Answer:
Step-by-step explanation:
The Law of Cosines: c2 = a2 + b2 − 2ab cos(C)
the law of sines is: (sinA/a) = (sinB/b) = (sinC/c)
Answer:
1. 4x - y is less than or equal to 4 and 2x - 2y is less than or equal to 3
Step-by-step explanation:
Blue line:
y > 4x - 4
y - 4x > -4
4x - y < 4
Test point: (0,0)
4(0) - 0 = 0 < 4
Red line:
y > x - 1.5
2y > 2x - 3
2x - 2y < 3
Test point: (0,0)
2(0) - 2(0) = 0 < 3
Answer:
it is 1:5
Step-by-step explanation:
The table shows the amount of red paint that can be added to different amounts of white paint while making a custom paint color:
Paint Color
Quarts of Red Paint Quarts of White Paint
4 20
5 25
7 35
8 40
Which statement is true about the
ratio of red paint to white paint in the paint color?
it is 1:16
it is 16:1
it is 5:1
it is 1:5
Ratio of red paint to white paint in the paint color = 4 : 20
= 4/20
= 1/5
= 1 : 5
Ratio of red paint to white paint in the paint color = 1 : 5
Ratio of red paint to white paint in the paint color = 5 : 25
= 5/25
= 1/5
= 1 : 5
Ratio of red paint to white paint in the paint color = 7 : 35
= 7/35
= 1/5
= 1 : 5
Ratio of red paint to white paint in the paint color = 8 : 40
= 8/40
= 1/5
= 1 : 5
