Hi there!

351.68 is already rounded to the nearest hundredth. The digit in the hundreds place is 8.

Hope this helps! Tell me if you meant something else ;)

Ok I have a question it says, " Ella can read 2 pages in 3 minutes. How long will it take her to read 45 pages?". So I just don'

Vaselesa [24]

Answer:

67.5

Step-by-step explanation:

this gives you the basis of the problem, 2 pages every 3 minutes, so that means that you have to divide 45 by 2, this will give you 22.5

then you multiply by 3 because 22.5 is how many sets of 2 Ella has to read, and if we remember every set of 2 pages takes 3 minutes, so 22.5 times 3 is 67.5, but if you want the answer in time it would be 67 minutes and 30 seconds because a minute is 60 seconds and half of that is 30

What is the length of the altitude of the equilateral triangle below

AVprozaik [17]

Answer

Find out the altitude of the equilateral triangle .

To proof

By using the trignometric identity.

$tan\theta = \frac{Perpendicular}{base}$

As shown in the diagram

and putting the values of the angles , base and perpendicular

$tan 60^{\circ} = \frac{a}{4\sqrt{3}}$

$tan 60^{\circ} = \sqrt{3}$

solving

$\sqrt{3} = \frac{a}{4\sqrt{3}}$

$a = \sqrt{3}\times 4 \sqrt{3}$

As

$\sqrt{3}\times \sqrt{3} = 3$

put in the above

a = 4 × 3

a = 12 units

The length of the altitude of the equilateral triangle is 12 units .

Option (F) is correct .

Hence proved

find the value of solid figure not including hole cutout. Round to two decimal places. Cube figure is 12 feet long with 4 ft cut

Artemon [7]

Answer:

1577.20 ft³

Step-by-step explanation:

Cube of length = 12 ft = a

Hole diameter which is cutout = 4 ft = d

Hole radius which is cutout = 4/2 =2 ft = r

Volume of the cube = a³

⇒Volume of the cube = a×a×a

⇒Volume of the cube = 12×12×12

⇒Volume of the cube = 1728 ft³

The hole cut out will be in the shape of a cylinder

Volume of cylinder = πr²h

⇒Volume of cylinder = π×2²×12

⇒Volume of cylinder = 150.79 ft³

Now volume of the solid figure with hole cut out is

Volume of the cube - Volume of cylinder

=1728 - 150.79

=1577.20 ft³

∴ Volume of solid figure not including hole cutout is 1577.20 ft³
