Answer:
b ≈ 7.8
Step-by-step explanation:
using the law of sines
∠ A = 180° - 105° - 40° = 180° - 145° = 35° , then
= 
( cross- multiply )
b × sin35° = 7 × sin40° ( divide both sides by sin35° )
b = 
≈ 7.8 ( to the nearest tenth )
Answer:
A=(16 -5 0 -9)-(3 -4 -11 24)
Step-by-step explanation:
The solution process for any algebraic expression is to "undo" what is done to the variable. Here, matrix A has (3 -4 -11 24) added to it. The next step is to undo that addition, by subtracting that amount from both sides of the equation. The result is ...
A = (16 -5 0 -9)-(3 -4 -11 24)

Answer:
okay, so 1 1/6 can be converted to 7/6.
2 3/8 can be converted to 19/8
now find a common denominator, which is 24
7/6 would turn into 28/24
19/8 would turn into 57/24
now add! 28+57= 85/24
85/24

Answer:
4
Step-by-step explanation:
25/100 x 80/1 = 20/1
80 - 20 = 60
30/100 x 80/1 = 24/1
80 - 24 = 56
60-56=4
Answer:
35%
