11. John is building a wall. When he uses 750 bricks, the wall is 6 metres long and 1.25m high.
John wants the finished wall to be 10 metres long and 1.25 metres high.
How many more bricks does John need to finish the wall?
(Total 3 marks)
Answer:
750 blocks = 6m long
x blocks = 10m long
750×10 = 6x
7500 = 6x
divide both sides by 6
7500/6 = 6x/6
1250 = x
x = 1250
.
. . 1250 blocks are needed to finish the wall of 10m long

What is 106% of = $7.95
Answer:
8.427
Step-by-step explanation:
7.95/x=100/106
(7.95/x)*x=(100/106)*x
7.95=0.94339622641509*x
(0.94339622641509) to get x
7.95/0.94339622641509=x
8.427=x
x=8.427
106% of 7.95=8.427

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 2,5,8,... ?
Answer:
Arithmetic sequence with common difference of 3.
Step-by-step explanation:
Arithmetic sequence:
The difference between consecutive terms is always the same, and this difference is called common difference.
Geometric sequence:
The quotient between consecutive terms is always the same, and this quotient is called common ratio.
In this question:
5 - 2 = 8 - 5 = 3
5/2 = 2.5 different of 8/5 = 1.6
This means that it is an arithmetic sequence with common difference of 3.
