2: Take 3:16 and add until 3:34
The part of an hour 3/10
What is time elapsed?Elapsed time is the time taken by an event to occur between the start of the time and the end of the time. In simple words, we can say that the amount of time that has passed between the beginning and the end of an event is called the elapsed time. We can determine this time by subtracting the end time and the start time. The formula to calculate the elapsed time is simply to subtract the hours and minutes separately. It gives the duration of an event.
Elapsed time means the time that has elapsed between the start of the time and the end of the time.
For example, if a man starts traveling at 10:30 AM and ends the journey at 12:15 PM, the time elapsed is the duration of his journey, that is, the time between 12:15 PM and 10:30 AM. Elapsed time is an important concept as it helps us to learn to read the time on a clock and measure the time taken for an event to occur.
Formula:
Elapsed Time = End Time - Start Time
As, 3:16 p.m. shows 44 minutes before 4:00 p.m.
and, 3:34 p.m. shows 26 minutes before 3: 34 p.m.
As, there is difference of
=44-26
=18 minutes
Hence, the part of an hour = 18/60= 3/10

Which of the following relation is correct
Answer:
Both the equation and its inverse are functions.
Step-by-step explanation:
In order to solve this problem lets first find the inverse of this function. This is done below:
[tex]y = x^2 + 8\\[/tex]
We first swap x and y.
[tex]x = y^2 + 8[/tex]
We now isolate y.
[tex]y^2 = x - 8\\y = \sqrt{x - 8}\\f^{-1}(x) = \sqrt{x - 8}[/tex]
Functions are relations between two groups of numbers, in such a way that one number on the input group must generate a singular answer from the output group. This holds true for both f(x) and its inverse, therefore both are functions.

Find the value of x in the triangle shown below.
Answer:
x=48
Step-by-step explanation:
The other angle is 66° because it's an isosceles triangle
so
180=66+66+x
180=132+x
x=48
Answer:
48 degrees
Step-by-step explanation:
Since the triangle is iscoceles because it has two sides with a length of 7, two angles will be 66 degrees and the missing angle will be the sum of total angles in a triangle minus the other two 66 degree angles. 180 - 66 - 66 = 48

A right-angled triangle has shorter side lengths exactly c^2-b^2 and 2bc units respectively, where b and c are positive real numbers such that cc is greater than b. Find an exact expression for the length of the hypotenuse (in appropriate units).
Answer: hypotenuse = [tex]c^{2} + b^{2}[/tex]
Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side ([tex]s_{1},s_{2}[/tex]) of the right triangle, .i.e.:
[tex]h^{2} = s_{1}^{2} + s_{2}^{2}[/tex]
In this question:
[tex]s_{1}[/tex] = [tex]c^{2}-b^{2}[/tex]
[tex]s_{2} =[/tex] 2bc
Substituing and taking square root to find hypotenuse:
[tex]h=\sqrt{(c^{2}-b^{2})^{2}+(2bc)^{2}}[/tex]
Calculating:
[tex]h=\sqrt{c^{4}+b^{4}-2b^{2}c^{2}+(4b^{2}c^{2})}[/tex]
[tex]h=\sqrt{c^{4}+b^{4}+2b^{2}c^{2}}[/tex]
[tex]c^{4}+b^{4}+2b^{2}c^{2}[/tex] = [tex](c^{2}+b^{2})^{2}[/tex], then:
[tex]h=\sqrt{(c^{2}+b^{2})^{2}}[/tex]
[tex]h=(c^{2}+b^{2})[/tex]
Hypotenuse for the right-angled triangle is [tex]h=(c^{2}+b^{2})[/tex] units
The expression for the length of the hypotenuse is [tex]c^2+ b^2 \ units[/tex].
Given that,
A right-angled triangle has shorter side lengths exactly [tex]c^{2} - b^{2}[/tex] and 2bc units respectively,
Where b and c are positive real numbers such that c is greater than b.
We have to determine,
An exact expression for the length of the hypotenuse?
According to the question,
The Pythagoras theorem states that the sum of the hypotenuse in the right-angled triangle is equal to the sum of the square of the other two sides.
A right-angled triangle has shorter side lengths exactly [tex]c^{2} - b^{2}[/tex] and 2bc units respectively,
Where b and c are positive real numbers such that c is greater than b.
Therefore,
The expression for the length of the hypotenuse is,
[tex]\rm (Hypotenuse)^2 = (c^2-b^2)^2+ (2bc)^2\\\\(Hypotenuse)^2 = c^4+ b^4 - 2c^2b^2 + 4c^2b^2\\\\(Hypotenuse)^2 = c^4+ b^4 +2c^2b^2 \\\\Hypotenuse = \sqrt{c^4+ b^4 +2c^2b^2}\\\\\ Hypotenuse = \sqrt{(c^2+ b^2)^2}\\\\ Hypotenuse = c^2+b^2 \ units[/tex]
Hence, The required expression for the length of the hypotenuse is [tex]c^2+ b^2 \ units[/tex].

