It is 20 because the 5 is in the ones place so the 2 has to be in the 10 place which makes it 20
Perpendicular lines are lines that cross at a 90 degree angle
Lines AB and BC
Answer:
$2326
Step-by-step explanation:
I have $1000 invested in a coin worth $43000. If the coin reaches $100000 how much will I have invested?
To solve the above question, we have:
$43,000 = $1000
$100,000 = x
Cross Multiply
43000 × x = 100,000 × 1000
x = 100000 × 1000/43000
x = $2325.5813953
Approximately = $2326
Therefore, If the coin reaches $100000 you would have invested $2326
Answer:
Gradient of line A = 4
Gradient of line B = -2
Step-by-step explanation:
To solve this question, we will use the formula for gradient passing through two points 
and 
,
Gradient (m) = 
For line A,
Since, line A passes through (3, 6) and (4, 10)
Gradient of line A = 
= 4
For line B,
Since, line B passes through (1, 6) and (2, 4),
Gradient of line B = 
= -2
