Answer:

A. Oxygen

Step-by-step explanation:

Carbohydrates are made up carbon, hydrogen and oxygen. They usually have a hydrogen-oxygen ratio of 2:1, which is the same as water.

An easy way to remember what makes up carbohydrates is to just look at the name:

Carbo = carbon,

hyrdrates = water = hydrogen and oxygen

Suppose y varies directly with x.write a direct variation equation that relates x and y .y=7 1/2 when x=3
SCORPION-xisa [38]

as y varies directly with x, the following equation can be established.

y = a * x


from the condition given by the question, we can know that

7.5 = a * 3

a = 7.5 / 3 = 2.5


thus, we can infer that the equation is

y = 2.5 * x

A retailer allows 15% discount on the Marked price of an electric fan. If a customer pays Rs 2244 with 10% VAT,find the Marked P
Alona [7]

Answer:

2400

Step-by-step explanation:

2244 is the final price. it includes the VAT based on the actual sale price. and that is then actually 15% lower than the originally marked price.

so, let's calculate backwards :

2244 = 100% sale price + 10% VAT = 110%

1% = 2244 / 110 = 20.40

100% (actual sale price) = 20.40×100 = 2040

now, because of the 15% discount, these 2040 are only 85% of the originally marked price.

2040 = 85%

1% = 2040 / 85 = 24.00

100% (the original marked price) = 24×100 = 2400
