Answer: About 3.06
Step-by-step explanation:
We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.
Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.
cos(θ) =
cos(40) =
0.766 ≈
3.06 ≈ x
x ≈ 3.06
Answer:
The number of cake for order is 15 cakes .
Step-by-step explanation:
Given as :
Total number of people to attend the dance = x = 60
The number of slices each person will eat = A = 2 slices
The number of slices per cake = y = 8 slices
Let The number of cake for order = z
<u>Now, According to question</u>
Total slices of cake required for 60 people when each people eat 2 slices = total number of people × number of slices each person will eat
i.e Total slices of cake required for 60 people when each people eat 2 slices = x × A
Or, Total slices of cake required for 60 people when each people eat 2 slices = 60 × 2 slices
Or,Total slices of cake required for 60 people when each people eat 2 slices = 120 slices
<u>Again</u>
∵ number of slices per cake = 8
∴ The number of cake for order =
Or, z =
i.e z =
∴ z = 15 cakes
So,The number of cake for order = z = 15 cakes
Hence,The number of cake for order is 15 cakes . Answer
