A population of 55 foxes in a wildlife preserve doubles in size every 14 years. The function y equals 55 times 2 Superscript x , where x is the number of 14-year periods, models the population growth. How many foxes will there be after 28 years?
Answers
[tex]y=55*2^2=55*4=220[/tex]
There will be 220 foxes after 28 years.
Final answer:
To find the fox population after 28 years, we use the function y = 55 × 2^x, with x = 2 because 28 years is two 14-year periods. After calculating 2^2 and multiplying by 55, we find that there will be 220 foxes.
Explanation:
To calculate the number of foxes in a wildlife preserve after 28 years, given that the population doubles every 14 years, we start with the function y = 55 × 2^x, where x represents the number of 14-year periods.
Since 28 years is equivalent to 2 periods of 14 years, we will substitute x with 2:
Write down the equation substituting x with 2: y = 55 × 2^2.Calculate the exponent: 2^2 = 4.Multiply the base population by 4: 55 × 4 = 220.Therefore, after 28 years, there will be 220 foxes in the wildlife preserve.

Kelly is hanging shelves in her closet. She can buy shelves for $1.25 a foot. Kelly buys one 5-foot shelf and a shelf that measures 24 inches. The rest of her materials cost $90. How much change will she get it she pays with $100?
Answers
There are 12 inches in a foot.
Kelly buys two shelves that measure 7 feet altogether, and the cost of each foot is $1.25.
Multiply the number of feet by the cost per foot.
7 × 1.25 = 8.75
Add this to the cost of the rest of her items.
90 + 8.75 = 98.75
Finally, subtract this from the $100 Kelly will use to pay.
100 - 98.75 = 1.25
ANSWER: Kelly will receive $1.25 change after her payment.

Answer:
A. X < 3.
Step-by-step explanation:
We have the equation, [tex]3 + \frac{x-2}{x-3} \leq 4[/tex]
Adding -4 on both sides, we get,
[tex]\frac{x-2}{x-3} -1 \leq 0[/tex]
i.e. [tex]\frac{x-2-x+3}{x-3} \leq 0[/tex]
i.e. [tex]\frac{1}{x-3} \leq 0[/tex]
So, we have the inequality [tex]\frac{1}{x-3} \leq 0[/tex].
Its critical points are given by x-3 = 0 which implies x = 3.
Now, we will find the region among the two [tex]( - \infty , 3 )[/tex] and [tex]( 3 , \infty )[/tex] that satisfies the inequality [tex]\frac{x-2}{x-3} -1 \leq 0[/tex]
Substitute x = 2 in the above inequality, we get -1 < 0, which is true. Again, substitute x=4 gives 1 < 0, which is false.
As x=4 lie in the region [tex]( 3 , \infty )[/tex] , it cannot be the solution of the given inequality.
So, the solution of the given inequality is the region [tex]( - \infty , 3 )[/tex] .i.e. x < 3.

In a hockey club there are 5% more boys than there are girls. If there is a total of
246 members in the club, what is the number of boys and the number of girls?
HOW WOULD I WORK THIS OUT
Answers
For an instance, pb stands for percentage of boys, and pg stands for percentage of girls.
pb + pg = 100%
There are 5% more boys, pb = pg + 5%
Input to the previous equation to find the percentage of the girls
pb + pg = 100%
pg + 5% + pg = 100%
2pg + 5% = 100%
2pg = 100% - 5%
2pg = 95%
--------------- divide each side by 2
pg = 47.5%
Substitute the percentage of girls to either equations to find the percentage of the boys
pb = pg + 5%
pb = 47.5% + 5%
pb = 52.5%
Find the number of the boys and the girls
The boys
b = pb × total members
b = 52.5% × 246
b = 0.525 × 246
b = 129.15
Because the number of people couldn't be a fraction, round to the nearest whole number
b = 129
The girls
g = total - b
g = 246 - 129
g = 117
There are 129 of boys, and 117 of girls
The number of boys and the number of girls are 126 and 120 respectively.
What is percentage?A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.
Given that, there are 5% more boys than there are girls, there is a total of
246 members in the club,
We need to find the number of boys and the number of girls,
Here we will use the concept of percentage as well as equation solving,
Let the number of girls be x, so, the number of boys = 105% of x = 1.05x
According to the question,
x+1.05x = 246
2.05 x = 246
x = 120
1.05x = 126
Hence, the number of boys and the number of girls are 126 and 120 respectively.

