CAN SOMEONE HELP ME WITH THIS PROBLEM

Mathematics
1 answer:
mestny [16]3 years ago

Hi, I believe the answer is Donna makes 0.2 revolutions per foot of distance traveled and the slope of the graph is 1/5.

To find the number of revolutions per minute you find a point on the graph where the <em>x</em> line and the <em>y</em> line match up, such as (2, 10) then you divide the amount of revolutions in ten feet by ten to find the amount in just one foot, 0.2.

To find the slope of the graph you pick two points on it such as (2, 10) and (4, 20) and subtract the first y coordinate from the second (4 - 2) and do the same with the x coordinates (20 - 10). Then you divide the difference in the y coordinates by the difference in the x coordinates to get the 2/10, then simplify to get 1/5.

Hope this is helpful and not too drawn out :)

What is the distance between (-2, 6) and (-2, -1)
Sloan [31]

Answer:

7 units

Step-by-step explanation:

(-2,6)=(X1,Y1)

(-2, -1)=(X2,Y2)

now ,

distance=√{(x2-x1)^2+(y2-y1)^2}

=√{(-2+2)^2+(-1-6)^2}

=√49

=7 units

Hannah made a ramp for her grandfather who was in a wheelchair. The ramp was 10 ft long and it was 5 ft away from the porch step
lianna [129]

Given :

Length of ramp( Hypotenuse ), l = 10 ft .

Length of base, b = 5 ft .

To Find :

How high were the porch steps.

Solution :

Let, height is h.

By Pythagoras theorem :

b^2+h^2=l^2\\\\h=\sqrt{l^2-b^2}\\\\h=\sqrt{10^2-5^2}\\\\h = \sqrt{75}\\\\h = 5\sqrt{3}\ ft

Hence, this is the required solution.

Write a number sentence that compares 3/5 and 5/6
zavuch27 [327]
To compare 3/5 and 5/6th we need to convert them to a common denominator so if we multiply their denominators we get 5x6 = 30 but we must multlply the numerator by the same number so 3/5 = 18/30th and 5/6 = 25/30 so we see that 25/30 is greater than 18/30th or then 5/6 is greater than 3/5.

Eight times the reciprocal of a number equals 4 times the reciprocal of 2. find the number
uysha [10]

Answer:

The number is 4

Step-by-step explanation:

Let the number  = 'x'

Reciprocal of 'x' = 1/x

Reciprocal of 2 = 1/2

8 times the reciprocal of 'x' = 8*\frac{1}{x}\\

8*\frac{1}{x}= 4* \frac{1}{2}\\\\8*\frac{1}{x}= 2\\

Now multiply both sides by x

8*\frac{1}{x}*x = 2*x\\\\8 = 2x

Now divide both sides by 2

\frac{8}{2}=\frac{2x}{2}\\\\4 = x

x = 4
