Joe is a scientist who works with the Department of Agriculture. In order to ensure a good harvest, Joe keeps track of various local beetle populations. He catches 590 beetles, marks them, and releases them. Then later, he catches 2,000 beetles, 59 of which are marked. To the nearest whole number, what is the best estimate for the beetle population?
( 11 points if solved)
Will give brainliest, if the answer is correct OR well explaining explanation ( Either Both)
Answer:
There are 20,000 Beatles in the total population
Step-by-step explanation:
59 Beatles out of the 2,000 are marked (2.95% or 59/2000)
-----------------------------------------
1 / 0.0295 = 33.8983051
That means that the total population is 33.89 times larger than the 590 marked beatles.
33.8983051 x 590 = 20,0000 Beatles total
Answer:
Approximately 20,000 beetles
Step-by-step explanation:
The answer is approximately 20,000 beetles because Joe found 590 beetles and marked them. When he found the other 2,000 beetles, 59 of them were marked. 59 is 10% of 590. Since Joe found 2,000 beetles that must be 10% of some number. To find that number, you must multiply 2,000 by 10. So 2,000 x 10 is 20,000, so there is approximately 20,000 beetles

A small, test batch of lemonade used 14 cup of sugar added to 1 cup of water and 14 cup of lemon juice. After confirming it tasted good, a larger batch is going to be made with the same ratios using 10 cups of water.
Answer:
whats the question here?
Step-by-step explanation:
Answer:
Hi there!
In order to answer your question, you'll need to use the cross product method:
1 cup water → 1/4 cup sugar
10 cups water → X cup sugar
((1/4) × 10) ÷ 1 = X cups sugar
2.5 ÷ 1 = X cups sugar
2.5 = X cups sugar
Your answer is : Using 10 cups of water, you should add 2 and a half cups of sugar so that the large batch tastes the same as the test batch.
There you go! I really hope this helped, if there's anything just let me know! :)

If 3y + 3 = y + 7 is the same as y + y +y + 1 + 1 + 1 = y + 1 + 1 + 1 + 1+ 1 + 1 + 1, then how can we isolate 'y' without disrupting the balance?
Answer: The expanded form isn't required. Just make sure that it's possible to send the variable you are solving for to one side, and then solve.
Step-by-step explanation:
combine like terms:
3y-y = 7-3
2y = 4
y = 2
Alonzo will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an additional 0.10 per mile driven. The second plan has no initial fee but costs 0.60 per mile driven. How many miles would Alonzo need to drive for the two plans to cost the same?
Answer:
for plan B if he rides for 100 miles he will pay 60$
for plan A if he rides for 100 miles he will pay 60$
Step-by-step explanation:
the reason is that B. 100x0.60=60
and A (100x0.10)+50=60
Answer:
100 miles
Step-by-step explanation:
If Alonzo drives 0 miles, then the first plan would cost him 50 dollars and the second plan would cost him nothing.
If Alonzo drives 10 miles, then the first plan would cost him 51 dollars and the second plan would cost him 6 dollars.
From these statements, we can observe that the second plan is increasing at a rate 6 times the first one and will overtake it at one point.
Our solution is the point of intersection between these two functions - where they cost the same.
To find this, equate
0.1x + 50 = 0.6x
where x is the number of miles Alonzo drives,
multiply the equation with 10 to get,
x + 500 = 6x
subtract x,
5x = 500
and divide 5,
x = 100.
So at 100 miles, both plan 1 and 2 will cost 60$. This is our answer. Good Luck!

Solve the inequality c – 5 ≥ 0.5 and graph the solutions.
Answer:
c ≥ 5.5
Step-by-step explanatation:
c - 5 ≥ 0.5
*Add 5 to the left and the right of the inequality symbol*
Which leaves you with, c ≥ 5.5
In this case, the 'c' is unknown when graphing because you don't know if it can be called x or y. So, you cannot plot this variable.
Max makes bread that calls for 7/8 cup of raisins per loaf. He has 5 1/4 cups of raisins. How many loaves of bread can he make?
The answer is 6 1/2 loaves. True or False?
Answer:
False.
Step-by-step explanation:
The answer is NOT 6 1/2 loaves it is 6 loaves.
Knowing that there Max has 5 1/4 cups of raisins and each loaf requires 7/8 cup of raisins, we would need to divide.
Let's turn the 5 1/4 into an improper fraction so when we divide the two fractions, it would be easier!
To turn 5 1/4 into an improper fraction we need to...
5 x 4 = 20
20 + 1
21/4
Now we divided 21/4 by 7/8.
When dividing fractions remember the rule: KEEP CHANGE FLIP!
We keep the first fraction...which is 21/4 in this case
Change the sign from division to multiplication
21/4 x 7/8
And flip 7/8 so it becomes 8/7
21/4 x 8/7
= 168/28
= 6 loaves
So, the answer is not 6 1/2 loaves (false!)
Answer:
False
Step-by-step explanation:
Given :
[tex]\frac{7}{8}[/tex] Cup of Raisin per loaf
Have [tex]5\frac{1}{4}[/tex] Cup of Raisin
Calculation steps:
[tex]\frac{21}{4}[/tex] ÷ [tex]\frac{7}{8}[/tex]
=
[tex]\frac{21}{4}[/tex] × [tex]\frac{8}{7}[/tex]
=
[tex]\frac{21 x 8}{4 x 7}[/tex]
=
[tex]\frac{168}{28}[/tex]
=
[tex]\frac{168 / 28}{28/28}[/tex]
= [tex]6[/tex]
Further explanation
For the problem:
21 /4 ÷7/ 8 = ?
Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:
21 /4÷7 /8 =21/ 4 ×8/ 7
Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
[tex]\frac{21x8}{4x7} =\frac{168}{28}[/tex]
The Greatest Common Factor (GCF) of 168 and 28 is 28. The result can be simplified by dividing both the numerator and denominator by 28.[tex]\frac{168}{28}=\frac{168/28}{28/28} =6[/tex]
Therefore the result is: 6
