Note that where the cylindrical and the cuboidal containers shown below have the same height. the same amount of water was poured into each container. The water filled 1/2 of the cylindrical container and 1/3 of the cuboidal container. If the base area of the cylindrical container is 154 sq cm, the base area of the Cuboidal Container is 15.2
What is the justification for the above?Let the height of the cylinder and cuboidal container be h m
We know that the base of the cylinder container is given as: 154 sq cm.
Recall that the volume for a cylinder is = Base x Height
That means in this case:
The volume for the cylinder is = 154 x Height
Thus,
1/2 * 154h = 1/3h³
77h = 1/3h³; divide both side by h to get
77 = 1/3h²
Collecting like terms and make h subject of the formula, we have;
h² = 77 * 3
h² = 231
h = √231
h= 15.1986841536
h = 15.199 or [tex]\approx[/tex] 15.2

3. Mr. Black's pay increased by 15% when he got a raise, bringing his new salary to $184. What was Mr. Black's original pay?
Answer:
$160
Step-by-step explanation:
115% = $184
100% = X
let X be the original salary
(X is unknown)
115% = $184
100% = X
cross mutiply
115 x X = 100 x 184
115X = 18400
X = 18400 divided by 115
X = $160
therefore,Mr Black's original salary before increased by 15% was $160

Answer:
a) ∠VUW
b) VY
c) XYV
d) 180°
e) 65°
Step-by-step explanation:
Part A:A central angle is an angle that creates an arc in a circle, while also having its vertex as the center of the circle.
Here the center is U. So, the vertex of the angle must include U.
This means that there are multiple answers to part a.
The answers can be:
∠VUW
∠WUX
∠XUV
Part B:A minor arc is any arc that doesn't exceed 180°.
The possible answers for part b, using this definition are:
WV
VY
XY
Part C:The answer you inputted here is incorrect.
The order of the letters matter.
A tip for you to never mess these up is to trace the letters you've chosen with your finger and see if that image you make with your finger matches up with the shape you wanted to make.
An arc that makes a semicircle is an arc that connects the endpoints of the diameter. The diameter in this case is VX.
This means that your answer must start with V and end with X, or the other way around. (Meaning you could start with x and end with v, but always make sure you keep the endpoints of the diameter as the endpoints of the arc.)
The possible answers for this part are either:
VYX or VWX
Part D:This arc intercepts the diameter, which is a straight line and a central angle.
The angle of a diameter is 180°.
The arc of an intercepted central angle has the same measure of the central angle itself.
So, the measure of VWX is 180°.
Part E:If an arc intercepts a central angle, then the arc has the same measure as the central angle.
This rule works the other way around, too.
So, the central angle has the same measure as the minor arc that it intercepts.
Measure of arc VUW is 65°, so m∠VUW is also 65°.

Answer:
x = 22°
Step-by-step explanation:
Between two parallel lines, the opposite inside angles will be congruent. So, x is equal to angle V. The sum of the angles of any triangle will be 180°. Therefore, you can find the value of x by setting all the angles of the triangle SRV equal to 180°.
S = 5x + 4
R = 44
V = x
S + R + V = 180 <----- General equation
(5x + 4) + 44 + x = 180 <----- Insert values
5x + 48 + x = 180 <----- Add 4 and 44
6x + 48 = 180 <----- Add 5x and x
6x = 132 <----- Subtract 48 from both sides
x = 22 <----- Divide both sides by 6

The diameter of an electric cable is normally distributed, with a mean of 0.9 inch and a standard deviation of 0.02 inch. What is the probability that the diameter will exceed 0.92 inch? (You may need to use the standard normal distribution table. Round your answer to three decimal places.)
The probability that the diameter of the electric cable that is normally distributed will exceed 0.92 inch is 0.841
What is probability?Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events
How to determine the probability?The given parameters are:
Mean = 0.9
Standard deviation = 0.2
Calculate the z-score at x = 0.92 using
[tex]z = \frac{x - \mu}{\sigma}[/tex]
This gives
z = (0.92 - 0.9)/0.02
Evaluate the numerator; subtract 0.9 from 0.92
z = 0.02/0.02
Divide 0.02 by 0.02. This gives
z = 1
The probability is then represented as:
P(x > 0.92) = P(z > 1)
Next, we look up the value of the z table of probabilities
From the z table of probabilities, we have:
P(x > 0.92) = 0.841
Hence, the probability that the diameter of the electric cable that is normally distributed will exceed 0.92 inch is 0.841

