Step-by-step explanation:
a sphere is a 3d circle it not only has a diameter but a circumfrance, height and volume
Answer:4
Step-by-step explanation:
Simplify what you can which is 0.1m-1.3m
you end up getting -1.2m
Now do the other side of the equation which is 2.1-2.7 which is -4.8
Divide -4.8 by -1.2 to get m=4
The perimeter is 12 and the area is 9
Answer:
y=x+3
(0,3)(1,4)
y=x+2
(0,2)(1,3)
Step-by-step explanation:
- For Y=X+3 it could be any point for Y as long as X is 3 less than Y.
- For Y=X+3 it could be any point for X and long as Y is 3 more than X.
- For Y=X+2 it could be any point for Y as long as X is 2 less than Y.
- For Y=X+2 it could be any point for X and long as Y is 2 more than X.
Answer:
The scale factor is k = 1/30
a)
<u>The length of the wing on the model:</u>
- 9 m * 1/30 = 900 cm * 1/30 = 30 cm
b)
<u>The area of the tail section of the plane:</u>
- 80 cm² : (1/30)² =
- 80 cm² * 900 =
- 72000 cm² =
- 72000 * (1/100)² m² =
- 7.2 m²
