1.75

because

a - and a - make a +

so it becomes :

0.25+1.50

which makes 1.75

Which choice shows the image of quadrilateral WXYZ after a reflection over the y-axis followed by a translation down 2 units?

max2010maxim [7]

Answer:

Choices are not provided, but you can answer the question as follows: take the coordinates of quadrilateral WXYZ and apply:

W(xW, yW) -> W'(-xW, yW-2)

X(xX, yX) -> X'(-xX, yX-2)

Y(xY, yY) -> Y'(-xY, yY-2)

Z(xZ, yZ) -> Z'(-xZ, yZ-2)

For example, if point W is located at (1, 1), W' would be located at (-1, -1)

Step-by-step explanation:

Reflection over the y-axis transforms point (x, y) into (-x, y)

Translation down 2 units transforms point (x, y) into (x, y-2)

Step-by-step explanation:

8 Batman cards, 12 Superman cards, and 5 captain America =25 cards

P( batman) = 8/25

no replacement since he hands them out

7 Batman cards, 12 Superman cards, and 5 captain America =24 cards

P( batman) = 7/24

P(batman, no replacement, batman) = 8/25 * 7/24 = 7/75

Deb Boon is single, claims 2 allowances and earns $293.23 each week. If each weekly allowance is $63.46, how much is Deb's taxab

grigory [225]

We are asked to solve for the taxable income. Given and solution are shown below:
Allowances = $63.46 * 2 (since he claims two allowances each week)
Salary = $293.23 per week

Total income for 1 week = $ 293.23 + ($63.46 * 2)
Total income for 1 week = $420.15

In 1 year = $420.15 * 4 weeks in a month * 12 months
In 1 year =$ 20, 167.2

Taxable income is $20,167.2

The area of a rectangular wall of a barn is 280280 square feet. its length is 88 feet longer than twice its width. find the leng

k0ka [10]

Hello,

Making an equation would be a good method to solve this problem.

The area of a rectangle is equal to $l * w$ , where l is the length and w is the width of the rectangle.

If the area of the wall is 280280, we know $l * w$ = 280280
We also know that the length is 88 feet longer than twice the width. Twice the width is equal to $2w$ , and the length is 88 feet longer than that, so $l = 2w + 88$ .

So, we have a system of equations:
$l * w = 280280
$
$l = 2w + 88$

Using the first equation, we can find the value of l and we get $l = \frac{280280}{w}$

We then plug in this value of l into the second equation, and we have:
$\frac{280280}{w} = 2w + 88$

Now, we can multiply by w on both sides, and subtract 280280 on both sides, and use the quadratic formula to get w ≈ 353, -397

The width of a wall cannot be negative, so the answer is 353 feet.

To find l, and make sure of our answers, we should check it with the original problem to make sure it checks out.

Doing this, we get:
$353 * l = 280280$
Divide by 353 on both sides to get:
$l = 794$

Now, we should check it with the equation $l = 2w + 88$
794 = 2(353) + 88
794 = 794, checks out.

So, the width of the wall of the barn is 353 feet, and the length of the wall of the barn is 794 feet.

Hope this helps! Feel free to contact me with any questions you may have.
