Answer:

Step-by-step explanation:

I'm still not exactly sure what the question really is, but the level suggests that it is

y = (6/7)x + 5

Any line that is parallel to this line has a slope of 6/7

Any line that is perpendicular to this line is a little more complicated.

slope of given line * slope of perpendicular line = - 1

6/7 * perpendicular slope = - 1  

Multiply by 7

6*perpendicular slope = - 7

Divide by 6

perpendicular slope = - 7/6

How many multiples of 4 are there in {n; 37< n <1001}?
s2008m [1.1K]
Let's begin by listing the first few multiples of 4:  4, 8, 12, 16, 20, 24, 28, 32, 36, 38, 40, 44.  So, between 1 and 37 there are 9 such multiples:  {4, 8, 12, 16, 20, 24, 28, 32, 36}.  Note that 4 divided into 36 is 9.

Let's experiment by modifying the given problem a bit, for the purpose of discovering any pattern that may exist:

<span>How many multiples of 4 are there in {n; 37< n <101}?  We could list and then count them:  {40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100}; there are 16 such multiples in that particular interval.  Try subtracting 40 from 100; we get 60.  Dividing 60 by 4, we get 15, which is 1 less than 16.  So it seems that if we subtract 40 from 1000 and divide the result by 4, and then add 1, we get the number of multiples of 4 between 37 and 1001:

1000
   -40
-------
 960

Dividing this by 4, we get 240.  Adding 1, we get 241.

Finally, subtract 9 from 241:  We get 232.

There are 232 multiples of 4 between 37 and 1001.

Can you think of a more straightforward method of determining this number? </span>

Your recipe for lemonade calls for 2 liters, 5 deciliters of lemon juice mixed with 3 liters, 2 deciliters of water. How much le
natima [27]

Answer:

5.7 liters

Step-by-step explanation:

The sum of 2 liters, 5 deciliters of lemon juice and 3 liters, 2 deciliters of water will be given as

2+3=5 liters

5+2=7 deciliters

Therefore, we get 5 liters, 7 deciliters of lemonade

Conversion

10 deciliters equal to 1 liter hence 7 deciliter will be 7/10=0.7 liters

5+0.7=5.7 liters
