Answer:
Lines BC and F represent perpendicular lines
Step-by-step explanation:
we have
<em>Line BC</em>
the slope of the line BC is 
<em>Line F</em>
the slope of the line F is 
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so
we have
-----> slope line BC
-----> slope line F
Find the product of their slopes
therefore
Lines BC and F represent perpendicular lines
Answer:
1.1 R5.83
1.2 R70.01
1.3 58.34%
Step-by-step explanation:
Given that he buys a pack of 12 racing cars for R49,99 then the unit cost for a car which is the total cost divided by the number of cars in a pack
= R49,99/12
= R4.17
If each car is sold for R10 then the profit made on each car which is the difference between the cost and the selling price
= R10 - R4.17
= R5.83
The profit margin on one pack of 12 racing cars
Profit margin is the ratio of the profit to the total selling price
The total profit (profit on one pack of 12 racing cars)
= R5.83 * 12
=R70.01
Total selling price = R10 * 12
=R120
Margin = R70.01 / R120
= 58.34%
Answer:
10.67% increase
Step-by-step explanation:
We can find percent increase with (difference/original) x 100
7.47 - 6.75
= 0.72 (difference)
(0.72/6.75) x 100
= 10.67% increase
Fist subtract 5 from both sides
Equation is now 2s is greater than or equal to 44
Now divide by 2
Equation is now s is less than or equal to 22
Be sure to flip equality sign when dividing
