Answer:
true
Step-by-step explanation:
$6.84 divided by 18= .38 which means 38 cents per pen
$8.40 divided by 30= .28 which means 28 cents per pen
so $8.40 for 30 pens is a better deal than 18 pens for $6.84 by ten cents.
we know that
using proportion
therefore
the answer is equal to
$45+$15.50= $60.50
$60.50-$32.75=$27.75
Answer:
Price and Demand
Step-by-step explanation:
We need to find a real-world relation in which the independent and dependent variables are not clear.
Let us consider, the price and demand relationship of a product.
In this relation, sometimes the demand of the product depends on its price and sometimes the price of the product varies according to its demand.
Thus, the independent and dependent variables changes according.
So, there is no clarity of the independent and dependent variables in the relation between the price and demand of a product.
If you consider humans, a single human is not capable of doing everything.
In Some ways he is dependent on other humans for different purposes.
But you can say that he or she is Independent , he or she has got his or her unique identity by saying he has got different features like body structure, appearance, Face, eyes etc... . He or She is different from others. So this way he is Independent,
But by considering man as Social animal , you can say that we humans are not independent but dependent on each other for survival or for our existence on this planet called earth.
→→A Single Human ⇒ Humans( there is no clear independent or dependent variable)
A. 180°+z−w
B. 180°–z−w
C. w−z
D. 180°+w−z
Answer:
A. 180°+z−w
Step-by-step explanation:
We know that x + w = 180 because they are same side exterior angles and a and b are parallel.
z=y because they are alternate interior angles and a and b are parallel.
x + w = 180
Solve for x by subtracting w from each side
x = 180-w
y =z
Lets find x+y
x+y
(180-w) +z
Rewriting
180+z-w
Answer:
A. 180º + z - w
Step-by-step explanation:
x + w = 180, because they are same side exterior angles, and are on opposite sides.
z = y, because if you move z down, then you will see that they overlap.
From x + w = 180, you can get x = 180 - w.
We are trying to find x + y in terms of w and z, so:
x = 180 - w
y = z
With that, you can assemble the expression, 180 - w + z.
If you re-arrange, you will get 180 + z - w.
Therefore, A is the answer.
