A piece of cardboard has two circles punched out of it.
What is the approximate area of the remaining cardboard? Use 3.14 for pi and round to the nearest whole number.
Answers
(area of rectangle) - 2(area of circle)
There is a 2 in front of the area of the circle, since there are two identical circles punched out of the rectangle.
First, find the area of the rectangle. The area of the rectangle is given by the following formula:
length * width
You already have your two values for length and width. Plug those values into the formula:
[tex]14 * 18 = 236[/tex]
236 is the area of the rectangle.
Now we'll find the area of the circle.
The diameter of the circle is 2. The radius is one half of the diameter, so the radius is 1.
The area of a circle is found with the following formula:
[tex]A = \pi r^{2}[/tex]
pi is equal to 3.14, so replace the pi symbol with the 3.14. Then, plug your radius into the equation.
[tex](3.14) * 1^{2} = 3.14[/tex]
The area of the circles is 3.14.
Plug your areas into the first equation above.
[tex]236 - 2(3.14) = 236 - 6.28 = 229.72[/tex]
The approximate area of the cardboard is 229.72.

If the mean of a symmetrical distribution is 42, which of these values could be the median of the distribution?
Answers
Answer: 42
Answer:
42
Step-by-step explanation:
The median of a distribution is the exact center of the distribution, you start taking out numbers equally from the outside to the center, and eventually you will find the median, in a symmetrical distribution that means that there are the same number of values to the sides of the median, and the mean of a symmetrical distribution is always going to be equal to the median, so in this case the median and the mean would be the same, 42.

The coordinate plane represents a map. Each grid unit represents 20 miles. A retail company has a warehouse at N(40, 60). A store is located at P(40, −30). How long will it take a truck driving at 50 miles per hour to drive from warehouse N to this store?
Answers
The truck will take 36 hours to travel from warehouse N to store P.
To calculate the time it will take for a truck to travel from warehouse N to store P, we need to first determine the distance between the two points in the coordinate plane. Since each grid unit represents 20 miles, we will use the coordinates of N(40, 60) and P(40, -30) to calculate the distance in grid units and then convert that into miles. The two points share the same x-coordinate, so the truck is only traveling in the north-south direction. By subtracting the y-coordinate of P from that of N, we find that the two points are 90 grid units apart in the y-direction (60 - (-30) = 90). After converting the grid units into miles by multiplying by 20, the total distance is 90
20 miles = 1800 miles.
The truck drives at a speed of 50 miles per hour, so we divide the total distance by the truck's speed to find the time it takes to travel from N to P:
1800 miles / 50 miles per hour = 36 hours.

Jade is making a square birthday card and she's going to put a ribbon borders on each of the 4 equal sides piece of ribbon that is 33 inches long do you have all of the ribbon how many inches of ribbon conget put on all
equals side
Answers
(she will have 1 inch left)
Final answer:
Jade can use 8.25 inches of ribbon on each side of her square birthday card by dividing the total ribbon length of 33 inches by the number of sides, which is 4.
Explanation:
Jade is making a square birthday card and wants to put ribbon borders on each of the 4 equal sides using a piece of ribbon that is 33 inches long. To determine how much ribbon can be put on each side, we divide the total length of the ribbon by the number of sides of the square. Since a square has four sides, we divide 33 inches by 4.
33 inches ÷ 4 sides = 8.25 inches per side
Therefore, Jade can put 8.25 inches of ribbon on each side of the birthday card.

Sharon is paving a rectangular concrete driveway on the side of her house. The area of the driveway is 5x^2 + 43x - 18, and the length of the driveway is x + 9.
Additionally, Sharon plans to install a carport over a small portion of the driveway. The volume that the carport can enclose is 48x^3 + 68x^2 - 8x - 3, and the area of driveway beneath the carport is 8x^2 + 10x - 3.
Determine the width of the entire driveway and height of the carport in terms of x. Replace the values of m and b to complete the expression that represents the width of the entire driveway on the first line, and then replace the values of m and b to complete the expression that represents the height of the carport on the second line.

