area of rectangular park=236m²
Step-by-step explanation:
area of rectangular park=236m²
l×(l-10)=236
l²-10l-236=0
l²-2.l.5+5²-236-5²=0
(l-5)²-236-25=0
(l-5)²=261
(l-5)=√261
(l-5)=16.15
l=16.15+5=21.15

Write the equation of the line in slope-intercept that has passes through the points (-8,-11) and (10,-2).
Answer:
y = 0.5x-7
Step-by-step explanation:
First we need to find the slope so we use the formula y2 - y1 / x2 - x1 = m
The variable m will represent the slope or rate of change
-2 - (-11) / 10 - (-8) = m
Or
-2 + 11 / 10+8 = m
9/18 = m
0.5 = m
y = 0.5x+b
To find b replace the y and x variables
I will use 10 and -2
-2 = 0.5(10)+b
You should come out with -7 = b
Ana starts work at 2:45pm and finshes work at 5:30pm .How much times does Ana spend working
Answer:
2 hours and 45 minutes
Step-by-step explanation:
you add the 15 and 30 and then add 2 hours.
Ana spent 2 hours and 45 minutes working.
What is Unitary Method?Unitary method is a technique used in mathematics to solve problems that involve proportional relationships. It involves finding a unit rate (i.e., a rate per unit) and using it to solve problems that involve different quantities of the same type of unit.
To find the amount of time Ana spent working, we need to subtract the starting time from the finishing time.
The starting time is 2:45 pm and the finishing time is 5:30 pm.
We can subtract the starting time from the finishing time as follows:
5:30 pm
2:45 pm
2:45 pm
So, Ana spent 2 hours and 45 minutes working.

The heights of adult men are normally distributed with a mean of 69 inches and a standard deviation of 2.75 inches. What percentile does a man who is 72 inches fall?
Answer:
86.2%
Step-by-step explanation:
Given that:
Mean, m = 69 inches
Standard deviation. s = 2.75
Man who is 72 inches tall ; x = 72
Using the relation :
Zscore = (x - mean ) / standard deviation
Zscore = (72 - 69) / 2.75
Zscore = 3 / 2.75 = 1.09
Z = 1.09
P(Z < 1.09) = 0.862 (Z probability calculator)
0.862 * 100% = 86.2%

what is the median of the following 9 numbers 23,15,32,27,19,22
22.5 i think but i have no idea good luck
The median of the following 9 numbers 23,15,32,27,19,22 is 22.5.
What is median?The median is the value that splits the mathematical numbers or expressions in the half. The median value is the middle number of data point. to find the median firstly arrange the data points in ascending order.
Arrange the data points from smallest to largest;
15, 19, 22, 23, 27, 32.
Total number of data points is 6. And 6 is the even number.
So median of even numbers of data points is average of two middle points.
And those numbers are 22 and 23.
Average of 22 and 23 is (22 + 23) / 2 = 22.5
Therefore the median is 22.5.

Adam divides 32/8032. In which place should he write the first digit of the quotient?
Answer:
We have a quotient between a 2 digit number and a 4 digit number.
The usual rule for this type of problems is:
If the denominator has n more digits than the numerator, then the first digit will be in the nth position at the right of the decimal point.
If also, the denominator is larger than the numerator times 10^n, then the decimal will be moved another place to the right.
For example, if we divide 10 by 100 we have:
10/100
The denominator has one more digit than the numerator, then n = 1.
this means that the first digit of the quotient, will be on the first place at the left of the decimal point.
We can solve the quotient to get:
10/100 = 0.1
And, as we predicted, the first decimal is in the first place.
Now, with our quotient we have:
32/8032
n = 2.
and:
32*10^n = 3200
The denominator is larger than this, then we will move the first decimal to another place to the right.
Then we should expect to have the first decimal in the third place after the decimal point.
We can solve the quotient to get:
32/8032 = 0.0039
As we expected.

The trainers at Atlantis Aquarium perform shows about sea life. Yesterday, they performed 4 shows in 2 hours. Today, they will perform 6 shows. If they perform shows at the same rate, how many hours will the trainers spend performing shows today?
Answer:
3 hours
Step-by-step explanation:
Number of shows : Time taken
= 4 : 2
Today, they will perform 6 shows.
Number of shows : Time taken
= 6 : x
Equate both ratios to find x
4 : 2 = 6 : x
4/2 = 6/x
Cross product
4 * x = 2 * 6
4x = 12
x = 12/4
x = 3 hours
The trainers will spend 3 hours performing shows today

3 hours

Write the equation for this graph in the form y=mx+b
Answer: y = 2x + 50
Step-by-step explanation:
first find the slope (m):
slope = rise/run = y1-y2/x1-x2
(1,52); (2,54)
slope = (54-52)/(2-1) = 2/1 = 2; m = 2
now since we have the slope and a point, we will put it into point-slope form:
y = m(x - x1) + y1
y = 2(x - 3) + 56
y = 2x - 6 + 56
y = 2x + 50

The area of a circle is 9π ft². What is the circumference, in feet? Express your answer in terms of \piπ. (pi)
Answer:
6π feet.
Step-by-step explanation:
The area = π r^2 = 9π
So r^2 = 9π/π = 9
r = 3 ft.
So the circumference = 2πr
= 2*π*3
= 6π feet.
The circumference of a circle with radius 3 feet is 6π feet.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know the perimeter or circumference of a circle is 2πr and the area
is πr².
Given, The area of a circle is 9π ft².
Therefore, πr² = 9π.
r² = 9.
r = 3.
Now, we have a circle with a radius of 3 feet.
So, The circumference of the circle with radius 3 feet is,
= 2π×3 feet.
= 6π feet.
So, The circumference of the circle is 6π feet.

The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x.
Answer:
The value of x is 6
Step-by-step explanation:
The perimeter of an equilateral triangle is P = 3 × S, where S is the length of each side
∵ The perimeter of an equilateral triangle is 63 inches
∴ P = 63 inches
→ By using the rule of the perimeter above
∵ P = 3 × S
→ Equate the right sides of P
∴ 3 × S = 63
→ Divide both sides by 3
∴ S = 21 inches
∴ The length of each side is 21 inches
∵ The length of each side is (4x - 3)
→ Equate (4x - 3) by the length of each side
∴ 4x - 3 = 21
→ Add 3 to both sides
∵ 4x - 3 + 3 = 21 + 3
∴ 4x = 24
→ Divide both sides by 4 to find x
∴ x = 6
∴ The value of x is 6
