Let a be an apple, b be a baseball, p be a pineapple and s be a shoe.
Then, from the balance, we model these equations:
p + b = s ----- (1)
2s = 4a
Divide both sides by 2.
s = 2a
Substitute in (1), we get,
p + b = 2a ----- (2)
Also,
p = a + b ----- (3)
Substitute the above in (2), we get,
(a + b) + b = 2a
a + 2b = 2a
Subtract a from both sides.
a = 2b
Substitute in (3), we get,
p = 2b + b = 3b
Hence, 3 baseballs equal one pineapple.
Answer:
Step-by-step explanation:
ok. We are given the following equation:

Where:

Since we are asked to determine "H" we will solve for "H" in the equation. To do that we will first multiply both sides by -1:

Now, we will use the following property of logarithms:

Applying the property and having into account that:

We get:

Now we substitute the given value of "pH = 4.5":

Solving the operation:

Therefore, the hydrogen ion concentration of the fluid is 0.000032
He saves $1253 per month.
Explanation: 65% of $3580 is $2327, meaning he spends $2327 per month. He has $1253 left over because $3580-$2327=$1253.
Answer:
Area = 55 cm2
Step-by-step explanation:
It the base of the parallelogram was 9 centimeters and increased by 2, the new base has 9 + 2 = 11 centimeters.
It the height of the parallelogram was 4 centimeters and increased by 1, the new base has 4 + 1 = 5 centimeters.
Now, we can calculate the area of the parallelogram using the formula:
A = b * h
Where A is the area, b is the base and h is the height. So:
A = 11 * 5 = 55 cm2
