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$

Answer:

$28,080

Angela delivered 17 bags of ice on TuesdayShe delivered h bags of ice on Wednesday. Each bag of had a mass of 4.53 kilograms. The total mass of the bags of ice she delivered on both days was 80.42 kilograms

Answers

If the question is asking how many bags of ice cream she delivered on Wednesday, the answer would be 1. To solve the equation, you would start by calculating how many bags of ice cream she sold on Tuesday. To do this would would multiply how many bags she sold (17) by the weight of each bag (4.53 kilograms) this equation would look like 17 x 4.53 kilo = 77.01 kilo. You would then subtract it from the goal she sold on both days (80.42). This equation would look like 80.42 - 77.01 = 4.53. Meaning she sold 1 bag on Wednesday! I hope this helps!

⦁ 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 !

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

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

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 !!

1. (3x2)(−2x4) = 3(−2)x2∙4 = 6x8
2. 4a2∙3a5= (4 + 3)a2+5 = 7a7
3. x6∙x∙x3= x6+3 = x

How is solving a two-step equation similar to solving a one-step equation?

Answers

Answer:

Because it is the same concept, now u have to do more work.

For example

1+1 would be a one step equation

and

1+1(5) would be a two step equation

it's just a bit more.

Each step in solving an equation is like solving a one-step equation so solving a two-step equation is similar to solving a one-step equation

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation

We have,

Two steps equation.

Example:

2 + 3 - (3 x 4)

Step 1:

2 + 3 - 12

Step 2:

5 - 12

-7

One-step equation.

Example:

2 + 4

Step 1:

2 + 4

We see that,

Solving a two-step equation is similar to solving a one-step equation because, in the two-step equation, each of the two steps is like one step individually.

Thus,

Solving a two-step equation is similar to solving a one-step equation.

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
