when m and I are cut by transversal n. if m<3=67° , determine m<6.
Answer:
113°Step-by-step explanation:
Angles 3 and 6 are consecutive interior angles
As per definition, consecutive internal angles add to 180°
m∠3 = 67° ⇒ m∠6 = 180° - 67° = 113°PLS HELPPPP IM BEING TIMED

Are the ratios 5:20 and 1:2 equivalent?
Hey there!
Question reads….
“Are the ratios 5:20 and 1:2 equivalent?”
Let’s find out if they are or not!
5:20
= 5 ÷ 5 : 20 ÷ 5
= 1 : 4
So, therefore, your answer is: NO because 5:20 = 1:4 NOT 1:2
Good luck on your assignment & enjoy your day!

Which equation represents a line parallel to 2x+y=-2?
A. y=-2x+3
B. x+y=5
C. y-x=-1
D. y-2x=3
Answer:
Option A
Step-by-step explanation:
To find the answer we need to graph the following equations to see which equation is parallel to the given equation 2x + y = -2x. Your answer is option A or "y = -2x + 3." One of the biggest rules when trying to find out if the two lines are parallel to each other is seeing if the two lines intercept. In this case if you graph all the following options, the only line that does not intercept the first line 2x + y = -2 is the option A, which means it's your answer.
Hope this helps.
imagine that you write each letter of the word california on individual cards. you shuffle them, turn them facedown on a table, and trn over the top card. what is the probability of turning over an A?
Answer:
Let's find how many letters California has first, c-a-l-i-f-o-r-n-i-a has 10 letters.
Now let's find how many letter A's are in the word California, California has two a's in the word.
So there are 2 cards out of 10 that could possibly be selected as the letter A.
Your probability is:-
2/10 which simplifies to 1/5, if you wanted to make this a percentage as well;
1/5 * x/100
solve for x;
20%
The required probability of turning over an A is given as 20% or 0.2.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
California = C, a, l, i, f, o, r, n, i, a = 10 letters
So,
Number of card = 10
Now,
there are two a's in the card deck
So the probability of turning over an A,
= 2 / 10
= 0.2 or 20%
Thus, the required probability of turning over an A is given as 20% or 0.2.

a bag contains 11 counters, five of the counters are white .a counter is taken out of the bag at random and not replaced. a second counter is taken out of the bag at random.calculate the probability that only one of the counters are white
Answer:
6/11
Step-by-step explanation:
5 of the counters are white that are taken out of the bag. That means if one more was taken out if the bag after that was the only white counter left then we can conclude that since there are 11 counters in the bag and 6 are white then, the probability of picking a white counter would be 6/11.
Have a great rest of your day
#TheWizzer
Answer:
P(of picking one of the white counters )= 8/11
Step-by-step explanation:
Firstly you need to identify the counters
White counters = 5
Unknown= 6
Total outcome = 11
With the aid of a tree diagram and following the condition of not replaced we go on and compute our findings
Help Math, Need someone to help with vertical angles
DOWN BELOW
Answer:
x = 25°
Step-by-step explanation:
The angles are equal and opposite. This means that if the top angle is 150°, then the angle at the bottom must be 150° too. However, it is currently 2x° + 100°, which turns it into an equation. So far we have 100° as a known angle, so we subtract that from 150° to get the value of 2x.
2x° = 50
Now we divide 50 by 2, and that gives us 25°.
x = 25°

A. 75.6 in³
Step-by-step explanation:
The volume of a rectangular prism is V = Bh, where B = area of the base and h = height. We're given the dimensions of the base as 4.2 and 3, and the height as 6.
4.2 × 3 = 12.612.6 × 6 = 75.6 cubic inchesHave a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
A. 75.6 in³
Step-by-step explanation:
Given :-
Base area = 4.2 in x 3 in
Height = 6 in
To find :-
Volume
Formula required :-
Volume = length x breadth x height
Volume = base area x height
Solving :-
V = 4.2 x 3 x 6
V = 12.6 x 6
V = 75.6 in³
Solution :-
A. 75.6 in³

What is the slope of the line below?
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The slope could be determined by plugging in what you know into here....
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
then plug in what you know...
[tex](1,-2)\\(3,2)\\y_{2} =-2\\y_{1} =2\\x_{2} =1\\x_{1} =3[/tex]
[tex]m=\frac{-2-2}{1-3} =\frac{-4}{-2} =2[/tex]
So the slope is 2.
