Answer:
27.5 square units
Step-by-step explanation:
You want to know the area of the composite shape shown in the graph.
CompositionThe shape can be decomposed into a parallelogram and a triangle. Each has the same base, 5 units.
The parallelogram has a height of 3 units, so its area is ...
A = bh
A = (5)(3) = 15 . . . . square units
The triangle has a height of 5 units, so its area is ...
A = 1/2bh
A = 1/2(5)(5) = 12.5 . . . . square units
The total area of the figure is the sum of the areas of its parts:
total area = (15 units²) +(12.5 units²) = 27.5 units²
The area of the polygon is 27.5 square units.

You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 44 km south and 227 km east. Mt. Rainier is located approximately 56 km east and 40 km south of JBLM. If you are flying at a constant speed of 800 km/hr, how long after you depart JBLM will you be the closest to Mt. Rainier?
Answers
The time JBLM will you be the closest to Mt. Rainier will be 5.12 minutes.
What is Distance?A measurement of the distance between two places along a line or line segment.
The plane's flight route follows the line.
y = -125/135x = -25/27x
The direction of the perpendicular line passing across Mt. Rainier is,
y = 27/25(x -56) -40
In standard form, these two equations are,
25x +27y = 0
27x -25y = 2512
The coordinates at the closest approach are the answers to these two equations:
(x, y) = (33912/677, 31400/677)
The Pythagorean theorem (distance formula) states that the distance d from the origin to this point is as follows:-
d = 1256√(2/677) km
The airplane's speed can be used to convert this distance to time:
1256√(2/677) X 60/800 = 94.2√(2/677) ≈ 5.120019 mins
So, 5.12 minutes after leaving JBLM, Mt. Rainier will be the nearest.

You have a wire that is 35 cm long. You wish to cut it into two pieces. One piece will be bent into the shape of a square. The other piece will be bent into the shape of a circle. Let A represent the total area of the square and the circle. What is the circumference of the circle when A is a minimum?
Answers
The circumference of the circle is 110 m.
What is the circumference of the circle?Let us assume that the wire has been cut into two equal halves thus the radius of the circle would be 35 m/2 = 17.5 m
Then;
C = 2πr
C = circumference
r = radius
"pi" is a mathematical constant approximately equal to 3.14 and "r" is the radius of the circle. If the diameter of the circle is known, the radius can be calculated by dividing the diameter by 2.
C = 2 * 3.142 * 17.5

In ΔVWX, x = 6.4 inches, w = 8.8 inches and ∠W=85°. Find all possible values of ∠X, to the nearest 10th of a degree.
Answers
Using the Law of Cosines, we can write the following equation for triangle VWX:
V^2 = W^2 + X^2 - 2WXcos(W)
Plugging in the given values, we have:
V^2 = (8.8)^2 + X^2 - 2(8.8)(X)cos(85°)
V^2 = 77.44 + X^2 - 15.36X
Solving for X, we can use the quadratic formula:
X = (-(-15.36) ± √((-15.36)^2 - 4(77.44)(1)))/2(1)
X = (15.36 ± √(234.84))/2
So the possible values of X are approximately:
X = (15.36 + 15.32)/2 = 15.34 inches
X = (15.36 - 15.32)/2 = 0.02 inches
Converting the length of X to degrees, we can use the inverse cosine function (arccos) to find the angles:
∠X = arccos(X/V)
For the first value of X (15.34 inches), we have:
∠X = arccos(15.34/V)
Since V is not given, we cannot determine a numerical value for ∠X, but it is safe to say that it will be between 0° and 90°.
For the second value of X (0.02 inches), we have:
∠X = arccos(0.02/V)
Since X/V is very close to 0, the cosine value will be close to 1, so the angle will be close to 0°. To the nearest 10th of a degree, ∠X = 0°.

one third of all the sweets he now has to Amal. All of them end up having the same
number of sweets, Chandran begins with 40 sweets, How many sweets does Balu have
originally?
(4marks
Answers
Answer: Balu originally had 40 sweets.
Step-by-step explanation:
Let x be the number of sweets Balu originally had.
After Amal gives one third of his sweets to Balu, Balu's number of sweets becomes x + (1/3)x = (4/3)x.
After Balu gives one third of his sweets to Chandran, Chandran's number of sweets becomes 40 + (1/3)(4/3)x = 40 + (1/3)x.
After Chandran gives one third of his sweets to Amal, Amal's number of sweets becomes (2/3)x + (1/3)(40 +(1/3)x) = (2/3)x + (1/3)x + 40/3 = (5/3)x + 40/3.
Since all three of them now have the same number of sweets, we can set the number of sweets each of them has equal:
(4/3)x = (5/3)x + 40/3.
Now, we will isolate x by rearranging the equation. Subtracting (5/3)x from both sides, we get:
(4/3)x - (5/3)x = 40/3
Simplifying the left side:
-x/3 = 40/3
Dividing both sides by -1/3:
x = 40
Thus, Balu originally had 40 sweets.

