It rejects 3 out of every 200 pairs of shoes as defective. What percentage of shoes are rejected?(1 point) Responses 6% 6% 15% 15% 3% 3% 1.5% 1.5%
Question 11: To find 37% of a meter, we divide 37 by 100 and then multiply it by a meter:
(37/100) * 1 meter = 0.37 meters
Therefore, the best choice to represent 37% of a meter is 0.37 meters.
Question 12: To find the number of students who are left-handed, we multiply the total number of students by the percentage of left-handed students as a decimal:
840 * 0.05 = 42
Therefore, there are 42 left-handed students in Marieka's summer camp.
Question 13: To find the percentage of shoes that are rejected, we divide the number of rejected shoes by the total number of shoes and then multiply it by 100:
(3/200) * 100 = 1.5%
Therefore, 1.5% of shoes are rejected by the shoe factory.
Question 11:
To find 37% of a meter, we can multiply the meter by 0.37 since 37% is equivalent to 0.37.
Therefore, 37% of a meter is equal to 0.37 meters, which can also be expressed as 37 centimeters.
Answer: 37 cm
Question 12:
To find the number of students who are left-handed, we need to calculate 5% of the total number of students in the summer camp.
5% of 840 students can be found by multiplying 840 by 0.05.
840 * 0.05 = 42
Therefore, there are 42 students in the summer camp who are left-handed.
Answer: 42 students
Question 13:
To find the percentage of shoes rejected, we need to divide the number of rejected shoes by the total number of shoes inspected.
The ratio of rejected shoes to total shoes is 3 out of 200, which can be written as 3/200.
To convert this ratio to a percentage, we can multiply it by 100.
(3/200) * 100 = 1.5
Therefore, 1.5% of shoes are rejected by the factory.
Answer: 1.5%
For question 11:
To find what percentage of a meter is equal to 37%, we can set up the equation:
x = 0.37 * 1 meter
To find x, we multiply 0.37 (which represents 37%) by 1 meter. Therefore, the answer is 0.37 meters.
For question 12:
To find how many students are left-handed, we can use the percentage given and the total number of students:
Number of left-handed students = 5% * 840 students
To find the answer, we multiply 5% (which can be written as 0.05) by 840 students. Therefore, the number of left-handed students is 42.
For question 13:
To find the percentage of shoes that are rejected, we can use the ratio given:
Percentage of rejected shoes = (3 / 200) * 100
To find the answer, we divide the number of rejected shoes (3) by the total number of pairs of shoes (200), and then multiply by 100 to convert it into a percentage. Therefore, the percentage of shoes rejected is 1.5%.
