Building A is 200 feet shorter than Building B. The total height of the two buildings is 1510 feet. Find the height of each building.
As per given relation about the height of the buildings , the height of building A is 655 feet and height of building B is 855 feet.
As given in the question,
Let us consider height of building A is equal to x feet.
According to given condition height of building A is 200 feet shorter than building B.
Height of building B is equal to ( x + 200 ) feet.
Total height of building A and building B is equal to 1510 feet
Required equation is :
x + x + 200 = 1510
⇒ 2x + 200 = 1510
⇒ 2x = 1510- 200
⇒ 2x = 1310
⇒ x = 655 feet
Height of building B is :
x+ 200 = 655 + 200
= 855 feet
Therefore, for the given relation about the height of the buildings , the height of building A is 655 feet and height of building B is 855 feet.

Write the linear equation in standard form. Do not use any spaces in your answer.
2 + (1/2)x = y
By writing both variables in the same side of the linear equation, we will get the standard form:
2y + (-1)*x = 4
How to write the linear equation in standard form?A linear equation between two variables x and y written in standard form is:
a*x + b*y = c
Where the coefficients a, b, and c, are all real numbers.
In this case, we have the linear equation:
2 + (1/2)*x = y
If we multiply both sides by 2, we get:
2*(2 + (1/2)*x) = 2*y
4 + x = 2y
Now we subtract x in both sides to get:
4 + x - x = 2y - x
4 = 2y - x
This is the linear equation in standard form:
2y + (-1)*x = 4

what is the remainder when P(x)=x3-x2-2x+8 is divided by (x+2)
The remainder when the polynomial P(x)=x3-x2-2x+8 is divided by (x+2) is 0
Remainder Theorem
From the definition of remainder theorem which stated that , if a polynomial f(x) is divided by a binomial (x−a), then the remainder is f(a)
Using the remainder theorem, P(x)=x3-x2-2x+8 is divided by (x+2).
binominal (x-a)
Step 1: We divide p(x) by (x + 2)
P(x)=x3-x2-2x+8 and X = -2
therefore, Remainder = p(-2)
Step 2: Substitute the value of the remainder into p(x)
P(-2) =[tex](-2)^{3}[/tex] -( [tex]-2^{2}[/tex] ) - 2([tex]-2[/tex]) + 8
P(-2) = -8 - 4 + 4 + 8
P(-2) = -12+12
P(-2) =0

how many soluitons does 3x - 13 = 7(x + 2) - 4(x - 7) have?
The equation, 3·x - 13 = 7·(x + 2) - 4·(x - 7), has no solution
What are the types of solutions of an equation?An equation can have no solution, infinitely many solutions or one solution
The equation is; 3·x - 13 = 7·(x + 2) - 4·(x - 7)
Expanding the left and right expressions of the equation, gives;
3·x - 13 = 7·x + 7×2 - 4·x + 4 × 7
Collecting like terms gives;
3·x - 13 = 7·x + 14 - 4·x + 28 = 7·x - 4·x + 14 + 28
3·x - 13 = 7·x - 4·x + 14 + 28 = 3·x + 42
3·x - 13 = 3·x + 42
3·x - 13 + 13 = 3·x + 42 + 13 = 3·x + 55
3·x + 0 = 3·x + 55
3·x = 3·x + 55
3·x - 3·x = 55
3·x - 3·x = 0 = 55 (No solution for x)
Therefore, the value of x in the equation, 3·x - 13 = 7·(x + 2) - 4·(x - 7) has no solution as the left and right expressions are not the same

The 65 represents the speed.
97.5 miles covered in 1.5 hours.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given: d= 65t
We know the Formula of Speed- distance
speed= Distance / time
and, distance = speed x time
So, comparing it with given equation
distance =d , time= t and speed= 65
Now, t=1.5 hours
Distance = 1.5 x 65 = 97.5 miles
and, d= 26 miles
t= 26 / 65

(-1, 6). What is the equation in
slope-intercept form of line k?
The equation in slope-intercept form of line k is y = - x + 5.
What is the equation of the line?
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept.
The equation of a line in slope- intercept form is
y = mx + c
where,
m is the slope and c the y- intercept.
We have,
y = x - 3
∴ It is in the slope intercept form.
with slope m = 1
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular} = -\frac{1}{m} = -\frac{1}{1} = -1[/tex] ,
The partial equation of line j is,
y = - x + c
By substituting (2, 0) into the partial equation we get, c
0 = - 2 + c
c = 0 + 2 = 2
∴ c = 2
The equation of line j is y = - x + 2.
Similarly,
The slopes of parallel lines are the same.
The partial equation of line k is,
∴ y = - x + c
By substituting (- 1, 6) into the partial equation we get, c
6 = 1 + c
c = 6 - 1 = 5
∴ c = 5
The equation of line k is y = - x + 5.

What is Sine function?The function y =[tex]sin x[/tex] defines a sine wave as a geometric waveform that oscillates (moves up, down, or side to side) frequently.
It is an s-shaped, smooth wave that oscillates above and below zero, to put it another way.

Given:
Amplitude = 3
midline= 5
As, we know
General sine function: a sin b[tex](x- c)[/tex] + d
and, amplitude = absolute value of a
b = 2π / period
c = phase shift (horizontal shift)
d = vertical shift (i/e., midline is y = d)
So,
a = 5, d = 3, and b = 2π / (1/8) = 16π, c = 0

The values of ∠PQR = 45° and ∠POR = 90°.
The circumference of a circle is defined as its linear distance around it. In other words, if a circle is opened to form a straight line, the length of that line equals the circumference of the circle.
The radius of a circle is the distance between the circle's center and any point on its circumference. It is usually denoted by the letters 'R' or 'r'.
Given that
O is the center of the circle, if ∠OPQ = 25° &∠ORQ = 20°
We have to determine the values of ∠PQR and ∠POR
Sol. OP = OQ
⇒∠OQP = ∠OPQ = 25° [Radii of the same circle]
Similarly, ∠OQR = 20°
∠PQR = 25° + 20°
∠PQR = 45°
Furthermore ∠POR = 2 ∠PQR [the angle at the centre is twice the angle at the circumference].
⇒∠POR = 2 × 45°
∠POR = 90°.
Therefore the values of ∠PQR = 45° and ∠POR = 90°.

If Bisector BD bisects ∠ABC. and ∠ABD= 67°, m∠CBD= 67°then m∠ABC= 134
As given, bisector BD bisects the angle ABC so this means, the angle ABC is divided into two halves. We need to find ∠ABC
So,
angle ABD= angle CBD.
and ∠ABD= (8x + 35)° (i)
∠CBD= (11x + 23)° (ii)
So,
(8x + 35)° = (11x + 23)°
On solving the above equation, we have
3x= 12
x= 4.
Putting x=4 in (i) we have,
∠ABD= 8(4) + 35
∠ABD= 67°
As ∠ABD = ∠CBD, we have
∠CBD= 67°
Now,
∠ABC= ∠ABD + ∠CBD
∠ABC= 67° + 67°
∠ABC= 134°.
