If Misty has been traveling for 9 hours, how many miles of the trip does she have remaining?
Answer:
Distance remaining (out of total 81 miles) after travelling 9 hours at speed 3 miles per hour = 54 miles
Step-by-step explanation:
Lets suppose -
Time = 9 hours
Total Distance = 81 miles
Speed = 3 miles per hour
Distance = Speed x TimeDistance covered in 9 hours = 3 x 9 = 27 miles
Distance remaining = Total distance - distance covered= 81 - 27 = 54 miles
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.

Find the cosine of R.
Write your answer in simplified, rationalized form. Do not round.
cos(R) =
Answer:
[tex] cos(R) = \frac{\sqrt{15}}{5} [/tex]
Step-by-step explanation:
To find the cosine of <R, apply the following trigonometric ratio formula:
[tex] cos(R) = \frac{adjacent}{hypotenuse} [/tex]
Adjacent = 3
Hypotenuse = √15
Plug in the values into the formula
[tex] cos(R) = \frac{3}{\sqrt{15}} [/tex]
Multiply the numerator and denominator by √15 to rationalize.
[tex] cos(R) = \frac{3 \times \sqrt{15}}{\sqrt{15} \times \sqrt{15}} [/tex]
[tex] cos(R) = \frac{3\sqrt{15}}{(\sqrt{15})^2} [/tex]
[tex] cos(R) = \frac{3\sqrt{15}}{15} [/tex]
[tex] cos(R) = \frac{\sqrt{15}}{5} [/tex]

Let t as y² + 5y .
[tex] {y}^{2} + 5y = t[/tex]
Rewrite the equation :
[tex]t - \frac{36}{t} = 0 \\ [/tex]
Multiply sides by t
[tex]t \times (t - \frac{36}{t} ) = t \times 0 \\ [/tex]
[tex] {t}^{2} - 36 = 0[/tex]
Add sides 36
[tex] {t}^{2} - 36 + 36 = 0 + 36[/tex]
[tex] {t}^{2} = 36[/tex]
[tex]t = ± \: 6[/tex]
_________________________________
So :
[tex] {y}^{2} + 5y = 6[/tex]
Subtract sides 6
[tex] {y}^{2} + 5y - 6 = 6 - 6[/tex]
[tex] {y}^{2} + 5y - 6 = 0[/tex]
[tex](y + 6)(y - 1) = 0[/tex]
[tex]y = - 6 \: \: or \: \: y = 1[/tex]
##############################
[tex] {y}^{2} +5y = - 6[/tex]

In a basketball tournament, Team A scored 5 fewer than twice as many points as Team B. Team C scored 80 more points than Team B. The combined score for all three teams was 983 points. Write an equation to represent this scenario using the variable b to represent Team B’s total points.
Translate the scenario.
Team A =
Team B =
Team C =
The equation representing this scenario is
.
Answer:
Team A = 449
Team B = 227
Team C = 307
Equation is
(2b-5) + b + (b+80) = 983
simplyfying
4b+75 = 983
Step-by-step explanation:
Take 4b+75 = 983
b = (983 - 75)/4 = 227
now
Team A = 5 less than twice as many as team B = 2b - 5 = 2 *227-5 = 454-5= = 449
Team B = b = 227
Team C = 80 more than team B = b+80 = 227+80 = 307
or you can just subtract 983 - (Team A +Team B)
Answer:
Team A = 449
Team B = 227
Team C = 307
Equation is
(2b-5) + b + (b+80) = 983
simplyfying
4b+75 = 983

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.

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.
Given the equation 3x + 4y = 10, select a second equation that would create a system with no solutions.
3x + 4y = -10
3x - 4y = 10
3x + 4y = 10
3.x - 4y = -10
Answer:
3x + 4y = -10
Step-by-step explanation:
Here, we want to select which of the options will give a system of two equations coupled with the first such that we have no solutions
Since we already have 3x + 4y = 10
The equation that will give a system leading to no solutions will be a system that equates the exact sum of 3x + 4y to another value
Mathematically, that will be;
3x + 4y = -10

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)
