When 448 is rounded to the nearest tens then the value is 450.
When rounding a number to the nearest tens, we consider the digit in the tens place.
In the case of 448, the digit in the tens place is 4.
To round to the nearest tens, we examine the digit in the ones place, which is 8. Since 8 is greater than or equal to 5, we round the tens place up by 1.
Therefore, the digit in the tens place becomes 5, and all the digits to the right of the tens place become zeros.
This gives us the rounded value of 450.

To find the rate of change, also known as the slope, we can use the slope formula with these two given points.
Point 1: (20, 25)
Point 2: (50, 40)
(40 - 25) / (50 - 20)
15 / 30
0.5
The rate of change of this function is $0.50 / lb.

Answer:
$79 million
Step-by-step explanation:
The total of interior angles of a polygon is found using the formula 180 x (n-2) where n is the number of sides.
The above figure has 7 sides, so the total of the interior angles is: 180 x (7-2) = 180 x 5 = 900 degrees.
Find X:
Total all angles: 2x+4x+4x+4x+4x+2x+10x = 900
30x = 900
X = 900/30
x = 30
Angle A = 2x = 2*30 = 60 degrees
The answer is A.
C. 84*
