Here’s the answers for you
8 ft wide, 12 ft long......so if u want it 2 ft wide, u have a scale factor of 1/4.
that means ur length will be 12 * 1/4 = 12/4 = 3 ft long
A = L * W
A = 3 * 2
A = 6 square ft <==
If the spinner is evenly divided then they all have a 25% chance
At rate x miles/ hour drove d miles/ 4 hours;
At rate x-10 miles / hour drove d miles/5 h
d miles = x• 4 miles first rate
d miles= (x-10)•5 miles second rate
5x-50= 4x
5x-4x= 50
X= 50 miles/h to get to the beach
50-10= 40 miles/h to get home
The answer would be f(x)=3.9n+15.85 since every floor is 3.9 meters high you need to multiply 3.9 by the number of floors which in this case would be n. Then you add the height of the antenna because it is included in the measurement. Using the order of operations you would multiply from right to left first which would give you the height of the building without the antenna, then you would add the 15.85 which would give you the total height of the building including the antenna if you would know how many floors there are.
