6 times 5 is 30 and since its 6 per hour you just do it to five :)

When a plane flies into the wind, it can travel 3000 ml in 6 h . When it flies with the wind, it can travel the same distance in

jeka94

Answer:

plane: 550 mph
wind: 50 mph

Step-by-step explanation:

If p and w represent the speeds of the plane and wind, respectively, the speed into the wind is ...

p - w = (3000 mi)/(6 h) = 500 mi/h

And, the speed with the wind is ...

p + w = (3000 mi)/(5 h) = 600 mi/h

Adding these two equations gives us ...

2p = 1100 mi/h

p = 550 mi/h . . . . . . . divide by 2

Then the wind speed is ...

w = 600 mi/h - p = (600 -550) mi/h

w = 50 mi/h

The rate of the plane in still air is 550 mi/h; the rate of the wind is 50 mi/h.

What is the approximate value of R in the equation below? (76.4)(.32)(R-112)+(.35)(20R+435)=54

givi [52]

(76.4)(0.32)(R - 112) + (0.35)(20R + 435) = 54
24.448(R - 112) + 7R + 152.25 = 54
24.448R - 2738.176 + 7R + 152.25 = 54
31.448R - 2585.926 = 54
31.448R = 54 + 2585.926
31.448R = 2639.926
R = 2639.926/31.448
R = 83.9457

Ray BD bisects angle ABC. Ray BE bisects angle ABD, and Ray BF bisects angle EBD. If angle ABE = 20 degrees, find the measure of

Mars2501 [29]

An angle bisector is a straight line that divides a given angle into two equal measures. Thus the measure of angle FBC is $50^{o}$ .

A line that divides a given measure of angle into two equal measures is referred to as an angle bisector. This makes the two angles produced by the bisector to be congruent.

Thus from the given question, we have;

<ABD + <DBC = < ABC (addition property of a bisected angle)

<ABE + <EBD = <ABD (addition property of a bisected angle)

<EBF + <FBD = <EBD (addition property of a bisected angle)

Given that angle ABE = $20^{o}$ , thus;

<ABE = <EBD = $20^{o}$

Then,

<EBF + <FBD = $20^{o}$

<EBF = <FBD = $10^{o}$

Such that;

<FBC = <FBD + <DBC

= $10^{o}$ + 2<ABE

= $10^{o}$ + $40^{o}$

<FBC = $50^{o}$

Therefore, the measure of angle FBC is $50^{o}$ .
