Answer:
There are a total of 78
Step-by-step explanation:
Here we are to calculate the number of 7th grade students at Willow middle school given the information in the question.
Now, to calculate the number of people that attended the party, we add those that have left to those still remaining = 36 + 34 = 70 students
Now this number equals 90% of students
Thus let’s say the total number of students is x
90/100 * x = 70
90x = 100 * 70
90x = 7000
x = 7000/90
x = 77.77 which is approximately 78 students
nswer:
209.8
Step-by-step explanation:
the bottom is = 11 * 5
two of the sides are 11 * 9.3 / 2 because they are triangles, and then times 2 because there are two of them
the other two sides are 10.5 * 5 / 2 , and the * 2 because there are two of them again.
(11 * 5) + (11 * 9.3 * 2 / 2) + (10.5 * 5 * 2 / 2) =209.8
