the Museum of Science in Boston displays a running total of the U.S. population. on may 11, 1993, the total was increasing at the rate of 1 person every 14 sec. the displayed population figure at 3:45 PM. that day was 257,313,431. assume that the relative growth rate is constant.
A) what is the relative growth rate per year (365 days)?
B) at this rate, what will the U.S population be at 3:45 Pm Boston tiem in May 11, 2001
The relative growth rate per year is approximately 22521.43 people per year. The U.S. population at 3:45 PM Boston time on May 11, 2001, will be approximately 275,333,002 people.
Explanation:The relative growth rate per year can be found by converting the rate of 1 person every 14 seconds to the rate per year. There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day, so there are 60 * 60 * 24 = 86400 seconds in a day. There are 365 days in a year, so the rate per year is (1 person / 14 seconds) * (86400 seconds / 1 day) * (365 days / 1 year) = 22521.4286 people per year. Therefore, the relative growth rate per year is approximately 22521.43 people per year.
To determine the U.S. population at 3:45 PM Boston time on May 11, 2001, we need to calculate the number of seconds between May 11, 1993, and May 11, 2001, at 3:45 PM. There are 365 days in a year and 24 hours in a day, so there are 365 * 24 = 8760 hours in a year. Since May 11, 1993, to May 11, 2001, is 8 years, there are 8 * 8760 = 70080 hours between the two dates. There are 60 minutes in an hour and 60 seconds in a minute, so there are 60 * 60 = 3600 seconds in an hour. Therefore, there are 70080 * 3600 = 252288000 seconds between the two dates. The population increase rate is 1 person every 14 seconds, so the population increase during this time period is 252288000 / 14 = 18020571.43 people. Adding this to the initial population of 257,313,431 gives a total population of 257,313,431 + 18020571.43 = 275,333,002.43. Therefore, the U.S. population at 3:45 PM Boston time on May 11, 2001, will be approximately 275,333,002 people.
A retailer has determined that the cost C of
ordering and storing x units of a product is
c=6x+900000/x
(a) Write the expression for cost as a single fraction.
(b) Determine the cost for ordering and storing - x=240
units of this product. ...?
In part (a), the expression for cost as a single fraction is (6x^2 + 900000x) / x. In part (b), we substitute x = 240 and simplify the expression to find the cost for ordering and storing 240 units of the product.
Explanation:(a) To write the expression for cost as a single fraction, we need to combine the terms in the numerator. The numerator is 6x + 900000 and the denominator is x. To combine the terms, we multiply 6x by x to get 6x^2, and then add 6x^2 + 900000x in the numerator. Therefore, the expression for cost is (6x^2 + 900000x) / x.
(b) To determine the cost for ordering and storing x = 240 units of this product, we substitute x = 240 into the expression for cost. Plugging in x = 240, we have (6(240)^2 + 900000(240)) / 240. Simplifying this expression gives us the cost for ordering and storing 240 units of the product.
The cost function C = 6x + 900000/x can be written as a single fraction as C = (6x² + 900000) / x. When x = 240, the cost for ordering and storing the units is calculated to be $5190.
The cost C of ordering and storing x units of a product is given by the formula C = 6x + 900000/x. To write this expression as a single fraction, we can find a common denominator and combine the two terms:
C = (6x²+ 900000) / x
For part (b), to determine the cost for ordering and storing x = 240 units of this product, we substitute 240 for x in the expression:
C = (6(240)² + 900000) / 240
Which simplifies to:
C = (6(57600) + 900000) / 240
C = (345600 + 900000) / 240
C = 1245600 / 240
C = 5190
Therefore, the cost for ordering and storing 240 units of this product is $5190.

Please help.. what is the function rule for the perimeter P of a building with a rectangular base if the width w is two times the length L?
A.) P=2L B.) P=6L C.) P=6w
Answer:
B.) P = 6LStep-by-step explanation:
The perimeter is the sum of all sides of the figure. In this case, the perimeter of the rectangle would be: [tex]P=W+L+W+L[/tex]; where [tex]W[/tex] is width, and [tex]L[/tex] is length.
According to the problem, the width is two times the length:
[tex]W=2L[/tex]
Replacing this relation in the perimeter equation, we have:
[tex]P=2W+2L\\P=2(2L)+2L\\P=4L+2L\\P=6L[/tex]
Therefore, the perimeter is six times the length of the rectangle. The correct answer is B.

