iren2701 [21]
You have 1200 pencils and you order more when your down to 500

So take 1200 - 500 to find how many pencils will be sold before you reorder.
1200 - 500 = 700

Then you take 700 / 24 to find how many days until you reorder.
700 / 24 = 29.1666666666666... You have round up because on day 29 you will have 504 pencils left

So 30 days until the manager reorders

In ΔIJK, the measure of ∠K=90°, KJ = 65, IK = 72, and JI = 97. What is the value of the cosine of ∠J to the nearest hundredth?
kow [346]

Answer:

\cos(J) = 0.67

Step-by-step explanation:

Given

\angle K = 90^o

KJ = 65

IK = 72

JI = 97

Required

\cos(J)

The question is illustrated with the attached image.

From the image, we have:

\cos(J) = \frac{KJ}{JI}

This gives:

\cos(J) = \frac{65}{97}

\cos(J) = 0.67010309278

\cos(J) = 0.67 --- approximated
