18. Perimeter of rectangle = 2(l + b)
l = 16m
b = 12m
Perimeter of rectangular park = 2 (12 + 16)
= 24 + 32
= 56m
Perimeter of square park = 56m
(given that, perimeter of rectangular and square park are equal)
Perimeter of square = 4a
4a = 56
a = 56/4
a = 14m
Area of square park = a²
= 14²
= 196m²

Answer: 3. Distributive
Step-by-step explanation:
3(x -2y) = 3x - 6y To get from left to rigth, you have to multiply them which is the same as distribitue.
3(x) - 3(2y) = 3x - 6y
The Coney Island Boardwalk is 2.7 miles long. A person jogged at the average speed of 6 mph. How long will it take the person to walk the boardwalk to the end and back?
Answer:0.9
Step-by-step explanation:
The speed of an object is defined as the ratio of distance travelled by it to the time taken. It will take a person 0.9 hours to walk end and back .
What is Speed?Speed is the ratio of distance and time. It is a measure of how fast or slow an object is moving. A high speed object takes less time to travel the same distance as compared to a low speed object.
Given length of island is 2.7 miles.
Speed of the person is 6 mph.
Thus total length for travelling end and back 2.7 + 2.7 =5.4 miles.
Time taken = distance/speed
Therefore, time taken by the person is given as, time is 5.4/6 = 0.9 hours.
Hence, the person will have to take 0.9 hours to walk island end and back.

the sum of two numbers is 18 their difference is 8
Answer:
13 and 5
Step-by-step explanation:
x+y=18
x-y=8
_____
2x=26
x=13
So the first number must be 13
13+y=18
y=5
And the second number must be 5
When we write out the system of equations, we will get:
x+y=18
x-y=8
We can then use elimination to get just one variable.
x+y=18
+x-y= 8
Which gives us: 2x=26
We then divide by 2 and get: x=13
We next plug that into one of the two equations and solve for the other variable: (13)+y=18
We subtract 13 from both sides and get: y=5
So the two numbers are 13 and 5.

Two individuals heterozygous for gene Q produced gametes by meiosis, then mated and fertilized one egg. What is the probability that both the egg and sperm will carry the recessive allele?
Answer:
0.25
Step-by-step explanation:
Following the law of segregation which states that only one of the two gene copies noticeable in an organism is diffused to each gamete (egg or sperm cell) and gene allocation is random.
A heterozygous gene for Q = Qq
If these two individuals mate and produce gametes by meiosis,
The probability that both the egg and sperm will carry the recessive allele is determined as follows:
Qq × Qq
Q q
Q QQ Qq
q Qq qq
The probability that both the egg and sperm will carry the recessive allele qq is 25% or 0.25

Step-by-step explanation:
A number of squares are connected in a row to form a rectangle. The table shows the relationship between the number of squares, x, and the
perimeter, y, of the rectangles they form
Select all the true statements about this relation.
Answer:
✅The table can be represented by the equation, [tex] y = 4x + 4 [/tex]
✅The relation is a function.
✅The graph of the function is linear.
Step-by-step explanation:
✍️The first statement: The table can be represented by the equation, [tex] y = 4x + 4 [/tex].
To check if the first statement is correct let's find the equation that can represent the table by finding the slope (m) and y-intercept (b).
Using two pairs, (1, 8) and (2, 12),
Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 8}{2 - 1} = \frac{4}{1} = 4 [/tex].
Substitute, x = 1, y = 8, and m = 4 into y = mx + b to solve for b.
Thus:
8 = (4)(1) + b
8 = 4 + b
Subtract 4 from each side
8 - 4 = b
4 = b
Plug in the values of b and m into y = mx + b.
Thus, the equation that represents the table would be:
[tex] y = 4x + 4 [/tex].
✅Therefore, the first statement is correct.
✍️The second statement: The graph of the function is non-linear.
This is NOT TRUE because the equation of the function, [tex] y = 4x + 4 [/tex], represents the equation of a linear graph in the slope-intercept form. When graphed, it will give us a straight line.
✍️The Third statement: The relation is a function.
This is TRUE because each input value (x-value) has exactly one output value (y-value).
✍️The Fourth statement: The rate of change is NOT constant.
This standby is NOT TRUE.
The rate of change is the slope (m) that we have calculated above to be 4. Between any two pairs, the rate of change remains 4.
Therefore, this statement is not correct.
✍️The Fifth statement: The graph of the function is linear.
This is TRUE. As stated earlier, from the equation generated, it is safe to say that the equation represents graph of a linear function. The graph will be a straight line graph.
The true statements are:
(a) The equation of the function is [tex]\mathbf{y = 4x +4}[/tex](c) The relation is a function(e) The graph is linear(a) The equation of the function
Start by calculating the slope (m)
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 -x_1}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{12 - 8}{2 -1}}[/tex]
[tex]\mathbf{m = 4}[/tex]
The equation is then calculated as:
[tex]\mathbf{y = m(x -x_1) + y_1}[/tex]
So, we have:
[tex]\mathbf{y = 4(x -1) + 8}[/tex]
[tex]\mathbf{y = 4x -4 + 8}[/tex]
[tex]\mathbf{y = 4x +4}[/tex]
Hence, this statement is true
(b) The graph is nonlinear
Because of (a) above, the graph is linear
Hence, this statement is false
(c) The relation is a function
A linear relation is a function
Hence, this statement is true
(d) The rate of change is not constant
Because of (a) above, the rate of change is constant
Hence, this statement is false
(e) The graph is linear
Because of (a) above, the graph is linear
Hence, this statement is true

