The linear equation is defined as the equation, which can be represented in the form of y=mx+b.
The cost of one pizza is $ 8.99.
Given that,
Cost of salad = $ 11.98Let the cost of pizza be x.The three pizzas cost will be 3x. The total cost of the food items = $ 38.95Now, using the linear equation formula:
Total cost = Cost of three pizzas + Cost of Salad
Substituting the values, the equation becomes:
$ 38.95 = 3x + $ 11.98
$ 38.95 - $ 11.98 = 3x
$ 26.97 = 3x
x = [tex]\dfrac{26.97}{3}[/tex]
x = $8.99
Therefore, the value of each pizza is $8.99.

If a stadium has 15,000 seats sold at $10.00, $12.50, and $15.00 equally distributed in three sections, how much can be made if the stadium sells out?
Answer:
$187,500
Step-by-step explanation:
There must be 15,000/3 = 5,000 seats in each section. Then the total revenue can be ...
5000·$10.00 + 5000·12.50 + 5000·15.00 = 5000·($10 + 12.50 +15.00)
= 5000·$37.50 = $187,500
Stadium revenue can be $187,500 if all seats are sold.
The total earnings from selling out the stadium with tickets priced at $10.00, $12.50, and $15.00, equally distributed, would amount to $637,500.
The total earnings from selling out the stadium would be $15 x 15,000 = $225,000 for tickets priced at $10.00.
For tickets priced at $12.50, the earnings would be $12.50 x 15,000 = $187,500.
Lastly, for tickets priced at $15.00, the earnings would be $15 x 15,000 = $225,000.
To find the total earnings, add the earnings from each section: $225,000 + $187,500 + $225,000 = $637,500.
Suppose that g(x) = f(x – 8). Which statement best compares the graph of g(x) with the graph of f(x)?
A. The graph of g(x) is the graph of f(x) shifted 8 units to the left.
B. The graph of g(x) is the graph of f(x) shifted 8 units down.
C. The graph of g(x) is the graph of f(x) shifted 8 units up.
D. The graph of g(x) is the graph of f(x) shifted 8 units to the right.
The graph of g(x) is the graph of f(x) shifted 8 units to the right.
Option D is correct.
What is shifting of a function?A shift is a rigid translation in that it does not change the shape or size of the graph of the function. All that a shift will do is change the location of the graph. A vertical shift adds/subtracts a constant to/from every y-coordinate while leaving the x-coordinate unchanged.
According to the question
g(x) = f(x – 8)
If the function is shifted to the left it is going to plus(+).
If the function is shifted to the right it is going to minus(-).
Hence, The graph of g(x) is the graph of f(x) shifted 8 units to the right.
Option D is correct.

at the local baseball diamond,the distance from home base to second base is 100 feet. Determine the distance from home base to first base.
Answer:
70.7 ft
Step-by-step explanation:
The triangle formed by home plate, first base, and second base is an isosceles right triangle with hypotenuse 100 ft. Then the side length (base-line distance between bases) is (100 ft)/√2 ≈ 70.7 ft.
___
For an isosceles right triangle with side lengths 1, the hypotenuse can be found from the Pythagorean theorem to be ...
hypotenuse = √(side² + side²) = √(1²+1²) = √2
Then the diamond distances satisfy the proportion ...
hypotenuse/side = 100 ft/(base distance) = √2/1
or ...
base distance = (100 ft)/√2 ≈ 70.71068 ft

A protractor is used to measure an angle. Which of the following could be the measure of the angle if we know it is an acute angle?
125°
75°
0°
it can't be determined
Final answer:
To find an acute angle using a protractor, choose the angle less than 90°. The acute angle could be 75°.
Explanation:
To determine an acute angle using a protractor, we look for an angle that is less than 90 degrees, as acute angles are those that measure less than 90 degrees.
75° could be the measure of the angle as it falls within the range of acute angles.
Hence, in this case, the angle that could be the measure of the acute angle is 75°.

