You could draw a square, rectangle, parallelogram, and other shapes that make four sides or more.
Step-by-step explanation:
sin 0 = opposite ÷ hypothenus
sin 0 = 3 / 5
3 / 5 = x / 15
5 × n = 15
n = 3
x = 3 × 3 = 9
y = use pythagoras
= 12
tan 0 = opposite ÷ adjacent
tan 0 = 9/12
Answer: it would take them 4.24 hours
Step-by-step explanation:
It takes Emily eight hours to paint her house. Her unit rate of working in terms of hours would be 1/8
Mike can paint the same area in nine hours. Mike's unit rate of working in terms of hours is 1/9
If both of them can work together,Then, the work would take lesser time because they would be working together at their own unit rates. This means that the rates are additive. Their combined rates would be 1/8 + 1/9
Let t be the time it takes them to finish the work together. This means that their unit rate of working together will be 1/t. Therefore,
1/8 + 1/9 = 1/t
17/72 = 1/t
17t = 72
t = 72/17
t = 4.24
Okay, so let's say that "y" is the total amount she pays for these movies, and "x" is the number of nights she has the movie. This would be the function which represents this scenario:
y = 1.50+1.25x
1.5 stands for the money you paid upfront, and 1.25 for each night she kept the movie, with x standing for that each night
