To find what percentage one number is of another; divide the first number by the other number and multiply by 100 !
p = ( 6 / 76 )× 100 ;
p = 600 / 76 ;
p = 7.89 ≈ 8 ;
p% = 8% ;
<u>Answer:</u>
<h2>1. a</h2><h2>2. b</h2><h2>3. b</h2><h2>4. b</h2><h2>5. 22</h2>
<u>Explanation:</u>
1.
n²-49=0
n=√49
n=7
2.
x²+64=0
x=√64
x=8
3.
if A=144x²
l = √A
l = √(144x²)
l = 12x
4.
b = (24×2)/3b
b = 48/3b
b = 16/b
b² = 16
b = √16
b = 4 in <em>(-4 is correct in algebra but there's no negative lengths in geometric shapes)</em>
5.
x²+z = 103
x² = 103-z
x = √(103-z)
for x = -9 and 9 (103-z) must equal 81
z = 103 - 81 = 22
x = √(103-22)
x = √81
x = -9 , 9
The standard equation of a line is given by:
y = mx + b
Where,
m: slope of the line
b: intersection with the y axis.
To define the linear function you need to know the value of the constants m and b
Answer:
You need in order to find an equation:
Slope of the line
Cutting point with the y axis
