Answer:

It will take 25.2 minutes for Lin to run 21 laps.

Explanation:

This question can be solved by a rule of three.

If takes Lin 6 minutes to run 5 laps. So how many minutes it is going to take for her to run 21 laps?

5 laps - 6 minutes

21 laps - x minutes

5x = 21*6

x = 21*1.2

x = 25.2

It will take 25.2 minutes for Lin to run 21 laps.

What development has led many world leaders to fear that a nuclear arms race had started
Galina-37 [17]

Answer:

The US government's decision to develop a hydrogen bomb, first tested in 1952, committed the United States to an ever-escalating arms race with the Soviet Union. The arms race led many Americans to fear that nuclear war could happen at any time, and the US government urged citizens to prepare to survive an atomic bomb. Their reason for this panicked prognosis was the United States' decision to develop and test a hydrogen bomb, or H-bomb, a nuclear weapon one thousand times more powerful than the atomic bomb that had leveled Hiroshima at the end of World War II.

Wat does it mean if the numbers 789 r glowing on a ouija board
Anestetic [448]
<span>According to the rules of the Ouija board, this means that there is an angel trapped in the board, and that you should say goodbye immediately. In this case, force the planchette (the triangular thing you have your hands on during the game) to glide over the word "goodbye." This way, you can be sure to close the portal of communication to the other realm, and ensure your safety.</span>

Cracking down on dissent during World War I was part of what larger governmental goal in the United States?seizing absolute powe
madam [21]

The larger goal was uniting Americans around the war effort.

Cracking down on dissent would be a negative action in support of the larger, positive goal the government sought. The government wanted a fully united public in support of the war, and so it put out the message that that freedom of speech might have its limits in times of war.
