45²

This says "forty five squared"

Try saying it aloud, it may help to hear it :)

This basically just means to multiply 45 by itself twice.

So, what's 45 times 45?

Its 2025!

Hope I helped! :)

${45}^{2} = 45 \times 45$
Does this help?

Galactic Rotation Speed. We are located about 27,000 light-years from the galactic center and we orbit the center about once eve

Alexxandr [17]

Answer:

speed = 796142.197 km/hr

Step-by-step explanation:

solution

we consider here orbit around galactic center is circular so

circumference formula will be here

circumference C = 2πr ........1

here we know r = 27000

circumference C = 2 π × 27000

C = 169560 light year

we travel 169560 light year in 230000000 years

so distance will be

distance = $\frac{169560}{230000000}$

distance = 0.00073721 light year/year

and we know 1 year = 8760 hours

so 1 light year = 9.46027 × $10^{12}$ km

sped of moving is

speed = 0.00073721 × 9.46027 × $\frac{10^{12}}{8760}$ km/hr

speed = 796142.197 km/hr

You have been asked to design a rectangular box with a square base and an open top. The volume of the box must be 1536cm3. Deter

Katen [24]

Answer:

The dimensions of the box are:

Length = 11.53cm

Breadth = 11.53cm

Height = 11.53cm

Step-by-step explanation:

The volume of the box can be calculated with this formula:

The volume of the box = area of square base X height of the box.

We are given that the length of one side of the square base is = x cm, and its height is h cm.

Area of square base = $x^{2}cm^{2}$

The surface area of the box will be minimized if the height of the box, is the same as its length. hence, we can take the height of the box to be x cm also.

In this case, the volume of the box will be $x^{3}=1536cm^{3}$

from this, $x =3\sqrt{1536}= 11.53cm$

There fore, the box has its length, height, and width all having the same values.

The dimensions of the box are:

Length = 11.53cm

Breadth = 11.53cm

Height = 11.53cm
