Answer:
b ≈ 4.2
Step-by-step explanation:
Using the tangent ratio in the right triangle, that is
tan50° = 
= 
= 
( multiply both sides by b )
b × tan50° = 5 ( divide both sides by tan50° )
b = 
≈ 4.2 ( to the nearest tenth )
2x = 10√3
=> x = 10√3 / 2
=> x = 5√3
hence missing side of triangle is 5√3
Answer:
Yes, he has enough
Step-by-step explanation:
1 pint = 16 onces
4.5 * 16 = 72
Yes, he has enough
Ok lets say
popcorn = x and
drinks = y
Jacob: 2x + 3y = 18.25
Zachary: 4x + 2y = 27.50
ok now you have to use these 2 equations to get the answer
4x + 2y = 27.50 ---> 2y = 27.50 - 4x ---> y = 13.75 - 2x
2x + 3y = 18.25
2x + 3(13.75-2x) = 18.25
2x + 41.25 - 6x = 18.25
-4x + 41.25 = 18.25
-4x = -23
x = 5.75 <u><em>One bag of popcorn is $5.75</em></u><em />
4x + 2y = 27.50
4(5.75) + 2y = 27.50
23 + 2y = 27.50
2y = 4.50
y = 2.25 <u><em>One drink is $2.25</em></u><em />
Your answer is -3...if i did this right.
