Answer:

6.8 km/hr

Step-by-step explanation:

If Sara ran 34 km in 300 minutes, then, in one hour, she would run

=> 34 : 300

=> ? : 60

=> 300 / 5  : 34 / 5

=> 60 : 6.8

So, if she travels 6.8 km in 60 minutes, her speed is 6.8 km/hr

Answer:

C. (31)(-10) = -310

Step-by-step explanation:

A. (-9)(-9) = -81

negative times a negative is a positive  incorrect sign

B. (-12)(4) = 48

negative times a positive is a negative incorrect sign

C. (31)(-10) = -310

positive times a negative is a negative correct sign

D. (26)(3) = -78

positive times a positive is a positive  incorrect sign

Answer:

C. (31)(-10) = -310

Step-by-step explanation:

This equation has the correct sign, because multiplying a positive number and negative number gives you a negative number.

The other answer choices have the wrong signs.

Multiplying 2 negatives together gives a positive, so A is wrong.

Multiplying a negative by a positive gives a negative, so B is wrong as well.

D is wrong because multiplying 2 positive numbers gives a positive number.

So, C is correct.

Answer:

If you want to solve it here is the answer x = 15

Step-by-step explanation:

x/3+10 = 15

x/3+10-10 = 15-10                        (what you do to 1 side you do to the other too)

x/3 = 5

x/3*3 = 5*3

x = 15

Answer:

its 5/3+10=15

Step-by-step explanation:

15/3=5

Answer: 1.) The slope of the longer ramp is 1/12

2.) The longer ramp from the ground to the landing is steeper. 1/12 is steeper than 1/18. A graph of the slope shows this. See attachment.

3.) If you know the run, you can find the rise by multiplying the run by the slope.

4.) The rise from the landing to the door is 1/2 foot or 6 inches.

5.) The total height of the door above the ground is 2 ft or 24 inches.

Step-by-step explanation: Sometimes it helps to draw a sketch of the info given then make notes as you find solutions. (See in attachments)

1.) 1:5/18. Multiply by 2/2. It becomes 3/36. simplify to 1/12

4.) Multiplying 9ft by 1/18

It's the same as dividing 9÷18= 0.5 ft. OR  9 feet is 108 inches. 108÷18 = 6 inches

5.) Given height, ground to landing: 1.5 ft plus calculated  0.5ft = 2 ft.

OR 18 inches + 6 inches = 24 inches

The answers to questions comparing the sections of the Ramp are;

1) Slope = 1/2

2)The first section of the ramp is steeper because it has a greater slope.

3) Multiply the horizontal distance by the slope.

4) Vertical distance from landing to the door = 0.5 ft

5) Total height of the door above the ground = 2 ft

We are given that;

Height of landing above the ground = 1.5 ft

Horizontal distance of first section of ramp to landing = 18 ft

Horizontal distance of second section of ramp from landing to door = 9 ft

Slope of Second section of ramp = 1/18

I have attached an image showing the ramp alongside the given data;

With these given data, let's proceed to answer the question;

From the attached image, we see that for the first section;

vertical height = 9 ft

horizontal distance = 18 ft

Thus, slope = 9/18 = 1/2

The slope for the second section is 1/18 = 0.056

The slope of the first section is greater than that of the second

section and thus we will say the slope of the first section is steeper.

Now, since we know the horizontal distance for this second section as 9 ft and the slope as 1/18, then by proportion, to get the vertical distance (x), we will just multiply the horizontal distance by the slope.

x = 9 × (1/18)

x = 1/2 ft

x = 0.5 ft

Height from the landing to the door = 0.5 ft

Total distance from ground to the door = 1.5 + 0.5 = 2 ft

Answer:

The students score at the end of round one is 2

Step-by-step explanation:

if you start at 0 points

0 - 5 = -5

-5 - 3 = -8

-8 + 17 = 9

9 - 7 = 2

Step-by-step explanation:

y-b=m(x-a)

y--10=1/6(x--6)

y+10=1/6(x+6)

6y+60=1(x+6)

6y+60=1x+6

6y=1x-54

y=1/6x-54/6

y=1/6x-9

The  equation of line is y= 1/6x - 9.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

slope= 1/6

and, passes through (−6,−10)

Now, using slope intercept form

y- a =m (x- b)

y - (-10)= 1/6(x -(-6))

y + 10= 1/6( x + 6)

y + 10 = 1/6x + 1

y= 1/6x - 9

Hence, the equation of line is y= 1/6x - 9.

Yellow = 2/3(Blue)

Step-by-step explanation:

You only really need the first row of the table since it shows the volume of yellow to the volume of blue.

Before we write the equation we have to find the ratio and to do that we divide.

Divide the amount of yellow by the amount of blue:

3.5/ 5.25 = 0.666 = 2/3

now we can write the eqaution:

Yellow = 2/3(Blue)
