A puppy weighs 4.5 pounds at five weeks and 7.5 pounds at eight weeks what was the percentage increase

66.7%

Step-by-step explanation:

Given that,

Weight in first five weeks = 4.5 pounds

Weight at eight weeks = 7.5 pounds

We need to find the increase in precentage. The percentage increase in any value is given by :

So, the increase in precentage is 66.7%.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

its an acute right triangle
