Answer:

5:7

Step-by-step explanation:

For how many red are there blue, is the simple form of this question. In this case the numbers are small for simplifying it but if you wanted to you could do 2.5:3.5 its the same thing, also 10:14 would be right as well as long as the numbers are proportionate. For the smaller simplification i just divided both numbers in half and for the second i doubled them

Shtirlitz [24]

Attendance with the higher ticket price is ...

PROVE :<br><br>sin^2(-300°).cos^2 (120)+ cos^2(-240 ).sin^2(390)=1/4​
leva [86]

Step-by-step explanation:

\sin {}^{2} ( - 300)  \cos {}^{2} (120)  +  \cos {}^{2} ( - 240)  \sin {}^{2} (390)  =  \frac{1}{4}

\sin {}^{2} (60)  \cos {}^{2} ( {}^{} 120)  +  \cos {}^{2} (120)  \sin {}^{2} (30)

\frac{3}{4}  \frac{1}{4}  +  \frac{1}{4}  \frac{1}{4}

\frac{3}{16}  +  \frac{1}{16}  =  \frac{4}{16}  =  \frac{1}{4}
