Answer:
1. To dilate something in the coordinate plane, multiply each coordinate by the scale factor. This is called mapping. For any dilation the mapping will be \begin{align*}(x, y) \rightarrow (kx, ky)\end{align*}. In this Concept, the center of dilation will always be the origin, unless otherwise stated.
2. When using State Plane coordinates the scale factors, also known as the K factors, are ratios that can be used as multipliers to convert ellipsoidal lengths, also known as geodetic distances, to lengths on the map projection surface, also known as grid distances, and vice versa.
3.Similar figures have the same shape (but not necessarily the same size) and the following properties: Corresponding sides are proportional. That is, the ratios of the corresponding sides are equal. Corresponding angles are equal.

Answer:
Ok so I’m stuck with this question too But I got the top part.
p=1/6
q=2/6
r=3/6
s=3/6
A) The probabilities placed at P, Q, R and S on the tree diagram are;
P = 1/6; Q = 1/3; R = 1/4; S = 1/4
B) The probabilities of her winning or losing is;
Probability that she will win = 5/12
Probability that she will lose = 7/12
A) From the given tree diagram, we can see that;At point P; Only 1 is rolled.
Since there are 6 possible numbers, then Probability at P = 1/6
At point Q; either 2 or 3 can be rolled.
Since there are 6 possible numbers, then Probability at Q = 2/6 = 1/3
At point R; 4,5, or 6 can be rolled on first roll.
Thus, Probability on first roll = 3/6
At R on second roll if she gets even, probability on second roll = 3/6
At S on second roll if she gets odd, probability on second roll = 3/6
Thus;
Overall probability at R = 3/6 × 3/6 = 1/4
Overall probability at S = 3/6 × 3/6 = 1/4
B) Probability that she will win are the probabilities at P and R.Thus, probability that she will win = 1/6 + 1/4 = 5/12
Probability that she will lose are the probabilities at Q and S.
Probability that she will lose = 1/3 + 1/4 = 7/12

A rectangular water tank is 80 m long, 50 m wide and 60 m height. If the
depth of water in the tank is 45 m, find the volume of water required to
completely fill the tank?*
A)240,000cm3
B)60,000cm3
C)180,000cm3
D)120,000cm3
Answer: 2
Step-by-step explanation:
80 x 50 x 60 is volume of tank
240000
Water is already filled to 45 so volume up to that is
80x 50 x 45 = 180000
Subtract to find the difference needed to fill tank
240000 - 180000 = 60000
The volume of water to completely fill the tank is A) 240,000cm³.
What is volume?Volume is defined as the amount of three-dimensional space occupied by some close object.
We know the volume of a cuboid is (Height×Width×Length).
Given a rectangular water tank is 80m long, 50m wide and 60m in height and the depth of the water is 45m.
To obtain the volume of water we have to take 45m as the height or we can think of the height of the tank is 60m but water can only be filled up to 45m.
∴ The volume of the water is (80×50×45) m³.
= 180,000 m³.

In which number is the value of the seven equal
to (7x1/
1,000)?
A 36.074
B 7,256.05
C 64.387
D 769.21
Answer:
It would be C, 64.387
Step-by-step explanation:
First, you have to solve 7x1/1000. This equal to 7/1000 which should be converted into decimal form (since all the answers are in decimal form). 7/1000 is 0.007 in decimal form.
It is 0.007 since in 7/1000, the denominator is 1000, making 7 in the thousandths place (the 3rd digit to the right of the decimal point).
The only number that contains 0.007 is the 3rd one, making it your answer.

Step-by-step explanation:
The 90-degree angle and "x" form a straight line. The degree measurement of a straight line is 180. That means that if one adds 90 and "x", they will get 180, and therefore, x equals 90.

Step-by-step explanation:
From the question question we are told that
Location A => t=0 => 0
Location C => t=2 => 40

Location B => t=1 => 160
Total time 3min

Solve for x if y = 3 in the equation 2x + 3y = 12 *
Answer:
x = 3/2 or 1.5
Step-by-step explanation:
y = 3 in the equation 2x + 3y = 12
Substitute 3 in for y.
2x + 3(3) = 12
Multiply.
2x + 9 = 12
Subtract 9 from both sides.
2x + 9 - 9 = 12 - 9
2x = 3
Divide both sides by 2.
2x ÷ 2 = x
3 ÷ 2 = 3/2 or 1.5
x = 1.5
Answer:
X = 1.5
Step-by-step explanation:
So we know that Y = 3 and 3 x 3 = 9, then we need to get the difference of 9 to 12
12 - 9 = 3
we now know that x will equal 3, so 2 x 1.5 = 3, and 3 + 9 = 12
(Full equation)
2 x 1.5 + 3 x 3 = 12

Dan rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 3.
Answer:
1 / 36
Step-by-step explanation:
A roll of 2 fair dice :
Total number of possible outcomes = n² ; n = number of faces in a dice = 6² = 36
Probability = required outcome / Total possible outcomes
Required outcome = total less than 3 = 1 (from sample space provided)
Hence,
P(total less than 3) = 1/36
