The perimeter of a rectangle, P, is given by P = 2L + 2W, where L is its length and W is its width. What is the perimeter of a rectangle of length 9 ft and width 13 ft?


Answer 1
Answer: Answer: 44 ft

Step-by-Step Explanation:

Length (L) = 9 ft
Width (W) = 13 ft
Perimeter (P) = 2L + 2W

Substitute values of ‘L’ and ‘W’ :-

= 2L + 2W
= 2(L + W)
= 2(9 + 13)
= 2(22)
= 2 * 22
=> 44

Hence, Perimeter (P) = 44 ft

Xpress 8.54545454545... as a rational number, in the form pq where p and q are positive integers with no common factors.


To express the repeating decimal 8.54545454545... as a rational number, we can use the concept of infinite geometric series. The rational number equivalent is 282/33.

To express the repeating decimal 8.54545454545… as a rational number, we can use the concept of infinite geometric series. Let x = 8.54545454545…, then multiplying x by 100 gives 100x = 854.54545454545…. Next, subtracting the original x equation from the 100x equation eliminates the repeating decimals, giving 99x = 846. Dividing both sides by 99 results in x = 846/99. Simplifying the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3, gives the final answer: x = 282/33.

If you mean p/q, then this is how you do it:

x = (846)/(99) = (94)/(11)

Therefore your final answer is 94/11, where p is 94 and q is 11.

Find sin (A-B) if sin A = 4/5 with A between 90 and 180 and if cos B = 3/5 with B between 0 and 90



sin(A-B) = 24/25

Step-by-step explanation:

The trig identity for the differnce of angles tells you ...

sin(A -B) = sin(A)cos(B) -sin(B)cos(A)

We are given that sin(A) = 4/5 in quadrant II, so cos(A) = -√(1-(4/5)^2) = -3/5.

And we are given that cos(B) = 3/5 in quadrant I, so sin(B) = 4/5.

Then ...

sin(A-B) = (4/5)(3/5) -(4/5)(-3/5) = 12/25 + 12/25 = 24/25

The desired sine is 24/25.

y = 7/2 or 3.5

Kristen owns a bakery and is making a cake for a wedding. The dimensions of the cake are shown below. Answer each of the questions below.What is the frosted area of the top cake? (Round to the nearest tenth)

What is the frosted area of the bottom cake? (Round to the nearest tenth)

What is the total surface area of cake that will be frosted?




Step-by-step explanation:

The total revenue that is gained from the sales of the cakes is determined by multiplying the number of cakes by the price. If we let x be the number of $1 that should be deducted from the price and y be the total revenue,

                              y = (25 - x)(100 + 5x)


                             y = 2500 + 25x - 5x²

We get the value of x that will give us the maximum revenue by differentiating the equation and equating the differential to zero.

                            dy/dx = 0 = 25 - 10x
