Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need to drive 240 miles?
Answer:
34
Step-by-step explanation:
ok so first you need to divide 144 by 12 = 12
then you need to figure if you split that in half it equals 6.
now we know that for every 12 miles you drive, you need 1 gallon of gas
now you need to divide 240 by 6 = 40
so you will need 40 gallons of gas to drive that far
we are not one yet, then you need to take away 6 from 40 witch comes to 34.
so you will need 34 more gallons of gas

What is the perimeter of triangle ABC?
Answer: 24 units.
Step-by-step explanation: Count out how many units long AB is. AB goes from -3 to 3, for a length of 6 units.
Count out how long AC is. AC goes from 4 to -4, for a length of 8 units.
To find BC, use the Pythgorean theorem (a^2+b^2=c^2). 8^2 is 64, and 6^2 is 36. Add 64 and 36 to get 100. Then find the square root of 100, which is 10.
Add all the lengths. 6+8+10=24.

8 g + 10 = 35 + 3 g
Answer:
g = 5
Step-by-step explanation:
8 g + 10 = 35 + 3 g
in order to get the value of g, firt of all rearrange the expression or in ither words collect the like terms.
8 g + 10 = 35 + 3 g
8g + 10 - 3g = 35
NOTE; when you are moving a number with positive sign across the equal to = sign the positive changes to negative and same thing applies to the negative sign it changes to positive sign.
we have;
8g -3g = 35 - 10
5g = 25
divide both sides by 5
5g/5 = 25/5
g = 5
Mary mixes white paint and blue paint in the ratio 2:3
She makes a total of 20 litres of paint.
How much more blue paint does she need to add to the mixture so that the ratio of white paint to blue paint becomes 1:7?
Given:
Ratio of white and blue paint is 2:3
Total quantity of paint is 20 litres
To find:
Quantity of blue paint to be mixed so that the ratio of white paint to blue paint becomes 1:7
Solution:
The ratio 2:3 totals 20 that is [tex]2x+3x=20\rightarrow5x=20\rightarrow x=4[/tex]
So, the quantity of white paint in the mixture is [tex]2\times4=8[/tex] and the quantity of blue paint in the mixture is [tex]3\times4=12[/tex]
Now, to get the final ratio as 1:7, Mary should have [tex]7\times8=56 \text{ litres }[/tex] of blue paint. So, she need to add [tex]56-12=44 \text{ litres}[/tex].
Therefore, Mary has to add 44 litres of blue paint to the mixture to make the ratio as 1:7.

The 1 copy makes the cost equivalent in two options and the cost of 1 copy is $41.
Step-by-step explanation:
The given information are that,
Elsa could use a printer in which it cost a $38 setup fee and $3 for each copy.
Elsa could go to a supply store in which it cost $36 up-front fee and $5 for each copy.
To find the same amount for certain number of copies in both the cases :
Let us assume that the number of copies be 'x'.
In the first case, the total cost will be = setup fee + cost for x copies.
⇒ Total cost = 38 + 3x
In the second case, the total cost will be = up-front fee + cost for x copies.
⇒ Total cost = 36 + 5x
To find the x value :
Equating the total cost of both the cases, we get
⇒ 38 + 3x = 36 + 5x
⇒ 38-36 = 5x-3x
⇒ 2 = 2x
⇒ x = 1 copy
Therefore, taking 1 copy make the two options equivalent in terms of cost.
The cost of 1 copy = 38+ 3(1) = 41 dollars.
Therefore, it would cost $41 for 1 copy.

