one bag contains x pencils
5 bags contain 5x pencils
after adding 3 pencils to each bag
total no of pencils = 5(x+3)
According to question,
5(x+3)=45
x+3=45/5
x+3=9
x=6
one bag contained 6 pencils before adding
Answer/Step-by-step explanation:
Apply trigonometric bratio formula where applicable, to find the value of x in each case. Recall the acronym, SOHCAHTOA. This will help toe ash determine which ratio formula to use depending on the information given.
4.
Opp = x
Hyp = 14
Therefore, apply SOH. Which is,
Multiply both sides by 14
(nearest tenth)
5.
Adj = x
Hyp = 14
Therefore, apply CAH. Which is,
Multiply both sides by 14
(nearest tenth)
6.
Opp = x
Adj = 5.4
Therefore, apply TOA. Which is,
Multiply both sides by 5.4
(nearest tenth)
7.
Opp = x
Adj = 33
Therefore, apply TOA. Which is,
Multiply both sides by 33
(nearest tenth)
If you want to find the probability, just make a fraction of the number of times that outcome happened over the total amount of tests:
Open: 3/50= 0.06 or 6%
Closed: 7/50=0.14 or 14%
Side: 40/50= 0.8 or 80%
Hope this helps!
