Step-by-step explanation:
This circle graph shows the percent of land occupied by each continent.
The area of North America is approximately 220 million km2
.
Use the percents in the circle graph.
Find the approximate area of each of the other continents,
to the nearest million square kilometres.
The approximate areas of the continents (excluding North America) are as follows:
- Australia: 11 million km^2
- Europe: 15 million km^2
- Antarctica: 18 million km^2
- South America: 26 million km^2
- Africa: 44 million km^2
- Asia: 66 million km^2
To find the approximate area of each continent, we will multiply the given percentages by the area of North America (220 million km^2).
1. Australia:
Percentage: 5%
Approximate area: 0.05 * 220 million km^2 = 11 million km^2
2. Europe:
Percentage: 7%
Approximate area: 0.07 * 220 million km^2 = 15.4 million km^2 (rounded to 15 million km^2)
3. Antarctica:
Percentage: 8%
Approximate area: 0.08 * 220 million km^2 = 17.6 million km^2 (rounded to 18 million km^2)
4. South America:
Percentage: 12%
Approximate area: 0.12 * 220 million km^2 = 26.4 million km^2 (rounded to 26 million km^2)
5. Africa:
Percentage: 20%
Approximate area: 0.20 * 220 million km^2 = 44 million km^2
6. Asia:
Percentage: 30%
Approximate area: 0.30 * 220 million km^2 = 66 million km^2
Note: These values are rounded to the nearest million square kilometers.

HELP WITH THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
B., E.
Step-by-step explanation:
what was the difficulty ? this is just to understand the movement of a thrown rock.
what happens, when you throw a rock through the air ? it will first move up a little bit, reaches a maximum height, and then drops down again.
that is what the graphic shows.
so, can A. be correct ? no. as we move from 0 seconds to the right (time passes) the height of the rock increases first (before decreasing again later on).
can C. be correct ? no, it would mean that the function would look the same on both sides of the x-axis. this is clearly impossible.
can D. be correct ? no, nowhere in the graph is the height (= the functional value, the y to the x) negative.
can F. be correct ? no, we clearly see the maximum height at 1.5 seconds. at 3 seconds the height is actually at its minimum.

Answer:
A) $24
Step-by-step explanation:
Looking at the graph, each gallon of gasoline is $3. Therefore, the equation would be y = 3x. To solve for 8 gallons, substitute the value into the equation.
y = 3(8) = 24
Therefore, the cost of 8 gallons of gasoline would be $24.

Using the tables as experimental data, determine whether it is more likely for a new food establishment to succeed and earn up to $25,000, or whether it is more likely for a new financial establishment to succeed and earn profits in either the $25,000-50,000 range or the $50,000-75,000 range, and how much more likely the one situation is than the other. Express all probabilities as percentages to two decimal places, and express differences by number of percentage points (for example, 23% is 5 percentage points greater than 18%). a. The situation involving the financial establishment has a probability 11.14 percentage points higher than the situation involving the food establishment. b. The situation involving the financial establishment has a probability 12.03 percentage points higher than the situation involving the food establishment. c. The situation involving the food establishment has a probability 2.08 percentage points higher than the situation involving the financial establishment. d. The situation involving the food establishment has a probability 2.36 percentage points higher than the situation involving the financial establishment.
The situation involving the food establishment has a probability of "2.08 % " points higher than the situation involving the financial establishment
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The question is incomplete, as the required table which is not given.
we have the following parameters:
The probability that the establishment earns up to $25k = 10.59%
The probability that the establishment earns between $25k - $50k or $50k - $75k = 8.56%
Using the above values, the difference in the probabilities are;
d = 10.59% - 8.56
d = 2.03%
Hence, the true statement about the probability is option (d)

What is the experimental probability of popping a polka dot balloon? Express your answer as a fraction,decimal, and percent
Answer:
Experimental probability [popping a polka dot balloon] = 1 / 8
Step-by-step explanation:
Missing information;
Number of striped balloons = 17
Number of solid balloons = 18
Number of polka dot balloons = 5
F ind:
Experimental probability [popping a polka dot balloon]
Computation:
Experimental probability [popping a polka dot balloon] = Number of polka dot balloons / Total number of balloons
Experimental probability [popping a polka dot balloon] = 5 / [17 + 18 + 5]
Experimental probability [popping a polka dot balloon] = 5 / 40
Experimental probability [popping a polka dot balloon] = 1 / 8

What is division in mathematics? What is a mathematical function, equation and expression?division : Division is the process of splitting a number or an amount into equal parts.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the following division as follows -
(36m ÷ 9m)
We have the following expression -
36m ÷ 9m
So, we can write -
(36m/9m)
36/9
4
Therefore, the expression (36m ÷ 9m) is equivalent to 4.

Plz help me ASAP!!!! No files plzzzzzz. PLZZ and THX!
Answer:
y = 1x - 5
Step-by-step explanation:
We will use the slope equation for this: y = mx + b
y is our output/answer
m is our slope, or the rate of change
x is our x coordinate. For example, in (3,2) x would be 3.
b is our y intercept, or where the line passes through the y axis.
Knowing this, we can fill out the blanks.
when we look at one point on the grid, and then find the next closest number from the point we chose, we can see that the slope is 1 so we now have: y = 1x + b
to find b, we find where the line passes over the y axis which on our grid is -5. Normally we would write: y = 1x + 5 Since we have a negative 5 or -5, we will change the + to a -
This means we write y = 1x -5.
I hope this helps you and have a great day :D
what is the difference between the domain and the range of a function?
Answer:
The domain is all the x values of a function while the range is all the y values of a function.
Answer:
Step-by-step explanation:
The domain of a function is the set of input (x-) values for which the function is defined. The range is the set of output (y-) values; often there are limitations.
For example, the sine function y = sin x is defined for all real x; for every input x, there is a corresponding output y. The sine function has a limited range in that the minimum value of the sine is -1 and the max is +1. There is no graph above y = -1 or below y = +1.

Where is it saves three times as much money as Anna. If a represents Anna savings. Which relationship shows how much money they have saved, S, together
Answer:
S = 4a
Step-by-step explanation:
Rosa saves three times as much money as Anna. If a represents Anna's savings, which relationship shows how much money they have saved,
together?
Let
S = Total money they have saved,
together
a = Anna's savings
Rosa saves three times as much money as Anna
Rosa = 3 * a
= 3a
Total savings = Anna's savings + Rosa's savings
S = a + 3a
S = 4a
