One painting shows 520 different types of ladybugs.
Another painting shows 750 different types. How many
times as great is the value of the digit 5 in 520 than the
value of the digit 5 in 750? How do you know?
Answer:
10 times greater
Step-by-step explanation:
the 5 in 520 is in the hundreds place value
The 5 in 50 is in the tens place value
50 *10 = 500
From units to tens-------------Multiply by 10 (2*10=20)
From tens to hundreds-------Multiply by 10 (20*10=200)
From hundreds to thousands----Multiply by 10 (200*10=2,000)
And so on
The value of 5 in 520 is in the hundreds place, so it equates to 500. Conversely, the 5 in 750 is in the tens place, meaning it equals 50. Thus, the 5 in 520 is 10 times greater than the 5 in 750.
Explanation:This question pertains to the place value in numbers, an essential mathematical concept. In the number 520, the digit 5 is in the hundreds place, which means its value is 5*100 = 500. On the contrary, in the number 750, the digit 5 is in the tens place, hence, it's value is 5*10=50.
Therefore, to find out how many times the value of the 5 in 520 is greater than the value of the 5 in 750, divide the value of the 5 in 520 (which is 500) by the value of the 5 in 750 (which is 50). So, 500 divided by 50 equals 10. This reveals that the value of the digit 5 in 520 is 10 times greater than the value of the digit 5 in 750.

What is the value of 22x + 3 when x = 5? How much money is 22 nickels and 3 pennies?
Answer:
113
$1.13
Step-by-step explanation:
22x + 3 when x = 5 is written 22(5) + 3
You multiply first, 22(5) = 110 + 3 = 113
a nickel is worth .05 so you mulitply .05 x 22 which gets you 1.1 and 3 pennies is .03 and when you add the two together you get $1.13
Answer: The value of 22x+3 is 113. The amount of money that equals 22 nickels and 3 pennies. That answer is also 1113.
Step-by-step explanation:
For the first problem u want to basically do 22 times 5 and that gives you 110. Then after doing that u want to do 110+3 which equals 113.
For the second one since nickels equal 5 cents u want to do 22•5 which gives you 110 and then you do 110+3 and that gives you 113.

Mike works two part time jobs while going to college. He works 8 and half hours a week at the ice-cream store for $10.55 per hour and 7 hours a week at the movie theater for 13.85 per hour. Work each of the following problems in decimal form.
1. How much does Mike earn a week before taxes are taken out of his paycheck?
2. If 22 percent of Mike’s paycheck is withheld for taxes, how much money is left for Mike?
3. At which Job does Mike earn the most before taxes, how much more?
4. If Mike spends $50 a week on entertainment, what percent of Mike’s paycheck is left after he pays taxes? In decimal form.
Answer:
1.$186.63
2.$145.57
3.$7.27 more
4.65.65%
Step-by-step explanation:
Mike has two part time jobs.
Job 1: Ice-cream store
Number of hours worked= 8.5 hours
Payment per hour=$10.55
Job 2: Movie theater
Number of hours worked=7 hours
Payment per hour=$13.85

Find the area of a square with side a when a=2 in, a=12 in, and a=0.8 in. Are the area of a square and the length of its side directly proportional quantities? Why or why not?
Answer:
4 inches²
144 inches²
0.64 inches²
Yes, the area of a square and the length of its side directly proportional quantities.
Step-by-step explanation:
In this question, we have to find the area of square by changing the lengths of a side. Given lengths are: 2, 12, 0.8. I will evaluate the area of each side and try to find out the relation between area and length of side.
First, we start with the smallest length (a=0.8 inches)
Area of a square is calculated by taking the square of single side (since both sides are equal).
Area of square = a²
Area of square = 0.8²
Area of square = 0.64 inches²
Area of square with smallest side length (a=0.8 inches) = 0.64 inches²
Secondly, we start with the 2nd highest length (a=2 inches)
Area of square = a²
Area of square = 2²
Area of square = 4 inches²
Area of square with second largest side length (a=2 inches) = 4 inches²
Thirdly, we start with the highest length (a=12 inches)
Area of square = a²
Area of square = 12²
Area of square = 144 inches²
Area of square with highest side length (a=12 inches) =144 inches²
As we can see, with the increase in the length of a side, area of square is also increasing. Therefore, yes the area of a square and the length of its side are directly proportional quantities as the area increases or decreases when the length of the side increases or decreases.
Answer:
They are directly proportional quantities.
Step-by-step explanation:
DEFINITION
Two quantities are said to be directly proportional if an increase in one quantity lead to an increase in the other quantity.
Area of a Square = [tex]Length^2[/tex]
Area of a Square of Length 2 inch = [tex]2^2=4 \:square \:inch[/tex]
Area of a Square of Length 12 inch = [tex]12^2=144 \:square \:inch[/tex]
Area of a Square of Length 0.8 inch = [tex]0.8^2=0.64 \:square \:inch[/tex]
Arranging the sides and corresponding area in ascending order:
(0.8, 2, 12) = (0.64, 4, 144)
We notice that as the length increases, the area also increases.
Therefore, the area of a square and the length of its side are directly proportional quantities.

