The standard form of the equation of a circumference is given by the following expression:
</span>

<span>
On the other hand,
the general form is given as follows:
</span>

<span>
In this way, we can order the mentioned equations as follows:
Equations in Standard Form: </span>
Equations in General Form:


So let's match each equation:
Then, its general form is:
<em><u>First. a) matches 5)
</u></em>

Then, its general form is:
<em><u>Second. b) matches 1)
</u></em>
Then, its general form is:
<em><u>Third. c) matches 3)</u></em>
Then, its general form is:
<em><u>Fourth. d) matches 6)</u></em>
The formula for density = number/ area
In this case number=20
area = 5m^2
Density = 20/5=4 mice per m^2
The right answer is <span>A. 4 per m2</span>

I'm going to just go by this because of research and you didn't show the 4 problems so if this fixes your question then there you go
Answer:
120 liters of 60% alcohol solution is needed
Step-by-step explanation:
Let's assume
x liters of 60% alcohol solution is added
so, we get solution as


we are given
40 liters of a 20% alcohol solution is



so, total alcohol solution is

now, we can find total solutions
total solutions is

now, it is making 50% solution
so, we get

now, we can solve for x




So,
120 liters of 60% alcohol solution is needed
Answer:
C
Step-by-step explanation:
Here is the complete question
ack wants to fined out which can pineapples is the best buy. He has a choice of four different -sized cans. Which can has the lowest unit price per ounce?
A. 8 ounce for $ 1.44
B. 6 ounce for $ 1. 14
C. 18 ounce for $ 2.88
D. 10 ounce for $ 1.62
unit price = price / total ounces
$1.44 / 8 = $0.18
$1.14 / 6 = $0.19
$2.88 / 18 = $0.16
$1.62 / 10 = 0.162
the lowest is 18 ounce for $ 2.88
