An online clothing company sells custom sweatshirts. The company charges ​$4.99 for shipping plus ​$20 for each sweatshirt. Write a linear function rule that models the total cost y​ (in dollars) for any number of sweatshirts x.

Answers

Answer:

20x+4.99=y

Step-by-step explanation:

Each sweatshirt cost $20, but we don't know how many sweatshirts someone will buy so we use X, representing the amount of sweatshirts. There is a shipping charge of $4.99, so we have to add that to the cost of the sweatshirts. 20x+4.99. Y is the total cost.

Find the area using sine rules.

Answers

Answer:

22.44 mi²

Step-by-step explanation:

Step 1

Find the missing angle:

m∠H = 180° - (47° + 99°) = 34°

Step 2

Find the missing sides by using the law of sines:

sin 34° / 5.9 = sin 47° / HP = sin 99° / HKHP = 5.9 sin 47°/sin 34° = 7.7 miHK = 5.9 sin 99° / sin 34° = 10.4 mi

Step 3

Use Heron's formula for the area:

A = [tex]\sqrt{s(s - a)(s - b)(s - c)}[/tex], where s is semi-perimeter, and a, b, c - sides

Find s:

s = 1/2(5.9 + 7.7 + 10.4) = 12

Find A:

A = [tex]\sqrt{12(12 - 5.9)(12 - 7.7)( 12 - 10.4)}[/tex] = 22.44 mi²

In 1979, the price of electricity was $0.05 per kilowatt-hour. The price of electricity has increased at a rate of approximately 2.05% annually. If t is the number of years after 1979, create the equation that can be used to determine how many years it will take for the price per kilowatt-hour to reach $0.10. Fill in the values of A, b, and c for this situation. Do not include dollar signs in the response.
c=A(b)^x

Answers

The equation that can be used to determine the number of years it would take for the price to be $0.10 is 0.10 = 0.05(1.0205)^t.

What is the equation that models the increase?

The equation that would be used is an exponential equation. An exponential equation is used because the rate of increase is a compound growth.

Exponential equations usually have this form: FV = PV( 1 + r)^t

Where:

FV = future value PV = present value r = rate of growth t = time

0.10 = 0.05(1.0205)^t.

Harpo, Groucho, Chico, Zeppo, Gummo, Karl, and Skid have won three tickets to the opera. They will randomly choose three people from their group to attend the opera. How many outcomes are possible?

Answers

Answer:

35

Step-by-step explanation:

This is a combination problem therefore we need to use the combination formula using factorials, plug in the values for n and r which would be 7 since there are 7 individuals in the group and 3 because we are making outcomes of 3.

C(n,r)=C(7,3)

=7!(3!(7−3)!)

=7!3!×4!

= 35

Finally, we can see that the total number of possible outcomes is 35

Step-by-step explanation:

Let Q have coordinates x and y

Using midpoint formula we find the values of x and y

(- 3 + x)/2 = 5 ⇒ -3 + x = 10 ⇒ x = 10 + 3 ⇒ x = 13(6 + y)/2 = 8 ⇒ 6 + y = 16 ⇒ y = 16 - 6 ⇒ y = 10Q = (13, 10)

Answer number 1 plsssss

Answers

Answer:

At Z-Mart, after the discount it is 7/8 of the original price of 225,

at ABC Sports the final price is 200,

and at Bike World, after the discount it is 3/4 of the original price of 265

so

we multiply 225 by 7/8 to get 196.88,

which is lower than ABC Sports,

and then we multiply 265 by 3/4 to get 198.75, which is higher than Z-Mart

so Z-Mart or A) is correct.