Algebra: let f(x)= 3x+7 f^-1 (x)=
Answers
Answer:
Step-by-step explanation:
To find the inverse of a function, we need to switch the x and y values and solve for y (or x, depending on how the original function is written). The inverse of the function f(x) = 3x + 7 is written as f^-1(x). To find f^-1(x), we can follow these steps:
Replace the function f(x) with y to make it easier to manipulate: y = 3x + 7.
Swap the x and y variables: x = 3y + 7.
Solve for y:
Subtract 7 from both sides to get x - 7 = 3y.
Divide both sides by 3 to get (x - 7) / 3 = y.
Write the inverse function using f^-1(x) instead of y:
f^-1(x) = (x - 7) / 3
So, the inverse of the function f(x) = 3x + 7 is f^-1(x) = (x - 7) / 3.

Answers
The answer is (a) MX + MY. Whether or not X and Y are independent, we cannot simplify (a) or (b) further.
The mean of X + Y is:
E(X + Y) = E(X) + E(Y)
So the answer is not (a) or (b).
(c) is incorrect because the formula given is only true if X and Y are independent, but no such assumption is given in the problem.
(d) is also incorrect because we cannot simply divide the means by the standard deviations to get the standard normal variables, especially when the variables X and Y have different means.
Therefore, the answer is (a) MX + MY.
Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

For students majoring in Hospitality Management, it was determined that 5% have visited 1–10 states, 16% have visited 11–20 states, 45% have visited 21–30 states, 19% have visited 31–40 states, and 15% have visited 41–50 states. Suppose a Hospitality Management student is randomly selected. What is the probability that the student has visited 21 or more states?
A . 0.15
B. 0.21
C. 0.45
D. 0.79
Answers
Answer:
D. 0.79
Step-by-step explanation:
To find the probability that a Hospitality Management student has visited 21 or more states, we need to sum up the probabilities of the categories that represent students who have visited 21 states or more.
The probabilities of the categories are as follows:
Visited 21–30 states: 45% = 0.45
Visited 31–40 states: 19% = 0.19
Visited 41–50 states: 15% = 0.15
So, the total probability of a student having visited 21 or more states is:
0.45 + 0.19 + 0.15 = 0.79.
Therefore, the probability that a Hospitality Management student has visited 21 or more states is 0.79 or 79%.
A local coffee shop is testing out new flavors of coffee: Caramel Apple Latte and Salted Minty Mocha. A poll conducted by the
coffee shop determined that 46 customers preferred only the Caramel Apple Latte, 61 customers chose only the Salted Minty
Mocha, 27 customers chose both flavors, but 18 liked neither flavor. What is the probability that a randomly selected
customer would only like the Caramel Apple Latte?
Answers
The probability that a customer selected randomly would only like Carmel apple is 23/76
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Probability = sample space/ total outcome
sample space is the number of customers that like caramel apple latte only = 46
The total number of customers = 46+61+27+18 = 152
Therefore The probability that a customer selected randomly would only like Carmel apple = 46/152 = 23/76

Joan’s finishing time for the Bolder Boulder 10K race was 1.66 standard deviations faster than the women’s average for her age group. There were 410 women who ran in her age group. Assuming a normal distribution, how many women ran faster than Joan? (Round down your answer to the nearest whole number.)
Answers
Joan completed the race 1.66 standard deviations faster than the typical female of her age group. The standard deviation will be denoted by the symbol “” and the women's average finish time by the symbol “”. Then, Joan's remaining time was plus 1.66.
What is the assuming of normal distribution?The proportion of women who finished the race sooner than Joan. In this case, it is possible to apply the normal distribution.
The percentage of values to the left of z = 1.66 can then be calculated or found using a standard normal distribution table. The number of women who finished the race ahead of Joan is represented by the percentage in the table below.
According to a normal distribution table or calculator, there are approximately 0.9525 numbers to the left of the value z = 1.66.
Therefore, This means that out of the 410 female runners in Joan's age group, about 0.9525 × 410 = 391.23 of them beat her. The final count is 391 women, rounded to the next whole number.
