height of water = 6.25 cm
The volume of the container = 20 × 10 × 10 = 2000 cm³
volume after 750 cm³ is poured out = 2000 - 750 = 1250 cm³
height = 1250/( 20 × 10) = 6.25 cm
The inputs are -3, -4, 8, and 7
Answer:
OPTION B) 2ab
Step-by-step explanation:
Given:
Side of larger square = (a + b) units
Side of smaller square = c units
To Find:
The area of all four triangles combined = ?
Solution:
a^2 + b^2 = c^2 (Pythagoras theorem) -(1)
The area of all four triangles combined = Area of larger square - Area of smaller square
The area of all four triangles combined = (a + b)^2 - c^2
The area of all four triangles combined = a^2 + b^2 + 2ab - (a^2 + b^2) {By (1)}
The area of all four triangles combined = a^2 + b^2 + 2ab - a^2 - b^2
The area of all four triangles combined = a^2 - a^2 + b^2 - b^2 + 2ab
Therefore, The area of all four triangles combined = 2ab sq. units

Answer:
Step-by-step explanation:
We are given the following in the question:
Let l be Lyle's height, h be Harry's height and v be Vince's height.
Thus, we can write:
Lyle's Height =
Harry's height =
Putting the value in the equation:
Thus, Vince's height is 3.5 feet.
You devide by 4 and it is 21 over 25
