Answer:
11.0
Step-by-step explanation:
Using Pythagoras' identity in the lower right triangle.
let the hypotenuse be x , then
x² = 4² + 9² = 16 + 81 = 97
Within the rectangle, use Pythagoras' identity in the lower right triangle.
let y be the dotted line , then
y² = x² + 5² = 97 + 25 = 122 ( take the square root of both sides )
y = 
≈ 11.0 ( to the nearest tenth )
The dotted line is approximately 11.0 units
1/5 of 20 is $4. So, 20-4=$16 remaining.
3/8 of 16 is $7.50. So, 16-7.50= $8.50 remaining.
2/7 of 8.5 is $2.43. So, 8.50-2.43 is $6.07
Answer: Ken has $6.07 left after all his purchases.
38 + p
He scored 58 points total if she scored 20 in the second half
Adding up the number of the points earned in the first half (38) and the number of points earned in the second half (p) will give you the total points.
If he scored 20 points in the second half of the game, then you can change the expression to:
38 + 20
Because now you know what he scored in both the first half and the second half. Then you can add them together to get the answer of 58
Step-by-step explanation:
1/8 x 8 = 1
3/8 x 8 = 3
1/8 x 8 = 1
3/8 x 8 = 3
