Answer:
38.2 %
Step-by-step explanation:
120/100 = 1.2 (average time)
(1.2 - 1.5)/1 = -.3
z table value for "-.3" is .3821
<span>x^2+15=8x
</span><span>x^2-8x=-15
x^2 - 2 (x)(4) =-15
adding 16 on both sides
</span>x^2 - 2 (x)(4) +16=-15+16
x^2 - 2 (x)(4) + 4^2= 1
(x-4)^2=1
taking square root on bothsides x-4 = +-1
so x-4=1 or x-4=-1
x-5 or x=3
Answer:
m∠2 = 30°
Step-by-step explanation:
Lines AD and BF are perpendicular, so m∠BOD = 90°
m∠1 + m∠2 = 90
plug in given value:
60° + m∠2= 90°
m∠2 = 30°
