Answer:
w = 40 miles per hour
r = 300 miles per hour
Step-by-step explanation:
We add w with the wind and subtract w against the wind
r+w = 340 miles per hour
r - w = 260 miles per hour
Add the two equations together to eliminate w
r+w = 340 miles per hour
r - w = 260 miles per hour
----------------------------------------
2r = 600
Divide by 2
r = 300 miles per hour without the wind
Now find w
r+w = 340
300 + w = 340
Subtract 300
w = 340-300
w = 40 miles per hour

Step-by-step explanation:
volume of cone=1/3×π×4²×10=160/3 π cm³
Answer:
96cm
Step-by-step explanation:
For a triangular prism we find the surface area by doing base times height/ length times width, but since we have a triangle we would have to divide the answer we get by 2. Once we get all the sides we then would have to add them all up.
<h3>front back top </h3>
3X4X1/2 ( HINT: ITS THE SAME AS THE FRONT) 7X5
12X1/2 6= back 35= top
6= front
<h3>Bottom side <u><em>
since we are done finding all</em></u> </h3>
7X4 3X7 <em><u>of the area of the shapes we add </u></em>
28= bottom 21= side <u><em>all of them together.</em></u>
Surface area= 6+6+35+28+21= <u><em>96 cm</em></u>
Answer: 14
Step-by-step explanation:
Okay so it asks in all, which means morning distance + afternoon distance
We got the afternoon distance so now we have to find the morning one
it says the afternoon distance (6), is 25% less than the morning distance.
Which means the afternoon distance is 0.75 of the morning distance.
so 0.75x = 6, x = 6/0.75 = 8
Then you add 8 to 6 to get 14
One thousand three hundred fifty is one way
