0.10r + 0.20b = 24
3r = b + 20....b = 3r - 20
0.10r + 0.20(3r - 20) = 24
0.10r + 0.60r - 4 = 24
0.70r = 24 + 4
0.70r = 28
r = 28/0.70
r = 40 <=== there are 40 reds
0.10r + 0.20b = 24
0.10(40) + 0.20b = 24
4 + 0.20b = 24
0.20b = 24 - 4
0.20b = 20
b = 20/0.20
b = 100 <=== there are 100 blues

I hope this helps
Since the measure of angle 
is 
The measure of its reference angle = 
=
Now we have to compute the value of 
The value of (
) lies in the fourth quadrant. In fourth quadrant, the value of tan is always negative.
So, 
= -1.
Answer:
18 cm
Step-by-step explanation:
The ratio of Actual length (L) to scale length is 27 : 3.6
27 ÷ 3.6 = 7.5
Therefore, actual width (W) = scale width x 7.5
= 2.4 x 7.5
= 18 cm
To obtain an equivalent fraction by multiplying, multiply the whole fraction by any single number. Example: 3/4 multiplied by 3 is 9/12. Those fractions are equivalent.
To obtain an equivalent fraction by dividing, look at the top number and the bottom number. If they both can be divided by a number without it being a decimal, it’s an equivalent fraction. Example: 8/10, both of those numbers can be divided by 2 that isn’t a decimal, 4/5. 4/5 and 8/10 are equivalent
