Answer:
x = 18[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 9² = 27²
x² + 81 = 729 ( subtract 81 from both sides )
x² = 648 ( take the square root of both sides )
x = [tex]\sqrt{648}[/tex] = 18[tex]\sqrt{2}[/tex] ← exact value
x ≈ 25.5 ( to 1 dec. place )

or a faster way to solve these is just 150 (total # of students) and multiply by the percent in decimal form which in this case would be 0.80 (because percentage is out of 100, 80% is 80/100, which is 0.80 as a decimal)

Which of the following equations has no solutions?
A) 2x – 6 = 2x + 8
B) 4x – 8 = 10
C) 5x + 20 = 5x + 20
D) 9x = 9
Answers
Answer: I did the math in my head and I think it’s B
Step-by-step explanation:
2x - 6 = 2x + 8
Just looking at this, it doesn’t make sense. Two times a number - 6 cannot equal two times the same number +8.
But solving it mathematically, we want to get the variables on one side of the equation, so we subtract 2x from both sides:
2x - 2x -6 = 8
Then add 6 to both sides:
2x - 2x = 14
0 = 14 is untrue.
The other options’ answers:
B: x = 4.5
4x - 8 = 10
4x = 18
x = 4.5
C: has an infinite number of solutions. Anything you plug into x on one side of the equation you will plug in on the other side. Both sides are identical.
D: x = 1

x + y = 16
5x - 4y = 12
Answers
Answer:
x = 8.44, y = 7.56
Step-by-step explanation:
x + y = 16 (equation 1)
5x - 4y = 12 (equation 2)
(x + y = 16)× 5
(5x - 4y = 12) × 1
9y/9 = 68/9
y = 7.56
Substitute the value of x in equation 1
x + 7.56 = 16
x = 16 - 7.56
x = 8.44
Therefore, x = 8.44, y = 7.56
Answer:
x = 76 / 9 [ 8 (4 / 9) = [tex]8.\bar{4}[/tex] ]
y = 68 / 9 [ 7 (5 / 9) = [tex]7.\bar{5}[/tex] ]
__________________
Step-by-step explanation:
There are several methods that can be used to solve systems but in this situation, it is generally easier to cancel out a variable by adding the system of equations together.
This is how it's done:
x + y = 16
5x – 4y = 12
__________
4 ( x + y = 16 )
+ 5x – 4y = 12
[Multiplying the entire equation by 4 to cancel out the y because 4y – 4y = 0]
___________
4x + 4y = 64
+ 5x – 4y = 12
__________
9x = 76
÷9 ÷9
[Dividing by the coefficient of 9x in x to get x]
______
x = 76 / 9.
_______
Now that we have the x variable, you can simply substitute that quantity into x + y = 16 to solve for y.
So:
x + y = 16
[substituting the value of x into the equation]
(76 / 9) + y = 16
[Creating a common denominator that
can be canceled out]
(76 / 9) + (9y / 9) = (144 / 9)
76 + 9y = 144
[Subtracting 76 from both sides to isolate 9y]
–76 –76
__________
9y = 68
÷9 ÷9
[Dividing both sides by the coefficient of 9y in y to get y]
_________
y = 68 / 9
_________
We can also verify that these variables have the correct value because:
x + y = 16
5x – 4y = 12
→
(76 / 9) + (68 / 9) = 16
5(76 / 9) – 4(68 / 9) = 12
__________________
(76 + 68 / 9) = 16
(380 / 9) – (272 / 9) = 12
___________________
144 / 9 = 16
(380 – 272 / 9) = 12
__________________
144 / 9 × 9 = 16 × 9
108 / 9 = 12

0/1 For positive integer n, n? = n! · (n − 1)! · … · 1! And n# = n? · (n − 1)? · … · 1?. What is the value of 4# · 3# · 2# · 1#?
Answers
Answer:
331776
Step-by-step explanation:
Since n? = n! · (n − 1)! · … · 1! And n# = n? · (n − 1)? · … · 1?
Then 4# = 4? · (4 − 1)? · (4 − 2)?· 1?
= 4? · 3? · 2?· 1?
Now, n? = n! · (n − 1)! · … · 1!
So, 4? = 4! · (4 − 1)! · (4 − 2)! · 1! = 4! · 3! · 2! · 1! = 288
Thus, 3? = 3! · (3 − 1)! · 1! = 3! · 2! · 1! = 12
Also, 2? = 2! · (2 − 1)! · 1! = 2! · 1! · 1! = 2
and 1? = 1! · (1 − 1)! · 1! = 1! · 0! · 1! = 1
So, 4# = 4? · 3? · 2?· 1? = 288 × 12 × 2 × 1 = 6912
We now find 3#
3# = 3? · (3 − 1)? · 1? = 3? · 2?· 1?
Now, n? = n! · (n − 1)! · … · 1!
So, 3? = 3! · (3 − 1)! · 1! = 3! · 2! · 1! = 12
Thus, 2? = 2! · (2 − 1)! · 1! = 2! · 1! · 1! = 2
and, 1? = 1! · (1 − 1)! · 1! = 1! · 0! · 1! = 1
So, 3# = 3? · 2?· 1? = 12 × 2 × 1 = 24
We now find 2#
2# = 2? · (2 − 1)? · 1? = 2? · 1?· 1?
Now, n? = n! · (n − 1)! · … · 1!
So, 2? = 2! · (2 − 1)! · 1! = 2! · 1! · 1! = 2
1? = 1! · (1 − 1)! · 1! = 1! · 0! · 1! = 1
So, 2# = 2?· 1? = 2 × 1 = 2
We now find 1#
1# = 1? · 1? = 1? · 1?
Now, n? = n! · (n − 1)! · … · 1!
So, 1? = 1! · (1 − 1)! · 1! = 1! · 0! · 1! = 1
And, 1# = 1? · 1? = 1 × 1 = 1
So, 4# · 3# · 2# · 1#? = 6912 · 24 · 2 · 1? = 331776
Mr. Tajpuriya paid Rs 6,780 for a television with a discount of 20% including 13% VAT.what is the marked price of the television?
Answers
Answer:
I'm not really sure about the marked price but you could choose between these
Step-by-step explanation:
6780×13=881.4
6780-881.4=R5898.6 (the price with out the VAT)
6780×20%=1356
6780-1356=R5424 (the price with out the discount)
6780-1356-881.4=R4542.6 (the price without the discount and VAT)
What is this number rounded to the nearest whole number
Answers
The first value behind the decimal point is 0.
When rounding if the value is 0-4 then the value you are rounding to remains the same.
If the value is 5-9 then the value would round up.
However, because it is a 0 it remains a 9.
