Answer:
Step-by-step explanation:
You had the first part of the first question correct. The answer is 100:64
The sides of the squares
Area of e = 69% more than area of area of f
e^2: f^2 = ( 1 + 69/100 ) / 1
e^2 : f^2 = (1.69)/1 Take the square root of both sides
e:f = 1.3:1
Answer:
the temperature dropped 5 degrees in four hours
Step-by-step explanation:
a. 202.5g
Since 45% of the energy drink is sugar
⇒ 45% of the total 450 grams will be made up of sugar
∴ sugar =
* 450
= 202.5g
Thus, the can contains 202.5g of sugar
b. 3.2L
Since Simon used up 20% of the paint, the paint left in the can will now be 80% of the original 4 liters
∴ paint left =
* 4
= 3.2L
Thus, the can has 3.2 liters of paint left.
c. 1680 acres
Here, 30% of the farmer's crop is and the rest is wheat
⇒ 70% is wheat
Total acres of land planted= 2400
∴ Acres planted with wheat =
*2400
= 1680 acres
Thus 1680 acres is planted with wheat
