Answer:

Suppose the next case.

You want to buy an object from another state or country, you know that the cost of this object is C, and for bringing it from another place, you need to pay a tax, such that you do not know the exact value of the tax, you know that this can be between 3% and 9%.

Then the tax can be written as:

6% ± 3%

then the error is 3%, this means that the percent error is:

(3%/6%)*100% = 50%

Then you know that there is an error of 50% in the tax.

This can be helpful so you can estimate the maximum and minimum cost of tax that you will pay for this purchase.

Also there are a lot of situations where the percent error give us a lot of information.

"a measure of 10 cm with an error of 1 cm"

The percent error is: (1cm/10cm)*100% = 10%

And in a measure of 3cm with an error of 1cm we have:

(1cm/3cm) = 33.33%

In both cases we have the came error, but different percent error.

Then the percent error also tell us how much the error affects our measure.

27? i cant figure out her mistake can anyone help ?
expeople1 [14]
The mess up occurs in one of the first things she says. She first claims that 7^2 +25^2 = 24^2
Wait a minute... slow your roll there.
25 is the hypotenuse, or the longest side of the triangle AND opposite the right angle (but we aren't supposed to know that yet).
The Pythagorean Theorem holds that a^2 + b^2 = c^2, where a & b are the legs of the triangle & c is the hypotenuse. So, she got the formatting correctly, but she switched 24 & 25.
Hope this helps!

nikdorinn [45]

Total earned= $273

Step-by-step explanation:

Giving the following information:

Regular labor hours= $5.25

Overtime labor hours= $5.25*1.5= $7.875

<u>To calculate the total earned, we need to use the following formula:</u>

Regular labor hours= 40*5.25= 210

Overtime labor hours= 8*7.875= 63

Total earned= 210 + 63

Total earned= $273

Which situation is most likely to have a constant rate of change? A. Length of a bead necklace compared with the number of ident
Kipish [7]

Answer:

A. Length of a bead necklace compared with the number of identical beads

Step-by-step explanation:

Using identical beads in a necklace means that the length of the necklace will depend on the total number of identical beads in the necklace.

For each bead added, the length of the necklace will increase a given, constant, amount.  This is a constant rate of change.
