Answers
2. First you need to know about the pythagorean theorem which is
a^2 + b^2 = c^2. Look at the first picture below for more reference.
Next you use the pythagorean theorem to find out the right triangle sides to then know the length and width of the rectangle.
a = 8
b = unknown
c = 10
Now use algebraic steps. 8^2 + b^2 = 10^2 --) 64 + b^2 = 100 --) b^2 = 36 --)
b = 6 .
Finally you know the length which is 8 + 8 = 16 and the width which is 6, so the area of the rectangle is 16 x 6 = 96. And to look apporpriate 96in.^2 .

A 3-pound bag of sugar costs $9.12. What is the price per ounce
Answers
To find the price per ounce of a 3-pound bag of sugar costing $9.12, multiply the pounds by 16 to get the total ounces (48), then divide the cost by the total ounces to get $0.19 per ounce.
To calculate the price per ounce of sugar for a 3-pound bag costing $9.12, first determine the total number of ounces, since there are 16 ounces in a pound. Multiplying 3 pounds by 16 ounces per pound gives us 48 ounces. Next, to find the price per ounce, you divide the total cost by the total number of ounces ($9.12 ÷ 48 ounces).
Performing the division gives us the cost per ounce of sugar: $9.12 divided by 48 ounces equals $0.19 per ounce.
the area of a sector of a circle witha radius measuring 30cm 100 pi cm. what is the measure of the central angle that forms the sector?
Answers
Answer:
The central angle is [tex]40\°[/tex] or [tex]\frac{2}{9}\pi\ radians[/tex]
Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=30\ cm[/tex]
substitute
[tex]A=\pi (30)^{2}[/tex]
[tex]A=900\pi\ cm^{2}[/tex]
step 2
Find the central angle in degrees for a sector with area [tex]100\pi\ cm^{2}[/tex]
Let
x----> the measure of the central angle in degrees
Remember that the area of the circle subtends a central angle of 360 degrees
so
using proportion
[tex]\frac{900\pi}{360}=\frac{100\pi}{x}\\ \\x=360*100\pi/900\pi \\ \\x=40\°[/tex]
step 3
Find the central angle in radians for a sector with area [tex]100\pi\ cm^{2}[/tex]
Let
x----> the measure of the central angle in radians
Remember that the area of the circle subtends a central angle of [tex]2\pi[/tex] radians
so
using proportion
[tex]\frac{900\pi}{2\pi}=\frac{100\pi}{x}\\ \\x=2\pi*100\pi/900\pi \\ \\x=\frac{2}{9}\pi\ radians[/tex]
what is the lateral area of a regular pyramid with a square base which has a slant height of nine units and base side length of seven units?
Answers
Answer:
126 sq units.
Step-by-step explanation:
We want the side surface area only, we'll calculate both
For the sides, we have 4 triangles with a base of 7 and a height of 9 units.
The area of a triangle is calculated with A = (b * h)/2
So, each of the sides of the pyramid has an area of:
A = (7 * 9) / 2 = 31.5 sq units
There are four sides, so total lateral area: 4 * 31.5 = 126 sq units.
The total lateral area of that pyramid is 126 sq units.

between 32 and 36
between 32 and 37
between 27 and 32 and between 37 and 40
Answers
Answer:
"between 32 and 37"
Step-by-step explanation:
You can clearly look at the number line and see that each small line represents 1 unit.
Look at the box.
The left side of the box coincides with 2 units after 30, so 30 + 2 = 32
THe right side of the box coincides with 2 units after 35, so 35 + 2 = 37
Hence, the box part of the box plot contains all the values between 32 and 37
What are the coordinates of A’ after reflecting across the line x = 3? (2, 3) (3, 2) (3, 4) (3, –2)
Answers
Answer:
A(3,4), B(2,2), C(6,3), D(1,6)
Step-by-step explanation:
The coordinates you wrote out are different then what is shown on the graph, On the graph the points are A(3,2), B(2,4), C(6,3), D(1,0)
So when it comes to solving this first you need to know what you are going to reflect over, in this case its X=3 which would be a horizontal at point 3 and across.
Then you count how far away the points are from X=3 line and reflect.
Hard to explain but i hope it helps
The coordinates of A after reflecting across the line x=3 is (2,3).
We can find the coordinates of a given graph using the following :The first number or the number which is located to the left side of a comma in the point is the x coordinate of the ordered pair.It represents the amount of movement along the x-axis from the origin.The movement to the right side of the number is positive and to the left side of the origin of the number is negative.The reflection of the point(x,y) across the line y=x is (y,x).The reflection of the point (x,y) across the line y=-x is (-y, -x).Hence, the correct answer is (2,3) if it is reflected across the line x=3.

HELP!!!! FAST!!! Which graph represents a reflection of f(x) = 2(0.4)x across the y-axis?
Answers
Answer: The correct option is A.
Explanation:
The given function is,
To find the graph of this function after the reflecting across y-axis, first we have to find the graph of the equation.
The value of the function is 2 when x=0, so, the graph of given equation intersect the y-axis at 2.
In the equation . Since , so the given function is decreasing function
The value of f(x) is always positive, so the graph of f(x) is always above the x-axis. Thus, the graph must be above the x-axis after reflection across y-axis.
So, the option (2) and (4) and incorrect.
When we reflect the graph across the y-axis then,
It means when x approaches to large negative number the f(x) approaches to 0 and when x approaches to large positive number the f(x) approaches to infinite.
Therefore, the correct option is show in first graph.

There are 9 rows of 28 chairs set up for a play. A ticket to play costs $4. How much money will be made on ticket sales if all the seats are sold for the play?
Answers
First we have to determine how many chairs there are total. To do this multiply 9 by 28
9*28 = 252
That means you have a total of 252 chairs. Since we can assume that every person who buys a $4 ticket will only sit in one chair, we can say that if all the seats are filled then 252 people bought a ticket
To find the total price multiply the total chairs by the cost per ticket (or chair, which ever way you want to think of it as)
252 * 4 = 1008
You would make $1008

Step-by-step explanation:
Another way of stating this problem is find the Interquartile Range which is
Quartile 3 - Quartile 1.
The middle 50% of times that sophomores spend on homework per night refers to the interquartile range in statistics. This is found by ordering the data from least to greatest, splitting the data into 4 equal parts, then finding the values at the 1st and 3rd quartiles. The IQR is the range between these two values.
Explanation:The range of times that the middle 50% of sophomores spend on homework per night refers to the interquartile range (IQR) in statistics. This is because the middle 50% is equivalent to the data between the 1st quartile (25th percentile) and the 3rd quartile (75th percentile). To determine this IQR, you must first have the data you need- in this case, how long each sophomore spends on their homework. Then, you must order this data from least to greatest. Once ordered, you find the 1st and 3rd quartile values by splitting the data into 4 equal parts. Your IQR is then the range between these two values.
