Answer:

D) scalene

Step-by-step explanation:

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

Answer: 72

Step-by-step explanation:

6 * 2 = 12

12 / 2 = 6

6 * 2 = 12

12 / 2 = 6

6 * 10 = 60

60 / 2 = 30

6 * 10 = 60

60 / 2 = 30

30 + 30 + 6 + 6 = 72

Answer:

40°

Step-by-step explanation:

angle on a straight line = 180°

therefore

140+ m<BAC = 180°

m<BAC = 40°

Answer:

the angle BAC is 40 degrees

Step-by-step explanation:

(10-6)/(0-24)

=4/(-24)

=0.166

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:

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:

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)

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]

Answer:

that is 6/14, which is 3/7 when simplified.

Step-by-step explanation:

Change 2 into a fraction (2/1)

To divide by a fraction, multiply by its reciprocal (6/7x1/2)

That equals 6/14

Simplify to 3/7

Answer :D

[tex]\frac{3}{7}[/tex] (3/7)

Question explanation:

[tex]\frac{6}{7}[/tex]÷ [tex]\frac{2}{1}[/tex]= 6 x 1 = [tex]\frac{6}{14}[/tex] = (simplifying) = [tex]\frac{3}{7}[/tex]
