When finding the area you multiply the base by the height.
None of the other answers equal 80 so your answer is A.
The area of the parallelogram is 80mm^2. So, we'll go through each option to figure out what figure has the same area.
A - 1/2(4 x 20) = 40
B - 1/2(15 + 25) x 2 = 40
C - 1/2(6 + 14) x 8 = 80
D - 20 x 8 = 160
ANSWER:
Option 3 (C) - A trapezoid with bases of 6mm and 14mm and a height of 8mm

the lateral area of a cone with a diameter of 15 yards is about 287.5 square yards. to the nearest tenth, what is the slant height of the cone in yards?
Answers
To calculate the slant height of a cone with a diameter of 15 yards and lateral area of 287.5 square yards, divide the lateral area by the product of pi and the radius of the base. The slant height is approximately 12.3 yards when rounded to the nearest tenth.
To find the slant height of a cone with a known lateral area, we use the formula for lateral surface area of a cone: L = \\(\pi\\)r\ell, where L stands for lateral area, r for radius of the base, and \ell for the slant height. Given the diameter of 15 yards, we first calculate the radius as half the diameter, which is 7.5 yards. The equation with the given lateral area (287.5 square yards) would look like this: 287.5 = \\(\pi\\) \\times 7.5 \\times \ell. Solving for \ell, we divide the lateral area by \\(\pi\\) times the radius:
\ell = 287.5 / (\\pi \\times 7.5)
To get an approximate value, we use \\(\pi\\) = 3.1416:
\ell \\approx 287.5 / (3.1416 \\times 7.5)
\ell \\approx 12.27 yards
Thus, the slant height of the cone is approximately 12.3 yards when rounded to the nearest tenth.

Pre-image point N (6,-3) was dilated to point N(2,-1) What was the scale factor used?
Answers
The scale factor is 1/3
Explanation:
Given that the original point is has coordinates (x,y) and that the dilated point has coordinates (x',y'), we can see that:
x' = k * x
y' = k * y
where k is the scale factor
Now, for the given point we have:
original point = (6 , -3)
dilated point = (2 , -1)
Now, applying the above formula, we will find that:
For x-coordinate:
2 = k * 6
k = 2/6
k = 1/3
Check using the y-coordinate:
-1 = k * -3
k = -1 / -3
k = 1/3
From the above, we can confirm that:
k = 1/3

Heather is planning a dessert display. She needs 4 ounces of strawberries for each dessert.
Part A: Heather is not sure how many desserts she will make. Write an expression with a variable that represents the amount of strawberries Heather needs for the desserts. Identify what the variable represents.
Part B: If Heather has 24 ounces of strawberries, how many desserts can she make? Create an equation and show all work to solve it.
Answers
Answer:6
Steps: Divide both numbers by the coefficient(number with variable(x). Which is 4. Divide both sides by 4.
Part A: The expression [tex]4\cdot d[/tex] represents the number of strawberries Heather needs for the desserts.
Here, the variable "d" represents the number of desserts Heather will make.
Part B: Heather has 24 ounces of strawberries, she can make 6 desserts.
Mathematically, an expression is a combination of numbers, variables, operations, and functions that are composed together according to specific rules to represent a computation or relationship of mathematics. It can be thought of as a mathematical phrase or formula.
Part A: Let's represent the number of desserts Heather will make with the variable "d".
The expression that represents the number of strawberries Heather needs for the desserts can be written as:
[tex]4 \times d[/tex].
Here, the variable "d" represents the number of desserts Heather will make.
Part B: If Heather has 24 ounces of strawberries, we can set up an equation to determine the number of desserts she can make.
[tex]4 \times d[/tex] = 24 ounces.
To solve for "d," we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 4 ounces/dessert:
d (desserts) = [tex]\frac{24}{4 }[/tex]
Simplifying the right side of the equation:
d (desserts) = 6 desserts.
Therefore, Heather can make 6 desserts with 24 ounces of strawberries.
Therefore, [tex]4 \times d[/tex] represents the number of strawberries, where variable "d" is the number of desserts and Heather can make 6 desserts with 24 ounces of strawberries.

