Let
ba--------> area of bases (<span>the two bases included</span>)
p---------> perimeter of the base
h--------> height of the prism
la-------> lateral area
we know that
[surface area]=2*[area of one base]+[perimeter of the base]*height
so
2*[area of one base]=ba
[surface area]=[ba]+[p]*h
and
the formula of lateral area is
[la]=[perimeter of the base]*height
[la]=[p]*h
therefore
[surface area]=[ba]+[la]
the answer is
[surface area]=[ba]+[p]*h
[surface area]=[ba]+[la]
Answer:
n + 6
Step-by-step explanation:
5n - 3 ( n - 2 ) - n
4n - 3 ( n -2 )
4n - 3n - 3 x (2)
4n - 3n - 3 x 2
4n - 3n + 6
n + 6
Answer:
950000
Step-by-step explanation:
the rule with rounding is if the number to the direct left is under 5, it stays the same but if it is 5 or above, you round up and everything behind becomes zeroes.
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - given point
If you wish to<u> mentally estimate</u> the <u>total cost</u> of items, <u>rounding </u>off the items to the<u> nearest half dollar</u>, then you have to consider all five items separately.
Five items cost $1.85, $.98, $3.49, $9.78, and $6.18.
1. $1.85≈$2;
2. $0.98≈$1;
3. $3.49≈$3.50;
4. $9.78≈$10;
5. $6.18≈$6.
Then the total cost is
$2 + $1 + $3.50 + $10 + $6 =$22.50.
