1×10+7×1+6×0.1+0×0.01+1×0.001 is the answer
I don’t really know exactly what you’re asking but if you’re asking what is most practical, it would be #4
1 week = 7 days
1 gallon = 16 cups ⇒ 1 cup = 1/16 gallon
1.5 cups = 1.5 · 1/16 gallon = 15 · 1/160 gallon = 3/32 gallon
1.5 cups per day = 3/32 gallons per day = 7 · 3/32 gallons per week
= 21/32 gallons per week
Answer:
3.777
Step-by-step explanation:
Answer:
A = 4 cm²
Step-by-step explanation:
The area of a triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
b = AC = 3
+ = 4
h = BD
Calculate BD using Pythagoras' identity in Δ ABD
BD² = AB² - AD²
= (2
)² - (3 )²
= 20 - 18 = 2 ( take square root of both sides )
BD =
Then
A = × 4 × = 2 × × = 4 cm²
