The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best interpretation of v(3) = 27?
Answers
Answer:
Step-by-step explanation:
The volume of the cube depends on the length of its sides.
Volume can be represented by the function
V(s) = s³
Where s represents the length of one side.
Now V(3) = 27
or V(3) = 3³ will represent the volume of the cube with a side of length 3 unit.

Using rounding or compatible numbers, we estimate the product
[tex]5\times2 \frac{3}{5} [/tex]
to
[tex]5\times3[/tex]
Therefore, the estimate of the product [tex]5\times2 \frac{3}{5} [/tex], using rounding and compatible numbers is about 15.
Part 2
Using rounding or compatible numbers, we estimate the quotient
[tex]25\frac{7}{8}\div2 \frac{8}{9} [/tex]
to
[tex]27\div3[/tex]
Therefore, the estimate of the quotient [tex]25\frac{7}{8}\div2 \frac{8}{9} [/tex], using rounding and compatible numbers is about 9.
Part 3
Given that Mr. Garcia's class ate [tex]3\frac{2}{3}[/tex] pizzas, Mrs Rizzoli's class ate [tex]4\frac{1}{8}[/tex] pizzas, and Mrs. Tindal's class ate [tex]3\frac{1}{4}[/tex] pizzas.
Using benchmarks, we estimate the total number of pizzas eaten by all three classes as follows: [tex]3\frac{3}{4}[/tex], [tex]4[/tex] and [tex]3\frac{1}{4}[/tex]
Thus, the total number of pizzas eaten by all three classes is given by
[tex]3\frac{3}{4}+4+3\frac{1}{4}=11[/tex]
Therefore, the total number of pizzas eaten by all three classes is about 11.
To estimate the product or quotient, round numbers to the nearest whole or compatible number: 5 multiplied by 2 3/5 is about 15; 25 7/8 divided by 2 8/9 is about 9; and the total pizzas eaten by all classes is about 11.
Estimation with Rounding and Compatible Numbers
The estimation of products or quotients using rounding or compatible numbers involves adjusting values to simpler, more manageable numbers before performing the calculation. Here's how to estimate each of the provided examples:
For estimating the product of 5 by 2 3/5, you can round 2 3/5 to 3, which is a compatible number since 5 times 3 equals 15. Hence, the estimated product is about 15.To estimate the quotient of 25 7/8 divided by 2 8/9, round 25 7/8 to 26 (as 7/8 is close to a whole) and 2 8/9 to 3 (since 8/9 is close to 1), resulting in an estimated quotient of about 9 when you divide 26 by 3.For the total pizzas eaten by all three classes, use benchmarks: 3 2/3 rounds to 4, 4 1/8 rounds to 4, and 3 1/4 rounds to 3. Adding these gives 4+4+3 which equals 11. So, the total estimated number of pizzas is about 11.These estimations use the concept of rounding to the nearest whole number or to a fractions compatibility and demonstrate the importance of not over-representing the precision in your answer. Moreover, estimations are especially useful in mental math and when an approximate answer is sufficient.

A city ordinance in River City requires that there be a police officer for every 470 residents. If the population of River city is 410,300, what is the minimum number of police officers needed?
Answers
To meet the city ordinance's requirement, River City needs at least 874 police officers, determined by dividing the population of 410,300 by 470 and rounding up to the nearest whole number.
To determine the minimum number of police officers needed for the population of River City, we simply divide the city's population by the number of residents per officer as required by the ordinance. In this case, we divide 410,300 residents by the ordinance's requirement of one officer for every 470 residents.
Calculation: 410,300 residents / 470 residents per officer = approximately 873.19.
Since we cannot have a fraction of a police officer, we round up the number to the nearest whole number to ensure that we meet the minimum requirement. Therefore, River City needs at least 874 police officers.

