No, six eighths (6/8) is not greater than four fourths (4/4). In fact, six eighths simplifies to three fourths (3/4), which is less than four fourths, equal to one. Thus, 6/8 is less than 4/4.

How many permutations exist of the letters a b c taken THREE at a time?

To find the number of permutations of the letters a, b, and c taken three at a time, we use the formula for permutations, which is ( n! / (n - r)! ), where ( n ) is the total number of items, and ( r ) is the number of items to arrange. Here, ( n = 3 ) (the letters a, b, and c) and ( r = 3 ). Thus, the calculation is ( 3! / (3 - 3)! = 3! / 0! = 6 / 1 = 6 ). Therefore, there are 6 permutations: abc, acb, bac, bca, cab, and cba.

What values are greater than 0.5?

Mr Hoffman a science teacher drove 10 miles to school in 20 minutes He drove the 10 miles home in 30 min His average velocity was ms?

To find Mr. Hoffman's average velocity, we first calculate the total distance and total time. He drove 10 miles to school and 10 miles home, totaling 20 miles. The total time taken was 20 minutes to school plus 30 minutes home, which is 50 minutes or 50/60 hours (approximately 0.833 hours). The average velocity is then total distance divided by total time: 20 miles / 0.833 hours ≈ 24 mph, which is approximately 10.7 m/s.

When did the price of money change into pounds and pennies?

The price of money in the United Kingdom changed to pounds and pennies with the introduction of the pound sterling in the 8th century, during the reign of King Offa of Mercia. The system was further standardized in the 14th century, specifically with the establishment of the "pound" as a unit of account and the division of the pound into 20 shillings, each consisting of 12 pennies. This system remained in place until decimalization in 1971, when the pound was redefined as 100 new pence.

How much Fertilizer covers 2500 square feet of lawn find how many bags of fertilizer should be purchased to cover a rectangular lawn 410 feet by 65 feet?

To determine how many bags of fertilizer are needed for a lawn that is 410 feet by 65 feet, first calculate the area of the lawn: 410 feet × 65 feet = 26,650 square feet. If one bag covers 2,500 square feet, divide the total area by the coverage per bag: 26,650 ÷ 2,500 = 10.66. Since you can't purchase a fraction of a bag, you'll need to round up to 11 bags of fertilizer to cover the entire lawn.
