A truck can be rented from Company A for $120 a day plus $0.50 per mile. Company B charges $30 a day plus $0.80 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.
Answers
90 = 0.3x
x = 300
The charges of both companies will be same if truck is driven 300 miles per day.
It is required to find the number of miles in a day.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.
Given:
Let the truck is driven X miles per day
Charges of company A will be = $120 + $0.50x
Charges of company B will be = $30 + $0.80
Let us find out value of X when charges of both companies are same
Now the following equation should be made
$120 + $0.50x = $30 + $0.80
$120 - $30 = $0.80x - $0.50x
$90 = $0.30x
x = 300 miles.
Therefore, the charges of both companies will be same if truck is driven 300 miles per day.

a lawn mower uses a mixture of gas and oil. for each ounce of oil the mixture contains 10 ounces of gasoline. if the tank holds 99 ounces of the mixture , how many ounces each of oil and gasoline are required to fill the tank completely?
Answers
To fill a 99-ounce tank with a 1:10 oil to gasoline ratio, you need 9 ounces of oil and 90 ounces of gasoline.
Explanation:A lawn mower uses a mixture of gas and oil, with a ratio of 10 ounces of gasoline to every 1 ounce of oil. To find out how many ounces of oil and gasoline are required to fill a 99-ounce tank, we set up a proportion.
Let's denote the amount of oil needed as x ounces. Since the ratio is 1:10, then the amount of gasoline needed will be 10x ounces. The sum of oil and gasoline should equal the tank's capacity:
x ounces (oil) + 10x ounces (gasoline) = 99 ounces (total mixture)Combining like terms gives us:
11x = 99Dividing both sides by 11 yields:
x = 9Therefore, there would be 9 ounces of oil and 90 ounces of gasoline (since 10 * 9 = 90) required to fill the 99-ounce tank completely.
Final answer:
A 99-ounce tank requires 9 ounces of oil and 90 ounces of gasoline to be filled completely, keeping the ratio of 1 ounce of oil to 10 ounces of gasoline.
Explanation:
The question is about determining the correct ratio of oil to gasoline needed to fill a lawn mower's tank, which holds a mixture of the two. Specifically, for every ounce of oil, the mixture requires 10 ounces of gasoline. To find out how many ounces of oil and gasoline are needed for a 99-ounce tank, we can set up a simple proportion. Let's denote the amount of oil as 'o' in ounces, and since for each ounce of oil we need 10 ounces of gasoline, we thus need '10o' ounces of gasoline.
The total mixture is given as 99 ounces, which is the sum of oil and gasoline, so we have the equation: o + 10o = 99.Solving for 'o' gives us o = 9. This represents the ounces of oil needed.To find the amount of gasoline, we multiply the amount of oil by 10, giving us 10*9 = 90 ounces of gasoline.Therefore, to fill a 99-ounce tank, we would need 9 ounces of oil and 90 ounces of gasoline.
Eight bricks are laid end to end along the edge of a flower bed. Each brick is 8 1/2 inches long. How long is the row of bricks in feet
Answers
Answer: The length of row of bricks is 68 inches.
Step-by-step explanation:
Since we have given that
Number of bricks = 8
Length of bricks = [tex]8\dfrac{1}{2}=\dfrac{17}{2}[/tex]
So, Length of the row of bricks is given by
Number of bricks × length of brick
[tex]8\times \dfrac{17}{2}\\\\=4\times 17\\\\=68\ inches[/tex]
Hence, the length of row of bricks is 68 inches.

A Ferris wheel can accommodate 54 people in 24 minutes how many people could ride the Ferris wheel in 2 hours
Answers
First, you need to figure out how many times 24 goes into 120 (120 being the number of minutes in a 2 hour period). When you divide 120 by 24, you get 5.
Next, multiply the number of people (54) by the number of minutes (5) to discover that the Ferris wheel can accommodate 270 people in 2 hours.
The number of people ride the Ferris wheel in 2 hours is 270.
What is multiplication?Augmentation is an activity that addresses the fundamental thought of rehashed expansion of a similar number. The numbers that are multiplied are referred to as the factors, and the result that is produced when two or more numbers are multiplied together is referred to as the product of those numbers. Repeated addition of the same number can be made easier by using multiplication.
Given Ferris wheel can accommodate 54 people in 24 minutes
number of people can ride in 1 minute = 54/24
number of minute in 2 hours is 2 x 60 = 120 minutes
no. of people can ride in 2 hours or 120 minutes is
54/24 x 120 = 270
Hence the 270 people could ride the Ferris wheel in 2 hours.

The sum of the measures of two angles is 180°.
One angle measures 3a and the other angle measures 2a - 25 Find a. Then find the measure of each angle.
Answers
180 = 3a + 2a - 25
combine like terms
180 = 5a - 25
add 25 to both sides
205 = 5a
divide both sides by 5
41 = a
now substitute 41 into the two angles
3(41) = 123
2(41) - 25 = 82 - 25 = 57
so one angle is 123 degrees
the other angle is 57 degrees
to check it, just add 123 + 57 = 180
yep! its correct

how much larger is the LCM than the gcf of 18 and 27?
Explain for points
Answers
The least common multiple, or LCM of 18 and 27 would be 54, in which you find by listing the multiples of both numbers to find the multiple that occurs first and matches with both numbers: 18, 36, 54 27, 54
Now, you have to find the GCF, or the greatest common factor, which is the greatest factor of both numbers that you can take out from both numbers without needing to simplify further. This number would be 9. One way to do this would be listing the factors of both numbers.
18: 1 and 18, 2 and 9, 3 and 6
27: 1 and 27, 3 and 9
Now, to answer the question, you find the difference of the LCM and the GCF. This would be 54-9 which is 45.
