Ratio s 3:8
other one is x:12
3:8=x:12
3/8=x/12
times both sides by 12
36/8=x
4 and 4/8=x
4.5=x
4 and 1/2=x

Answer:
x = 1
Step-by-step explanation:
Given in the question the equation
y = -x² + 2x - 1
To find the x-intercept, substitute in 0 for y
0 = -x² + 2x - 1
To find value of x use quadratic equation
x = -b ± √b²-4ac / 2a
here a = -1
b = 2
c = -1
x1 = -2 + √2²-4(-1)(-1) / 2(-1)
= -2 + 0 / -2
= -2 / -2
= 1
x2 = -2 - √2²-4(-1)(-1) / 2(-1)
= -2 - 0 / -2
= -2 / -2
= 1
We will find out 7% of 25.
7/100*25
=1.75 %
Therefore, 1.75% of Janie's class has blue eyes.
HARRY POTTER FOREVER! : P
We can work out the circumference of the wheel by using the equation
C = πd
C = π × 2
C = <span>6.28318530718
C = 6 feet
If 1km is 3280 feet, 2km is 6560 feet
6560 </span>÷ 6 = <span>1093.33333333 (recurring)
= 1093
Therefore the bike wheels rolls (approximately) 1093 times to cover 2km.
