Of 57 cars making up a freight train, 23 are boxcar. What fraction of the cars are not boxcars?

Answers

The number of non box cars is the number of cars minus the number of boxcars.
This is 57 cars - 23 boxcars = 34 non boxcars

The fraction is the number of nonboxcars divided by the total cars
or
34/57

Answer:

total no of cars =57

Cars which are not boxcars =57-23=34

You just found 13,406,190 pennies! How many dollars did you actually find? If each penny weighs 4 grams, how much did all that loot weigh in lbs?

Answers

Answer: 134,061.9 dollar and 118,222.45 lb

To answer this question you need to convert each unit.
First, 1 dollar equal to 100 pennies. That mean the equation would be: 13,406,190 pennies x 1 dollar/100 pennies = 134,061.9 dollar

Each penny weight 4 grams and 1 lb equal to 453.592grams. Then the equation would be:
13,406,190 pennies x 4 grams/pennies x 1lb/453.592 grams= 118,222.45 lb

Answer:

congrats you just found 118,222.36 pounds of pennies worth $134,061.9

Answers

Answer:

  d  5,15,19​

Step-by-step explanation:

The sum of the shortest two sides must be longer than the longest side. That is only the case for selection D.

__

If the sum is equal to the longest side, the segment ends will meet, but the "triangle" will look like a line segment. Many authors do not allow such a thing to be called a triangle. Hence, 'b' is not an answer to this question.

(Some authors do allow such a triangle, in which case, there would be two answers here: B and D.)

Consider the point. (1, 4, 5) What is the projection of the point on the xy-plane?

Answers

Given :

A point ( 1 ,4 ,5 ).

To Find :

The projection of the point on the xy-plane .

Solution :

Now , to find projection of a point in a plane in a plane we need to replace the coordinate of that remaining axis which is not in the plane .

Here , the plane given is xy-plane . So , remaining axis is z .

So , we replace coordinate of z =0 .

Therefore ,  the projection of the point ( 1 ,4 ,5 ) on the xy-plane is ( 1 ,4 ,0 ) .

Hence , this is the required solution .

3. At the start of summer, Ben has $250 . He takes a summer
job and saves $ 150 per week. Tim has $ 1,650 at the start of
summer , he travels and spends $ 200 per week. At the end of
which week do Ben and Tim have the same amount of money ?

Answers

Answer:

Week 4

Step-by-step explanation:

Ben has $250 in the beginning.  He saves $150 per week.

y = 150x + 250

Tim has $1,650 in the beginning.  He spends $200 per week.

y = 1650 - 200x

We are trying to find which x-value produces the same y-value for both equations.  You can do this by setting both equations equal to each other.

150x + 250 = 1650 - 200x

(150x + 250) + 200x = (1650 - 200x) + 200x

350x + 250 = 1650

(350x + 250) - 250 = (1650) - 250

350x = 1400

(350x)/350 = (1400)/350

x = 4

By week 4, they will have the same amount of money.

The volume of a volleyball is about 288 cubic inches. what is the radius of the volleyball, to the nearest tenth of an inch? use 3.14 for π.
[tex]r = \sqrt{ \frac{3v}{4\pi} } [/tex]

Answers

Answer:

The radius of the volleyball is 8.3 inches

Step-by-step explanation:

Given

[tex]r = \sqrt{\frac{3v}{4\pi}}[/tex]

[tex]v = 288[/tex]

Required

Determine the value of r

To do this, we simply substitute 288 for v and 3.14 for π in the given equation.

This gives

[tex]r = \sqrt{\frac{3v}{4\pi}}[/tex]

[tex]r = \sqrt{\frac{3 * 288}{4 * 3.14}}[/tex]

[tex]r = \sqrt{\frac{864}{12.56}}[/tex]

[tex]r = \sqrt{68.7898089172}[/tex]

[tex]r = 8.29396219651[/tex]

[tex]r = 8.3\ inch[/tex] (Approximated)

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
