The area of figure ABCD is:
24 square units.
We see that the given points form the vertices of a trapezium ABCD with bases AD and CB with measure,
AD= 3 units
and CB=5 units
and the height of the trapezium is: AB= 6 units.
Hence, the area of trapezium ABCD is:
Hence, the area of figure ABCD is:
24 square units.
Answer: 15 girls
Step-by-step explanation:
27 - 3 = 24
24/2 = 12
12 boys
12 + 3 = 15
15 girls
15+ 12 = 27
Answer: 15
Step-by-step explanation: Personally, I would try finding the number of boys first and then subtract the number of total students by the number of boys. To find the boys, you need to subtract three from 27 since those 3 are girls which leaves you with 24. It says there is half the number of boys than girls when you subtract 3 so 24 divided by 2 is 12. The number of boys is 12 so now all you have left to do is subtract 27-12 to find the number of girls, which is 15. I hope this helped you and sorry if it’s really long :)
Answer:
The answer would be a=2.
Step-by-step explanation:
Since both sides of the equation are being multiplied by b then you would divide both of them by B. This will just remove the B from the equation entirely and leave you with a=2. I hope that this was helpful.
Answer:1.96875
Step-by-step explanation:
If
A=-12/8=-1.5
And
B=-21/16
And if we’re multiplying a and b
Then
A*B=C=1.96875
The area of one square is 49 square inches.
A square is a two-dimensional figure and a four-sided polygon which has it's all sides equal in length and the measure of the angles are 90 degrees. The total interior angle is 360 degrees.
For the given situation,
The figure is made up of two identical squares. So it forms a rectangle.
Let width be x then length be 2x.
Perimeter of rectangle = 42 inches
The formula of perimeter of rectangle is
⇒
⇒
⇒
⇒

Thus one side of the square is 7 inches.
So formula of area of square is
⇒
⇒
⇒
Hence we can conclude that the area of one square is 49 square inches.

first solve for the perimeter of the rectangle
2w + 2l = 42
since the length of the rectangle is twice as long as the length and width of the square
2w = l
solve using substitution
2w + 2(2w) = 42
2w + 4w = 42
6w = 42
w = 7
are is length x width. a square has the same length and width
7 x 7 = 49
the area of one square is 49
The percentmarkup from $33 to $45 is 36.4%.
Option D is the correct answer.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Initial amount = $33
Final amount = $45
The percentmarkup.
= (45 - 33)/33 x 100
= 12/33 x 100
= 36.4%
Thus,
36.4% is the percentmarkup.
