Suppose that there are 25 students in a class, each either a freshman, a sophomore, or a junior. How many students must be in th
Yakvenalex [24]

Answer:

at least 9 students in each cohort.

Step-by-step explanation:

Given that :

In a class, there are 25 students and each of them is either a sophomore, a freshman or a junior. We have to determine the number students in the same cohort.

Let us suppose there are equal number of students in each of the cohort.

Now let us assume that the number of the students in each cohort be 8, i.e. each as a freshman, a junior or a sophomore. Therefore, the total number in the all the cohorts will be 24 students only.

Thus, we can say that there are at least 9 freshman, at least 9 sophomore or at least 9 junior in each of the cohort.

Answer:

23.5 in

Step-by-step explanation:

To find the length of HJ in triangle GHJ, create <u>three equations</u> using the given information, then solve simultaneously.

<u>Equation 1</u>

HJ is two inches longer than GH:

⇒ HJ = GH + 2

<u>Equation 2</u>

GJ is 17 inches shorter than the sum of HJ and GH:

⇒ GJ + 17 = HJ + GH

<u>Equation 3</u>

The perimeter of ΔGHJ is 73 inches:

⇒ HJ + GH + GJ = 73

<u>Substitute</u> Equation 1 into <u>Equation 2</u> and isolate GJ:

⇒ GJ + 17 = GH + 2 + GH

⇒ GJ + 17 = 2GH + 2

⇒ GJ = 2GH - 15

<u>Substitute</u> Equation 1 into <u>Equation 3</u> and isolate GJ:

⇒ GH + 2 + GH + GJ = 73

⇒ 2GH + GJ = 71

⇒ GJ = 71 - 2GH

<u>Equate</u> the two equations where GJ is the subject and <u>solve for GH</u>:

⇒ 2GH - 15 = 71 - 2GH

⇒ 4GH = 86

⇒ GH = 21.5

<u>Substitute</u> the found value of GH into <u>Equation 1</u> and solve for HJ:

⇒ HJ = 21.5 + 2

⇒ HJ = 23.5

You invest $40,000 in two funds paying 4% and 52% simple interest. The total annual interest is $2080. How much do you invest in
natali 33 [55]

9514 1404 393

Answer:

  • 4% fund: $39,000
  • 52% fund: $1000

Step-by-step explanation:

Let x represent the amount invested at 52%. Then (40000-x) is the amount invested at 4%. The total annual interest is ...

  0.52x +0.04(40000-x) = 2080

  0.48x = 480 . . . . . . . . . subtract 1600, simplify

  x = 1000 . . . . . . . . . divide by 0.48

Then the amounts invested in each fund are ...

  4% fund: $39,000

  52% fund: $1000
