There are two black queens in a standard deck, so the probability is 2/52 or 1/26.

If instead you know you pulled a black card from the deck and you’re wondering what the probably is that it’s a queen, then it’s 2/26, since there are still 2 black queens, but only 26 black cards.

A kite with a string 50 meters long makes an angle of elevation of 58o with the ground, assuming the string is straight, how hig
Sunny_sXe [5.5K]

An angle of elevation of 58 degrees with the ground means that the angle started at the x-axis and terminates on the first quadrant region through a counter clockwise direction. Imagining a triangle, the string of the kite becomes the hypotenuse, the angle 58 degrees is the angle between the hypotenuse and the ground, and the height of the kite is the side opposite to the angle.

Therefore, we can calculate for the height of the kite using the sin function:

sin θ = opposite side / hypotenuse

sin 58 = opposite side / 50 m

opposite side = 50 m * sin 58

opposite side = 42.4 m

<span>Therefore the kite is about 42.4 m above the ground.</span>

olga2289 [7]

Answer:

Matias divided 7.6 by 10 raised to the power of -2.

Step-by-step explanation:

Given : Matias preformed an operation with 7.6 and a number. He ended up moving the decimal point in 7.6 two places to the left.

To find : Matias divided 7.6 by 10 raised to the power of ?

Solution :

Matias preformed an operation with 7.6 and a number.

He ended up moving the decimal point in 7.6 two places to the left we have to multiply it with 0.01

i.e. 7.6\times 0.01=\frac{7.6}{100}=0.076

So, Matias divided 7.6 by 10 raised to the power of -2.

PLease help me on this one? &lt;3
MariettaO [177]

Answer:

A. (1, 0)


Reason:

When the first equation is graphed: y <u><</u> x + 1, the left side of the line is shaded and when the second equation is graphed: y <u><</u> x^2 -3x, the bottom is shaded.

The green section does not contain solutions. So D is automatically out.

The red section does not contain solutions as well. So C is automatically out.

For choice B, the point goes out of the shaded blue section, so that's out also.

As for choice A its in the blue shaded section, which makes that answer correct.

(when the two equations are within each other and combine a color, then whatever points is within the shaded part is the right answer)
