Step-by-step explanation:
for 12
Perimeter (P)
= 2( L + B)
= 2 ( 500 + 300)
=2 * 800
= 1600 cm
For 13
Area
= L * B
= 500 * 300
= 150000 cm²
Step-by-step explanation:
Since Promethean board is rectangle in shape,
So Given,
Dimensions of that board = 500 cm by 300 cm
Hence, Perimeter of the board = 2(l+b)
= 2(500cm + 300cm) = 2 × 800cm
= 1600cm (Ans)(i)
Therefore, area of that board = l × b
= 500cm × 300cm
[tex] = 150000 {cm}^{2} (ans)(ii)[/tex]
What are the coordinates of the point in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6? PLS HELP!!!!
Answer:
The coordinates of the point X:
(x, y) = (-1, -7)Step-by-step explanation:
Let X be the point.
As the point X is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6
i.e.
[tex]\left(x_1,\:y_1\right)\:=\:\left(-2,-8\right)[/tex]
[tex]\left(x_2,\:y_2\right)=\left(5,-1\right)[/tex]
Rise = y₂ - y₁
[tex]= -1 - (-8)[/tex]
[tex]= -1 + 8[/tex]
[tex]= 7[/tex]
Run = x₂ - x₁
[tex]= 5 - (-2)[/tex]
[tex]= 5 + 2[/tex]
[tex]= 7[/tex]
1 : 6 ratio means the point X lies at
[tex]\frac{1}{6+1}=\frac{1}{7}=14\%[/tex]
Thus,
rise for X [tex]=\:7\:\times \:14\%=1[/tex]
run for X [tex]=\:7\:\times \:14\%=1[/tex]
Thus, coordinates of X will be:
[tex]x = -2 + 1 = -1[/tex]
[tex]y = -8 + 1 = -7[/tex]
Therefore, we conclude that:
The coordinates of the point X:
(x, y) = (-1, -7)The point (-1, -7) divide the segment from (-2,-8) to (5,-1). in the ratio 1:6.
What is distance?If a point O(x, y) divides the line segment AB in the ratio of n:m, where the endpoints of the line is A(x₁, y₁) and B(x₂. y₂), the point O is at:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]
Given the ratio 1:6, let O(x, y) divide the segment from (-2,-8) to (5,-1). Hence:
[tex]x=\frac{1}{1+6}(5-(-2))+(-2)=-1\\\\y=\frac{1}{1+6}(-1-(-8))+(-8)=-7[/tex]
O = (-1, -7)
The point (-1, -7) divide the segment from (-2,-8) to (5,-1) in the ratio 1:6.

Write the equation of the line 1x + 3y = 6 in y = mx + b form.
Answer:
y = -1/3x + 2
Step-by-step explanation:
1x + 3y = 6
3y = -x + 6
y = -1/3x + 2
Answer:
[tex]y=-\frac{x}{3}+2[/tex]
Step-by-step explanation:
1x + 3y = 6
We want the y to be isolated, so we subtract x from both sides,
3y = 6 - x
Now we divide everything by 3, to isolate y
[tex]y=-\frac{x}{3}+2[/tex]

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that the number of days required to build is inversely proportional to with the number of workers.
One house was built in 147 days by 4 workers.
So,
147 x 4 = 588
Now the days to build a similar house with 42 workers
588/ 42 = 14

Find the length of the missing side. Simplify all radicals.
Answer:
b = 12
Step-by-step explanation:
Using the Pythagorean Theorem:
a² + b² = c²
You can identify that 12√12 is the hypotenuse, as it is opposite to the right angle.
So:
12² + b² = (12√2)²
144 + b² = [(12√2) (12√2)]
144 + b² = (12 × √2 × 12 × √2)
144 + b² = (144 × 2)
144 + b² = 288
b² = 144
√b² = √144
b = 12
