Please Help!! :D Find the value of y.

rjkz [21]

Answer:

$y=2\sqrt{2}$

Step-by-step explanation:

The Pythagorean theorem is a theorem that can be applied to the sides of a right triangle. Please note that a right angle refers to an angle with a measure of (90) degrees. A box around an angle shows that the angle is a right angle, or has a measure of (90) degrees. The Pythagorean theorem states the following,

$a^2+b^2=c^2$

Where (a) and (b) are the legs of the triangle, or the side adjacent to the right angle in the right triangle. (c) is the side opposite the right angle, or the hypotenuse of the triangle. One can apply this theorem to the smallest triangle in the diagram to find (y),

$a^2+b^2=c^2$

Substitute,

$(1)^2+(y)^2=(3)^2$

Simplify,

$(1)^2+(y)^2=(3)^2$

$1+y^2=9$

Inverse operations,

$1+y^2=9$

$y^2=8$

$y=\sqrt{8}$

Take a factor from out of the square root. Remember that a number times itself under the radical is equal to the number. This can be simply stated as the following: ( $\sqrt{a*a}=a$ ),

$y=\sqrt{8}$

$8=2*2*2$

$y=\sqrt{8}$

$y=\sqrt{2*2*2}$

$y=2\sqrt{2}$

There was a triangle ABC with sides 15, 20, and 10. One of the sides of a triangle, which is similiar to ABC is 60. What are the

wlad13 [49]

Answer:

The possible pairs of sides are 90 and 120, 30 and 45, and 80 and 40.

Step-by-step explanation:

We know that 60 is a multiple of 15, 20, and 30, so we multiply by each factor to find all possible pairs: 10x6=60, 20x6=120, and 15x6=90, that gives your first pair, 90 and 120.

We have now multiplied our first factor, 6. Now we need to multiply our second factor, 3: 20x3=60, 15x3=45, and 10x3=30. That gives your second pair, 30 and 45.

Finally, we need to multiply by our 3rd factor, 4: 15x4=60, 20x4=80, and 10x4=40. That gives you your final possible pair, 80 and 40.

I hope this helps :-)

Please help me answer this :) and explain how you got your answer ! ( will give brainslt )

Answer: y = - 0.4 x - 4.5

Step-by-step explanation:

Equation y=mx+b

m is the slope

x is *ANY* x coordinate

y is *ANY* y coordinate

b is y intercept or WHERE the point is on the Y AXIS

Lets look at the given:

Slope (m) is -2/5

Passes through point 15, -9/2

As you can see, the point goes through the Y axis at (-9/2)

Our equation is y = - 0.4 x - 4.5

There are 52 playing cards in a standard deck of cards. If Patrica selects a card at random, what is the probability that it wil

Alisiya [41]

Since there are two black queens out of 52 cards, there is a 2/52 chance of drawing a black queen first. This is equivalent to a 1/26 chance.

Now that we have removed a black queen, there are 51 cards left in the deck. 26 of them are red because we only took away a black card. This means that there is a 26/51 of drawing a red card next.

In order to find the probability of both of these happening, we multiply the two together. 1/26 * 26/51 = 26/1326. This reduces to 1/51. So, there is a 1/51 chance of drawing a black queen, then a red card.
