<u>Step-by-step explanation:</u>
A good example that comes to find is the fuel gauge found on a car, this gauge allows the driver to monitor the percentage of fuel left in the car.
Let's assume the car fuel tank has a capacity of 100 liters. if the indicator is showing half-filled, to illustrate this in percentage it is written as 50% while decimal it will be 0.5.
Answer:
223.5 in²
Step-by-step explanation:
The surface area of a triangular pyramid comprises:
- Area of the <u>base triangle</u>.
- Area of 3 <u>congruent side triangles</u>.
<u />
<u>Area of a triangle</u>
where:
From inspection of the diagram:
- Base triangle: b = 10 in, h = 8.7 in
- Side triangles: b = 20 in, h = 12 in
Therefore, the surface area of the given triangular pyramid is 223.5 in².
(6 x 5) x 10 = (30) x 10 = 300
So you would have two zeroes. :)
<span>(5x+9)^2
= (5x)^2 + 2 (5x) (9) + 9^2
= 25x^2 + 90x + 81
