<span>What’s
9 discount to 4
let’s analyze the given data. 9 is the 100% and 4 is the discount. Thus we have
5 left.
=> 9 – 4 = 5
To get the answer, let’s divide the discount amount to the total amount which is
4 and 9
=> 4 / 9 = 0.44
Since we already have the decimal value, let’s multiply this by 100%
=> 0.44 *100% = 44%
Thus the discount is 44%. And what is remaining is:
=> 100% - 44% = 66%</span>
Lin should aim the ball at 7.8 feet away from point B
From the question (see attachment), we have the following equivalent ratios:

This is so because triangles ABE and DCE are similar triangles.
Such that:



So, we have:


Make CE the subject in 

Substitute 20 - BE for CE in 

Express as ratio

Cross multiply

Open bracket

Collect like terms


Divide both sides by 41

Hence, she should aim at 7.8 feet away from point B

Answer:
-6
Step-by-step explanation:
Substitute as in replace "w" with 4
10-4(4)
Multiply -4 and 4
-16
10-16=-6
Hope this helps
Adjacent side to angle 60º=2/3
opposite side to angle 60º=b
hypotenuse=a
cos 60º= adjacent side / hypotenuse
cos 60º=(2/3) / a
a=(2/3) / cos 60º=(2/3) / (1/2)=4/3
tan 60º= opposite side / adjacent side
tan 60º=b / (2/3)
b=(2/3)*tan 60º=(2/3)* √3=2√3 /3
Answer:
a=4/3
b=2√3 /3
