Graven spent $55.20 on gasoline to fill her 15 gallon tank at another gas station project spent $72.80 of gasoline to fill her 20 gallon tank. who paid less per gallon of gasoline explain your reasoning
You must find the unit cost in dollars per gallon for each purchase by dividing the cost by the number of gallons.
Graven: $55.20 for 15 gallons
$55.20/(15 gal) = $3.68/gal
Project: $72.80 for 20 gallons
$72.80/(20 gal) = $3.64/gal
Answer: Project paid less per gallon.
what is 58.14 kg into a lb
It is 128.1 pounds.....
Answer:
There is 127.91lbs in that many kilograms.
Step-by-step explanation:
In order to find this, you need to know the unit rate. There is 2.2lbs in every kilogram. Therefore, we can multiply the number of kilograms that we have by 2.2 to get the correct answer.
58.14*2.2 = 127.91
I need some tips and examples for subtracting integers. Appreciated!
one tip:
Example: 4 - (-3)
it instantly becomes positive because the negatives are close to each other as shown.
hope that helps :)
Since an integer is any whole (not fractional) number on the number line, all you have to do is move to the left however many units you're subtracting by from the point given. Say the problem is 3 - 7. This means we start at 3, and move to the left 7 units, which lands us at -4. However, if we had a problem like 12 - (- 2), the two negatives would cancel out, meaning we will move to the right 2 units on the number line, or 12 + 2, which is 14. Some other examples are:
-12 - 4, (you should get -16)
3 - 8, ( you should get -5)
16 - (- 3), ( you should get 19)
I hope these tips helped you out! I know that when I first had to subtract integers, using a number line really helped me out. Eventually, it'll just be a natural thing. :D
Josh plans to make bird houses to sell at a craft fair the sample of wood he uses has an area of 1/5 square foot in weighs 1/2 lb the local hardware store sells the wood only by the square yard there are 9 square feet in 1 square yard
a. how many pounds of the wood are there in 1 square yard?
b. if Josh needs three square yards of the woods in all how many pounds of the wood does he need
Answer: a.) 22.5 lb and b.) 67.5 lb
Step-by-step explanation:
a.Weight of 1/5 square foot sample of wood = 1/2 lb
Multiplying 5 on both sides we get ,
weight of 1 square foot sample of wood=1/2×5=5/2 lb
Now, 1 square yard = 9 square feet
Thus weight of sample of wood in 1 square yard = 9 ×weight of 1 square foot sample of wood=9×5/2=45/2=22.5 lb
b. Weight of three square yards of wood=3 times weight of wood in 1 square yard
=3×22.5=67.5 lb
Each square foot of wood weighs 2.5 lbs, so one square yard (or 9 square feet) weighs 22.5 lbs. Josh would therefore need 67.5 lbs of wood to construct his birdhouses.
Explanation:This question requires a basic understanding of ratio and proportion. The information given is that Josh's sample of wood, which covers an area of 1/5 square foot, weighs 1/2 lb. However, wood is sold by the hardware store in square yards, and we know that 1 square yard equals 9 square feet.
In other words, each single square foot of wood weighs 2.5 lbs (1/2 lb divided by 1/5). So, the weight of 1 square yard of wood (9 square feet), would be 2.5 lbs per square foot times 9, or 22.5 lbs.
If Josh needs three square yards of wood for his birdhouses, he would therefore need 3 times 22.5 lbs, or 67.5 lbs.

