Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:
[tex]A=\dfrac{a+b}{2}h[/tex]
Where, [tex]a,b[/tex] are parallel sides and [tex]h[/tex] is the vertical distance between the parallel sides.
Putting [tex]a=28.7, b=22.3,h=16[/tex] in the above formula, we get
[tex]A=\dfrac{28.7+22.3}{2}\times(16)[/tex]
[tex]A=\dfrac{51}{2}\times 16[/tex]
[tex]A=51\times 8[/tex]
[tex]A=408[/tex]
Therefore, the area of the trapezium is 408 square cm.

Answer: first two
1. 290
2. 90
IM PRETTY SURE THESE ARE RIGHT!! :D
Step-by-step explanation:
25 + 25 = 50
---
5 x 12 = 60
60 x 4 = 240
---
240 + 50 = 290
----------------------
2 x 9 = 18
18 x 4 = 72
---
2 x 2 = 4
4 x 2 = 8

A rectangular window is 4x inches wide and 8x inches long. What is an expression for the distance from one corner of the window to the opposite
corner? Give your answer as a simplified radical.
Answer:
Step-by-step explanation:
Pythagorean theorem
a² + b² = c² a = 4x b=8x
c = √(a² + b²)
c =√((4x)² + (8x)²)
= √(16x² + 64x²)
= √80x²
= √(16×5)x²
= 4x√5

There were 203 tickets sold for a wrestling
match. For activity card holders the price was
$1.25 and for non-card holders the price was
$2.00. The total amount of money collected was
$310. How many of each type of tickets were
sold?
Answer:
the number of activity card holders is 128 and non-card holders is 75 respectively
Step-by-step explanation:
Let us assume the activity card holders be x
And, the non-card holders be y
Now as per the given situation
x + y = 203
x = 203 - y
1.25x + 2y = 310
Now put the value of x in the above equation
1.25(203 - y) + 2y = 310
253.75 - 1.25y + 2y = 310
0.75y = 56.25
y = 75
And,
x = 203 - 75
= 128
Hence, the number of activity card holders is 128 and non-card holders is 75 respectively
how do you convert percentages into decimals??
Answer:
Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.

There are 4 consecutive even integers that sum to 332. What is the greatest of these
integers
Answer:
86
Step-by-step explanation:
let the numbers be x,x+2,x+4,x+6
Then x+x+2+x+4+x+6=332
4x=332-12=320
x=320/4=80
so numbers are 80,82,84,86
\angle DAC=\angle BAD∠DAC=∠BADangle, D, A, C, equals, angle, B, A, D. What is the length of \overline{AC} AC start overline, A, C, end overline? Round to one decimal place. Stuck
Answer:
AC = 4.5 units
Step-by-step explanation:
Given question is incomplete without the figure; find the figure attached.
By applying angle bisector theorem in the given triangle ABC,
(Since, AD is the angle bisector of ∠BAC)
[tex]\frac{AC}{CD}=\frac{AB}{BD}[/tex]
[tex]\frac{AC}{2.5}= \frac{6.8}{3.8}[/tex]
AC = [tex]\frac{6.8\times 2.5}{3.8}[/tex]
AC = 4.47
AC ≈ 4.5 units
Length of side AC in the given triangle = 4.5 units.
