A.
To find a percentage of something, multiply by it's decimal. so 15% is 0.15
In c - 0.15c Louisa is taking the normal cost of a movie subscription and subtracting 15 percent of it off. hence the 15% discount.
We can rewrite this by skipping the subtraction part. If she's getting a 15% discount, you could say she is only paying 85% of it's normal price (100% - 15%). so put 85% in decimal and get 0.85c
Both expressions involve the same discount and both show that she is paying less than full price.
B.
They tell you the width is 16 feet. The length is 4% more than that. in other words the length is 104% the width. In decimal 100% is 1 and 4% is 0.04; 1 + 0.04 is 1.04.
1.04 * 16 = 16.64, which is the length.
Area (assuming the room is a rectangle) is length * width. so 16 * 16.64 whatever that equals is your area.
Answer:
290 centimetres
Step-by-step explanation:
The ratio of the length of the pieces of wood is 6 : 10 : 12.
We have to find the total ratio first:
6 + 10 + 12 = 28
The longer piece of wood has ratio 10.
The length of the original wooden plank is 812 centimetres, therefore, the length of the longer piece of wood is:
10/28 * 812 = 290 centimetres
In geometry proofs, we commonly use step-by-step logic to figure out the proof. This is commonly used in Computer Science for understanding how computers work, process, and store information(I speak from personal experience). This is also commonly used in Law. You use this in Law as a lawyer to deduce information using step-by-step logical processes and logic, otherwise it's just wishful thinking. So, Law also uses the same reasoning skills used in Geometry proofs.
