Mathematics

Answer:

no. it isn't necessary.

Step-by-step explanation:

there are some cases where adding two repeating decimals results in a sum which does not have a repeating decimal. For example,  

1 over 3

+

2 over 3  

=

3 over 3  

=1

. Thus, the sum of two repeating decimals is not always a repeating decimal.

A small company employs 3 men and 5 women. If a team of 4 employees is to be randomly selected to organize the company retreat,
Paraphin [41]

Answer:

3/7.

Step-by-step explanation:

The total number of ways to pick 4 out of 8 = 8C4

= 8!/ 4!4!

= 70 ways.

The number of ways when  2 are women =  5C2 * 3

= 10 * 3

= 30.

So the required probability = 30/70

= 3/7.

Answer:

5. Obtuse angle and angle measurement- 130

6. Obtuse angle and angle measurement- 110

Step-by-step explanation:

If you look at the protractor you can see the numbers and if its right of the 90 degrees than its acute if its left of the 90 degrees than its obtuse. If its 90 degrees exactly then its a right angle. And you look at the numbers below the line to find the measurement and look where the line is exactly, then thats your measurement. Hope this helped!

18. What is the y-intercept of the line that passes<br> through the points (1, 1) and (5, 13)?
TEA [102]

Answer:

-2

(The coordinate point is (0,-2))

Step-by-step explanation:

First, make an equation of the line.

Start off with finding the slope:

Slope = (13-1)/(5-1) = 12/4 = 3

Then solve for the y-intercept though substitution and simplification:

y=mx+b --> 1=3(1)+b --> 1=3+b --> b= -2

So the answer is -2.

1700÷40= 42.5 

step one: you divide 40 into 1700
step two: you find the closest number that goes into 1700 which is 4 so 40×4= 160
step three: then you subtract 1700 from 160 and you'll get 100
step four: then you'll find the closest number that goes into a 100 and that will be 2 so 40×2=80
step 5: you'll then subtract 100 from 80 and you'll get 20 
step 6: you when then add a decimal and add an extra 0 to 1700 so you will now have 17000 you will bring down the 0 to make 20 into 200 and you will find the closest number that will go into 200 which will be 5 cause 40×5= 200 so you're answer will be 42.5units
