Let a be the number of trumpet players
Let b be the number of saxophone players
---------------------
(1) a = b-10
(2) b =3a
----------------
Substitute
(2) into (1)
(1) a =3a-10
(1) 2a =10
(1) a = 5and
(2) b = 3(5)(2)
b = 15
------------------
There are 5 trumpet players and 15 saxophone player
You need to know that:
1 ounce = 28.35 grams
So, 1 tube contains
3.0 oz × 28.35 = 85.05g total mass
Mass of Benzyl salicylate =
2.40/100 = Percentage of Benzyl salicylate (in numerical value)
= 0.024
0.024 × 84 = Mass of Benzyl Salicylate
=2.016g
If one tube contains
2.016g × 425 tubes
=856.8g
Then,
Converting into kg by (dividing by 1000)
=856.8 ÷ 1000
= 0.8568 grams
= 0.857g (3sf)
Answer:
0.5
Step-by-step explanation:
P(event) = number of times event occurs/ total number of trials
Hi, You are the person I answered last time!
P(event) = 8/16
8/16 simplified is equaled to 1/2.
1/2 is equaled to 0.5
Again, I'm pretty sure this is right because it says experimental probability... I hope this helps!
Answer:
Step-by-step explanation:
3 different china dinner sets, each consisting of 5 plates consist of 15 plates.
A customer can select 2 plates in
different ways.
2 plates can be selected from the same dinner set in
different ways.
Thus, the probability that the 2 plates selected will be from the same dinner set is
Well if there is no number I front of a variable it is a one. For example 12c-c: 12c-1c so just take the numbers and then subtract th m and bring the c down next to the answer. 12-1:11 so 12c-1c:11c
