Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
If the decimal is moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
<u><em>Answer:</em></u>
Mrs. Hong originally had 900 ml of milk
<u><em>Explanation:</em></u>
The complete question is in the attached image
Assume that the amount of milk Mrs. Hong originally had was x ml
<u>We are given that:</u>
1- She used 
of it to bake the waffles, <u>therefore</u>:
Amount used in baking waffles = 
ml
2- She used 300 ml to bake a pie
3- Amount left is half the original amount, <u>therefore</u>:
Amount left = 
ml
<u>We know that:</u>
Total amount = amount used in waffles + amount used in pie + amount left
<u>Substitute with the givens and solve for x:</u>
Total amount = amount used in waffles + amount used in pie + amount left
<u>This means that:</u>
She originally had 900 ml of milk
Hope this helps :)
We need to work out first the scale factor of the side length
Side MN correspond to the side JK
Side MN = 3.5 cm
Side JK = 14 cm
Scale factor = 14/3.5 = 4
Side OM correspond to side LJ
Side OM = 12 cm
Side LJ = 12 × 4 = 48 cm
The volume of the cylinder with an hexagonal base is 1793.4 cm³
<h3 /><h3>How to find the volume of a cylinder?</h3>
The volume of a cylinder with a hexagonal base can be found as follows;
volume of the hexagonal cylinder = Bh
where
Therefore,
area of the hexagonal base = 1 / 2 pa
where
- p = perimeter
- a = apothem
Therefore,
Volume = (0.5 × 6.1 × 7 × 6) × 14
Therefore,
volume = 128.1 × 14
volume = 1793.4 cm³
