Suppose you want to buy a bike. The prices are $119, $139, $149, $179, $189, $199, and $209. You want the bike that costs $189. Should you use mean, median, or mode to convince your parents? Explain.

Answers

For mean:
119 + 139 + 149 + 179 + 189 + 199 + 209 = 1183
1183/7 (for the amount you added) = 169

For median: 

119, 139, 149, 179, 189, 199, 209.
Find the middle number: 179 (is your median)

For mode: 

119, 139, 149, 179, 189, 199, 209
Find the number that shows up the most: N/A (they all only show up once)


I believe Median will be your best choice (it has the closest answer to 189)

hope this helps
Hi!

The median would be your best bet at convincing your parents to get you a new bike for $189 because the median which is $179 is the closest value to the one you want.

Regular triangular pyramid has the slant height k=12 cm and lateral area AL = 198 cm2. Find the length of the base edge.

Answers

To find this answer you will use the formula for finding the area of the triangle because that shape is a triangle.  

A = 1/2 bh
198 = 1/2 x b x 12
198 = 6b
b = 33 cm

We know the total area and we know the slant height is 12 cm so we substitute these in and solve for h.

The length of the base edge is 33 cm.  You should substitute this back in to check.

1/2 x 33 x 12 = 198 square cm.

Answer:

The Answer is: 11 cm

A bicyclist heads east at 10km/h. After she has traveled 24.2 kilometers, another cyclist sets out in the same direction going 30km/h. About how long will it take the second cyclist to catch up to the first cyclist?

Answers

We know that the first cyclist has traveled 24.2 km at a speed of 10 km/h. Lets use the equation [tex]time= \frac{distance}{speed} [/tex] to find the time of the first cyclist:
[tex]t= \frac{24.2}{10} [/tex]
[tex]t=2.42[/tex]
So, we know that she has traveled for 2.42 hours.
 
We also know that after she has traveled for 2.42 hours another cyclist sets out in the same direction, so if [tex]t[/tex] represents the time of our first cyclist, the time of our second cyclist will be [tex]t-2.42[/tex].

Now we are going to use the equation [tex]distance=(speed)(time)[/tex] to relate the speeds and times of the two cyclist:
For the first one:
[tex]distance=10t[/tex] equation (1)
For the second one:
[tex]distance=30(t-2.42)[/tex] equation (2)

Replace (1) in (2)
[tex]10t=30(t-2.42)[/tex]
The only thing left now is solve for [tex]t[/tex]:
[tex]10t=30t-72.6[/tex]
[tex]-20t=-72.6[/tex]
[tex]t= \frac{-72.6}{-20} [/tex]
[tex]t=3.63[/tex]

We can conclude that the second cyclist will catch up the first cyclist after 3.63 hours.


Explain how you can compare the size of a product to the size of a factor when multiplying fractions without actually doing multiplication including model

Answers

Answer: If you multiply a number by a fraction less than 1, the resulting product will be smaller than the original fraction.

Imagine, if you had half a pizza and you ate one-half of that. You would multiply 1/2 by 1/2 and get an even smaller number. The result would be 1/4.

On the other hand, if you multiply a number by a mixed number that is larger than one, the result would be larger than when you started.

The Comparison size of product and factors is shown below.

What are factors?

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.

For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly.

A fraction less than one will result in a smaller product than the initial fraction when multiplied by a number.

Imagine that you only ate half of the pizza you ordered.

You would get a smaller value if you multiplied 1/2 by 1/2. It would come out to 1/4.

On the other hand, the outcome would be more than the starting value if you multiplied a number by a mixed number that is greater than one.

Plz help me....
thank you

Answers

To find the answer for that question you have to find the area of rectangle first, so you say 60*80 which equals to 4800 cm squared and then find the area of the box and not its volume so you say: 2(16*10)=2*160=320 cm squared
                                                              4(16*27)=4*432=1728 cm squared 
add 320+1728= 2048 cm squared 
Finally, to find the area of the left poster board you have to subtract the area of the rectangle which is 4800 cm squared by the area of the box which is 2048 cm squared so 4800-2048=2752 cm squared

1. The length of a bookshelf is 5 ft. The length of a model of this bookshelf is 3 ft. Find the scale factor of the model to the bookshelf. Enter your answer in the box.

