Answer:
1.5ft , B for EDGE2020
Step-by-step explanation:
they are being multiplied by 1.1, so if you divide 1.1 down from 2 three times you get 1.5 roughly.
= [3x3^-2x(-2)^6/2x3^-1x(-2)^5]^2 = 1
Answer:

Step-by-step explanation:
a) The scale 3:24 = 1:8 so if the scale drawing is 5" tall, then the building's actual height is 5×8 = 40 ft.
b) The ratio of the cement to sand is 1:3 so if you have 24 buckets of sand, that means you need 24/3 = 8 buckets of cement.
c) The ratio at which the money is to be distributed is 5:2:4:3. So the money is to be partitioned into 14 (=5+2+4+3) parts so that A get (5/14) of the money, B gets (2/14), C gets (4/14) and D gets (3/14). If C gets R1000 more than D then we can write
Solving for M, which is the total sum of money, we get
Now that we know how much money is involved we can now solve how much money B gets:
