In November 2010 the average cost of 5 gallons of regular unleaded gasoline in the United States was $14.46. What was the average cost for 16 gallons of gasoline?
Answer:
$46.72
Step-by-step explanation:
The first step is to find the price of 1 gallon
5 gallons= 14.46
1 gallon= x
5x= 14.46
x= 14.46/5
1 gallon= $2.92
Therefore the cost of 16 gallons of gasoline can be calculated as follows
1 gallon= 2.92
16= x
x= 2.92 × 16
= $46.72

A gymnast's score for a routine is calculated by finding the sum of a difficulty score and an execution score, minus any penalties. The execution score starts at 10 and is reduced by deductions. The gymnast's score can be represented by: 6.9 + (10 – 1.534) – 0.3. What is the gymnast's score?
Answer:
the gymnast score is 15.066
Step-by-step explanation:
The computation of the gymnast score is shown below:
Given that
6.9 + (10 - 1.534) - 0.3
Here the 10 denotes the execution score
6.9 denotes the difficulty score
0.3 denotes the penalties
Based on the above information, the gymnast score is
= 6.9 + (10 - 1.534) - 0.3
= 6.9 + 8.466 - 0.3
= 15.066
Hence, the gymnast score is 15.066

When will Peter's baseball hit the ground? Use mathematical evidence to explain your answer.
Question:
The height of Peter’s baseball is given by the graph below (See attachment)
When will Peter’s baseball reach the highest height? What is the height? When will Peter’s baseball hit the ground? Use mathematical evidence to explain your answer.
Answer:
Peter's baseball reached the maximum height at 1.5 secondsPeter's baseball hit the ground at 4 secondsStep-by-step explanation:
The (a) & (b) will be answered by making reference to the attachment.
Solving (a): Time to reach maximum height
The height is plotted at the vertical axis while the time taken is at the horizontal axis.
From the attachment; the following details can be observed
The maximum height is at 90ftWhen the maximum height is traced to the horizontal axis, the corresponding time is 1.5sUsing function notations, this can be represented as:
[tex]f(1.5) = 90[/tex]
And the interpretation is that:
Peter's baseball reached the maximum height at 1.5 seconds
Solving (b): Time to hit the ground
The interpretation of this question is to solve for the x intercept of the graph.
From the attachment; the following details can be observed
The ground is at 0 feetThe corresponding time at 0 feet is 4sUsing function notations, this can be represented as:
[tex]f(4) = 0[/tex]
And the interpretation is that:
Peter's baseball hit the ground at 4 seconds

The given equation has no solution.
What is equation?
Equation is a statement that show the equality of two expressions connecting by equal sign. for example, 3x - 5 = 20. In this case, 3x - 5 and 20 both are expressions which are connected by equal sign. The two expressions are written on the left side of equal and right side of equal. There are different types of equations such as linear equation, quadatic equation, etc.
The equation is given in the question is 4(x - 8) + 12 = 2(2x -9).
when we find out the solution,
4(x - 8) + 12 = 2(2x -9)
Multiply x with 4 and 2 according to the equation.
4x - 32 + 12 = 4x - 18
4x - 20 = 4x - 18
now, you can see this equation has no solution as the value of x cannot be determined.

Solve 3x+ k = c for x.
Answer:
x=(c-k)/3
Step-by-step explanation:
First, subtract k from both sides of the equation to get: 3x=c-k
Next, divide both sides by 3 to get x by itself=> 3x/3=c-k/3
The threes on the left side cancel, giving you x=(c-k)/3

If 12 X 15 = 180 then what would 24 X15 equal (without solving it on paper)? Is there an easy way to figure out the answer? If so, explain.
Answer:
360
Step-by-step explanation:
It's a simple concept. All you have to do is double the answer! Here's why:
We already know that 12 x 15 is 180. Now we're trying to figure out 24 x 15. 24 is 12 two times, or 12 doubled. Since 12 is doubled, the answer should also be doubled.
Let's take an easier example: 3 x 2.
The answer is 6. What if you doubled the 3 to get 6 x 2? The answer is 12, which is 6 doubled. By doubling the multiplier or multiplicand of the problem, you are also doubling the answer.
It's not just doubling, either. If 3 x 2 is 6. Then 9 x 2 is 18. You tripled the multiplier which is 3, so the answer is also tripled.
Hope this makes some sense lol

The monthly salry of Mr jha is Rs 165000.he spends his income in every month in the following ways food 20 percent house rent 25 percent fuel 10 percent miscellaneous 15 percent find his monthly expenditure on each item. how much does he save every month
Answer:
Total monthly expenditure = Rs 115,500
Total savings = Rs 49,500
Step-by-step explanation:
Total salary = Rs 165000.
Food = 20%
= 20/100 × Rs 165,000
= 0.2 × 165,000
= Rs 33,000
House rent = 25%
= 25/100 × Rs 165,000
= 0.25 × 165,000
= Rs 41,250
Fuel = 10%
= 10/100 × Rs 165,000
= 0.1 × 165,000
= Rs 16,500
Miscellaneous = 15%
= 15/100 × Rs 165,000
= 0.15 × 165,000
= Rs 24,750
Total monthly expenditure = food + house rent + fuel + miscellaneous
= Rs 33,000 + Rs 41,250 + Rs 16,500 + Rs 24,750
= Rs 115,500
Total monthly expenditure = Rs 115,500
Total savings = Total salary - Total expenditure
= Rs 165,000 - Rs 115,500
= Rs 49,500
Total savings = Rs 49,500

Ricardo has $25 to spend on school supplies. He spends 56% of the money on a backpack and the rest on a large binder. How much money does he spend on the backpack? How much does he spend on the binder
Answer:
Ricardo spends $14 on the backpack and $11 o the binder.
Step-by-step explanation:
First, you have to calculate 56% of the amount Ricardo has to spend on school supplies to find the money he spends on the backpack:
$25*56%=$14
Now, you have to subtract 56% from 100% to find the percentage that he spent on a large binder:
100%-56%=44%
Finally, you have to calculate the 44% of the amount Ricardo has to spend on school supplies to find the money he spends on a large binder:
$25*44%=11
According to this, the answer is that Ricardo spends $14 on the backpack and $11 o the binder.

What is the equation of this parabola?
Answer:
y = - x² + 4
Step-by-step explanation:
The equation of a parabola whose vertex is on the y- axis is
y = ax² + c
where a is a multiplier and c is the y- intercept
• If a > 0 then minimum vertex
• If a < 0 then maximum vertex
Here vertex is a max, thus a = - 1 and c = 4
Then equation of parabola is
y = - x² + 4
