Look at picture and solve

Aleks04 [339]

Step-by-step explanation:

As we can see, the line on the bottom is a perfectly straight 180º line, so the two angles, a and 50º are supplementary angles. Remember: Supplementary angles = 180º, and complementary angles = 90º.

Since this is a 180º line, all we have to do is to subtract 50 from 180 to get our angle a.

180-50 = 130º

Our answer: a = 130º

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

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

Divide $40$ by $5$ to get $8$

$\frac{40}{5} =8$

The solution for long division of $\frac{4}{5}$ is $0.8$

$=2+0.8$

Add $2+0.8=2.8$

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

Multiply $\frac{1}{4} *1=\frac{1}{4}$

$=\frac{1}{4}$

Anything multiplied by $1$ is the same number.

Divide the the numbers $\frac{1}{4}$ to get decimal form

Divide $1$ by $4$

$\frac{1}{4} =0.25$

$=0.25$

Can someone please give me the (Answers) to this? ... please ...

seropon [69]

Answer:

For A1-4 I am pretty sure the answers are: Question 1.) 3/1 (or 3) Question 2.) -6/6 (also can be written as -1) Question 3.) 9/5 and Question 4.) -4/3

Step-by-step explanation:

For Question 1 you just rise 3 and run 1 which gets you 3/1

For Question 2, to get from coordinate 2 to 8 you add 6, and to get from coordinate -10 to -16 you subtract 6. This leaves you with -6/6 (or -1)

For Question 3, the slope is written within the equation (y=9/5x-5) the 9/5 is the slope.

For Question 4, you take 4x+3y=6 and turn it into y=mx+b form, to do so you subtract 4x on both sides leaving you with 3y=-4x+6. Then you divide 3 on both sides, y=-4x/3 + 6/3. Then the result would be y=-4/3x+2 which means that the slope is -4/3.

I am not sure if these are all correct, but i hope it helps! :)

Plz help me in this homework

evablogger [386]

Step-by-step explanation:

You basically have to divide your number from a prime factor until your result is 1

For example

you divide it from the lowest prime number possible, for in this case, 2

12/2 = 6 and you can set aside 2 for now

You do the same thing and you divide it by 2

6/2 = 3 and set aside 2

Now 3 isn't divisible by 2 so you'll find another number, for in this case 3

3/3 = 1

your set side numbers are now 2,2,3

so you'll find out 12 = 2x2x3 as a product of it's prime factors

how ever you cant divide it by 4 or 6 since they aren't prime factors as they are divisible by other numbers
