Answer:
1.1 mph
Step-by-step explanation:
Step one:
John swims a distance of 5/12 miles
time taken = 3/8 of an hour
Required
The speed with which John swims
Step two:
speed= distance/time
substituting we have
speed= 5/12/3/8
multiply the numerator by the inverse of the denominator
speed= 5/12*8/3
speed= 40/36
speed= 1.1 mph

Step-by-step explanation:
625 = 25*25 = 25^2
=5*5 *5*5 = 5^4
Answer:
7a^4 +35a^2 +28a
Step-by-step explanation:
Area is the product of height and width:
area = height × width
= 7 × (a^4 +5a^2 +4a)
area = 7a^4 +35a^2 +28a . . . . . . use the distributive property
You would have to multiply 0.500(0.5) to 45 and you would get 22.5