Step-by-step explanation:
1) Divide the numerator by the denominator and multiply by 100, then:
[tex]\frac{9}{20}=0.45*100=45\%[/tex]
2) Write 320 has the numerator and 100 has the denominator, then reduce the fraction:
[tex]\frac{320}{100}=\frac{32}{10}=\frac{16}{5}[/tex]
3) As a decimal:
Divide the numerator by the denominator and add it to the integer part:
[tex]2+0.375=2.375[/tex]
As a percent:
Multiply the decimal number obtained above by 100:
[tex]2.375*100=237.5\%[/tex]
4) As a decimal:
Divide it by 100:
[tex]\frac{0.1}{100}=0.0001[/tex]
As a fraction:
As you can see, the decimal point were moved three spaces to the left. Therefore, the integer 1 is divided by 1000. Write 1 as the numerator and 1000 has the denominator:
[tex]\frac{1}{1000}[/tex]
5) As a percent:
Multiply 1.2 by 100, then:
[tex]1.2*100=120\%[/tex]
As a fraction:
To make 1.2 an integer you must multiply by 10, therefore, 12 will be the numerator and 10 the denominator:
[tex]\frac{12}{10}[/tex]
Reduce it:
[tex]\frac{6}{5}[/tex]
6) As a decimal:
Divide the numerator by the denominator and add it to the integer part:

Recently in a large random sample of teens a proportion of 0.76 teens said they send text messages to friends. the margin of error for a 98% confidence interval was 0.030. (a) what is the sample statistic for the proportion of teens who send text messages to friends
The sample statistic for the proportion of teens who send text messages to friends is 0.76 or 76%. This result was obtained with a 98% confidence interval and a margin of error of 0.03.
Explanation:The sample statistic in this scenario is the proportion of teens who said they send text messages to friends. In statistics, a sample proportion (also known as a sample percentage) is a way to express the count of observations in a category as a ratio or a fraction of the total sample size.
In your case, the sample statistic is 0.76, meaning that 76% of the teens in your sample said they send text messages to friends. This result was accompanied by a margin of error of 0.030 for your 98% confidence interval.
A confidence interval gives an estimated range of values which is likely to include an unknown population parameter, the estimated range being calculated from a given set of sample data.
The margin of error represents the range in which we are confident that the true population proportion lies given our sample statistic. With a confidence level of 98%, we are sure that if we repeated our sample many times, 98% of those samples would produce a proportion between 76%- 3% and 76% + 3%.

you lease a car valued at 23,495 for 3 years at $429.95/month with a $500 down payment. If interest is 30% of the payment, how much interest is paid over the 3 years?
Solution:
Present Value of car= $ 23,495
Down Payment = $ 500
Total Amount paid monthly for 3 years that is 36 months, if you pay $ 429.95 per month=$ 15478.20
Total amount paid for the car as an agreement which includes Down payment of $ 500 as well as monthly Payment of $ 429.95 for 36 months= $ 15478.20+$ 500=$ 15978.20
As, given Interest is 30% of the payment.
So, total interest = 30% of $ 15978
[tex]=\frac{30}{100}\times 15978.20[/tex]
= $ 4793.40
But if you will calculate interest on payment of $ 429.95 at the rate of 30%, it gives
[tex]=\frac{30}{100}\times 429.95[/tex]
= $128.985
So, total interest for 3 years= $128.985 ×36=$ 4643.46
Also, if you will calculate interest on payment of ($500+$429.95=$929.95) at the rate of 30%
[tex]=\frac{30}{100}\times 929.95[/tex]
=$278.985
Total interest for 3 years= $278.985 ×36=$10,043.46
In the month of January, a certain restaurant claimed it sold 9,000 burgers and expects sales to grow at a rate of 4.8% per month over the next year. Which formula will determine the number of burgers the restaurant expects to sell this year?
Answer:
[tex]y=9000(1.048)^x[/tex]
Step-by-step explanation:
This will be an exponential growth problem. This is because the amount of burgers is expected to change at the same rate every month.
These equations are of the form
[tex]y=a(1+r)^x[/tex],
where a is the original amount, r is the growth rate and x is the amount of time.
In this problem, the original amount, a, is 9000.
The rate of growth is 4.8%; 4.8% = 4.8/1000 = 0.048
This gives us
[tex]y=9000(1+0.048)^x\\\\y=9000(1.048)^x[/tex]
Answer:
The answer is 9000(1.048)^t {limit from n = 1 to n = 12}.

There are 31 quarter inches in 7 3/4 inches. This is determined by converting the mixed number into an improper fraction and then dividing by ¼, which gives us 31/4 or 31 quarter inches.
Explanation:The question asks how many quarter inches there are in 7 3/4 inches. To find this, we can convert the mixed number into an improper fraction and then divide by the fraction representing a quarter inch (¼ inch).
First, convert 7 ¾ to an improper fraction by multiplying the whole number 7 by the denominator 4 and then adding the numerator 3. This gives us 28 + 3 = 31, so 7 ¾ inches is equivalent to ⅔31/4 or 31 quarter inches. Therefore, 7 3/4 inches is 31 quarter inches long.
