Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:
a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:
Then, use the squares in the equation:
Then, subtract 100 from both sides to isolate b:
Finally, square root both sides to get your answer:
Then round to the nearest tenth which gives you 17.3.
#1) d) large
#2) b) 80
#3) b) 3300
There were more responses for large in the survey, so they should focus on large.
There were 120 medium and large shirts sold out of 150 total sold:
120/150 = 0.80 = 80%
There were 11 out of 150 shirts sold that were small:
11/150(45000) = 3300
Answer:
81
Step-by-step explanation:
Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]
= so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.
You could set up another proportion 1/11 = x/891
