Answer:

4 Miles per hour.

Step-by-step explanation:

Since he slowed down to 11 MPH at the slow car, We cab then use that as a baseline. They turned off the highway and slowed another 7 MPH, so we just subtract 7 from 11 to get 4 MPH.

What’s the volume of a cylinder with a radius of 6ft and height of 14ft? pls show work

Daniel [21]

Answer:

Given -

radius of cylinder = 6 ft
height of cylinder = 14 ft

Now ,

$volume = \pi \: r {}^{2} h \\ = > \frac{22}{\cancel{7}} \times 6 \times\cancel{ 14} \\ \\ = > 22 \times 6 \times 2 \\ = > 264 \: ft {}^{3}$

hope helpful~

Solve for u. 4u=10.24. Please answer thanks :)

ivolga24 [154]

Answer:

Simplifying

4u = 10.24

Solving

4u = 10.24

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Divide each side by '4'.

u = 2.56

Simplifying

u = 2.56

23. The pilot of a small private plane can look forward and see the control tower for a small airstrip.

Alex73 [517]

Answer:

Altitude of the plane is 0.5 miles.

Step-by-step explanation:

From the figure attached,

An airplane A is at height h miles observes a small airstrip at D and a factory at F, 4.8 miles apart from D.

Angle of depressions for the airstrip is 13.1° and the factory is 4.1°.

We have to calculate the airplane's altitude h.

From ΔABF,

tan4.1 = $\frac{AB}{BF}=\frac{h}{(x+4.8)}$

h = 0.07168(x + 4.8) -----(1)

From ΔABD,

tan13.1 = $\frac{h}{x}$

h = 0.2327x -----(2)

From equation (1) and (2),

0.07168(x + 4.8) = 0.2327x

0.2327x - 0.07168x = 4.8×0.07168

0.161x = 0.344

x = $\frac{0.344}{0.161}=2.14$ miles

From equation (2),

h = 0.2327×2.137

h = 0.4972 miles

h ≈ 0.5 miles

Therefore, 0.5 miles is the altitude of the plane.
