Answer: The value of the sine of ∠C is 0.28.
Step-by-step explanation:
Let's draw a triangle again (see the picture below).
Remember SOHCAHTOA? It's:
-sin = opposite/hypotenuse
-cos = adjacent/hypotenuse
-tan = opposite/adjacent.
We need to use sin in here.
The sin of C is , which in a calculator, gives
Answer:
5 guests: 6 slices 10 guests: 3 slices 15 guests : 2 slices
Step-by-step explanation:
So, we have 30 slices of pizza and 5, 10, and 15 slices
So , we need to divide 30 by each of the guests
30÷5=6
30÷10=3
30÷15=2
We can also heck by multiplying teh guests by our answer
5*6=30 ✔️
10*3=30✔️
15*2=30✔️
So, for 5 guests, each oione gets 6 slices
For 10 guests, each guest gets 3 slices
For 15 guests, each guest gets 2 slices
The number of $1, $5 and $10 are 49, 44 and 22 respectively.
<h3>How to use equation to find the number of bills?</h3>
There are 3 denominations of bills in a wallet: $1, $5, and $10.
There are 5 fewer $5-bills than $1-bills.
let
x = number of $1 bills
Hence,
number of $5 bills = x - 5
There are half as many $10-bills as $5-bills.
number of $10 bills = 1 / 2 (x - 5)
Therefore,
x + x - 5 + 1 / 2 (x - 5) = 115
2x - 5 + 1 / 2 x - 5 / 2 = 115
2x + 1 / 2 x - 5 - 5 / 2 = 115
5 / 2 x - 7.5 = 115
2.5x = 115 + 7.5
x = 122.5 / 2.5
x = 49
Number of $1 bills = 49
Number of $5 bills = 49 - 5 = 44
Number of $10 bills = 1 / 2 (49 - 5) = 22
