b. 450.80
you multiply 40 x 9.80 ...equals 392.
<span>take 1/2 of 9.80...that equals 4.90. </span>
<span>4.90 plus 9.80 equals $14.70 x 4 = 58.80 </span>
<span>$58.80 plus 392. equals $450.80</span>
32 kilometers + 35 kilometers + 17 kilometers
= 67 kilometers + 17 kilometers
= 84 kilometers

Answer:
The 2nd root of 10, or 10 radical 2, or the square root of 10 is written as 2√10=√10=±3.162278.

Step-by-step explanation:
Suppose the radius is 1. The parametric equations for the circle are
x = cosθ
y = sinθ
x:y = 3:1
tanθ = ⅓
cosθ = 3/√(1²+3²) = 3/√10
sinθ = 1/√10
The solutions are (3/√10, 1/√10) and (-3/√10, -1/√10).
To find the length and width of 3 different rectangles that have an area of 48 square inches, you can use the factor pairs that result in 48.
The reason is that to find the area of a rectangle you multiply two dimensions.
2 in x 12 in
3 in x 8 in
4 in x 6 in
On all these either one could be the length and the other the width.