Formula for volume of a cylinder is πr² · h
1. Find the volume of the pool
π(3.5²) · 1.9 = 73.1 m³
2. Divide by the amount of water pumped out per hour (17 m³)
73.1 ÷ 17 = 4.3
It would take 5 hours to completely empty the pool but 4.3 rounded to the nearest whole hour is 4 hours.
Answer:
The hours does it take to empty the pool is 4.299
Step-by-step explanation:
In order to calculate how many hours does it take to empty the pool, we would have to make the following calculation:
hours does it take to empty the pool=Volume of cylinder/rate water is pumped out of the pool
rate water is pumped out of the pool=17m∧3
Volume of cylinder=pi*r∧2*l
According to the given data:
r=3.5
l=1.9
Therefore, Volume of cylinder=3.14*3.5∧2*1.9
Volume of cylinder=73.0835 m∧3
hours does it take to empty the pool=73.0835/17
hours does it take to empty the pool=4.299
The hours does it take to empty the pool is 4.299

V2=u2+2as v 2 = u 2 + 2 a s Where v v is the final velocity (in m/s), u u is the initial velocity (in m/s), a a is the acceleration (in m/s²) and s s is the distance (in meters). Find v v when u u is 9 m/s, a a is 7 m/s², and s s is 28 meters.
Answer:
Final velocity, v = 21.75 m/s
Step-by-step explanation:
Given that the relation between final velocity, initial velocity, acceleration and distance traveled is expressed as:
[tex]v^2=u^2+2as[/tex]
Also, given that:
Initial velocity, u = 9 m/s
Acceleration, a = 7 m/[tex]s^2[/tex]
Distance, s = 28 m
To find:
Final velocity, v = ?
Solution:
The given relation between v, u, a and s is:
[tex]v^2=u^2+2as[/tex]
We have the values of initial velocity, acceleration and distance traveled in the question statement. We just need to put all these values to find the value of final velocity.
Let us put all the values in the given equation and try to find final velocity, v:
[tex]v^2=9^2+2\times 7 \times 28\\\Rightarrow v^2=81+14 \times 28\\\Rightarrow v^2=81+392\\\Rightarrow v^2=473\\\Rightarrow v=\sqrt{473}\\\Rightarrow v=21.75\ m/s[/tex]
So, the answer is:
final velocity, v = 21.75 m/s
Martin will earn $25 per hour at a new job. During training, he will earn $20 per hour. What percent of Martin's regular hourly rate will he earn during training?
Answer:
He will earn 80% during training
Step-by-step explanation:
Lets take $25 as 100%
And take $20 as x
Using equivalent ratios, the equation would look like: $25:100% = $20:x
Next, turn them into fractions: $25 = $20
100% x
Cross multiply to get:
(25)x = $20×100%
The next step:
25x = $20×100%
25 25
25 and 25 will cancel each other out leaving x, and 25 will divide 100% which will give you 4
Leaving it as:
x= 20×4%
x= 80%
The logistic growth function f(t)equals440 Over 1 plus 13.7 e Superscript negative 0.28 t EndFraction describes the population of a species of butterflies t months after they are introduced to a non-threatening habitat. How many butterflies are expected in the habitat after 20 months? Round to nearest whole number.
Answer:
8685 butterflies
Step-by-step explanation:
Given the logistics growth function expressed as f(t)equals440 Over 1 plus 13.7 e Superscript negative 0.28 t which describes the population of a species of butterflies t months after they are introduced to a non threatening habitat, to know the number of butterflies expected butterflies are expected in the habitat after 20 months, we will substitute t = 20 into the function.
f(20) = 440/1+13.7exp-(0.28×20)
f(20) = 440/1+13.7exp-(5.60)
f(20) = 440/1+(13.7× 0.003698)
f(20) = 440/1+0.05066
f(20) = 440/1.05066
f(20) = 8684.9
This means there will be approximately 8685 butterflies in the habitat after 20months.

