Answer=25

explanation

part/whole = %/100 so

10/ whole = 40/100

to get 10 to 40 you multiply by 4 the you have to do the same to the bottom but since we don’t have a whole we have to divide 100 by 4 which = 25. Hope this helps!!!

Dorothy is using fabric to cover a photo album the width of the fabric is 5/8 of a yard the area of the fabric is 5/16 square ya
saul85 [17]

For this case we assume that the photo album is rectangular in shape and therefore the fabric too. By definition, the area of a rectangle is given by:

A = a * b

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

According to the problem data we have to:

b =\frac {5}{8} \yard\\A = \frac {5} {16} \ yards ^ 2

Substituting:

\frac {5} {16} = a * \frac {5} {8}

We clear "a":

a = \frac {\frac {5} {16}} {\frac {5} {8}}\\a = \frac {5 * 8} {16 * 5}\\a = \frac {8} {16}\\a = \frac {1} {2}

Thus, the length of the fabric is \frac {1} {2} yards.

ANswer:

The length of the fabric is\frac {1} {2} yards.

Find f(x) and g(x) so the function can be expressed as y = f(g(x)) y = Seven divided by x squared. + 10
Damm [24]
F(x) = 7/x
g(x)=x²+10

Then f(g(x))= 7/(x²+10)

By the way    g(f(x))=(7/x)² + 10

What is the slope of the line through (–4, 3) and (5, 3)?
miskamm [114]

Finding the slope using two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =3\\y_{1} =3\\x_{2} =5\\x_{1} =-4

^^^Plug these numbers into the formula for slope...

\frac{3-3}{5 - (-4)}

\frac{0}{9}

0

^^^This is your slope

If your slope is zero that means that the graph will be horizontal

Hope this helped!
