Answer:
104 inches
Step-by-step explanation:
To solve this, we use a circle theorem. The circle theorem to use is that a line from the center of a circle is perpendicular to a chord and it divides the chord into exactly two equal parts.
So therefore, we shall be having a right angled triangle if we join the edge of the chord to the center of the circle.
So in this circle, we have the distance from the center of the circle to the chord, the radius of the circle and half the length of the chord.
The length of the radius serves as the hypotenuse.
Let’s call the radius r.
The other two sides measure; 40 and 96 respectively.
Mathematically, using Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides;
r^2 = 40^2 + 96^2
r^2 = 10,816
r = √(10,816)
r = 104 inches
I would say 1000 mL becuase the other choices are too small
Answer:
The distance of Jack's Father's work from home in miles is 45 miles.
Step-by-step explanation:
a) Data and Calculations:
Normal time taken by Jack's father to drive to work = 30 minutes
Time taken when traffic is bad = 1 hour longer
Speed when traffic is bad = 30 mph slower
Distance covered when traffic is bad, with time taken as 1 hour 30 minutes = time * speed = 1.5 * 30 = 45 miles
b) Jack's father normally drives at 90 mph (45 *2), this is why it normally takes him 30 minutes between his home and workplace when the traffic is not bad. However, when traffic is bad, it takes him one hour longer and he drives at 30 mph slower.
