Answer:

30.8%

Step-by-step explanation:

To figure this out, set up an equation. 7.7/25 = x/100. This is because 7.7 miles out of 100 is equal to some percentage of 100. Then, solve by simplifying both sides and isolating the variable of x.

Let f(x) = - 13x + 12 and g(x)= x² + 2.--Find f(3)/g(3).f(3)/g(3) = (?)(Type an integer or a simplified fraction.)
mel-nik [20]

We have the next two equations:

f(x)=-13x+12

And

g(x)=x^2+2

We need to find f(3)/g(3)

First, let's find f(3):

f(3)\text{ = -13(3)+12 = -27}

Then g(3):

g(3)=(3)^2+2\text{ = 11}

Now, the equation f(3)/g(3) :

\frac{f(3)}{g(3)}=\frac{-27}{11}

-27/11 is the result.

<em>Note: Since you missed to add the image, so after a little research, I was able to find the image related to this question, which hopefully serves the purpose to clear your concept. The image is attached below.</em>

Step-by-step explanation:

<em><u>Part 1) What is the slope for section "d" of Mrs. Washington's commute</u></em>

Calculating the slope for section "d" of Mrs. Washington's commute:

Slope of the section d  =\frac{y_{2} - y_{1}}{x_{2} - x_{1}}

\frac{6 - 0}{32 - 20}=\frac{1}{2}=0.5

<em><u>Part 2) What does it mean that the slope is negative in context of the problem?</u></em>

The slope is being negative as it is moving downward from the left. In negative slop, the value of x increase, while the vale of y decreases. In positive slop, the value of both x and y increases.

<em><u>Part 3) Why are the slopes different over different intervals?</u></em>

Slopes are different at different intervals as the distance covered in time taken for each part of the given journey are different, also the speed is not the same for each interval.

As the speed can be calculated as

Speed\:=\:\frac{distance}{time}\:

Distance = y_{2} -y_{1} = 20 - 15 = 5

Time = x_{2} -x_{1}= 8 - 0 = 8

Speed = \frac{5}{8}=0.625

Therefore, the speed in the part 1 is 0.625 ms^{-1}

<em><u>Part 4) How long does it take Mrs. Washington to get home? How did you know this?</u></em>

It is clear from the graph that does take 32 minutes to her to get home.  

We can observe it from the graph that it represents the total time taken across the entire journey.

A grocery store sells crackers in three box sizes. Which size box is the best buy? 8 oz for $2.00 12 oz for $2.64 16 oz for $3.2
kvv77 [185]
Hello, <span> <span> schrklar </span> a way to do this is divide the oz by the number, $ 2.00 /</span> 8 = 0.25
$ 2.64 / 12 = 0.22 and $ 3.20 / 16 = 0.2. So the correct answer would be, <span>8 oz for $2.00.</span>
