Answer:

Non fiction : Total number of books

= 14 : 42

= 1:3

Step-by-step explanation:

Total number of books = 42 books

Non fiction books = 14 books

The ratio of the number of non-fiction books to the total number of books is :

Non fiction : Total number of books

= 14 : 42

Further simplified

= 1:3

If 12% of a number is 24 what is the number Pls Answer fast
Nadya [2.5K]

Answer:

200

Step-by-step explanation:

12% is equal to 12/100

I would set up something like

12/100= 24/x

to get from 12 to 24, you have to multiply by 2.

do the same for 100 so 100 x 2= 200

2 1/2 x 3 1/5 fast please
vova2212 [387]

Step-by-step explanation:

<u>Let's turn each mixed fraction into an improper fraction:</u>

2 \frac{1}{2} =\frac{2}{2} +\frac{2}{2} +\frac{1}{2} =\frac{5}{2}

3\frac{1}{5} =\frac{5}{5} +\frac{5}{5} +\frac{5}{5} +\frac{1}{5} =\frac{16}{5}

<u>Multiply:</u>

\frac{5}{2} \times \frac{16}{5} =\frac{80}{10}

<u>Simplify:</u>

\frac{80 \div 10}{10 \div 10} =\frac{8}{1} =8

8 is your simplified product.

The results of a test of a metal are shown in the table, with strain in meters per meter, andstress in units called megapascals,
shusha [124]

a.

b.

The metal obey this law for values of strain until 0.05, where we have a linear relationship (each increase of 0.01 in the strain causes an increase of 100 in the stress). After this point, we don't have a linear relationship anymore.

c. Since an increase of 0.01 in the strain causes an increase of 100 in the stress, the slope is:

m=\frac{100}{0.01}=10000

Now, calculating the coefficient b (y-intercept), we have:

\begin{gathered} (0.01,100)\colon \\ 100=0.01\cdot10000+b \\ 100=100+b \\ b=0 \end{gathered}

So the equation is:

y=10000x

d.

The maximum value of stress is 560, and occurs at strain = 0.07.