Answer:
La altura de la pirámide es de 8.14 unidades.
Step-by-step explanation:
Hay una pirámide cuadrangular regular cuyas caras laterales forman un ángulo que mide 53º con la base y el área de la superficie lateral es 60. ¿Qué altura tiene?
Dado que el área de superficie lateral = 60
Tenemos
Área del triángulo equilátero = (√3 / 4) × a²
(√3 / 4) × a² = 60
a² = 60 / (√3 / 4) = 80 · √3
a = √ (80 · √3) = 11.77 unidades
La altura inclinada = Altura de la superficie inclinada = a × sin (60) = 11.77 × sin (60)
La altura inclinada = 11.77 × sin (60) = 10.194 unidades
La altura de la pirámide = Altura inclinada × sin (ángulo de caras laterales con la base)
La altura de la pirámide = 10.194 × sin (53) = 8.14 unidades.
La altura de la pirámide = 8.14 unidades.

Given that Arccos (√3/2)=β, what are all the angle measurements for right triangle ABC?
Answer:
30°, 60° and 90°
Step-by-step explanation:
Given the expression Arccos (√3/2)=β, we can use the expression to calculate one of the acute angles in a right angled triangle.
Note that a right angled triangle is made up of two acute angles and a right angled (90°)
Let's get one of the acute angles first
If Arccos (√3/2)=β
β = cos^-1 √3/2
β = 30°
This shows that one of the acute angles is 30°
To get the third angle, we know that sum of angles in a triangle is 180° and since we already know two of the angles, i.e 90° and 30°, we can get the third angle.
90+30+x = 180
120+x = 180
x = 180-120
x = 60°
All the angle measurement for the right angled triangle are 30°, 60° and 90°
after allowing 20%discount on the m.p of a mobile,15% vat was levied and sold it.If the differences between selling price with vat and selling price after discount is rs.1800,find the marked price of the mobile
Answer:
Market price = Rs. 15,000
Step-by-step explanation:
Let Market price = x
discount = 20% of x
= 0.20 *x = 0.2x
Selling price after discount = x - 0.2x = 0.8x
Value added tax = 15% of 0.8x
= 0.15 * 0.8x
= 0.12x
Selling price with VAT = 0.8x + 0.12x = 0.92x
Differences between SP with vat and SP after discount = rs.1800
0.92x - 0.8x = 1800
0.12 x = 1800
x = 1800/0.12
x = Rs. 15,000

Answer: it’s d!
Step-by-step explanation:
Determine which one of the following statements is true.
A. Linear growth will always exceed exponential growth.
B. Linear growth will always exceed quadratic growth.
C. Quadratic growth will always exceed exponential growth.
D. Exponential growth will always exceed linear growth.
Answer:
D. Exponential growth will always exceed linear growth.
Step-by-step explanation:
An "exponential growth function" would always exceed the "linear growth function" in the end because the "x-values" tends to get larger in continuation, so the change rate associated with the "exponential function" also increases in continuation whereas the "linear functions' change rate is considered as constant.
In the question above, option D is correct.
What is the solution to this equation? 8 - 5(x - 3) = 18
Answer:
x = 1
Step-by-step explanation:
Given
8 - 5(x - 3) = 18 ( subtract 8 from both sides )
- 5(x - 3) = 10 ( divide both sides by - 5 )
x - 3 = - 2 ( add 3 to both sides )
x = 1