Sean mows lawns in the summer. He charges the same fixed amount for each lawn that he mows. As of today , he has earned $36 after mowing 3 lawns. a. Create an input -‐ output table using the headings “Number of lawns mowed” for the input and “Amount of money in dollars” for the output. Fill in the appropriate values for Sean’s current situation. Then fill in several other rows of information that fit the situation. For example, what if Sean has mowed 8 lawns? 12 lawns?
Step-by-step explanation:
Well we won't give you the table, but it's pretty easy. It's a fixed rate so you know he charges the same thing every time. 36 / 3 = 12
So if he mows the lawn and gets paid $12 each time, you can multiply everthing in your x input to get your y output. So for x = 8 your y output would be y = 96 because 12 * 8 = 96

you and your friends are planning on going to the prom to rent a limi will cost you $200 and an additional $25 for refreshments for each passenger you've already confirmed that you and your best friend will be going however your other three friends haven't gotten back to you yet each friend (including yourself) will bring along their prom date so the possible number of guests is 4-10 (in groups of 2) you need to make a quick budget yo split the potential costs so you utilize some of your mathematics know how
1 write a function for the cost where c is the number of passengers
Cost=
2 identify the domain of this function
3 make a table of values for this domain .write the results as orders pairs in the form (x,y)
The cost function for renting a limo for the prom is Cost(c) = 200 + 25c, where c is the number of passengers. The domain is {4, 6, 8, 10}, representing the possible number of passengers (4 to 10). A table of values for this domain shows the total costs at 300, 350, 400, and 450 respectively for groups of 4, 6, 8, and 10 passengers.
To calculate the cost of renting a limo for the prom including the cost of refreshments based on the number of passengers, we can define a function Cost(c) where c represents the number of passengers. The function can be written as:
Cost(c) = 200 + 25c
The domain of this function is the set of all possible numbers of passengers, which ranges from 4 to 10 (counting in groups of two, since each friend brings a date). Therefore, the domain is {4, 6, 8, 10}.
Next, we'll create a table of values with this domain to calculate the costs associated with each potential number of passengers:
(4, 300)
(6, 350)
(8, 400)
(10, 450)
Each ordered pair represents (number of passengers, total cost).

Ming was planning a trip to Western Samoa. Before going, she did some research and learned that the exchange rate is 6 Tala for $2. How many Tala would she get if she exchanged $6?
Can you please write a proportion with the answer?
Answer:
18 Tala.
Step-by-step explanation:
1. You have that Ming learned that the exchange rate is 6 Tala for $2. Therefore, if she exchanged $6, she would get:
[tex]\frac{6}{2}=\frac{x}{6}[/tex]
2. Now, you must solve for [tex]x[/tex], which is sthe amount of Tala:
[tex]x=\frac{(6)(6)}{2}\\x=\frac{36}{2}\\x =18[/tex]
3. Therefore, she would get 18 Tala.
Write an equation of the line passing through point P(−8, 0) that is perpendicular to the line 3x−5y = 6.
3x - 5y = 6
-3x -3x
-5y = -3x + 6
[tex]\frac{-5y}{-5} = \frac{-3x}{-5} + \frac{6}{-5}[/tex]
[tex]y = \frac{3}{5}x - \frac{6}{5}[/tex] ⇒ m = [tex]\frac{3}{5}[/tex]
perpendicular slope (m⊥) = [tex]-\frac{5}{3}[/tex]
Point-Slope equation:
m = [tex]-\frac{5}{3}[/tex] (x₁ , y₁)= (-8, 0)
y - y₁ = m(x - x₁)
y - 0 = [tex]-\frac{5}{3}[/tex](x - (-8))
y = [tex]-\frac{5}{3}[/tex](x + 8)
y = [tex]-\frac{5}{3}x - \frac{40}{3}[/tex]
how to multiply decimals
Multiply normally, ignoring the decimal points.
Then put the decimal point in the answer - it will have as many decimal places as the two original numbers combined.
So, 16.04 (5.25)=84.21
Answer:
Step one- You first get the decimals -example-( 3.2 x 2.4 )
Step two- You then put the biggest decimal at the top and smallest at the bottom -example-( 3.2
x 2.4 )
You can take away the decimal points for now if it helps.
Step three- You multiply the first number, in this case, the first number is 4. Then multiply the 4 by the top numbers ( Only multiply the 4 an the 2 then multiply the 4 and the 3.)
Then you do the same to the 2 at the bottom.
After you finish multiplying that, then you add the numbers leftover.
Finally you count how many numbers are behind the decimal. In this case, there are 2 numbers behind the decimal, so you would put the decimal 2 numbers behind.
You will begin to see how it works.

