20 pts But help me with this problem.

Answer:

  a) interior angle: 156°

  b) exterior angle: 24°

Step-by-step explanation:

The sum of the exterior angles of a convex polygon is 360°. Then the exterior angle of a regular 15-gon will be ...

  360°/15 = 24°

__

The interior angle of a convex polygon is the supplement of the exterior angle at that vertex. For an exterior angle of 24°, a regular 15-gon will have an interior angle of ...

  180° -24° = 156°

_____

Additional comment

We find it easier to work this problem by finding the exterior angle first. Note that the results only apply to a 15-gon in which all interior angles are congruent.

14°is the correct answer.

2x-y=4 ..........(1)

x+y=5 ...........(2)

Add equation 1 and 2:

We get:

3x=9

x=9/3

x=3

Substitute value of x in (2):

x+y=5

3+y=5

y=5-3

y=2

Answer:

56

Step-by-step explanation:

We can mark the blue cars as x, so now, we have 9:7, and 72:x, we can use cross multiplication to get the value of x, 72*7 = 9x, which we can simplify into 504 = 9x, and can divide both sides by 9 to get 56 = x.

Hope it helped!

Answer:

y= -2x+8

Step-by-step explanation:

the common required form is: y=s*x+i, where s - slope, i - interception.

According to the form and the condition y=-2x+8.

Answer:

3.5 days

Step-by-step explanation:

If it takes 7 pupils 5 days, then it would take 1 pupil 7 times as long, or 35 days.

1 pupil alone cleans the auditorium is 35 days.

10 pupils work 10 times faster than 1 pupil, so 10 pupils take 3.5 days.

Answer:

X = 73, Y = 138

Step-by-step explanation:

There are 600 boys and 800 girls.

We are given the following facts:

We express this as a partitive proportion.

» Solve for x.

Now we to solve for the number of boys and the number of girls.

» Number of boys:

» Number of girls:

Thus, there are 600 boys and 800 girls. The sum of these is the total number of students in Shiloh Middle School.

Answer:

2 minutes

Step-by-step explanation:

700/10 = 70

1 minute = 70 times

140/70 = 2 minutes

Answer:

2 minutes

Step-by-step explanation:

The heart beats 70 times per minute so 70+70=140.

Step-by-step explanation:

Formulas and Formats we'll be using:

Slope Formula: [tex]m=\frac{y2}{x2} -\frac{y1}{x1}[/tex]

Slope-Intercept form: [tex]y=mx+b[/tex]

m = slope

b = y-intercept

Substitute (-6, 10) and (-3, -2) into the slope formula:

[tex]m=\frac{-2}{-3} -\frac{10}{-6}[/tex]

Simplify:

[tex]m=\frac{-12 \div 3}{3 \div 3}=\frac{-4}{1}[/tex]

[tex]m=-4[/tex]

*Per every -4 y, x increases by 1.

Points Included:

(-6, 10)

(-5, 6)

(-4, 2)

(-3, -2)

(-2, -6)

(-1, -10)

(0, -14)

Y-intercept:

Y-intercept represents x when it's equal to 0.

Using our points, we can determine that the y-intercept is at the point:

(0, -14)

-14 is the y-intercept.

Create a Slope-intercept form equation:

Formula: [tex]y = mx + b[/tex]

Substitute the slope, and y-intercept into the equation:

[tex]y=-4x-14[/tex]

Your equation is: [tex]y=-4x-14[/tex]

Answer:That is amazing.

Step-by-step explanation:

tha t is just wonderful news, now what was the question?

Using rotation rules, it is found that the resulting vector is:

v = <1, 4>

When a vector in component form <x,y> is rotated by 270 degrees, the rule is:

<x, y> -> <y, -x>

That is, x and y are switched, and the signal of x changes.

In this problem, the vector is v <-4, 1>, hence:

<-4, 1> -> <1, -(-4)> -> <1,4>

Hence, <1,4> is the resulting vector.

Answer:

f ≤ 1

Step-by-step explanation:

1) Subtract 2 from both sides.

1 - 2 ≤ - f

2) Simplify 1 - 2 to - 1.

- 1 ≤ - f

3) Multiply both sides by - 1.

1 ≥ f

4) Switch Sides.

f ≤ 1

[tex]\\ \sf\longmapsto 1\leqslant 2-f[/tex]

[tex]\\ \sf\longmapsto 1-2\leqslant -f[/tex]

[tex]\\ \sf\longmapsto -1\leqslant -f[/tex]

Multiply -1 on both sides

[tex]\\ \sf\longmapsto f\leqslant 1[/tex]

Answer:

The solution set is {4, -1}

Step-by-step explanation:

6x²- 18x -18 = 6

6x²- 18x -18 - 6 = 0

6x²- 18x -24 = 0

6(x² - 3x - 4) = 0

6(x - 4)(x + 1) = 0

6 = 0 not true

x - 4 = 0 ;   x + 1 = 0

x = 4           x = - 1

The solution set is {4, -1}
