Answer:

The error is the number of zeroes is  used as the exponent instead of the  number of places the decimal is  moved

Step-by-step explanation:

Answer:

The correct answer is 2.32*10^6. The exponent 10^4 is wrong since the decimal place was moved six from the right. Additionally, the exponent number isn't dependent on the amount of zeros, but the amount of times the decimal place was moved.

Step-by-step explanation:

Each place you move the decimal, you have to add or subtract one to the exponent.

If you move the decimal place towards the left, you add one.

If you move the decimal place toward the right, you subtract one.

The exponent number isn't dependent on the amount of zeros, but the amount of times you moved the decimal place. To get from 2,320,000 you must move the decimal place 6 times to the left to get 2.32. Hopes this helps!

A toy factory sold 120,587 toys in 25 days. If each toy was sold for $58, about how much money did the factory earn in 25 days?
Rina8888 [55]
<h3>Answer: $7,018,000</h3>

This value is a little over 7 million dollars

======================================================

Explanation:

120,587 rounds to 121,000 when rounding to the nearest thousand.

The instructions don't mention rounding 58, so we'll leave it as that

Multiply the values to get

58*121,000 = 7,018,000

which is the estimate of how much money was earned.

-----------

The actual amount of money earned is

58*120,587 = 6,994,046

which isn't too far off of our estimate.

-----------

Note: the value of 25 days is never used. You could have any other number of days you want, and the answer is still the same. This value is probably either filler or some kind of distraction.

adoni [48]

Answer:

6.517%

Step-by-step explanation:

This is a multi-year investment and we are not working with a $1 initial investment. There is no mention of compounding so we will use formula A=P0⋅(1+r)N with A=$18,434 and P0=$14,320. We do not know the value of r. However, N=4 years. Substituting the values we have $18,434=$14,320⋅(1+r)4. Divide both sides of the equation by $14,320. Next, take the fourth root of both sides of the equation and subtract 1 to find the decimal form of r.

$18,4341.287291.065170.06517=$14,320⋅(1+r)4=(1+r)4=1+r=r

Finally, convert r to a percent.

r=0.06517×100%=6.517%
