Martha has two jobs. One pays $15 per hour, and she works at that job 10 hours per week. The other job pays $13 per hour, and she works at that job 30 hours per week. How much money does she make per year?

Answers

Answer:

28,080$

Step-by-step explanation:

One year - 52 weeks.

First job - 15$/h - 10h/w => Income = 15$/h * 10h/w * 52w = 7800$

Second job - 13$/h - 30 h/w => Income = 13$/h * 30h/w * 52w = 20 280$

Total income 7800$ + 20,280$ = 28 080$

What is the difference between a linear solid line and a set of unconnected points? I don't understand. (Giving 15 points!)

Answers

Answer:

A connected, solid, graph is called a continuous graph. A disconnected graph, made of separate dots, is called a discrete graph.

Step-by-step explanation:

A discrete graph shows us that there are no data values between the whole numbers on which the points are plotted. This generally means no decimal portions. However, when representing time, we can have a decimal portion of a year; this means the graph would have values between the whole numbers and would be continuous, or solid.

Linear line is constant & the Non - linear ( unconnected dots ) are not constant which means the rate is constantly changing

Calculate the Area of the square

Answers

Answer: 80 cm ^2

Step-by-step explanation:

Largest square = 11 by 11

Smallest square = 8 by 8

Side of triangle =

a^2 + b^2 = c^2

you can only use this formula for right angled triangles. it's called the pythagorean theory

in this case you are looking for a^2

a^2 + 8^2 = 11^2

a^2 + 64 = 144

a^2 = 144 - 64

a^2 = 80

in this case. the number isn't going to be friendly.

a = 8.9443

a is just that one side of that triangle though.

but in the end

Area of medium square = 80

because

8.9443 x 8.9443 = 80

The answer is 80cm^2

Adding to his frustration was the fact that very few official papers had made their way to him at Mount Vernon. Washington was a stickler for orderly files that he could search at a moment's notice. This was the most important way he kept himself informed about the hundreds of things happening in the fledgling nation. Unfortunately, when the government clerks had panicked and dashed from Philadelphia, they had abandoned all papers and records in boarded-up houses. No one knew where these documents were; and no one was willing to risk his or her life wandering, through the infected city in search of them.

What conclusion does the cause-and-reflect relationship in this passage support?

Washington lacked the information he needed to govern effectively.
Washington got information in other ways so he could govern effectively.
Washington was so angry at the clerks that he did not govern effectively.
Washington was too frustrated by his missing papers to govern effectively.

Answers

Answer:

1.) 471.24

2.) 1231.5

3.) 113.1

Step-by-step explanation: A = pi x r^2 + pi x r x ^2

1.) a = 3.14 x (5)^2 + 3.14 x 5 x ^2

a = 3.14 x 25 + 3.14 x 5 x 25

a = 78.54 + 392.70

a ≈ 471.24

2.) A = 3.14 (7)^2 + 3.14 x (7) x ^2

a = 3.14 x 49 + 3.14 x 7 x 49

a = 153.93 + 1077.57

a ≈ 1231.5

3.) a = 3.14 (3)^2 + 3.14 x 3 x ^2

a = 3.14 x 9 + 3.14 x 3 x 9

a = 28.27 + 84.82

a ≈ 113.1

⦁ Let x = 4.7 and solve both inequalities below. Show your work.
A: × + 6.2 ≥10.9 B: x - 6.2 ≤ - 5

⦁ Look at your answers to question #4. Which inequality is true or false given x = 4.7. Explain your answer.

Answers

Answer:

A is true and B is false.

Step-by-step explanation:

x + 6.2 ≥ 10.9

Replace x for 4.7...

4.7 + 6.2 ≥ 10.9

10. ≥ 10.9 ( So this is true!)

x - 6.2 ≤ - 5

Replace x for 4.7...

4.7 - 6.2 ≤ -5

-1.2 is not ≤ -5 (So this is false!)

A is true and B is false !

A farmer's land is separated into sections of size 3 3/4 acres. Suppose there are 2 1/5 such sections. How many acres of land does the farmer own?
Write your answer as a mixed number in simplest form.

Answers

Answer:

This is simple multiplication of fractions, not too bad!

we have 2 7/9 sections of farmland, each 2 1/5 acres large. To find the total acreage, multiply 2 1/5 by 2 7/9. The first step here is to convert to improper fractions.

To convert to improper fractions, multiply the denominator of the mixed number by the "whole number" portion of it. Then, add the numerator of the mixed number. For example, for 2 1/5, I would multiply 5 * 2 to get 10, then add 1 to get 11. Then, I keep the original denominator, so 11/5.

Let's do the same for 2 7/9. 9 * 2 = 18, then add 7 to get 25. The improper fraction is 25/9.

Now, we multiply the two fractions. This is just multiplying both numerators and both denominators, straight across.

(11*25)/(9*5) = 275/45 => 55/9, so that's the total acreage, or in decimal form, about 6.11 acres.

this is a simple equation with fractions !!
