Mathematics
1 answer:
hodyreva [135]3 years ago

Answer:

C, (x = 100, y = 10)

Step-by-step explanation:

hi again,

(2x - 70) = (x + 30), by the Alternate Exterior Angles

x - 70 = 30

<em>x = 100</em>

<em />

(2x - 70) + 5y = 180, by the Linear Pair Theorem

2(100) - 70 + 5y = 180

200 - 70 + 5y = 180

130 + 5y = 180

5y = 50

<em>y = 10</em>

Brut [27]

Answer:Just calculate this:

A) 2(3m + 5) = 6m + 10 - incorrect

B) -2(5 - 3m) = -10 + 6m - could be correct

C) 2(3m - 10) = 63 - 20 - incorrect

So the correct answer has to be B: -10 + 6m is the same as 6m - 10 hopes this help

A patient is to receive 1.08 L of fluid over 3 hours through an IV drip. There are 16 drops/ml. How many drops per minute are re
KATRIN_1 [288]
How many drops per minute?
There are 16 drops per ML.

1000 ML  =    1 L.
1L  =  1000 ML

Therefore 1.08 L  =  1.08 * 1000 = 1080 ML

16 drops  per ML means I ML has 16 drops.

Therefore 1080 ML has:    (1080 * 16) drops.

Number of drops per min:
Since the entire process took 3 hours =  3 * 60 minutes = 180 minutes.

Therefore Number of drops per minute  = Number of Drops / Time in minutes
                                                        = (1080 * 16) /(180)
                                                        = 96 drops per minute.

A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, gi
defon

Answer:

An ordered pair is a set of inputs and outputs and represents a relationship between the two values. A relation is a set of inputs and outputs, and a function is a relation with one output for each input.

h

here is a exstended explantion:

A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to.

For example, consider the following sets X and Y. I'll give you a relation between them that is not a function, and one that is.

   X = { 1, 2, 3 }

   Y = { a , b , c, d }

   Relation from X to Y (i.e., in XxY ) : { (1,a) , (2, b) , (2, c) , (3, d) }

This relation is not a function from X to Y because the element 2 in X is related to two different elements, b and c. (Note, if you transpose the ordered pairs you <i>would</i> have a function from Y to X - can you see WHY?)

   Relation from X to Y that is a function: { (1,d) , (2,d) , (3, a) }

This is a function since each element from X is related to only one element in Y. Note that it is okay for two different elements in X to be related to the same element in Y. It's still a function, it's just not a one-to-one function.
