A + b = 147....a = 147 - b
5.85a + 4.40b = 786
5.85(147 - b) + 4.40b = 786
859.95 - 5.85b + 4.40b = 786
-5.85b + 4.40b = 786 - 859.95
- 1.45b = -73.95
b = -73.95 / -1.45
b = 51 <== she used 51 lbs of type B coffee
Answer:
9600 words in an hour.
Step-by-step explanation:
There are sixty minutes in an hour.
60/6=10
multiply 960 by 10
960*10=9600
The secretary can type 9600 words in 1 hour.

Answer:
Top option / (x ,y) -> (x + 6, y + 6)
Step-by-step explanation:
So we know that RSTU is the original so it will not be the last option (1/4) as it is not getting smaller
To figure out the answer though, we need to figure out the dilation,
See attached photo!
(sorry for sloppy drawing/etc, it is hard on the laptop haha)
Answer:
Step-by-step explanation:
Remark
a is one part of the cosine function. It is termed the adjacent side. The given number (12) is the hypotenuse of a right triangle. The reference angle is given as 25. You have all you need to solve for a
Givens
<B = 25o
AB = 12
a = a
Equation
Cos(B) = adjacent side / hypotenuse
Solution
Cos(25) = adjacent side / 12 Multiply both sides by 12
12*cos(25) = adjacent side
cos(25) = 0.90631
12*0.906331 = adjacent side
10.87 = adjacent side
Answer
a = 10.9
