An old cell phone battery would last for 16 hours. The new battery lasts 25% longer. How long will the new battery last?​

20 hours

Step-by-step explanation:

To find the answer, you first should find out how long is 25% of the original battery life, 16 hours. To find this, you can divide 16 by 4, or multiply 16 by 0.25. Either works.

16/4=4.

So the new battery lasts 4 hours more than the old battery. Then, add this to the original length to find how long the new battery will last in total.

16+4=20

14

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
