First one :
We divide it into two rectangles (the top one has dimensions 2in*4in)

The area of the top rectangle is 2*4=8 in^2

The second rectangle has dimensions 3*(5-3)=6 in^2
Hence the total area is 8+6=14 square inches

Second one :
We divide it into a rectangle (dimensions 11*17) and a triangle on the top.

The area of the rectangle is 11*17=187 m^2
The rectangle has dimensions 17 (base's length) and 23-11 (height) hence its area is 17*(23-11)/2=102 m^2

Hence the total area is 102+187=289 square meters

For the first shape split the 'L' into two rectangles; one with a length of 5 inches and a height of 3 inches, we'll call is shape J, the other with a height of 4 inches and a length of 2 inches, this one can be called shape K. (I've basically drawn an imaginary line across the middle). It's a lot easier to work out area this way, simple height multiplied by length. J = 5 x 3 = 15 inches. K = 4 x 2 = 8 inches. Add the two together and you get the area of the whole shape: 23 square inches. *It's important to remember units.* I don't know for sure how to do the second shape (sorry) but I was asked to help out with this question, so I did. I suggest you split the shape again, but this time into a triangle and a rectangle which is far easier to calculate and area for.

$2 \frac{1}{2}+(-2\frac{1}{4})$

This is equal to:

$2\frac{1}{2}-2\frac{1}{4}$

When you add a negative number, it turns into subtraction.

First, I would change it to mixed numbers:

$\frac{5}{2}-\frac{9}{4}$

Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:

$\frac{10}{4}-\frac{9}{4}$

Now, you simply subtract:

10-9=1

1/4 is your answer.

I hope this helps :)

To determine whether the inverse of a function is a function you can perform the horizontal line test.

iris [78.8K]

Answer:

$\boxed{\text{TRUE}}$

Step-by-step explanation:

If a horizontal line intersects the graph of a function in all places at exactly one point (the horizontal line test), the inverse of the function is also a function.

For example, the inverse of a hyperbola (like ƒ(x) =1/x) is a function, because every horizontal line intersects with the graph at exactly one point.

However, the inverse of a parabola (like ƒ(x) = x²) is not a function, because a horizontal line intersects with the graph at two points.

Fifty five miles per hour converted to feet per second

stiks02 [169]

$\frac{55miles}{hour}*\frac{hour}{3600 seconds}*\frac{5280feet}{mile}$
$\frac{55}{1}*\frac{1}{3600 seconds}*\frac{5280feet}{1}=80.67ft/sec$

The product of 8/15, 6/5,1/3 is

Debora [2.8K]

Product is the result of multiplying the numbers, so the product of 8/15, 6/5,1/3 means that we have to multiply the three numbers, like this:

$\frac{8}{15} * \frac{6}{5} * \frac{1}{3}$
let's make them into one fraction:

$\frac{8*6*1}{15*5*3}$

We can simplyfy:

 $\frac{8*6}{15*5*3}$


 $\frac{8*2}{15*5}$

and multiply:

 $\frac{16}{75}$

and this is the correct answer!
