Answer:

In a very simple way, it can be verified that the equation is correct by making the divisions that the fractions represent, and checking that the result of these divisions is the same, as presented by the equation.

That is, by making the division of 1/2 and adding it to the division of 3/8, the result of said sum should be equal to 4/10 and 2/5.

Therefore, I will perform this calculation to verify if the equation is correct:

1/2+3/8 =4/10=2/5

0.5 + 0.375 = 0.4

0.875 = 0.4

As we can see, the equation is absolutely false, since the sum of 1/2 + 3/8 does not result in 4/10 or 2/5 (which are the same fraction, but simplified) but 7/8 (7 / 8 = 0.875).

the height of the first rectangle ( 30 ) over the height of the other rectangle ( 3 ) is 30/3 and equals 10

the length of the first rectangle ( 60 ) over the length of the second rectangle ( 6 ) is 60/6 and equals 10

the ratio of the sides of both rectangles are equivalent therefore the are similar

A right circular cylinder has a height of 22 1/4 ft and a diameter 2 2/5 times its height. What is the volume of the cylinder? E

Triss [41]

Answer:

The volume of cylinder is:

49806.06 ft^3

Step-by-step explanation:

We are given a right circular cylinder with:

Height(h)= $22\frac{1}{4}ft=\dfrac{89}{4}ft$

and a diameter is $2\frac{2}{5}$ times it's height.

i.e. $\dfrac{12}{5}$ times it height.

i.e. the diameter is given as:

$\dfrac{12}{5}\times \dfrac{89}{4}=\dfrac{267}{5}ft.$

We know that the radius of cylinder is half the diameter.

Hence, radius(r) of cylinder is:

$\dfrac{1}{2}\times \dfrac{267}{5}\\\\=\dfrac{267}{10}$

The volume(V) of cylinder is given by:

$V=\pi r^2h$

$V=3.14\times (\dfrac{267}{10})^2\times \dfrac{89}{4}\\\\V=\dfrac{19922423.94}{400}\\\\V=49806.06ft^3$

Hence, the volume of cylinder is:

49806.06 ft^3

Explanation:
________________________________________________________

24 = 250/100 * x ;

24 = 2.5 x ;

↔ 2.5 x = 24 ;

2.5 x / 2.5 = 24/ 2.5 ;

x = 9.6 ;

The answer is: " 9.6 inches <span>" .
