Answer:
[tex]a = 10[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Velocity\ (u) = 20m/s[/tex]
[tex]Final\ Velocity\ (v) = 60m/s[/tex]
[tex]Time = 4s[/tex]
Required
Determine the acceleration
This question will be answered using the first equation of motion.
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]60 = 20 + 4 * a[/tex]
[tex]60 = 20 + 4 a[/tex]
Subtract 20 from both sides
[tex]60 - 20= 20 -20 + 4 a[/tex]
[tex]40= 4 a[/tex]
Divide both sides by 4
[tex]10 = a[/tex]
[tex]a = 10[/tex]
Hence, the acceleration is 10m/s/s

if a person is randomly selected from the US population, the odds the person lives in California are 1 to 8.
What is the probability of two decimal places of a randomly chosen person being from California?
What are the odds of a randomly chosen person not being from California?
Answer:
The probability of a randomly chosen person being from California is 0.111.
The probability of a randomly chosen person not being from California is 0.889.
Step-by-step explanation:
The odds of a person, selected from the US population, living in California is 1 to 8.
That is:
[tex]\text{Odds}(\frac{\text{Lives in California}}{\text{Does not Lives in California}})=\frac{1}{8}[/tex]
Compute the probability of a randomly chosen person being from California as follows:
[tex]P(\text{Lives in California})=\frac{\text{Odds}(\text{Lives in California})}{\text{Odds}(\text{Lives in California})+\text{Odds}(\text{Does not Lives in California})}[/tex]
[tex]=\frac{1}{1+8}\\\\=\frac{1}{9}\\\\=0.111[/tex]
The probability of a randomly chosen person being from California is 0.111.
Compute the probability of a randomly chosen person not being from California as follows:
[tex]P(\text{Love in California})=1-P(\text{Does not Love in California})[/tex]
[tex]=1-0.111\\\\=0.889[/tex]
Thus, the probability of a randomly chosen person not being from California is 0.889.

Which car has the best gas miles Car A 150 miles on 12 gallons or Car B 80 miles on 6.5 gallons
Answer:
kdtgufkgcvkmj
Step-by-step explanation:
Answer:
Car A
Step-by-step explanation:
We need to find the miles per gallon for both cars
So we divide the miles by the gallon
Car A: 150 ÷ 12 = 12.5 mpg
Car B: 80 ÷ 6.5 = ~12.3 mpg
The answer is Car A

cloud is a vegetable grower, has 8 4/15 plots of pechay, 5 1/3 plots of eggplants and 5 2/5 of okra . how many plots of vetable do cloud has?
Answer:
The total plots of vegetable cloud will have: 19
Step-by-step explanation:
As the cloud has:
[tex]8\frac{4}{15}[/tex] plots of pechay[tex]5\frac{1}{3}[/tex] plots of eggplants[tex]5\frac{2}{5}[/tex] plots of okaraSo, the total plots of vegetable cloud will have:
[tex]8\frac{4}{15}+5\frac{1}{3}+5\frac{2}{5}[/tex]
[tex]=\frac{124}{15}+\frac{16}{3}+\frac{27}{5}[/tex]
[tex]=\frac{124}{15}+\frac{80}{15}+\frac{81}{15}[/tex]
[tex]=\frac{124+80+81}{15}[/tex]
[tex]=19[/tex]
Therefore, the total plots of vegetable cloud will have: 19

please help calculus question urgent
Answer:
C
Step-by-step explanation:
We are given that:
[tex]\displaystyle k(x)=\frac{f(x)}{g(x)}[/tex]
And we want to find k'(3).
So, let's find k'(x). Take the derivative of both sides. This will require the Quotient Rule. Hence:
[tex]\displaystyle k^\prime(x)=\frac{f^\prime(x)g(x)-f(x)g^\prime(x)}{(g(x))^2}[/tex]
We want to find k’(3). Substitute:
[tex]\displaystyle k^\prime(3)=\frac{f^\prime(3)g(3)-f(3)g^\prime(3)}{(g(3))^2}[/tex]
Using the table, make the appropriate substitutions:
[tex]\displaystyle k^\prime(3)=\frac{5(2)-(-1)(-2)}{(2)^2}[/tex]
Evaluate:
[tex]\displaystyle k^\prime(3)=\frac{10-2}{4}=\frac{8}{4}=2[/tex]
Therefore, our answer is C.

How many exact tenths are in 21.34. Why is it not 3?
Answer:
213.4 tenths

2 Dylan is part of a volunteer crew constructing houses for low-income families. Dylan is experienced at installing tile floors. He is training a new volunteer, George, to complete tiling projects. A new job involves placing 100 tiles. Dylan knows from experience that it would take him 2 hours to complete the job if he were working alone. Dylan estimates that it would take George 4 hours to complete the job if George were working alone. If Dylan and George work together, how long will it take to complete the job?
Answer:
For the tiling Job; it takes the following for installing 100 tiles:
Dylan =2 hours
George = 4 hours
if they work together for the job, for 1 hour,
it would be the following no of tiles to be fixed:
Dylan + George = total tiles
100/2 + 100/4 = 50 + 25 = 75 tiles
If it takes George 1hr to fix 50 tiles,
For 30 minutes, Dylan will fix 25 tiles
Therefore Total tiles fixed = Dylan(1hr work) + George(1hr work) + Dylan (30mins work)
= 50 tiles + 25 tiles + 25 tiles = 100 tiles
Therefore, it will take approximately 1 hour for them to install 75 tiles in the low-income house for the families or
1.30 hours (1 hr, 30 minutes) to fix 100 tiles for the same low income families.

Find the number.
the sum of the reversed number and the original number is 154. Find the original number, if the ones digit in it is 2 less than the tens digit.
Answer:
86
Step-by-step explanation:
Let the number be 10x + y. So, the reversed number is 10y + x.
The sum is 154.
So, (10x + y) + (10y + x) = 154
⇒ 11x + 11y = 154
⇒ x + y = 14 ..... (1)
Again, given that ones digit in the original number is 2 less than the tens digit.
So, y = x - 2 ...... (2)
Now, solving (1) and (2) we get,
x + x -2 = 14
⇒ 2x = 16
⇒ x = 8
So, from equation (2), y = x - 2 = 8 - 2 = 6
Therefore, the original number is 10x + y = 10 × 8 + 6 = 86 (Answer)
