PH can be calculated using the following equation
pH = -log [H₃O⁺]
for apple juice the hydronium /hydrogen ion concentration is 0.0003
pH = -log (0.0003)
pH = 3.5
correct answer is C
For ammonia
pH = -log (3.1 x 10⁻⁹)
pH = 8.5
answer should be 8.5
Answer:
Value of the answer (3¹²)
Step-by-step explanation:
Given:
(3⁵)² / 3⁻²
Find:
Value of the question.
Computation:
⇒ (3⁵)² / 3⁻²
⇒ (3¹⁰) / 3⁻²
⇒ (3¹⁰) (3)²
⇒ (3¹⁰⁺²)
⇒ (3¹²)
⇒ 531,441
Value of the answer = (3¹²)
Using the Punnette Square :
R r
<span>R RR Rr </span>
<span>r Rr rr
</span>Hence,
<span>By applying the rules of probability Rr x Rr, the probability of the offspring being homozygous recessive will be one fourth or a quarter.
SO the best is :
B. 1/4</span>
Answer:
a) 
b) 
Step-by-step explanation:
For this case we can use a linear model to solve the problem.
s) Create an equation to express the increase on the price tickets and the number of seats sold
number of seats, if w analyze the info given the number of seats after increase the price is given by
.
And let P the price for the ticket. So after the increase in ticket price the expression for the increase is P-200.
We have an additional info, for each increase of $3 the number of setas decrease 1. And the equation that gives to us the price change in terms of the increase of price is:

So then our linear equation is given by:

b) Over a certain period, the number of seats sold for this flight ranged between 90 and 115. What was the corresponding range of ticket prices?
So for this case we just need to replace the limits into the linear equation and see what we got:


So the corresponding range of ticket prices is:

Answer:
A. =
Step-by-step explanation:
Find a common denominator, then compare.
