An athlete's heart beats an average of 150 times per minute while running. How many times does the athlete's heart beat during a 26-mile race if the athlete runs at a pace of 5 minutes per mile?

Answers

The answer is 19,500 heartbeats.

The number of times the Heartbeat of the athlete if, an athlete's heart beats an average of 150 times per minute is, 19500 times.

What is a division?

It is the basic arithmetic operation, in which you are separating the number into some parts.

Given:

An athlete's heart beats an average of 150 times per minute,

Total distance run = 26 miles,

Total speed = 5 minutes per mile,

Calculate the time of the total run of the athlete,

Time = 26 × 5

Time = 130 minutes

Calculate the number of times the heartbeats of the athlete,

Number of times Heart beat = 130 × 150

The number of times Heart beat = 19500 times.

What is 7.5 × 10^18 and 7 × 10^27 plz help ty

Answers

7.5 x 10^18: Since the exponent of the scientific notation is positive, move the decimal point 18 places to the right.

AN: 7500000000000000000

7 x 10^27: Since the exponent of the scientific notation is positive, move the decimal point 27 places to the right.

AN: 7000000000000000000000000000

Answer:

7,500,000,000,000,000,000 and 7,000,000,000,000,000,000,000,000,000

Step-by-step explanation:

I would assume that's in scientific notation, so to solve you need to get it out of scientific notation.

Since the exponent is positive, move it that many places to the right.

For the first one, it would be 7,500,000,000,000,000,000.

For the second one, it would be 7,000,000,000,000,000,000,000,000,000.

If the exponent was negative, you would've moved the decimal to the left instead.

Hope this helped. It's the only way I could think of to solve it.

The expression 87000(1.12)^t represents the population of a town t hears after 1996. By what percent does the population increase each year? Pls help i need it

Answers

Answer:

12%

Step-by-step explanation:

Percentage increase of something is often represented in a formula of a format like this:

X=Ar^t

Where X represents the total amount after t years.

A or 87000 in this case represents the starting value, which is this case is the starting population of the town. r or 1.12 represents the percentage increase, if it increases by 12% than the next year has 1.12 times as many people as the previous year so this is represented by 1.12 rather than say 0.12 which would indicate a 88% decrease instead. t is the time, no. of years in this case, that has elapsed since 1996.

This formula basically means that a town population of 87000 increases by 12% for every year of time that elapses.

Hope this helped!

.How much force is needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s²?

Answers

2,000 kg at a rate of 3 miles per second to the second square

The force needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s² is 6000 Newtons.

What is force?

Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.

Given:

The mass of the truck = 2000 kg,

The acceleration of the truck = 3 m/s²,

Calculate the force as shown below,

Force needed for truck = Acceleration of truck × mass of the truck,

Force = 2000 × 3

Force = 6000 N

At the beginning of the season, Jamie pays full price for a ticket to see Panters, her favorite baseball team. The Panthers currently have 33 wins and 31 losses. A. Represent the total change in the cost of a ticket given in their losses. B. What is the cost of a ticket for the next game they play?

Answers

Answer:

The answer is B i think

Step-by-step explanation:

Answer:

a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:

Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71

b) The cost of a ticket for the next game given they have 31 losses is:

Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93

Answers

Plug in the x and y values
4(1/2)^2 -3(-5)
Apply the exponent so (1/2)^2 or 1/2 • 1/2 which is equal to 1/4

Now you have 4(1/4) -3(-5)
Multiply them out:
4(1/4)=1
-3(-5)=15 [remember a negative times a negative equals a positive]

Read these two historical documents about the Soviet Unions launch of a space satellitebefore the United States was able to accomplish that goal. Then analyze the launch of Sputnik I as a historical event. Your answer should include: (1) an analysis of each of the documents (2) an analysis of the event as a cause or effect (3) your predictions about future events like the one described in the two documents. Document 1, from NASAs History Web site History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I. The world's first artificial satellite was about the size of a beach ball, weighed only 183.9 pounds, and took about 98 minutes to orbit the Earth on its elliptical path. That launch ushered in new political, military, technological, and scientific developments. While the Sputnik launch was a single event, it marked the start of the space age and the U.S.-U.S.S.R space race. The story begins in 1952, when the International Council of Scientific Unions decided to establish July 1, 1957, to December 31, 1958, as the International Geophysical Year (IGY) because the scientists knew that the cycles of solar activity would be at a high point then. In October 1954, the council adopted a resolution calling for artificial satellites to be launched during the IGY to map the Earth's surface. In July 1955, the White House announced plans to launch an Earth-orbiting satellite for the IGY and asked for proposals from various research agencies to undertake development. In September 1955, the Naval Research Laboratory's Vanguard proposal was chosen to represent the U.S. during the IGY. The Sputnik launch changed everything. As a technical achievement, Sputnik caught the world's attention and the American public off-guard. Its size was more impressive than Vanguard's intended 3.5-pound payload. In addition, the public feared that the Soviets' ability to launch satellites also translated into the capability to launch missiles that could carry nuclear weapons from Europe to the U.S. Then the Soviets struck again; on November 3, Sputnik II was launched, carrying a much heavier payload, including a dog named Laika. Document 2, from the National Park Services web site The National Aeronautics and Space Administration (NASA) was established on October 1, 1958, a year after the USSR sent Sputnik, the first earth satellite, into space. In 1961, after Soviet cosmonaut Yuri Gagarin became the first man in space, the new agency was assigned responsibility for meeting President Kennedy's commitment to put a man on the Moon by the end of the 1960s. Accomplishing the goal under this strict time constraint was an enormous challenge. By 1966, the 10,000 people employed at the space agency in 1960 had grown to 36,000. NASA's annual budget increased from $500 million in 1960 to a high point of $5.2 billion in 1965, 5.3 percent of the federal budget for that year. Approximately 50 percent of that amount went directly for human spaceflight; the vast majority of that went directly toward Apollo. The project eventually cost $24 billion. According to John Noble Wilford, space correspondent for the New York Times, Apollo was the "greatest mobilization of men and resources ever undertaken for a peaceful project of science and exploration." five more than twice a number x Question 21 ptsWhich value below correctly expresses the answer to this calculation:(Reminder: consider sig figs)310 x 0.00189 x 42.0 = what is the coast guards initial opinion of the geatland sailors do parasites have cell walls which era saw the rise of the newspaper columnist The image shows the pH value of some common substances.
