Question

Problem is the very last post.

Answer 1

1/8 of the original.

Answer 2

Each dimension is 1/2 it's original so the volume is (1/2)(1/2)(1/2) the original which is 1/8.

Answer 3

Thank you. I will have more questions, do you mind helping me? There is like 20?

Answer 4

Sure.

Answer 5

Alright, thank you. :) I will post them if I need additional help.

Answer 6

Ok.

Answer 7

Which is true based on the circle graph if 400 college students were surveyed?

0-2 hrs = 20%
2-4 hrs = 40%
4-6 hrs = 30%
6 or higher = 10%

*This is all represented in a circle graph*

a)More than half of the students spend an average of at least 2 hours per week on homework for one class.
b) 50 students spend an average of four hours per week or less on homework for one class.
c) More than one-third of the students spend an average of between 4 and 6 hours per week on homework for one class.
d) 20 students spend an average of more than six hours per week on homework for one class.

Answer 8

a

Answer 9

At least 2 hours includes 2-4, 4-6 and 6+ and that's 80% of the students thus more than half.

Answer 10

How'd you get that answer?

Answer 11

Oh, nevermind. Thank you. c:

Answer 12

That's alright, I was assuming that the survey was, How many hours do you spend on homework for one class per week?

Answer 13

Yes it was, I assumed I could have not put the title in, it didn't seem that much important.

Which of these has the greatest area?

a)rhombus with side lengths: 9 inches, height: 4 inches
b)triangle with base length: 8 inches, height: 3 inches
c)circle with radius: 2 inches
d) trapezoid with base lengths: 5 inches and 3 inches, height: 4 inches

Answer 14

For the other answers, b cannot be certain as there isn't an answer for 4 only 4-6 or 2-4. c cannot be right as 30% is less than one third and d is wrong because 10% of 400 is not 20.

Answer 15

Oh, okay. I get it now. Thanks:)

Answer 16

Area of the rhombus is 9x4=26. Area of the triangle is (8x3)/2=12. Area of the circle is pi2^2= 4pi = roughly 12. Area of the trapezoid is ((5+3)x4)/2)= 16. Biggest area is A.

Answer 17

THANKS:) I had real trouble on that one, for a long time. >.<

I decided to screen pellet this one ^

Answer 18

o.o I meant screen shot.

Answer 19

I must have typed a curse word and it changed. xD

Answer 20

Each one has a probability of 0.1 or 10%. If you want to find the probability of multiple ones, just multiply the probabilities together. A and A would be 10%x10% which is 1%. M and E and T is 10%x10%x10% which is 0.1%. Before J and after J is 40% (there are 4 before J) x 30% (there are 3 after R) which is 12%. There are 5 vowels and 5 consonants so 50% x 50% which is 25%.

Answer 21

lol screen pellet

Answer 22

*after R.

Answer 23

If you convert the percentages to fractions or decimals it is easier. So each one has a 1/10 probability. So A and A is 1/100 which is 1%. E and M and T is 1/1000 which is 0.1%. Before J and after R is 4/10x3/10 which is 12/100 and 12%. Vowel and Consenant is 5/10 x 5/10 which is 25/100 and 25%.

Answer 24

That's much easier, for me. The second way I understood much better.

Here's another one. I'm sorry I feel like I'm a burden.. :c

Answer 25

And @Kainui Ikr, isn't that funny.. I was like laughing about it. ;p

Answer 26

Surface area of square pyramid is 6x6 + 4((6x10)/2) = 156

Answer 27

The other square pyramide is 5x5 + 4((5x11)/2) = 135

Answer 28

Cone is pi4^2 + pi4x8 = 40pi.

Answer 29

Wait, 48 pi.

Answer 30

And how does that help me? o.o There's no answer with 48 pi.. D:

Answer 31

The other cone is pi6^2 + pi6x4 = 60 pi

Answer 32

pi is 3.14, you can multiply 48 by 3.14

Answer 33

151 probably

Answer 34

60 pi will probably be 188

Answer 35

Area of square pyramids are base^2 + 4((base x slant height)/2)

Answer 36

So..? Is D= 188 which is A?

Answer 37

Area of cone is \[\pi r ^{2} + \pi r s\]

Answer 38

156

Answer 39

Number 1 is 156

Answer 40

Number 2 is 151

Answer 41

Number 3 is 135

Answer 42

Number 4 is 188

Okay thanks, got it now. :)
Help me with this one? ^

Answer 44

1 is B

Answer 45

2 is C

Answer 46

3 is A

Answer 47

4 is D

Answer 48

Translation just means move around so you just take 5 from the x values and add 2 to the y values

Answer 49

Reflection in x axis means all the y values become negative

Answer 50

Reflection in y axis means all the x values become negative

Answer 51

Dilation by scale factor 5 means multiply all the x and y values by 5

Answer 52

Lydia received a parking ticket because she parked 10 feet from a fire hydrant. She had estimated her distance from the fire hydrant as being the minimum allowable distance, which is 15 feet. What was her percent error?

Answer 53

Yeah, I knew that. I just always screwed up the part when you add in the numbers and start multiplying. o.o

Answer 54

5/15 x 100

Answer 55

So was 5 off what was right so it's 5/15 and multiply by 100 to get a percentage

Answer 56

@iAmCool

Answer 57

Sorry, I had to go. :c
So the answer is 15%?
