Answer:
The number of pounds of City Roast Columbian coffee they should buy is 1 and the number of pounds of French Roast Columbian coffee they should buy is 11.
Step-by-step explanation:
Let
x ----> the number of pounds of a City Roast Columbian coffee
y ---> the number of pounds of a French Roast Columbian coffee
we know that
-----> equation A
----> equation B
Solve the system of equations by graphing
The solution is the intersection point both graphs
The solution is the point (1,11)
therefore
The number of pounds of City Roast Columbian coffee they should buy is 1 and the number of pounds of French Roast Columbian coffee they should buy is 11.
Answer:
A. You can not use the Pythagorean theorem because you would need the length of at least two sides but the triangle only provides the length of one.
B. x ≈ 7 ft. y ≈ 6 ft.
Step-by-step explanation:
Sin(51) =
Sin(51)*9 = x
x = 6.99431
x ≈ 7 ft.
Now you can use the Pythagorean theorem.
= 32
b = 5.65685
y ≈ 6 ft.
Or, continue to use the cosine.
Cos(51) =
Cos(51)*9 = y
y = 5.66388
y ≈ 6 ft.
Answer Check
We know c = 9 ft.
The third decimal place is the third one to the left; using the example 4.4965, the 6 is the third place (or the thousandth's place). So you would look at the number in front of it (in this case, 5) and if it is 5 or more, you round up. So the answer for this problem is <u>4.497</u>. I hope this helps you!
