Steve Drive 78 miles on 3 gallons of gas find the miles per gas

Answer:

183.27miles

Step-by-step explanation:

Note that we are considering two planes.

Plane 1

Speed = 140 mph

Time = 2.5 hours

Distance = ?

Speed = distance/time

140 mph = distance/2.5hrs

Distance = 140×2.5

= 350miles

Plane 2

Speed = 170 mph

Time = 2.5 hours

Distance = ?

Speed = distance/time

170 mph = distance/2.5hrs

Distance = 170×2.5

= 425miles

The angle between side is 25 degree

From cosine rule

c^2 = a^2 + b^2 − 2abcos(tetha)

Where a = 350

b = 425miles

c^2 = 350^2+425^2-2(350×425)(cos25)

c^2 = 122500+180625-297500(0.906)

c^2 = 303125-269535

c^2 = 33590

C = √33590

C = 183.27miles

The distance they flew apart after 2.5hrs is 183.27miles

Answer:

  B (rate of change), D (y-intercept)

Step-by-step explanation:

a) The rate of change is found by solving for y. It is the x-coefficient:

  4y = -x +12

  y = -1/4x +3 . . . . divide by 4

The rate of change is -1/4.

__

b) The rate of change can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (10 -4)/(2 -(-2)) = 6/4 = 3/2

The rate of change is 3/2.

__

c) The rate of change can be found by counting grid squares. The line goes down 1 square for each square to the right. The rate of change is ...

  m = rise/run = -1/1 = -1

The rate of change is -1.

__

d) The rate of change is 0.5, the amount paid per box.

__

Of the rates -1/4, 3/2, -1, 0.5, the largest rate of change is 3/2 in relationship B.

_____

a) The y-intercept is the constant in the slope-intercept form equation: +3.

__

b) The y-intercept can be found from the point-slope form equation using the slope we found.

  y -4 = 3/2(x +2)

  y = 3/2x +3 +4

  y = 3/2x + 7

The y-intercept is 7.

__

c) The y-intercept is 4, where the line crosses the y-axis.

__

d) The y-intercept of a proportion is 0.

__

Of the y-intercepts 3, 7, 4, 0, the least y-intercept is 0, in relationship D.

y=55

x=70

Step-by-step explanation:

Answer:

Step-by-step explanation:

Remember, the first point in a bracket like this (6, 1) is the x coordinate. Here, 6 is your x coordinate. So, if we actually had the line (which we don't have right now, it would be lined up with the number 6 on the x axis. And the second point, 1 here, is the y coordinate. Which tells you where this point falls on the y axis. it would be lined up with the number 1 on the y axis. First, let's work on the parts where you are listing the points. it seems to give you the x coordinate 2 on the first one. So on the x axis which is the horizontal line that says Number of Books Sold, go to the number 2. Then y upward with your mouse and the first point that appears with the x coordinate of 2 (it's the 2nd point if you start from the bottom of the line and go up) has the y coordinate of 20 because if you use your mouse to go left on the same gray line that point is on, you will hit 20 on the line that says Total Amount Payed (this is your y axis). Now, on the next point it just gives you the y coordinate, 40. Which means that it should be on the grey line that hits the number 40 on the Total Amount Payed line (your y axis). So if you find that point and go down with your mouse on the gray line right under it, you should hit 4. So that point is  (4, 40). 6 is not labeled but it is the gray line after the 5 on the x axis. If you go up 6, you hit the to right corner of the graph and if you trace it to the y-axis, it's not labeled but it should be 60 because if you pay attention, the numbers on the y-axis are going up by 10s. The x coordinate represents The Number of Books Sold because it says that under the x axis. The y coordinate represents the Total Amount Payed (dollars). ordered pairs are like ratios because they are both pairs. Ordered pairs tell you how much to go up, down, forwards, and backwards on a coordinate plane while ratios tell you a proportion. I am including a picture to help you out. I hope this made sense and was helpful!

Answer:

1200

Step-by-step explanation:

60                 x

-              =    -

100               800

There are 2 ways to solve this.

1) 800 x 60= 48,000

Divide by 100= 480

x=480

2)  Multiply 60 by 8.

Now there are another 2 ways to go.

1) 480        x

   -        =   -

  800        2000

2) 60            x

   -          =    -

   100           2000

To get 2000, 100 must be multiplied by 20. So.... multiply 60 by 20 to get a equal ratio.

Your answer is 1200. Meaning 1200 adults cooked dinner more than four nights per week.

I hope this helps you significantly

Answer:

x = 5

Step-by-step explanation:

[tex]\frac{x}{2x - 3} = \frac{10}{14}[/tex] --> Triangle Proportionality Theorem

10(2x - 3) = 14(x) --> Cross Multiplying

20x - 30 = 14x --> Distributing 10 and 14 to the parentheses

20x -30 - 14x + 30 = 14x - 14x + 30 --> Subtracting 14x and adding 30 on both sides

6x = 30 --> Simplifying

6x/6 = 30/6 --> Dividing 6 on both sides

x = 5 --> Simplifying

Hope this helped!

By the way, I'm not so sure you understand the concept of "Triangle Proportionality Theorem" since you asked a similar one before that. So I'll post an image that I found on the internet that explains it. :D

Answer:

L= 11m

W= 7m

Step-by-step explanation:

Step one:

given data

Let the width W= x

Length = (2x-3)

P= 36 m

Required

The perimeter

P= 2L+2W

36= 2(2x-3)+ 2x

36= 4x-6+2x

collect like terms

36+6= 6x

42= 6x

divide both side by 6

x= 7

the width is 7 m

the length = 2x-3= 2*7-3= 14-3= 11 m

Answer:

Still a segment

Step-by-step explanation:

When a segment is dilated by a scale factor of r = 1, then the segment and its image would be the same length. When the points P and Q are on a line containing the center, then the dilated points P' and Q' will also be col linear with the center producing an image of the segment that is a segment.