The first three terms of the binomial expansion of (2 – ax)" are 64 – 16bx +100bx?.
Find the value of each of the integers n, a and b.
Ans: n=6, a=5, b=60
Answer:
n = 6, a = 5, b = 60
Step-by-step explanation:
In a binomial function (a + b)ⁿ expression that represents the terms,
(a + b)ⁿ = [tex]\sum_{k=0}^{n}\binom{n}{k}a^{n-k}b^k[/tex]
By this formula,
1st term = [tex]\binom{n}{0}a^{n-0}b^0[/tex] = aⁿ
2nd term = [tex]\binom{n}{1}a^{n-1}b^1[/tex] = [tex]n.a^{n-1}b^1[/tex]
3rd term = [tex]\binom{n}{2}a^{n-2}b^2[/tex] = [tex]\frac{n(n-1)}{2}.a^{n-2}.b^2[/tex]
For the binomial expansion initial 3 terms of (2 - ax)ⁿ = 64 - 16bx + 100bx²
Terms of (2 - ax)ⁿ = [tex]2^n+n(2)^{n-1}(-ax)+\frac{n(n-1)}{2}(2)^{n-2}(-ax)^2[/tex]
= [tex]2^n-n(2)^{n-1}(ax)+n(n-1)(2)^{n-3}(a^2x^2)[/tex]
Comparing the terms of both the expansions,
1st term
2ⁿ = 64
2ⁿ = 2⁶
n = 6
2d term
[tex]n(2)^{n-1}(ax)=16bx[/tex]
[tex]6(2)^{6-1}(a)=16b[/tex]
192a = 16b
b = 12a -----(1)
3rd term
[tex]n(n-1)2^{n-3}(a^2x^2)=100bx^2[/tex]
[tex]6(6-1)2^{(6-3)}(a^2)=100b[/tex]
[tex]30(2)^3(a^2)=100b[/tex]
240a² = 100b
b = 2.4a² -----(2)
From equation (1) and (2),
b = 12a = 2.4a²
a = [tex]\frac{12}{2.4}=5[/tex]
From equation (1)
b = 12a = 60
Therefore, n = 6, a = 5, b = 60

What is the slope of any line that is perpendicular to the line that contains the points (8, 8) and (12, 12)?
Answer:
slope(m)=-1
Step-by-step explanation:
let the point (8,8) and (12,12) be ([tex]x_{1}[/tex],[tex]y_{1}[/tex]) and ([tex]x_{2} , y_{2}[/tex])
slope of point([tex]m_{1}[/tex])=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
=(12-8)/(12-8)
=1
let the slope of perpendicular line to given point be [tex]m_{2}[/tex]
now ,
[tex]m_{1} m_{2}[/tex]=-1

A hairstylist schedules 14 hour to trim a customer's hair and 16 hour to style the customer's hair. The hairstylist plans to work 3 13 hours each day for 5 days each week. How many appointments can the hairstylist schedule each week if each customer must be trimmed and styled?
Answer:
40 customers
Step-by-step explanation:
Trimming = 1/4 hours
Styling = 1/6 hours
Working hours per day = 3 1/3 hours
Working days per week = 5
Total work time per week :
3 1/3 * 5 = 10/3 * 5 = 50 / 3 hours
Time taken for styling and trimming :
1/4 + 1/6 = (3 + 2) / 12 = 5/12
Number of appointments stylist can schedule each week :
Total work time / time taken per person
(50 / 3) ÷ (5 / 12)
(50 /3) * (12 /5)
(50 * 12) / (3 * 5)
= 600 / 15
= 40
