Answer:
Given:
Two trail maps:
Trail on the first map = 8 cm
Trail on the second map = 6 cm
Scale on first map = 1 cm : 2 km
A) What is the scale factor from the map to the actual trail?
For the first map, the scale factor is 1 cm: 2km. Therefore the actual trail is 8 centimeters * 2 kilometers = 16 km.
The scale factor of the second map is 16 km / 6 cm = 2.67 km : 1 cm
B) The length of the actual trail is 16 kilometers.
Step-by-step explanation:
In this exercise we have to use the knowledge of distance to calculate the value of the length, like this:
A) 1 cm
B) 16K
some of the information given in the statement was from:
Trail on the first map = 8 cmTrail on the second map = 6 cmScale on first map = 1 cm : 2 kmA) So to calculate the scale, you will need:
[tex]1 cm: 2km\\8 centimeters * 2 kilometers = 16 km\\16 km / 6 cm = 2.67 km : 1 cm[/tex]
B) So from the previous calculations we find the value of the length which is 16 kilometers.

Angus has 5 pounds of apples. Justin has 3 pounds of apples. Who has more? How do you know?
Answer:
Angus has more apples.
Step-by-step explanation:
The apples are measured in pounds for both Angus and Justin. Angus has 5 pounds of apples, and Justin has 3 pounds of apples. 5 is greater than 3, so Angus has more apples.
Americans eat an average of 100 acres of pizza per year. That is equivalent to 4,356,000 square feet of pizza per year. How is the area expressed using scientific notation?
Answer:
D. [tex] 4.356 * 10^6 [/tex] ft²
Step-by-step explanation:
Scientific notation of a number is expressed in the following form, [tex] a * 10^b [/tex]
Where,
a = decimal number (1 ≤ |a| < 10)
b = the power of 10 whereby the scientific notation is equivalent to the original number.
To express 4,356,000 square feet in scientific notation, do the following:
1. Move the decimal point to the left up to the last non-zero digit = a = 4.356
2. Since we moved the decimal point by 6 decimal places, therefore, b = 6
3. Substitute the values of the variables into
Thus:
4,356,000 = 3. Substitute the values of the variables into
a * 10^b
Thus:
4,356,000 = 4.356 * 10^6

Laguna del carbon, a salt lake located in. Argentina, lies 344 feet below sea level. El alto, Bolivia, is located approximately 13,000 feet above sea level. What is the difference in elevation Laguna del Carbon and El Alto?
Answer:
The difference in elevation between Laguna del Carbon and El Alto is 12,656 feet.
Step-by-step explanation:
Given that Laguna del carbon, a salt lake located in Argentina, lies 344 feet below sea level, while El Alto, Bolivia, is located approximately 13,000 feet above sea level, to determine what is the difference in elevation between Laguna del Carbon and El Alto, the following calculation must be performed:
13,000 - 344 = X
12.656 = X
Thus, the difference in elevation between Laguna del Carbon and El Alto is 12,656 feet.

What is the pie chart?A circular data visual with slices illustrating numerical proportions is called a pie chart. Each slice's angle in a pie chart corresponds to the material it represents.
In an election there were four candidates, J, K, L, and M. Teri is drawing a pie chart to show the results. The sectors for J and K have been drawn. Twice as many people voted for L as voted for M.
Let 'x' be the number of people who voted for L and M. Then the number of people who voted for J and K will be 2x.
The angle that needs to be used to draw the sector for L will be given as,
⇒ 360° × [x / (2x + 2x + x + x)]
⇒ 360° × [x / 6x]
⇒ 360° × 1/6
⇒ 60°
Altogether, 15,840 people voted. Then the number of people who voted for J will be given as,
⇒ [(2x) / (2x + 2x + x + x)] × 15,840
⇒ (1/3) × 15,840
⇒ 5,280

(1) You are given 2 choices:
(a) getting $500,000 tax-free for sure, and (b)taking a chance on a gamble that has a probability p of getting $1 million tax-free and probability 1-p of getting nothing. Clearly, if probability p is 100% in the gamble, as a rational and sane person, you will choose the gamble because you will have a 100% chance of getting $1 million; on the other hand, if p is 0%, you will choose $500,000 for sure. Now, by gradually reducing the probability p of getting $1 million in the gamble from 100% towards 0, find the probability p* for you will feel choice
(b) has about the same degree of attractiveness or desirability as (a) to you. Use p* to compute your utility of $500,000.
(2) Repeat (1) by changing choice (a) to getting $200,000 tax-free for sure. Note: the probability p* for the case will generally be smaller than the one for (1).
Answer:
The answer is "0.02%"
Step-by-step explanation:
It will propose the percentage model i.e ([tex]\frac{500000}{100}=5000[/tex]) to find a good bid Therefore one percentage means [tex]\$5000[/tex] or one individual gets [tex]\$5000[/tex] taxable income if the probability is [tex]1\%[/tex] . For even a chance of [tex]2\% \ of \ \$10000[/tex]
However if we increase the chances of 0-100% the amount also increases accordingly from 0-1 million, we get much more than $500,000 also as the degree of attraction. In[tex]\$200,000[/tex] respectively [tex]0-100\%[/tex] implies that its total will rise appropriately from [tex]0-\$200,000[/tex]. Thus, p* is at [tex]50\% =\$ 100,000[/tex] .

-x/6 + 6 = 32
Please help me! Thank you
(The -x/6 is a fraction in case you thought it was division)
Answer:
x = -156
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer: x=−156
Step-by-step explanation: −x/6 +6=32
−1 /6 x+6−6=32−6
−1 /6 x=26
( 6 /−1 )( −1 /6 x)=( 6 /−1 )(26)

Twenty rubber spheres were compressed with varying amounts of force. The widths and heights of the resulting shapes were measured. Here is a scatter plot that shows the measurements for each sphere.
The vertical axis of the scatter plot would be labeled vertical
in
.
Answer:
It would be on the side 0-12 so the Y axis
Step-by-step explanation:
Put Vertical Axis (In)
The vertical axis of the scatter plot is the height; on the other hand, if the sphere is 6 inches, the height is closer to 5 inches than to 11 inches.
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
we know that the vertical axis is :
In this scatter plot, the horizontal axis is the width; however, we know the second variable is the height and this should be in the vertical axis.
we know that the height if the width is six inches:
Following the trend of the graph, it can be concluded the height if the width is six inches is approximately 5 rather than 11 inches.
