Answer:
See explanation.
Step-by-step explanation:
To find the area of a parallogram, do A=Bh where a is the area, b is the base, and h is the height.
In this case, b is 9 cm while h is 6 cm. Do A=Bh by multiplying 9 cm by 6 cm. This will give us 54 cm².
The measurement we didn't use is the measure of the diagonal parts of the quadrilateral which, in this case, was 7.5 cm.
Answer:
C. 1 and 3
Step-by-step explanation:
You are right, now here's why.
You are looking for two equations that have the same constant of proportionality. That means they behave the same, that if you enter a X value in one, you'll get the same effect as if you enter it in another.
If you look at all four equations, you'll see that 1 and 3 are essentially the same thing, just that the first one is simplified (4y = 3x) while the other isn't (8y = 6x). But for each time you enter a X value, the Y value will be 33% (1/3) bigger.

Answer:
p : q = 3 : 2
Step-by-step explanation:
You are given sufficient information to write two relations involving p and q. We presume these will be sufficient to find an answer to the question. We will be able to find p and q. Then we can find their ratio, as the problem asks.
(p-15)/(q-15) = 2/1
(p+30)/(q+30) = 5/4
__
From the first equation, we get ...
p -15 = 2(q -15)
p = 2q -15 . . . . . . . add 15, simplify
From the second equation, we get ...
4(p +30) = 5(q +30)
4p + 120 = 5q + 150
4p = 5q + 30
Using the first equation to substitute for p, we have ...
4(2q -15) = 5q +30
8q -60 = 5q +30 . . . eliminate parentheses
3q = 90 . . . . . . . . . . . add 60-5q to both sides
q = 30 . . . . . . . . . . . . divide by 3
p = 2q -15 = 2(30) -15 = 45
Then the desired ratio is ...
p : q = 45 : 30
p : q = 3 : 2
