Answer: 1) 9 days

2) a)37.5%

b)50%

c) 33.33%


Step-by-step explanation:

1) - Let's call:

x: number of days the company supposed to finish the order.

- You know that the company had to produce 40 items daily, but it produced 20 items more daily and finished the order 3 days ahead of time. Therefore, you can express this as following:

40x=(40+20)(x-3)\\40x=60(x-3)

- Solve for x:

40x=60x-180\\-20x=-180\\x=9

(The answer is 9 days)

2) a) The percent that belongs to three people if eight eight people share equally in an inheritance, can be calculated as following:

\frac{3}{8}*100=37.5%

b) The percent that belongs to three people if six people share equally in an inheritance (because two of the people are disinherited) can be calculated as following:

\frac{3}{6}*100=50%

c) - The increase goes from 1/8 to 1/6, therefore, you must subtract them:

\frac{1}{6}-\frac{1}{8}=\frac{1}{24}=0.04167

- Divide the result by 1/8 and multiply by 100 to obtain the percent:

\frac{0.04167}{\frac{1}{8}}*100=33.33%

How long would it take for a ball dropped from the top of a 484-foot building to hit the ground?
pochemuha

Answer:

First, convert the ft to standard units of meters.

1 foot = 0.3048 meters

Therefore,

484 ft = 147.5232 meters

Then, we will use the laws of motion to calculate the time:

x = 0.5 at^2

where:

x is the displacement

a is the gravity (9.8 m/sec^2)

t is the time taken

Substitute in the equation with the givens to calculate the time as follows:

147.5232 = (0.5 x 9.8) t^2

t^2 = 147.5232 / (0.5 x 9.8)

t^2 = 30.11 seconds

t = 5.49

HOPE THIS HELPED!!!!!!!XDD

Marianna [84]
To find the average, divide change in weight by change in weeks. 
(149-134)/(8-13)
You should get a negative number, because he loses weight.

In what order must you preform the operations indicated by a negative rational exponent?
Svet_ta [14]

The operations referred to are likely

• raising to a <em>power</em> (the numerator of the exponent)

• taking a <em>root</em> (the denominator of the exponent)

• finding a <em>reciprocal</em> (because the exponent is negative)

They can be performed in any convenient order. It often works well to deal with small positive integers, so if one or more of these operations lets you proceed with a small positive integer for the remaining operations, that would be the one you'd perform first.

_____

A computer performing operations with a negative rational exponent may do so using logarithms. That is, the log of the base will be multiplied by the exponent, then the antilog found. The exponent itself will likely be treated as a floating point number, unless coding specifically indicates otherwise.

/sqrt{4x+15=3/sqrt{x}<br><br>what does x equal?
irga5000 [103]

\frac{\sqrt{4x+15} }{\sqrt{x} } =3

Answer:

3

Step-by-step explanation:

Multiply both sides by x to get rid or the denominator: \sqrt{4x+15}=3\sqrt{x}

Get rid of the square root by squaring both sides:\left(\sqrt{4x+15}\right)^2=\left(3\sqrt{x}\right)^2 = 4x + 15 = 9x

Just solve for x.

<em>Hope this helps!!</em>
