Answer:
Each person will pay $9.78
Step-by-step explanation:
Given that:
Amount of bill = $34
Tip = 15%
Amount of tip = 
Amount of tip = 0.15 * 34
Amount of tip = $5.10
Amount after bill = 34 + 5.10 = $39.10
Number of people = William + three friends = 4
Per person share = 
Per person share = $9.775
Rounded to two decimal places
Per person share = $9.78
Hence,
Each person will pay $9.78
If;
A = Adjacent
O = Opposite
H = Hypotenuse
Then,
Sin Ф = O/H
Cos Ф = A/H
Therefore,
(Sin Ф)/Cos Ф) = (O/H)/(A/H) = (O/H)*(H/A) = O/A
Now,
tan Ф = O/A ----
Therefore, it is true that
tan Ф = SinФ/CosФ
Answer:
2500
Step-by-step explanation:
Let the first square number be
then the next square number is
.
The difference between these two consecutive numbers is 99.
This implies that:

We expand to get:

Simplify:


Divide both sides by 2

Therefore the value of the larger perfect number is
.
Answer:
4(2x - 5)
Step-by-step explanation:
Rewrite "20" as 4 * 5
Rewrite "8" as 4 * 2
=4 * 2x - 4 * 5
Factor out common term "4"
=4(2x - 5) <------ Your answer.
