Answer:the third one shows parallel lines cut by a transversal
Step-by-step explanation:
Riaz : Ali
3 : 2
Add the two values; so 3 + 2 is 5
Then 100/5 = 20
So: 20 x 3 = 60
and 20 x 2 = 40
Riaz = 60%
Ali = 40%
Then write 60% and 40% as a fraction:
60% = 3/5 (3 over 5)
40% = 2/5 (2 over 5)

(btw sorry in advance if you spot a mistake in my answer)
Answer:b
x=3-y/7
Multiple 7
7x=3-y
Subtract 3
7x-3=-y
Times both sides by negative 1
-7x+3

Exact Area = 1200 - 300pi square cm</h3><h3>
Approximate Area = 257.522203923062 square cm</h3>
Work Shown:
The area of the rectangle is 40*30 = 1200 square cm
Note how we have 4 circles along the horizontal dimension which is 40 cm, so each diameter is 40/4 = 10 cm, and the radius is 10/2 = 5 cm
Each circle has an area of pi*r^2 = pi*5^2 = 25pi
There are 4*3 = 12 circles, so the circle areas combine to 12*25pi = 300pi
Using a calculator, we find that 1200 - 300pi = 257.522203923062 approximately. Round this however you need to.
Answer:
121 degrees
Step-by-step explanation:
The "arc length" formula is s = rФ, where Ф represents the central angle in radians (not degrees).
Here r = 18 ft and s = 38 ft, and so:
38 ft
s = rФ becomes Ф = ------------ = 2.111 radians
18 ft
which, in degrees, is:
2.111 rad 180 deg
------------- * --------------- = 121 degrees, to the nearest degree