Which of the following shows the correct value of 50
A. 4 < 50 < 5
B. 7 < 50< 8
C. 8 <50 < 9
D. 10 < 50 < 11
Answer:
None of the options is correct
Step-by-step explanation:
It is important to know that he expression a < x < b means that x is greater than a and less than b. So, for finding the correct value let's analyse each option.
A. 4 < 50 < 5
50 is greater than 4 but it is not less than 5, so, option A is incorrect.
B. 7 < 50 < 8
50 is greater than 7 but it is not less than 8, so, option B is incorrect.
C. 8 < 50 < 9
50 is greater than 8 but it is not less than 9, so, option C is incorrect.
D. 10 < 50 < 11
50 is greater than 10 but it is not less than 11, so, option D is incorrect.
Thus, none of the options is correct.
The correct inequality that should show the value of 50 is 49 < 50 < 51, but based on the provided options and context, all are incorrect. If choosing the closest correct answer, it would be 'C. 8 < 50 < 9', acknowledging that it is still incorrect because 50 is not less than 9. Hence, option C.
The student's question is about determining the correct inequality that shows the value of 50 within two consecutive integers. When comparing numbers, we need to find two consecutive integers between which the number 50 falls. The correct inequality that illustrates this is D. 10 < 50 < 11, as 50 is greater than 10 and less than 11. Considering context, this seems to be a typo, since 50 cannot be between 10 and 11. The correct answer should logically be none of the above, as 50 is actually between 49 and 51, making all the provided options incorrect. However, if the intention was to find which of the provided options is closest to being correct, then the answer would be C. 8 < 50 < 9, as 50 is greater than 8 but certainly not less than 9. It is important to note that this question involves an error in the provided options.

the three sides of a triangle have lengths 3x, 2x+4, and 5x-8. Find the value of x that makes the triangle equilateral.
Answer:
x=4
Step-by-step explanation:
The value of x that makes the triangle equilateral is 4
How to determine the valueFor an equilateral triangle, all three sides must be equal in length. In this case, the sides are represented by 3x, 2x + 4, and 5x - 8.
To find the value of x that makes the triangle equilateral, set up an equation:
3x = 2x + 4 = 5x - 8
Now, solve for x:
3x = 2x + 4.
Subtract 2x from both sides:
x = 4
Now, check if x = 4 satisfies the other two parts: 2x + 4 and 5x - 8.
For 2x + 4:
2(4) + 4 = 8 + 4 = 12
For 5x - 8:
5(4) - 8 = 20 - 8 = 12
Since all three expressions are equal to 12, the value of x = 4 makes the triangle equilateral.

Abdul is making a map of his neighborhood. He knows the following information:
His home, the middle school, and high school are all on the same street.
His home, the elementary school, and his friend's house are on the same street.
The distance between his home and the middle school is 3 miles.
The distance between his high school and the middle school is 6 miles.
The street between the middle school and elementary school is parallel to the street between his friend's home and the high school.
What theorem can Abdul use to determine the remaining distances for his map?
Pythagorean Theorem
Midsegment Theorem
Triangle Proportionality Theorem
Side-Angle-Side Similarity Theorem
Answer:
Triangle Proportionality Theorem
Step-by-step explanation:
Just took the test xD
Abdul can use the Pythagorean Theorem to calculate the straight-line distances on his map, utilizing the formula a² + b² = c² for right triangles created by the intersections of his neighborhood's streets.
To determine the remaining distances for his map, Abdul can apply the Pythagorean Theorem. The streets in question form right angles at their intersections, as implied by the parallel streets mentioned. Thus, if Abdul needs to find the distance between two points that form a right angle with another point (essentially creating a right triangle), he can use the formula a² + b² = c², where a and b are the legs (sides forming the right angle) of the triangle and c is the hypotenuse (the side opposite the right angle).
For example, if Abdul wants to find the straight-line distance (hypotenuse) between his home and the high school, and he knows the distance to the middle school (3 miles) and the distance from the middle school to the high school (6 miles), he can use the Pythagorean Theorem to calculate this. Assuming his home, the middle school, and the high school form a right triangle, the formula becomes: 3² + 6² = c², which after calculations gives c =
√(3² + 6²).
Therefore, the correct answer is pythagoras theorm.

