Answer:
16%
Step-by-step explanation:
Given the total number of students in a school = 675
Number of students at a squirrel during flu season = 108
Squirrels are known for transmitting flu disease, therefore if 108 students are at the squirrels during a particular day, there is possibility that this ones have contacted flu.
Percentage of those that have flu = number of students at the squirrels/Total number of students × 100%
= 108/675 × 100
= 10800/675
= 16%
This means that 16% of the students have flu
This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.
Answer:
Four boys and one girl.
Step-by-step explanation:
Total students wearing glasses = 5
Separate the students by x and x + 3. It is x + 3 for the boys because there are three more boys wearing glasses.
Girls = x
Boys = x + 3
Total = 5
<u>Calculate:</u>
x + x + 3 =5
2x + 3 =5
2x = 2
x = 1
Boys wearing glasses = (1) + 3 = 4
Girls wearing glasses = 1
Answer:
-1/8
Step-by-step explanation:
Perpendicular slopes are negative reciprocals
The slope of y=8x+5 is 8, because it is in slope intercept form: y=mx+b form, where m is the slope.
Negative:
8/1--> -8/1
Reciprocal:
Flip the numerator and denominator
-8/1--> -1/8
So, the perpendicular slope of 8 is -1/8
