The correct option is (d) i.e. The area of the given parallelogram will be 36 ft²

What is a Parallelogram ?

A quadrilateral with two sets of parallel sides is known as a parallelogram. A parallelogram has equal-sized opposite sides and opposite angles. Additionally, the interior angles on the same side of the transversal are additional. 360 degrees is the total of all interior angles.

The term "parallelepiped" refers to a three-dimensional shape with parallelogram-shaped faces. The base (one of the parallel sides) and height (the distance from top to bottom) of a parallelogram determine its area, respectively. The length of each of a parallelogram's four sides determines its perimeter.

Given : base of parallelogram = 4+2= 6 ft

            height of the parallelogram = 6ft

We know that, area of a parallelogram = base × height

So, Area of the given parallelogram = 6 × 6

                                                           = 36 ft²

Hence, The correct option is (d).

The pet store donated 5 percent of $7,900 to hospitals.

How to find the percentage of a number?

To find the percentage of a number, we can use the formula:

(percent) = (part / whole) x 100

Where "part" is the portion we want to find the percentage of, and "whole" is the total amount. The result gives us the percentage of the part relative to the whole.

Calculation of the percentage donated to hospitals -

In this problem, we are given that a pet store donated a percentage of every sale to hospitals, and we need to find out what percentage of $7,900 was donated. We are also given that the total donation amount was $395.

To solve this problem, we can use the percentage formula, with the part being the donation amount ($395) and the whole being the total sales ($7,900).

Substituting these values into the formula, we get:

(percent donated) = (395 / 7,900) x 100

Simplifying the fraction, we get:

(percent donated) = 0.05 x 100

Multiplying 0.05 by 100 gives us 5

Therefore, the pet store donated 5% of $7,900 to hospitals.

Answer: P = 15N - 2t

Step-by-step explanation:

To find "P", we get rid of the last thing done to the subject (P).

Here it is "/15"

So we get rid of it by doing the opposite, remember, we do this to both sides.

Step 1:

             N = P - 2t/ 15

      x15 ↓                 ↓ ×15

              15N = P - 2t

Step 2:

Now, the last thing done to the "P" is "-2t". So we get rid of it by adding 2t to both sides.

                 15N = P - 2t

             +2t ↓             ↓ +2t

                  15N + 2t = P

So, we got P by its own, so we have made P the subject of the formula!

              N = P - 2t/ 15

      x15 ↓                 ↓ ×15

               15N = P - 2t  

           +2t ↓            ↓ +2t

               15N + 2t = P

               P = 15N - 2t

The area of the shaded region is the sum of the area of the semicircle and the area of the rectangle, giving us an answer of 32.13m².

A semicircle is considered as a two-dimensional shape that is half of a circle. It is formed by drawing a line from the center point of a circle to one of its edges. The line becomes the diameter of the semicircle, and the two sides of the semicircle form an arc.

The shaded area in the diagram is the region which is bounded by the semicircle and the rectangle.

To find the area of this shaded region, we first need to find the area of the semicircle and the area of the rectangle. The area of the semicircle is derived from the formula A = (πr²)/2, where r is the radius of the semicircle. The radius of the semicircle can be found by dividing the length of the rectangle by 2, as the semicircle is half of the rectangle, giving us a radius of 3m.

Therefore, the area of the semicircle is 14.13 m². The area of the rectangle is the length of the rectangle multiplied by its width, which is 6m×3m = 18m².

Finally, the area of the shaded region is the sum of the area of the semicircle and the area of the rectangle, giving us an answer of 32.13m².

The answer of the given question based on the mutually exclusive event is the probability of event R3 given event Q is 0.37.

Probability is  branch of mathematics that deals with  study of random events or phenomena. It is concerned with quantifying the likelihood of an event or a set of events occurring. Probability is often expressed as a number between 0 and 1, with 0 indicating an impossible event and 1 indicating a certain event.

Using Bayes' theorem, we can find the probability of event R3 given event Q as follows:

P(R3|Q) = P(Q|R3)*P(R3)/P(Q)

so, by using the law of total probability:

P(Q) = P(Q | R1) * P(R1) + P(Q | R2) * P(R2) + P(Q | R3) * P(R3)

Substituting the given values, we get:

P(Q) = (0.5 * 0.05) + (0.6 * 0.3) + (0.2 * 0.65)

= 0.0425 + 0.18 + 0.13

= 0.3525

Now, substituting the given values for P(Q | R3) and P(R3), we get:

P(R3 | Q) = (0.2 * 0.65) / 0.3525

= 0.37

Therefore, the probability of event R3 given event Q is 0.37.

Substituting the values shows that the point that lies on the exponential function are

We can use substitution to determine which ordered pairs lie on the graph of the exponential function f(x) = 3(4)^2x.

For the first ordered pair (0, 3),

f(0) = 3(4)^2(0) = 3(1) = 3

(0, 3) lies on the graph of the exponential function.

For the second ordered pair (1, 48)

f(1) = 3(4)^2(1) = 3(16) = 48

(1, 48) lies on the graph of the exponential function.

For the third ordered pair (1/2, 12),

f(1/2) = 3(4)^2(1/2) = 3(4) = 12

(1/2, 12) lies on the graph of the exponential function.
