The temperature drops from 0 degrees to -24 degrees in 6 hours. Which equation represents the average temperature change per hour?

A. (-24) / (6) = 4 degrees per hour
B. (24) / (-6) = 4 degrees per hour
C. (-24) / (-6) = 4 degrees per hour
D. (-24) / (6) = 4 degrees per hour

Answer:

378

Step-by-step explanation:

The question is asking us to solve and write an equation to find the amount of feet he/she climbs in 30 mins

12[tex]\frac{3}{5}[/tex] feet per min: 5 x 12 + 3 =  [tex]\frac{63}{5}[/tex]

(or 30 x [tex]\frac{63}{5}[/tex] = 378 too, many ways to solve this, possibly.)

simplify - multiply = 6 x 63 = 378

(30 x [tex]\frac{63}{5}[/tex] = 378)

(12[tex]\frac{3}{5}[/tex] x 30 = 378)

simplify - multiply = 6 x 63 = 378

(all ways work)

Bye, have a great day.

Answer:

(X + 1) , (Y - 8)

Step-by-step explanation:

With this type of question, I usually like to follow one point as the others will follow the same rules. The Y coordinates of all of H'I'J'K' have been lowered drastically when compared to the original shape, so one can assume that the Y level is not increasing, especially as C would take half the points right off the grid.

By taking H's original coordinate point (in orange) we can see that it moves one forward in the X direction, or +1. Meanwhile, it moves eight down in the Y direction, or -8. Therefore, (X + 1), (Y - 8)

Answer:

well first you would need to find the lowest common denominator for both of these which would be 15 and then divide the top number by the number it takes the denominator to get to 15 which for 2/3 it would become 10/15 and 2/5 would be 6/15 and since the equation wants how much she got rid of it would be 10/15-6/16 which equals 4/15 as your answer which you might be able to simplify

Answer:

use the formula 22/7 x r^2

r is the radius. the radius is half of the diameter. the diameter is the line that cuts the circle into two parts running through the center

Step-by-step explanation:

3a.

there are 40 students.

each one had to get to school one way or another. so, all of them have to be in the table in one category.

I am just surprised that "car" is not an option there.

anyway, we have

11 + 7 + 9 + 6 = 33

so, there are 40-33 = 7 students left for the train category.

3b.

I cannot draw it for you.

but you need to consider the following table :

all 40 students are the full 360° of the circle.

school-bus are 11 students = 11/40 × 360 = 11×9 = 99°

public bus are 7 students = 7/40 × 360 = 7 × 9 = 63°

walk are 9 students = 9/40 × 360 = 9 × 9 = 81°

bicycle are 6 students = 6/40 × 360 = 6×9 = 54°

train are 7 students = 7/40 × 360 = 7 × 9 = 63°

as you can see, the sum is again 40 students and 360°.

you need to draw these 5 pie slices with these angles.

and in each slice you write the number of students in that category.

together, side by side, all 5 slices will fill the whole circle.

Answer:

  (6x² +20x -5)/(x² +6x +8)

Step-by-step explanation:

You want the sum of (5x)/(x+2) and (x² -5)/(x²+6x+8).

Each term can be expressed with the same denominator. Then the numerators can be added.

  [tex]\dfrac{5x}{x+2}+\dfrac{x^2-5}{x^2+6x+8}=\dfrac{5x(x+4)}{(x+2)(x+4)}+\dfrac{x^2-5}{(x+2)(x+4)}\\\\\\=\dfrac{5x^2+20x+x^2-5}{(x+2)(x+4)}=\boxed{\dfrac{6x^2+20x-5}{x^2+6x+8}}[/tex]

Step-by-step explanation:

The triangle shown is a scalene. All three sides of the triangle are different lengths.

Answer:

$20.60

Step-by-step explanation:

$25.75 x 20% = $5.15

$25.75 - $5.15 = $20.60

Answer:

$23.75

Step-by-step explanation:

The longest path from A to B is 36 cm.

It is given that each rectangle in the diagram measures 3 m by 6 cm.

It is required to find the longest path from A to B.

It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.

The formula for finding the area of a rectangle is given by:

Area of rectangle = length × width

We have a rectangle.

Each rectangle's dimensions are 3  cm by 6 cm means:

The width of each rectangle = 3 cm

The length of each rectangle  = 6 cm

In the figure, if calculate the total length of the left side that is:

= 6+6+6

=18 cm

And topside width:

=3+6+6+3

=18 cm

We can say we a rectangle having dimensions 18 by 18.

If we travel from any path the total length will be covered from A to B:

= 18 + 18

=36 cm

As per the direction, we can calculate different path distances.

Thus, the longest path from A to B is 36 cm.

it's C because |-6 - 5| can be simplified to |6+5| which is |11| therefore, the distance is 11 blocks.

Answer:

Question 1: y = x + 4 if x>5

Question 2: y = x

Question 3: y = -x-4

Question 4: y = 3x-6

Step-by-step explanation:

Ok, I will admit, these questions are a bit confusing, but I will try my best.

Question 1: y = |x-3| + |x+2| - |x-5| if x>5. So, let's plug in a number greater than 5 - 6.  y = |6-3| + |6+2| - |6-5|. Inside the absolute value, every number is positive, which pretty much renders the absolute value symbol useless. So, you can take the equation and change the absolute value lines into parentheses.  y = (x-3) + (x+2) - (x-5). In order to get rid of the parentheses, you have to distribute any subtraction symbols which is in front of x-5. This makes our equation  y = x - 3 + x + 2 -x + 5. Combine like terms to get y = x + 4 if x>5.

Question 2: y = |x-3| + |x+2| - |x-5| if -2<x<3. Let's plug in a number between -2 and 3 so 0. y = |0-3| + |0+2| - |0-5|. x-3 becomes a negative number, x+2 becomes a positive number, and x-5 becomes a negative number. Just like question 1, we can leave the x+2 alone since it's a positive number, but we have to change the x-3 and the x-5. So we'll take the equation and change the absolute value to parentheses, but for the values that are negative, we have to put a negative sign in front of to make it positive. Our equation looks like y = -(x-3) + (x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. We distribute the negative to x-3 to make our equation y = -x+3 + x+2 + x-5. Combine like terms to get y = x

Question 3: y = |x-3| + |x+2| - |x-5| if x<-2. Let's plug in -3 since it's less than -2. y = |-3-3| + |-3+2| - |-3-5|. All three parts of the function are negative numbers, so when we change it to parentheses, all parts will have a negative to distribute. Our equation looks like y = -(x-3) -(x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. We distribute the negative to x-3 and x+2 to make our equation y = -x+3 + -x-2 + x-5. Combine like terms to get y = -x-4.

Question 4: y = |x-3| + |x+2| - |x-5| if 3<x<5. Let's plug in 4 since it's in between 3 and 5. y = |4-3| + |4+2| - |4-5|. Only x-5 is negative so that's the only one we need to put a negative in front of when we change it to parentheses. Our equation looks like y = (x-3) + (x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. Our equation is now y = x-3 + x+2 + x-5. Combine like terms to get y = 3x-6.

Hope this helps! :)

Answer:

C: 825

Step-by-step explanation:

Answer: B. perpendicular lines because they intersect at a right angle, making them perpendicular.

Answer:

None of the above

Step-by-step explanation:

Parallel Lines are not shown in this triangle and it is impossible for a triangle to have parallel lines due to its shape. Perpendicular lines are not shown either. Skew lines are only in 3d models and shapes. This is a 2d shape.
