A salmon is swimming in a river that is flowing downstream at a speed of 2 miles per hour. The slamon can swim 12 miles upstream in the same amount of time it would take 24 miles downstream. What is the speed of the salmon in still water?
Answer:
The speed of the salmon in still water is 6 mi/h
Step-by-step explanation:
When an object moves with a speed So (So measured in still water) in a river with speed Sr:
If the object moves along the current (downstream), then the actual speed of the object will be:
S = So + Sr
If the object moves upstream, then the velocity will be:
S = So - Sr
In this case we know the speed of the river downstream is 2 mi/h
Sr = 2mi/h
And we know that the salmon can swim 12 miles upstream in the same time (T) that it can swim 24 miles downstream.
Here you need to remember the relation:
Distance = Time*Speed.
Then we know that:
24 mi = (So + 2mi/h)*T
12 mi = (So - 2mi/h)*T
Now we can take the quotient of these two equations to get:
(24mi/12mi) = ( (So + 2mi/h)*T)/((So - 2mi/h)*T)
2 = (So + 2mi/h)/(So - 2mi/h)
Let's multiply both sides by the denominator of the right part:
2*(So - 2mi/h) = (So + 2mi/h)
2*So - 4mi/h = So + 2mi/h
Now we need to isolate So, the speed of the salmon in still water:
2*So - So = 2mi/h + 4mi/h
So = 6mi/h
The speed of the salmon in still water is 6 mi/h

A website administrator is considering using one of the two models above to predict the total number of purchases, P, made x weeks after the website's advertisin(g campaign begins. How many more purchases are predicted by the exponential model than by the linear model 5 weeks after the advertising campaign begins?
P = 2000x
P= 500(2^x)
A. 6000
B. 8000
C. 10,000
D. 16,000
9514 1404 393
Answer:
A. 6000
Step-by-step explanation:
Use x=5 and evaluate each model.
Linear model
P = 2000(5) = 10,000
Exponential model
P = 500(2^5) = 500(32) = 16,000
The difference in the predicted value is ...
16,000 -10,000 = 6,000 . . . more are predicted by the exponential model

At a party, if 1/5 of one sheet
cake is uneaten and Tom eats
1/6 of the uneaten cake, what
fraction of the original cake
did Tom eat?
Answer:
Step-by-step explanation:
He eats 1/6 or 1/5 of the original cake.
All you need to do to get the answer is multiply the denominators.
1/5 * 1/6 = 1/30
If there was something in the numerators. you would multiply them too.
So suppose the two fractions were 3/5 and 2/7
The answer would be 3 * 2 / 5 * 7 = 6 / 35
General rule
When multiplying two fractions, multiply numerator * numerator / (denominator * denominator).

The value V of a certain automobile that is t years old can be modeled by V(t) = 14,651(0.81). According to the model, when will the car be worth each of the following amounts?
(a) $8000
(b) $6000
(c) $1000
- The car will be worth $8000 after years.
(Type an integer or a decimal rounded to the nearest tenth as needed.)
Answer:
a) The car will be worth $8000 after 2.9 years.
b) The car will be worth $6000 after 4.2 years.
c) The car will be worth $1000 after 12.7 years.
Step-by-step explanation:
The value of the car after t years is given by:
[tex]V(t) = 14651(0.81)^{t}[/tex]
According to the model, when will the car be worth V(t)?
We have to find t for the given value of V(t). So
[tex]V(t) = 14651(0.81)^{t}[/tex]
[tex](0.81)^t = \frac{V(t)}{14651}[/tex]
[tex]\log{(0.81)^{t}} = \log{(\frac{V(t)}{14651})}[/tex]
[tex]t\log{(0.81)} = \log{(\frac{V(t)}{14651})}[/tex]
[tex]t = \frac{\log{(\frac{V(t)}{14651})}}{\log{0.81}}[/tex]
(a) $8000
V(t) = 8000
[tex]t = \frac{\log{(\frac{8000}{14651})}}{\log{0.81}} = 2.9[/tex]
The car will be worth $8000 after 2.9 years.
(b) $6000
V(t) = 6000
[tex]t = \frac{\log{(\frac{6000}{14651})}}{\log{0.81}} = 4.2[/tex]
The car will be worth $6000 after 4.2 years.
(c) $1000
V(t) = 1000
[tex]t = \frac{\log{(\frac{1000}{14651})}}{\log{0.81}} = 12.7[/tex]
The car will be worth $1000 after 12.7 years.

6/7 or 85.7%Step-by-step explanation:
As per table experimental probability of sum of two numbers > 5 is 6 out of 7.
So in number, the probability is:
p = 6/7 or 85.7%Which function shows the function f(x) = 3^x being
translated 5 units to the left?
A. f(x) = 3^x – 5
B. f(x) = 3^(x+5)
C. f(x) = 3^(x - 5)
D. f(x) = 3^x + 5
Answer:
B.
Step-by-step explanation:
When you want to move a function on a graph from left to right, you "move" the x, and when moving the x; it's the opposite. So, C would move the function 5 units to the right because it is subtracting.
The correct option will be f(x) = 3^(x - 5)
What is translation?A translation is a transformation that moves every point in a figure the same distance in the same direction.
Given that, the function f(x) = 3ˣ, being translated 5 units to the left.
Since, the function is being translated in left, therefore, we subtract 5 from x,
i.e. f(x) = 3⁽ˣ⁻⁵⁾
Hence, f(x) = 3⁽ˣ⁻⁵⁾ is the function shows the function f(x) = 3ˣ being
translated 5 units to the left.

Which chocolate chip cookies have the greater spread in the number of chips per cookie?

Answer:
Reduced fat had the greater spread.
Step-by-step explanation:
A poll was conducted during the final game of the basket season to determine whether fans wanted to see the defending champions win the game or the challenging team win the game. From the poll, 216 of the 374 residents sampled from urban areas want the defending champions to win the game. In more rural areas, 304 of the 466 residents polled want the defending champions to win the game. Assuming lo an has nothing to do with team preference, the probability that the data gathered was the result of chance is calculated to be 0.03. What is the correct interpretation of this calculation?
There will be a significant difference between the two proportions. A further explanation is given below.
As shown by the data, families in remote regions are much more likely to desire the protecting winners to control the tournament than individuals throughout large cities, and this difference is statistically substantial.Throughout this case, it's because the p-value of further 0.03 would be significantly less than the threshold of 0.05 significance. As a result, we may claim that perhaps the results are statistically significant at such a 0.05 range.
Thus the above is the appropriate solution.
