The volume of a rectangular prism varies jointly with the length and width of the figure when the height remains constant. The volume of a rectangular prism is 672 cubic centimeters. The figure has a length of 8 centimeters and a width of 14 centimeters. A second prism has a length of 12 centimeters and a width of 8 centimeters. What is the volume of the second prism? 576 cubic centimeters 768 cubic centimeters 784 cubic centimeters 1,344 cubic centimeters
1st Prism = 8*14 = 112
672/112 = 6
2nd prism = 8*12=96
96*6 = 576 cubic cm
answer is 576 cubic centimeters
Answer:
The correct option is 1.
Step-by-step explanation:
The volume of a rectangular prism varies jointly with the length and width of the figure when the height remains constant.
Let the height of both rectangular prism be h cm.
The volume of a prism is
[tex]V=l\times b\times h[/tex]
Where, l is length, b is breadth or width and h is height.
The volume of a rectangular prism is 672 cubic centimeters. The figure has a length of 8 centimeters and a width of 14 centimeters.
[tex]672=8\times 14\times h[/tex]
[tex]672=112h[/tex]
Divide both sides by 112.
[tex]\frac{672}{112}=h[/tex]
[tex]6=h[/tex]
The value of h is 6 cm. It means the height of both prism is 6 cm.
A second prism has a length of 12 centimeters and a width of 8 centimeters. So, the volume of second prism is
[tex]V=12 \times 8\times 6[/tex]
[tex]V=576[/tex]
The volume of second prism is 576 cubic centimeters. Therefore the correct option is 1.
Bret is starting a business selling handmade necklaces. He has decided to invest and initial amount of $387 for advertising and materials cost seven dollars for each necklace he makes. Bret can sell his creations for $10 per necklace.once he makes and sells a certain number of necklaces he will break even with identical expenses and sales. How many necklaces would that take? What would the total expenses and sales be then?
To break even, Bret would need to make and sell 40 necklaces, with a total expense of $15,760 and total sales of $400.
Explanation:To determine the number of necklaces Bret needs to make and sell to break even, we need to consider his initial investment and the expenses and sales associated with each necklace.
First, let's calculate the total expenses for each necklace: $7 (materials cost) + $387 (initial investment) = $394.
Next, let's calculate the total sales for each necklace: $10 (selling price).
To break even, the total expenses and total sales need to be equal.
Let n represent the number of necklaces:
Total expenses = $394 * n
Total sales = $10 * n
Setting the two equations equal to each other, we have: $394 * n = $10 * n.
Now, let's solve for n:
$394 * n = $10 * n
$394 = $10
n = 394 / 10
n = 39.4
Since we cannot sell a fraction of a necklace, Bret would need to make and sell 40 necklaces to break even.
The total expenses for 40 necklaces would be $394 * 40 = $15,760, and the total sales would be $10 * 40 = $400.
About 15% of the population of a large country is allergic to pollenallergic to pollen. if two people are randomly selected, what is the probability both are allergic to pollen? what is the probability at least one is allergic to pollenallergic to pollen?
Answer:
(a) 0.0225
(b) 0.225
Step-by-step explanation:
It is given that 15% of total population is allergic to pollenallergic to pollen.
Thus, Probability of an individual s/he has allergy is 0.15
Thus, The probability that two person is selected and both has allergy is 0.15 × 0.15 = 0.0225
And the Probability that at least one person is suffered from allergy from that two person = P(allergic and non-allergic) + P(non-allergic and allergic)
⇒ 0.15 × (1 - 0.15) + (1 - 0.15) × 0.15
⇒ 0.15 × 0.85 + 0.85 × 0.15 = 0.225

