On average, 4 20 of the money you spend on a product pays for the packaging. What is this fraction when you cancel it down?
Ostrovityanka [42]

Answer:

\frac{1}{5}

Step-by-step explanation:

We are given,

The fraction of money spent on a product = \frac{4}{20}.

Since, we have that,

20 = 4 × 5

Simplifying this equation to get the required fraction i.e. \frac{4}{20}, we get,

\frac{4}{20}=\frac{1}{5}

Thus, the fraction after canceling down gives the answer \frac{1}{5}.

Find the slope of the line that passes through the pair of points. (4, 5), (10, 0) 5/6 -5/6 -6/5 6/5
yanalaym [24]
Use the slope formula \dfrac{y_2-y_1}{x_2-x_1} and plug in the values for x and y.
\dfrac{0 - 5}{10 - 4} = \dfrac{-5}{6}

Jeff uses 3 fifth- size strips to model 3/5. he wants to use tenth size strips to models an equivalent fraction. how many tenth
Anuta_ua [19.1K]
He will need 6 tenth size strips because if you put 3/5 vertically with another fraction beside of it that had the numerator blank and the bottom 10. You do this because Jeff uses fifth size strips so 5 represents the strips and you need tenth size strips so you find our numerator for the tenth size strips. You find out how many times 5 can go into 10 or 5 times what equals 10 and it's 2. So whatever you do to the bottom you do to the top. You times 5 by 2 at the bottom and get 10 for the tenth size strips and 3 times 2 at the top yoi get 6 and that is 6/10 is your answer

The measurement of the radius of the end of a log is found to be 9 inches, with a possible error of 1/2 inch. Use differentials
enot [183]

Answer:

\pm 9in^2

Step-by-step explanation:

We are given that

Radius of end of a log, r= 9 in

Error, \Delta r=\pm 1/2in

We have to find the error in computing the area of the end of the log by using differential.

Area of end of the log, A=pi r^2

\frac{dA}{dr}=2\pi r

\frac{dA}{dr}=2\pi (9)=18\pi in^2

Now,

Approximate error in area

dA=\frac{dA}{dr}(\Delta r)

Using the values

dA=18\pi (\pm 1/2)

\Delta A\approx dA=\pm 9in^2

Hence, the possible propagated error in computing the area of the end of the log=\pm 9in^2
