Answer:
390 ft^2
Step-by-step explanation:
We will break this shape into two rectangles, one that is 7 ft wide by 30 ft long
and the other that is 25ft-7ft wide by 30ft -20 ft long (18 ft by 10 ft)
1st: 7 ft by 30 ft
A = l*w = 7*30 = 210 ft^2
2nd: 18 ft by 10 ft
A = l*w = 18 * 10 = 180 ft^2
Add the areas together
210+180 = 390 ft^2
The mass of cocoa contained in a chocolate bar of mass 73 grams is: (73 x 54) / 100 = 39.42 grams
Step-by-step explanation:
Px^2+6x+1=x^2+x^2+Qx+1
P=2 and Q=6
Next, 3x^2-5-(x^2-6x+R/2)=2x^2+6x+1
2x^2-5-R/2+6x=x^2+6x+1
-5-R/2=6, R=-22

Answer:
About 11 cups of rice
Step-by-step explanation:
We have 2 1/2 kg of rice. Or we can say 2.5 kg of rice.
Since we want cups and cups is given with ounces (oz), we need to convert the kg amount to ounce amount, first.
We know:
1 kg = 35.274 oz
So, 2.5 kg is:
2.5 * 35.274 = 88.185 oz
Since 1 cup is 8 oz, 88.185 oz is how many cup??
That would be:
88.185/8 = 11.02 cups
Rounded, that is about 11 cups of rice