How to determine the trigonometric ratiosFrom the figure, we have the values of the sides to be;
opposite side = 5Adjacent side = 4Let's use Pythagorean theorem to find the hypotenuse(x)
Hypotebuse square = opposite side square + adjacent side square
Substitute the values deduced from the figures given
x² = 5² + 4²
x² = 25 + 16
x² = 41
x = [tex]\sqrt{41}[/tex]
x = 6. 4
sin θ = opposite/hypotenuse
Substitute the values
sin θ = 5/ 6. 4
tan θ = opposite/ adjacent
Substitute the values
tan θ = 5/ 4
sec θ = hypotenuse/ adjacent
substitute the values
sec θ = 6. 4/ 4
Thus, the exact values of sec θ, tan θ and sin θ are 6.4/4, 5/4 and 5/ 6.4 respectively.

A stadium has 53,000 seats. Seats sell for $25 in Section A, $20 in Section B, and $15 in Section C. The number of seats in Section A
equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,131,000 from each sold-out event. How many seats
does each section hold?
The number section A, section B and section C seats sold are 26500, 14200 and 12300 respectively.
How to use equation to find the total number of seat in each section?The stadium has 53,000 seats.
Seats sell for $25 in Section A, $20 in Section B, and $15 in Section C.
The number of seats in Section A equals the total number of seats in Sections B and C.
Therefore,
a = b + c
a + b + c = 53000
b + c + b + c = 53000
2b + 2c = 53,000
25a + 20b + 15c = 1131000
25(b + c) + 20b + 15c = 1131000
25b + 25c + 20b + 15c = 1131000
45b + 40c = 1131000
Hence,
2b + 2c = 53000
45b + 40c = 1131000
40b + 40c = 1060000
45b + 40c = 1131000
-5b = - 71000
b = - 71000 / -5
b = 14,200
Therefore,
2(14,200) + 2c = 53000
2c = 53000 - 28400
2c = 24600
c = 24600 / 2
c = 12300
Hence,
a = b + c
a = 14200 + 12300
a = 26500

Which inequality is true when x = 4?
A. X+5<_3
B.x/2<3
c.9x>36
D.18<_-8
Answer:
[tex] \sf{b. \frac{x}{2} <3}[/tex]
step by step explanation:
We will try one by one.
A. x + 5 < 3
Step 1. Subtitution Value of x
= 4 + 5 < 3
Step 2. Add by 4 with 5
= 9 < 5
A is wrong because 9 is bigger then 5
B. x/2 < 3
= 4/2 < 3
= 2 < 3
is true because 2 is smaller than 3
C. 9x > 36
9(4) > 36
36 > 36
is wrong, should 36 = 36
D. 18 < 8
is wrong because 18 is bigger than 8
Please draw the number line and show me if possible:)

The formula for the squirrel population is P(t) = 400 e^0.5t and the doubling time of the population is 17. 68 years
Growth constant
The growth constant k can be defined as the frequency or also known as the number of times per unit time of growing by a factor
it is also called the logarithmic return, compounded return, or the force of interest.
Note that the general formula for growth rate is given as;
[tex]P(t) = P0 e^k^t[/tex]
Where,
Po = Initial value = 400 squirrels
r = Rate of growth
k = constant of proportionality = 0. 5 per year
t = time = 1 year
The function P(t) is given as;
P(t) = 400 e^0.5t
Note that the formula for doubling time is given as;
[tex]TD = t \frac{In 2}{In 1 + r/ 100}[/tex]
r = 4
t = 1
substitute into the formula
[tex]TD = 1 \frac{0. 693}{0. 0392}[/tex]
Doubling time = 1 × 17. 68
Doubling time = 17. 68 years
Thus, the formula for the squirrel population is P(t) = 400 e^0.5t and the doubling time of the population is 17. 68 years

The value of the limit of the function given when the value of x tends to zero is 0
What is a limit of a function?The limit of a function is a fundamental concept in calculus and analysis concerning the behavior of that function near a particular inputs.
Given the function limit below;
lim x→0 [1 − cos(2x) /x]
Substitute the value of x into the expression to have;
f(0) = 1-cos2(0)/0
f(0) = 1-1/0
f(0) = 0/0 (ind)
Apply the L'hospital rule to have:
lim x→0 [ − (-2sin2x)) /1]
Substitute the value of x into the result
f(0) = 2sin2(0)/1
f(0) = 2(0)
f(0) = 0
Hence the value of the limit of the function given when the value of x tends to zero is 0
