and number of miles)

What is the measure of the angle
Hey! The measure of the angle is 127
The angle is a total of 180 degrees.
We have to find the total of what's in between the two blue lines.
To make it easier, we can take the total of what's not in the blue lines, 53, and subtract it from 180. This gives us 127. So in between both the blue lines, measures 127. Or, you can just count up from 53 to 180 individually.
Use the distributive property to remove the parentheses.

5/3y=-(x-5) the slope intercept
Answer:
y = - [tex]\frac{3}{5}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
[tex]\frac{5}{3}[/tex] y = - (x - 5) ← distribute parenthesis
[tex]\frac{5}{3}[/tex] y = - x + 5 ( multiply through by 3 to clear the fraction )
5y = - 3x + 15 ( divide terms by 5 )
y = - [tex]\frac{3}{5}[/tex] x + 3 ← in slope- intercept form

Agatha drives 73 1/2 miles through two towns in 2 1/3 hours. What is her average speed in miles per hour?
Answer:
31 1/2
Step-by-step explanation:
average speed = distance/time
average speed = (73 1/2 miles)/(2 1/3 hours)
= (147/2 miles)/(7/3 hours)
= 147/2 * 3/7 miles/hour
= 441/14 miles/hour
= 31 1/2 miles/hour
If you take out a loan for $561.60 over eight years at an interest rate of 9.3%, what is the total amount you will have to repay?
The simple interest of a given sum is directly proportional to the rate of interest. The total amount for repayment is $979.43.
What is Simple interest ?The simple interest is a method of calculating the interest over a sum without considering the compounding.
The simple interest over a period of time varies as arithmetic progression.
Given that,
The amount of loan P = $561.60
Time for the interest T = 8 years.
Rate of interest R = 9.3%.
The total amount A can be given by summing the amount of loan to the interest over it as,
A = P + S.I
And the simple interest is given as,
S.I = (P × R × T) / 100
= (561.60 × 9.3 × 8) / 100
= 417.83.
The amount is given as,
A = 561.60 + 417.83
= 979.43.
Hence, the total amount to be repaid is $979.43.

A line passes through (2, −1) with slope 3. What is the equation of the line in point-slope form?
Hint :- The point slope form of the line is [tex] m(x-x_1) = y - y_1[/tex] , where [tex](x_1,x_2)[/tex] is the point and [tex] m [/tex] is the slope of the line .
Solution :- The given point is [tex](2,-1)[/tex] and the slope is 3 . On using the point slope form of the line, we have ;
[tex]\implies m(x-x_1)=y-y_1[/tex]
Substitute ,
[tex]\implies 3(x -2) = y -(-1) [/tex]
Simplify ,
[tex]\implies 3x -6=y+1 [/tex]
Add -1 and -y to the both sides ,

Mr. Chan places $4000 in a bank as a fixed deposit for 2 years. The bank offers an interest compounded yearly. At the end of 2 years, he receives a total of $4243.60. Find the interest rate.
Answer:
Step-by-step explanation:
Mr. Chan originally placed 4,000 in the bank as a fixed deposit for 2 years.
Each years the bank added a certain amount of interest.
At the end of the 2 years he gained 243 dollars and 60 cents just from interest.
How to solve:
Simply take away the 4 in the amount of money
Leaving: $243.60
( 2 years )
Now divide 243.60 by 1/2
which is 121.8
Mr.Chan got 121.8 worth of interest a year
$10.5 a month
$2.3 a week
6 cents a day
All in 2 years.
