pH measures how acidic or basic a substance or solution is. The relevant formula is pH = –log[H+]. To find the concentration of H+, we can manipulate the equation by raising both sides to base 10, resulting in 10^ -pH = H+. Given a pH of 7.2, the concentration is represented as C<span>[H+] = 10^-7.2</span>.

Inessa [12570]

Answer:

5 miles in total

Step-by-step explanation:

Given:

Time spent driving = 10 min = 10 / 60 = 1/6 hour

Duration of stop = 5 min

Driving speed = 30 miles per hour

Find:

Complete distance

Computation:

Distance traveled = Speed × time

Distance = 30 × (1/6)

Total distance = 5 miles

Sharon is 54 inches tall. tree in her backyard is five times as tall as she is. the floor of her treehouse is at a height that i
Inessa [12570]
To resolve this question, we begin by determining the height of the tree. If Sharon measures 54 inches, and the tree is five times her height, the calculation would be 54 times 5, resulting in 270 inches. Next, we find the height of the treehouse floor, which is stated to be twice her height, thus 54 times 2 equals 108 inches. Finally, we need to calculate the difference between the top of the tree and the height of the treehouse floor: 270 - 108 equals 162. I hope this information assists you!:) Best answer?

Tanmay had some chocolates with him. He gave one-third of them to Akash and one-fifth of them to Sharad. Tanmay could do so with
babunello [11817]

Answer:

Possible values for X include;

15, 30, 45, 60, and so on

Step-by-step explanation:

The parameters provided are

Number of chocolates Tanmay possessed = X

Number of chocolates given to Akash = 1/3 × X

Number of chocolates given to Sharad = 1/5 × X

Consequently, since both 3 and 5 divide X,

3 × 5 = 15 is the smallest single factor of X.

Thus, the values of X based on this minimum factor are as follows;

15 × 1 = 15

15 × 2 = 30

15 × 3 = 45

15 × 4 = 60

Therefore, potential values for X form an arithmetic series: a + (n - 1) × d

Where:

a = 15

n = 1, 2, 3, 4,...

d = 15

This results in;

15, 30, 45, 60
