Common denominator would be 40, 3/4 becomes 30/40, 1/5 becomes 8/40, 5/8 becomes 25/40. 10 30/40 + 6 8/40 + 12 25/40 = 28 63/40 = 29 23/40
Answer: $15.94
Step-by-step explanation:
You divide 23.91 by three, then subtract using the previous answer which was 7.97. 7.97 was 1/3 of 23.91. When subtracted you get, 15.94.
Answer:
The correct answer is option A. Base = 11 cm and height = 13 cm
Step-by-step explanation:
It is given that, height of a triangle is 2 cm more than its base.Then height is increased by 2 cm.Then the area of triangle becomes 82.5 cm²
<u>To find the base an d height of original triangle</u>
Let x be the original base 'b' then the height h = x + 2
New height h = x + 2 + 2 = x + 4
Area = bh/2
82.5= (x(x + 4)/2
165 = x² + 4x
x + 4x - 165 = 0
Solving we get x = 11 and x = -15
Take positive value x = 11
Therefore base = 11 and height = x + 2 = 13 cm
The correct answer is option A. Base = 11 cm and height = 13 cm
