Are babies weight increases by 8% over a month from birth to 4. 5 kg what was the weight at birth

Answers

If babies weight increases by 8% over a month from birth to 4. 5 kg, the baby's weight at birth was approximately 4.17 kg.

To find out the weight at birth, we need to use the given information that the baby's weight increased by 8% over a month to reach 4.5 kg.

Let's start by setting up an equation. We can let x be the baby's weight at birth in kg. Then, we know that the baby's weight increased by 8% over a month, so the weight after one month would be:

x + 0.08x = 4.5 kg

Simplifying this equation by combining like terms, we get:

1.08x = 4.5 kg

To solve for x, we can divide both sides of the equation by 1.08:

x = 4.17 kg

A scientist suggests keeping indoor air relatively clean as follows: provide 2 or 3 pots of flowers for every 100 square feet of floor space under a ceiling of 8 ft. If your classroom has an 8 ft ceiling and measures 35 ft by 40 ft, how many pots should it have?

Answers

First we calculate classroom surface:
35*40=1400 square ft
we know that for every 100 square ft 2 or 3 pots can be put
so 1400/100=14
14*2=28
14*3=42
we need 28 or 42 pots
