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:
Step-by-step explanation:
Let's call the initial point and the second point we can find the distance between these two points with the following formula:
And if we replace we got:
So since we know the time in order to reach the point R we can find the velocity like this:
And this velocity is constant along all the displacement.
Let's call the final point
And we can find the distance between the point R and F like this:
And if we replace we got:
Since the velocity is constant we can find the time between point R and F like this:
And we are interested on "When will it pick up the ball located at position (28,35)?" And then the total time would be:
The figure attached illustrate the problem.
Answer: There are 6 phones and 18 accessories sold.
Step-by-step explanation:
Since we have given that
Let number of phones sold be 'x'
Let number of accessories sold be 'y'.
Commission for every phone = $12
Commission for every accessory = $3.50
Total commission = $135
And Difference between accessories and phones sold = 12
According to question, we get that
Using both the equations, we get that
x=6 and y = 18
Hence, there are 6 phones and 18 accessories sold.
