in one year dog's weigh from 64 pounds to 80 pounds . by what percentage did the dog's weght increase

Masja [62]

Answer:

15%

Step-by-step explanation:

First, let's find how many pounds the dog's weight increased by during the year.

80 - 64 = 16

Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).

$\frac{16}{64}$ • 100 = 0.25 • 100 = 25%

Select all of the following expressions that are equivalent to 0.25.. . 1. (0.5)2. 2. (-0.2) + (-0.05). 3. |-3 + 2.75|. 4. -(-0.

shepuryov [24]

The solutions for the following expressions are:
1. 0.5*2 = 1
2. -0.2+-0.05= -0.25
3. absolute value of (-3+2.75) = 0.25
4. -(-0.25) = 0.25
5. 2x-1.75x = 0.25x

The expression equivalent to 0.25 is numbers 3 and 4.
