Answer:
The median is 19.45
Step-by-step explanation:
Organize the numbers from least to greatest
16.3, 17.8, 17.8, 18.0, 18.7, 19.3, 19.6, 20.1, 20.5, 21.9, 25.2, 25.4
Find the middle of the set of numbers
19.3 and 19.6
Add 9.3 and 19.6
19.3 + 19.6=
38.9
Divide by 2
38.9/2
Which is 19.45

Show work for both questions.
Pleaseee don’t answer if you don’t know, I need this really soon.
Step-by-step explanation:
a)
[tex]\sin^{2}x + \cos^{2}x = 1[/tex]
Dividing both sides by sin^2x, we get
[tex]1 + \frac{\cos^{2}x }{ \sin^{2}x} = \frac{1}{\sin^{2}x } [/tex]
The 2nd term on the LHS is simply cot^2x and the RHS is simply csc^2x
[tex]1 + \cot^{2}x = \csc^{2}x[/tex]
b)
[tex]2 \sin x = 1[/tex]
[tex] \sin x = \frac{1}{2} [/tex]
[tex]x = \sin^{ - 1} (\frac{1}{2}) = \frac{\pi}{6} [/tex]
You can also graph it to arrive at the solution.

You have started keeping track of your spending habits. You have noticed that after 12 days you have
$1281 left in your account. You check again after 17 days have passed and your account is now at $861.
How many days will it take before you run out of money (assume you are spending money at a constant
rate)? Marks will be awarded only for the use of equations where t is the time elapsed in days and m is
the money left in your account in dollars.
Answer:
Time taken to elapse the remaining $861 = 10.25 days
Step-by-step explanation:
Assuming that I am spending at a rate of -x dollars per day
Let initial amount be A
The rate of expenditure = 1281-861/5 = 84 dollars per day
Time taken to elapse the remaining $861 = $861/$84 per day
= 10.25 days

Answer:
Step-by-step explanation:
Let older brother age be x and the age difference between the brothers be y
Younger brother's current age = x - y
When older brother's age was at x - y, younger brother's age was x - 2y = 2
When young brother's age will be at x, older brother's age will be x + y = 20
Subtracting the first equation from the second: 3y = 18
y = 6
x = 14
So the older brother is 14 and the younger brother is 8.
Sum of three son's ages now = 15 + 11 + 7 = 33
Daddy's age now = 45
Age difference = 12
Each year, daddy's age goes up by 1 while the sum of three son's ages goes up by 3.
Dividing the age difference by the difference in age gain, 12 / (3 -1) = 12 / 2
= 6
So in 6 years when daddy is 51 and the sum of sons at 21, 17 and 13 will be equal.
Answer:
Step-by-step explanation:
older bro age is x
younger bro age is y
age diff = x - y
it was (x-y) years ago when older bro was at age y
younger bro age then was y - (x - y) =2
2y - x = 2
younger bro will be at age x in (x-y) years
older bro age then will be x + (x-y) = 20
2x - y = 20
4x - 2y = 40
adding 2y - x = 2
3x = 42
x = 14
y = 2*14 - 20 = 8
daddy' age, 45 is 12 over the sum of sons (15, 11 and 7)
in 1 yr, dad age +1 n sum of sons +3 = difference of 2
so in 12/2 = 6 yrs they will be the same

The answer is A.
Y=64x²
X=64y²
X/64=y2

Answers: 49, 1, 49
Those values go in the blanks from left to right
=====================================================
Explanation:
The rule we use is x^(-k) = 1/(x^k)
That means if we're evaluating something like 7^(-1), then it's the same as 1/(7^1) = 1/7 which explains how x = -1 leads to y = 1/7.
Similarly, 7^(-2) = 1/(7^2) = 1/49 is the y value when x = -2. So you'll type 49 into the first box to fill in that missing denominator.
Raising any nonzero value to the zeroth power leads to 1. That rule is x^0 = 1 where x can be anything you want but it can't be zero. Therefore 7^0 = 1 goes in the second box.
Lastly, 7^2 = 7*7 = 49 will go in the third box.

