That is false because is percentage is basically x/100, so W:Z is 25/100. Thus, Z:W is 100:25

It would be false for sure because 25% or .25 will be considered with 100 100/.25 and so not forget to put in simplest form so it will be 4 / .1 and that does not equal to 75/25 Hoped that helped !!!!

Question 2(Multiple Choice Worth 5 points) (04.01)The Boardman family walked two over five of a mile in two over seven of an hou
Zolol [24]

Answer:

The unit rate in miles per hour = <em>1.4 miles/hr</em>

Step-by-step explanation:

Given that:

Distance walked by Boardman family = Two over five of a mile = \frac{2}{5}\ miles

Time taken by Boardman family = Two over seven of an hour = \frac{2}{7}\ hour

To find:

The unit rate in the miles per hour = ?

Solution:

Formula for the rate or the speed can be given as:

Speed = \dfrac{Distance}{Time}

Putting the values:

\Rightarrow \dfrac{\frac{2}5}{\frac{2}7}\\\Rightarrow \dfrac{7}{5}\\\Rightarrow \bold{1.4\ miles/hr}

So, the unit rate in miles per hour = <em>1.4 miles/hr</em>

Find the slope of the line. <br> A: -2/3<br> B: 2/3 <br> C: 3:2<br> D: -3/2
tia_tia [17]

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (look at the picture) (0, 1) and (-2, -2). Substitute:

m=\dfrac{-2-1}{-2-0}=\dfrac{-3}{-2}=\boxed{\dfrac{3}{2}}\to\boxed{D}

Which graph represents the function f (x) = StartFraction 4 Over x EndFraction?
beks73 [17]

Answer:

2nd graph (image)

Step-by-step explanation:

The function to graph is:

f(x)=\frac{4}{x}

It follows the general pattern of the function:  f(x)=\frac{1}{x}, which is general shape and in 1st and 3rd quadrants. So, we can eliminate 3rd and 4th choices (because of quadrants).

The answer is either 1st, or 2nd graph.

Now, we simply can check a point in both.

lets take x = 4, so the function would be:

f(4) = 4/4 = 1

Hence, point is:

(4,1)

The first graph doesn't go through this point. The second graph does.

hence, we can successfully choose the 2nd graph as our answer.
