My wife and I are Racing around a 400m track going opposite directions. I am running at 8 m/s and she has a head start of 50 meters running at 5 m/s, how long does it take for us to reach the same point ? Explain.
Answer:
They both meet after 27 s.
Step-by-step explanation:
Length of track = 400 m
speed of man, v = 8 m/s
speed of woman, v' = 5 m/s
Woman is 50 m ahead of man.
Let the time taken to meet is t.
Let the man covered a distance d in time t o the woman covered a distance 400 - 50- d.
[tex]\frac{d}{8}=\frac{400-50-d}{5}\\\\5 d = 8 (350-d)\\\\13 d = 2800\\\\d = 215.4 m[/tex]
The time taken is
[tex]t=\frac{215.4}8}\\\\\\t=27 s[/tex]

Which answer choice is equivalent to the expression below?
–7(2+n) + (-9-6n)
0 -17-9
O
-14-12
0 11+5n
14 + 2n
Answer:
the answer would be -13n-23
Step-by-step explanation:
first you want to distribute the brackets
-7(2+n) = -14-7n
+(-9-6n)
-9-6n
-14-7n-9-6n
combine the n value with an n value and an integer that doesn't have an n value
-7n-6n-14-9
= -13n-23

The retail cost of a TV is 50 % more than its wholesale cost. Therefore, the retail cost is ____ times the wholesale cost.
Answer:
Let the retail cost be x and the wholesale cost be y
Step-by-step explanation:
x = y + 0.50y
x = 1.50y
Therefore the retail cost is 1.50 times the wholesale cost.

If three workers can paint a room in two hours and approximately how long does it take for workers to paint the same room assume the time needed to paint the room is inversely proportional to the number of workers
Answer:
The time taken by the four workers to paint the room is 1.5 hours.
Step-by-step explanation:
3 workers can paint a room in 2 hours
So, 1 worker can paint the same room in 6 hours.
Now the number of workers is 4.
So, the time in which the 4 workers can paint the same room is
= 6/4 = 1.5 hours

Answer:
f(-3.2) = - 7.2
Step-by-step explanation:
f(x) = [x] - 4
f(-3.2) will be ;
Here, we put - 3.2 in place of x as the question is interpreted as the value of f(x) when x = - 3.2
Therefore, we have ;
f(-3.2) = - 3.2 - 4
f(-3.2) = - 7.2
in the parallelogram below x=?
Answer:
20
Step-by-step explanation:
In a parallelogram diagonals bisect each other.
[tex] \therefore \: 6x - 57 = 3x + 3 \\ \\ \therefore \: 6x - 3x = 57 + 3 \\ \\ \therefore \: 3x = 60 \\ \\ \therefore \: x = \frac{60}{30} \\ \\ \therefore \: x = 20[/tex]
Use the method of disk or washer to set up, but do not evaluate, an integral for a volume of the solid obtained by rotating the region bounded by the given curves about the given line.
y=√x and y=x and y=1
Answer:
V = π /2 volume units
Step-by-step explanation:
Volume of y = √x bounded by y = x and y = 1
y = √x
limits of integration ( see Annex )
By simple inspection limits of integration are x = 0 to x = 1
or y = √x and y = x
solving these two equations
x = 0 y = 0 x = 1 y = ± 1
V = ∫ π*f(x)²*dx
V = π * ∫₀¹ x*dx = π * x²/2 |₀¹
V = π * (1/2) - 0
V = π /2 volume units

Answer:
y +3 = 1/5x
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
You have y-intercept point (0, -3) and slope -1/5, so the equation is ...
y -(-3) = -1/5(x -0)
y +3 = -1/5x
Sorry for the blurry picture anyone can help?? That’ll be nice
Answer:
Option 2
Step-by-step explanation:
Since both triangles are similar, that means that the larger triangle's sides are greater than the smaller triangle's sides by a factor. We can see that 10 corresponds to x, so in the proportion 10 and x must be on the same side. That rules out option one and three. Now, we see that 7 corresponds to 14 and 6 corresponds with 12, so the other side must have 6 and 12 on the same side or 7 and 14 on the same side. We see that the only option that satisfies this criteria is Option 2.
Answer:
Option 2 - [tex]\frac{10}{x} =\frac{7}{14}[/tex]
Step-by-step explanation:
So, lets just look at the two traingles, find the difference, then see if the graphs will give us the same difference.
So lets see.
One side of triangle ABC is 6. The same side of triangle DEF is 12.
Another side of triangle ABC is 7. THe same side of trinalge DEF is 14.
The final side of trinalge ABC is 10. The same side of triangle DEF is x.
We only need to compare a single side of these to find the difference:
12/6=2
14/7=2
This is very simple.
However, lets shift this into what they wrote.
So we know that the difference between each side is 2.
ALL sides are like this.
We know that both 12/6 and 14/7 equal the same thing, so tecnically, they are equal:
12/6=14/7
This is the same with 10/x as well.
So:
10/x=14/7
10/x=12/6
So we know that the difference from ABC to DEF is 2. But the difference from DEF to ABC is the opposite, 1/2.
Knowing this:
x/10=6/12 is the same thing as 10/x=12/6. And x/10=7/14 is the same thing as 10/x=14/7
So our answers can also be:
x/10=7/14
x/10=6/12
This looks like option 2.
Hope this helps!

What is a, the standard error of the estimate? Include 2 decimal places.
Answer:
248.96
Step-by-step explanation:
From this regression output we have the MS Residual or mean squared error to be equal to 61983.1
the question requires us to find the standard error of the estimate. The standard error of the estimate can be gotten by finding the square root of the MSE.
[tex]\sqrt{61983.1}[/tex]
= 248.96
the standard error of the estimate = 248.96

Determine whether the events are independent.Numbers are written on slips of paper in a hat; one person pulls out a slip of paper without replacing it, then a second person pulls out a slip of paper.Independent Not independent
Answer:
Not independent
Explanation:
Two events are not independent/dependent if the result of one event affects the outcome of the other. In the case above, numbers are picked without replacement, therefore if one slip is picked then the other slip will be picked(slips are picked only once not twice or more as in independent events). Events would be independent if there was a replacement.
