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

How do i graph -7x-2y=-21???

Answers

Answer:

-7/2 is the slope. -10.5 is your starting point on the y-axis. You go from -10.5, up 7 and over to the left 2 times because it's negative.

Step-by-step explanation:

-7x-2y=-21

-2y=7x-21

y=-7/2x-21/2

y=-7/2x-10.5

Hope this helps!

You might want to simplify the equation first. Basically, we'll use y = ax+b instead.

[tex]-7x-2y=-21\\-2y=-21+7x\\y=\frac{-21}{-2}+\frac{7x}{-2} \\y=\frac{21}{2}-\frac{7x}{2}\\y=\frac{21-7x}{2}[/tex]

Should have been like this then you are able to graph.

To graph, you need to find the x-intercept and y-intercept.

(1) Find x-intercept, substitute y = 0

[tex]0=\frac{21-7x}{2} \\0=21-7x\\7x=21\\x=3[/tex]

Thus, the graph has a x-intercept at (3,0). For those who are wondering where does the fractional 2 go, just multiply the whole equation by 2 to get rid of the fraction.

(2) Find y-intercept, substitute x = 0

[tex]y=\frac{21-7x}{2}\\ y=\frac{21-0}{2}\\ y=\frac{21}{2} \\[/tex]

Also 21/2 = 10.5, Thus the graph passes y-axis at (0, 10.5)

Now plot the graph, make a line from x-intercept and y-intercept and you should get like this (Picture below.)

Ingredient 8 servings

Dried split peas: 2 and 1/4 c.
Water: 2 qt
Chopped onion: 3/4 c.
Chopped celery: 1 c.
Ham shank: 2 lb.
The basic recipe for split pea soup serves 8 people. Find the amount of each ingredient needed to serve 32 people.

Answers

Answer:

Dried split peas: 9 cups

Water: 8 quarts

Chopped onion: 3 cups

Chopped celery: 4 cups

Ham shank: 8 pounds

Step-by-step explanation:

Since the basic recipe serves 8 people and you need to serve 32 people, you just multiply each ingredient by 4. (32÷8=4)

Dried split peas: 2 1/4 c.   x 4 = 9 cups

Water: 2 qt  x 4 = 8 quarts

Chopped onion: 3/4 c.  x 4 = 3 cups

Chopped celery: 1 c.   x 4 = 4 cups

Ham shank: 2 lb.  x 4 = 8 pounds

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.