im just trying to graduate....
Answers
The height of the carport is 6x+1.
We complete polynomial long division for both of these.
For the driveway:
Dividing 5x²+43x-18 by x+9, we first see how many times x will go into 5x². It goes in 5x times; we write this in the division problem above 43x. Multiplying back through,
5x(x+9) = 5x²+45x. This goes below 5x²+43x. We now subtract:
5x²+43x-(5x²+45x)= -2x; this goes below the 45x we wrote earlier. Bring down the -18.
Now we see how many times x goes into -2x; it goes -2 times. This goes beside our 5x in our answer at the top. Multiplying back through,
-2(x+9) = -2x-18. This goes below our -2x-18 we had, and gives us an answer of 5x-2 with a remainder of 0.
For the carport:
To divide 48x³+68x²-8x-3 by 8x²+10x-3, we see how many times 8x² will go into 48x³. It will go 6x times; write this above -8x. Multiplying back through,
6x(8x²+10x-3) = 48x³+60x²-18; write this below 48x³+68x²-8x. Now subtract:
48x³+68x²-8x-(48x³+60x²-18) = 8x²+10x; this goes below our 48x³+60x²-18. Bring down the -3.
Now we want to see how many times 8x² will go into 8x². It goes 1 time; write this beside our 6x at the top. Multiplying back through,
1(8x²+10x-3) = 8x²+10x-3; write this below the 8x²+10x-3 we have already down. When we subtract these, we get a remainder of 0, with our answer up top as 6x+1.

picking a month of the year in the day of the week (fundamental counting principle)
Answers
If you are picking a month, there are 12 options.
If you are selecting a day of the week, there are 7 options.
If you are doing both, you multiply the two numbers together.
12 x 7 = 84
Using the fundamental counting principle to pick a month of the year in the day of a week would give 84 combinations.
How to find the number of combinations ?
The Fundamental Counting Principle is a concept in combinatorics that helps you calculate the total number of possible outcomes when you have multiple independent choices or events.
Choices for the Month: There are 12 months in a year. So, you have 12 choices for the month.
Choices for the Day of the Week: There are 7 days in a week
To find the total number of possible combinations of a month and a day of the week, you simply multiply the number of choices for each event:
Total Number of Combinations = Number of Choices for Month x Number of Choices for Day of the Week
Total Number of Combinations = 12 months x 7 days
= 84 combinations
In conclusion, there are 84 different combinations of selecting a month of the year and a day of the week using the Fundamental Counting Principle.
At a fair, each person can spin two wheels of chance. The fist wheel has numbers 1,2, and 3. The second wheel has the letters A and B. (A) list all the possible outcomes of the computed event. (B) if you spin both wheels, what is the probability that you get either a 1 or an A? Explain.
Answers
(a) There are 3 numbers on the fist well and 2 letters on the second, so number of possible outcomes = 3*2 = 6 possible outcomes
The possible outcomes are 1A, 2A, 3A, 1B, 2B, 3B
So in total there are 6 possible outcomes as shown above if a person can spin the two wheels
(b) From possible outcomes A or 1 can appear four times namely: 1A,2A,3A and 1B
So probability is number of successes/ total number = 4/6

Layla drew a quadrilateral with 4 right angles and 2 pairs of opposite sides sides that are parallel.What quadrilateral best describes her drawing?
Answers
Based on the given information, Layla's drawing is a special type of quadrilateral known as a rectangle.
What is the rectangular shape?Rectangles are quadrilaterals having four equal vertices and parallel sides that are equal to one another.
A rectangle is defined as a quadrilateral with four right angles and opposite sides that are parallel and congruent (i.e., they have the same length).
In Layla's drawing, she stated that there are two pairs of opposite sides that are parallel, which satisfies this definition.
Furthermore, the fact that all four angles are right angles also fits the definition of a rectangle.
It is important to note that not all quadrilaterals with two pairs of parallel sides and four right angles are rectangles.
For example, a parallelogram with four right angles is a special type of rectangle known as a square, which has all sides congruent.
Therefore, based on the given information, Layla's drawing best describes a rectangle.

10 < –2b or 2b + 3 > 11
Answers
10 < –2b can be reduced by dividing both sides by -2; you must then reverse the direction of the < sign: -5 > b, which is the interval b < -5: (-infinity, -5).
2b + 3 > 11 reduces to 2b > 8, which in turn reduces to b > 4: (4, infinity).
It may be helpful to graph these sets.
If you really do mean "10 < –2b or 2b + 3 > 11," then the "solution" is made up of two sub-intervals: b < -5 and b > 4.
