A customer buys 5 books at a bookstore for a total cost of $65. If all the books cost the same amount, how much does 1 book cost?

Answer:

[tex]Halfway = 37.5[/tex] --- above the sea level

Step-by-step explanation:

Given

[tex]Top = 127ft[/tex] --- above sea level

[tex]Valley\ Floor = 52ft[/tex] --- below sea level

Required

Determine the elevation at half way

To do this, we simply add the elevations of the top of the hill and the valley floor.

Then calculate the average by dividing the sum by 2

[tex]Total = Top + Valley\ Floor[/tex]

[tex]Total = 127 + (-52)[/tex]

Note that the negative sign represents below sea level

[tex]Total = 127 -52[/tex]

[tex]Total = 75[/tex]

At half way, the elevation is:

[tex]Halfway = \frac{1}{2} * Total[/tex]

[tex]Halfway = \frac{1}{2} * 75[/tex]

[tex]Halfway = 37.5[/tex] --- above the sea level

Answer:

y=1/2x+11

Step-by-step explanation:

use the slope of one half and the point and put them into point slope form.

y-y1 = m(x-x1) or y-16 = 1/2(x-10), distribute 1/2

y-16=1/2x - 5, add 16 to both sides

y = 1/2x + 11

Answer:

A

Step-by-step explanation:

The problem asks for how long it takes for the temperature to reach the record high, so the number of minutes it takes for the temperature to reach its peak is what's important.

Step-by-step explanation:

First he bought 3 tires which total costed 105, then returned 2, so he got $70 back, meaning he had $35. Then he found 2 $20 bills, which raised his total to $75. Then, he bought a phone for $90, so he has -25 dollars left

Answer:

The angle is [tex]\theta =27.84^o[/tex]

Step-by-step explanation:

From the question we are told that

   The height of the tree is  [tex]h = 47 \ ft[/tex]

    The length of the shadow is  [tex]L = 89 \ ft[/tex]

Generally applying SOHCAHTOA , the angle of elevation is evaluated as

     [tex]tan \theta = \frac{h}{L }[/tex]

=>  [tex]tan \theta = \frac{47}{89}[/tex]

=>  [tex]tan \theta = 0.52809[/tex]

=>   [tex]\theta = tan^{-1} [0.52809 ][/tex]

=>   [tex]\theta =27.84^o[/tex]

Answer:

slope = - 5

Step-by-step explanation:

Slope is the rise/run = - 30 / 6 = -5

Using the points (6, 0) and (0, 30) you get the same:

slope = (30 - 0) / (0 - 6) = - 5

Answer:

  see attached

Step-by-step explanation:

You can make the work a little easier by solving the equation for y:

  x + y = 6

  y = 6 - x . . . . . . . subtract 6 from both sides

Now, you can fill in the x-values and find y quickly. For example, ...

  y = 6 -(-2) = 8 . . . for x = -2

  y = 6 - 3 = 3 . . . . for x = 3

These values are shown in the attached table and graph.

Answer:

  about $12

Step-by-step explanation:

For estimating purposes, you often want to round numbers to 1 or 2 significant digits. The price $4.23 can be rounded to $4. Then 3 such items will cost about ...

  3×$4 = $12

You spent about $12.

_____

Additional comments

Along with an estimate, you often want to estimate the error in the estimate. Here, a first approximation of the error is that it is 3 × $0.20 too low. That is, the estimate of spending will be closer if we revise it upward by $0.60 to $12.60.

We know that even that estimate is low by $0.03 on each of the 3 items, so a better approximation of the spending is $12.60 +0.09 = $12.69.

This has accounted for all of the errors, so the actual spending was $12.69.

0.09 x 8 = .72

0.8 x 8 = 64.0

4 x 8 = 32

20 x 8 = 160

Answer:

C

Step-by-step explanation:

It is C because you get the equivalent from the t and that t is the number 1 so 15×1 is 15

The solution is Option D.

The equation is d = ( 1/15 ) t

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed of Kiran be represented as = s

Let the distance traveled by Kiran be = d

Let the time taken by Kiran to travel d distance be = t

Now , the value of d = 1 mile

The time taken by Kiran t = 15 minutes

So , the speed of Kiran s is given by the formula

Speed = Distance / Time

Substituting the values in the equation , we get

s = d/t

s = 1 / 15 miles / minute

So , the speed is 1/15 miles / minute

Now , the equation to represent the distance d Kiran walks in t minutes is given by

Distance d = Speed s x Time t

d = ( 1/15 ) t

Therefore , the value of d = ( 1/15 ) t

Hence , The equation is d = ( 1/15 ) t

Answer:

y=3/-1x+4

Step-by-step explanation:

Okay so first thing you need to know is that if there is an ordered pair (x, y) where x is 0, your y-intercept is your y. For example, your problem has (0, 4) your x is 0 and your y is 4. Therefore your y-intercept is 4 which is the b. To find your mx, or slope, you need to do (y2-y1)/(x2-x1). Your y2 will be your y in your second ordered pair and your y1 will be in your y in the first ordered pair. Same for your x. So, (4-1)/(0-1) which equals 3/-1. 3/-1 is your slope. So, your answer in slop intercept form is: y= 3/-1x+4. You could also try y= -3x+4 if that makes you more comfortable.
