Answer:
- area: 240 ft^2
- bases: 20 ft, 10 ft
- height: 16 ft
Step-by-step explanation:
Apparently, 4/5 of a gallon is used, so covers ...
(4/5)(300 ft^2) = 240 ft^2
The area of the trapezoid is 240 square feet.
__
The short base of the trapezoid is half the length of the longer base, so is ...
(1/2)(20 ft) = 10 ft
The lengths of the bases are 20 ft and 10 ft.
__
The area formula for the trapezoid is ...
A = (1/2)(b1 +b2)h
Filling in the numbers we know, we can find h.
240 = (1/2)(20 +10)h
240 = 15h . . . . . simplify
16 = h . . . . . . . . . divide by 15
The height of the trapezoid is 16 feet.
To find area you do length x width so it would be 25*8 which equals 200 so your area is 200ft
ik=30.5 because 49 - 12 = 37.5 and 37.5/2+12=30.5
Answer:
Step-by-step explanation:
Let the required probability be denoted by P(1A 2A 3B 4B).
This means a shopper chooses brand A first. Then by choosing brand A as the second purchase, the same brand is used. The third purchase is brand B; hence he switches brand. The fourth purchase is also brand B, maintaining the same brand as the third.
On the first purchase, the probabilities of A and B are both equal. Hence, each probability = 1/2
That would be 10001 ( base 2) (answer)
This = 101 (base 4)
They both = 17 in decimal.
