Lake Alice is filled with alligators and turtles. The number of turtles is 16 less than 3 times the number of alligators in the lake. There are 200 reptiles total. Create the equation, then solve it. what does the answer mean in real world scenarios?
Answers
Answer:
187
Step-by-step explanation:
16 less than 3 times means 16-3.
so when 16-3=13, hence there is 200 reptiles total. so what we do is subract the 200 and the 13. 200-13=187
Suppose a certain breed of dog loses about 75 hairs per day. What integer represent this change in the amount of hair per week write a mathematical argument that can be used to defend your solution
Answers
Answer:
75 hairs/ day = 525 hairs / week
Step-by-step explanation:
so your base question for this is 75 hairs/ day =? h/ week. how? if the dog is losing 75 hairs per day, then you would do 75 x 7 becuase there are 7 days in a week. the answer to that would give you how many hairs the dog was losing per week. (see attached image for reference)

Answer:
B) 60%
Step-by-step explanation:
Percentage formula
\(\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100\)
To find what percent of 200 is 120, substitute the values into the percentage formula:
\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)
Therefore, 120 is 60% of 200.

Answers
Answer:
Step-by-step explanation:
Given:
Angular acceleration (α) = 1.2 rad/s^2
Radius (r) = 1.1 m
Substituting the values into the formula, we have:
Centripetal acceleration (a) = 1.1 m × 1.2 rad/s^2
Calculating the value:
a = 1.32 m/s^2
Therefore, the centripetal acceleration of the object is 1.32 m/s^2.

The base and height of a triangle are increased by 30% of their initial length. By what percentage does the area of the triangle increase?
Answers
Step-by-step explanation:
Area of a triangle is directly proportional to the base and height of the triangle.
Let B and H be the original base and height of the triangle respectively.
The new triangle has base 1.3B and height 1.3H
Area of original triangle : Area of new triangle
= 0.5BH : 0.5(1.3B)(1.3H)
= 0.5BH : 0.5(1.69BH)
= 1 : 1.69
Hence, the new triangle is 69% larger than the original triangle.

(i) Equation : y = 6.25x + 65
(ii) Price of each ticket : $6.25
(iii) Money originally in the box : $65
Explanation:
Here from table, identify the coordinates given.
Coordinates:
(7, 108.75)(13, 146.25)(18, 177.50)Find slope:
\(\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points\)
\(\rightarrow \sf slope \ (m) : \dfrac{146.25-108.75}{13-7} = 6.25\)
Slope is also the price of each ticket which is $6.25
Equation:
\(\sf y - y_1 = m(x - x_1)\)
\(\rightarrow \sf y - 108.75 = 6.25(x - 7)\)
\(\rightarrow \sf y - 108.75 = 6.25x - 43.75\)
\(\rightarrow \sf y = 6.25x - 43.75 + 108.75\)
\(\rightarrow \sf y = 6.25x +65\)
To find the amount of money in the box originally, insert x which represents number of tickets sold as 0.
Originally amount of money:
\(\rightarrow \sf y = 6.25(0) +65\)
\(\rightarrow \sf y = 65\)
Hence, there were $65 in the box before any tickets were sold.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Please see my Work, Attached.
Step-by-step explanation:
For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.
Directions: Follow the instructions for the following inequalities.
1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
3. -2 less than or equal to -2 Subtract 6 from both sides, then 8, and then 2
4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answers
Answer:
1. 504 < 1512
2. 12 > 0
3. -2 = -2
4. -1 < 2
Step-by-step explanation:
Given that both sides are being changed by the same amount and sign, the sign never changes. They always have the same value.
Please Help and Explain this like how do I calculate income tax and capital gain and investments
Answers
Answer: down below...
Step-by-step explanation:
Exercise 1:
Income = $83.465
Tax paid at 5.05% means, whatever your income is, you gotta pay 5.05% of it as a tax.
5.05% = \(\frac{5.05}{100}\)
\(\frac{5.05}{100}*$83.465\)
\(0.0505*$83.465\)
If you do the calculations it should give you a $4,214.9825 tax
"Income tax paid at 9.15%"
\(\frac{9.15}{100}*83.465\)
\(0.0915*83.465\)
The 9.15% tax = $7,637.0475
"Total income tax paid"
This will just be the sum of the two taxes.
$4,214.9825+$7,637.0475 = $11,852.03 (sum of taxes)
Exercise 2:
Purchase price = $347.000
Selling price = $863.000
As you can see, they purchased the property for $347.000 and sold it for $863.000 which made them a lot of money in profit :)
That's what the Difference is.
Difference = $863.000-$347.000
Difference = $516,000
I don't really understand what capital gains are, because I'm 13, but I suppose I gotta calculate 50% of the profit that the banker has made.
\(\frac{50}{100}*$516.000\)
\(\frac{5}{1}*$51.600\)
\(5*$51.600\)
"Capital gains" = $258,000
I don't really know if this is the correct answer for capital gains, but I am pretty sure I did well on the other ones.
Hope I helped you :] !
