Alla and balla together drink 750ML of water. Of alla drinks 50% more than balla how much does Alla drink

Akimi4 [234]

Answer:

450 ml.

Step-by-step explanation:

Let x be the amount of water drank by Alla and y be the amount of water drank by Balla.

We have been given that Alla and Balla together drink 750 ML of water. We can represent this information as:

$x+y=750...(1)$

We are also told that Alla drinks 50% more than Balla. We can represent this information as:

$x=1.5y...(2)$

From equation (1) we will get,

$y=750-x$

Upon substituting this value in equation (2) we will get,

$x=1.5(750-x)$

Upon distributing 1.5 to right hand side of the equation we will get,

$x=1125-1.5x$

Upon adding 1.5x to both sides of equation we will get,

$x+1.5x=1125-1.5x+1.5x$

$2.5x=1125$

Let us divide both sides of our equation by 2.5.

$\frac{2.5x}{2.5}=\frac{1125}{2.5}$

$x=450$

Therefore, Alla drank 450 ml of water.

What is the value of sec theta given the diagram below?

marishachu [46]

Answer:

$\sec \theta=-\sqrt{5}$

Step-by-step explanation:

The hypotenuse is $h^2=6^2+3^2$

$h^2=36+9$

$h^2=45$

$h=\sqrt{45}$

$h=3\sqrt{5}$

The terminal side of $\theta$ is in the second quadrant.

In this quadrant; the secant ratio is negative.

$\sec \theta=-\frac{hypotenuse}{adjacent}$

$\sec \theta=-\frac{3\sqrt{5}}{3}$

$\sec \theta=-\sqrt{5}$

Hello!

n<span>≤-1/2 means that n is less than the open circle, because an open circle means the variable can not be equal to that point. so your answer is: D

I hope this helps, and have a nice day.

Answer:

I believe it would be 0 and up

Step-by-step explanation:

|x + 3|

|3 + 3|

3 - 3 = 0

and X can be any number higher than two so it would go up by one each time. 0,1,2,3 etc..
