Based on the picture above,
The theorem or postulate that justifies that Angle HEF ~ angle HGE is :
A. AA similarity postulate
(s is used for equal side, that is used for congruent)

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
92 and 35 that the answer
Answer:
9 3/4 > 9.5 > 9 3/8 > 9.125
Step-by-step explanation:
convert the fractions to decimals and put it that way
To solve use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
14 + 18 ÷ 2 x 18 - 7
Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be division first then multiplication.
NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression
Division
14 + 18 ÷ 2 x 18 - 7
18 ÷ 2 = 9
14 + 9 × 18 - 7
Multiplication
14 + 9 × 18 - 7
9 × 18 = 162
14 + 162 - 7
Addition
14 + 162 - 7
14 + 162 = 176
Subtraction
176 - 7
= 169
