Answer:
8 hours
Step-by-step explanation:
5 - 1 = 4 grams
10% of 5 = 0.5 grams per hour
4/0.5 = 8 hours
1. 462.25 × 24 × 60 = 665640
2.
3. you have to sub first so
given
x/2 = 7
subtract
x=14
multiplication
Answer:
Step-by-step explanation:
radius r= √{(1-1)²+(2+1)²}=3
area==πr²=3.14×3²=28.26 sq. units.
A is the answer and i am in 6th grade
The first thing you should do in this case is to draw the vertices in the Cartesian plane and join each of the points.
Then, to find the area of the figure you must first find the area of the rectangle and add it to the area of the parallelogram.
Area of the rectangle: Ar = (w) * (l)
Ar = (root ((6-4) ^ 2 + (1 - (- 2)) ^ 2)) * (root ((- 3-6) ^ 2 + (7-1) ^ 2))
Ar = (3.61) * (10.82)
Ar = 39
Parallelogram Area:
Ap = b * h
Ap = (root ((- 7 - (- 3)) ^ 2+ (7-7) ^ 2)) * (root ((- 7 - (- 7)) ^ 2+ (7-4) ^ 2) )
Ap = (4) * (3)
Ap = 12
Total area:
At = Ar + Ap = (39) + (12) = 51
answer: The area of the figure is: At = 51 Units ^ 2
