30% of the animals in a wildlife park are lemurs, 40% are ring tailed lemurs. What percentage of the animals in the wildlife park are ring tailed lemurs?
12% of total animals are ring-tailed lemurs.
What is percentage?A percentage is a fraction of an amount expressed as a particular number of hundredths of that amount.
Given that, 30% of the animals in a wildlife park are lemurs, 40% are ring-tailed lemurs.
Let total animals be 100.
30% of 100 = 30
40% of 30 = 12
12/100*100 = 12%
Hence, 12% of total animals are ring-tailed lemurs.

An account earning interest at a rate of 4% compounded monthly has a principal of $ 500,000 . If no more deposits or withdrawals are made , how much money will be in the account after five years?
Answer:
$610,498.30
Step-by-step explanation:
P = C (1 + r/n)^nt
4% = 0.04
P = 500 000(1+0.04/12)^(12*5)
P = 500 000 (1.003333)^60
P = 500 000 (1.220997)
P = $610 498.296971
Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared.
q^2+5/6q
The perfect square trinomial and binomial of the expression [tex]q^{2}[/tex] + [tex]\frac{5}{6}q[/tex] are [tex]q^{2}[/tex] + [tex]\frac{5}{6}q[/tex] + [tex]\frac{25}{144}[/tex] and [tex](q + \frac{5}{12}) ^{2}[/tex]
What is a perfect square expression?Perfect squares are numbers or expressions that are the product of a number or expression multiplied to itself. 7 times 7 is 49, so 49 is a perfect square. x squared times x squared equals x to the fourth, so x to the fourth is a perfect square.
[tex]q^{2}[/tex] + [tex]\frac{5}{6}q[/tex] expression can be made into a perfect square by adding the square of half the coefficient of q
coefficient of q = [tex]\frac{5}{6}[/tex]
Half of [tex]\frac{5}{6}[/tex] = [tex]\frac{5}{12}[/tex]
square [tex]\frac{5}{12}[/tex] we have [tex](\frac{5}{12}) ^{2}[/tex] which becomes [tex]\frac{25}{144}[/tex]
so the perfect square trinomial = [tex]q^{2}[/tex] + [tex]\frac{5}{6}q[/tex] + [tex]\frac{25}{144}[/tex]
the binomial is [tex](q + \frac{5}{12}) ^{2}[/tex]

A) y = -7x + 4
OB) y = -7/4x
OC) 4x + 7y= 0
D) y = 4x - 7
Required equation of line in slope intercept form
y = 4x - 7
What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = [tex]tan \theta[/tex]
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
Slope of the line = 4
y - intercept of the line = -7
The line passes through (0. -7)
Equation of the required line
y - (-7) = 4(x - 0)
y + 7 = 4x
y = 4x - 7

6. Hannah likes to spend her free time hanging out at the airport. She likes to run on the walkways. While running with the walkway, she can cover 48 feet in 3 seconds. While running against the walkway, she can cover 24 feet in 2 seconds. Find Hannah's rate (in feet per second) if the walkway stopped moving.
Answer:
4) Melody is 9 and her sister is 24
5) The numbers are 3 and 9
6) 14 feet per second
Step-by-step explanation:
Questions 4
There is a lot going on here. This is probably hard to follow. If it is, it is me and not you.
Let m = Melody and s = sister
m - 4 = 1/4(s-4) m + 6 = 1/2(s + 6) Clear the fractions
4m - 16 = s -4 2m -s = -6
Multiple the second equation by -1 and add together
4m - s = 12
-2m + s = 6
2m = 18 Divide both sides by 2
m = 9 Substitute this in to find the sister's age
2m + 12 = s + 6
2(9) +12 + s + 6
18 + 12 = s + 6
30 = s + 6 Subtract 6 from both sides
24 = s
Questions 5
x + y = 12 x = 5y - 6
Plug in 5y - 6 in the first equation for x
5y - 6 + y = 12 Combine like terms
6y - 6 = 12 Add 6 to both sides
6y = 18 Divide both sides by 6
y = 3
x + y = 12
3 + y = 12 Subtract 3 from both sides
y = 9
I am little confused by this because it says, "The value of the number..." What number are they referring to?
Question 6
To find the rate taking into consideration the walkway rate:
[tex]\frac{48}{3}[/tex] - w Which is equivalent to 16 - w
[tex]\frac{24}{2}[/tex] + w Which is equivalent to 12 + w
Set these expression equal to each other and find the rate of the walkway
16 - w = 12 + w Add w to both sides
16 = 12 + 2w Subtract 12 from both sides
4 = 2w Divide both sides by 2
2 = w
The rate of the walkway is 2 feet per second. Subtract that from 16 or add is to the 12 to get 14 steps per second.

