X = 25cm , i used pythagoras theorem to calculate this, 7^2 + 24^2 = 625, the square root of 625 = 25
So hmm notice the picture below
simply get the area of the segment, and subtract it from the area of the circle, what's left, is the difference
notice your circle, has a radius "r" of 18
Answer:=6x3−9c
Step-by-step explanation:
3x3+4x2+3x3−4x2−9c
=3x3+4x2+3x3+−4x2+−9c
Combine Like Terms:
=3x3+4x2+3x3+−4x2+−9c
=(3x3+3x3)+(4x2+−4x2)+(−9c)
=6x3+−9c
Answer:
x =21
Step-by-step explanation:
So we know that:
And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:
Now, solve for x. Add 30 to both sides. The left side cancels:
Now, subtract 2x from both sides. The right cancels:
Thus, the value of x is 21.
The ratio of the number of girls to the total number of children is 7 : 16.
<h3>
Ratio is defined as follows:</h3>
- It is a comparison between two or more numbers that measures sizes in relation to each other
- It describe how much of a thing is compared to another.
The number of girls in the playground = 7
The number of boys in the playground = 9
The total number in the playground is the sum of the number of girls and the number of boys.
Therefore,
total children in the playground = 7 + 9 = 16
The ratio of the number of girls to the total number of children can be express as follows:
