The way to calculate this percentage is to first write down the following equation

17 divided by 20

when finished, the answer is .85, then once you have this answer you translate that to a percent making it 85%. So the answer to this problem is 85%

I hope this answer helps you figure out more questions like this in the future, if you have any questions, feel free to ask me :)

Last month, Claire's bank statement said that she overdrew her account. Her bank balance was -45.32−45.32minus, 45, point, 32 eu

The question is incomplete and the full version can be found online.

Answer: Janeth has 17.92 dollars in her account.

Step-by-step explanation:

The question states that, after having been told that she overdrew her account the previous month, Claire´s new bank balance is 17.92 dollars. Having said that, the question is what does that new amount means, and the options given are that she overdrew her account by 17.92 dollars, or that she has 17.92 dollars in her account.

The answer couldn´t be that Claire overdrew her account again, by 17.92 dollars this time, because if that was the case, her new balance would be the addition of the previous -45.32 dollars plus the new -17.92 dollars:

-45.32-17.92=-63.24

This means that the new amount would be -63.24. Since the number is positive, it represents the money she has in the account: 17.92 dollars

If S = {x,y,4,9,?) , which could describe U ?

Blizzard [7]

Answer:- A) U= { keys on a keyboard}

Explanation:-

A set is a well defined collection of objects.
A Universal set is the set containing all objects and all other sets are subsets of the universal set. It is denoted by 'U'.

Given set : S = {x,y,4,9,?}

Clearly it contains numbers (4,9), alphabets(x,y) and punctuation mark(?).

Thus the universal set of the given set must contain all of them.

Thus U={keys on a keyboard}

Which logarithmic equation is equivalent to the exponential equation below?

aleksandr82 [10.1K]

Option B: $\ln 6=5 x$ is the correct answer.

Explanation:

The exponential equation is $e^{5 x}=6$

If $f(x)=g(x)$ , then $\ln (f(x))=\ln (g(x))$

Thus, the equation becomes

$\ln \left(e^{5 x}\right)=\ln (6)$

Applying log rule, $\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)$ and thus the equation becomes

$5 x \ln (e)=\ln (6)$

Since, we know that, $\ln (e)=1$ , using this we get,

$5 x=\ln (6)$

Hence, the logarithmic equation which is equivalent to the exponential equation $e^{5 x}=6$ is $\ln 6=5 x$

Thus, Option B is the correct answer.

Math help ASAP!! Also both drop down boxes are the same.

Llana [10]

Answer:

Domain: amount of fuel in the airplane's tank (in gallons)

The set of all real numbers from 0 to 200

Range: weight of airplane (In pounds)

The set of all real numbers from 3000 to 4400

Step-by-step explanation:

We have the following function

$W=7F+3000$

Where W represents the weight of the plane in pounds and F represents the amount of fuel in gallons.

The domain of a function is the set of values "F" that can be entered in a function W(F) to obtain an output value of W.

In this case the range of the function W(F) is the whole set of values $W_1, W_2, W_3, ..., W_n$ that are obtained for $F_1, F_2, F_3, ..., F_n$

Note that, in this case, equation W(F) is used to obtain the weight of the airplane from the amount of fuel F.

Then the domain of the function is the amount of fuel in the airplane tank (in gallons). Since the tank can only hold up to 200 gallons, and there are no negative volume units, then the domain is all real numbers between 0 and 200.

The range of the function is the weight of the plane (in pounds). Note that the minimum weight of the airplane with 0 gallons of fuel is 3000 pounds and the maximum weight with the full tank is 4400 pounds.

Then the range is all real numbers between 3000 and 4400
