Answer:
85.84
Step-by-step explanation:
6x4 is the area of 1 rectangle
There r 3 rectangles
6x4 =24
24x3 =72
That’s the area if all the rectangles
There r 2 triangles
(4x3.46)/2 is the area of 1 triangle
=6.92
6.92x2 =13.84
total surface area is all the areas added up
72+13.84
=85.84

The profit equation for the sale of pressure cookers for the company Kitchen Masters is PP = −120pp2 + 19,800pp − 727,450. Which of the following is a sale price for the immersion blenders, p, that will allow Kitchen Masters to achieve a profit, P, of $89,300?
Answers
Where the above factors are given, a sale price of approximately $84 for the immersion blenders will allow Kitchen Masters to achieve a profit of $89,300.
Why is this so?The profit equation for the sale of pressure cookers for the company Kitchen Masters is:
P = −120p² + 19,800p − 727,450
To find the sale price for the immersion blenders, p, that will allow Kitchen Masters to achieve a profit, P, of $89,300,
Let the profit equation = 89,300.
Now, we solve for p:
89,300 = −120p² + 19,800p − 727,450
Adding 727,450 to both sides:
816,750 = -120p² + 19,800p
Dividing both sides by -120:
-6,805 = p² - 165p
Rearrange the equation to make it Quadratic
p² - 165p + 6,805 = 0
Now we can solve for p using the quadratic formula:
p = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = -165, and c = 6,805.
p = (-(-165) ± √((-165)² - 4(1)(6,805))) / 2(1)
p = (165 ± √((27,225 - 27220)) / 2
p ≈ 83.618 or p ≈ 81.382
Therefore, a sale price of approximately $84 for the immersion blenders will allow Kitchen Masters to achieve a profit of $89,300.

A combined total of $33,000 is invested in two bonds that pay 5% and 6.5% simple interest. The annual interest is $2,010.00. How much is invested in each bond?
Answers
Answer: $9,000 is invested in the 5% bond, and $24,000 is invested in the 6.5% bond.
Step-by-step explanation: x + y = 33,000 (the full sum contributed)
We too know that the yearly intrigued earned is $2,010.00, which is the whole of the intrigued earned from each bond. Utilizing the equation for basic intrigued:
intrigued = principal x rate x time
ready to calculate the intrigued earned from each bond:
0.05x (for the 5% bond)
0.065y (for the 6.5% bond)
So we have another condition:
0.05x + 0.065y = 2,010
Presently we have two conditions with two factors, which we are able illuminate utilizing substitution or end.
Let's utilize substitution:
x + y = 33,000 --> y = 33,000 - x
0.05x + 0.065y = 2,010 --> 0.05x + 0.065(33,000 - x) = 2,010
Streamlining:
0.05x + 2,145 - 0.065x = 2,010
-0.015x = -135
x = 9,000
So the sum contributed within the 5% bond is $9,000, and the sum contributed within the 6.5% bond is:
y = 33,000 - x = 33,000 - 9,000 = $24,000

