Austin correctly answered 92% of the questions on a geography quiz. Liz answered 47 of the 50 questions correctly. Which student got the most questions correctly.
(if you answer this may you please show your work)
Answers
To find the percent Liz got correct, you would do 47/50 to get 0.94. You would then move the decimal 2 places to get 94%.
94%>92%
Answer:liz scored better
Step-by-step explanation:
Liz scored better because how to find a percentage is dividing whatever two numbers you have by each other so it would be 47 / 50 which equals 0.94 then you times it by 100. Which would equal 94% which is better than a 92 which means Liz got the higher score

You can't find the area of it all at once so you must cut it in have to have two shapes like in the picture above and then name them A and B
Now for the shapes we must use the formula Area= Lentgh times Breath
Shape A: A= L x B

Dylan and Tiffany each constructed a two-color spinner. Dylan spun his spinner 3 times and calculated that the
relative frequency of his spinner landing on blue (0.67) and on red (0.33). Tiffany spun her spinner 200 times
and calculated the relative probability of her spinner landing on blue (0.60) and on red (0.40).
How can Dylan's and Tiffany's calculations be used to evaluate the fairness of the two spinners?
Answers
Answer:
You can calculate the likeliness of the spinner landing on blue or red as the more spins you have the more accurate the results would be. In this case after 200 spins Tiffany calculated that the spinner landing on blue has a 60% chance while landing on red has a 40% chance. Therefore this might not be fair as there is a 60% chance landing on blue.

Hey there!

CONVERT the EQUATION
-589 + x + 90 - 1 = 0
COMBINE the LIKE TERMS
x - (-589 + 90 - 1) = 0
x - 589 + 90 - 1 = 0
x - 499 - 1 = 0
x - 500 = 0
ADD 500 to BOTH SIDES
x - 500 + 500 = 0 + 500

Answer:
50
Step-by-step explanation:
When n = 6, the length is 3 * 6 + 2 = 20 and the width is 6 - 1 = 5. We know that the perimeter of the rectangle is twice the sum of its length and width. The sum of the length and width is 20 + 5 = 25 and twice that is 25 * 2 = 50.
Answer:
50
Step-by-step explanation:
At the bottom we see n = 6, that's already solved for us so now we plug it into the equation.
3n+ 2 and n - 1, When a variable is next to a number, you multiply the number of the variable and the original number together, So in this case n = 6 and we have 3n + 2, 3n = 18 (3x6) and then 18 + 2 = 20. And since n = 6, N - 1 = 5 (6-1) So we add the first sum of 3n+2 = 20 + N - 1 = 5 which gives us 25. Now that we have our sum of width and length we multiply that by 2 in order find the perimeter. 25x2 = 50.

Plant B is 6 2/3 inches tall. Plant C is 4 4/15 inches tall. Complete the sentences and show your reasoning.
Plant C is ?? times as tall as Plant B.
Plant C is ?? inches ???? (taller or shorter) than Plant B.
Answers
Answer:
Step-by-step explanation:
Plant B is taller than Plant C.
We need to determine by how much.
To do this, we divide 6 2/3 inches by 4 4/15 inches.
The LCD is 15, and so we have: 5/4
Plant B is 1 and 1/4 times taller than Plant C.
This can be restated as Plant C is four-fifths as tall as Plant B.Plant C is shorter than Plant B, as we saw earlier.
The difference is found through subtraction: 100/15 - 64/15 = 36/15 inches = 12/5 inches shorter, or 2 2/5 inches shorter

10)We have to calculate the average speed if we know the distance and time that Johnatan can jog. The distance
distance=3 2/5 miles = 3.4 miles.
Time=7/8 hour = 0.875 h
Then we will use the formula for the average speed ( velocity )
velocity=distance/time. v = 3.4 m / 0.875 h = 3.866 mph
so therefore The average speed is 3.866 mph.
11) divide 120 / 7/4 (remember 120 = 120/1)
Which means you have to cross multiply (an important part on fraction division, that is, your division would be 120x4 / 1x7).
Then 120x4= 480
And 1x7 = 7
Then you get 480/7, which is the same as 68 4/7 mph

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500

Tyrell is traveling to Chicago, Illinois. He takes a cab service from the airport to his hotel. The table shows the linear relationship between the number of miles the cab travels, x, and the total fee, y.
Cab Fare
Number of Miles Total Fee
2 $13.00
5 $17.50
7 $21.50
10 $25.00
15 $32.50
What does the y-intercept mean in this situation?
For every additional mile the cab travels, the total fee increases by $10.00.
For every additional mile the cab travels, the total fee increases by $1.50.
When the cab travels 0 miles, the total fee will be $1.50.
When the cab travels 0 miles, the total fee will be $10.00.
Answers
The meaning of the y-intercept in this situation is that: D. when the cab travels 0 miles, the total fee will be $10.00.
How to calculate the slope of a line?
Mathematically, the slope of a straight line can be calculated by using this formula;
From the table, we have the following parameters:
Points (x, y) = (2, 5) and (13.00, 17.50)
Next, we would calculate the slope as follows:
Slope = (17.50 - 5)/(13.00 - 2)
Slope = 12.50/11.
Slope = 1.14.
Mathematically, the standard form of the equation of a straight line is given by;
y - y₁ = m(x - x₁)
Where:
x and y represents the points.
m represents the slope.
b represents the y-intercept.
Substituting the given parameters into the standard equation, we have;
y - 13.00 = 1.14(x - 2)
y - 13.00 = 1.14x - 2.28
y = 1.14x - 2.28 + 13.00
y = 1.14x + 10.72
Answer: D When the cab travels 0 miles, the total fee will be $10.00.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
