Mr. Perez brought his daughter and her friends to
the drive-in movie theater. He purchased all the
tickets and spent $28.75 for snacks at the
concession. If he spent a total of $60.00 between
the 5 tickets and concession, how much did each
ticket cost?
Answer: $6.25
Step-by-step explanation:
First, we will find out how much money was spent on tickets.
$60 - $28.75 = $31.25
Now, we will divide the money spent on tickets by the number of tickets bought. This will give us the answer to your problem.
$31.25 / 5 = $6.25
Each ticket cost $6.25.

Does anybody know this?Find the area of the shaded region if PA=7 inches and PB=4 inches
Hi Student!
The first step that we must take before attempting to solve the problem is to gather important information. Looking at the problem we are given two lengths, PA and PB. These two lengths make up the radius of two different circles which we will need to find the area for both of them. The other important information that we must take in is that we are trying to determine the area of the shaded region.
Now that we have our important information concluded, let's move onto solving the problem. We know that we are trying to determine the area of the shaded region which means that we will need to do some subtraction between the total area of the larger circle and the total area of the smaller circle.
Area of a Circle Formula
[tex]A=\pi*r^2[/tex]Plug in the information
[tex]Shaded\ Region = Larger\ Circle - Smaller\ Circle[/tex][tex]Shaded\ Region = (\pi *PA^2)-(\pi*PB^2)[/tex][tex]Shaded\ Region = (\pi *(7\ in)^2)-(\pi*(4\ in)^2)[/tex]Simplify the exponents
[tex]Shaded\ Region = (\pi *49\ in^2)-(\pi*16\ in^2)[/tex]Subtract
[tex]Shaded\ Region = 49\ in^2*\pi-16\ in^2*\pi[/tex][tex]Shaded\ Region = 33\ in^2*\pi[/tex]Therefore, our final answer would be that the shaded region is 33 inches squared times pi which is best described in Option D. We got this after subtracting the area of the smaller circle from the area of the larger circle which provides us with the area of the shaded region.

Divide £350 in the ratio 3:11
Answer:£75, £275
Step-by-step explanation:
The division of the numbers £350 will be £25 and £275.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Divide £350 in the ratio of 3:11.
Let the division in the form of variables be x and y. Then the equation will be
x + y = 350 ...1
x / y = 3 / 11
x = (3/11)y ...2
Put the equation2 in equation 1, then we have
(3/11)y + y = 350
3y + 11y = 3850
14y = 3850
y = 275
Then the value of x will be
x = (3/11) x 275
x = 25
Then the division of the number £350 will be £25 and £275.

Which of these functions has the same graph but shifted to the left?
Step-by-step explanation:
the second and the 6th options keep the same graph but shift it to the left.
the other options :
the first option changes the graph (the factor -2 stretched and flips the graph).
the third and the 5th options shift the graph up and down. but not to the left.
the 4th option shifts it to the right.
when you add a constant inside the x terms, you shift to the left.
when you subtract a constant inside the x terms, you shift to the right.
e.g. when having f(x+2), then everything, that should happen at x+2 happens already at x. 2 units earlier, and therefore a shift to the left.
in the other direction, f(x-2) makes everything that should have happened at x-2 happen finally at x. so, everything shifts 2 units to the right.

Find an explicit function rule for the following sequence defined over the natural numbers: –7, –1, 9, 23, . . .
A. an=9n²+2
B. an=2n²+9
C. an=9n²-2
D. an=2n²-9
===========================================================
Reason:
Replace n with 1 in choice A to get
[tex]a_n = 9n^2 + 2\\\\a_1 = 9(1)^2 + 2\\\\a_1 = 11\\\\[/tex]
Choice A says the first term is 11, but this contradicts the fact that the first term should be -7 instead. Therefore, we cross choice A off the list.
You should find that choice B is the exact same story, so it must be eliminated as well.
Choice C has n = 1 get us [tex]a_1 = 7[/tex] which is close, but we want the result to be negative 7 instead of positive. Choice C is eliminated as well.
The only thing left is choice D. Sure enough, plugging in n = 1 does lead to the first term of -7. If you tried n = 2, then it would get you -1 as the second term, and so on. This confirms choice D is the correct answer.

The triangle PSQ is an isosceles triangle, and the area of the triangle PSQ is 1360.62 square units
How to determine the area?The given parameters are:
PS = SQ
Perimeter, P = 50
SQ - PQ = 1
The perimeter is calculated using:
PS + SQ + PQ = 50
This gives
2SQ + PQ = 50
Make SQ the subject in SQ - PQ = 1
SQ = 1 + PQ
So, the equation 2SQ + PQ = 50 becomes
2(1 + PQ) + PQ = 50
Expand
2 + 2PQ + PQ = 50
Evaluate like terms
3PQ = 48
Divide by 3
PQ = 16
Substitute PQ = 16 in SQ - PQ = 1
SQ - 16 = 1
So:
SQ = 17
The area is then calculated using:
A = √[P * (P - PS) * (P - SQ) * (P - PQ)]
This gives
A = √[50 * (50 - 17) * (50 - 17) * (50 - 16)]
Evaluate
A = 1360.62
Hence, the area of the triangle PSQ is 1360.62 square units

Here, we know there is one point of intersection at x=0, but the line has a slope of 7, not 0. It is not a tangent to the parabola, so there must bet two points of intersection.
Which statement is true about the solutions for the equation 4y + 6 = −2? (5 points) Hint: If you are solving for ONE variable, how many solutions will you have? a It has infinitely many solutions. b It has two solutions. c It has one solution. d It has no solution.
Answer: C) has one solution
That solution is y = -2
=======================================
Work Shown:
4y + 6 = -2
4y = -2-6
4y = -8
y = -8/4
y = -2
I first subtracted 6 from both sides (step 2), then I divided both sides by 4 (in step 4) to fully isolate y. We get one solution here.
Check:
4y + 6 = -2
4(-2) + 6 = -2
-8+6 = -2
-2 = -2
The solution is confirmed.

Billy’s medical bills have been sent to a collection agency. He’s been stressed out for the past few days because agents have been calling him in the early hours of the morning and warning him they’ll have to report him because he has committed a crime. What do you tell Billy? Do you have any advice on what he can do?
Answer:
First of all, I could inform Billy that collection agencies cannot falsely claim that he had committed a crime or say that he will be arrested if he does not repay the money he owes. Failing to repay a medical bill in a timely manner would not land him in prison.
The law also states that debt collectors are not allowed to harass debtors. They are not permitted to call in the early hours of the morning and call repeatedly. Billy can actually order collectors to stop contacting him.
Next, as his account/medical debt had already been sold to collections, he should contact the collection agency to work out payment arrangements. If he is unable to pay the debt in full, some collection agencies may offer a settlement amount. Once he has paid off the account, the collection agency will notify the credit reporting companies it reports to that the account should be updated to note it has been paid in full. He should check to see how his account is appearing by ordering a copy of his report from each of the three credit reporting agencies.
After all these, Billy should then work on rebuilding his credit score.

Hi~!
Answer:
843
Step-by-step explanation:
We know that 58 is a even number, and so is 48,894. So we can check this by multiplying 843, which is th number I got when I divided it, and multiply that by 58, then we get 48,894.
I hope this helps!~ :)
Answer:
843
Step-by-step explanation:
In long division, first take the first digit of the dividend from the left. Check if this digit is greater than or equal to the divisor, then divide it by the divisor and write the answer on top as the quotient. After, subtract the result from the digit and write the difference below. Bring down the next digit of the dividend (if present). Lastly, repeat the same process.
