The answer is: The surface area of the sphere.

The explanations for this exercise is shown below:

By definition, the surface area of a sphere is four times the area of a circle.

You have that the area of a circle is:

A=\pi r^{2}

Where r is the radius of the circle.

Therefore, to calculate the surface area of a sphere with radius r, you only need to multiply the equation shown above by four, as following:

SA=4\pi r^{2}

kogti [31]

She makes a minimum monthly payment of 62.52 dollars. Then the correct option is B.

<h3>What is the percentage?</h3>

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

May currently has a balance of $1,817.43 on her credit card.

If she must make a minimum monthly payment of 3.44% of her total balance.

Then the minimum payment will be given as

Minimum payment = 0.0344 × 1817.43

Minimum payment = 62.519 ≅ 62.52

More about the percentage link is given below.

The end points of one diagonal of a rhombus are (0,-8) and (8,-4). If the coordinates of the 3rd vertex are (1,0), what are the
Nitella [24]
Diagonal of a Rhombus are perpendicular & intersects in their middle point:
Assume the diagonals intersects in H

A(0,-8), B(1,-0), C(8,-4) & D(x, y) are the vertices of the rhombus and we have to calculate D(x, y)

Consider the diagonal AC. Find the coordinate (x₁, y₁) H, the middle of AC
Coordinate  (x₁, y₁) of H, middle of A(0,-8), C(8,-4)
x₁ (0+8)/2 & y₁=(-8-4)/2 ==> H(4, -6)
Now let's calculate again the coordinate of H, middle of the diagonal BD
B(1,-0), D(x, y)
x value = (1+x)/2 & y value=(y+0)/2 ==> x= (1+x)/2 & y=y/2
(1+x)/2 & y/2 are the coordinate of the center H, already calculated, then:
H(4, -6) = [(1+x)/2 ,  y/2]==>(1+x)/2 =4 ==> x=7 & y/2 = -6 ==> y= -12

Hence the  coordinates of the 4th vertex D(7, -12)

Which ordered pair is the solution to the system of equations below using the elimination method?
kodGreya [7K]
<span>15x-3y=27
5x+4y=14

multiply (2nd) equation by (3)
15x + 12y = 42

</span>15x - 3y=27
15x + 12y = 42
-------------------substract
-15y = -15
     y = 1

15x-3y=27
15x-3(1)=27
15x - 3 = 27
15x = 30
    x = 2

so now you have x = 2, y =1

answer <span>D. (2,1)</span>