Kelsey bought a circular rug that is 12 feet in diameter. The rug has a blue boarder and a red circular center that is 4 feet in diameter. What is the area of the blue boarder? Round to the nearest 10th place
Answers
Final answer:
To calculate the area of the blue border of the circular rug, subtract the area of the red center from the area of the entire rug. Using the area formula for a circle, the area of the blue border is approximately 100.5 square feet when rounded to the nearest tenth.
Explanation:
To find the area of the blue border of Kelsey's circular rug, we first need to calculate the area of the entire rug and then subtract the area of the red circular center. The diameter of the entire rug is 12 feet, which means its radius is 6 feet. Similarly, the diameter of the red center is 4 feet, giving it a radius of 2 feet. We use the formula for the area of a circle, A = πr^2, where A is the area and r is the radius.
First, we calculate the area of the entire rug with a radius of 6 feet:
Atotal = π * 6^2 = π * 36 = 36π square feet.
Next, we calculate the area of the red center with a radius of 2 feet:
Acenter = π * 2^2 = π * 4 = 4π square feet.
Now, we subtract the area of the red center from the total area to find the area of the blue border:
Aborder = Atotal - Acenter = 36π - 4π = 32π square feet.
To provide an answer rounded to the nearest tenth, we approximate π to 3.14:
Aborder ≈ 32 * 3.14 ≈ 100.48 square feet, which rounds to 100.5 square feet as the area of the blue border.
You own Everything's Coming Up Roses flower shop. Your employee makes 4 deliveries per hour. The distance between the shop and the first delivery is 12 1/3 miles. The distance between the next three deliveries is 8 3/4 miles; 17 2/8 miles; and 23 2/3 miles respectively. The distance from the final delivery to the shop is 10 5/10 miles. What is the average distance for all segments of this trip? 14.48 miles
Answers
Final answer:
The average distance for all segments of the flower shop deliveries trip is calculated to be 14.5 miles.
Explanation:
To calculate the average distance travelled for all segments of the trip, we first convert each distance to an improper fraction or decimal for ease of calculation and then find the sum of all the segments.
After this, we divide the total distance by the number of segments.
The distances given are:
12 1/3 miles which is 12.333... miles (or 37/3 as an improper fraction)8 3/4 miles which is 8.75 miles (or 35/4 as an improper fraction)17 2/8 miles which is 17.25 miles (or 69/4 as an improper fraction)23 2/3 miles which is 23.666... miles (or 71/3 as an improper fraction)10 5/10 miles which is 10.5 miles (or 21/2 as an improper fraction)The total distance travelled is the sum of all these distances:
12.333... + 8.75 + 17.25 + 23.666... + 10.5 = 72.5 miles
There are 5 segments in the trip, so to find the average, we divide 72.5 miles by 5:
72.5 miles / 5 = 14.5 miles
Therefore, the average distance for all segments of this trip is 14.5 miles.

a right rectangular prism with a square base is cut parallel to its base the shaoe exposed is a cross section which shape bast describes this cross section?
A-triangle
B-trapezoid
C-square
D-rectangle not a square
Answers
A cross section obtained by cutting a right rectangular prism with a square base parallel to its base will also be a C. square, as it reflects the shape of the prism's base.
The question is asking about the shape of a cross section obtained by cutting a right rectangular prism with a square base parallel to its base. Such a cut would expose a shape on the surface of the prism that directly corresponds to the shape of the base. Since the base is given as a square, the cross section in this case would also be a square. The hypothesis of the right angle implies that the sides of the prism are perpendicular to the base, thereby maintaining the square shape upon slicing parallel to the base.
The cross section would not be a triangle (option A) or a trapezoid (option B), as these shapes do not correspond to a square base. It would not be a rectangle that is not a square (option D), because the length and width of the cross section would be the same, maintaining its square shape. Therefore, the correct answer is option C - a square.

One cubic foot of sand weighs about 100 pounds. Approximate the weight of the cone-shaped pile of sand. Round your answer to the nearest hundred pounds.
Answers
To approximate the weight of a cone-shaped pile of sand, find the volume of the cone using the formula V = (1/3)πr²h. Multiply the volume by the weight of one cubic foot of sand (100 pounds) to find the weight of the pile. Round to the nearest hundred pounds.
Explanation:To approximate the weight of a cone-shaped pile of sand, we first need to find the volume of the cone.
The formula for the volume of a cone is V = (1/3)πr²h, where r is the radius of the base and h is the height.
Let's say the radius is 2 feet and the height is 5 feet.
Plugging these values into the formula, we get V = (1/3)π(2²)(5) = 20π.
Now, since one cubic foot of sand weighs about 100 pounds, we can multiply the volume of the cone by 100 to find the approximate weight.
Therefore, the weight of the cone-shaped pile of sand is approximately 20π × 100 = 2000π pounds.
Rounding to the nearest hundred pounds, the weight is approximately 6283 pounds.

Which equation is the perpendicular bisector of the line segment with endpoints (-2,4) (6,8)
Answers
y = -2x + 10
Explanation:
The general equation of the linear line is:
y = mx + c
where m is the slope and c is the y-intercept
1- getting the slope:
slope of the given two points is:
slope = [tex] \frac{8-4}{6--2} = 1/2[/tex]
We know that the line we are looking for is perpendicular to the line having these two points. Therefore, the product of the slope should be equal to -1.
This means that the slope of the line we are looking for is -2
The equation of the line we are looking for now is:
y = -2x + c
2- getting the y-intercept:
To get the y-intercept, we need a point that belongs to the line.
We know that the line passes through the midpoint of (-2,4) and (6,8). Therefore, we need to get the midpoint first:
midpoint = ([tex] \frac{x1+x2}{2} , \frac{y1+y2}{2} [/tex])
midpoint = (2,6)
Now, to get the value of the c, we will use the point we have, substitute in the equation and solve for c as follows:
y = -2x + c
6 = -2(2) + c
6 = -4 + c
c = 10
Based on the above, the equation of the line is:
y = -2x + 10

15. No, this would not be neccesary because if I were to distribute 1/2 to both 4 and 6, I know that I would get half of those numbers which would give me 2x+3. I also know that if I distribute 1/3 to both 9 and 24, I would get 1/3 of each number which would be 3 and 8.
how much would $200 invested at 4% interest compounded monthly be worth after 8 years round your answer to the nearest tenth
Answers
Answer:
The amount is $275.3
Step-by-step explanation:
We can use amount formula
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the amount
P is money invested
r is interest rate
n is number of periods
t is time in years
we are given
P=200
r=4%=0.04
t=8
n=12
so, we can plug these values
[tex]A=200(1+\frac{0.04}{12})^{12\times 8}[/tex]
we can simplify it
and we get
[tex]A=275.3[/tex]
So,
The amount is $275.3
