On the first visit to the veterinarian's office, Cora's kitten weighted 550 grams.
tamaranim1 [39]

old (first visit): 550 grams

second visit: gained 350 grams

third visit: gained 300 grams

new: cora's kitten is now 1200 grams.

-> now, we must find the percent increase between 550 and 1200.

to find percent increase, we use this equation

new - old / old x 100

-> (1200 - 550 / 550) x 100

   (650 / 550) x 100

   = 1.18 x 100

 <u>percent increase: 118% </u>

<u></u>

✧ hope this helped!

The diameter of a circle is 3.2 meters. Which is the circumference of the circle rounded to the nearest hundredth of a meter?
Paraphin [41]

Answer:

10.05 meters

Step-by-step explanation:

If the diameter is 3.2 meters, then the radius is 1.6 meters.

Use the circumference formula, C = 2\pir, and solve for C

C = 2\pir

C = 2\pi(1.6)

C = 3.2\pi

C = 10.05

So, to the nearest hundredth of a meter, the circumference is 10.05 meters
