Answer:
65.9 ft
Step-by-step explanation:
The Law of Sines tells us the relationship between an angle and the opposite side. We are given the angle opposite the given side, but we need the angle opposite the side of interest.
__
<h3>third angle</h3>
The sum of angles in a triangle is 180°, so the measure of the angle at the balloon is ...
angle C = 180° -75° -60° = 45°
<h3>ground distance</h3>
Then the distance between Amaya and Rochelle (c) is ...
c/sin(C) = r/sin(R)
c = r×sin(C)/sin(R) = (90 ft)×sin(45°)/sin(75°)
c ≈ 65.8846
Amaya and Rochelle are about 65.9 feet apart.
So we need to represent the problem using an equation
900 = the original pile of bricks (x) + 25% more - 40% (original + 25% extra)
900 = x + .25x - .4(x + x*.25)
900 = x + .25x - .4x - .1x
900 = .75x
x = 1200
Answer:
D
Step-by-step explanation:
I think its D or the last choice because distributive property is when you break the equation down it to parts.
Hope this helps!
Answer:
Unorginized sorry
Step-by-step explanation:
Don't understand.
2.8 - 0.6(x + 2) = 2x + 2(x - 0.2)...distribute thru the parenthesis
2.8 - 0.6x - 1.2 = 2x + 2x - 0.4.....simplify
1.6 - 0.6x = 4x - 0.4....add 0.6x to both sides, add 0.4 to both sides
1.6 + 0.4 = 4x + 0.6x ..simplify
2 = 4.6x...divide both sides by 4.6
2 / 4.6 = x...simplify
0.43 = x...(thats rounded, and we need it as a fraction....so it is :
43/100 <==
