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?

Answers

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.

The line 2y - x + 5 = 0 and the curve (10 – x)^2+ (y – 5)^ 2= 10 intersect at points A and B.
Find the coordinates of A and of B.​

Answers

Answer:

A(9, 2 ), B(13, 4 )

Step-by-step explanation:

Given the 2 equations

2y - x + 5 = 0 → (1)

(10 - x)² + (y - 5)² = 10 → (2)

Rearrange (1) expressing x in terms of y by adding x to both sides

x = 2y + 5 → (3)

Substitute x = 2y + 5 into (2)

(10 - (2y + 5))² + (y - 5)² = 10, that is

(10 - 2y - 5)² + (y - 5)² = 10

(5 - 2y)² + (y - 5)² = 10 ← expand the factors using FOIL

25 - 20y + 4y² + y² - 10y + 25 = 10

5y² - 30y + 50 = 10 ( subtract 10 from both sides )

5y² - 30y + 40 = 0 ( divide through by 5 )

y² - 6y + 8 = 0 ← in standard form

(y - 2)(y - 4) = 0 ← in factored form

Equate each factor to zero and solve for y

y - 2 = 0 ⇒ y = 2

y - 4 = 0 ⇒ y = 4

Substitute these values into (3) for corresponding values of x

y = 2 : x = 2(2) + 5 = 4 + 5 = 9 ⇒ (9, 2 )

y = 4 : x = 2(4) + 5 = 8 + 5 = 13 ⇒ (13, 4 )

Since we are not given the position of A or B in relation to each other then either of the points can represent A or B, that is

A(9, 2), B(13, 4)

OR

A(13, 4), B(9, 2)

Missing fraction
blank + 1/16 = 3/2

Answers

Final answer:

To solve for the missing fraction in the equation blank + 1/16 = 3/2, convert 3/2 to a fraction with a denominator of 16 to give 24/16. Then, subtract 1/16 from 24/16 to get the missing fraction, which is 23/16.

Explanation:

To find the missing fraction in the equation blank + 1/16 = 3/2, we first need to express 3/2 with the same denominator as 1/16 to facilitate addition. The common denominator for 16 and 2 is 16, so we can rewrite 3/2 as 24/16 (since 3 × 8 = 24 and 2 × 8 = 16). Our equation now is blank + 1/16 = 24/16. To solve for the missing fraction (blank), we subtract 1/16 from 24/16, which gives us 23/16.

Example:

Rewrite 3/2 as 24/16

Subtract 1/16 from 24/16 to find the missing number

The missing fraction is 23/16

This method demonstrates how to find a missing fraction by creating a common denominator and then subtracting to isolate the missing number.

The sum of two numbers is 47 and the difference is 19. What are the numbers?

Answers

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.

Final answer:

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 lizard is jumping across the water in search of food. The equation h = -12t2 + 6t
models the lizard's height in feet above the water t seconds after he jumps. How long
after Jumping is he back on the water?

Answers

Final answer:

To find the time when the lizard is back on the water, set the height equation equal to zero and solve for t. The lizard is back on the water 1/2 second after jumping.

Explanation:

To find the time when the lizard is back on the water, we need to set the height, h, equal to zero, and solve for t in the given equation, h = -12t^2 + 6t.

Substitute 0 for h:

0 = -12t^2 + 6t

Now we can solve for t. Rearrange the equation to quadratic form:

12t^2 - 6t = 0

Factor out a common factor of 6t:

6t(2t - 1) = 0

Set each factor equal to zero:

t = 0 or 2t - 1 = 0

If t = 0, it means the lizard is on the water at the time it jumps. Therefore, t = 0 is not the solution we're looking for. If 2t - 1 = 0, solving for t:

2t = 1

t = 1/2

Therefore, the lizard is back on the water 1/2 second after jumping.

Eric needs to order programs for the next school football game. Only 1 out of 2 people will buy a program for the game. If there will be 900 people at the game and programs come in boxes of 50, how many boxes of programs should Eric order?

Answers

Answer:

Eric should order 9 boxes of programs.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Probability of buying a program for the game = 1/2

Number of people at the game = 900

Number of programs per box = 50

2. How many boxes of programs should Eric order?

Let's calculate the answer this way:

Number of programs required for the next football game = Probability of buying a program for the game * Number of people at the game

Replacing with the values given, we have:

Number of programs required for the next football game = 1/2 * 900

Number of programs required for the next football game = 450

Now, we can calculate he number of boxes, this way:

Number of boxes of programs Eric should order = Number of programs required for the next football game /Number of programs per box

Replacing with the values given, we have:

Number of boxes of programs Eric should order = 450/50

Number of boxes of programs Eric should order = 9

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

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]
