Denise has 6 hours to spend for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 7mph and walks back at a speed of 3 mph, how long should she plan to spend walking back?
Answer:
She walks back for 4.2 hours
Step-by-step explanation:
Notice that we don't know the distance of the race (so let's name it "d").
She clearly would spend less time running (t1) the distance d at 7 mph, than when coming back walking (t2) at 3 mph.
But we know that the addition of both times must be 6 hours which is what she has to spend:
t1 + t2 = 6
Considering the equation that relates distance (D), time(t) , and speed (v) as:
v = D/t
we can solve for the times t1 and t2 in each trip (running vs walking){
t1 = d/7
t2 = d/3
then when we add these two equations term by term, we get:
t1 + t2 = d/7 + d/3
extract d common factor;
t1 + t2 = d (1/7 + 1/3)
replace t1 + t2 with the 6 hours:
6 = d (10/21)
multiply both sides by 21, and divide both sides by 10 to isolate d:
21 * 6 / 10 = d
d = 12.6 miles
Now knowing the distance she run and walked, we can find the time she spent walking back (t2)
t2 = 12.6 /3 = 4.2 hours
A spaceship traveled 1/2 of a light-year and stopped at a space station. Then it traveled 1/12 of a light-year further to a planet. How far did the spaceship travel in all?
Answer: 7/12 a light year I believe
Step-by-step explanation:
So what you do is you make the denominators of 1/2 and 1/12 the same which would be 6/12 and 1/12.
You then add them together and you get 7/12

Answer:
(24x - 48y + 10) / 26 = a
Step-by-step explanation:
-12(-2x+4y) = 26a - 10
24x - 48y = 26a - 10
24x - 48y + 10 = 26a
(24x - 48y + 10) / 26 = a

4) Line L has equation y = 4x - 7, and line M is parallel to line L and passes through the point (2,15). Determine the equation of line M. A) y = 4x + 7 B) y = 2x + 7 ©). y = 4x + 15 D) y = 2x + 15
Answer:
the answer is A.y=4x+7
Step-by-step explanation:
Line M is parallel to the line L, so the equation for line M isy=4x+b
Plug in the coordinates of the point (2,15) , you get:
15=4*2+b
Solve that to get b=7
Therefore the equation of line M is y=4x+7
Lydia invested $8,300 in an account paying an interest rate of 2.2% compounded
daily. Assuming no deposits or withdrawals are made, how long would it take, to the
nearest tenth of a year, for the value of the account to reach $12,690?
Number of years taken to reach the amount of $12,690 is 5 days,
What is Compound interest?Compound interest is the interest which is calculated on both the initial principal and the accumulated interest from previous periods. It can be easily understood as interest on interest.
[tex]A= P(1+\frac{r}{n})} ^{nt}[/tex]
Principal amount invested by Lydia = $8,300
Rate of compound interest per day =2.2%
To find the number of years that have taken to reach the amount value of $12,690 .
By using compound interest formula,
[tex]A= P(1+\frac{r}{n})} ^{nt}[/tex]
[tex]12690 = 8300(1+ \frac{2.2}{365})^(365*t)[/tex]
[tex]\frac{12690}{8300}=(1.000060274)^{365*t}[/tex]
Taking log on both sides, we get,
log(1.5289156627) =365*t log(1.000060274)
log(1.5289156627)/log(1.000060274)= 365*t/log(1.000060274)⇒
0.184383 - 0.00002618= 365*t
⇒1843.5 =365*t
⇒t=5 days.
Hence, number of years taken to reach the amount of $12,690 is 5 days,

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 3 to 2. If there were 1833 yes votes, what was the total
number of votes?
Answer: 1,222
Step-by-step explanation:
I would set this up as a fraction
3/2=1833/x
I would divide 1833 by 3 to see what the multiple is that would be used to find the equivalent fraction. Then multiply that number by 2 to solve for x.
Another option is to cross multiply
3x=2(1833)
1833*2=3666
Divide 3x by 3 to get x alone
Divide 3666 by 3 to get answer

. Find all values of x that will make ∠A an obtuse angle given
m∠A = 12x - 6
Answer:
(8, 15]
Step-by-step explanation:
If ∠A is bigger than 90 then that means 12x-6 > 90
12x > 96
x > 8
and we know that the angle must be between 0 and 180. so 12x < 186
x <= 15
A car manufacturer produced 5.000 cars for a limited edition model Dealers sold all of these cars at mean price of $36,000 with a standard deviation of $3,000. Suppose we were to take random samples of 9 of these cars and calculate the sample mean price for each sample. Calculate the mean and standard deviation of the sampling distribution of .
Answer: Mean = $36,000 and standard deviation = $1000.
Step-by-step explanation:
The mean and the standard deviation of the sampling distribution of the sample mean:
[tex]Mean=\mu\\\\Standard\ deviation = \dfrac{\sigma}{\sqrt{n}}[/tex] , where n =sample size.
Here, we are given
[tex]\mu=\$36000,\ \ \sigma=\$3,000[/tex]
n= 9
Then, the mean and the standard deviation of the sampling distribution of the sample mean:
[tex]Mean=\$36000,\ \ Standard\ deviation=\dfrac{3000}{\sqrt{9}}=\dfrac{3000}{3}=\$1000[/tex]
Hence, Mean = $36,000 and standard deviation = $1000.

It would be very hard to graph this equation correctly as without factoring both the numerator and denominator it would be hard to account for all of the information.
x2−5x+6x2−2x−3x−6(x−2)(x−3)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Note that you need to use parentheses around the numerator and around the denominator: f(x) = (2x^2+4)/(x^2+5x+6)
Division by zero is undefined, so x≠-2 and x≠-3.
Vertical asymptotes: x=-2, and x=-3
As x approaches ∞, f(x) approaches 2.
As x approaches -∞, f(x) approaches 2.
Horizontal asymptote: y=2
