Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no wind.
Answers
Answer:
6.5 mph
Step-by-step explanation:
Given that :
Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no
Wind speed = 2mph
Let time taken to skateboard = t
Speed = distance / time
Distance of 3.375miles against 2 mph wind
Let skate speed = x
skate speed - wind speed=
(3.375 miles / t) + 2mph = x - - - (1)
Distance of 6.375miles with 2 mph wind
(6.375 miles / t) - 2 mph = x - - - - (2)
Equate (1) and (2)
(6.375/ t) - 2 = (3.375/ t) + 2
(6.375 - 3.375) / t = 2 + 2
3 / t = 4
3 = 4t
t = 3/4
t = 0.75
Hence, speed without wind will be :
(3.375 miles / 0.75) + 2mph = x
4.5mph + 2mph = 6.5 mph

“To graph y=2/3x+4, Emaan plots one point at (0,4) and a second point 2 units right and 3 units up at (2,7). He then draws a line through (0,4) and (2,7). What error did Emaan make?”
The “2/3x” area is meant to be a fraction.
Answers
Answer:
The error he made was adding 3 to the y value and adding 2 to the x value, instead of adding 2 to the y value and 3 to the x value.
Step-by-step explanation:
The slope can also be called "rise over run," or the change in y divided by the change in x.
In this situation, the slope is 2/3, meaning that a change in y of 2 units will increase the x value by 3 units.
Emaan switched these values when plotting the points, and did a change in 2 x values with a change in 3 y values.
From the point (0, 4), instead of plotting the point (2, 7), he should have plotted (3, 6).
The error he made was adding 3 to the y value and adding 2 to the x value, instead of adding 2 to the y value and 3 to the x value.

Solve v2 = 47.
please :)
Answers
Answer:
v=± 47=±6.8557
Step-by-step explanation:
(1): "v2" was replaced by "v^2".
(2) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: v^2-(47)=0
The value of v is ± 6.856.
What is a perfect square ?A number when taken square root gives an integer is a perfect square and when a number is not a perfect square and we have taken it's square root the number is an irrational number.
According to the given question v² = 47.
∴ v = ±[tex]\sqrt{47}[/tex].
We know that v is between 6 and 7 but more closer to 7 as [tex]\sqrt{49}[/tex] is ±7 and [tex]\sqrt{36}[/tex] is ±6 we we can write an approximate value of v which is ±6.9 or we can use a calculator for which v = ± 6.856.
