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.
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°

It costs $10 to enter a petting zoo. Each cup of food to feed the animals is $2. If you have $14, write and solve an equation to determine how many cups of food you can buy.
PLEASE WRITE AN EQUATION
Answer:
5 cups
Step-by-step explanation:
To do this simply, we can just count up how many cups we can buy.
starting balance=
$12.50
after cup 1=
12.5−2.5=$10.00
after cup 2=
10−2.5=$7.50
after cup 3=
7.5−2.5=$5.00
after cup 4=
5−2.5=$2.50
after cup 5=
2.5−2.5=$0.00
From this, we can see that after buying the 5th
cup, the buyer is out of money, so that means that you can buy
5 cups of food to feed the animals before running out of money.
The number of cups is 2 cups
The equation is y = 2x + 10 where the slope of the equation x is the number of cups and y is the total amount
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the total number of cups be = x
The total amount y = $ 14
The cost of entering the zoo = $ 10
The cost of of feeding the animals per cup = $ 2
So , the equation will be
Total amount y = cost of entering the zoo + ( total number of cups x cost of of feeding the animals per cup )
Substituting the values in the equation , we get
y = 2x + 10 be equation (1)
On simplifying the equation , we get
14 = 2x + 10
Subtracting 10 on both sides of the equation , we get
2x = 4
Divide by 2 on both sides of the equation , we get
x = 2 cups
Therefore , the value of x is 2 cups
Hence , the number of cups is 2 cups

50 POINTS if p=(-2,-1) and Q=(-6,-3) are the endpoints of the diameter of a circle, find the equation of the circle
Answer:
(x+4)^2 + (y+2)^2 = 5
Explanation:
Using the midpoint formula, we find that the center of the circle is (-4, -2). We also calculate using the distance formula that between the two points is [tex]\sqrt{2\\0}[/tex]or [tex]2\sqrt{5\\\\}[/tex].
Because we found the diameter, to find the radius we divide by two, getting [tex]\sqrt{5\\\\}[/tex].
Now that we have the center, (-4, -2), and the distance from the center to the radius, we can put the information into the circle equation:
(x-h)^2 + (y-k)^2 = r^2
This becomes:
(x+4)^2 + (y+2)^2 = 5
Answer:
-4 , -2 , 5Step-by-step explanation:
(x-(-4))^2+(y-(-2))^2=5
since 2 negatives equal a positive, - -4 = +4
same thing for -2
(x+4)^2+(y+2)^2=5

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.

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

What are similar triangles?
If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the triangle be ABC and ADE
The triangles ΔABC ≅ ΔADE
Now , Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
So , the ratio of the sides will be
AD / AB = AE / AC
Substituting the values in the equation , we get
14 / 20 = x / 33
Multiply by 33 on both sides of the equation , we get
The value of x = ( 14 x 33 ) / 20
The value of x = 462 / 20
The value of x = 23.1
Therefore , the value of x is 23.1
Hence , The value of x from the triangle is x = 22.1

A local pizza shop has a membership program for frequent buyers. The membership costs $5 per month and members get a discounted price of $1.50 per slice of pizza. Nasim purchased a membership to this pizza shop. How much would Nasim have to pay the pizza shop if he bought 20 slices of pizza this month? What would be the monthly cost for xx slices of pizza?
Answer: Nazim have to pay $35 for 20 slices of pizza.
Monthly cost for x slices = 5+1.5x
Step-by-step explanation:
Let x = number of slices
As per given,
Total monthly cost for x slices = (membership cost) +(discounted price) ×(x)
i.e. Total monthly cost for x slices = 5+1.5x
If x=20
Then, Nazim have to pay = 5+1.5(20)
= 5+30= $35
i..e Nazim have to pay $35 for 20 slices of pizza.
Monthly cost for x slices = 5+1.5x
