Find the area of the triangle that has a base of 5 in. and a height of 3 and 3/4 in.
2 answers:
The formula for area of a triangle given its base and its height is A = (bh)1/2.
The base and height of the triangle are given as follows.
b = 5
h = 3 3/4 or 15/4
Plug these values into the above formula and solve.
A = (bh)1/2
A = 5(15/4)1/2
A = 75/4 * 1/2
A = 75/8
Answer:
The area of the triangle is in² or
in².

Step-by-step explanation:
Given
Variation: inverse Proportion
y = 7, x = 9
Required
- Write an equation connecting y and x
- Find y when x = 21
Given that thee variation is inversely proportional;
This implies that
Convert variation to equation
----------- Equation 1
Where k is the constant of variation
Substitute 7 for y and 9 for x in equation 1
Multiply both sides by 9
Substitute 63 for k in equation 1
Multiply both sides by x
Hence, the equation connecting x and y is
Solving for when x = 21
Substitute 21 for x in the above equation
Divide both sides by 21
