Ms. G, Mr. Adams, and Ms. Leahman are going for a bike ride together on Saturday. They want to meet each other in the city but they all live in Bedstuy. Ms. G and Ms. Leahman have to bike 4 miles there, Mr. Adams is 5 miles away. They meet each other in the city and bike 2 miles together. Then they all return home the same way. How many miles did they all bike in total on Saturday?

Answer:

13/16 = 0.813

Step-by-step explanation:

note: -2.5 is equivalent to the fraction -5/2

==============================================

Explanation:

For now, let's just think of a single number line. If for example we had the values 3 and 7 on it, then 5 would be the midpoint. We find this by adding 3 and 7 to get 10, then cutting in half to get 5.

The value 5 is two units away from both endpoints 3 and 7.

Now let's move onto the 2D xy grid. We'll use the same idea to get the midpoint. Though we'll work on x and y separately. Note how the x axis is basically a number line, and so is the y axis as well. Together those two number lines help pinpoint an exact location.

----------

The endpoints G(-11,4) and H(-1,-9) have x coordinates of -11 and -1. They add to -11+(-1) = -12. Cut this in half to get -12/2 = -6. This is the x coordinate of the midpoint.

Repeat for the y coordinates. G and H have y coordinates of 4 and -9. They add to 4+(-9) = -5 which cuts in half to get -5/2 = -2.5 which is the y coordinate of the midpoint.

Put together, the midpoint is located at (-6, -2.5)

If the midpoint is labeled M, then segments MG and MH are the same length. The midpoint cuts segment GH in half.

Answer:

490.0...

Step-by-step explanation:

4.9 x 10^2

(squared)

4.9 x 10 x 10

the easiest way to do this is to move the decimal 2 places to the right, as

10 x 10 = 100

4.9 x 100 = 490.0...

Answer:

Look below

Step-by-step explanation:

To figure whether a line is perpendicular or parallel check the slopes

When a line is parallel the slopes are the same

When a line is perpendicular the slopes are negative reciprocals

40. Neither (They aren't the same nor a negative reciprocal)

41. Neither (When you put y on the left it isn't a reciprocal)

42. Parallel (The slopes are both -3/2)

To do 43-44 make sure that the slopes are the same then plug in the points to to find the y-intercept (make sure you solve for b)

43. y = -4x - 1

44. y = 2x + 1

For 45-46 do the same thing, but make sure you change the slope to a negative reciprocal since its perpendicular

45. y = -3/2x-11

46. y = 1/4x+4

Answer: in exact form: 291.5 + 30.25π cm²

              correct to 2 decimal places: 386.53 cm²

Step-by-step explanation:

first you find the area of the rectangle:

= length × width

= 53 × 11

= 583 cm²

Next you find the area of the semicircle:

= π × r² (where r is the radius)

= π × (11/2)²

= 30.25π cm²

Then you find the area of the unshaded triangle:

= half × base length × perpendicular height

= 1/2 × 53 × 11

=291.5 cm²

Finally you subtract the unshaded area (the triangle) from the shaded area (not including the semicircle) then add the semicircle to your result.

= 583 (rectangle) - 291.5 (triangle) + 30.25π (semicircle)

= 291.5 + 30.25π

≈ 386.53 cm² (2 decimal places)

therefore it is 3996

Answer:

34

Step-by-step explanation:

So because you are given that a= 14, You just need to replace a with 14 in the equatio so it becomes:

15 + 5 + 14

15 + 5 = 20

20 + 14 = 34

All you do is replace a with 14 then add 15, 5 and 14 getting 34.

Answer:

b = 9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² + 12² = 15²

b² + 144 = 225 ( subtract 144 from both sides )

b² = 81 ( take the square root of both sides )

b = [tex]\sqrt{81}[/tex] = 9

Answer:

4 people

Step-by-step explanation:

Let's first write an equation.

We want to find the number of tickets t

The total was $49 so our equation will equal $49 and they spent $15 in snacks so on the other side of the eqaution we have to add $15, on the same side as the snacks we need to add in the cost of tickets, which is $8.50 multiplies by t, or the total number of tickets.

$49 = $8.50t + $15

Solve for t, first subtract $15 from both sides.

$49 - $15 = $8.50t

$34 = $8.50t   Divide both sides by $8.50

$34/$8.50 =  $8.50t/$8.50  

$34/$8.50 = t

4 = t

4 tickets meaning 4 people went.
