find the perimeter of a rectangle with a length of 4x + 2 and a width of 2x

16x + 8
10x + 4
12x + 4
8x + 2

Answers

Answer:

12x+4

Step-by-step explanation:

To find the perimeter of any shape you just have to take the sum of all the sides.

In this case you would write:

 4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)

Now you just have to simplify the expression which would give you:

12x+4 (after collecting like terms)

So the final answer will be 12x+4

4x+2+2x=6x+2 which is the same as 12x+4

Answers

Answer: For the first one, 12.5% chance

Step-by-step explanation:

The probability of flipping a coin and getting tails is 50%. Then, if you were to flip two coins and get both tails, you would have to divide the 50% by 2, which is equals to 25% of flipping two coins and getting them both tails.

So now we know...

Flipping one coin gives you 50% tails and 25% of flipping two coins and getting two tails

So now, we do it again with the third coin. We would divide the 25% by 2, which will get us to a 12.5% of getting all tails, or in fractions, 1/8

I’m not exactly sure about the other ones but I hope you found this one helpful!

1. It’s easiest to visualize if you write down all of the options that are possible when flipping a coin 3 times.
TTT
TTH
THT
THH
HHH
HHT
HTH
HTT
(i believe thats all of the options, if not adjust as needed)
but TTT is 1 out of the 8 possibilities, making the probability of getting three tails 1/8 or .125

2. There are two possibilities for getting a sum equal to three with two dice being rolled. Rolling a 1 and rolling a 2 or rolling a 2 and rolling a one.
You have 36 different combinations total, making your fraction 2/36

2/36 still needs to be simplified by dividing by two

your answer is 1/18 or .55555 repeating

3. There is no black section on the spinner so there is no way to land on a black section. The probability is 0

4. I believe this question is asking about the theoretical probability of flipping a coin, which is 1/2 or .5

5. You’ve got a theoretical probability of 3/6 or 1/2 chance to roll less than a four. If you roll the cube 24 times, you should expect to get 12 (half of 24) rolls less than four.

6. The probability of choosing a red marble is 5/30 or 1/6. The marbles are always replaced so your probability doesn’t change.

Noah pulls 60 marbles out and replaces them. 1/6 of those marbles should be red.

1/6 of 60 is 10

10 marbles should be red

7. There are 11 balls total. 5 of those are green (5/11), 3 of them are red (3/11), 2 of them are white (2/11), and 1 of the balls is orange (1/11).

The probability of choosing an orange ball (the least occurring) is 1/11 or .090909 repeating

8. Adrian has a 1/4 chance of being put in any singular section. He volunteers 20 times. We’re trying to figure out how many times he was put in either the cat or the reptile section.

If we add the probabilities of the cat and reptile assignment, you get 1/2.
1/2 of 20 is 10

Keeping the probabilities separate and adding the occurrences together at the end will give you the same answer.
1/4 of 20 is 5
Add another 1/4, which is 5+5 and it’s 10

9. Let’s label the four sections on the spinner 1, 2, 3, and 4. The outcome of the coin flip will either be heads or tails.

The combinations could be:

1 H
2 H
3 H
4 H
1 T
2 T
3 T
4 T

That totals to 8 possible outcomes.

You can multiply the two outcome numbers together to achieve the the same answer:

2(4) = 8

A scalene triangle has an angle that measures 47∘ and a second angle that measures 88∘. What is the measure of the third angle?

Answers

Answer:

45°

Step-by-step explanation:

The angles of any triangle add up to 180 degrees

add the two known angles: 47+88=135

then subtract the sum from 180 to get answer: 180-135=45

Answer:

45

Step-by-step explanation:

In a triangle the angles add up to 180 degrees. So, we can subtract 47 and 88 from 180. The result, 45, will be your final answer.

Kelly's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 4 single-shot espressos and 6 double-shot espressos. What percentage of the espressos sold were single-shot?

Answers

Answer:

40% of espresso was single-shot.

Step-by-step explanation:

To make a percentage, you need to think of a fraction first. The denominator is always 100 in a percent. If my answer is 40%, the fraction would be 40/100. If there was 6 double shots and 4 single shots, those two together would make 10. 10 x 10 is 100. So really, you just have to multiply 4 by 10 to get the percentage.
