Prime numbers are numbers that are greater than one and its only factors, the things that multiply to equal it, are one and itself. An example is the number seven the only numbers multiplied together that can equal 7 are 7x1.

Use the graph to answer the question. About how many more website hits were there on Tuesday than on Monday? A. 700 B. 400 C. 60

nadezda [96]

In this graph, each day has its own graph, starting at the bottom with Monday, to the top at Sunday. To know how many hits each day had, go to the end of the graph, and the closest number at the bottom is how many hits there were. This graph states that there were around 1900 hits on Tuesday, and 1300 on Monday. To get the answer we then take the difference, getting 600.

Answer:

19 or c

Step-by-step explanation:

Hi I just took the test as you can see on the chart by the x axis it goes from 10 to 11 and on the y axis it goes from 27 to a so really it’s just simple subtraction

What is 1 2/5 × 2<br>what is 1/4 × 1

Mrrafil [7]

Answer:

$1).$ $2\frac{4}{5}$

$2).$ $\frac{1}{4}$

Step-by-step explanation:

$1).$ $1\frac{2}{5}*2$

Convert mixed number to improper fraction: $a\frac{b}{c} =\frac{a*c+b}{c}$

$1\frac{x2}{5} =\frac{1*5+2}{5} =\frac{7}{5}$

$\frac{7}{5} *2$

Apply the fraction rule: $\frac{a}{b}*c =\frac{a*c}{b}$

$\frac{7}{5} *2=\frac{7*2}{5}$

$=\frac{7*2}{5}$

Multiply the numbers: $7*2=14$

$=\frac{14}{5}$

Convert improper fractions to mixed numbers: $\frac{14}{5}$

$\frac{14}{5}$

Write the problem in long division format:

$\begin{matrix}5\overline{|\smallspace14}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Divide $14$ by $5$ to get $2$

Multiply the quotient digit $(2)$ by the divisor $5$

$\begin{matrix}\space\space\space\space\space\space\emptyspace2\space\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace14}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace1\emptyspace0}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Subtract $10$ from $14$

The solution for long division of $\frac{14}{5}$ is $2$ with a remainder of $4$

$2\quad \mathrm{Remainder}\quad \:4$

Convert to mixed number: $Quotient\frac{Remainder}{Divisor}$

$\frac{14}{5} =2\frac{4}{5}$

$=2\frac{4}{5}$

$2\frac{4}{5}$

Convert $\frac{4}{5}$ to decimal using long division

$\frac{4}{5}$

Divide $4$ by $5$ to get $0$

Multiply the quotient digit $(0)$ by the divisor $5$

$\begin{matrix}\space\space\space\space\emptyspace0\space\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace4}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace0}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Subtract $0$ from $4$

Add a decimal place and a zero to the dividend

Bring down the zero from the dividend

$\begin{matrix}\space\space\space\space\emptyspace0.\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace4.0}\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace0}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\emptyspace4\emptyspace0\space\space\space\space\space\space\space\space\space\space\end{matrix}$
