PLS Help! What is the best approximation for the perimeter of a semicircle with a diameter of 12cm? Use 3.14 to approximation pi.
A. 18.84cm
B. 30.84cm
C. 61.68cm
D. 75.36cm
PlS HELP!<3

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Answer 2
The answer is B because you have to do 12 times 3.14 to get the circumference. In order to find the perimeter, you must do the diameter times pi plus the diameter. Since it’s a semi circle you also have to divide by 2. So 12 times 3.14 divided by 2 plus 12 is 30.84 cm which is B.

Answers

Answer:

0.6

Step-by-step explanation:

We know that there are 5 counters in total. 3 white and 2 black.

So we know that 3 out of 5 are white and 2 out of 5 are black.

Therefore the chance to get white is 3/5. And for black: 2/5.

We can turn these into decimals, 3/5 = 0.6 (You can make it 6/10 to make it easier.)

And 2/5 = 0.4 (You can make it 4/10 to make it easier.)

Answering the question, you should put your cross/marker on 0.6

Answer:

0.4

Step-by-step explanation:

well if you take 35x, which is 35 times whatever, + 70, you get y. so the first one is 35(1) + 70 = 105.

so i’ll go in order

35 x 1 + 70 = 105

35 x 2 + 70 = 140

35 x 3 + 70 = 175

35 x 4 + 70 = 210.

just multiply then add 70

hope this helped

I think it would be
1 - 70
2 - 105
3 - 140
4 - 175

Step-by-step explanation:

The rate of change (which is basically the slope) can be found by dividing the rise/run or the distance up and sideways from a point on a line to another point.

60%

Step-by-step explanation:

There is a 60% decrease because 60% of 2.5 = 1.5

Which option identifies which of the two studies described has the more reliable data set and explains why?

Study 1: A survey was conducted 10 times, and the standard deviation was 7.8 percent of the mean.

Study 2: A survey was conducted 100 times, and the standard deviation was 14.5 percent of the mean.

Because the data distribution is more spread out as standard deviation increases, study 1 is more reliable.
Because the margin of error increases as sample size increases, study 1 is more reliable.
Because the data distribution is less spread out as standard deviation increases, study 2 is more reliable.
Because the margin of error decreases as sample size increases, study 2 is more reliable.

IF YOU DONT KNOW THE ANSWERS DONT ANSWER!! ANSWER ALL QUESTIONS 1-5!!

Answers

Answer:

D, A, A, B, C

Step-by-step explanation:

1.

P(odd) = 3/6 = 1/2

P(blue) = 1/5

P(odd and blue) = 1/2*1/5 = 1/10

2.

Possible outcomes are 9 as all non-zero digits. And 8 is one of them.

P(8) = 1/9

3.

Non-zero digits: 1, 2, 3, 4, 5, 6, 7, 8, 9

5 of them are odd and 4 of them are even.

One digit is discounted as can't repeat and 4 out of remaining 8 are even.

P(even) = 4/8 = 1/2

4.

Remaining marbles: 2 orange, 3 black, 4 pink. Total 9

P(pink) = 4/9

5.

Each spinner has 3 colors.

P(red or orange) = 2/3

P(both red or orange) = 2/3*2/3 = 4/9
