Answer: 20 pounds.
Step-by-step explanation:
We know the weight of each flower arrangement (each one weighs 6 2/3 pounds) and the total number of flower arrangaments Isabelle ordered (3 flower arrangements).
To make the calculus easier, we can rewrite the mixed number 6 2/3 as a decimal number:
Divide the numerator 2 by the denominator 3 and add the result to the whole number 6:

If 1 arrangement weighs 6.666 pounds, the total weigth of 3 arrangements can be calculated by multiplying 6.666 pounds by 3:

Wish I could help I’m not good at math
I'm assuming you mean how many mph when you refer to how fast the car was going.
So 300 km = 1.5 hrs
1.) Find the number of km per hour
Since we have the equation 300km = 1.5hr, we can just divide 1.5 (to isolate the number of hours) on both sides.
You should get 200 km = 1 hour
2.) Convert km to miles
To do this, you must know the conversion 1 km = 0.621371192 miles
So to convert 200 km to miles, just multiply 200 x 0.621371192.
You should get 124.274238.
That means the Ferrari drove at a pace of roughly 124 mph :)
The answer to this would be complementary angles.