The sum of two numbers is 47 and the difference is 19. What are the numbers?
Answer: The two numbers are 33 and 14
Step-by-step explanation: We shall start by first assigning letters to unknown variables. Therefore let the two numbers be called a and b. The first clue in this question states that the sum of both a and b equals 47. That means we can write the expression;
a + b = 47.
The second clue states that their difference equals 19. This also can be expressed as follows;
a - b = 19
Now we have a pair of simultaneous equations which are
a + b = 47 ———(1)
a - b = 19 ———-(2)
We shall use the substitution method. Therefore from equation (1), make a the subject of the equation.
a = 47 - b
Next we substitute for the value of a in equation (2)
a - b = 19
47 - b - b = 19
47 -2b = 19
By collecting like terms we now have 47 - 19 = 2b
28 = 2b
Divide both sides of the equation by 2
14 = b
We can now substitute for the value of b into equation (1)
a + b = 47
a + 14 = 47
Subtract 14 from both sides of the equation
a = 33.
Therefore the two numbers are 33 and 14.
The two numbers with a sum of 47 and a difference of 19 are 33 and 14. We found this by setting up two equations based on the given information and solving for the two variables.
Explanation:The sum of two numbers is 47 and the difference is 19. To find these two numbers, we can set up a system of equations and solve them. Let the numbers be x and y.
x + y = 47 (equation 1)x - y = 19 (equation 2)Adding both equations, we get 2x = 66, hence x = 33.
Substituting x in equation 1, we get 33 + y = 47, hence y = 47 - 33 = 14.
Therefore, the two numbers are 33 and 14.

A rectangular prism has a length of 4 1/2, a width of 4 1/2 and a height of 6. Sally has a storage container for the prism that has A volume of 143 cubic. What is the difference between the volume of the prism and the volume of the storage container
Question:
A rectangular prism has a length of 4 1/2 millimeters, a width of 4 1/2 millimeters, and a height of 6 millimeters.
Sally has a storage container for the prism that has a volume of 143 cubic millimeters.
What is the difference between the volume of the prism and the volume of the storage container?
Answer:
The difference between the volume of the prism and the volume of the storage container is 21.5 cubic millimeter
Solution:
Volume of rectangular prism is given as:
[tex]volume = length \times width \times height[/tex]
From given,
[tex]length = 4\frac{1}{2} = \frac{9}{2}\ mm\\\\width = 4\frac{1}{2} = \frac{9}{2}\ mm\\\\height = 6\ mm[/tex]
Therefore,
[tex]volume = \frac{9}{2} \times \frac{9}{2} \times 6 = 121.5\ mm^3[/tex]
Sally has a storage container for the prism that has a volume of 143 cubic millimeters
What is the difference between the volume of the prism and the volume of the storage container
Difference = 143 - 121.5 = 21.5
Thus difference between the volume of the prism and the volume of the storage container is 21.5 cubic millimeter

solve the equation 4x — 3y = y —12 for x if y is 6. Make sure to first solve the equation for x in terms of y. X= ________
Answer:
x = 3
Step-by-step explanation:
4x - 3y = y - 12
If y = 6
4x - 3 x 6 = 6 - 12
4x -18 = -6
Add 18 to both sides
4x - 18 + 18 = -6 + 18
4x = 12
Divide both sides by 4
x = 12/4
x = 3
what would the slope of y= -2/5x + 4 be and how can it be broken down for me to understand?
Answer:
So, the slope is the number attached to the x.
In this case the slope is -2/5.
Example: y = 5x + 3
In this case, the slope is 5 because it is the number attached to the x.

John is saving $6 a week. He has already saved $28. How many weeks will it take John to reach his goal of $100?
Answer:
12 weeks
Step-by-step explanation:
If John is aiming to save $100, with $6 a week and he has already saved $28. The leftover amount to be saved is $100 - $28 = $72
In one week → $6
2 weeks → $12
3 weeks → $18
and so on..
[tex]\frac{72}{6} = 12[/tex]
John will need 12 more weeks to save a total of $100.

Step-by-step explanation:
We are given the function:
[tex]y = -5\sin(x)[/tex]
We have to find the range of the given function.
Range of function
Range is the collection of all possible values of y for the domain of function.Range of basic sine function is
[tex]-1\leq \sin(x) \leq 1[/tex]
Multiplying the range by -5
[tex]5\geq -5\sin(x) \geq -5[/tex]
Thus, the range of given function is
[tex]-5\leq -5\sin(x) \leq 5[/tex]
[tex]-5\leq y\leq 5[/tex]
Thus, the range of given function is

A cyclist can cover a distance of 18 miles in 45 minute. How many miles the cyclist can cover in 6 hours?
First, lets find how many miles the cyclist can ride per minute (speed = distance/time).
18/45 = 0.4 miles per minutes
Second, lets find how many miles the cyclist can ride per hour.
0.4 * 60 = 24 miles per hour
Third, lets find how many miles teh cyclist can ride in 6 hours.
24 * 6 = 144 miles in 6 hours
