Use the Pythagoras theorem:-

diagonal^2 = 5^2+5^2 = 50
diagonal = sqrt 50 = 7.1 inches to nearest tenth

It is given that the plate is a square.

Therefore, let us represent the side of the square by the variable, "a".

Therefore, it is given to us that: $a=5$ inches.

Now, we have to find the diagonal of the square. We know that the diagonal, $d$ of a square is given by the formula:

$d=a\sqrt{2}$

Applying the above formula to our case we get the diagonal to be as:

$d=5\sqrt{2}\approx7.07$ inches.

Therefore, the length of the diagonal to the nearest tenth of an inch is:

$d=7.1$ inches.

The symmetry of a hyperbola with a center at (h, k) only occurs at y = k. True or False

Vikki [24]

A hyperbola with a center at (0, 0) can be defined as x²/a² − y²/b² = ±1.
The statement "The symmetry of a hyperbola with a center at (h, k) only occurs at y = k" is false, because a hyperbola have many different orientations.
It doesn't have to be symmetric about the lines y = k or x = h.

to arrive at 2000 liters of 60% saline solution the attendant has to mix a 90% and a 40% saline solution. How many liters of eac

CaHeK987 [17]

Answer:

800 liters of 90% saline solution and 1200 liters of 40% saline solution should be used.

Step-by-step explanation:

Given:

At 2000 liters of 60% saline solution the attendant has to mix a 90% and a 40% saline solution.

Now, to find the number of liters of saline solution each should be used.

Let the liters of 90% saline solution mix be $x.$

And let the liters of 40% saline solution mix be $y.$

So, the total number of liters:

$x+y=2000.$

$y=2000-x\ \ \ ....(1)$

Now, the total percentage of saline solution:

$90\%\ of\ x+40\%\ of\ y=60\%\ of\ 2000$

$\frac{90}{100}\times x+\frac{40}{100}\times y=\frac{60}{100}\times 2000$

$0.9x+0.4y=1200$

Substituting the value of $y$ from equation (1) we get:

$0.9x+0.4(2000-x)=1200$

$0.9x+800-0.4x=1200$

$0.5x+800=1200$

Subtracting both sides by 800 we get:

$0.5x=400$

Dividing both sides by 0.5 we get:

$x=800.$

The liters of 90% saline solution mix = 800.

Now, substituting the value of $x$ in equation (1) to get the liters of 40% saline solution:

$y=2000-x$

$y=2000-800$

$y=1200.$

Thus, the liters of 40% saline solution = 1200.

Therefore, 800 liters of 90% saline solution and 1200 liters of 40% saline solution should be used.

which is a pair of dependent events? spinning a spinner one time and then spinning it a second time flipping a quarter and then

Sphinxa [80]

<h2>Answer and explanation:</h2>

Two events are said to be dependent on each other, if the outcome of the first thing affects the outcome of the second thing in such a way that the probability changes.

Here, the right answer will be = removing a marble from a bag, not putting it back, and then removing a second marble.

Explanation:

Lets suppose there were 10 marbles in the bag at the first place. Now, you removed one marble and did not put it back. So, remaining marbles will be 9. Now, if again you choose a marble, you have 9 marbles to choose from. We can see that probability changes with the event that occurred at first place.

So, this is the right answer.

Rest options are simultaneous one. They are not dependent in any way.
