vic is driving 450 miles to his grandma's house. if vic can drive 25 miles per gallon of gas,how many gallons if gas will he use round trip
Answers
Next, you divide 900 by 25, because that will leave you with the amount of gas it needs.
So the answer is 36.

Deborah is planting a rectangular garden. The garden is 15.25 feet long and 12.5 feet wide.
The formula for the area of a rectangle is A=bh.
What is the area of the garden?
Enter your answer as a decimal in the box.
Answers
Answer: [tex]190.625\text{ feet}^2[/tex]
Step-by-step explanation:
Given: Deborah is planting a rectangular garden.
The breadth of the garden (b)= 12.5 feet
The length of the garden (h)= 15.25
The formula for the area of a rectangle is given by :-
[tex]A=bh\\\\\Rightarrow\ A=12.5\times15.25\\\\\Rightarrow\ A=190.625\text{ feet}^2[/tex]
Therefore, the area of the garden = [tex]190.625\text{ feet}^2[/tex]
The height of a ball in feet is modeled by
[tex]y = - 16x {}^{2} + 72x[/tex]
where X is the time in seconds after the ball is hit. How long is the ball in the air?
(May I also get steps on how to solve these kind of questions please?)
Answers
The value of time of the ball in the air is,
⇒ 4.5 seconds
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
We have to given that;
The height of a ball in feet is modeled by the equation,
y = - 16x² + 72x
where, x is the time in seconds after the ball is hit.
Hence, For time of the ball in the air, we can plug y = 0 in above equation.
y = - 16x² + 72x
0 = - 16x² + 72x
Solve for x;
- 16x² + 72x = 0
- 4x (4x - 18) = 0
This gives,
4x = 18
x = 18/4
x = 4.5 seconds
Thus, The value of time of the ball in the air is,
⇒ 4.5 seconds

A) She did not divide 18 by 2.
B)She did not add 2 to 18.
C)She did not multiply 18 by 2.
D) She did not multiply 18 two times.

We have been given the steps to solve the equation as

Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have [tex]2x=18[/tex]
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.

Answers
From looking at the A graph, you must plug in the x variable into y = -2x + 4.
y = -2(0) + 4 = 4
y = -2(1) + 4 = 2
y = -2(2) + 4 = 0
Can you help me list the following stocks and bonds in order from highest default risk to lowest default risk?
-A municipal bond in a city with a population of 150,000
-A common stock in a company under federal investigation
-A preferred stock in a 150-year old firm with good business practices
Answers
From highest to lowest default risk, the investments would likely be ranked as follows: common stock in a company under federal investigation, a municipal bond from a relatively small city, and preferred stock in a stable, long-established firm.
Explanation:The default risk of a financial investment is the likelihood that the issuer of the instrument will be unable to meet their obligations, thereby causing a default. From the highest to lowest default risk, the list would likely be:
Common stock in a company currently under federal investigation: This company has the highest default risk because the investigation could lead to penalties, disruptions in its business, or damage to its reputation.A municipal bond from a city with a population of 150,000: Though generally considered safe, these bonds can still go into default. The default risk here is lower than the stock under investigation because municipal bonds are backed by the taxes and revenue of the municipality, making them more stable than corporations which are dependent on their business performance.A preferred stock in a 150-year old firm with good business practices: This has the lowest default risk. Preferred stocks have a lower risk than common stocks because they receive dividends before common stock and have a higher claim on the assets in case of bankruptcy. The age of the firm and its good business practices also suggest stability and reduced risk. Learn more about Default Risk here:https://brainly.com/question/34906573

In order to solve, you can use substitution. This means that you use one equation and solve for one variable, then use that one equation and plug it into the other equation. Here's how we'd do it:
WORK:
x = 12 - y (since x is already solved for, we'll use that to plug into the other given equation.
2(12 - y) + 3y = 29 (using substitution)
24 - 2y + 3y = 29
24 + y = 29
y = 5
Plug the value of y back into the first equation
x = 12 - 5
x = 7
ANSWER:
A - x = 7, y = 5

9r - 5 - (-4 + 9)
In order to find the sum inside the parenthesis we must keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger. This will look like the following:

Now subtract the numbers and add it back into the expression.
9r - 5 - 5
Now we will calculate the difference between -5 - 5 and add it back into the expression.
9r - 10
Since we cannot simplify this any further,, 9r - 10 is going to be the correct answer to your question.

Write an equation in standard form for the line whose slope is undefined and and passes through (-6,4).
Answers
A vertical line has an equation of the form x = k. In this case, since the line passes thru (-6,4), the eq'n of the line is x = -6.
The equation represents a vertical line passing through the point (-6, 4) is x= -6.
When the slope is undefined, it means that the line is vertical.
In this case, the line passes through the point (-6, 4).
A vertical line has the equation of the form x = k, where k is a constant. Since the line passes through (-6, 4), the equation of the line in standard form is:
x = -6

A pencil costs $0.30 and a pen costs $0.50. You buy 10 pencils and the total Is $7.50. How many pens did buy?
Answers
This is because if you buy 10 pencils, it will cost a total of three dollars. 0.30 times 10=3.00. You then subtract this amount by 7.50, getting 4.50. 4.50 is the total amount that was spent on pens, but since you are trying to figure out how many pens were bought, you divide 4.50 by the cost of one pen (0.50).
This gives you 9.
