A local library manager randomly surveys 80 patrons about the type of book they borrow when they visit the library. The manager finds that 3 patrons borrow novels. If the local library has 345 patrons, approximately how many of them borrow novels when they visit the library? Round your answer to the nearest whole number..
We can use proportion to solve this problem:
3/80 = x/345
Where x is the number of patrons who borrow novels out of the entire population of 345 patrons.
To solve for x, we can cross-multiply:
80x = 3 * 345
x = (3 * 345) / 80
x ≈ 12
Therefore, approximately 12 patrons out of the entire population of 345 patrons borrow novels when they visit the library.
Use the excerpt from the Civil Rights Act of 1964 to answer the question.
Which of the following MOST DIRECTLY helped rally support for this act? EXPLAIN
A. Greensboro sit-in
B. March on Washington
C. Montgomery bus Boycott
D. Brown v. Board of Education
B. March on Washington most directly helped rally support for the Civil Rights Act of 1964. The March on Washington was organized by civil rights leaders, including Martin Luther King Jr., to advocate for civil and economic rights for African Americans. The march drew a crowd of over 250,000 demonstrators, including white Americans and civil rights activists from all over the United States. It was a powerful display of solidarity and raised awareness of the injustices that African Americans faced. The public attention generated by the March on Washington helped build momentum for the Civil Rights Act of 1964 and contributed to its successful passage.
We have the following information:
- The local library manager surveyed 80 patrons and found that 3 patrons borrow novels.
- The local library has a total of 345 patrons.
To find the approximate number of patrons who borrow novels, we can create a proportion using the information from the survey. Let's call the unknown number of patrons who borrow novels "x".
From the survey, we know that:
3 out of 80 patrons borrow novels.
Setting up the proportion:
3/80 = x/345
To solve for "x", we can cross-multiply:
80x = 3 * 345
Now, let's solve for "x":
80x = 1035
x = 1035/80
x ≈ 12.94
Rounding this to the nearest whole number, we find that approximately 13 patrons out of 345 borrow novels when they visit the library.
