The area of the given diagram is 270sq.metre
What is Area of Rectangle?The area of Rectangle is length times of width.
In the given figure there we can see three rectangles.
Let us divide each length to three parts.
The length 27m is divided into 3 we get
27/3=9m.
Hence each rectangle has 9m of length.
The width 30m is divided into 3 parts we get,
30/3=10m.
Hence area of each rectangle is 9×10=90 sq. m
Total area of diagram will be
3 times of 90.
270 sq.m.
Hence the area of the given diagram is 270sq.metre

The perimeter of a college basketball court is 96 meters and the length is 14 meters more than the width. What are the dimensions?
Perimeter = 2 x Length + 2 x Width
Answers
Answer:
Step-by-step explanation:
Let L be the length and W the width
Perimeter of a rectangle is P = 2L + 2W
We are told that L = W + 14 (m) [the length is 14 meters more than the width]
Area of a rectangle is A = L*W
We learn that A = 96 m^2
L*W = 96
Since L = W + 14, we can substitute:
L*W = 96
(W + 14)*W = 96 m^2
W^2 + 14W = 96
W^2 + 14W - 96 = 0
The solution to W in the above equation is 5.04 m
This means L = 5.04 m + 14 m
L = 19.04 meters
Perimeter = 2W + 2L
Perimeter = 2(5.04) + 2(19.04) = 96 m^2
For a particular rectangle, twice the width is 4 meters shorter than the length. The area of the rectangle is 126 square meters. What is the perimeter of the rectangle? ? meters
Answers
Let l be the length of the rectangle and w its width.
Then its area is given by:
a = l*w
Its perimeter is given by:
p = 2l + 2w
We also know that, for this specific triangle, we have:
2w = l - 4
l = 2w + 4
a = 126 m²
Applying this result in the area formula, we have:
w*l = 126
w(2w + 4) = 126
2w² +4w = 126
2w + 4w - 126 = 0
Therefore, w = 7 m and l = 2*7 + 4 = 10 m
Then, the perimeter is given by:
p = 2*18 + 2*7 = 36 + 14 = 50 m

Answers
The domain of the given function given range is {1.25, -0.25, 1.25, 4.75}
Domain and range of a functionThe range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f(x) make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of value.
Given the range of the function as {-5, -3, 0, 7}
Determine the domain from the function 4x - 2y = 5
4x - 2y = 5
4x - 2(-5) =5
4x + 10 = 5
4x = 5
x = 5/4 = 1.25
If y = -3
4x - 2y = 5
4x - 2(-3) =5
4x + 6 = 5
4x = -1
x = -1/4 = -0.25
If y = 0
4x - 2(0) =5
4x - 0 = 5
4x = 5
x = 5/4 = 1.25
If x = 7;
4x - 2y = 5
4x - 2(7) =5
4x - 14 = 5
4x = 19
x = 19/4 = 4.75
Therefore the equivalent domain of the function is {1.25, -0.25, 1.25, 4.75}

The shortest side of a right triangle measures 5, and the longest side measures 13. Determine the measurement of the unknown side.
Answers
Using the Pythagorean Theorem formula, the measurement of the unknown side (base) is 12 units.
How can the measurement of the unknown side of a right triangle be determined?According to the Pythagorean Theorem formula, c² = √a²+b², where c = hypotenuse, a = perpendicular, and b = base.
The hypotenuse is the longest side of a right triangle.
The shortest side is the perpendicular (adjacent side) while the other side is the base (opposite side).
Since the hypotenuse is given as equal to the square root of perpendicular squared and the base squared, we can compute the base, unknown side, using the following Pythagorean Theorem formula.
c² = √a²+b²
The perpendicular (shortest side) of a right triangle = 5
The hypotenuse (longest side) = 13
c² = √a²+b²
169 = √5²+b²
169 = √25 + b²
The base (unknown side):
b² = 169 - 25
b² = 144
The square root of √144 = 12
b = 12
Thus, the unknown side of the right triangle is the base, measuring 12 units.

