3) Find the area of the polygon below. Give your answer as a number with no label. Assume your answer is square meters.

Answers

Answer:

40 m²

Step-by-step explanation:

Multiply side by side(2 m):

2×4=8 8+8=16

Multiply the perimeter:

8×2=16 4×2=8

add everything:

16+16+8=40

Hope this helps!

The total area equal the rectangle- the two squares
Area of rectangle= base *height
8*4=32m^2

Area of square=side x side
2x2=4m^2
Since there are two squares multiply the answer by 2
4x2=8m^2

Total area=32-8
=24m^2

Here is Laila’s graph from the previous screen.

Write your own equation in the form y=mx+b that could represent Laila’s graph.

Answers

Answer:

y=-1/3x+8

Step-by-step explanation:

There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.

The cost of tuition at the college that Lacy wants to attend is $12,500 per year. Lacy’s family will pay 70% of the tuition cost each year. Lacy has two years to save enough money to attend her first year of college. What is the minimum amount that she should save each month in order to have enough money to attend her first year of college?

$156.25

$729.17

$3,750.00

$312.50

Answers

Answer:

$312.50

Step-by-step explanation:

1: 12,500 x .70 = 8,750

2: 12,500 - 8,750 =3,750

3: 3,750 ÷ 12 = 312.5

Bye Bye :)

The minimum amount that she should save each month in order to have enough money is $312.5

What is percentage?

A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.

Given that, The cost of tuition at the college that Lacy wants to attend is $12,500 per year. Lacy’s family will pay 70% of the tuition cost each year. Lacy has two years to save enough money to attend her first year of college.

The amount Lacy have to pay = (70-30)% of 12500 = 30% of 12500

= 125×30 = $3750

Each month = 3750/12 =32.50

Hence, the minimum amount that she should save each month in order to have enough money is $312.5

USE THE SQUARE ROOT PROPERTY!!!!!

the sides of a square are reduced by 2 inches. the new area is 20 square inches. Set up and solve an equation to find the original length of the square

Answers

Answer:

Step-by-step explanation:

x = original length of one side

(x-2)² = 20 inches²

x-2 = ±√20 = ±2√5

x = 2±2√5

2-2√5 is an extraneous solution,

so x = 2±2√5 ≈ 6.47 inches

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

Answers

the y axis is vertical so it is up and down
Since the 6 is positive the figure will move 6 units up

6 units up: because y axis is top to bottom and the number is positive (versus x axis is left to right).
