Mathematics
Species A: 18.9 miles / 42 minutes = 0.45 miles per minute
Species B: 20.3 miles / 58 minutes = 0.35 miles per minute
Therefore, species A is faster and flies at a speed of 0.45 miles per minute
(27 mph)
0.45 x 60 = 27 mph

The answer is in the image

Mathematics

Cost of 7 gallons=\$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be \$52.5

Mathematics

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=\$53

Therefore, Value after 19 years=\$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

=4300/3.3

=1303.03kg

Area of rectangle= L*b

here,

L=12.4 cm

b= 8.8 cm

A= L*b

= 12.4 * 8.8 = 109.12 cm^2
