Answer:
4/21 kilometers per hour
Step-by-step explanation:
Since the tortoise traveled 1/6 kilometers in 7/8 hour we can divide 1/6 by 7 because 7/8 divided by 7 is 1/8 and get 1/42.Once we've done this we can then multiply 1/6 by 8 since 1/8 x 8= 8/8 or 1 hour and get 8/48 which simplifies to 4/21.

Answer:
$85.00
Step-by-step explanation:
7.80 x 7 = 54.6
7.60 x 4 = 30.4
54.6 + 30.4 = 85
A = area of triangle + area of rectangular + half of the circle area
_________________________________
triangle area = 1/2 × base × height
triangle area = 1/2 × 3 × 5 = 15/2 = 7.50
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
rectangular area = length × width
rectangular area = 6 × 5 = 30
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
circle half area = 1/2 × pi × radius^2
circle half area = 1/2 × 3.14 × 3^2
circle half area = 1.57 × 9
circle half area = 14.13
_________________________________
A = 7.50 + 30 + 14.13
A = 51.63 m^2
