In the past year Diane watched 22 movies that she thought were very good. She watched 40 movies over the whole year. Of the movies she watched, what percentage did she rate as very good?

Answers

Answer 1

Answer:

55%

Step-by-step explanation:

For percentages, you need to divide the part by the whole, then multiply by 100.

In this case, [tex]\frac{22}{40}[/tex] = 0.55.

Then multiply by 100 to get a percentage: 0.55 x 100 = 55%

Answer 2

Answer:

55%

Step-by-step explanation:

Total number of movies= 40

Number of movies rated very good= 22

Percentage of movies rated very good= 22/40*100%

= 55%

Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1

Answers

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

Answer : -1 < -0.25,

write 1 1/2 and 2 1/4 on the number line below.

Answers

Answer:

So lets convert the fractions to improper:

3/2 and 9/4

And for it to be easier to plot, make them decimals (divide):

1.5 and 2.25

The step here is 0.125 (1/8 (the amount of lines between a number))

Plot:

1.5, is 1 1/2 and 2.25 is 2 1/4 on the number line..

Lets convert the fractions to improper:

1 1/2 = 3/2 = 1.5.

2 1/4 = 9/4 = 2.25.

3/2 and 9/4

And for it to be easier to plot, make them decimals (divide):

1.5 and 2.25

Therefore, 1.5, is 1 1/2 and 2.25 is 2 1/4 on the number line.

Step-by-step explanation:

Let's just go through it.

No parallel sides A B C (if you believe the diagram) D F

Not regular (and no parallel sides) (if you believe the diagram) B C D F

No Lines of symmetry (that means that if you put a mirror on a line of symmetry) what you see as an image will be the same as what there is in front of the mirror. C D F

Has a reflex angle. (Just to remind you, it is an angle greater that 180 but less than 360

That lets out everybody but D.

Answer: D

Step-by-step explanation:

1. C and G have one set of parallel sides, and E, H, and I have two sets of parallel sides so they can be ruled out.

2. Regular shapes have sides that are all the same length and angles that all measure the same. A can be ruled out in addition to I which was already ruled out.

3. B can be ruled out now.

4. The only one with a reflex angle (greater than 180 degrees) is D.
