Answer:
a) 80 ibs
b) 40 ibs
Step-by-step explanation:
Let X be the pound of the high quality bean at $6.50
(120-x) will be the pound of the cheaper bean at $2.50
6.5x + 2.5(120 - x) = 5.17(120)
6.5x + 300 - 2.5x = 620.4
Collect like terms
6.5x - 2.5x = 620.4 - 300
4x = 320.4
x = 320.4/4
x= 80.1
x = 80 ibs(to the nearest pounds)
For the cheaper bean we have 120 -x
= 120 - 80
= 40 ibs
Sarah would blend 80 ibs of quality bean and 40 ibs of cheaper bean
Answer:
The sine ratio is the ratio between the opposite side over hypotenuse. The cosecant ratio is the ratio between the hypotenuse over the opposite side, therefore cosecant is the reciprocal of sine.
To find a missing angle using sine, you would need to use the inverse of sine. For example, if the sine was 
, to find the angle you would need to find sin⁻¹ of which is x = sin⁻¹ (0.75). Therefore x equals approximately 49°.
Answer:
B
Step-by-step explanation:
y = (x + 1)/x
xy = x + 1
xy - x = 1
x(y - 1) = 1
x = 1/(y - 1)
Interswitch variables
f^-1(x) = 1/(x - 1)
$0. She got the $40 ring and then gave it back. 40-40=0.