What is the range of the function y=2sin x
Answer:
Range: [-2, 2] {y | -2 ≤ y ≤ 2}
Step-by-step explanation:
The given function is y = 2sinx
We have to find the range of the given function.
Since at y-axis sine function has the variance between -1 to 1 so range of y = sinx is [-1, 1]
and if the amplitude of sine function is 2 then sine function will vary from -2 to 2 which implies that range of y = 2 sinx will be [-2, 2]
So range of y = 2sinx is [-2, 2]
The range of the function y=2sin x is mathematically given as
dy=(-2,2)
What is the range of the function y=2sin x?Question Parameter(s):
function y=2sin x
Generally, the equation for the wave is mathematically given as
[tex]y(x,t)=Asin(kx−wt+\phi)[/tex]
Therefore, Comparing both equations
y(x,t)=Asin(kx−wt+\phi)
y=2sin x
We have
A=2
In conclusion, The range of a function y=2sin x is simply defined as the probable outcomes, with x values as independent factors.
Hence, with sinx having min and max values at (-1,1)
The y value range will be
dy=(2(-1),2(1))
dy=(-2,2)

Find two positive numbers a and b (witha≤b) whose sum is 88 and whose product is maximized.
a + b = 88
ab = y
a = 88 - b
y = (88 - b)*b
y = -b^2 + 88b
Take the derivative and set equal to 0
y' = -2b + 88 = 0
2b = 88
b = 44
a=44
both numbers are 44
To find two positive numbers a and b whose sum is 88 and whose product is maximized, we can use the concept of quadratic equations. By taking the derivative of the product function and setting it equal to zero, we can find the maximum value. Plugging that value back into the product function will give us the maximum product.
Explanation:To find two positive numbers a and b whose sum is 88 and whose product is maximized, we need to use the concept of quadratic equations. Let's assume a as x and b as 88-x. The product of the two numbers can be expressed as the quadratic equation P(x) = x(88-x). To maximize the product, we need to find the maximum value of P(x). We can use calculus to find the maximum value by taking the derivative of P(x) and setting it equal to zero. Solving that equation will give us the value of x, and plugging it back into P(x) will give us the maximum product.
Let's go through the steps:
Write the quadratic equation: P(x) = x(88-x).Take the derivative of P(x) and set it equal to zero: P'(x) = 88-2x = 0.Solve for x: x = 44.Plug x back into P(x) to find the maximum product: P(44) = 44(88-44) = 1936.So, the two positive numbers a and b are 44 and 88-44, which is 44 as well. Their sum is 88 and their product is maximized at 1936.
The population of a town is decreasing at a rate of 1.1% each year. If there are 3,000 people in the town right now, how many people will be living in the town in 10 years? Round your answer to the nearest whole number.
total = 3000*(1-0.011)^10
1-0.011 = 0.989
total = 3000*(0.989)^10
0.989^10 = 0.895288314
3000* 0.895288314 = 2685.86
rounded to nearest whole number = 2686

You are getting a line-up ready for a school kickball game. you have 55 girls and 55 boys. the rules state each child must kick the same number of times and alternate girl-boy or boy-girl. how many ways can a line-up be made for one round of kicking
To solve this problem,
we must first imagine out that the sequence of the children is either
GBGBGB.... or BGBGBG....
So there are 2
possible sequence all in all. Now to solve for the total arrangements per
sequence, the
girls can be arranged in n! ways in their alloted spots, and so can the boys n!
in their alternate spots, therefore:
Total arrangements = 2 * n! * n!
If n = 55
Total arrangements = 2 * 55! * 55!
Total arrangements = (The answer is very big ~almost infinite)
If n = 5
Total arrangements = 2 * 5! * 5!
Total arrangements = 28,800
So I believe the correct given is 5 boys and 5 girls and there are a total of 28,800 arrangements.

If all racers are equal in skill, what is the probability that Ryan will be one of the top 3 racers?
Answer: The required probability is 25%.
Step-by-step explanation: Given that in an upcoming race, the top 3 finishers will be recognized with the same award and Ryan is one of 12 people entered in the race.
We are to find the probability that Ryan will be one of the top 3 racers, if all racers are equal in skills.
Let S denote the sample space of the experiment for selecting a racer and A denote the event of selecting the top 3 finishers.
Then, according to the given information, we have
n(S) = 12 and n(A) = 3.
So, the probability of event A is given by
[tex]P(A)=\dfrac{n(A)}{n(S)}=\dfrac{3}{12}=\dfrac{1}{4}\times100\%=25\%.[/tex]
Thus, the required probability is 25%.
