First make a triangle by connecting the center point of the circle to one of the end points of the chord.
This will make a right triangle. The new formed line is the radius of the circle and will be the hypotenuse of the right triangle too.
Since one of the legs of the right triangle is half the chord, divide the chord in to two.
9.6 / 2 = 4.8
Now we can calculate for the hypotenuse.
Pythagorean theorem states that a²+b² = c²
So
√2.4² + 4.8² = c
√5.76 + 23.04 = c
√28.8 = c
5.4 = c
C is the hypotenuse and the hypotenuse is known as the radius of the circle.
So the radius is 5.4
For the first one the price per ounce is:
$4.56/15oz=0.304 dollars per ounce, which rounds to 0.3
For the second:
$5.98/25oz=0.2392 dollars per ounce, which rounds to 0.24
The second is the cheapest price per ounce and rounds to $0.24/oz so 0.24 is the answer
Answer:
A, C, and D are right.
A cube is basically six squares pushing against each other and since you can have a square you can also have a triangle considering you can cut it diagonally in half. And since a square is classified as a rectangle as well then C is also correct.

The first thing we should do in this casp is subtract both speeds.
We have then:
64.4 km / h - 64 km / h = 0.4 km / h
We must know the following change of units:
1h = 3600 s
1pie = 0.3048m
1km = 1000m
Applying the change of units we have:
0.4 * (1/3600) * (1000) * (1 / 0.3048) = 0.364537766 feet / s
Round to the hundredths
0.36 feet / s
Answer:
a zebra is 0.36 in feet per second faster.