As per the given question, here H = 13 and P = 5
Substitute the values of H = 13 and P = 5 in the Pythagorean Theorem,
(13)² = (5)²+ B²
169 = 25 + B²
B² = 169 - 25
B² = 144

Tom’s car has 11 1/9 gallons of gas. If he uses 38 of the gas, how much gas does the car have left?
Answers
Answer: 6 [tex]\frac{17}{18}[/tex] gallons of gas left in the car
Step-by-step explanation:
Upon further clarification, this question reads "3/8 of the gas" and not "38 of the gas."
If Tom's car has 11 1/9 gallons of gas, and we want to know how much gas the car will have left if he uses 3/8 of that, we first need to find 3/8 of 11 1/9.
"Of" can usually be written as multiplication.
3/8 of 11 1/9 = 3/8 * 11 1/9 = 4 1/6
Next, we will use subtraction since he uses 4 1/6 gallons of gas.

Step-by-step explanation:
Lauren needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3.75 hours and charged her $119 for parts. The total was $400.25. Write and solve an equation which can be used to determine a, the cost of the labor per hour.
3.75x + parts = $400.25
so:
3.75x + $119 = $400.25
subtract $119 from both sides:
3.75x + $119 - $119 = $400.25 - $119
3.75x = $281.85
divide both sides by 3.75
3.75x/3.75 = $281.85/3.75
x = $75
so the tech charged $75 per hour.

The number of degrees in the angle measured counterclockwise from the north line to the line connecting the center of the compass is the bearing of a point.

What is a logarithm?The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number. When measuring the relative change of a value rather than its absolute difference, logarithmic scales are helpful. Moreover, logarithmic scales are used to compress large-scale scientific data because the logarithmic function log(x) grows very slowly for large x. Common logarithms, with a base of 10, binary logarithms, with a base of 2, and natural logarithms, with a base of e 2.71828, are the four most popular types of logarithms.So, 4√(384.5)³ using logarithm:

growth rate in the initial population of 1.08.. So, the equation for solving this population growth problem is 10,000(1.08) ²⁰
Before twenty years, the actual population was 10,000.
Population growth per year = 8% = ((100+8)10,000)/100=10,800.
So, there will be an addition of 800 people to the population every year.
After a period of twenty years, the total population was 10,000 + 19×(800) = 25,200.
Population for t years = (Initial Population)× (Growth or Decay Rate)×time
Using the above population increment formula,

Answer:
Step-by-step explanation:
Step 1: Assume your variables
We can see that the money is being saved on a weekly basis.
So, let's assume the number of weeks for which the money is being saved to be the variable: [tex]x[/tex]
And let's consider the total cost after [tex]x[/tex] weeks to be: [tex]y[/tex]
Step 2: Manipulate the variables according to the information given
$7 is being saved each week.
So, in one week, [tex]\$7[/tex] is saved.
In two weeks, [tex]\$(7\times 2)[/tex] is saved.
So, in [tex]x[/tex] weeks, [tex]\$(7\times x)[/tex] is saved.
Step 3: Create the equation
In words, the equation will be as such:
Total cost after [tex]x[/tex] weeks = Amount saved in [tex]x[/tex] weeks
Upon representing this mathematically, we get:
[tex]y=7\times x\\y=7x[/tex]
The equation [tex]y=7x[/tex] can be used to find the total cost.

t 0 1 2 3 4 5
v 0 1 2 3 4 5
A vertical line drawn from the independent variable axis (x-axis) meets the function graph only once because a function is a relationship between an input and an output in which each input has just one output.
The independent variable is the input, while the dependent variable is the output.
Filling out the table in such a way that when t is the independent variable, the relationship is a function, and when t is the dependent variable, the relation is not a function, results in the following table:
t 0 1 2 3 4 5
v 0 1 2 3 4 5
Given that each value of the independent variable t has a corresponding value of the velocity v, the aforementioned is a function.
However, when t is the dependent variable, the independent variable value of 1 produces two outputs of 1 and 5, which results in the following table:
t 0 1 2 3 4 5
v 0 1 2 3 4 5

The position of N on the line segment is at the -14 mark
What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
How to determine the location of N?The complete question is added as an attachment
From the attachment, we have
The ratio is given as:
MN : NP = 7 : 2
Also, we have
Location of M = -27
Location of P = -9
The location of N is then calculated as
N = MN/(MN + NP) * (M - P)
Substitute the known values
N = 7/(7 + 2) * (-27 + 9)
Evaluate the sum
N = 7/9 * -18
Evaluate the product
N = -14
Hence, the location of point N is -14