2040+612=2652
so third one is true
Answer:
Option (c) is correct.
He pays $ 2652.
Step-by-step explanation:
Given : Nial is signing a lease for an apartment that rents for $1020/month.
We have to find the amount he pay to move in if he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent.
Since, given he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent.
Given monthly rent is $ 1020
That is 60% of his monthly rent = [tex]\frac{60}{100}\times 1020=612[/tex]
Thus, total amount he needs to pay is first month rent + last month rent + 60% of his monthly rent.
That is 1020 + 1020 + 612 = 2652.
Thus, He pays $ 2652.
i need to know the equations

2l +3t +3b = 156 . . . . . . . 156 meals per day are supplied
l +t = 3b . . . . . . . . . . . . . . there are 3 times as many great cats as bears
l +t +b = 68 . . . . . . . . . . . there are a total of 68 animals
_____
The last 2 equations tell you
.. 4b = 68
.. b = 17
Subtracting 3 times the last equation from the first gives
.. -l = -48
There are 48 lions, 3 tigers, and 17 bears.
Let T = number of tigers
Let B = number of bears
If one lion eats 2 meals per day, then L number of lions eat 2L meals per day.
Tigers eat 3T meals per day, and bears eat 3B meals per day.
In one day, all animals combined ate 156 meals.
That gives us our first equation.
2L + 3T + 3B = 156
The lions and tigers are considered great cats. The bears are not cats.
There are 3 times as many great cats as bears.
This gives us our second equation.
L + T = 3B
In all there are 68 animals in the zoo.
From here we get our third equation.
L + T + B = 68
Our system of equations is:
2L + 3T + 3B = 156
L + T = 3B
L + T + B = 68
Now we solve the system of equations.
Subtract the second equation from the third equation.
B = -3B + 68
4B = 68
B = 17
Substitute B = 17 into the first and second equations.
2L + 3T + 3B = 156
2L + 3T + 3(17) = 156
2L + 3T + 51 = 156
2L + 3T = 105 New Equation A
L + T = 3B
L + T = 3(17)
L + T = 51 Equation B
Equations A and B have only two variables, so we can solve them as a system of two equations in two unknowns.
2L + 3T = 105
L + T = 51
Rewrite equation A. Multiply Equation B by -2 and write underneath Equation A. Then add the equations.
2L + 3T = 105
+ -2L - 2T = -102
-------------------------
T = 3
Now use B = 17 and T = 3 in the original third equation to solve for L.
L + T + B = 68
L + 3 + 17 = 68
L + 20 = 68
L = 48
Answer: There are 48 lions, 3 tigers, and 17 bears
Check:
"Lions eat 2 meals per day, tigers and bears eat 3 meals each per day."
Number of meals:
2 * 48 + 3 * 3 + 3 * 17 = 96 + 9 + 51 = 156
"There are 3 times as many great cats in the zoo as bears."
48 + 3 = 51, and 51 is 3 times 17
"There are 68 animals in the zoo."
48 + 3 + 17 = 68
All statements are satisfied by our solution, so the answer above is correct.
My jar has 25 dimes and some quarters, nickels, and pennies. The number of quarters plus dimes equals the number of pennies. I have 4 nickels for every dime and 2 pennies for every nickel. How many quarters are there? A. 175 B. 150 C. 125 D. 75
Answers
q = quarters
p = pennies
n = nickels
1. q + n = p
2. 4n = 1 d
3. 2p = 1n
1 d = 4n
25 d = x
x = 4 * 25 = 100 nickels
1 n = 2 p
100 n = x p
100 n = 200 p
q + n = p
There are 100 nickels. there are 200 pennies
q + 100 = 200
q = 200 - 100
q = 100
Answer
There are 100 quarters,<<<<======
Answer:
Quarters = 175
Step-by-step explanation:
Let the number of dimes in the jar = 25
number of Nickels = n
number of quarters = q
number of pennies = p
Now we will form the equation
Number of quarters plus dimes equal the number of pennies.
q + 25 = p --------(1)
You have 4 nickles for every dime
n = 4d
n = 4 × 25 = 100
and you have 2 pennies for every nickels
p = 2n
p = 2 × 100 = 200
Now we replace p = 200 in equation (1)
q + 25 = 200
q = 200 - 25
q = 175
Option A. 175 will be the answer.
