we are given the function adn we can see that when t is increased, P(t) is decreasing because of the negative sign. This means the value of the population which is the original of 64 billion will have to decrease.The answer that makes sense here is D. D. In 1990, there were 5.33 billion people.
Answer:
56 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(a + b)
where h is the perpendicular height and a, b the parallel bases
here h = 4, a = 5 + 9 + 5 = 19 and b = 9, thus
A = × 4 × (19 + 9) = 2 × 28 = 56 cm²
Answer:
$25
Step-by-step explanation:
Given that:
Cost of Ashley's dinner in Bloomington = $20
Sales tax = 10%
Tip = 15% on $20
To find:
Total cost of the meal ?
Solution:
Let us find the sales tax first of all.
Sales tax is 10% of the total bill.
Therefore, sales tax = 10% of $20
Tip left is 15% of the total bill.
Therefore, tip = 15% of $20
Now, total cost of the meal = Food cost + Sales tax + tip
Total cost of the meal = $20 + $2 + $3 = <em>$25</em>
