Answer:
Nina's rate is 12.7059 miles per hour (answer rounded up to four decimal places).
Step-by-step explanation:
Nina can ride her bike 63,360 feet in 3400 sec
1 mile = 5,280 feet
How many miles = 63,360 feet ?
Its 63,360 feet ÷ 5,280 feet × 1 mile = 12 miles
Nina's rate is 12 miles per 3400 seconds
1 hour = 3600 seconds
So in 1 hour, Nina rides × 12 miles = 12.7059 miles (rounded up to four decimal places)
Nina's rate is 12.7059 miles per hour (answer rounded up to four decimal places).
To solve the problem, get first the area of the circle and the square -
Circle -> Area = pi * r^2; r= radius
= 3.14 * 1.5^2m^2 (radius is 1/2 of diameter)
= 3.14 * 2.25m^2
= 7.065m^2 or 7.07m^2 when rounded-off
Square -> Area = a^2; a = side
= 3^2m^2
= 9m^2
You can now perform the subtraction process -
9.00m^2 - 7.07m^2 = 1.93m^2
Therefore, 1.93m^2 is the difference between the area of circle and square

Answer:
Possible numbers for Joshua's house are #13 and #21.
Step-by-step explanation:
Given:
Vacation houses are equally spaced along a street.
The first house is marked with #10 and so on.
Maria lives in house marked as #17.
Joshua lives 4 houses away from Maria.
So, the difference between Joshua's house number and Maria's house number is 4.
Let 'x' be the house number of Joshua's house.
Case 1: If Joshua's house is after Maria's house. So,
Case 2: If Joshua's house is before Maria's house. So,
Therefore, the possible numbers for Joshua's house are #13 and #21.
