Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine Rule in Δ XYZ
cosY = 
Here x = 22, y = 20, z = 22, then
cosY = 
= 
= 
, thus
Y = 
( ) ≈ 59.0° ( to the nearest tenth )
4/5 is the same as 80% or .80, so it's larger than 76% and .77
Answer:
m=2, b=2
y=2x+2
The slope is positive, and the equation is proportional.
Answer:
C=25d
Step-by-step explanation:
We write an equation where C or cost is my output and d or days is my input. I should be able to put in any number of days and find the cost. Let's gather some data:
River Ramble
Day 1 $25(1)=25 cost
Day 2 $25(2)=50 cost
Day 3 $25(3)=75 cost
Day d $25(d)=C.
Our equation is C=25d.
