Work out the size of an exterior and an interior angle of a regular 16-sided
polygon.
Answer:
exterior angle: 22.5°, interior angle: 157.5°
Step-by-step explanation:
the formula for the measure of each Interior Angle in a regular polygon: [tex]\frac{180(n-2)}{n}[/tex], n = # of sides
=> [tex]\frac{180(16 - 2)}{16}[/tex] = 157.5°
the formula for the measure of each Exterior Angle in a regular polygon: [tex]\frac{360}{n}[/tex]
=> [tex]\frac{360}{16}[/tex] = 22.5°

Alex has six candy bars he wants to cut into fifths. How many 1/5 size pieces will he have
Answer:
30 pieces.
Step-by-step explanation:
According to the word problem, Alex wants to cut all six of his candy bars into fifths.
5/5 = one whole candy bar.
If there will 5 pieces for every candy bar, we can multiply 5 by 6.
5 x 6 = 30.
There will be 30 of the 1/5 size pieces.

find the interior angles of a regular polygon which has 6, 10 and 20 sides
Answer:
(6)=120°
(10)=72°
(20)=36°
Step-by-step explanation:
(n-2)×180°
(6-2)×180°=720°
6÷720°=120°
10÷720°=72°
20÷720°=36°

17) In a triangle ABC, BC=8cm, AC=12cm and angle ABC=120
a) Calculate the length of AB, correct to one decimal place (4marks)
Answer:
17.4cm
Step-by-step explanation
17) In a triangle ABC, BC=8cm, AC=12cm and angle ABC=120
To get the length of AB, we will use the cosine rule
AB² = BC² + AC² - 2(BC)(AC) cos <ABC
AB² = 8² + 12² - 2(8)(12) cos 120
AB² = 64 + 144 - 192cos12
AB² = 208 - (-96)
AB² = 208 +96
AB² = 208 - (-96)
AB² = 304
AB² = 17.4cm
Hence the length of AB is 17.4cm

Answer:
D) (-2, -9)
Step-by-step explanation:
X( -11, 8)
M(-6.5, -0.5)
-11 - (-6.5) = -11 + 6.5 = -4.5
8 - (-0.5) = 8 + 0.5 = 8.5
To get from Midpoint to endpoint:
(x , y) → (x - 4.5, y + 8.5)
Y endpoint:
M(-6.5, -0.5) → (-6.5 + 4.5, -0.5 - 8.5)
Y( -2, -9)
Find the equation of a line that passes through points (9,3) and (-6,5)?
Answer:
Y= X - 31.5
Step-by-step explanation:
find the gradient then the equation
Answer:
y-3 = -2/15 (x-9)
Step-by-step explanation:
First, we should find the gradient, m, which is [tex]\frac{rise (change.in.the.y.value)}{run (change.in.the.x.value)}[/tex]
This is [tex]\frac{3-5}{9-(-6)} =-\frac{2}{15}[/tex]
A linear (straight) line has a general equation y=mx+c
y = [tex]-\frac{2}{15\\}[/tex]x+c
We can rewrite the equation into the general form:
y-y1 = m(x-x1)
where y1 is the value of a y coordinate and x1 is the x value of the coordinate that the y1 value was taken from.
This stems from the idea that 0 = 0.
To make that equation true, we can make both sides equal to 0.
To do that, y - y1 has to be - and x-x1 has to be zero. m can be ignored as anything multiplied by 0 is 0.
Up until here, y1 and x1 are arbitrary constants. They are values that we have to find. However, we don't actually. We have coordinates that the x and y will equal to. (9,3)
Because 9 - 9 = 0 and 3 - 3 = 0, we can state that the value of y1 is 3 and x1 is 9.
Hence, the equation is y-3 = -2/15 (x-9)
You can rearrange the equation to make it into the form y = mx + c, but this is usually not necessary.
I hope this helped.

Which expression is equivalent to 2(3g - 4) - (8g + 3)?
Answer:
Step-by-step explanation:
6g - 8 - 8g - 3
-2g - 11
Answer:
-2g - 11
Step-by-step explanation:
2(3g - 4) - (8g + 3)
Use the distributive property to multiply 2 by 3g - 4.
6g + 2(-4) - (8g + 3)
6g - 8 - (8g + 3)
Find the opposite of 8g + 3.
6g - 8 - 8g - 3
Combine like terms.
-2g - 8 - 3
Subtract 3 from -8 to get -11.
-2g + 11
The expression equivalent to 2(3g - 4) - (8g + 3) is -2g - 11.

What is the best approximation of the length of the radius in a circle with an area of 167 m2?
a. 4.6 meters
b.4.0 meters
c. 2.3 meters
d.5.1 meters
Answer:
r = 7.3 m
Step-by-step explanation:
A = (pi)(radius)^2, so, if A = 167 m^2, r^2 is found as follows:
167 m^2
r^2 = -------------- = 53.158 m^2
3.14
Taking the square root of both sides, we get
r = 7.3 m
This is correct, because A = (pi)(radius)^2 becomes (3.14)(7.3 m)^2 = 167.4 m^2

Answer:
A) They will pay more with the new price plan than the current one.
B) The new price plan is cheaper for 7 games.
Step-by-step explanation:
Current price charges;
$3 to rent shoes
$4 per game
New price plan;
$11 to rent shoes
$2 per game
A) If a customer rents shoes and plays 2 games;
At current price;
Cost = 3 + 4(2) = $11
At new price plan;
Cost = 11 + 2(2) = $15
Thus, they will pay more with the new price plan than the current one.
B) Customer bowls 7 games;
At current price;
Cost = 3 + 4(7) = $31
At new price plan;
Cost = 11 + 2(7) = $25
Thus, the new price plan is cheaper for 7 games.
