Answer:
1. cm
2. 318.198 ft^2.
Step-by-step explanation:
Hmm. Very stuck. We'll just take it slow. :)
For the first one, we'll just square the bottom of the parallelogram, because
it's a square. The answer is above.
The second is a bit more complicated. The formula for the area of a parallelogram is (base) x (height)= A(area), but that will be of no use until we know the height (the dashed line on the left).
So, do let's go about finding the height with a 45-45-90 triangle.
The way these work is that the two short sides are equal to x, and the longer one is . So, in essence, .
15/=10.61
Both of the other two sides (one being the height) are 10.61 ft long.
Multiply that by 30:
30 x 10.61= and you get 318.198 ft^2.
Answer:
8:19
Step-by-step explanation:
Ball B: diameter in mm = 9.5 * 10 = 95 mm
Ratio of Ball A to Ball B = 40 : 95
= 8:19 answer
Answer:
It's 12/5 . When u divide the BC by AB ie. tanC becomes 12/5 .......Try it hope it helps!
She has 1 quarter, 1 dime and 13 nickels. So the probability that one coin at random is a nickel is 13/15.
My work:
1$= 100
1 quarter=25
1 dime=10
1+1+13= 15
25×1= 25
10×1= 10
5×13= 65
65+25+10= 100
-- Both pairs of sides of a rectangle are parallel.
Only one pair of sides of a trapezoid are.
-- A rectangle is a parallelogram.
A trapezoid isn't.
-- The opposite sides of a rectangle are equal.
The opposite sides of a trapezoid aren't.
-- All of the angles of a rectangle are right angles.
The angles of a trapezoid aren't.
-- The area of a rectangle is the product of (length) times (width).
The area of a trapezoid is (height) times (the average of the two bases).
