Spent 6 hours of eating pizza

Answer:

The answer to your question is: spend 6 hours eating pizza

Step-by-step explanation:

Data

training = 8 h

eating pizza = 3 h

10 more hours training than eating

hours eating pizza = ?

Process

hours eating pizza = p

hours training = p + 10

                                 

                                     \frac{8}{3} = \frac{10 + p}{p} \\

                                                    8p = 3(10 + p)

                                                    8p = 30 + 3p

                                                    8p - 3p = 30

                                                    5p = 30

                                                   p = 30/5

                                                    p = 6 hours

Consider the graph of the line y = x – 4 and the point (−4, 2).
Hitman42 [59]

Answer:

a. The slope  of a line parallel to the given line is 1

b. A point on the line parallel to the given line, passing through (−4, 2), is  (1,7)

c. The slope of the line perpendicular to the given line is -1

d. A point on the line perpendicular to the given line, passing through (−4, 2), is (3,-5)

Step-by-step explanation:

The equation of the line in Slope-intercept form  is:

y=mx+b

Where m is the slope and b is the y-intercept.

a. For the line y = x - 4

You can identify that:

m=1

 By definition, two lines are parallel if they have the same slope. Then, the  slope of a line parallel to the given line is:

m=1

b. The equation of the line in Point-slope form is:

y -y_1 = m(x - x_1)

Where m is the slope and (x_1,y_1)  is a point of the line.

Given the point (-4,2), substitute this point and the slope of the line into the equation:

 y -2 = (x +4)

Give a value to "x", substitute it into this equation and solve for "y":

For x=1 :

y -2 = (1 +4)

y= 5+2

y= 7

Then, you get the point (1,7)

c. The slopes of perpendicular lines are negative reciprocals, then the  slope of a line perpendicular to the given line is:

m=-\frac{1}{1}\\\\m=-1

d. Given the point (-4,2), substitute this point and the slope of the line into the equation:

 y -2 = -1(x +4)

 y -2 = -(x +4)

Give a value to "x", substitute it into this equation and solve for "y":

For x=3 :

y -2 = -(3 +4)

y= -7+2

y= -5

Then, you get the point (3,-5)

You just multiply the x value by 5
-2(5)=-10
-1(5)=-5
0(5)=0
3(5)=15
6(5)=30

A box of 200 rubber bands costs $1.20. what is the unit price of the rubber bands?
WINSTONCH [101]

Answer:

<u><em>0.006 cents</em></u>


Step-by-step explanation:

divide 1.20 with 200

since a unit price is 1 of something

so 1.20 divided by 200 = 0.006 cents.

0.006 is your answer.