2. A rectangular garden has a length of 8 ft and a width of 4 ft. A smaller garden was made, using a scale factor of 34 . Find the dimensions of the smaller garden. Enter your answers in the boxes.

Answers

1. You can find the scale factor bookshelf by dividing the actual length with model length.
If you put it into an equation, it would look like this

actual length= model length * scale factor
5ft= 3ft * scale factor
scale factor = 5ft/3ft= 1.667 times

2. You can solve this problem with equation used above. Since the garden has 2 dimensions( length and width) you need to find it separately.

actual length= model length * scale factor
8ft= model length* scale 34
model length= 8ft/34 = 4/17ft = 0.23529 ft

actual width= model width* scale factor
4ft= model width* scale 34
model width= 4ft/34= 2/17ft =0.11764 ft

Answer:

3 / 5 = 0.6 so the scale factor is 0.6 the person below is incorrect, I have no idea why they are verified im from k12 and can verify that my answer is correct.

Can ratios have decimals in them or do all the numbers have to be integers? E.g. is 7.8:1.3:6.5 a valid ratio?

Answers

What you have is a valid ratio in theory, but it might be easier to understand if it were simplified to integers:

78:13:65

It also depends on what your teacher is asking of you.

Final answer:

Yes, ratios can include decimals. They can represent quantities in numerous contexts such as scale distances, dimensions, and proportions. The ratio 7.8:1.3:6.5 is, therefore, a valid expression.

Explanation:

Ratios can indeed include decimals in them; they do not need to be limited to integers. Ratios are a way to compare two or more quantities, which can be whole numbers, fractions, or decimals. Just as fractions, ratios express the relationship between parts of a whole or between two quantities in a specific order. For example, the ratio 7.8:1.3:6.5 is valid and represents the relative quantities of three different entities. In many contexts, such as in scale distances or dimensions, the use of decimal ratios is quite common. When dealing with scale factor to find actual dimensions, the ratio could also include decimals, as it compares the scale dimensions to actual dimensions of an object or distance. For example, on a map with a unit scale of 1 inch equals 100 feet, the ratio would be written as 1/100 or in decimal form, 0.01/1.

When Mr. Krumm purchased a tie he paid $9.27, which included the 3% sales tax. How many dollars did the tie cost before the tax was included?

Answers

If $9.27 includes the 3% tax, then 
103% = 9.27

To find the price before tax, we need to find 100% of the price.

103% = 9.27
1% = 0.09
100% = 0.09 x 100 = $9

The price before tax is $9.

the circumfrence of a circle is 11 pie inches. what is he the area, in square inches, of the circle? Express your answer in terms of PIE

Answers

Please:  use "pi," this mathematical quantity is not written as "PIE."

Since C=2pi*r, and C=11 inches, r=(11 inches)/(2pi), or
                                                    r^2 = (121 sq in)/(2pi)

Then the area of this circle is A = pi*r^2, or pi*(121 sq in)/(4pi^2).  Reduce this and you will then have the area correct.  Its units of measurement are (inches)^2.

A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone? A) 2 cm B) 3 cm C) 4 cm D) 5 cm

Answers

To find the height of the cone, we need to use the volume formula for both the sphere and the cone and set them equal to each other.

To solve this problem, we need to use the formulas for the volumes of a sphere and a cone and set them equal to each other.

The volume ( V ) of a sphere with radius ( r ) is given by:

[tex]\[ V_{\text{sphere}} = \frac{4}{3} \pi r^3 \][/tex]

The volume ( V ) of a cone with radius ( r ) and height ( h ) is given by:

[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi r^2 h \][/tex]

Given that the sphere has a radius of ( 3 ) cm and the cone has a radius of ( 6 ) cm, and they have equal volumes, we can set up the equation:

[tex]\[ \frac{4}{3} \pi (3^3) = \frac{1}{3} \pi (6^2) h \][/tex]

Solving for ( h ):

[tex]\[ 36 \pi = 36 \pi h \]\[ h = 1 \][/tex]

Therefore, the height of the cone is ( 1 ) cm.

Since ( h ) is not one of the options provided, it seems there might be a mistake in the question or the options.

So, the height of the cone is 3 cm. Therefore, the answer is option B) 3 cm.
