The volume of a water tank is 396 m^3. If it is 7.2 m long and 5.5 m wide. what is the depth of the tank ?
Answer :
Depth of the tank is of 10mStep-by-step explanation :
We have been provided with the volume of water tank , it's length and breadth. We are asked to calculate the depth of tank (height), so we all know that water tank is always is in the shape of cuboid.
We would be using the formula of calculating the volume of cuboid and substitute the values in it.
V = l × b × hHere,
l is length b is breadth h is heightWe have :
Volume (V) = 396m³length (l) = 7.2mbreadth (b) = 5.5m height (h) = ?Substituting the values :
>> 396 = 7.2 × 5.5 × h
>> 396 = (72 / 10) × (55 / 10) × h
>> 396 = 72 × 55 × h / 100
>> 396 = 3960 × h / 100
>> 396 × 100 = 3960 × h
>> 39600 = 3960h
>> h = 39600 / 3960
>> h = 3960 / 396
>> h = 10

What is the median of these ages?
Answer:
17
Step-by-step explanation:
The median of a data set can simply be thought of as the middle value/number.
You could list all values out:
16, 16, 16, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 18, 18, 18, 18, 18, 18, 18, 18, 19, 19, 19
and then find what the middle of 24 would be (There are an even number of values, so both numbers in places 12 and 13 are considered the median, meaning that we find the average of these two values to be our median)
the 12th value is 17, and the 13th value is 17, meaning that the median is 17.
-----------------------
You could also calculate what would be 12 "in" from the data set. The first 4 values are 16 (12 - 4 = 8 ; 8 values left to go until middle) And then take the remaining 8 places to find the 12th value (9 - 8 = 1), so you know that the 12th value is the 8th repetition of 17.
There is still one more value of 17, so that is also the 13th placed value.
In this method of finding the middle number, the median is still 17.
The median of these ages is 17.
What is the median?The median exists as the middle number in a sorted checklist of numbers and can be better descriptive of that data set than the average. The median exists sometimes utilized as objected to the mean when there exist outliers in the sequence that might skew the average of the values.
The median of a data set can only be considered as the middle value.
Let the values be 16, 16, 16, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 18, 18, 18, 18, 18, 18, 18, 18, 19, 19, 19
To find the middle of 24 would be (There exist an even number of values, so both numbers in places 12 and 13 exist considered the median) the 12th value stands at 17, and the 13th value stands at 17, indicating that the median exists at 17.
You have to calculate an estimate of 12 "in" from the data set. The first 4 values exist 16 (12 - 4 = 8; 8 values left to go until middle)
Consider the remaining 8 places to estimate the 12th value (9 - 8 = 1)
The 12th value exists in the 8th repetition of 17.
Therefore, the median of these ages is 17.

What is the equation of the function described?
The equation for the sinusoidal function described is given as follows:
[tex]y = 4\cos{\left(\frac{1}{2}x\right)} + 2[/tex]
What is a sinusoidal function?We want a function with a y-intercept at it's maximum value, hence we use the cosine equation, given by:
[tex]y = A\cos{\left(\frac{2\pi}{B}x\right)} + C[/tex]
In which:
2A is the amplitude, which is the difference between the largest and smallest value.B is the period.C is the vertical shift, considering that the standard cosine function has range between -A and A.The amplitude is of 8, hence 2A = 8 -> A = 4. This would represent a function between -4 and 4, but we want between -2 and 6, hence the vertical shift is of C = 2.
As for the period, we have that:
[tex]B = 4\pi[/tex]

If 48 people chose winter, then how many people were surveyed?
A.29
B.32
C.80
D.128
Answer:
C. 80Step-by-step explanation:
Let the number of people were surveyed is x.
We have 60% of x is 48 people.
Set this as equation and solve:
60% of x = 48x*60/100 = 480.6x = 48x = 48/0.6x = 80Correct choice is C.
Answer:
C. 80
Step-by-step explanation:
Given:
60% = 48 peopleLet x be the total number of people surveyed.
Set up a ratio of people to percentage and solve for x:
[tex]\implies \sf 48 : 60 = x : 100[/tex]
[tex]\implies \sf \dfrac{48}{60}=\dfrac{x}{100}[/tex]
[tex]\implies \sf x=100 \cdot \dfrac{48}{60}[/tex]
[tex]\implies \sf x=\dfrac{4800}{60}[/tex]
[tex]\implies \sf x=\dfrac{480}{6}[/tex]
[tex]\implies \sf x=80[/tex]
Therefore, the total number of people who were surveyed was 80.
A spinner has 4 equal-sized sectors. They are green, yellow, orange, and purple. If you spin the spinner 52 times, how many times do you expect it to land on purple?
If you spin the spinner 52 times, we expect the spinner to land on purple approximately 13 times in 52 spins.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is usually expressed as a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to occur.
Since there are 4 equal-sized sectors on the spinner, the probability of landing on purple on any given spin is 1/4.
To find the expected number of times the spinner will land on purple in 52 spins, we can multiply the probability of landing on purple by the total number of spins:
Expected number of times landing on purple = (Probability of landing on purple) x (Total number of spins)
Expected number of times landing on purple = (1/4) x (52)
Expected number of times landing on purple = 13
Therefore, we expect the spinner to land on purple approximately 13 times in 52 spins.

