A parachutist's speed during a free fall reaches 207 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 20 seconds of free fall? Do not round your answers.

Answers

The speed is 57.5 m/s and the parachutist will fall 1150 m in 20 seconds.

Explanation:
We start out with the ratio 207 km/1 hr.

We know that 1 km = 1000 m; this means 207 km = 207*1000 = 207000 m. This gives us 207000 m/1 hr.

We know that 1 hr = 60 minutes, so we have 207000 m/60 min.

We also know that 1 min = 60 seconds, so 60 min = 60*60 = 3600 sec; this gives us 207000 m/3600 sec.

Dividing this, we get 57.5 m/s.

In 20 seconds, the parachutist will fall 57.5(20) = 1150 m.

Answer:

1150 meters

Step-by-step explanation:

Speed of parachute = 207 kilometers per hour

Speed of parachute in meter /second = (207 x 1000)/ (60 x 60)

= 57.5 meter /second

Parachute fall for 20 seconds with a speed of 57.5 meter /second, Thus the distance covered in 20 seconds

= 57.5 meter /second x 20 seconds

= 1150 meters.

Aiden needs 15 liters of cleaning solution. He can buy a 2-gallon jug ($4.28) a 3 gallon jug ($5.92) a 4 gallon jug ($6.56) a 7 gallon jug ($12.98). Which jug should he purchase to get at least 15 liters of cleaning solution and spend the least amount of money?

Answers

We need 15 liters
2 gallon jug 4.28*2=8.56 1 gallon=3.78, 2 gallons=7.57 liters

3 gallon jug 5.92*3=17.76 3 gallons=11.35 liters

4 gallon jug 6.56*4=26.24 4 gallons=15.14 liters

the best solution is to buy 2 times the 2 gallon jug because he will spent
8.56*2=17.12 for 4 gallons(aprox 15 liters)
instead of the 4 gallon jug which costs 26.24

Roger served 5/8 pound of cracker wich was 2/3 of the entire box what was the weight of the crackers originally in the box

Answers

Answer:
original weight of the box = 15 / 16 pounds

Explanation:
Assume that the original amount in the box is x.
We are given that:
5/8 pounds represent 2/3 of the total amount (x).
This can be translated into the following equation:
(2/3) x = 5 / 8

Now, we will solve for x as follows:
(2/3) x = 5 / 8
Multiply both sides by 24 to get rid of the denominators as follows:
(2/3) x * 24 = (5 / 8) * 24
16 x = 15
Divide both sides by 16 to isolate the x as follows:
x = 15 / 16 pounds

Hope this helps :)

The original weight of the crackers in the box is 15/16 pound.

The question asks us to determine the original weight of a box of crackers, given that 5/8 pound of crackers was served, which was 2/3 of the entire box.

We can set up the proportion by stating that 5/8 pound represents 2/3 of the whole, so let's represent the total weight of the crackers with the variable 'w'. The equation to represent this situation is (5/8) pound = (2/3) * w.

To solve for 'w', we'll multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:

(5/8) * (3/2) = w

Simplifying this equation gives us the total weight:

(5 * 3) / (8 * 2) = w

15 / 16 = w

w = 15/16 pound, which is the original weight of the crackers in the box.

A provider order has been received for a dobutamine (dobutrex®) drip at 7 mcg/kg/min. the patient's weight is 220 lbs. how many milligrams per hour should be given?

Answers

To figure this out you first need to determine how many kg there are in 220 lbs. 1 lb equals 0.454 kg, so 220 lbs= 99.88 kg.

It states that a patient receives 7mcg per kg per minute, so the patient will receive 7 x 99.88=699.16 mcg per minute.

You need to convert this to a number of mcg per hour, so multiply the amount by 60 to get 41949.6 mcg per hour.

Final answer:

The patient's weight is first converted from lbs to kg, resulting in 100 kg. The dosage in micrograms per hour is then found to be 42000 mcg/hour. Lastly, this is converted to milligrams to give a final dosage of 42 mg/hour.