You borrow bookcases to display 943 books. You plan to put 22 books on each shelf. There are 5 shelves. How many bookcases do you need
Answer:
9 bookcases.
Step-by-step explanation:
Total number of books = 943
Total number of books placed in one shelf = 22
Total number of shelves in one bookcase = 5
Total number of books displayed in one bookcase = [tex]No.\ of\ shelves\ in\ 1\ bookcase\times\ No.\ of\ books\ in\ each\ shelf[/tex]
Total number of books displayed in one bookcase= [tex]5\times 22=110[/tex]
Total number of bookcase required = [tex]\frac{total\ no.\ of\ books}{Number\ of\ books\ displayed\ in\ 1\ bookcase}[/tex]
Total number of bookcase required = [tex]\frac{943}{110} =8\frac{63}{110}[/tex]
So, 880 books can be displayed in 8 bookcases. and for the remaining 63 books we also require one more bookcase. Therefore, the total number of bookcases needed are 9.
A college football team wins eight games and loses three during its season. The margins of victory in the eight wins are (in points scored): 11 14 12 16 25 45 1 49 The relationship between the mean and median margin of victory is typical of distributions which, like this one, are
A) skewed to the right
B) nearly symmetric
C) skewed to the left
D) all positive
E) football shaped
Final answer:
The relationship between the mean and median margin of victory in a right-skewed distribution is explained.
Explanation:
The relationship between the mean and median margin of victory in this case defines a right-skewed distribution. In a skewed distribution, the mean tends to be farther out on the tail compared to the median. This is because in a right-skewed distribution, there are a few large values that pull the mean towards the right and away from the median, which represents the middle value. In this case, the mean margin of victory is 88.2, and the median margin of victory is 87.5. Therefore, the correct answer is option A) skewed to the right.

To transform the graph of y = x2 to y = (x - 12)2 + 3, subtract 12 from the x-coordinate to shift the graph horizontally and add 3 to the y-coordinate to shift it vertically.
Explanation:To transform the graph of y = x^2 to the graph of y = (x - 12)^2 + 3, we need to understand the effect of each transformation on the original graph. Here are the steps:
To translate the graph horizontally 12 units to the right, we subtract 12 from the x-coordinate of each point on the graph. The equation becomes y = (x - 12)^2.To shift the graph vertically 3 units up, we add 3 to the y-coordinate of each point on the translated graph. The equation becomes y = (x - 12)^2 + 3.By applying these transformations, we obtain the graph of y = (x - 12)^2 + 3, which is the original parabola shifted 12 units to the right and 3 units up.

b. There are horizontal and vertical asymptotes.
C. The graph intersects the x-axis in two places.
d. The range is 0 < y<.
Answer:
b. There are horizontal and vertical asymptotes
Step-by-step explanation:
The graph is a hyperbola with asymptotes of x=0 and y=0
The correct options regarding the graph of y = 1/x are:
b. There are horizontal and vertical asymptotes.
c. The graph intersects the x-axis in two places.
a. The domain of y = 1/x is all real numbers except x = 0 since division by zero is undefined.
b. The graph of y = 1/x has a vertical asymptote at x = 0, which means the function approaches infinity as x approaches 0 from the left side and approaches negative infinity as x approaches 0 from the right side.
There is no horizontal asymptote because the function does not approach a specific y-value as x approaches positive or negative infinity.
c. The graph intersects the x-axis in two places: once for positive x-values and once for negative x-values.
The x-intercepts occur when y = 0, which happens when x = 1 and x = -1.
d. The range of y = 1/x is y ≠ 0 since division by zero is undefined. The function can take on positive and negative values as x approaches positive or negative infinity, respectively.
Therefore, the range is y < 0 or y > 0, depending on the chosen interval.
