Answer: Since the track is .25 miles, the runner would run 1.5 miles. Since a mile is equal to 7920.

Answer: Since you run 6 times around the 0.25 mile track,

6 * 0.25 = 1.5 miles

1 mile = 5280 feet

1.5 miles = 7920 feet

6 * 0.25 = 1.5 miles

1 mile = 5280 feet

1.5 miles = 7920 feet

A football running back ran a play in a game and gained 6 yards. How many feet did he gain? The football player gained [ ? ] feet.

He gained 18 feet.

1 yard = 3 ft, so 3 x 6 = 18

1 yard = 3 ft, so 3 x 6 = 18

Answer:

18 ft

Your favorite stock opened the day's trading at $44.17 per share. When trading closed for the day, your stock was priced at $38.41 per share. If you own 145 shares, what was your profit or loss that day?

Answer:

$835.20

Step-by-step explanation:

First you need to find out how many profit you had at first by multiplying 145 and $44.17.

So, 145*$44.17 = 6404.65

Then find out how much profit you had after it decreased by multiplying 145 and $38.41.

So, 145*$38.41 = 5569.45

Now to find how much profit you lost, you have to subtract $6,404.65 and $5,569.45.

$6,404.65 - $5,569.45 = $835.20

5n + 34 = -2 ( 1 + 7n )

Please solve and show work

5n + 34 = -2(1 + 7n)

Simplify.

5n + 34 = -2 - 14n

Subtract 34 from both sides.

5n = -2 - 14n - 34

Add 14n to both sides.

5n + 14n = -2 - 34

Simplify.

19n = -36

Divide both sides by 19.

n = -36/19

~Hope I helped!~

Simplify.

5n + 34 = -2 - 14n

Subtract 34 from both sides.

5n = -2 - 14n - 34

Add 14n to both sides.

5n + 14n = -2 - 34

Simplify.

19n = -36

Divide both sides by 19.

n = -36/19

~Hope I helped!~

5n + 34 = -2(1+7n)

distribute the -2

5n + 34 = -2 -14n

combine like terms

5n + 14n = -2 - 34

19n = -36

n = -36/19

distribute the -2

5n + 34 = -2 -14n

combine like terms

5n + 14n = -2 - 34

19n = -36

n = -36/19

Eight ten-thousandths of thirty-five million in scientific notation answer

Answer

2.8 × 10⁴

Explanation

Eight ten-thousandths of thirty-five million

Eight ten-thousandths = 8/10,000

= 0.0008

=0.0008 of 35,000,000

=8/10,000 of 35,000,000

=8/10,000 × 35,000,000

=8 × 3,500

=28,000

In scientific notation, 2.8 × 10⁴

Answer:4.375 x

Scientific notation mean that you convert the number into unit. It is easier to read if the number is too big or too small.

Eight ten-thousandths mean 8/10,000 or 8 x

Thirty-five milions mean 35,000,000 or 3.5 x

Then if you divide the second number with the first number you will get:

3.5 x / (8 x = 0.4375 x = 4.375 x

Scientific notation mean that you convert the number into unit. It is easier to read if the number is too big or too small.

Eight ten-thousandths mean 8/10,000 or 8 x

Thirty-five milions mean 35,000,000 or 3.5 x

Then if you divide the second number with the first number you will get:

3.5 x / (8 x = 0.4375 x = 4.375 x

What is the domain and range for y=sqrt(x-4)?

Domain: set of all numbers that can be inputted into a function

So.. x−4≥0

x−4+4≥0+4

x≥4

So this says: "Any number greater than or equal to 4 will result in x-4 being either 0 or some positive number"

So this means that the domain is

{x|x≥4}

This basically says: "the domain is the set of all numbers x such that x is greater than or equal to 4"

In interval notation, the domain is [4,∞)

The range is the set of all possible outputs. We can find the most extreme point of the range by plugging in the most extreme value for the domain

sqrt(x-4) = sqrt(4-4) = sqrt(0) = 0

So the smallest possible output is y=0, which means that the range is

{y|y≥0}

This basically says: "the range is the set of all numbers y such that y is greater than or equal to 0"

In interval notation, the range is

[0,∞)

The function f is such that f(x)=4x-1 find f^-1(x)

Let y=4x-1

The inverse is basically expressing x in terms of y.

y=4x-1 =>

y+1=4x

x=(y+1)/4

Since the inverse is still a function of x, we only have to interchange x and y

inverse of f(x) = f^-1(x) = (x+1)/4

The inverse is basically expressing x in terms of y.

y=4x-1 =>

y+1=4x

x=(y+1)/4

Since the inverse is still a function of x, we only have to interchange x and y

inverse of f(x) = f^-1(x) = (x+1)/4
