Answer:
a = 31.7
c = 39.1
Step-by-step explanation:
tan54 = a / 23
a = 23 * tg54
a = 31.7
sin54 = 31.7 / c
c = 31.7 / sin54
c = 39.1

Answer:
4 cm
Step-by-step explanation:
The perimeter of the original rectangle is ...
P = 2(L+W) = 2(4x + x) = 10x
The perimeter of the larger rectangle after we add "a" to each side is ...
P = 2(L +W)
= 2((4x+a) +(x+a))
= 10x +4a = 10x +16
4a = 16 . . . . . subtract 10x from both sides
a = 4 . . . . . . . divide by 4
The length added to each side is 4 cm.

Answer:
In order to determine the change in percent, I divided 4.02/1.37 to get approximately 2.9. I expressed this as a percent to get 290%.
Step-by-step explanation:
First, you have to find the unit rate by dividing
2000/6=333.33 but round it up to 333
So the unit rate is 333 bacteria per hour
Then, you have to multiply
333x16= 5,328 bacteria after 16 hours
The answer is that in 16 hours, there will be 5,328 bacteria
I hope this helps
