A farmer wanted to estimate how many moles were living on his property, so he marked 24 of them with tags. A few weeks later, the farmer drove around his property and noticed 18 tagged moles out of the 330 moles he counted. To the nearest whole number, what is the best estimate for the mole population?
Answer:
The answer is 70 moles
Step-by-step explanation:
For the farmer,
Total no of Moles = 330
No of marked moles with tags = 24
No of unmarked moles = 330 - 24 = 306
Few weeks later,
No of tagged moles found = 18
No of tagged moles not found,
= marked moles with tags - tagged moles found
= 24 - 18 = 6
Therefore, if for every 24 tagged moles, there are 6 moles found,
288 tagged moles = 24 X 12 (lots) = 288
For moles found = 6 X 12 (lots) = 72
To the nearest whole number,
The best estimate for the mole population would be 70 moles

Misha solves the following system of equations using the substitution method.
y=5−2x
3x−y=15
What is the single-variable equation she solves after substituting?
A. 3(5+x)=5−2x
B. 15+3x=5−2x
C. 3x−(5−2x)=15
D. 3x−5−2x=15
Answer:
C
Step-by-step explanation:
The single equation of the system of equation y=5−2x and 3x−y=15 by substitution will be 3x−(5−2x)=15 thus option (C) will be correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given system of equations,
y = 5 − 2x
3x − y = 15
Substitute y = 5 - 2x into 3x − y = 15
3x - (5 - 2x) = 15
Hence "The single equation of the system of equation y=5−2x and 3x−y=15 by substitution will be 3x−(5−2x)=15".

find the compound interest on 30,000 for 2years at 7 percent per annum
Answer:
34347
Step-by-step explanation:
Use the formula s=p(1+r/k)^kt
p=30000
r=7% (interest)
k=1 (because of per annum)
t= 2 (years)
Hence: 30000(1+0.07/1)^1(2) = 34347

Chloe is deciding between two landscaping companies for her place of business. Company A charges $70 per hour and a $150 equipment fee. Company B charges $55 per hour and a $300 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation, in terms of t,t, and determine the number hours, t,t, that would make the cost of each company the same.
The equations are AA = 150 + 70t and BB = 300 + 55t.
It is 10 hours which make the cost of each company the same.
Given,
Company A:
Charge for an hour =$ 70
Equipment fee = $ 150
Charge for ' t ' hours = 70 x t = 70t
Total cost = Equipment fee + charge for t hours
AA = 150 + 70t
Company B:
Charge for an hour =$ 55
Equipment fee = $ 300
Charge for 't' hours = 55 x t = 55t
Total cost = Equipment fee + charge for t hours
BB = 300 + 55t
Now, we have to find
BB = AA
300 + 55t = 150 + 70t
300 – 150 = 70t – 55t
150 = 15t
t = 150 / 15
t = 10
That is,
The equations are AA = 150 + 70t and BB = 300 + 55t.
It is 10 hours which make the cost of each company the same.

Answer:
When you find the volume of a triangle, remember to do this:
Step-by-step explanation:
Multiply the base times the height, then divide by two.
:)
The mistake is in the second triangle and is noticeable at first because the length of the leg is longer than the length of the hypotenuse.
Since this is a 30 60 90 triangle, you can use the properties that apply to them. I'm assuming that the leg with the length of 62ft is the given side. Using the rules, we know that x/2 is 62 (since the properties of a 30 60 90 triangle state that the shortest side is x/2). In order to find the hypotenuse (which is x), we can multiply both sides of the equation x/2 = 62 to get x = 124. To find the second leg, we need to use sqrt(3)*x/2, which when you plug in 124, gives 107.39. Andrea just switched the lengths of the second leg and the hypotenuse on accident.
