Answer:
A)
,
,
, 
B) 2.53, 32.51, 514.37
Step-by-step explanation:
A) Multiply all of them to equal 80
1/2 = 40/80 (1 x 40) (2 x 40)
2/5 = 32/80 (2 x 16) (5 x 16)
3/8 = 30/80 (3 x 10) (8 x 10)
7/10 = 56/80 (7 x 8) (10 x 8)
B) Decimals are easy 1.10 < 1.20 since one is still greater than the other.
Answer:
210 sq in
Step-by-step explanation:
Box dimensions: 5 x 5 x 8
2 faces: 5 x 5 -> 2 * 5 * 5 = 50
4 faces: 5 x 8 -> 4 * 5 * 8 = 160
Total = 50 + 160 = 210 sq in
Answer:
-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)
10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)
Step-by-step explanation:
-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)
10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)
Divide the amount of gravel in the 5/6 pound mixture:
1/4 / 5/6 = 1/4 * 6/5 = 6/20 = 3/10 pounds
