Answer:
∠ BOC = 30°
Step-by-step explanation:
Given ∠ COF = 150°
∠ BOC + ∠ COF = 180° ( BF is a straight angle ) , that is
∠ BOC + 150° = 180° ( subtract 150° from both sides )
∠ BOC = 30°

Nathan has a sculpture in the shape of a pyramid. The height of the sculpture is 3 centimeters less than the side length, x, of its square base.
Nathan uses the formula for the volume of a pyramid to determine the dimensions of the sculpture:
V =äa2h
Here, ais the side length of the pyramid's square base and h is its height.
If 162 cubic centimeters of clay were used to make the sculpture, the equation x3 +
2+
= 0 can be used to find that the

Task #4 Gamers and Game World
Gamers: Two dollars for every game downloaded.
Game World: $15 per month and $0.50 per game downloaded.
a) How much money would it cost if you downloaded 6 games from Gamers? Show your work, using the equation c=2d, where c is the cost and d is the number of downloads.
b) Write an equation for the cost per month at Game World, using c for cost and d for downloads.
c) Which equation is represented in the graph below, Gamers or Game World? Justify your answer using mathematical reasoning.
d) If you plan on downloading 8 games per month, which would be the best plan to buy? Justify your answer using mathematical reasoning.
e) Justin has a membership to Gamers and he says his plan is better than Game World’s. Kenny, who has a membership to Game World, disagrees. Who is correct? Justify your answer using mathematical reasoning.
f) How many games would Justin and Kenny have to download to make the same monthly payment? How do you know?
Answers
Answer:
a)....it would cost 12 dollars
the equation is.... 2x 6(number of downloads)
b) C = 15 + (dx0.5)
c) the graph represents gamers price model
d) gamers would be cheapest
gamers would be 8 x 2 = 16
gameworld would be 15(monthly subs) plus 0.50 x 8 (4 dollars) = 19
e) totally depends upon the number of games downloaded by each person.
for up to 10 games per month Justin is on the best deal
exactly 10 games per month makes both deals equal
over 10 games per month Kenny is on the best deal

In the diagram below, ΔABC ≅ ΔDEF. Therefore, by CPCT, ∠B = ∠E.
What is CPCT?
Corresponding parts of congruent triangles or CPCT is used to denote the relation between the sides and the angles of two congruent triangles.
Since, ΔABC ≅ ΔDEF,
AB = DE
BC = EF
AC = DF
∠A = ∠D
∠B = ∠E
∠C = ∠F

The probability of spinning an odd number, flipping heads and then spinning a 3 is?
Answers
===================================================
Work Shown:
A = probability of landing on an odd number
A = 5/9 because there are 5 odd numbers out of 9 total
B = probability of getting heads
B = 1/2
C = landing on 3 on the spinner
C = 1/9
Multiply the values of A,B,C
A*B*C = (5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162
Note: The fraction 5/162 converts to the approximate decimal 0.03086 which then converts to 3.086%, when rounding to the nearest tenth of a percent we get 3.1%
How do I solve a system of equations algebraically with a substitution method and then write it as a coordinate point?
y = 3x -17 and y = -2x + 8
Answers
It would be:
3x - 17 = -2x + 8
Then solve. First you can add 2x to both sides.
5x - 17 = 8
Add 17 to both sides
5x = 35
Divide both sides by 5.
x = 5
Since we now have x, we can find y by plugging in 5 for x in any of the equations. I will use y = -2x + 8
y = -2(5) + 8
y = -10 + 8
y = -2
We now have both x and y. As a coordinate point, it would be (5, -2).

3= y+7 divided by 3
Y=
Answers
Answer:
y=2
Step-by-step explanation:
3 = (y+7)/3
Multiply each side by 3
3*3 = (y+7)/3 *3
3*3 = y+7
9 = y+7
Subtract 7 from each side
9-7 = y+7-7
2 =y
Answer:
2 = y
Step-by-step explanation:
3 = y + 7 ÷ 3
multiply both side of equation by 3
3 × 3 = y + 7 ÷ 3 / 3
9 = y + 7
subtract 7 from both side
9 - 7 = y + 7 - 7
2 = y
The perimeter of the outer square in thiæ pattern is 8
Ron says, “The perimeter of the inner square is 4"
Do you agree with Ron? Yes
Show workings to support your answer.
Answers
Answer:
The answer is Yes .. Ron is correct
Step-by-step explanation:
This is because each side of the outer square is 2 units summing up to 8 units. So dividing each into two equal parts give 1 unit each.
Each side of the inner square divides the outer square into two making each side 1 unit.
The inner square thus takes 1 unit for it's side summing the perimeter to 4 units.

Answer:
Step-by-step explanation:
[tex]Florence \ washed \ 3\ cars \ and\ earned\ = \$ x\\\\[/tex]
[tex]Cost\ of \ washing \ one \ car = \frac{x}{3}[/tex]
[tex]Anona \ washed \ 5 \ cars \ and \ earned \ 16 \ more \ than \ Florence = x + 16[/tex]
[tex]Cost\ of \ washing \ one \ car \ by \ Anona = \frac{x +16}{5}[/tex]
[tex]\frac{x}{3} = \frac{x + 16}{5}\\[/tex] [tex][ \ cross \ multiply \ ][/tex]
[tex]5 \times x = 3 \times( x + 16)\\\\5x = 3x + 48\\\\5x - 3x = 48\\\\2x = 48\\\\x = 24[/tex]
[tex]Cost \ of \ washing \ one \car = \frac{x}{3} = \frac{24}{3} = \$ 8[/tex]
Therefore ,
Florence earned $24
Anona earned 24 + 16 = $40
Caragh Washed 4 cars, so Caragh earned = 8 x 4 = $32
