He can make 18 pieces. Observe:
22.5/1.25=18
Just use a calculator.
Round the numbers to the nearest ten thousand:
63,000 km & 20,000 km
Then find the difference (subtract):
63,000 km - 20,000 km = 43,000 km
Don't forget to put the unit of measurement on there (km)
Hope this helps :)
Answer:
(x - 3)² + (y + 4)² = 90 or [3√10)²
Step-by-step explanation:
We need to calculate the radius of this circle. To do this we calculate the distance from the center (3, -4) to the point (6, 5).
As we move from (3, -4) to (6, 5), x (the run) increases by 3 and y (the run) increases by 9. Thus, the distance between these points, according to the Pythagorean Theorem, is
r = √[3² + 9²], or r = √90, or r = 3√10.
Using the standard equation of the circle, (x - h)² + (y - k)² = r², we obtain
(x - 3)² + (y + 4)² = 90 or [3√10)²

Since you have the slope, you can start your equation with y= -8/7x +b. To find b, plug the X value for the point you were given in for the X (-8/7•4) you get -32/7 or -4.57. Then you take the given Y value(4) and subtract the number you just found (4-(-4.57)). You get 8.57. That means your equation is Y= -8/7 + 8.57
