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?

Answers

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.

Using the image above, what is the measure of side GF?

Answers

GF is 1.7 units.

tan(60) = 3/x

3 / tan(60)

= 1.73


please mark as brainliest :)

The measure of side GF is solved to be

1.73

How to find the measure of side GF

Too side GF we use trigonometry tan, in the formula

tan x = opposite / adjacent

Where x is the given angle and opposite and adjacent are the legs of the right triangle

In this case, opposite = EF = 3, and adjacent = GF, x = 60 degrees

tan 60 = 3 / GF

Isolating GF results to

GF = 3 / tan 60

GF = 1.73205080757

GF = 1.73

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.

Answers

Answer: C) It has one solution

Step-by-Step Proof:

4y + 6 = -2
4y = -2 - 6
4y = -8
y = -8/4
=> y = -2

Therefore, y = -2

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?

Answers

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.

Divide £350 in the ratio 3:11​

Answers

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.

What is the axis of symmetry?

The axis of symmetry of the quadratic equation is [tex]x = \sqrt 6[/tex]

How to express the solution?

One of the root is given as:

[tex]x = -2 - \sqrt 6[/tex]

As a general rule, the solution to a quadratic equation is represented by:

[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]

This means that the actual root of the given root is:

[tex]x = -2 \pm \sqrt 6[/tex]

So, the other root is:

[tex]x = -2 + \sqrt 6[/tex]

Subtract both roots and divide it by 2 to determine the axis of symmetry

[tex]x = \frac{|-2 - \sqrt 6 + 2 - \sqrt 6|}{2}[/tex]

Evaluate

[tex]x = \frac{|-2\sqrt 6|}{2}[/tex]

Remove the absolute sign

[tex]x = \frac{2\sqrt 6}{2}[/tex]

Divide

The standard form of the equation of a circle of radius r, with (assuming centre h, k) is given as:

(X-h)^2 + (y-k)^2 = r^2

As we are required to write an equation in standard form for the circle with radius 9 centred at the origin.
Centre(h,k)=(0,0), r=9

Substituting these values into the standard form of the equation of a circle given above:

(X-0)^2 + (y-0)^2 = 9^2
X^2 + y^2 =81

The standard form is x^2 + y^2 =81

Which of these functions has the same graph but shifted to the left?

Answers

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.

Simplified form of a term is the simplest way of expression the term, which is obtained  by applying the required operations of mathematics.

Factorial is the way to write the product of the numbers from its phase value to 1 in decreasing order. Suppose, the number is 3!. Then it can be written as,

Answers

Answer:

104 square inches .............

Express 7 square as the sum of two consecutive positive numbers.

Answers

Answer:

24 and 25

Step-by-step explanation:

From given, we have,

7 square = 49

Let the first positive number be = x

And the second consecutive positive number is = x+1

x + (x + 1) = 49

2x + 1 = 49

2x = 49 - 1

2x = 48

x = 24

the first number x = 24

the second consecutive number x+1  = 24 + 1 = 25

Thus, 7 square = 24 + 25 (the sum of two consecutive positive numbers.)
