Answer:

I think it's a.)

Step-by-step explanation:

It says that they already started off with $400 and raise $80 a day, and <em>d</em> stands for the number of days.

densk [106]

Answer:

\[y < = 300\]

Step-by-step explanation:

Let x = number of out-of-state students at the college

Let y = number of in-state students at the college

As per the given problem, the constraints are as follows:

\[x < = 100\]    --------- (1)

\[y = 3 * x\]      --------- (2)

From the given equations (2), \[ x = y/3 \]

Substituting in (1):

\[y/3 < = 100\]

Or, \[y < = 300\] which is the constraint representing the incoming students.

What is 0.0592 in scientific notation
DiKsa [7]

Answer:

5.92 times 10 to the 2nd power.

If the simple interest on ​$6,000 for 2 years is ​$840​, then what is the interest​ rate?
ankoles [38]

Answer:

7 %

Step-by-step explanation:

  • i do not know if you use this but I use S.I=P×R/100×T
  • S.I=840
  • P for principal(the money you borrow or lend) =6000
  • T for time=2 years.
  • R for rate=???
  • In order to find out the rate, you need to substitute all these numbers into their respective places.
  • 840=6000×r/100×2
  • 6000/100=60
  • 840=60×r×2
  • 840=120r
  • r=7%
