Step-by-step explanation:
Given the question:
Find the error in the student's calculation. 2 cubed (2 minus 4) + 5 (3 minus 8). 2 cubed (negative 2) + 5 (5). 8 (negative 2) + 25. Negative 16 + 25. 9.
The student's error occurred here :
2 cubed (negative 2) + 5 (5)
(3 - 8) will give - 5 and not 5 as Witten by the student. The correct working is stated below :
2³(2 - 4) + 5(3 - 8)
Step 1:
8(-2) + 5(-5)
Step 2:
-16 + - 25
Step 3:
-41
Step-by-step explanation:
profit = sold price - bought price
= 140,000 - 60,000 k
= 80,000 k
% profit = (80,000/60,000)×100
= 133.33 %
The area of the triangle is 90 m²
Explanation:
Given that the base of the triangle is 15 m
The altitude of the triangle is 12 m
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,
where b is the base and h is the altitude
Thus, we have,
and 
Substituting the values in the above formula, we get,
Multiplying the terms, we get,
Dividing, we get,
Therefore, the area of the triangle is 90 m²
