Find the dimensions of a rectangle, length 7m less than three times the width and the area of the rectangle is 66m^2.

zhuklara [117]

We know: length of a rectangle is 7m less than three times the width.

So let's set the length to l, width to w.

And we can get that l = 3w-7.

We also know that the area of the rectangle is 66 m^2.

Thus, l*w= 66.

So we have:

function 1: l=3w-7

function 2: l*w=66

plug function 1 to 2.

(3w-7)*w=66

3w^2-7w-66=0

w=6 and -11/3.

And the width of a rectangle can not be negative.

So: w=6.

Plug w=6 back to function 1 or 2, either way is correct and can give you the length. In this case, I will plug it back to function 1.

l=3*6-7=11.

So: the width of the rectangle is 6, and the length of the rectangle is 11.

Flying against the wind, an airplane travels 3060 kilometers in 3 hours. Flying with the wind, the same plane travels 7560 kilom

cluponka [151]

Answer:

The speed of plane against wind S 1 = 1020 kmph And

The speed of plane with wind S 2 = 1260 kmph

Step-by-step explanation:

Given as :

The distance of airplane against the wind = D 1 = 3060 km

The time taken in against the wind = T 1 = 3 hours

The distance of airplane with the wind = D 2 = 7560 km

The time taken in with the wind = T 2 = 6 hours

Now, Speed of plane against the wind = $\frac{Distance}{Time}$

So, S 1 = $\frac{D 1}{T 1}$

Or, S 1 = $\frac{3060}{3}$ = 1020 kmph

Similarly

Speed of plane with the wind = $\frac{Distance}{Time}$

Or, S 2 = $\frac{D 2}{T 2}$

Or, S 2 = $\frac{7560}{6}$ = 1260 kmph

Hence The speed of plane against wind S 1 = 1020 kmph And

The speed of plane with wind S 2 = 1260 kmph Answer
