Answer 12

\[Error = \frac{ Measured - Actual }{ Actual }\times 100 \%\]

Answer 13

please explain more

Answer 14

The measured height is 5.12 feet. The actual height is 6 feet. Put in above equation.

Answer 15

0k so -0.88

Answer 16

-0.14666666666 is my answer

Answer 17

You need to multiply by 100% to convert it into a percent error.

Answer 18

14.67 %

Answer 19

right?

Answer 20

Correct. Well done. I neglected to say that the answer should be a positive number so you would need to take the absolute value. But you figured that out.

Answer 21

ok can you help with a few more cuz you rock!!!

Answer 22

Sure. Please post your questions.

Answer 23

Which unit rate is the lowest price per ounce?

Choice A: 22 ounces of potato chips for $3.49
Choice B: 40 ounces of potato chips for $4.79

Choice A
Choice B
The unit rates are equal.
The unit rates cannot be determined.

Answer 24

btw you are so polite

Answer 25

is it choice B?

Answer 26

Im just guessing

Answer 27

Thanks. You must calculate the price per ounce for both choices. "Price per ounce" means divide price by ounces. What do you get for price per ounce for A and for B?

Answer 28

ok for A) 0.15863636363 and for b) 0.11975

Which graph shows a proportional relationship between the number of hours of renting a canoe and the total amount spent to rent the canoe?

A graph is shown. The values on the x axis are 0, 2, 4, 6, 8, 10. The values on the y axis are 0, 18, 36, 54, 72, and 90. Points are shown on ordered pairs 0, 0 and 2, 18 and 4, 36 and 6, 48 and 8, 56. These points are connected by a line. The label on the x axis is Number of Hours. The title on the y axis is Total Amount in dollars.

Answer 37

do you get it

Answer 38

Wow! That's a lot of stuff! Basically, what you need to do is to choose the answer that describes a straight line graph. More to come...

Answer 39

D)

Answer 40

cause X axis multiplied by Y axi9

Answer 41

So the x-values are given as (0, 2, 4, 6, 8, 10) and the y-values are given as (0, 18, 36, 54, 72, 90). In order for there to be a straight line, the ordered pairs must be organized like (1st x-value, 1st y-value), (2nd x-value, 2nd y-value), etc. Do you understand what I mean?

Answer 42

csausre

Answer 43

oops sorry

Answer 44

yes

Answer 45

so X * 9 = Y

Answer 46

how about this one

Answer 47

The graph below shows the numbers of cups of strawberry juice that are mixed with different numbers of cups of lemon-lime soda to make servings of strawberry soda:

A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5. The values on the y axis are 0, 7, 14, 21, 28, 35. Points are shown on ordered pairs 0, 0 and 1, 7 and 2, 14 and 3, 21 and 4, 28. These points are connected by a line. The label on the x axis is Lemon-Lime Soda in cups. The title on the y axis is Strawberry Juice in cups.

What is the ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda?

1:28
28:1
7:1
1:7

Answer 48

Do the same thing as you did for the last one. How many cups of strawberry juice are added for every cup of soda?

Answer 49

7

Answer 50

Right. Just make sure you choose the ratio in the right order. The question asks for strawberry juice : soda.

Answer 51

Is that 1:7 or 7:1 ?

Answer 52

7:1

Answer 53

C

Answer 54

Well done!

Answer 55

ok this is a fracttion one

Answer 56

If 4 over 7 of a ton of concrete covers 7 over 8 of a bridge, how many tons of concrete are required to cover the entire bridge?

17 over 56 ton
3 over 7 ton
1 over 2 ton
32 over 49 ton

Answer 57

So 4/7 tons of concrete covers 7/8 of the bridge. In order to cover the entire bridge, you need to add another 1/7 of the amount of concrete. Not sure how well I explained that. Does it make sense?

Answer 58

no not really i am a slow learner

Answer 59

if you dont know how we can skip it

Answer 60

Not at all. Let's see if I can do better.

Answer 61

I know how to do it, just having trouble explaining it.

Answer 62

i get it use the draw and solve it as if it were your math problem just dont put the answertr

Answer 63

k

Answer 64

OK, so 7/8 of the bridge is covered. But we need the whole bridge (8/8) to be covered. So, to go from 7 parts covered to 8 parts covered, you need to add 1 more part. But how much is that 1 more part? Well, you know how much the 7 parts is, so take that amount and divide it by 7 to figure out how much 1 part is.

Answer 65

1/7

Answer 66

no 1/8 sorry

Answer 67

Mathematically,\[\frac{ 4 }{ 7 } \text{ ton} + \frac{ 1 }{ 7 }\left( \frac{ 4 }{ 7 } \text{ ton}\right)\]

Answer 68

11 1/7

Answer 69

1 & 1/7

Answer 70

Not quite. What is 1/7 x 4/7 ?

Answer 71

4/49

Answer 72

Terrific. Now you need to add 4/7 + 4/49.

Answer 73

32/49

Answer 74

oh yes!!! D)

There's your answer. Well done! Sorry for the weak explanation.

If a sprinkler waters 1 over 15 of a lawn in 1 over 3 hour, how much time will it take to water the entire lawn?

5 hours
15 hours
18 hours
45 hours

Answer 84

This one is a little easier. The whole lawn will take 15 times as long as it takes for 1/15 of the lawn. Does that make sense?

Answer 85

completely, yess

Answer 86

OK. What's 15 x 1/3 ?

Answer 87

5 easy

Answer 88

Bingo!!

The table below shows the proportional relationship between the weight of cereal, in ounces, and the number of packs of cereal:


Number of Packs
of Cereal Number of Ounces
of Cereal
2 34
3 51
4 68


What is the constant of proportionality?
9
17
34
36

Answer 91

What number (constant of proportionality) do you need to multiply the number of packs by to get the number of ounces?

Answer 92

number of packs of cerials number of ounces

2 34
3 51
4 68

Answer 93

In other words, just divide the number of ounces by the corresponding number of packs. It doesn't matter which example you use, the answer will be the same.

Answer 94

so 68, 153, 272

Answer 95

If 2 packs is 34 ounces, how many ounces is there in 1 pack?

Answer 96

17

Answer 97

oh thats my answer?
