1. Judy took $15 with her to spend on popcorn and drinks for herself and her friends at the movie theater. The price for each bag of popcorn was $3. The price of each drink was half the price of a bag of popcorn.
(a) Sketch the graph that represents the situation and label the intercepts. Use one axis to represent the number of bags of popcorn and the other axis to represent the number of drinks
I cant figure it out-

Answers

You know that the popcorn cost $5.00 so the drinks would cost $2.50 each. So when you plot the points you would reach $10.00 for popcorn and have $5.00 for drinks. $15.00 for popcorn and $7.50 for drinks.

Step-by-step explanation:

Judy has $30 to spend.

The price per bag of popcorn is $5.

The price per drink is $2.50.

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $25 monthly fee and charges an additional $0.10 for each minute of calls. The second plan has a $12 monthly fee and charges an additional $0.14 for each minute of calls For how many minutes of calls will the costs of the two plans equal

Answers

Answer:

The amount of minutes of calls in which the costs of the two plans equal is 325.

Step-by-step explanation:

To be able to find the amount of minutes of calls in which the cost of the two plans equal, you have to write an expression in which the price of the first and the second plan are the same an solve for the number of minutes:

25+0.10x=12+0.14x, where x is the number of minutes of calls.

Now, you can solve for x:

25-12=0.14x-0.10x

13=0.04x

x=13/0.04

x=325

According to this, the answer is that the amount of minutes of calls in which the costs of the two plans equal is 325.

Create a 5th degree trinomial that has a constant term of 3.

Answers

Answer:

[tex]4x^5\:+\:9x^2\:+\:3[/tex] is a trinomial having three terms, with degree 5 and the constant term '3'.

Step-by-step explanation:

Considering the trinomial

[tex]4x^5\:+\:9x^2\:+\:3[/tex]

As the polynomial contains 3 terms, so it is a trinomial.

As the highest power of the variable 'x' is 5, so the degree of this polynomial is 5.

Any term with no variable is called a constant term. so, 3 is a term with no variable. Therefore, the constant term is 3.

Therefore, [tex]4x^5\:+\:9x^2\:+\:3[/tex] is a trinomial having three terms, with degree 5 and the constant term '3'.

Answers

Step-by-step explanation:

There are several ways to solve this, but the only one I remember how to do is with the pythagorean theorem. The distance between A and B is the same as a hypotenuse of a triangle with a height the absolute value of y1-y2 and a base of the absolute value of x1-x2.

For example, in the first question, the coordinates are (1,2) and (9,8), so we have a triangle with base 8(9 - 1) and 6(8 - 2). Now we just need to plug that into the pythagorean theorem like so:

[tex] {a}^{2} + {b}^{2} = {c }^{2} [/tex]

or plugging our numbers in,

[tex]8^{2} + {6}^{2} = 100[/tex]

The answer is the radical of the answer, in this case 10.

The you add them which equals 1325

Answer:

A) 1325 lbs. B) 10s+15l

Step-by-step explanation:

One small box: 35 lbs (s)

One large box: 65 lbs (l)

If you want to find the total weight for 10 small boxes and 15 large boxes, set up the equation.

10s+15l. This equation is also the answer to part B.

We already know s and l (the weights of the boxes) so plug the values in.

we get:

350+975.

Now add them to get the total weight.

The total weight is 1325 lbs.

The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6