Explanation:

This is a question pertaining to medical dosage calculations. First, we need to convert the patient's weight from pounds to kilograms since our dosage is based on that unit. We know that 1 kg equates to approximately 2.2 lbs. So, the patient's weight in kilograms would be 220 lbs/2.2 = 100 kg.

Now, we can use the patient's weight to find the dosage per minute: 7 mcg/kg/min * 100 kg = 700 mcg/min. But the question asks for the dosage per hour, so we must convert minutes to hours: 700 mcg/min * 60 min/hour = 42000 mcg/hour. Finally, we need convert from mcg to mg as the question asked for the amount in milligrams. Since there are 1000 mcg in 1 mg, the dosage becomes: 42000 mcg/hour / 1000 = 42 mg/hour.

Mr. Nelson is buying property in the shape of a triangle to build a new house. If the property costs $42.50 per square foot, how much will he pay?

Answers

First, you find the area of the figure. Use the formula a=h(b/2)

a=h(b/2)
a=47(98/2)
a=47(49)
a=2303

Now, you multiply that by $42.50 to find out how much he will pay.

2,303x42.50=97,877.50.

He will pay $97,877.50.

To find the area of a triangle, multiply the base by the height and divide by 2.
The figure shows a base of 98 ft and a height of 47 ft.

[tex] A = \dfrac{bh}{2} [/tex]

[tex] A = \dfrac{98~ft \times 47~ft}{2} [/tex]

[tex] A = 2,303 ~ft^2 [/tex]

Now that we know the area, we multiply it by the cost of the land per square foot.

2,303 ft^2 * $42.50/ft^2 = $97,877.50

He must pay $97,877.50

Answers

52 percent of 398 is 206.96 that's the answer

We have 398 students with 52% that love music. To find the percentage for this problem, we can use this equation.
S= total number of students in the survey
M= music lovers
S• (52/100)=M
We have to divide the percentage by 100 because that allows use to calculate under 1, so there isn’t an increase in anyway, it should be less than the initial number. So if we multiply 398 by 52, we would get more than 100 percent, using 1 as 100 for percentages allow for an increase or decrease.
398•.52=206.96
For estimation, we can say there are about 400 students and we have to find 50%. Half of 400 is 200, which is a close estimate. So around 200 students in the school share a love of music.

An airplane takes 5 hours to travel a distance of 3300 miles with the wind. The return trip takes 6 hours against the wind. Find the speed of the plane in still air and the speed of the wind.

Answers

The speed with the wind is (3300 mi)/(5 h) = 660 mi/h.
The speed against the wind is (3300 mi)/(6 h) = 550 mi/h.

The speed of the plane in still air is the average of these speeds, 605 mi/h.
The speed of the wind is the difference between the plane's speed in still air and its speed in moving air, 55 mph.

Final answer:

The speed of the plane in still air is 605 miles per hour and the wind speed is 55 miles per hour. This is found through solving simultaneous equations derived from the given distance, and time taken both with and against the wind.

Explanation:

In this problem, the plane's speed in still air can be denoted as 'p' and the wind speed as 'w'. Given the total distance of the trip as 3300 miles, the total time with the wind as 5 hours, and the total time against the wind as 6 hours, we can create two equations: p + w = 3300/5 = 660 miles/hour (with the wind) and p - w = 3300/6 = 550 miles/hour (against the wind).

These equations can be solved simultaneously to get the values of 'p' and 'w'. By adding the two equations, we get 2p = 660 + 550 = 1210. Dividing by 2 gives p = 605 miles/hour. With the value of 'p' we can find 'w' by substituting p = 605 into either of the original equations (let's use p - w = 550): 605 - w = 550, which leads to w = 55 miles/hour.

So, the speed of the plane in still air is 605 miles per hour and the speed of the wind is 55 miles per hour.
