1. 3in =5ft, 6in=10ft, 9in=15ft, 12in=20ft, 18in=30ft, 21in=35ft (multiples of 3 for the top row, the bottom row is multiples of 5. when the second column appears 3x2 is 6 and 5x2 is 10, and keep going. whatever number you multiply 3 by is the same number you multiply 5 by.)
a) 30ft
b) Actual is 2.5ft and would be the bottom row. You would divide 5 by 2. Do the same for 3 and it is 1.5in.
2. Scale 2in = 4ft.
The scale dimensions of a room is 14x7
2×x=14 x=7 7×2in=14in. The actual wall would be 7×4=28ft
The scale drawing is 7in. 3.5×2=7in Then 3.5×4=14ft
Final dimensions, 28ft x 14 ft.
3. 2cm = 5m Scale
10cm = 25m. 10cm=2×5. 5m×5=25m
6cm = 15m, 6cm=2×3. 5m×3=15m
Answer:
Solving the inequality
we get 
The graph of the inequality is shown in figure attached.
Step-by-step explanation:
We need to Solve each compound inequality 
Solving the inequalities
For solving compound inequalities we solve both inequalities simultaneously and find the value of m.
For solving 5+m > 4, we subtract 5 from both sides.
While solving 7m < -35, we divide both sides by 7 to get value of m
Applying these functions we get:

So, solving the inequality
we get 
The graph of the inequality is shown in figure attached.
Convert 9 1/2 into a mixed fraction: 19/2.
Now, multiply with 6 which in fraction form is 6/1
19/2 times 6/1 equals 114/2
Now you can divide 114/2 which is 57 inches squared.
Have a good day ! :)
Answer:
its just a black screeeeen
Step-by-step explanation:
4/3 in simplest form is 4/3 but in decimal form it would be 1.33333
