Answer:

2/3y

Step-by-step explanation:

If the class usually has y students and has 2/3 today, it can be represented by 2/3y.

Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.

So, in terms of y, 2/3y represents the number of students in class today.

The speed of light is estimated at 186,000 miles per second rounded to the nearest thousand miles per second.
4vir4ik [10]

It was rounding to the nearest THOUSAND.

We are looking at the thousands place, keep that in mind.

Remember: everything 5 and above is rounded up, everything below 5 is rounded down.

186,789 is above 500, it is rounded to 187,000

186,899 is above 500, it is rounded to 187,000

185,990 is above 500, it is rounded to 186,000

and 185,190 is below 500, it is rounded to 185,000

Only one matches the criteria of the question:

185,990 is above 500, it is rounded to 186,000

therefore the answer is 185,990 miles per second

Colin received a bonus check for 2,500$. He is going to deposit the money into his bank account that receives 5.5% simple intere
alex41 [277]
This is the concept of financial mathematics, the simple interest rate is given by:
S.I.=(PRT)/100
where:
P=principle=$2500
R=rate=5.5%
T=time=1 year
Hence;
S.I.=(5.5*2500.1)/100
=$137.5
Thus the total amount he had after 1 year will be:
2500+137.5
=$2,637.5
