32 students would be on the trip. What I did to solve it was a proportion. 8students/ 3 chaperones= x students/12 chaperones.
8*12= 96 and 96/3=32. Therefore 32 students were on the trip.
Answer:
x ≈ 20.31
Step-by-step explanation:
By applying tangent rule in the given right triangle,
tan(55°) = 
Measure of the opposite side = 29 units
Measure of the adjacent side = x
Substitute these values in the expression,
tan(55) = 
x = 
x = 20.306
x ≈ 20.31
Set up a ratio comparing the sample portion to the whole portion.
x= # of all dogs likely to have chip
Sample: 8 out of 50
Whole: x out of 2,300
8/50= x/2300
cross multiply
(50*x)= (8*2300)
50x= 18400
divide both sides by 50
x= 368
ANSWER: 368 dogs in Clarkson are likely to have a microchip.
Hope this helps! :)
11. 8/7
14. 13/10
17. 11/14
Step-by-step explanation:
Putting values of x and y
2 = 4 + 2
2 = 6
= 6-2
= 4
