Step-by-step explanation:
if 4 men did the job in 12 days , then each of the 4 men worked for 12 days , which means they worked for 4*12=48 days , so the job takes 48 work days to complete. If all men work at the same rate, then these other 6 will complete the job in
Therefore, it’ll take the group of 6 men 8 days to complete the job.
<u>Given</u>:
Given that the radius of the circle is 4 units.
The given figure is 
th of the circle.
We need to determine the area of the th of the circle.
<u>Area of the circle:</u>
The area of the circle can be determined using the formula,
Substituting r = 4, we have;
Thus, the area of the circle is 16π units².
<u>Area of the </u><u>th of the circle:</u>
The area of the th of the circle is given by
Therefore, the area of the shape is 12π units².
Answer:
(-4 ,3)
Step-by-step explanation:
Point a lies on -4
Point B lies in between 2 and 4 so lets call it 3

Answer: 31 & 32</h2>
Step-by-step explanation:
So we first need to assign letters to represent the numbers.
Let 'a' be the larger number and 'b' the smaller.
Now we can use this to write equations that we can solve simultaneously to find both 'a' and 'b'.
according to the question:
a + 4b = 156 [1]
a - b = 1 [2] (this is because the integers are consecutive
We can rearrange [2] to make 'a' the subject: a = b + 1 [3]
We can then substitute [3] into [1] and solve for b
(b + 1) + 4b = 156
5b = 155
b = 31
Now we can find 'a' using [3]
a = 31 + 1
a = 32