Answers
a) The percent of the scores are between 72 and 87 is 77.45%
b) The probability that a score is greater than 77 is 84.13%
c) The probability that a score is less than 82 or greater than 92 is 52.28%
d) About 5 students scored outside two standard deviations of the mean.
a) To find the percent of scores between 72 and 87, we first need to standardize these scores. We can do this by subtracting the mean (82) and dividing by the standard deviation (5). This gives us:
z = (72 - 82) / 5 = -2
z = (87 - 82) / 5 = 1
We can then use a table of standard normal probabilities (also called a z-table) to find the probability of a score being between -2 and 1. This probability is 0.7745, or 77.45%
b) To find the probability that a score is greater than 77, we again need to standardize the score:
z = (77 - 82) / 5 = -1
Using the z-table, we can find the probability of a score being greater than -1 (which is the same as the probability of a score being less than or equal to 77). This probability is 0.1587, or 15.87% (rounded to two decimal places). To find the probability of a score being greater than 77, we subtract this probability from 1:
P(score > 77) = 1 - P(score <= 77) = 1 - 0.1587 = 0.8413, or 84.13%
c) To find the probability that a score is less than 82 or greater than 92, we can break this into two separate probabilities:
P(score < 82) + P(score > 92)
We can standardize these scores as follows:
z = (82 - 82) / 5 = 0
z = (92 - 82) / 5 = 2
Using the z-table, we can find the probabilities associated with these z-scores:
P(score < 82) = P(z < 0) = 0.5 (from the symmetry of the standard normal distribution)
P(score > 92) = P(z > 2) = 0.0228
Adding these probabilities together gives us:
P(score < 82 or score > 92) = 0.5 + 0.0228 = 0.5228, or 52.28%
d) Two standard deviations from the mean in either direction would be:
82 - (2 x 5) = 72
82 + (2 x 5) = 92
So any score below 72 or above 92 would be considered outside two standard deviations. To find how many students scored outside this range, we need to find the total proportion of scores that fall outside this range and multiply by the total number of scores.
To find the proportion of scores outside the range, we can use the same approach as in part c):
P(score < 72 or score > 92) = P(z < -2 or z > 2) = P(z < -2) + P(z > 2)
Using the z-table, we find:
P(z < -2) = 0.0228
P(z > 2) = 0.0228
Adding these probabilities together gives us:
P(score < 72 or score > 92) = 0.0228 + 0.0228 = 0.0456
So 4.56% of scores fall outside the range of 72 to 92. To find the number of students who scored outside this range, we can multiply this proportion by the total number of scores:
0.0456 x 120 = 5.472 ≈ 5

Answers
The requreid Mona's phone call was 13 minutes long.
Let's let the variable "m" represent the length of the phone call in minutes.
We know that Mona pays $1.00 for the first call of the day plus $0.15 per minute of the call. So the total cost of the call can be represented by the expression:
$1.00 + $0.15m
We also know that Mona paid $2.95 for her first call today. So we can set the expression for the total cost of the call equal to $2.95:
$1.00 + $0.15m = $2.95
To solve for the length of the call in minutes, we can first subtract $1.00 from both sides of the equation:
$0.15m = $1.95
Then we can divide both sides by $0.15:
m = 13

length= 5 in , width= 4 in, height= 3 in
Answers
length, l=16in
width, b=13in
thickness, t=3in
To Find:-
Area of wrapping paper required.
Explanation:-
Since, wrapping paper is to be wrapped over the whole rectangular box.Therefore, we have to calculate the total surface area of the rectangular box.

Therefore, 590 of paper is required to wrap the whole rectangular box.
=700 sq in
= 94 sq in
Step-by-step explanation:
To find the amount of gift paper required to wrap the gift box, we need to find the total surface area of the rectangular prism. The total surface area is the sum of the areas of all six faces of the rectangular prism.
The formula for the surface area of a rectangular prism is:
Surface area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
For the given rectangular prism with dimensions 15 in, 10 in, and 8 in, we have:
l = 15 in, w = 10 in, h = 8 in
Substituting these values into the formula, we get:
Surface area = 2(15)(10) + 2(15)(8) + 2(10)(8)
Surface area = 300 + 240 + 160
Surface area = 700
Therefore, the amount of gift paper required to wrap the gift box is 700 square inches.
For the second part of the question, we need to find the surface area of the rectangular prism with dimensions 5 in, 4 in, and 3 in. Using the same formula, we have:
l = 5 in, w = 4 in, h = 3 in
Surface area = 2(5)(4) + 2(5)(3) + 2(4)(3)
Surface area = 40 + 30 + 24
Surface area = 94
Therefore, the amount of gift paper required to wrap the second gift box is 94 square inches.

$26.24

Answers
A = P(1 + r)^n
where A is the final amount, P is the initial amount, r is the annual interest rate as a decimal, and n is the number of years.
In this case, P = 18.50, r = 0.06, and n = 6. Plugging these values into the formula, we get:
A = 18.50(1 + 0.06)^6
A = 18.50(1.06)^6
A = 18.50(1.4185)
A = 26.23
Therefore, the cost of the all-you-can-eat buffet in 6 years will be approximately $26.23, which is closest to option A.
