8×9＝72
5×8＝40
So the answer is 8
Answer:
720
Step-by-step explanation:
because 8% of 9000$ is 720$.
another way.
Step 1: Our output value is 9000.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$9000=100$.
Step 4: Similarly, $x=.8%$.
Step 5: This results in a pair of simple equations:
$9000=100%(1)$.
$x=.8%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
Step 7: Again, the reciprocal of both sides gives
Therefore, 8%of $9000$ is $720
Y+9=1/5x menjadi y= 1/5x -9
sesudah ini sibtusika n dalam persamaan 4x - 5y = -15x
<span> 4x -5(1/5x-9)= -15 x
4x + x+45=-15x
5x +45 = -15x 45=-20x
x=-45/20
x= -9/4
y+9 =1/5x
y = 1/5(-9/4)-9
y = -189/20

Answer:
8 - 2π square units.
π/16 - 1/8 square units.
6π - 9√3 square units.
Step-by-step explanation:
The area of the square = 2√2 * 2√2
= 2*2*2
= 8.
The area of the circle = πr^2
= π * [ ( 2√2)/ 2) ]^2
= π (√2)^2
= 2π.
Second Question:
The area of the circle = π(1/2)^2 = π/4.
Finding the area of the square:
1^2 = 2x^2
x^2 = 1/2
So the area of the square = 1/2
So the area of the red part = 1/4 ( π/4 - 1/2).
= π/16 - 1/8.
Third question
Area of the circle = 6^2 * π = 36π.
Now 60 degrees is 1/6 of 360 degrees so the are of the sector is 6π.
The area of the segment = 6π - 0.5 * 6^2 sin 60
= 6π - 18√3/2
= 6π - 9√3 square units.
Answer:
find 9% of 12
12 times 9 divided by 100
108/100
$1.08
12+1.08
Your mean costs $13.08
