The formula d = ft can be used to calculate the distance (d) an object travels using its rate of speed (r) and the time it travels (t). Using the formula, which shows the rate the object traveled?

Answers

Answer 1
Answer: In that first sentence, you should have typed d = r * t
Rate would be calculated as:
rate = distance / time

The length of a football field is 100 yard and the width is 53 yard. In the fist game of the season, Jos catches the opening kickoff at the corner of the goal line and runs straight as a string the diagonal length of the field to score s touchdown. The next day, the local paper credits Jos for a 100 yard touchdown run, but how far did he actually run

Answers

Given:
Length = 100 yards
Width = 53 yards
Rectangle shape

Jos ran the diagonal length. So, he formed a right triangle. The length Jos ran would be they hypotenuse.

a² + b² = c² ² where c = hypotenuse

100² + 53² = c²
10,000 + 2809 = c²
12809 = c²
c = √12809
c = 113.18 yards.

Nathan uses 1/18 of a gallon of milk each time he eats a bowl of cereal.Nathan has used 8 gallons of milk for cereal in one year.how many bowls of cereal did he eat?

Answers

Let us assume the total number of bowls of cereal that Nathan has eaten in a year = x

With each bowl of cereal, Nathan has 1/18 gallon of Milk.

In total the number of gallons of mulk in a year = 8 gallons,

Therefore, we frame the equation as shown below to calculate "x"

1/18 * x = 8

x = 18*8 = 144

Number of bowls of cereal Nathan ate in a year = 144 bowls
To do this we would have to do 18×8, which equals 142. 142 bowls of cereal.

Step-by-step explanation:

9. f(g(-n))

g(-n) = -(n²+5) = -n²-5

f(g(-n)) = 2n+1 (-n²-5 )

2n(-n²-5)+1(-n²-5 )

-2n³-10n-n²-5

-2n³-n²-10n-5

n²(-2n-1) +5(2n-1)

(n²+5)(2n-1)