At a swimming pool the ratio of children to adults was 3 : 2
Out of 930 people, how many were adults?
Answer:
372
Step-by-step explanation:
We know that a ratio of 3 : 2 has 5 people, so figuring out how many times that ratio goes into our total number helps us find the value of the total number of adults.
930 / 5 = 186
This means that there are 186 groups of 3 children to 2 adults
So, in each of the 186 groups, there are 2 adults.
Therefore, we can multiply (186)(2)
to find the total number of adults: 372
The number of the children and adult will be 558 and 372.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
At a swimming pool, the ratio of children to adults was 3 : 2.
C / A = 3 / 2
Then solve the equation for C, then the equation will be
C = (3/2)A
The total number of the people is 930. Then the equation will be
C + A = 930
Substitute the value of C in the above equation. Then the equation will be
(3/2)A + A = 930
(5/2)A = 930
A = 930 x (2/5)
A = 372
The number of the adult will be 372.
Then the number of the children will be
C + 372 = 930
C = 930 – 372
C = 558
The number of the children will be 558.
Thus, the number of the children and adult will be 558 and 372.

Substitution methodElimination method.We will limit ourself to Substitution method.
3x – 2y = -4.................... 1.
4x + 2y = 25................... 2.
First lets manipulate eq.2 in terms of y.
4x + 2y = 25
2y = 25 - 4x
y = 25/2 - 2x .............. eq.3
Substitute eq.3 into eq.1
3x – 2(25/2 -2x) = -4
Solve for x.
Opening the brackets

Owen’s rectangular garden has a length of (x+3) feet and a width of (x−4) feet. If the area of the garden is 18 square feet, what are the dimensions of the garden?
Answer:
length: 9 units width: 2 units
Step-by-step explanation:
The formula to find the area of a rectangle is length*width (LW)
x+3 is the length and x-4 is the width; together they multiply up to 18
(x+3)(x-4) = 18
x^2 - 4x + 3x - 12 = 18 (multiply it out using FOIL)
x^2 - x - 12 = 18 (combine like terms on the left side)
x^2 - x -30 = 0 (subtract 18 from both sides so that the right side is 0)
Think what two numbers multiply up -30 and add up to -1 (5 and -6)
(x+5)(x-6) = 0 (factor it)
x+5 = 0 and x-6 = 0 (solve using zero-product property)
x = -5 and x = 6 (solve)
x = 6 (only this one works since you cannot have a negative side length)
(6+3)(6-4) = 18 ? (plug in to find side lengths and check)
9 * 2 = 18 (Correct!)
Answer:
length: 9 ft
width: 2 ft
Step-by-step explanation:
This can be worked using a quadratic equation, or it can be worked by considering factors of the area value.
__
difference in dimensionsThe difference in length between the long side (x+3) and the short side (x-4) is ...
(x +3) -(x -4) = 3+4 = 7 . . . . feet
area factorsThe area formula is ...
A = LW
The given area is 18 square feet, so we want to find numbers that multiply to give 18 and that differ by 7 in their values. Here are the integer factors of 18:
18 = 1×18 = 2×9 = 3×6
Of these factor pairs, the values 2 and 9 differ by 7.
The garden is 9 feet long and 2 feet wide.
_____
Additional comment
We can check to see if these numbers are consistent with the given expressions:
x+3 = 9 ⇒ x = 6
x -4 = 6 -4 = 2 . . . . the other dimension we found
__
If you solve this using a quadratic equation, you will find that dimensions -2 ft and -9 ft also pop out. That is x +3 = -2, or x = -5 is also a solution to the quadratic. Of course, that is an extraneous solution, which we avoid by considering only positive factors of 18.
The quadratic equation we're referring to is A=18 ⇒ (x+3)(x-4) = 18.

We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.
How to get the sum of the first 8 terms?
In an arithmetic sequence, the difference between any two consecutive terms is a constant.
Here we know that:
[tex]a_1 = 3/5\\a_8 = 1/4[/tex]
There are 7 times the common difference between these two values, so if d is the common difference:
[tex]a_1 + 7*d = a_8\\\\3/5 + 7*d = 1/4\\\\7*d = 1/4 - 3/5 = (5 - 12)/20 = -7/20\\\\d = -1/20[/tex]
Then the sum of the first 8 terms is given by:
[tex]3/5 + (3/5 - 1/20) + (3/5 - 2/20) + ... + (3/5 - 7/20)\\\\8*(3/5) - (1/20)*(1 + 2 + 3+ 4 + 5 + 6 + 7) = 3.4 = 34/10 = 17/5[/tex]
