Answer: 40°
<u>Step-by-step explanation:</u>
There are 4 pink angles (labeled as "a") and each are the same measure.
There are 4 green angles (labeled as "b") and each measure 50°.
A circle is 360°
4a + 4b = 360
4a + 4(50) = 360
4a + 200 = 360
4a = 160
a = 40
Answer:
42
Step-by-step explanation:
because 15 by 42 = 630
Given parameters:
Number of pencils = pencils
Time taken = minutes
Unknown:
Number of pencils produced in 1 minute;
Solution:
To solve this problem, let us first find the rate of the machine;
Rate of machine =
Rate of machine = = = pencils/minute
Now, number of pencils produces in 1 minute;
Number of pencils = rate of machine x time taken
Number of pencils = pencils/ min x 1 min
Number of pencils = pencils
The number of pencils produced in 1 minute is
