If Cyrus knows that △ABC∼△EDC and AB¯¯¯¯¯¯¯¯∥ED¯¯¯¯¯¯¯¯, how can he prove that line m passing through AB¯¯¯¯¯¯¯¯ has the same slope as line l passing through ED¯¯¯¯¯¯¯¯?
As AB and ED are parallel, they have the same slope. This means that since lines that are colllinear with parallel segments are parallel, lines l and m are parallel.
Which factor pair of 36 has a sum that is - 20?
The factor pair of 36 whose sum is -20 are -2 and -18.
What are Factors?Factors of a number or an algebraic expression are the numbers or expressions which divides the given number evenly.
For example, 10 = 2 × 5
So we can say that 2 and 5 are factors of 10.
Let x and y be the two factors of the number 36.
Then we have,
x × y = 36
Write the factors of the number 36 as the product.
36 = 1 × 36, sum = 1 + 36 = 37
36 = -1 × -36, sum = -1 - 36 = -37
36 = 2 × 18, sum = 2 + 18 = 20
36 = -2 × -18, sum = -2 - 18 = -20
Hence the factor pair of 36 whose sum is -20 are -2 and -18.

3. Twelve people work together: four of them are managers and eight of them are office workers. Two people are chosen at random from the twelve members of the group. Calculate the probability that one is a manager and one is an office worker.
Answer:
2/9
Step-by-step explanation:
8/12 you pick an office worker
4/12 chance you pick a manager
8/12 multiplied by 4/12 is 32/144
We can simplify this to 16/72
We can simplify this to 8/36
We can simplify this to 4/18

Cannot tell
[2 marks
Answer:
No, there are less than 90 people at the party.
Step-by-step explanation:
This is because the number of women cannot go above 48 as it says "Some women leave".
-> This means that the ratio 10:11 actually states that there are 40(or less) women and 44(or less) men in the party now which is less
than 90 overall, so the answer is No.

What is the probability of spinning green and rolling an even number?
The probability of spinning green and rolling an even number will be 0.125.
The missing diagram is given below.
What is probability?The percentage of favorable events to the total number of occurrences.
The probability of spinning green will be
Toial event = 4 {R, G, B, Y}
Favorable event = 1 {G}
P(G) = 1/4
The probability of an even number on dice will be
Toial event = 6 {1, 2, 3, 4, 5, 6}
Favorable event = 3 {2, 4, 6}
P(E) = 3/6
P(E) = 1/2
Then the probability of spinning green and rolling an even number will be
P = P(G) x P(E)
P = 1/4 x 1/2
P = 0.125

Victoria holds a 5 foot long fishing pole. The fishing line extends 3 feet to the water's surface and then another 12.6 feet to a hook. How far is the fish from the hook?
The fish, the fishing pole and the water surface are all in equivalent ratio, and the fish is 21 feet from the hook
How to determine the distance between the fish and the hook?To do this, we make use of the following equivalent ratio
3 : 12.6 = 5 : x
Where x represents the distance between the fish and the hook
Express the ratio as a fraction
12.6/3 = x/5
Multiply both sides by 5
x = 5 * 12.6/3
Evaluate
x = 21
Hence, the fish is 21 feet from the hook

NEED HELPP! (05.02 MC) Using logarithmic properties, what is the solution to log11(y + 8) + log114 = log1160? Show all necessary steps.
Using logarithmic properties, the solution to the given logarithmic equation is y = 7
Solving Logarithmic equationsFrom the question, we are to determine the solution to the given equation
The given equation is
[tex]log_{11}(y+8) + log_{11}(4) = log_{11}(60)[/tex]
Applying the product law of logarithms, we get
[tex]log_{11}(y+8) \times (4) = log_{11}(60)[/tex]
This gives
[tex]log_{11}(4y+32) = log_{11}(60)[/tex]
Applying the equality law of logarithm, we get
[tex]4y + 32 = 60[/tex]
[tex]4y = 60-32[/tex]
[tex]4y =28[/tex]
∴ y = 28/4
y = 7

Step-by-step explanation:
Total paper in the hat:
2 blue + 6 red + 10 yellow + 7 purple = 25 total pieces of paper
P(AB) = 7 / 25 x 2 / 25
A is the probability of pulling a purple paper
B is the probability of pulling a blue paper
Answer:
14/625
Step-by-step explanation:
probability = favorable outcomes/total number of outcomes
First find the probability of drawing a purple piece of paper.
There are 7 pieces of purple paper.
Add all the amounts of colored paper together to get the total number of outcomes.
2 + 6 + 10 + 7 = 25
The probability of drawing purple is 7/25
Now find the probability of drawing blue. There are 2 blue pieces of paper. Since he replaces the purple paper the total stays at 25.
The probability of drawing blue is 2/25
This is a compound probability problem, so multiply the two probabilities together.
7/25 x 2/25

Hello there!
Given such a problem, you have to consider where you are beginning, the middle and you end point. Here we have T (starting point), U ( middle- not necessarily center) and V (end point).
From our question, we have;
TV = 13 and TU = 8
To get UV, we subtract TU from TV as shown:
UV = TV - TU
= (13 - 8)

Identify the degree of the polynomial 6xy2 − xy + 8 + 12y.
Answer: Three
Step-by-step explanation:
I am going to assume the first value is 6xy² and not 6xy2
6xy² − xy + 8 + 12y
The term with the highest degree is 6xy² because it has three x and y variables (x + y + y is three).
The degree of the polynomial is the same as the degree of the highest term, so your answer is:
