Tina uses a $50 gift certificate to buy a pair of pajamas for 17.97 a necklace for 25.49 and 3 pairs of socks that each cost the
Furkat [3]
The overall cost is $50.33. you now subtract out the prices you know. The easiest way to do that is to add them up; 17.97+25.49. That is 43.46.

The next step is to subtract 43.46 from 50.33. 50.33-43.46=6.87. That is the price of all the pairs of socks put together.

to find out how much one pair is, you then divide 6.87 by 3. That is 2.29.

The answer is $2.29

I hope this helps!

Answer:

5391.76

Step-by-step explanation:

We have a rectangle and 2 semicircles

First find the area of the rectangle

A = l*w

A = 44*88= 3872

Then we know that 2 semicircles = 1 circle

The area of a circle is

A = pi r^2

The diameter is 44 so the radius is 22

A = pi * 22^2

A = pi484

A =1519.76

Add the areas together

1519.76+3872

5391.76

a man casts a 3 feet long shadow. if the suns rays strike the ground 62°, what is the height of the man?
Romashka [77]

Answer:

h = 3*tan(62) where h is the height

Step-by-step explanation:

You basically have a right triangle.  the standing man is the vertical line, the shadow is the horizontal line and the 62 degrees is the angle betweenthe horizontal line and the hypotenuse.

So, relative to the angle we have the adjacent angle and opposite.  What uses those?  Tangent.  tan(x) = opp / adj

tan(62) = h/3

h = 3*tan(62) where h is the height

Answer:

Option D is correct.

(2x^5y^2)^3= 8x^{15}y^6

Step-by-step explanation:

Power of product property:

  • (x^m)^n = x^{mn}
  • (ax)^m = a^m \cdot x^m

Let the equation: (2x^5y^2)^3

Using power of products Property on given equation:

(2x^5y^2)^3 = 2^3 \cdot (x^5)^3 \cdot (y^2)^3 = 8 \cdot x^{15} \cdot y^6 = 8x^{15}y^6

Therefore, the only option D of an equation which shows the correct use of power of Products property is,  (2x^5y^2)^3= 8x^{15}y^6
