Answer:
scale factor= 4.7
Step-by-step explanation:
47/10= 4.7
32.9/7= 4.7
28.2/6= 4.7
To figure out the scale factor for the smallest to the largest triangle, divide the larger number by the smaller number (of the same side).
If you wanted to get the scale factor of the largest to smallest triangle, you would just do the opposite.
ex. 10/47, 7/32.9...
Answer:
radius = 21
Step-by-step explanation:
Well, since the graph starts at (0,50), making our y-intercept 50, we can knock off D as an option.
The next step is to find the slope. To do this, find two points and subtract the y values over the x values. (Just make sure that whichever y value you start with - start with the same x value).
So we have >>> (50, 200) and (0,50) from earlier.
200 - 50 / 50 - 0 = 150/50 or 3/1, or 3.
This makes the correct answer A since the equation is represented as y = mx + b, where m is the slope and m has a value of 3.
One pizza serves four people so, you will need 10 pizzas for 40 people so that make the answer (A.)
