A medical researcher stores lab materials in a freezer. To make sure materials are properly frozen and safe to use for their work, the freezer must stay within 5 degrees of the ideal temperature of 18 degrees Fahrenheit. Several times a day a lab manager checks the freezer display to make sure the materials are being stored at a safe temperature. Decide if the following temperatures are safe for the researcher's work. Write Yes if the temperature is acceptable, and No if the temperature is not safe.

step-by-step e

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

thats one