Convert the equation to polar form.
2x=2y ...?
To convert 2x = 2y into polar form, replace x with r cos(theta) and y with r sin(theta), then simplify, resulting in the polar equation cos(theta) = sin(theta) or theta = pi/4 + kpi, where k is an integer.
To convert the equation 2x = 2y to polar form, we need to use the relationship between Cartesian coordinates (x, y) and polar coordinates (r, (theta)). The transformations are given by x = r cos(theta) and y = r sin(theta).
Starting with our original equation 2x = 2y, we can substitute the transformations into the equation, which gives us 2(r cos(theta)) = 2(r sin(theta)). We can divide both sides by 2 to simplify, which results in r cos(theta) = r sin(theta). Since r cannot be 0 (because then both x and y would be 0, which does not satisfy the original equation), we can divide both sides by r, leading to cos(theta) = sin(theta). This equation implies that tan(theta) = 1. When tan(theta) equals 1, theta can be written as theta = arctan(1) or theta = pi/4 + kpi, where k is an integer representing the multiple full rotations around the circle.

A. 44%
B. 29%
C. 22%
D. 57%
Answer:
B. 29%
Step-by-step explanation:
if there is a 30% chance of sun tomorrow and a 20% chance of wind and no sun.
what is the probability that it is windy, given that it is not sunny.
A: it is not sunny
P(A)=0.7 (since, chance of being sunny=30% then chance of not being sunny=70%)
B:it is windy
A∩B:it is windy and not sunny
P(A∩B)=0.2 (chance=20%)
B/A:it is windy given that it is not sunny
Baye's theorem states that:
P(A∩B)=P(B/A)×P(A)
0.2=P(B/A)×0.7
⇒ P(B/A)= 2/7=0.286
≈ 29%
Hence, probability that it is windy, given that it is not sunny is:
B. 29%
The probability that a dessert sold at a certain cafe contains chocolate is 73%. The probability that a dessert containing chocolate also contains nuts is 25%. Find the probability that a dessert chosen at random contains nuts given that it contains chocolate. Round to the nearest tenth of a percent.
The probability that a dessert chosen at random contains nuts given that it contains chocolate is approximately 0.34.
Explanation:To find the probability that a dessert chosen at random contains nuts given that it contains chocolate, we can use the formula for conditional probability:
P(N|C) = P(C and N) / P(C)
We are given that the probability that a dessert contains chocolate is 73% or 0.73, and the probability that a dessert containing chocolate also contains nuts is 25% or 0.25. Therefore, P(N|C) = 0.25 / 0.73 ≈ 0.34, rounded to the nearest tenth of a percent.
The probability that a dessert contains nuts given it contains chocolate is approximately 34.3%.
Probability of a dessert containing chocolate = 73% (0.73)
Probability of a dessert containing nuts given it contains chocolate = 25% (0.25)
Probability that a dessert contains nuts given it contains chocolate
Let C be the event that the dessert contains chocolate and N be the event that it contains nuts.
Therefore, the probability that a dessert chosen at random contains nuts given that it contains chocolate is approximately 34.3%.

Jennifer broke open her piggy bank and found 83 coins in nickels and dimes. If she had $6.95 in all, how many coins of each has she?
Jennifer has 27 nickels and 56 dimes.
Let's use the variables n and d to represent the number of nickels and dimes Jennifer has, respectively.
We can set up two equations based on the given information:
n + d = 83 (equation 1)0.05n + 0.10d = 6.95 (equation 2)Now, we can solve this system of equations.
We can rewrite equation 1 as n = 83 - d and substitute it into equation 2:
0.05(83 - d) + 0.10d = 6.95
4.15 - 0.05d + 0.10d = 6.95
0.05d = 6.95 - 4.15
0.05d = 2.80
d = 2.80 / 0.05
d = 56
Substituting the value of d back into equation 1, we find n = 83 - 56 = 27.
Therefore, Jennifer has 27 nickels and 56 dimes.
