What is 500000 and 60000000 as a decimal

1 answer:

3 0

The only way to make a decimal out of either of those numbers is to write a decimal point with some zeros after it.

500,000 = 500,000.000

60,000,000 = 60,000,000.00000

etc.

Bad White [126]

It would take 4 hours for both trains to meet.

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

Let t represent the time at which both trains meet, and d represent the distance covered by train A, hence:

For train A:

100 = d / t

t = d/100

For train B:

200 = (1200 - d) / t

t = (1200 - d) / 200

d/100 = (1200 - d)/200

2d = 1200 - d

3d = 1200

d = 400 km

t = 400 / 100 = 4 hours

It would take 4 hours for both trains to meet.

find the surface area of a right regular hexagonal pyramid with sides 3 cm and slant heights 6cm. show all of your work.

DedPeter [7]

Answer:

The surface area of right regular hexagonal pyramid = 82.222 cm³

Step-by-step explanation:

Given as , for regular hexagonal pyramid :

The of base side = 3 cm

The slant heights = 6 cm

Now ,

The surface area of right regular hexagonal pyramid = $\frac{3\sqrt{3}}{2}\times a^{2} + 3 a \sqrt{h^{2}+ 3\times \frac{a^{2}}{4}}$

Where a is the base side

And h is the slant height

So, The surface area of right regular hexagonal pyramid = $\frac{3\sqrt{3}}{2}\times 3^{2} + 3 \times 3 \sqrt{6^{2}+ 3\times \frac{3^{2}}{4}}$

Or, The surface area of right regular hexagonal pyramid = $\frac{3\sqrt{3}}{2}\times 9 + 9 \sqrt{36+ 3\times \frac{9}{4}}$

Or, The surface area of right regular hexagonal pyramid = 23.38 + 9 × $\frac{171}{4}$

∴ The surface area of right regular hexagonal pyramid = 23.38 + 9 × 6.538

I.e The surface area of right regular hexagonal pyramid = 23.38 + 58.842

So, The surface area of right regular hexagonal pyramid = 82.222 cm³ Answer
