In his motorboat, Bill Ruhberg travels upstream at top speed to his favorite fishing spot, a distance of 264 mi, in 6 hr. Returning, he finds that the trip downstream, still at top speed, takes only 5.5 hr. Find the rate of Bill's boat and the speed of the current. Let x = the rate of the boat in still water and y = the rate of the current.
Answers
Answer:
The values are [tex]x = 46 miles /hr [/tex]
[tex]y = 4 \ miles / hr[/tex]
Step-by-step explanation:
From the question we are told that
The distance covered is d = 264 miles
The time taken is [tex]t_1 = 6 hours[/tex]
The time taken for the return trip is [tex]t_2 = 5.5 \ hours[/tex]
Generally during the trip toward fishing spot , the velocity is mathematically represented as
[tex]v_t = \frac{d}{t_1 } = x - y[/tex]
=> [tex]v_t = \frac{264}{6 } = x - y[/tex]
=> [tex]x - y = 44 \cdots 1 [/tex]
Generally during the return trip , the velocity is mathematically represented as
[tex]v_r = \frac{d}{t_2} = x+ y[/tex]
=> [tex]v_r = \frac{264}{5.5} = x+ y[/tex]
=> [tex]48 = x+ y\cdots 2[/tex]
add equation 1 and 2
[tex]2x = 92[/tex]
=> [tex]x = 46 miles /hr [/tex]
substituting this into equation 1
[tex] 46 - y = 44 \cdots 1 [/tex]
=> [tex]y = 4 \ miles / hr[/tex]

A bag contains 120 marbles. Some are red the rest are black. There are 19 red marbles for every black marble. How many red marbles are in the bag?
Answers
Answer:
114
Step-by-step explanation:
Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)
19+1= 20
20 units= 120 (Data from 1st sentence)
1 unit= 120/20= 6
19 units= 120-6= 114 (Values solved in working above)
Ans: There are 114 red marbles.

Answer:

any real number
Step-by-step explanation:
your welcome
The correct answer is:
⇒ Any real number for x except 5, and any real number for y.
What is mean by Function?A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value. This means that no x can be mapped to more than one y, so if we have the same number used twice for x, we do not have a function.
Now, For given function is,
This means that 5 cannot be used for x in the other ordered pair.
Since there is no restriction on y in order to be a function, y can be any real number.
Thus, The correct answer is:
⇒ Any real number for x except 5, and any real number for y.

Answers
Answer:
y = 2x - 7
Step-by-step explanation:
y = 2x - 3
Gradient of line w = 2
Gradient of line d = 2
i.e line w and d are parallel.
Equation of line d is:
y - (-1) = 2(x - 4)
y + 1 = 2x - 8
y = 2x - 7

Which equation shows a proportional relationship between x and y?
y = 16
y = 7x
y=−7x−2
y = 9x + 1
Answers
The equation that shows a proportional relationship is y = 7x.
How to find the equation that is proportional?Two variables have a proportional relationship if all the ratios of the variables are equivalent.
In other words, a proportional relationship is one in which two quantities vary directly with each other.
Therefore, a proportional relationship can be represented as y = kx.
where
k = constant of proportionalitythe variables are x and yTherefore, y varies directly as x in a proportional relationship.
Hence, the equation that shows proportional relationship is y = 7x as 7 is the constant of proportionality. y and x are the variables.
