Komok [63]

Answer:

Minor earthquakes occurred in the country in the last year were 2326.

Step-by-step explanation:

Given:

In the last year, a total of 2727 earthquakes occurred in the country.

Of these, 85.3 % were minor tremors with magnitudes of 3.9 or less on the Richter scale.

Now, to find the minor earthquakes occured in the country last year.

Total earthquakes occurred in the country = 2727.

The percent of minor earthquakes = 85.3%.

Now, to get the number of minor earthquakes:

85.3% of 2727.

$=\frac{85.3}{100} \times 2727.$

$=\frac{232613.1}{100}$

$=2326.131$

The number of minor earthquakes nearest whole number = 2326.

Therefore, minor earthquakes occurred in the country in the last year were 2326.

Six pyramids are shown inside of a cube. The height of the cube is h units. Six identical square pyramids can fill the same volu

MAXImum [283]

Answer:

(A)The height of each pyramid is One-half h units.

Step-by-step explanation:

Height of the Cube = h units

Volume of the Cube $=h^3 $ cubic units$

If Base of the cube =Base of the square pyramid

Base of the square pyramid = h units

$\text{Volume of a Pyramid}=\dfrac{1}{3}*Base Area*Height$

$\text{Volume of One Pyramid}=\dfrac{1}{3}*h^2*Height$

$\text{Volume of Six Pyramids}=6*\dfrac{1}{3}*h^2*Height\\=(2h^2*Height)\:cubic\:units$

Since Volume of the Cube = Volume of Six Square Pyramids

Then:

$2h^2*Height=h^3\\Height=\dfrac{h^3}{2h^2} \\$Height of each pyramid =\dfrac{1}{2}h \:Units$

How do you multiply fractions with cross canceling

AVprozaik [17]

3 9
_ * _
15 6

Compare diagonally to see if they the 2 numbers simplify.

Ex:

3 and 6 Simplify to 1 and 2 because they are both multiples of 3.

9 and 15 Simplify to 3 and 5 because they are both multiples of 3 as well.

Now our fractions are

1 3
_ * _
5 2

Now multiply across to get your final fraction/answer
