Answer:Percent of the teachers surveyed had neither high blood pressure nor heart trouble = 24.99%
Step-by-step explanation:
We are given the following in the question:
Number of teachers surveyed = 120
Number of teachers had high blood pressure = 70
Percentage of teachers had high blood pressure =
Number of teachers had heart trouble = 40
Percentage of teachers had heart trouble =
Number of teachers had both high blood pressure and heart trouble = 20
Percentage of teachers had both high blood pressure and heart trouble =
Percent of the teachers surveyed had high blood pressure or heart trouble = Percent of teachers had high blood pressure +Percent of teachers had heart trouble - Percent of teachers had both high blood pressure and heart trouble
Percent of the teachers surveyed had neither high blood pressure nor heart trouble
= 100% - Percent of the teachers surveyed had high blood pressure or heart trouble

Answer:
Step-by-step explanation:
Well first we need to add the tip in order to find the total amount of cash needed to be paid.
0.3696 x 20 = 7.392
So lets just say $7.39
Add that to the sub total which is 36.96
36.96 + 7.39 = $44.35
Now, in order to figure out how much each friend should pay, we divide the total by 4.
44.35/4 = 11.0875
So lets just say $11.09
So each friend should pay about $11.09
Answer:
<h2>x = 64</h2>
Step-by-step explanation:
To find x we use tan
tan∅ = opposite / adjacent
From the question
The adjacent is x
The opposite is 30
So we have
tan 25° = 30/x
x tan 25 = 30
Divide both sides by tan 25
x = 30/tan 25
x = 64.34
x = 64 to the nearest tenth
