Multiply the first fraction by two and the second by twenty five on both top and bottom.
16/50 + 25/50 = 41/50
Answer:
A rectangle has 2 lines of symmetry
Answer:
x = 0.00559234073 for 1 second
x = 0.0111846815 for 2 seconds
Step-by-step explanation:
We first need to know that 1 mile = 1609.344 meters to get one unit to use or else it'll be confusing.
For 1 second, x will be replaced by 1.
So:
y=9(1)
y=9
And for 2 seconds, x will be replaced by 2.
So:
y=9(2)
y=18
These are the measurements in meters. Then, we need to find what it is in miles.
So we can use a proportion for this.
1/1609.344 = x/9
1609.344x = 9
x = 0.00559234073 for 1 second
For 2 seconds:
1/1609.344 = x/18
1609.344x = 18
x = 0.0111846815 for 2 seconds
The area of the entire circle = pi r^2
The area of the shaded area = (40/360) * pi r^2
r = 9 cm
Area of the shaded area = 1/9 * 3.14 * 9^2
Area of the shaded area = 3.14 * 9
Area of the shaded area = 28.26
Notice one of the 9s disappeared. Where did it go?
You could begin the problem by writing out 9^2
Area = 1/9 * 3.14 * 9 * 9 Notice that 1/9 will cancel out 1 of the nines.
28.26 yds = Shaded area.
