Step-by-step explanation:

let the length and breadth's ratio be 4x and 3x

Given, 

area of rectangle = 192 in²

we know,

Area of rectangle = L × B/w 

after inserting the values in the formula we got,

→ 4x × 3x = 192 

→ 12x² = 192

→ x² = 192/12 = 16

→ x² = 16

→ x = √16 = 4

→ x = 4

therefore , length and breadth/width are,

length = 4x = 4×4 = 16

width = 3x = 3×4 = 12

hence length is 16 in. and width is 12in.

hope this answer helps you dear.....take care and may u have a great day ahead!

Answer:

7.2111(4 decimal places)

Step-by-step explanation:

a squared by b squared=c squared

36 + 16 is 52, so then you need to square root 52 which is 7.2111 to 4 decimal places. I hope you benefit from this. Cheers

A hot air balloon rising vertically is tracked by an observer located 5 miles from the lift-off point. At a certain moment, the

Zigmanuir [339]

Answer:

Step-by-step explanation:

aThe person and the hot air balloon form a right triangle, with the lift-off point as the vertex that form the right angle. If you were to try to solve for the height of the balloon, you would need to use tangent to do so:

tanθ = opp/adj = y/x

y = xtanθ

What this problem ultimately wants to know, is how the distance of the balloon is changing with respect to time: dy/dt. So we need to take the derivative of the above equation (you need to product rule to do so):

dy/dt = (dx/dt)tanθ + xsec2θ(dθ/dt)

We need to find out values for all of the variables:

The observer is not moving, therefore dx/dt = 0.

The observer is standing 4 miles away from the lift-off point, so x = 4.

The angle between the horizontal and the observer's line of sight is π/3, therefore θ = π/3.

The rate of change for the angle, dθ/dt, is 0.1.

Just plug all the numbers in:

dy/dt = (0)tan(π/3) + (4)sec2(π/3)(0.1)

dy/dt = 0 + 1.6

dy/dt = 1.6 mi/min

A cylinder has a diameter of 10 units. Its radius is ____ units. Of its height is _______ twice its radius, its height is units.

SpyIntel [72]

Answer:

Height is 10 units

Volume is 785 cubic units

Step-by-step explanation:

We are given;

Diameter of a cylinder as 10 units

But, radius = d/2

= 5 units

Height is twice its radius,

Thus, Height = 10 units

We can get the volume;

Volume of a cylinder = pir²H

Taking pi to be 3.14

Then;

Volume = 3.14 × 5²× 10

= 785 cubic units

Thus, the volume of the cylinder is about 785 cubic units
