The New Jersey Division of Fish and Wildlife keeps track of the beaver population in the Raritan River. They tagged 42 beavers and released them. A week later, they captured 54 beavers, including 14 tagged beavers. What is a good estimate of the beaver population in the Raritan River? There are approximately beavers in the Raritan River.
Answer:ratio is 14:54 = 42:B. Beavers = 162
Step-by-step explanation:
The ratio demonstrates how often one number is multiplied by another.
The approximate number of beavers exists 162.
What is meant by ratio?The ratio demonstrates how often one number is multiplied by another. When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage.
The relationship or comparison between two numbers in the same unit to determine how much larger one number is than the other is known as a ratio.
The 42 beavers were tagged and released by the New Jersey Division of Fish and Wildlife, which monitors the beaver population in the Raritan River. After a week, they had captured 54 beavers, 14 of which were marked. There are 54 Beavers in all, and 14 Beavers have tags.
Let the ratio be 14 : 54.
As 42 tagged beavers were released.
simplifying the above equation, we get
14 × 3 : 54 × 3
= 42 : 162
Therefore, the approximate number of beavers exists 162.

what is 2,340 divided by 36
Answer:
65.
Step-by-step explanation:
You could honestly just use a calculator for this, but okay.
The total weight of a rock depends on its size and is proportional to its density. In this context, density is the weight per cubic inch. Let w denote the weight of the rock in pounds, s the size of the rock in cubic inches, and d the density of the rock in pounds per cubic inch. If a 48-cubic-inch rock weighs w pounds, write an equation that shows the proportional relation.
Answer:
[tex]d = \frac{w}{48}[/tex]
If [tex]\frac{1}{48} \\[/tex] is constant, say k
Then,
[tex]d = kw[/tex]
∴ d ∝ w
Hence, weight is proportional to the density
Step-by-step explanation:
From the question,
Let w denote the weight of the rock in pounds
s denote the size of the rock in cubic inches and
d denote the density of the rock in pounds per cubic inch.
First, we will write the equation connecting w, s, and d.
We get
[tex]density (pounds/inch^{3} ) = \frac{weight(pounds)}{size (inch^{3}) }[/tex]
That is,
[tex]d = \frac{w}{s}[/tex]
Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write
[tex]d = \frac{w}{48}[/tex]
If [tex]\frac{1}{48} \\[/tex] is constant, say k
Then,
[tex]d = kw[/tex]
∴ d ∝ w
Hence, density is proportional to the weight OR weight is proportional to the density
Ben drank 1/5 pitcher of lemonade. Tonya drank 1/2 of the lemonade. How much lemonade did they drink together?
Answer:
7/10ths of the picture has been digested.
Step-by-step explanation:
Let's divide this into tenths.
One fifth out of ten is equal to two, since 10/5 = 2. A half of ten is five, because 10/2 = 5. Adding five and two together gives us 7/10ths, which can not be reduced to a smaller amount.
Given the function f(x) = -5|x + 1|
+ 3, for what values of x is f(x) = -12?
Answer:
2 and -4
Step-by-step explanation:
-5|x + 1| + 3 = -12
-5|x + 1| = -15
|x + 1| = 3
x + 1 = 3 / x + 1 = -3
x₁ = 2 / x₂ = -4
Move the horizontal and vertical sliders some more to stretch the image of the triangle. As you move the
sliders, observe what happens to the interior angles of each triangle. Based on your observations, can you say
that stretches preserve angle measurements?
Answer:
No, stretches do not preserve angle measurements. A stretch in either the horizontal or the vertical direction changes the interior angles.

a man steals 500naira from a shop,then bought an items worth 200naira collect 300naira change.how much does the shop keeper lose?
Today, 8 friends went out for lunch. Their total bill was $43.53, including tax and gratuity. One of them ordered only soda and needed to pay only $1.74. The
other 7 friends ordered the same daily special. How much did each of the other friends need to pay?
Answer:
5.97
Step-by-step explanation:
If one of them only ordered soda which costs $1.74 then you do 43.53 - 1.74 =41.79. Then do 41.79 divided by the other 7 people. 41.79 divided by 7 gets you the answer $5.97

What are the minimum and maximum values of x, for which x3 + x2 – 6x ≥ 0? minimum = –3, maximum = 0 minimum = 0, maximum = 2 minimum = –3, no maximum minimum = 2, no maximum Please answer quickly
Answer: Option C.
Step-by-step explanation:
The given inequality is
[tex]x^3+x^2-6x\geq 0[/tex]
Taking x common, we get
[tex]x(x^2+x-6)\geq 0[/tex]
Splitting the middle term, we get
[tex]x(x^2+3x-2x-6)\geq 0[/tex]
[tex]x(x(x+3)-2(x+3))\geq 0[/tex]
[tex]x(x+3)(x-2)\geq 0[/tex]
Related equation is
[tex]x(x+3)(x-2)=0[/tex]
[tex]x=-3,0,2[/tex]
These three points divide the number line in 4 parts.
Interval Sign of [tex]x(x+3)(x-2)\geq 0[/tex] Statement
(-∞,-3) [tex](-)(-)(-)=(-)[/tex] False
(-3,0) [tex](-)(+)(-)=(+)[/tex] True
(0,2) [tex](+)(+)(-)=(-)[/tex] False
(2,∞) [tex](+)(+)(+)=(+)[/tex] True
So, the solution set is (-3,0) ∪ (2,∞).
Thus, minimum value is –3 and no maximum value.
Therefore, the correct option is C.
Answer:
minimum = –3, no maximum

Subtract -3 – (-7). who will be first to answer....
Answer:
Its 4
Step-by-step explanation:
Because it is
Answer:
4
Step-by-step explanation:
1) First, distribute the negative sign to the -7. Because of this, the -7 will become a positive 7.
Equation: -3+7
2) Next, whenever there are two different signs, we are supposed to subtract the bigger number (7) with the smaller number (3).
Equation: 7-3=4
3) Finally, assign the greatest number sign. in this case, 7 is the greater number, and the 7 is a positive number; therefore, it will be a positive 4.

I need to find the measurement of AEB please help me!
Triangle BEC is an isosceles triangle.
The angles opposite the congruent sides are equal
x = measure of missing angle
180 = 54 + 2x
Subtract 54 from both sides
126 = 2x
Divide both sides by 2
63 = x
angle EBC and angle C = 63 degrees
Angle EBC and angle EBA are supplementary.
This means they add up to 180 degrees
180 = 63 + EBA
Subtract 63 from both sides
117 = EBA
the measure of a triangle = 180
Therefore,
The measure of angle AEB = 180 - (40 + 117) = 23 degrees
