Answer: 11/21

Step-by-step explanation: Subtract: 67 - 26 = 6 · 67 · 6 - 2 · 76 · 7 = 3642 - 1442 = 36 - 1442 = 2242 = 2 · 112 · 21 = 1121

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(7, 6) = 42. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 7 × 6 = 42. In the next intermediate step , cancel by a common factor of 2 gives 1121.

hope this helps

Answer:

See below

Step-by-step explanation:

See the attached image. My calculation seems a bit off from what I expected, but the reasoning might help.

The paper is trailing the dropped object and a mark is made every 0.020 seconds. By measuring the difference between the dots and dividing by the time, we can calculate the average speed at the the final 2 locations. The difference in these speeds is due to acceleration, as shown in the calculation.

My result wasn't what is considered correct for Earth's acceleration of gravity, but I offer possible explanations. Please check my calculations.

Answer:

160 yd³ must be hauled
$520 is the cost

Step-by-step explanation:

There are 3 feet in a yard, so the volume of the hole is ...

(45 ft)/(3 ft/yd) × (16 ft)/(3 ft/yd) × (6 ft)/(3 ft/yd)

= (15 × 16/3 × 2) yd³ = 160 yd³ . . . volume to be hauled

The cost is $13/(4 yd³), so the total cost will be ...

($13/(4 yd³)) × 160 yd³ = $520 . . . cost of hauling
