Answers
The area of a trapezium ABCD in which AB || CD, AB = 14 cm, CD = 8 cm. Given
that AB = 23 cm, CD = 7 cm and AD = 17 cm.
Answer:
The area of a trapezium ABCD given the measure of sides is determined by the following equation: A = 1/2 (AD + BC) * h, where h is the height of the trapezium. Using the given information, the area can be calculated as A = 1/2 * (14 + 8) * (23/2) = 200 cm^2.

Answer:
Radius=10
Diameter=20
circumference=62.8
Area=314
Answer:
Radius: 10 inches
Diameter: 20 inches
Circumference: 62.8 inches
Area: 314 inches squared
Step-by-step explanation:
Radius:
They have already given you the radius (10), so no formula is needed.
Diameter:
To find the diameter, multiply the radius by 2, so:
2 × 10 = 20
Circumference:
To find the circumference, use this formula:
C=2πr
2 × π (3.14) = 6.28
6.28 * 10 = 62.8
Area:
To find the area, use this formula:
A=πr²
π (3.14) × 100 = 314

You have 15 yards of ribbon for your gift boxes. Each box gets the same amount of ribbon. How much ribbon will each of your 20 gift boxes get?
Answers
Answer:
3/4 of a yard or 0.75 of a yard for each gift box.
Step-by-step explanation:
15 yards of ribbons
20 gift boxes
20/15 = 0.75
0.75 would be split evenly for all 20.
Answer:
2.25 feet
Explanation:
You would get 0.75 yards because 20 boxes divided by 15 yards is 0.75 yards
What is the difference between mean and median
Answers
The difference between the mean and median is that the mean is the average number. f.e: 1, 2, 2, 2, 3, 3, 4, 5 - and if you add all those up, the mean would be 3, or 2.
But the median is the number in the middle Number.
What if you have 2 medians, though?
Well, that’s easy to solve IMO.
F.e: 22, 22, 23, 23, 23, 24, 24, 24, 25, 25
The median is either 23 or 24, right?
Okay. That’s simple. But what exactly do we do?
Let me show you:
So get the sum of 23 and 24, which is 47.
Now divide 47 by 2. And what do we get?
23.5.
Now round that, and you get 24. So 24 is the median!
Hope that helps!
Answer:
mean is the AVERAGE of all numbers
Step-by-step explanation:
because when you add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!
and a median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.

What is the perimeter of the object (Hint: Not all numbers should be used to find your answer) (Provide number only in your answer) *
Answers
Answer:
27 IN
Step-by-step explanation:
If you want to calculate the perimeter of an irregular trapezoid, there's no special formula - just add all four sides:
Trapezoid perimeter = a + b + c + d
Maybe you've noticed, but it's the formula for any quadrilateral perimeter.
There's also an option that that presents itself with certain special trapezoids - like an isosceles trapezoid, where you need a, b, and c sides. Another example is a right trapezoid, where the length of the bases and one leg are enough to find the shape's perimeter (the last leg is calculated using Pythagoras' Theorem).

buck is building a horse corral with the shape and dimensions shown in the sketch. He wants to make sure the corners of the corral measure 90 degrees
how long must diagonal AC be so angle B is a right angle?
uprgigt corner is D other side is C
Downleft is A across from B
16 ft down and 12 ft side
Answers
Answer:
BxA=F
Step-by-step explanation:
Diagonal AC must be 20 feet so that ∠B will be 90°.
According to asked question, buck is creating a horse coral by designing in such a way that corners will be at 90°.
So according to question we have to make ∠B as 90°.
So quadrilateral ABCD becomes a rectangular.
Therefore ΔABC will be a right-angle triangle in which we can use Pythagoras theorem to measure the diagonal AC.
What is Pythagoras Theorem?The Pythagoras Theorem says that in a right-angle triangle, the square of the hypotenuse is the sum of square of the other two sides of the right-angle triangle.
In the right-angle tringle ΔABC,
AC²=AB²+BC²
⇒ AC²=16²+12²
⇒ AC²=256+144=400
⇒AC=√400
⇒AC=20 feet
Therefore, Diagonal AC must be 20 feet so that ∠B will be 90°.