To have the same price, 40 stickers will have to be ordered and the equation is 16 = 0.40p.
What is the equivalent equation?
Equivalent equations are algebraic equations with identical solutions or roots. Adding or subtracting the same number or expression from both sides of an equation yields an equivalent equation. An equivalent equation is created by multiplying or dividing both sides of an equation by the same non-zero number.
We have,
for company A :
Design Fee = $30
Costvper sticker = $0.80
for company B :
Design Fee = $14
Cost per sticker = $1.20
Let the number of stickers = p
Total cost of company A = 30 + 0.80p
Total cost of company B = 14 + 1.20p
For the cost to be the same :
Company A = Company B
30 + 0.80p = 14 + 1.20p
Collect like terms :
30 - 14 = 1.20p - 0.80p
16 = 0.40p
p = 16/0.40
p = 40 stickers
Therefore, to have the same price, 40 stickers will have to be ordered and the equation would be 16 = 0.40p.

Which graph represents the function f(x) = |x − 1| − 3 ?
Answer:
See picture below.
Step-by-step explanation:
f(x) = |x|
This absolute value will have a v shape, the "v" point at (0,0)
Next,
f(x) = |x-1|
This (-1) moves the v shape one unit to the right, "a translation to the right by 1."
Finally,
f(x) = |x-1| - 3
This (-3) moves the v shape down 3 units. This is why the answer is the original
f(x) = |x|
except it's moved right by 1, and down by 3.
Step-by-step explanation:
The graph that represents is translated right by 1 units and 3 unit up to form. Hence, graph (a) is correct.
What is a function?
Function is a type of relation, or rule, that maps one input to specific single output.
The parent function of an absolute function is;
y = |x|
When a function is translated right by h units, the transformation rule by;
y = |x-h|
So:
|x-1|-3 means that it is translated right by 1 units
When a function is translated up k units, then the transformation rule is:
y = |x| + k
y = |x-1|-3
This means that it is translated right by 1 units and 3 unit up to form
Hence, graph (a) is correct

How many 9 in. × 9 in. tiles would be needed to cover a floor that is 288 square feet?
The number of tiles that would be required to cover a floor that is 288 square feet is 512.
According to the question,
We have the following information:
Area of the tile = 9*9 square inches
Area of the tile = 81 square inches
Area of the floor = 288 square feet
So, we will convert the area of the floor from square feet to square inches.
We know that 1 feet = 12 inches.
So, we have the following expression:
Area of the floor = (288*12*12) square inches
Area of the floor = 41,472 square inches
Number of tiles required to cover the floor = area of the floor/area of the tile
Number of tiles required to cover the floor = 41,472/81
Number of tiles required to cover the floor = 512
Hence, the number of tiles that would be required to cover a floor that is 288 square feet is 512.

To describe the temperatures for the week, we can apply the following statistical tools:
a) Find the mean, median, mode, and range.
c) Construct a line graph.
d) Construct a stem and leaf plot.
What are the statistical tools for describing temperatures?We can describe temperatures using measures of central tendencies (especially the mean, median, and mode).
The mean temperature is the average, which shows the overall trend in temperature changes. It is computed by adding up the temperatures for the period and diving by the number of data values.
In addition, the median gives the middle value when the data set is ordered in ascending or descending orders. Similarly, the mode gives the highest temperature occurrence within the period. It may not be useful here.
We can estimate the difference between the highest and lowest temperature for the week with the range.
A line graph (showing connecting lines) and a stem-and-leaf plot (like a bar graph) can graphically describe the temperatures for the week.
Thus, we can use Options A, C, and D to describe the temperature.
