According to the given statement the area of the right angle triangle:
= 18 cm².
What is right angle triangle?A right triangle, sometimes known as a right-angled triangle, or perhaps more formally called an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle or two perpendicular sides. Trigonometry is founded on the relationship between the sides and some other angles of a right triangle.
According to the given information:Given value
A = 6cm
B = 6cm
Using the right angle triangle area formula:
Area = (a*b)/2
= (6 *6)/2
= 18 cm²
According to the given statement the area of the right angle triangle:

The midpoint of segment EF is M(4, -1). Find endpoint F if the other endpoint E is at E(2, 3).
The x and y coordinates of the endpoint F are (6,-5)
The midpoint of a line segment is a point that is situated exactly at the middle from the two ends of the line segment
The coordinate of the mid-point or any other point can be found using the section formula.
For a point P with coordinates, the section formula is as follows: (x,y)
which divides the line segment A(x1,y1), B(x2,y2) in the ratio m:n, is given by the equation
Px=mx2+nx1/m+n Py=my2+ny1/m+n
Because the midpoint divides the line segment equally, m and n are both 1 in the midpoint case.
Thus the formula becomes
Px=1*x2+1*x1/1+1 Py = 1*y2+1*y1/1+1
where Px and Py are x and y co-ordinates of the point x and y
It is now assumed that midpoint M has coordinates (4,-1)
Point E is given by (2,3)
We are required to find F
Thus using section formula,
Mx=2+x/2 My=-3+y/2
4=2+x/2 -1=1+y/2
8-2=x -2-3=y
x=6 -5=y
Therefore, the coordinates of x and y of the endpoint F are(6,-5)

if the pressure in the right tire is found to be 22 psi, what is the probability that the left tire has a pressure of at least 25 psi?
Considering the given probability distribution, we have that there is a 0.349 = 34.9% probability that the left tire has a pressure of at least 25 psi.
What is the probability distribution?The probability distribution for the air pressure of the tires of the car(X right, Y left) is given as follows:
f(x,y) = K(x² + y²), 18 ≤ x ≤ 28, 18 ≤ y ≤ 28.f(x,y) = 0, otherwise.The pressure in the right tire is found to be 22 psi, hence y = 22 and:
f(x,y) = K(x² + 484), 18 ≤ x ≤ 28.f(x,y) = 0, otherwise.The value of K is found considering that the sum of all probabilities has to be 1, hence:
[tex]\int_{18}^{28} K(x^2 + 484) dx = 1[/tex]
[tex]\frac{Kx^3}{3} + 484Kx\lbracket|_{x = 18}^{x = 28} = 1[/tex]
Applying the Fundamental Theorem of Calculus:
7317.33K + 13552K - 8712K - 1944K = 1
10213.33K = 1
K = 1/10213.33
K = 0.000098.
The probability that the left tire has a pressure of at least 25 psi is:
[tex]P(X \geq 25) = \int_{25}^{28} 0.000098(x^2 + 484) dx[/tex]
[tex]P(X \geq 25) = 0.000098\int_{25}^{28} (x^2 + 484) dx[/tex]
[tex]P(X \geq 25) = 0.000098\left(\frac{x^3}{3} + 484x\right)_{x = 25}^{x = 28}[/tex]
[tex]P(X \geq 25) = 0.000098(7317.33 + 13552 - 5208.33 - 12100)[/tex]
[tex]P(X \geq 25) = 0.349[/tex]
0.349 = 34.9% probability that the left tire has a pressure of at least 25 psi.

wire 19 cm long is cut into two pieces. the longer piece is 3 cm longer than the shorter piece. find the length of the shorter piece of wire
The shorter piece of wire is 8 cm long when the total length of the wire is 19 cm long.
We are given that:
a wire's length is 19 cm.
We have to cut the wire into two pieces.
We are also given that the longer piece of wire is 3 cm longer than the shorter piece.
Let the shorter piece of wire be x cm
Longer piece = x + 3 cm.
So, the equation formed will be:
x + x + 3 cm = 19 m
2 x + 3 cm = 19 cm
2 x cm = 19 cm - 3 cm
2 x cm = 16 cm
x = 16 / 2 cm
x = 8 cm.
Therefore, the shorter piece of wire is 8 cm long.

