Answer:
use the formula pi r 2 and simply multiply 3.14 times 16.
All you have to do is find the slope of the graph.
1) Pick 2 points: (8,9) and (16,18) for example
2) Use the slope formula (y2-y1)/(x2-x1)
3) Once you know the slope, you know how much the graph will rise for each x-unit. Find the x distance between 24 and the new point (36), and use can calculate how high the y value should be
Does that help?
Answer:
12
Step-by-step explanation:
If there are 3 classrooms that each have 25 desks and there are a total of 87 students, how many more desks need to be added to a 4th classroom, that was originally empty, so that each of the students has a desk to sit in?
25 * 3 = 75
87 - 75 = 12
Answer:
3(x+7)/4
Step-by-step explanation:
Three times the sum of a number and 7 will be 3(x+7) because it is triple the amount of that unknown number plus seven and then after that we divide what we get from 3(x+4) and divide that by 4 which makes the equation 3(x+7)/4.
