Lucy is painting one wall in her bedroom. The wall measures 13 feet long and 9 feet wide. If one can of paint covers 50 square feet will it be enough?

Answers

The area of the wall is figured by length * width.
Area of wall = 13*9=117 square feet
Since one can covers only 50 square feet you will not have enough with one can. You will need 117/50=2.34 cans. Assuming you can only buy full cans you would need to buy 3 cans.

Step-by-step explanation:

B is not a square, it’s a rectangle. It has a area of 5x6=30 cm^2

To the other person you’re correct it’s 30, but you’re wrong to say it’s not a square because if you see A its just a huge square when looking on the length.

Answer:

G. 60 m²

Step-by-step explanation:

The lawn is in the shape of a trapezium.

The area of a trapezium can be found using the equation  0.5*h*(a+b), where h is the height and a and b are the top and bottom of the shape.

Area = 0.5*h*(a+b)

= 0.5*4*(12+18)

= 60 m²

Answer:

  1) x = 4

  2) ? = 20

  8) x = 5

Step-by-step explanation:

Use the applicable relationships to write an equation involving the unknown. Solve the equation.

__

1) We note that the marked arcs are the same length. In a circle, chords that subtend arcs of the same measure are the same length.

  5x -1 = 4x +3

  x = 4 . . . . . . . . . . add 1-4x to both sides

__

2) A tangent meets a radius at right angles. The given triangle is a right triangle, so the Pythagorean theorem applies.

  12² +16² = x²

  144 +256 = x² = 400

  x = √400 = 20

The missing value is 20.

__

8. Tangents from the same point are the same length.

  4x -8 = 12

  4x = 20 . . . . . add 8

  x = 5 . . . . . . . divide by 4

_____

Additional comment

In problem 2, you note the ratio of side lengths is 12 : 16 = 3 : 4. This should give you a clue that this is a 3-4-5 right triangle. The long (missing) side will be 5, scaled by the scale factor of 4, so will be 4×5 = 20.

how can 20% = 1/5 find 20% of 50


Please help asap

Answers

Step-by-step explanation:

Hi,

Think about it this way.

20%

40%

60%

80%

100%

We had to add 20% 5 times in order to get 100%.

The same goes for the fraction.

1/5

2/5

3/5

4/5

5/5

We had to add 1/5 5 times to get it to 5/5.

So...

20% is the same thing as... 20/100 and simplified, it's the exact same thing as 1/5.

They're basically the same exact thing except they're written in different ways.

I hope this helps, I didn't really understand what you needed exactly, but if you need anything else, feel free to let me know :)

Zoey purchased a new car in 1992 for \$28,000$28,000. The value of the car has been depreciating exponentially at a constant rate. If the value of the car was \$9,600$9,600 in the year 1996, then what would be the predicted value of the car in the year 1998, to the nearest dollar?

Answers

400$
Explanation:
In 1992, the price is 28000$ and 9600$ in 1996 so in 4 years the value the car lost is 18400$
Dividing 18400 by 4 years we get 4600 depreciation value per year.
Between 1996 and 1998 there is 2 years
So in 1998 the value of the car will be:
9600 (value in 1996) - 2x4600 = 400$

The predicted value of the car in the year 1998, will be 400$

What is depreciation?

The decrease in the value of any product over a period of time is called depreciation.

In 1992, the price is 28000$ and 9600$ in 1996 so in 4 years the value the car lost is 18400$

Dividing 18400 by 4 years we get 4600 depreciation value per year.

Between 1996 and 1998 there is 2 years

So in 1998, the value of the car will be:

9600   (value in 1996)  -  2  x   4600 = 400$

Therefore the predicted value of the car in the year 1998, will be 400$
