Answer:
880
Step-by-step explanation:
225 pages, its correct answer i did the math
180/80
x /100
cross multiply;
180*100=18,000
divide with the amount left
18,000/80=225
If d = rt, then you plug in. D = 6(4) = 24.
24 miles. If you need a picture of this work, let me know.
Answer:
2236.77 feets
Step-by-step explanation:
From the attached picture, we are to find x, which is the vertical depth of the submarine.
Using trigonometry based on the illustration in the diagram:
Sinθ = opposite / hypotenus
Sinθ = x (depth of submarine) / distance from ship (4000)
Hence,
Sinθ = x / 4000
θ = 34°
Sin34 = x / 4000
0.5591929 * 4000 = x
2236.7716 = x
Hence, depth of submarine = 2236.77 feets
Answer:
<h3>C. -51/7=-7.28</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
7x/3+2=-15
7x/3+2-2=-15-2 (First, subtract 2 from both sides.)
-15-2 (Solve.)
-15-2=-17
7x/3=-17
3*7x/3=3(-17) (Next, multiply 3 from both sides.)
3(-17) (Solve.)
3(-17)=-51
7x=-51
7x/7=-51/7 (Then, divide by 7 from both sides.)
-51/7 (Solve.)
-51/7=-7.28
x=-51/7=-7.28
So, the final answer is (C.) x=-51/7=-7.28.
