The length of the Titanic was 882 feet. Porter's history class is building a model of the Titanic. The model is 1/100 of the actual length of the ship. How long is the model?
Answers
Answer:
8.82 feet
Step-by-step explanation:
Explanation:
Let's set up the ratio. We know that the actual length of the ship was 882 feet and we want to know how long the model will be. We also have a ratio of 1 model length to every 100 actual length. So we can write this as:
Model length
Ship length
=
1 Model length
100 actual length
And we can drop in some numbers (I'll also put in the variable
x
to represent the length of the ship model):
x
882
=
1
100
Let's cross multiply to solve for x:
100

Answers
Answer:
x = 63
Step-by-step explanation:
Step 1: Multiply both sides by 7/5.
\(45 *\frac{7}{5}=\frac{5}{7}x*\frac{7}{5}\) \(63 = x\)Step 2: Check if solution is correct.
\(45 = \frac{5}{7}(63)\) \(45 = 5 * 9\) \(45 = 45\)Therefore, x = 63.
x = 63
Step-by-step explanation:45 = 5/7x
=> 9 = x/7
=> x = 63.

A cage has canaries and parakeets in the ratio 4:7. another cage has cockatiels and parakeets in the ratio 5:8. are the ratios of birds in the two cages equivalent?
Answers
Answer: No
Step-by-step explanation:
think of 4:7 as a fraction. that would be 4/7 right? so compare that to 5:8 as a fraction- 5/8. Are these fractions the same? the answer is no.
Answer: No.
Step-by-step explanation: In this situation, you should be able to multiply the lesser ratio by a certain number and it should be equivalent with the bigger one.
Example:
1:1
2:2
For this example, you would want to multiply 1:1 by Q. Q will be our variable here. So, 1 times q equals 2. Q would be equivalent to 2, now multiply both the 1's in 1:1.
The two ratios also don't hold the same types of birds, so it cannot be equivalent whatsoever.
Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

Which part of this box plot includes about 50% of the data?
A.
There is not enough information to tell.
B.
The box, from 44 to 52
C.
The lower whisker, from 34 to 44
D.
The upper whisker, from 52 to 59
Answers
Answer:
B
Step-by-step explanation: The box represents the middle 50% of the data, with the bottom and top of the box representing the first and third quartiles, respectively. The line inside the box represents the median.
The whiskers extend from the box to show the range of the data, excluding outliers. Outliers are typically shown as individual points outside the whiskers.
Based on this information, we can see that the box in the box plot represents the middle 50% of the data. Therefore, the answer is B. The box, from 44 to 52, includes about 50% of the data.

At the store you want to buy a bunch of 3d printed Christmas gifts for your family. Each large tree costs $4.50 , and each small tree costs $2.25, If you buy 4 large trees, and can spend a total of $50. Write and solve an inequality for number of small trees (s) you can buy
Answers
We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.
If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.
The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.
To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:
s * $2.25 = $32
s = $32 / $2.25
s = 14.22
Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.
Answer:
If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

Answers
Answer:
C
Step-by-step explanation:
we can convert 18 percent to .18 and then we can multiply 1.18 by 14000 to get our answer. if you don't do the extra 1 before the decimal you will get the 18 percent then have to add it to 14000 so adding the 1 before doesn't affect anything, it just makes it easier, without it it would be a two step problem (adding the .18 to 14,000).

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Answer:
See Below
Step-by-step explanation:
Lets look at our numbers:
The balloon is at 1000 feet.
The balloon drops at a constant speed of -4 1/2 per second.
How long will it take to get to 215ft, in seconds, s.
Lets see, if you were to subtract 1000-215, you will get 785.
The balloon needs to drop 785ft to get to 215ft above the ground.
The question asks how long will it take to get below 215ft.
Lets do the math for the descending feet. We calculated that it takes 785ft to hit 215ft above the ground, so, you need to divide 785ft by 4 1/2 to see how many seconds it takes. The answer for this is 174.4, we can make this 174 4/9.
**VERY IMPORTANT** If you use 174 4/9, this equals 215 seconds, it asks for below this, so you can use ANY number for this that it above this number.
Now for the inequality, look at the question, it asks how long will it take to get below, not equal to or more below, meaning that you can cancel out the inequality signs with lines below them. So your answer is 270 > ,
Please tell me if this is right, if its not let me know I apologize.

Basically what you do is multiply the distance by the time, for example:
7 1/2 miles = 1/2 hour
so to get the amount of miles in one hour you get the miles and times it by two so it would go like this:
7 1/2 | 15 |
= | = |
1/2 | 1 |
then for one and a half you get the 1 hour answer and add the first one like this:
22.5 miles = 1 1/2 miles
and you continue that pattern!!! If you need more help just reply to this answer i'm in 7th grade so i can help with this stuff

1. 2016 Summer Olympics
First place:
Second place:
Third place:
Fourth place:
Fifth place:
Sixth place:
Seventh place:
Eighth place:
2.
3.
4.
Additional Challenge (Tip: slower means adding time to the original time):
1. Research the winners of the first eight places in the 100-meter men’s race
during the last summer Olympics and their recorded times in the final event.
2. Calculate the average time of the eight top finalists.
3. If the runner who got first place, ran 1500 meters at the same pace as he did
the first 100 meters; what would his final time be?
4. If the runner who received 8th place kept running at the same pace as he did
in the first 100 meters, how many meters would he be able to run in the
amount of time it took the first-place winner in Step Three to run 1500 meters?
Additional Challenge: Last, research the first-place winner of the women’s
100-meter race in the last summer Olympics and record her winning time.
Pretend the winner of the women’s competition ran 1000 meters. Her pace for
the first 100 meters would be the same as her award-winning Olympic time;
however, every 100 meters after that would be .9 seconds slower than the
previous 100 meters, how long would it take her to run 1000 meters?
Display your data in a table or graph showing the pace she ran every 100 meters.
(For example, if the women’s first place winning time was 9.61, she would run her
first 100 meters at a pace of 9.61. She would run her next 100 meters at a pace of
10.51, .9 seconds slower than her previous 100 meters and so on.)
On your sticky note, provide the following:
• Record the times of the first eight runners in the last summer Olympics
for the men’s 100-meter dash. Record the average times of the winner.
• Record the first-place winner’s name, his winning time and what his final
time would be if he ran 1500 meters.
• Record how many meters the 8th place men’s winner would be able to
run in the same time that it took the first-place winner to run 1500
meters.
• Record the name of the winner of the women’s 100-meter race in the
last summer Olympics and her winning time. Create a table to show the
female’s pace during her 1000-meter run that includes her final time.
