Use x to represent the first two angles. If the third angle is 3 times as large as the first, it can be represented as 3x. So, your angles are x, x, and 3x. These need to all add to 180 degrees, since it’s a triangle.
x + x + 3x = 180 —> Simplify the left side.
5x = 180 —> Divide by 5.
x = 36
So the first two angles are 36 degrees, and the third angle is 3 times that, which is 108 degrees.
1.A to find the answer, round $5820 to $6000. Then round $28 to $30. Each curtain would cost an estimate of $200.

Answer:
I'm not sure if you mean each person has a car for 2 weeks and travels 500 miles each but if so the rental cost is $2,940.
If it is just one car for all 3 people the rental cost is $980
Step-by-step explanation:
renatl cost = r
weeks = w
miles = m
the equation would be r = $240w + $1m
and if there are 3 people you mulitply the answer by 3

Answer:
You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.
The probability of selecting a red marble the first time is 1313.
(This is because 4 out of 12 marbles are red and412412 reduces to 1313.
The probability of selecting a red marble the second time is 1313.
The marble selections are independent and you can multiply the two probabilities to get the following:
probability of getting 2 reds = (13)2(13)2
=19=19.
So the probability of getting two reds is 1919.
