Currently 100 students can eat for 20 days, so we need to find the number of days 125 students can eat.

Originally:
100 students eat for 20 days

New:
125 students eat for x days. Multiply original number of students by original number of days which will give the total amount of students per day. Then divide the total amount of students per day by the new number of students to find the new number of days.

x= (100 students * 20 days)/ (100+25)
x= (100 * 20)/ 125
x= 2000/125
x= 16 days

ANSWER: 125 students can eat for 16 days.

Hope this helps! :)

If DA = 6 and MD = 4, what is the length of DK?
Leto [7]

Answer:

DK = 9

Step-by-step explanation:

In triangle AMD,

h² = p² + b²

or, h² = 6² + 4²

or, h²= 36 + 16

so, h² = 52

so, AM² = 52

Take x as reference angle,

cos²x = 16/52

Now,

In triangle, AMK,

Taking x as reference angle,

cos²x = b²/h²

cos²x = AM²/MK²

or, cos²x = 52/MK²

Now,

cos²x = 16/52 = 52/MK²

or,

16/52 = 52/MK²

or, 16MK² = 2704

or, MK² = 2704/16

or, MK² = 169

so, MK = 13

Now,

DK = MK - MD

or, DK = 13 - 4

so, DK = 9

Quincy found 120 shells during four days at the beach. if quincy found the same number of shells each day, how many shells did h
Svetach [21]
If Quincy finds 120 shells in 4 days, we can use the equation 4x = 120 to find how many shells she found each day. 4x = 120 If we divide both sides by four we get x = 30 So Quincy found 30 shells each day.

What is the answer to 6+9y-18=-3
lara [203]
6 + 9y - 18 = -3   Combine like terms (6 and -18)
      9y - 12 = -3   Add 12 to both sides
             9y = 9    Divide both sides by 9
               y = 1
