57.50/3=19,166
That means that one ticket costs 19,166.
15*19,166=287,49
So 15 tickets cost $287,49.
Answer:
c. 4.0
Step-by-step explanation:
It's a rectangle triangle and we have the measure of the hypotenuse (13.7) and an angle (16 degrees 55 minutes or 16.92 degrees) and we need to find the length of the opposite side of the angle.
Those elements are related through the sin of the angle.
So, if we want to get the opposite side...
If we round up to the first decimal, we do get 4.0.
So, let's put the test scores in fractions. We need them to have a common denominator, so let's use 10.
5/10=b 2/10=a 3/10= c or below
I added up 5/10 and 2/10 and subtracted that from 10/10 because it represents the rest of the test scores. We need to find how many students are 3/10.
We could multiply 3/10 by 30. Or we could divide 30 by 10, and multiply that by 3. Either way, we get 9.
So, 9 students scored a c or below on the test.
<span>Number of bowls left after 1 hour =
x - x/3 - 1/3 = 2x/3 - 1/3
</span><span> Number of bowls left after 2 hours = (2x/3 - 1/3) -
(2x/3 - 1/3)/2 - 1/2
= 2x/6 - 1/6 - 1/2
= 2x/6 - 4/6
= x/3 - 2/3
keep doing this untill u reach 0 bowls left
and then u'll get ur answer