Miss Tyrrell catches the 9:45am bus from Leeds to London.
The distance between the two cities is 195 miles.
The bus travels at an average speed of 52 mph.
What time should she arrive in London?
Answer:
The time she would arrive in London is 1:20 pm
Step-by-step explanation:
Recall
Speed= Distance/Time
But we want to find the time taken, so:
We cross multiply:
Speed *Time = Distance
Make time the subject of formula
Time= Distance/Speed
195/52
= 3.75 hours
Therefore, 9:45 am + 3.75 hours
= 13.20 pm
Which is equivalent to 1:20 pm
Pedro uses cardboard to make a model of a square pyramid. The edges of the base of the model are 5 in. long. The height of each triangular face is 4 in. What is the area of the cardboard in Pedro's model? Show your work.
The area of the cardboard in Pedro's model is 190 sq inches.
What is lateral and total surface area ?The only difference between lateral surface area and total surface area is in lateral surface area we only consider the side views and neglect the top and bottom on the other hand for total surface area we consider all sides.
As a sphere has no side it has only total surface area which is 4πr².
According to the given question Pedro uses cardboard to make a model of a square pyramid.
Also given that the edges of the of the model is 5 in. long and the height of the triangular face is 4 in.
As to make the base of the pyramid with is square we need to form a cube which has sides = height = 5 inches.
We know the total surface area of a cube is 6(side)² which is
= 6(5)² sq inches.
= 6(25) sq inches.
= 150 sq inches.
Now for the upper triangular part we need 4 triangles with height 4 inches and as the base of the cube is 5 inches therefore the base of the triangle will also be of 5 inches.
We know area of a triangles with given height and base is
= (1/2)×base×height.
So for four such triangles the area will be 4 times of this.
= 4[(1/2)×5×4] sq inches.
= 4[10] sq inches.
= 40 sq inches.
So, the total area of the square pyramid model will be (150 + 40) = 190 sq inches.

If f(x + 3) = x^2 + 4x − 7, find f(2).
The complete statement is that if the equation of the function f(x + 3) = x^2 + 4x − 7, the value of the function f(2) is -10
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine the solution to the quadratic equation?A quadratic equations can be split to several equations and it can be solved as a whole
In this case, we have
f(x + 3) = x^2 + 4x − 7
To find f(2), we make use of the following comparison
f(2) = f(x + 3)
This means that
2 = x + 3
Evaluate
x = -1
Substitute x = -1 in f(x + 3) = x^2 + 4x − 7
f(-1 + 3) = (-1)^2 + 4(-1) − 7
This gives
f(2) = -10
Hence, the complete statement is that if the equation of the function f(x + 3) = x^2 + 4x − 7, the value of the function f(2) is -10

Solve the system by elimination 2x - y = 1 and x - 2y = -1
Answer:
x = 1 and y = 1
Step-by-step explanation:
Let's solve your system by elimination.
2x − y = 1 and x − 2y = −1
Multiply the second equation by -2, then add the equations together.
(2x−y=1)
−2(x−2y=−1)
Becomes:
2x−y=1
−2x+4y=2
Add these equations to eliminate x:
3y=3
Then solve3y=3for y:
3y=3
3y3=33(Divide both sides by 3)
y=1
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:

Substitute1foryin2x−y=1:

Thus, nth term of an arithmetic sequence is given as,
Tn = a1 + (n - 1)d
For 13th term put n = 13

If 25% of a number is 75 and 35% of the same number is 105, find 10% of that number.
Answer:
30
Step-by-step explanation:
to find 10%, find 100% first
because we know what 25% is, the easiest way we can work this out is multiply 25% by 4
so:
[tex] 4 \times 25\% = 100\%\\\\ 75 \times 4 = 300[/tex]
this means that 100% is 300.
now to find 10% all we have to do is divide the number by 10.
[tex]300 \div 10 = 30[/tex]
so 10% is 30
to check we're right, we make sure that 25% and 10% = 35%
75 + 30 = 105, meaning our percentages are correct
