Answer:

scale factor 3 is the answer.

Step-by-step explanation:

Length = 18 in

Breadth = 3 in

height = 10 in

Volume of cuboid = l × b × h

V = 18 × 3 × 10

V = 540 in³

540 in³ is the original volume. The volume needs to be tripled, so multiply the original volume with 3

V = 540 × 3 = 1620 in³

∴ 1620 in³ will be the new volume if it's tripled and the scale factor is 3.

soldier1979 [14.2K]

Answer:

28.9°

Step-by-step explanation:

This is a Trigonometry question

From the above, question,

The horizontal distance = Adjacent = 29 feet

The distance of the kite from the ground = Opposite= 14 feet

We solve using the Trigonometric function of Sine

sin θ = Opposite/Adjacent

sin θ = 14/29

θ = arc sin (14/29)

θ = 28.865727415°

Approximately = 28.9°

Therefore, the angle measure of x = 28.9°

t/5 = 2.9
For the first step, I would multiply both sides by 5, to get rid of the fraction.

That will leave
t = 14.5

So with what you have on your screen, I would drag “x” and “5” to both sides of the equation.