when a number is divided by -7 and the quotient is increased by 12, the result is 3. What is the number?
The number is 63 which is divided by -7 and the quotient is increased by 12, the result is 3.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division, thus, can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We have been given that when a number is divided by -7 and the quotient is increased by 12 and the result is 3.
Let the number be x;
x ÷ -7
By hit and trial method, if we consider a number which is a multiplier of 7 and 3.
then it would be 63, now apply this number to the given condition.
63÷ -7 = -9
Also, the quotient is increased by 12, the result is 3.
-9 + 12 = 3
Hence, the number is 63.

A truck can be rented from company a for 130 dollars a day plus .30 per mile. Company b charges 60 dollars a day plus .50 per mile to rent the same truck. Find the number of likes in a day at witch the rental costs for both companies are the same
We know that Company B will be less expensive at first, but Company A will become a better option as the miles rack up. Eventually, Company A will be less expensive. There will be a point where the price will be the same for each company.
150 + .20x = Company A
70 + .40x = Company B
If we set these two equations equal to each other, we find out when the price will be the same.
150 + .20x = 70 + .40x
If we solve for x, we find out how many miles must be driven in a day to make the rental cost the same. After that, Company A will be a better deal.
At 350 miles, the rental costs for company A and company B become the same. This result is found by setting the two cost functions equal to each other and solving for the number of miles.
Explanation:To find when the rental costs from both companies are the same, you need to set the expenses equal to each other and solve for miles (m). The cost for company A can be represented as 130 + 0.30m (130 dollars for the daily rental and 0.30 dollars per mile) and the cost for company B is represented as 60 + 0.50m (60 dollars for the daily rental and 0.50 dollars per mile).
Upon setting the costs equal to each other: 130 + 0.30m = 60 + 0.50m, and simplifying, you'll get 0.20m = 70. Therefore, by dividing by 0.20, m = 350.
So, at 350 miles, the rental costs for both companies A and B are the same, with each charging the same amount for the truck rental.

fifteen added to the product of a number and 6 is 9. find the number
Remark
Start with the product
Let the unknown number = x
The unknown number x is multiplied by 6
At this point you get 6x
====================================
Now you add 15
6x + 15 = 9
Solve
6x + 15 = 9 Subtract 15 from both sides.
6x = 9 - 15 Collect the terms on the right.
6x = - 6 Divide by 6
x = - 6/ 6
x = - 1
(x-2) (x+9)= 4x solve and check solution
Answer:
x = -6 and x=3
Step-by-step explanation:
We have been given the equation to solve
[tex](x-2)(x+9)=4x[/tex]
Let us simplify the left hand side of the equation using FOIL (first outer in last).
[tex]x^2+9x-2x-18=4x\\\\x^2+7x-18=4x\\\\x^2+3x-18=0[/tex]
Now, let us find the factors using AC method.
Middle term 3x can be written as 6x - 3x
[tex]x^2+3x-18=0\\\\x^2+6x-3x-18=0\\\\x(x+6)-3(x+6)=0\\\\(x+6)(x-3)=0\\\\x=-6,3[/tex]
Now, let us check the solution by plugging values in the original equation
For x= -6
[tex](-6-2)(-6+9)=4(-6)\\\\(-8)(3)=-24\\\\-24=-24\Rightarrow\text{ True}[/tex]
Thus, x=-6 is a solution.
For x= 3
[tex](3-2)(3+9)=4(3)\\\\(1)(12)=12\\\\12=12\Rightarrow\text{ True}[/tex]
Thus, x=3 is a solution.
Therefore, the solutions are x = -6 and x=3
