Give the answer <br> the areaaaaaa
GalinKa [24]

Answer:

16

Step-by-step explanation:

The figure shown is a trapezoid

Area of a trapezoid = 1/2(bottom base length + top base length) × height

Bottom base length = 7 units

Top base length = 1 unit

Height = 4 units

So area = 1/2 ( 7 + 1 ) × 4

==> add 7 and 1

Area = 1/2 (8) × 4

==> multiply 1/2 and 8

Area = 4 × 4

==> multiply 4 and 4

Area = 16

A bird leaves its nest and travels 18 miles per hour downwind for 2 hours. On the return trip, the bird travels 3 miles per hour
Darya [45]

Answer:

Step-by-step explanation:

Let y represent the distance travelled downwind by the bird from its nest.

Distance = speed × time

A bird leaves its nest and travels 18 miles per hour downwind for 2 hours. Distance covered in travelling downwind is

2 × 18 = 36 miles

On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after 3 hours. It means that the speed at which the bird travelled is 18 - 3 = 15 mph. Also, the distance covered in 3 hours is 36 - 5 = 31 miles. Therefore,

a) distance of the entire trip is

36 + 36 = 72 miles

b) time spent in travelling downwind from its nest is 2 hours

Time for the return part is

3 hours + 5/15 = 3 + 1/3 × 60 minutes

= 3 hours 20 minutes

Total time for the trip is

2 hours + 3 hours 20 minutes

= 5 hours 20 minutes 0 seconds
