devin began running a month ago to get back in shape.the first day he ran .5 miles. each day after that he ran 10% more than the previous day for a total of 30 days. use the formula for the sum of a finite geometric series to calculate the total distance devin ran over the 30 days.

Answers

Answer 1
Answer: The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))

The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)

S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi

After 30 days, he will have traveled 82.25 miles.

(4 pts) Henry walks out of his hall and proceeds to walk 200 feet due north. He then turns left (west) and walks 190 more feet. Finally, he turns 45∘ left and walks 260 feet. How many feet is Henry from his starting point

Answers

Answer:

Henry is approximately 276 feet from his starting point.

Step-by-step explanation:

To find how many feet Henry is from his starting point, you can use the Pythagorean theorem because he walked in both the north and west directions, creating a right triangle. Here's the calculation:

1. The distance he walked north is 200 feet.

2. The distance he walked west is 190 feet.

3. The 45-degree angle forms a right triangle.

Now, use the Pythagorean theorem:

a² + b² = c²

Where:

a = 200 feet (north)

b = 190 feet (west)

a² + b² = c²

(200)² + (190)² = c²

40000 + 36100 = c²

76100 = c²

Now, find the square root of 76100:

c = √76100 ≈ 276 feet

So, Henry is approximately 276 feet from his starting point.

During practice, the Northwood football team drinks water from a cylindrical cooler that has a radius of 6 inches and a height of 20 inches. Players use conical paper cups, as shown below. A cone has a diameter of 4.4 inches and a height of 5.5 inches. If the water cooler is filled completely, can each of the 38 players have two full paper cups of water during practice? Explain.

Answers

Approximately 81 conical cups can fill. Therefore, each of the 38 players can fill two full paper cups of water during practice.

Given that, the radius of the cylindrical cooler=6 inches and height=20 inches.

The radius of the conical cup=2.2 inches (4.4/2) and height=5.5 inches.

What are the formulas for the volume of the cylinder and the volume of the cone?

The volume of the cylinder =πr²h and the volume of the cone =1/3 πr²h.

Now, the number of paper cups =The volume of the cylinder cooler/ The volume of the conical cup.

The volume of the cylinder cooler =π×6²×20=720π cubic inches.

The volume of the conical cup =1/3 π×(2.2)²×5.5=8.9π cubic inches.

The number of paper cups =720π/8.9 π=80.89

Approximately 81 conical cups can fill. Therefore, each of the 38 players can fill two full paper cups of water during practice.

Tony had 1 1/2 gallons of orange juice. He drank 2/7 of the orange juice he had. How mucj orange juice did Tony drink?

Answers

Answer:

(3)/(7)gallon.

Step-by-step explanation:

Amount of orange juice Tony had  is 1(1)/(2) gallons.

Amount of orange juice drank by him is (2)/(7) of the orange juice he had.

To find the amount of orange juice Tony drink, we need to first convert the amount of orange juice Tony had in improper fraction, as the amount of juice he had is given in Mixed fraction.

So, amount of orange juice Tony had is 1(1)/(2) =(3)/(2) gallons.

Now, to find the amount of orange juice Tony drink, we need to multiply (3)/(2) and (2)/(7)

So, amount of juice Tony drink is (3)/(2)* (2)/(7)

=(3)/(7)

Hence, amount of orange juice Tony drink is (3)/(7) gallon.

change 1 1/2 into a improper fraction. then multiply across. so 2 times 3 over 7 times 2. which equals 6/14. then simplify to get 3/7 as your final answer.
