A homeowner is deciding on the size of tiles to use to fully tile a rectangular
wall in her bathroom that is 80 inches by 40 inches. The tiles are squares and
come in three side lengths: 8 inches, 4 inches, and 2 inches. State if you
agree with each statement about the tiles. Explain your reasoning.
a. Regardless of the size she chooses, she will need the same number of
tiles.2:
n
b. Regardless of the size she chooses, the area of the wall that is being tiled
is the same.The area of the wall must be the same as the area of the tiles irrespective of the
measure of tiles
c. She will need two 2-inch tiles to cover the same area as one 4-inch tile.
d. She will need four 4-inch tiles to cover the same area as one 8-inch tile.
Area of one 8-inches = 4 *area of one 4-inch tiles 64 = 4*16 64 = 64
e. If she chooses the 8-inch tiles, she will need a quarter as many tiles as
2012
she would with 2-inch tiles.

Answers

Answer:

1) 9/20

2) 5/11

Step-by-step explanation:

For the first question: We read the number "0.45" as "45 hundredths," and we write it as the fraction 45/100. Of course, since 45 and 100 share the common factor 5, we can reduce this fraction by dividing the numerator and denominator by 5 to get the reduced form 9/20.

For our second problem, we need to perform a bit of "mathematical surgery" to find the appropriate fraction for x = 0.454545... First, the dots tell us that this fraction is repeating - those 45s will keep going on and on forever. When we multiply x by 100, then, we move the decimal two places to the right, but the repeating part still remains, giving us

[tex]100x=45.454545\dots[/tex]

From here, we can "surgically remove" the repeating bit using our original value of x:

[tex]100x-x=45.454545\dots-0.454545\dots\\99x=45[/tex]

And from here, we just have to divide both sides of the equation by 99 to solve for x:

[tex]99x=45\\x=45/99\\x=5/11[/tex]

The point (2, -7) is reflected across the x-axis.
What are the coordinates of the image of the point?

Answers

Answer: need more information

Step-by-step explanation: ....

The image of the point (2, -7) after reflection across the x-axis is (2, 7).

What is Reflection?

In mathematics, reflection is a transformation that flips a figure over a line or plane. The line or plane is called the axis of reflection, and each point of the figure and its image are equidistant from the axis of reflection.

We have the coordinates as (2, -7).

Now, the rule for reflection across x- axis is

(x, y) -> (x, -y)

When a point is reflected across the x-axis, its y-coordinate is negated.

Therefore, the image of the point (2, -7) after reflection across the x-axis is (2, 7).

Elsa took out a 2-year loan to buy a car at a 6% simple interest rate.

A. If she has to pay a total of $264 in interest, how much principal did she borrow to pay for the car?

B. How much did she end up paying for her car altogether?

Answers

Step-by-step explanation:

P = I / rt is the formula we're going to use.

P is the principle (which is what we're solving for)

I = the interest accrued over the specified amount of time (2 years)

r = the interest rate (6%)

t = the time specified (2 years)

Change the percent to a decimal. Place the decimal two places to the left to make 0.06.

P = 264 / 0.06(2)

P = 264 ÷ 0.12 = 2,200

Principal borrowed would be $2,200
