Answer:
"similar"
Step-by-step explanation:
Congruent polygons will have corresponding sides in the ratio 1:1, but they must also have identical corresponding angles. The description of figures with identical corresponding angles (along with proportional sides) is that they are "similar".
Congruent polygons are similar polygons for which the ratio of the corresponding sides is 1:1.

Xavier created a scatterplot and a trend line for data that he collected by comparing the number of minutes he spent playing a game and the number of levels he passed.
According to the graph, which combination of minutes played and levels passed seem most likely to be possible?
A) 2 minutes played and 3 levels passed
B) 17 minutes played and 35 levels passed
C) 20 minutes played and 9 levels passed
D) 50 minutes played and 19 levels passed
Answer:
Option (C)
Step-by-step explanation:
By using regression line calculator,
Equation of the regression line will be,
y = 0.4881x - 0.85714
Here y = Levels passed
x = Number of minutes played
Now we can check every option given.
Option (A)
For x = 2 minutes,
y = 0.4881(2) - 0.85714
= 0.11906
≈ 0.1
False.
Option (B)
For x = 17 minutes,
y = 0.4881(17) - 0.85714
= 8.2971 - 0.85714
= 7.44
≈ 7th level
False.
Option (C)
For x = 20 minutes
y = 0.4881(20) - 0.85714
= 9.762 - 0.85714
= 8.9
≈ 9th level
True.
Option (D)
For x = 50 minutes,
y = 0.4881(50) - 0.85714
= 24.405 - 0.85714
= 23.54786
≈ 24th level
False.
Therefore, Option (C) will be the correct option.

Answer:
Function A has a greater slope than Function B.
Step-by-step explanation:
An easy way to solve this would be to graph function B and see which line is steeper. The steeper line always has greater slope.
Answer:
A
Step-by-step explanation:
its function would be y=4x+2
A cleaning company charged $125 to clean a 2500 square foot house. The same company charged $146 to clean a 3200 square foot house. Write an equation in slope-interceptiom to represent the total cost, y, to clean a house with x square feet. Then, find the total cost to clean a house that is 4500 square feet.
Answer:
The cost is y = $185
Step-by-step explanation:
Let us have points spelt out here
(2500,125) and (3200,146)
The general form of a straight line equation is;
y = mx + b
where m is slope
So to calculate the slope in this case, we have
m = (146-125)/(3200-2500)
m = 21/700 = 0.03
So we have the equation as
y = 0.03x + b
To get b, we use any of the two points
Let us use (2500,125)
So we have
125 = 0.03(2500) + b
125 = 75 + b
b = 125-75
b = 50
So the complete equation of the line is;
y = 0.03x + 50
So here, we want to find the cost of a house with 4500 square feet
simply substitute 4,500 for x
y = 0.03(4500) + 50
y = 135 + 50
y = $185

The formula for area of a triangle is given by: A=bh/2 Rearrange the formula to solve for b
Answer:
b = 2A
h
Step-by-step explanation:
A=bh/2
2A = bh
b = 2A
h
Answer:
b=(2a)/h
Step-by-step explanation:
Multiply both sides by 2
2A=bh
Divide both sides by h
(2a)/h=b

The position of an object in a video game is represented by an ordered pair. The coordinates of the ordered pair give the
number of pixels horizontally and vertically from the origin. Use this scenario for Exercise.
a. Suppose that player A is located at (36, 315) and player B is located at (410, 53). How far apart are the players? Round to
the nearest pixel
b. If the two players move directly toward each other at the same speed, where will they meet?
c. If player A moves three times faster than player B, where will they meet? Round to the nearest pixel.
Answer:
a. 457 pixels b. 229 pixels c. 114 pixels
Step-by-step explanation:
a. Using d = √[(x₂ - x₁)² + (y₂ - y₁)²] to find the distance apart of the coordinates (x₁, y₁) and (x₂, y₂) where (x₁, y₁) = (36, 315) and (x₂, y₂) = (410, 53).
So, d = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(410 - 36)² + (53 - 315)²]
= √[374² + 262²]
= √[139,876 + 68,644]
= √208,520
= 456.64
= 457 pixels to the nearest pixel.
b. Since the players are d' distance apart, and moving at a same speed of v, if they approach each other, they meet at time t. So player A covers a distance of d = vt. For them to meet, player B approaches and covers a distance of d = d' - vt. So they meet when vt = d' - vt.
Solving this, we have
vt = d' - vt
vt + vt = d'
2vt = d'
t = d'/2v
Substituting t into d = vt, we have
d = vt
= v(d'/2v)
= d'/2
= 457/2
= 228.5
≅ 229 pixels to the nearest pixel
c. Since the players are d' distance apart, and player A moves at a speed three times that of player B, if player B moves with speed v, then player A moves with speed 3v, as they approach each other, they meet at time t. So player A covers a distance of d = 3vt. For them to meet, player B approaches and covers a distance of d = d' - vt. So they meet when 3vt = d' - vt.
Solving this, we have
3vt = d' - vt
3vt + vt = d'
4vt = d'
t = d'/4v
Substituting t into d = vt, we have
d = vt
= v(d'/4v)
= d'/4
= 457/4
= 114.25
≅ 114 pixels to the nearest pixel

Find the area of the figure
Answer:
45 I'm pretty sure. so it 45
Answer:
The figure is 5.5in^2.
Step-by-step explanation:
To find the area of the triangle portion, we will use the formula for area of a triangle, [tex]\frac{bh}{2}[/tex], where b = base and h = height.
So lets find our variables,
b = 3
h = 3
So we can plug that into our equation and find the area,
3 · 3 = 9 and 9 ÷ 2 = 4.5
So the area of the triangle is 4.5in^2
To find the area of the square portion, we will use the formula for the area of a square or rectangle, l · w, where l = length and w = width
So lets find our variables,
l = 1
w = 1
So 1 · 1 = 1in^2
To find the total area we will add the areas of the two components together,
4.5 + 1 = 5.5in^2
So the area of the total figure is 5.5in^2.

Martin drinks 1/4 of a litre of juice each day.
Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.
Martin buys enough juice to last for 2 weeks (14 days).
What is the lowest price Martin can pay for this juice?
Given :
Martin drinks 1/4 of a litre of juice each day.
Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.
To Find :
Martin buys enough juice to last for 2 weeks (14 days).
What is the lowest price Martin can pay for this juice.
Solution :
Amount of litre used in 14 days is :
V = 14× ( 1/4 )
V = 3.5 liter
Lowest price to pay is :
P = 2 × Cost of one 2 L carton
P = £(2 × 3.60)
P = £7.2
The lowest price Martin can pay for this juice is £7.2 .
Hence, this is the required solution.

The formula for throwing a baseball in the air is represented by the attached function, where h represents the height of the ball in inches, and t represents time. How high is the baseball after 3 and a half seconds?
h(t)=-3t^2+12t+40
Answer:
45.25 in
Step-by-step explanation:
To solve this question you would plug 7/2 or 3.5 in for t and solve for h(t).
h(t)=-3(7/2)^2+12(7/2)+40
=-3(49/4)+(84/2)+40
=(-147/4)+42+40
=-36.75+42+40
=45.25 in
