19/20= 0.95
Divide 19 and 20 to get your answer:)
Answer:
Step-by-step explanation:
The question is not clear. So, assuming that the expression you need to simplify is this one:
You need to remember a property called "Power of a power property". This property states the following:
Therefore, you need to apply the Power of a power property explained before, in order to simplify the expression provided in the exercise, multiplying the exponents inside the parentheses by the exponent outside of the parentheses. Then:
Now, you must remember that:
Finally, you get:
Area of the two side triangles: 10 and 10 = 20
A = 1/2 bh
A = (10*2)/2 = 10
Area of rectangle:
A = l x w
A = 10 * 9
A = 90
90 + 20 = 110

We need to cut a 15m rope into 20 equal pieces. Written mathematically, it is as follows:
15/20 = length of rope segment in meters (a)
15/20 = a
Simplify
3/4 = a
In meters, each rope segment is 3/4m long. But, we don't want meters. We want centimeters.
100 cm = 1 m
3/4(100) = length of rope segment in centimeters (x)
3/4(100) = x
300/4 = x
75 = x
Each segment of rope is 75 cm long.
