The area of a triangle is found by multiplying the base by the height, then dividing that by 2:
Area = 10 * 7 = 70
70 / 2 = 35 square yards.

the product will increase by 2n
Answer:
2,200 students
Step-by-step explanation:
To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.

Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.
900(110) = 45(x)
99,000=45x
2,200 = x
So, there is a 7 hour span. There is 35 degree change total. So solve. Take 37/7=5
5 is the average
