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]

n/3
Probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given
Probability that Sara wins a raffle is given by the expression
P(win) = [tex]\frac{n}{n+3}[/tex]
Probability that Sara does not wins a raffle is given by
P(does not win) = 1 - [tex]\frac{n}{n+3}[/tex]
= [tex]\frac{n+3}{n+3} -\frac{n}{n+3}[/tex]
= [tex]\frac{n+3-n}{n+3}[/tex]

The square root of [tex]25x^2-40xy+16y^2[/tex] is 5x - 4y.
Given that,
The quadratic equation is [tex]25x^2-40xy+16y^2[/tex].We need to find out the square root.Based on the above information, the calculation is as follows:
[tex]= 25x^2-40xy+16y^2\\\\= (5x)^2 - (2\times 5x \times 4y) + (4y)^2\\\\= (5x - 4y)^2\\\\= \sqrt{ (5x - 4y)^2}[/tex]

Solve using the order of operations. (9+9+72)-4+9
PLZ ANSWER PLZ HURRY
Answers
Answer:
95
Step-by-step explanation:
The order of operations is PEMDAS
Equations in PARENTHESES come first
Numbers with EXPONENTS come second
MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation
ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)
So we do (9+9+72) first
So that equals 90
And then we subtract 4 from 90
90 - 4 = 86
Then we add 9 to 86
86 + 9 = 95

Step-by-step explanation:
Answer:
The answer is -18
Step-by-step explanation:
STEP 1:
[tex]3 \times \frac{2}{3} (x + 6) = 3( - 8)[/tex]
2(x+6) = -24
______________________________________
STEP 2:
Divide both sides by 2:
[tex] \frac{2(x + 6)}{2} = \frac{ - 24}{2} [/tex]
________________________________
STEP 3:
Simplify:
[tex]x + 6 = - 12[/tex]
Subtract 6 from both sides:
[tex]x + 6 - 6 = - 12 - 6[/tex]
________________________________
STEP 4:
[tex]x = - 18[/tex]
Therefore, your answer is -18.

Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20
Answers
Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..