Barry wants to make a drawling this is 1/2 the size of the original. If a tree in the original drawling is 11 inches tall and 7 inches wide, what will be the length and width of the tree in Barry's drawling?
Answer: 5.5 inches, 3.5 inches
Step-by-step explanation:
Given
Barry wants to make a drawing i.e. half the size of original
The length and width of the original drawing are 11 inches and 7 inches respectively.
So, the intended drawing is obtained by multiplying the original dimensions by [tex]\frac{1}{2}[/tex]
The length of barry's drawing is
[tex]\Rightarrow 11\times \frac{1}{2}\\\\\Rightarrow 5.5\ \text{inches}[/tex]
The breadth of barry's drawing
[tex]\Rightarrow 7\times \frac{1}{2}\\\\\Rightarrow 3.5\ \text{inches}[/tex]

A car has a value of £15000 at the start of the
year, at the end of the year the car is worth £14000.
What is the percentage decrease ?
Given :-
Value of car in start years Sv= $ 15,000Value of car in last years Ev = $ 14,000Find :-
% decrease .ExplanationUsing Formula
[tex]\boxed{\tt{\red{\:(Decrease)\:=\:(Sv\:-\:Ev)}}}[/tex]
==> Decrease value = 15000 - 14,000
==> Decrease Value = $1000
Now, Calculate % decrease .
★ % decrease = decrease × 100/Sv
==> % Decrease = 1000 × 100/15,000
==> % Decrease = 100/15
==> % Decrease = 6.67 % [ Ans]will give brainiest!!
Find the volume of the cone.
9 cm
r = 6 cm
V = [?] cm3
Round to the nearest tenth.
Volume of a cone is equal to pi * r^2 * h/3.
In this case:
pi * 6^2 * 9/3
pi * 36 * 3
108pi
Answer: 339.3
Answer: 339.292006588 or V ≈ 339.29
Step-by-step explanation: Here is the formula that you need...
V = π [tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex]
1. Multiply π (pi or approximately 3.14) by [tex]6^{2}[/tex] (36).
2. Multiply your answer from the last step which is 113.097335529 by [tex]\frac{9}{3}[/tex] or 3.
3. Final Answer should be 339.29 for the nearest tenth.
V = π [tex]6^{2}[/tex] [tex]\frac{9}{3}[/tex] which gives you...
V = 339.29

Can yall get me the volume calculations for the 3 shapes? Thank you! | Geometry
Figure 1
Name = Coneh = 4 unitsd = 8Since the diameter is 8, this cuts in half to the radius of r = 4. Plug the given values into the cone volume formula below
V = (1/3)*pi*r^2*h
V = (1/3)*pi*(4)^2*4
V = (64/3)pi ..... exact volume in terms of pi
V = (64/3)*3.14
V = 66.98667 .... approximate volume when using pi = 3.14
========================================================
Figure 2
Name = cylinderh = 4d = 8 which cuts in half to r = 4V = volume of cylinder
V = pi*r^2*h
V = pi*4^2*4
V = 64pi ..... exact volume
V = 64*3.14
V = 200.96 .... approximate volume when using pi = 3.14
========================================================
Figure 3
Name = rectangular prismb = 32h* = 12h = 4b and h* are dimensions along the bottom face, aka floor
h is the height or vertical dimension of the 3D room
V = volume of rectangular prism = volume of 3D room
V = length*width*height
V = (b)(h*)(h)
V = (32)(12)(4)
V = 1536 is the exact volume
There is no approximate volume for this figure because the result above is an integer.
========================================================
Combining the figures
Adding up the volumes for figures 1 through 3 gets us
(64/3)pi + 64pi + 1536 = (256/3)pi + 1536
The exact total volume in terms of pi is (256/3)pi + 1536
If we used pi = 3.14, then it leads to
(256/3)pi + 1536 = (256/3)*3.14 + 1536 = 1803.94667
The approximate total volume of all three figures combined is roughly 1803.94667 cubic units
A truck is bought at the price of $60,000. The value decreases at the rate of .25 every year (t). The exponential expression 60,000(0.75)t describes this situation. Find the value of the truck at 2 years.
Answer:
$33750
Step-by-step explanation:
Replace t with 2. The correct formula is
[tex]60000(.75)^t[/tex] (t is an exponent)
With t = 2, the value of the truck is
[tex]60000(.75)^2=33750[/tex]
