You have 1/2 pound of flour. You split up the flour into 3 bags so each bag weighs the same. Which of these statements is NOT true?A. Each bag has 1/3 of the flour.
B.1/2 pound is 3 times as heavy as each bag of flour.
C.Each bag has 1/3 pound of flour.
D.Each bag has 1/6 pound of flour.

Answers

Answer 1
Answer: Given:
1/2 pound of flour
split the flour into 3 bags of equal weight.

1/2 ÷ 3 

In dividing fractions, you must remember to get the reciprocal of the 2nd fraction and multiply it to the 1st fraction.

3 is the 2nd fraction. Its reciprocal is 1/3

1/2 * 1/3 = 1/6 pound of flour.

The False statement is:
C. Each bag has 1/3 pound of flour.

You should just have to multiply each coordinate by the scale factor, giving
F’ (1.5,1.25)
G’ (2.5,0.25)
H’ (0.5,0.25)

Answer:

The first option

Step-by-step explanation:

The coordinates of each point divided by 4 matched up with the ones on that answer so it's the first one. it's proportional so I think that's it.

George found that he blinked 85 times in 15 minutes. at this rate, how many seconds passed during 51 blinks

Answers

540 seconds, because this is just a proportion. You find the number of seconds in 15 mins, which is 900 seconds, then you do 85 blinks/900 seconds = 51 blinks/? seconds. You cross multiply and get 45,900=85x. You divide each by 85 to get x=540.
1 min = 60 seconds, so
15 min = 15 x 60 seconds = 900 seconds
85 blinks in 900 seconds
900/85 = 10.58 seconds per one blink (this number is rounded, but final answer is exact)
10.58 x 51 = 540 seconds for 51 blinks

Find the distance between each set of points 7,3 and 6,4

Answers

Answer:

d = √(2)

Step-by-step explanation:

Use the distance formula:  d = \sqrt{(x_(2) -x_(1) )^(2) + (y_(2) -y_(1) )^(2)}

1. Fill in the values:

d = \sqrt{(7 -6 )^(2) + (3 - 4)^(2)}

2. Subtract inside the parenthesis:

d = \sqrt{(1)^(2) + (-1 )^(2)}

3. Simplify:

d = √(1 + 1)

d = √(2)

The distance between the points is d = √(2)

What is the area of this figure.

Answers

Answer: 95cm^2

Step-by-step explanation:

Make smaller shapes then add all the areas up together at the end.

6*4 = 24cm^2

3*2 = 6cm^2

For the base of the triangle:

10+3 = 13cm^2

Area of a triangle = (b*h)/2

(13*10)/2 = 65cm^2

65cm^2 + 13cm^2 + 24cm^2 = 95cm^2

A bag contains 10 red marbles, 7 blue marbles, and 3 green marbles. You randomly select a marble from the bag, record the color, and then put that marble back in the bag. If you were to do this 200 times, how many times would you expect to pull out a blue marble?

Answers

Answer:

70

Step-by-step explanation:

We have 7 blue marbles, and 20 total marbles. As a result, if we randomly chose one marble from the bag, the probability would be (number of favorable outcomes)/(number of total outcomes) = 7/20.

This means that for each 20 trials, we would expect to pull out a blue marble 7 times, as the probability does not change over time (because we put the marbles back, there are the same amount of each marble). Over 200 trials, we can simply make it out of 200 instead of 20. We can thus multiply 7/20 by 10/10 (10/10 is equal to 1, keeping the proportions equal) to get 70/200, so we can expect 70 blue marbles out of 200.
