What would be the solution to 45x - 180 ≤720 be?

2 answers:

7 0

X < or equal to 20

Explanation: We take 180 and add it to 720 to get 900 then with the 45x we divide it we do not flip the signs because 45x is not negative and then we get x is less than or equal to 20

A cone is placed inside a cylinder. The cone has half the radius of the cylinder, but the height of each figure is the same. The

Feliz [49]

Answer:

$\frac{11}{12}\pi r^{2}h\ units^{3}$

Step-by-step explanation:

we know that

<em>Te volume of the cone is equal to</em>

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=(r/2)\ units$

substitute

$V=\frac{1}{3}\pi (r/2)^{2}h$

$V=\frac{1}{12}\pi r^{2}h$

<em>Te volume of the cylinder is equal to</em>

$V=\pi r^{2}h$

we know that

To find the volume of the space remaining in the cylinder after the cone is placed inside it, subtract the volume of the cone from the volume of cylinder

$\pi r^{2}h-\frac{1}{12}\pi r^{2}h=\frac{11}{12}\pi r^{2}h\ units^{3}$

Can any one please help me under this? I need to know which option indicates that 3 goes after 5and between 7,12and 5 then how t

Archy [21]

"3 va después de 5 y entre 7 y 12" = "3 goes after 5, and between 7 and 12"

This eliminates A and D (3 is not between 7 and 12 in either choice).

"5 va antes de 12 y entre 7 y 3" = "5 goes after 12, and between 7 and 3"

This eliminates C (5 is not between 7 and 3).

So the correct sequence is B.

Answer:1,750,000,000

Step-by-step explanation:first the number ten to the fifth power is 1,000,000 then times five is 5,000,000. Then the number ten to the negative fifth power is 50 times seven is 350. 5,000,000 times 350 is 1,750,000,000

Decide whether the rates are equivalent.

Gnom [1K]

Answer:

The rates are equal.

Step-by-step explanation:

To compare these rates, convert them to a unit rate. Divide both the numerator and denominator by the denominator. If you were to express 126 points every 3 games as a fraction:

$\frac{126}{3}$

Now, divide both the top and the bottom by 3:

$\frac{126\div3}{3\div3}=\frac{42}{1}=42$

That is a unit rate of 42 points per game.

Next, do the same thing for the other rate:

$\frac{210}{5}=\frac{210\div5}{5\div5}=\frac{42}{1}=42$

This is also a unit rate of 42 points per game, so the rates are equal.
