Graph ∆KLM with vertices K(2,2), L(0,- 1), and M(-3,2). Graph ∆K'L'M' with a scale factor of 2. What are the coordinates of the new vertices?
Answer:
The coordinates of the new vertices are:
K'(4,4), L'(0,- 2), and M'(-6,4).
Step-by-step explanation:
In order to dilate a shape by 2, you can simply multiply the coordinates of the orignal triangle each by 2 to find the new coordinates of the new vertices.
K(2,2), L(0,- 1), and M(-3,2)
K'(2*2,2*2), L'(0*2,- 1*2), and M'(-3*2,2*2).
Now become...
K'(4,4), L'(0,- 2), and M'(-6,4).
You can now graph ∆K'L'M' using these coordinates.
In how many different ways can four students stand in a straight line if two of the students refuse to stand next to each other?
Hey there! I'm happy to help!
Let's look at each spot in the line from left to right and see how many choices they are.
In spot 1, we have 4 choices. Let's say that we choose the student who doesn't want to stand next to to the other student. This means that in the next slot, there are only 2 choices because he cannot stand by the other student. Now when we move to spot number three, there are only two choices left, and then there is 1.
4×2×2×1=16
So, there are 16 different ways the students can stand in a straight line if two of the students refuse to stand next to each other.

Answer:
The Super Sleuths did not find all 100 ounces of gold, they only found 92 2/3 ounces, so they have 7 1/3 more ounces of gold to find left.
Step-by-step explanation:
Pirate hid 100 ounces of gold.
1. 19 1/2 ounces of gold was found.
2. 26 2/3 more ounces of gold was found.
3. 5 1/6 more ounces of gold was found.
4. 48 1/3 more ounces of gold was found.
First, we need to add up all of the ounces of gold that was found.
12 1/2 + 26 2/3 = 39 1/6
5 1/6 + 48 1/3 = 53 1/2
53 1/2 + 39 1/6 = 92 2/3
100 - 92 2/3 = 7 1/3

State which theorem you can use to show that the quadrilateral is a parallelogram.
Answer:
We can use the theorem ''Parallelogram Diagonals Converse'' to show that the quadrilateral is a parallelogram.
Step-by-step explanation:
We know that the diagonals of any parallelogram bisect each other, each diagonal cutting the other into two equal parts.
In other words, according to Parallelogram Diagonals Theorem Converse, the figure will be a parallelogram if the diagonals of the quadrilateral figure cut (bisect) each other. It is basically the
From the given Parallelogram, it is clear that the diagonals bisect each other, each diagonal cutting the other into two equal parts with the length 3 units.
Therefore, we can use the theorem ''Parallelogram Diagonals Converse'' to show that the quadrilateral is a parallelogram.

Complete the chart below for this word problem.
Canadian Tire is selling coffee mugs. A coffee mug costs $5 and each day the price increases by $2. (The algebraic equation for this: 5+2x)
Fill out the variable chart below for graphing. The days are on the x-axis and the cost is on the y-axis.
Answer:
The y-values from top to bottom are;
3, 5 , 7, 9, 11, 13, 15
Step-by-step explanation:
Here, we want to fill out the given table
Let us have an equation linking x and y
From the question, we can have this as;
y = 5 + 2x
When x = -1
y = 5 + 2(-1) = 3
when x = 0
y = 5 + 2(0) = 5
when x = 1
we simply add 2 to the previous
= 5 + 2 = 7
when x = 2
= 7 + 2 = 9
when x = 3
= 9 + 2 = 11
when x = 4
= 11 + 2 = 13
when x = 5
y = 13 + 2 = 15

(A) 5 × 4 = 20 and 5 × 40 = 200 (B) 5 × 5 = 25 and 5 × 50 = 250 (C) 5 × 7 = 35 and 5 × 70 = 350 (D) 5 × 8 = 40 and 5 × 80 = 400 Part B Use the answer from Part A to estimate the quotient. Enter your answer in the box. The quotient of 323 ÷ 5 is about .
Answer:
30
Step-by-step explanation:
From the given information; we are to estimate 323 ÷ 5
The first thing to do is to round each integer to the nearest whole tens
i.e 323 is approximated to 300
5 is approximated to 10
∴
The estimated quotient of 300 ÷ 10
= 30
From part A, there is no equation that shows us how to use multiplication to estimate the quotient.

ab =
a · b =
Answer:
First = 49/4
Second = 539
Step-by-step explanation:
The dot product is 539, and the scalar projection of a onto b is 49/4
What is a Vector?Vector is a quantity that has both magnitude and direction.
The scalar projection of a onto b is given by
[tex]\dfrac {a.b}{|b|}[/tex]
a.b = |a| |b| cos[tex]\rm \theta[/tex]
a.b = 21 *44 *(7/12)
a.b = 539
The dot product of a and b is 539.
The scalar projection is
= 539 / 44
= 49/4
Therefore, the dot product is 539, and the scalar projection of a onto b is 49/4.

Answer:
a) The percent of their games the hockey team won is 60%
b) The percent of their games the hockey team lost is 37% to the nearest percent
c) The percent of their games the hockey team tied is 3% to the nearest percent
Step-by-step explanation:
In any game, there are 3 situations
WinTie LoseThe sum of the three situations is the total number of playing that game
∵ The hockey team won 72 out of 120 games and tied 4
∴ The number of winning games = 72
∴ The number of tying games = 4
∴ The number of total games = 120
→ Find the number of losing games
∵ Win + ty + lose = total games
∴ 72 + 4 + lose = 120
∴ 76 + lose = 120
→ Subtract 76 from both sides
∴ lose = 44
∴ The number of losing games = 44
Now let answer the questions
a)
∵ P%(win) = (winning ÷ total) × 100%
∴ P%(win) = (72 ÷ 120) × 100%
∴ P%(win) = 60%
The percent of their games the hockey team won is 60%
b)
∵ P%(lose) = (losing ÷ total) × 100%
∴ P%(lose) = (44 ÷ 120) × 100%
∴ P%(lose) = 36.66667% = 37% to the nearest percent
The percent of their games the hockey team lost is 37% to the nearest percent
c)
∵ P%(tie) = (tying ÷ total) × 100%
∴ P%(tie) = (4 ÷ 120) × 100%
∴ P%(tie) = 3.333333% = 3% to the nearest percent
The percent of their games the hockey team tied is 3% to the nearest percent
