A motorboat travels 172 km in 3 hours going upstream and 372 in 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Answers
Answer:
The rate of the boat is 75.17 km/h and the rate of the stream is 17.83 km/h
Step-by-step explanation:
System of Equations
Let's call:
B = speed (rate) of the boat in still water
S = speed (rate) of the stream
The boat travels 172 km in 3 hours when going upstream, that is when the speed of the stream subtracts its own speed. The speed is the distance divided by the time, thus:
[tex]\displaystyle B-S=\frac{172}{3}[/tex]
Multiplying by 3:
3B - 3S = 172 [1]
The boat travels 372 km in 4 hours downstream when the speed of the current adds to its own:
[tex]\displaystyle B+S=\frac{372}{4}=93[/tex]
B + S = 93
Solving for B:
B = 93 - S [2]
Substituting in [1]
3(93 - S) - 3S = 172
Operating:
279 - 3S - 3S = 172
279 - 6S = 172
Subtracting 279:
- 6S = 172 - 279
- 6S = -107
Multiplying by -1 and solving for S:
[tex]S = \frac{107}{6}\approx 17.83\ km/h[/tex]
From [2]:
[tex]B = 93 - \frac{107}{6}[/tex]
[tex]B=\frac{451}{6}\approx 75.17\ km/h[/tex]

A hot air ballon went from an elevation of 6,669 feet to an elevation of 3,402 in 54 minutes. What was its rate of descent?
Answers
Answer:
elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!

They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.

Next
Answers
Step-by-step explanation:
6x - 15 = 75, 6x = 90, x = 15.
2(2x - 1) = 46, 2x - 1 = 23, x = 12.
x + (x - 10) = 26, 2x = 36, x = 18.
5x - 3x = 10, 2x = 10, x = 5.
Hence the equations
in increasing order of x-values are:
5x - 3x = 10,
2(2x - 1) = 46,
6x - 15 = 75, and
x + (x - 10) = 26.
Answer:
5x - 3x = 10
2(2x - 1) = 46
6x - 15 = 75
x+(x - 10) = 26

what’s the hypotenuse
Answers
explanation:
pythagorean theorem to find the hypotenuse ( which is c)
a^2 + b^2 = c^2
let’s just say a=5 and b = 12
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2 -> take the square root of both sides
√169 = √c^2
c = 13
OR you can memorize a few pythagorean triples and know 13 is the hypotenuse bc 5-12-13 is a pythagorean triple so 13 is the hypotenuse

Simplify: c5•c3•c3
a) C45
b) 3c11
c) C11
d) None of the above
Answers
Answer: C
Step-by-step explanation:
I assume you mean c to the power 5, c to the power 3, and c to the power 3. Well, c^5xc^3xc^3 is c^11. Here's why. When multiple terms that have exponents in them and have the same base are multiplied, you just have to add the exponents. Here's the logic behind this (I'm using another example). If you have 6^3x6^5, your answer will be 6^8 because this can be rewritten as (6x6x6)x(6x6x6x6x6). This is the same thing as 6^8. So, I hope this made sense and your answer will be c.
The requried, simplified expression of [tex]c^5 * c^3 * c^3[/tex] is [tex]c^{11}[/tex]. Option C is correct.
When we have a multiplication of powers with the same base, we can apply the rule of exponents that states: when multiplying powers with the same base, we add their exponents.
In this case, the base is 'c', and we have three terms: c^5, c^3, and c^3. To simplify the expression, we add the exponents:
[tex]c^5 * c^3 * c^3 = c^{5+3+3} = c^{11}[/tex]
So, the simplified form of the expression [tex]c^5 * c^3 * c^3[/tex] is [tex]c^{11}[/tex].
In option b) [tex]3c^{11}[/tex], the coefficient of '3' indicates that we have three terms of [tex]c^{11}[/tex], which is not the case in the original expression.
Therefore, the correct answer is c) [tex]c^{11}[/tex], as we simplified the expression to a single term with the base 'c' raised to the power of 11.