Consider a civilization broadcasting a signal with a power of 2.0×104 watts. The Arecibo radio telescope, which is about 300 meters in diameter, could detect this signal if it is coming from as far away as 141 light-years. Suppose instead that the signal is being broadcast from the other side of the Milky Way Galaxy, about 70000 light-years away.
Answers
For light: Inverse Square Law
The signal is weaken by the inverse square of the
difference of distances this means that one over the square of the
difference.
Therefore, 70000LY / 141 LY =496.45 and that squared =246462.602 times less signal, or 1/246462.602.
2 For a circular telescope like the
Arecibo radio telescope that equals Pi times the radius squared. Sensitivity
of the telescope depends on its area.
The new telescope needs 246462.60 times that area to have
enough sensitivity
(150 x 150 x Pi) = 70 685 sq m area for the Arecibo telescope
and that times 246462.60

What is the diameter of a circle with that area?
1. Divide the area by Pi = 5.548156 x 10^9
2. Take the square root of the result to find the radius = 74485.94293

Is 81 in the sequence with the nth term 4n+1?
Explain
Answers
To justify that, it helps to think about ways we can represent numbers in terms of quotients and remainders. For example, if we take 10/3, we’ll obtain the quotient 3 with a remainder of 1, so another way of writing 10 would be 3(3)+1. If we replace that second three with any integer n, 3n+1 represents *every number* that leaves us with a remainder of 1 when we divide it by 3.
By the same logic, 4n+1 represents every number that leaves a remainder of 1 when we divide it by 4. 81 indeed meets this requirement, since can be written as 4(20)+1, so it would be a part of the sequence.

Jacob has 16 toy cars.3/8 of the cars are red and the rest are blue.how many cars are blue
Answers
Answer:
The number of blue toy cars that Jacob has is 10.
Solution:
Given:
Total number of toy cars = 16
Number of red cars = [tex]\frac{3}{8}[/tex] of the total number of cars = [tex]\frac{3}{8}\times16[/tex]
On dividing 8 and 16 we get 2 i.e. [tex]3\times2=6[/tex]
[tex]\therefore[/tex] Total red cars = 6
To find: the number of blue toy cars
Number of blue toy cars = Total number of toy cars - Number of red cars
[tex]\Rightarrow 16-6=10[/tex]
Hence, blue cars = 10

D) Triangle MNO is reflected across the y-axis and then rotated 180° clockwise to form triangle M"N"O".
Answers
Answer: A) Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle M"N"O".
Step-by-step explanation:
We know that we prefer rigid motions to create congruent images.
There are four kinds of rigid motions:
1) translation 2) reflection 3) rotation 4) glide reflection.
But a dilation is a transformation that creates an image having similar shape as the original, but with a different size.
So it does not create congruent images.
Hence transformations will produce similar, but not congruent, figures is :
Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle M"N"O".
Molly bought a pair of gloves and a skirt. The gloves cost £4. She sold teh gloves and the skirt for a total of £48. She made 100% profit on the cost of the gloves. 20% profit on the total cost. Work out the percentage profit on the cost of the skirt
Answers
Profit on the total cost = 20% = 0.20
=> Total cost + 0.20 total cost = Sale value
=> 1.20 total cost = 48
=> total cost = 48 / 1.20
=> total cost = 40
B) Cost of the gloves = 4
=> Cost of the skirt = total cost - cost of the gloves
=> Cost of the skirt = 40 - 4 = 36
C) Price of the skirt = total value - price of the gloves
Total value = 48
Price of the gloves = cost of the gloves + margin
margin of the gloves = 100% on the cost = cost
Price of the gloves = cost of the gloves * 2
Price of the gloves = 4 * 2 = 8
=> Price of the skirt = 48 - 8 = 40
D) Profit on the skirt = price of the skirt / cost of the skirt = 40 / 36 = 1.1111
Profit % = 11,11 %
The profit-maximizing quantity for Doggies Paradise Inc. is determined by comparing marginal revenue and marginal cost for each output level and is found to be at five units, which results in a profit of $40.
Explanation:Profit Maximization CalculationTo calculate the profit-maximizing quantity for Doggies Paradise Inc., we construct a table showing total revenue, marginal revenue, total cost, and marginal cost for each output level from one to five units. Given the price of $72 per dog coat, the fixed costs of $100, and the various total variable costs for each output level, we can determine the profit-maximizing quantity by comparing marginal revenue and marginal cost.
Calculate total revenue by multiplying the number of units by the price ($72).Calculate total cost by adding fixed costs ($100) to the total variable costs for each output level.Determine marginal revenue and marginal cost for each additional unit produced.Identify the output level where marginal revenue equals marginal cost; this is the profit-maximizing quantity.Subtract total cost from total revenue to find profits at this output level.If Doggies Paradise Inc. produces and sells five units, they will achieve a profit of $40, as total revenue will be higher than total costs, indicating that the fifth unit is adding to the profits.
