A boat can travel 10 miles downstream in the same time it
can travel 3 miles upstream. The speed of the river
current is 2 miles per hour. Which equation could you use
to find the speed of the boat in still water?
Answers
Answer:
[tex]\frac{10}{x+2} = \frac{3}{x-2}[/tex]
Step-by-step explanation:
The 10 represents the speed traveling downsteam while the 3 represents speed upstream. Downstream you have the help of the current, so it would be x + 2, upstream you are working against the current so it would be x - 2.

Answers
Answer:
LatTisha works as a Lifeguard
Zack works as a clerk at a grocery store
Steve works as a food server
Mitchel is a construction worker
Step-by-step explanation:
The parameters of the question are;
The names of the four friends are; LaTisha, Zack, Steve, and Michelle
The jobs found are; Food server, Lifeguard, Construction worker, and Clerk at a grocery store
1. The food server person likes his work
2. Zack and the lifeguard have known each other for years
3. Mitchel and the lifeguard are outside most of the time
4. LaTisha and the person working construction met on their job last summer
5. Neither Zack nor the food server worker worked last summer
We have;
Using known names,
Famale names are; LaTisha and Michelle
Male names are; Steve and Zack
Therefore
The food server worker is a guy, not Zack but likely Steve
Mitchel works outdoors, therefore, she works in the other outdoor employment which is construction
The remaining two occupations are;
Lifeguard and Clerk at a grocery store
Given that Zack is not the lifeguard, we have;
Zack is the clerk at a grocery store
LatTisha is the Lifeguard

Answers
Answer:
Final amount = $5357.52
Step-by-step explanation:
Formula to be used,
Final amount = [tex]\text{Initial amount}\times (1+\frac{r}{n})^{nt}[/tex]
Here, n = number of compounding in a year
t = Duration of investment
Now we substitute the given values in the question.
Final amount = [tex]1210(1+\frac{0.115}{12})^{12\times 13}[/tex]
= [tex]1210(1.009583)^{156}[/tex]
= 1210(4.4277)

Write a function rule for the table.
A. p = 7.50h
B. p = h + 15
C. p = 15h
D. h = 7.50p
Answers
Answer:
p = 7.50h
I got this correct, the answer is A. p= 7.50h
Step-by-step explanation:
The answer would be d because every two hours someone works they get $15 and for the equation we must know how much they work for one hour so that it works with the equation (we'd have to simplify it down do how much paid up per hour). so half of 15 is 7.5 so the equation would be p=7.50h (standing for $7.50 per hour).
The correct answer is: [D]: " p = 7.50 h " .
________________________________________________
The pay, "p" , is a function of the hours worked.
When h = 2, (h = number of hours);
the pay, "p" , is equal to " 7.50 * 2 " = 15.00 dollars" ; as shown on table.
When h = 4 ; p = " 7.50 * 4 = 30.00 dollars" ; as shown on table .
When h = 6 ; p = " 7.50 * 6 = 45.00 dollars" ; as shown on table.
When h = 8 ; p = " 7.50 * 8 = 60.00 dollars" ; as shown on table.

If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times. Similarly Rudy and Bloopin will be together 4!=24 times. So the number of ways they are not together is 120-24-24=72 ways.
Hope this helps. :)
Step-by-step explanation:
Spanish:
Si los renos no luchan, hay 5! = 120 formas de alinearlos en línea recta.
De estos, Bloopin y Rudy están juntos en 4! = 24 veces. De manera similar, Rudy y Bloopin estarán juntos 4! = 24 veces. Entonces, el número de formas en que no están juntas es 120-24-24 = 72 formas.

A tabletop in the shape of a trapezoid has an area of 5029 square cenimeters. Its longer base measures 123 cenimeters, and the shorter base is 65 cenimeters. What is the height?
Answers
Answer:
Length of height = 53.5 cm
Step-by-step explanation:
Given:
Area of trapezoid = 5,029 cm²
Length of longer base = 123 cm
Length of shorter base = 65 cm
Find:
Length of height
Computation:
Area of trapezoid = [(a+b)/2]h
5,029 = [(123 + 65)/2]h
5,029 = [(188)/2]h
5,029 = [94]h
