In a river, a trout passed beneath a woman who was swimming at 1,800 centimeters per minute. The trout swam 8,000centimeters directly upstream at a constant velocity. It swam that distance in 0.8minutes. What was the trout's velocity?
Write your answer as a whole number.
centimeters per minute upstream
Answer:
It would approximately be 3.73 m/h
Step-by-step explanation:
0.8 mins is 48 seconds
I then divided 8000 by 48 seconds to see how many cm it traveled per second.
It traveled 166.666666667 cm per second
I then converted cm to feet
so it was 5.468066491699474 feet per second
I then converted feet to miles, so it was 0.0010356186537309611598 miles per second.
Then I multiplied it by 60 so it was 0.06213711922 miles per minute.
Finally I multiplied it by 60 again to make it 3.72822715343 miles per hour.
I rounded it to the nearest hundredth making it 3.73 m/h

Tim explained a function in words and Paul wrote an equation.
Tim
The amount of money in a savings account increases at a rate of $225 per month. After eight months, the bank account has $4,580 in it.
Paul
y−1,400=56(x+26)
Whose function has the smaller y-intercept?
Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780
Answer:
Tim's with a y-intercept of $2,780
Step-by-step explanation:
To find Paul's y-intercept, solve the equation y-1400=56(x+26) for y. Then use the standard format for a linear equation y=mx+b to determine the y-intercept which would be b.
Step 1. Get y by itself by adding 1,400 to both sides.
y-1400 + 1400 = y
56(x+26) + 1400 = 56(x+26) + 1400
New equation y = 56(x+26) + 1400
Step 2. Distribute 56(x+26)
56(x+26) = 56 * x + 56 * 26 = 56x + 1456
New equation y = 56x + 1456 + 1400
Step 3. Simplify.
y = 56x + 2856
Paul's y-intercept would be 2856 because when y=0 x=2856
To Find Tim's y-intercept, subtract 225 * 8 from 4580.
225 * 8 = 1800
4580 - 1800 = 2780

6-3(x+2)>15 solving inequalities
Answer: x < - 5
Step-by-step explanation:
6-3(x+2) > 15 [substract six from both sides]
-3(x+2) > 15 - 6 [divide both sides by -3; flip greater than sign to less than]
x + 2 < - 3 [subtract two from both sides]
x < - 5

Step-by-step explanation:
Number 1
180° = x + 70° + 55° + 30°
180° = x + 155°
x = 180° - 155°
x = 25°
Number 2
x° = 93°
y° = 47°
z° = 180° - 47° - 93°
z° = 180° - 140°
z° = 40°

Jeanette earn $33 in 8 hours. At the rate, how much would she earn in 5 hours?
Answer:
If you made $33 in 8 hours, then you should divide 8 into 33 to see how much you make per hour. 8÷33= (explaining how to get answer) can 8 go into 3? No. put a zero on top of the first three. Now can 8 go into 33? yes, 4 times, 4×8= 32, so we have 1 left over. add 2 decimals to the number so that it is $33.00, (still that same number just with zeros on the end). So far the answer is $04.??. How many times can 8 go into 10? 1 time with 2 left over, so write the one on top of the .0! Now with 2 left over we have to see how many times 8 can go into 20, 8×2= 16 16+8=24, so it can only go in 2 times without going over 20. Now that we have rounded it up to 2 decimals we don't have to keep going and your answer is
$4.12 times that by 5 and you will get the final answer.

Write a rule in both coordinate notation in vector notation to represent the translation of a parallelogram to the right
The rule in vector notation for the translation to the right is described by the following formula:
[tex]V'(x,y) = V(x,y) + (9, -4)[/tex]
Vectorially speaking, a translation is described by the following expression:
[tex]V'(x,y) = V(x,y) + T(x,y)[/tex] (1)
Where:
[tex]V(x,y)[/tex] - Original point.[tex]V' (x,y)[/tex] - Translated point.[tex]T(x,y)[/tex] - Translation vector.By direct inspection we see that parallelogram C'D'E'F' translated to the right is moved 9 in +x direction and 4 in -y direction. Hence, the translation vector is equal to:
[tex]T(x,y) = (9, -4)[/tex]
And the rule in vector notation for the translation to the right is described by the following formula:

The curve above the graph of a sinusoidal function. It goes through the points (-11,0) and (3,0). Find a sinusoidal function that matches the given graph.if needed you can enter pi=3.1416… as pi in your answer otherwise use at least 3 decimal digits.
F(x)=
Considering the zeros, the graph for the sinusoidal function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The zeros given for the function are: [tex]x = -11, x = 3[/tex].For practicality, we are going to define a sine function, which has a zero at x = 0, so we use shifting.The sine function is given by:
[tex]F(x) = A\sin{Bx}[/tex]
In which:
The amplitude is A.The period is [tex]T = \frac{2\pi}{B}[/tex].In this problem:
We suppose an amplitude of 1, thus [tex]A = 1[/tex].The difference between the zeros is 14, so we use a period of 14, thus [tex]T = 14[/tex], and:[tex]\frac{2\pi}{B} = 14[/tex]
[tex]B = \frac{2\pi}{14}[/tex]
[tex]B = \frac{\pi}{7}[/tex]
Thus:
[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]
Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).

How to solve linear equation
You can use elimination and substitution method
EXAMPLE :
Given :
2x + y = 5
3x - 5y = 1
2x + y = 5 (× -5)
3x - 5y = 1
__________
-10x - 5y = - 25
3x - 5y = 1
____________ _ (elimination)
-13x = - 26
x = - 26/-13
x = 2
Substitution x = 2 to 2x + y = 5 :
2x + y = 5
2(2) + y = 5
4 + y = 5
y = 5 - 4
y = 1
The circle graph shows the results of a survey. Of those surveyed, 80 said yes. About how many people were surveyed?
Answer:
134 people
Step-by-step explanation:
80 / .6 = 133.333
Answer:
134 people
Step-by-step explanation:
we can use cross multiplication to solve this problem:
we know that 60% is 80 people and 40% is x people (we put x because we don't know the exact number of how many people yet)
now we set it up:
[tex]\frac{80}{60}[/tex] = [tex]\frac{x}{40}[/tex]
= 60x = 3200
= x = 53.33333
now we add the two numbers of people up:
53.33333 + 80 = 133.3333
since it is a decimal, it would be safer to assume that there are 134 people
