Answer:
25%
Step-by-step explanation:
20 marbles total
5 black marbles
5/20 = x/100
x=25
30% , as:
Let the percentage of people preferring wooden skateboards be 'x'.
Therefore, x/100*643=209
x/100=209/643
x=209*100/643
x=20900/643
x=32.50.......
By rounding it off to 30, we get 30% as answer.
Answer is A... 0.25
2 1/2 = 2.5
2.5/10 = 0.25

Answer:
188.4
Step-by-step explanation:
because if you multiply 15.7 and 12 you get 188.4 and that is the area of the jumping space.
A quadrant is the area that is divided into the x and y axes
The quadrants in which tan and cot are positive are I and III
<h3>How to determine the quadrants</h3>
The tangent of an angle is calculated as:
While the cotangent of the angle is calculated as:
The above equations mean that:
For the tangent and cotangent of an angle to be positive, then the sine and the cosine of the angle must have the same sign.
- In the first quadrant, the sine and the cosine angles are positive.
- In the third quadrant, the sine and the cosine angles are negative.
Hence, the quadrants in which tan and cot are positive are I and III
