It is approximately -.4048
H=10^(-pH)
log H = -pH
pH=-logH => so it is affirmed that it is -.40
Answer:
A
Step-by-step explanation:
the standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
obtain (5 + x)(5 - x) = 7 in this form by expanding the factors
25 - x ² = 7 ( subtract 7 from both sides )
18 - x² = 0 ( multiply through by - 1 )
x² - 18 = 0 ← in standard form
with a = 1, b= 0 and c = - 18 → A
Answer:
I am sick
Step-by-step explanation:
Answer:
$42.02
Step-by-step explanation:
15% discount therefore if you want to find the original price it would be 100% plus 15% = 115%
Multiply the percentage (convert to decimal first) with the discounted value:
1.15(36.54) = 42.021
I think you meant to write
3/4W = 9
to get rid of the denominator, multiply both sides by the denominator.
3W = 36
now divide both sides by 3
W = 12
the answer is 12 ounces.
