Answer:
6 hours.
Step-by-step explanation:
Let t represent the time taken by apprentice in hours to make a set of glasses when working alone.
Part of work completed by apprentice in one hour would be 
.
We have been given that a glassblower can produce a set of simple glasses in about 2 hours. So part of work completed by glassblower in one hour would be 
.
While working together, the job takes about 1.5 hours. So part of work completed by both in one hour would be 
.
Now we will equate sum of work competed by both in hour by work completed by both working together is one hour as:
Therefore, it will take 6 hours for the apprentice to make a set of glasses when working alone.
Answer:
perimeter = 8
Step-by-step explanation:
We require to calculate the area (A) of the circle
A = πr² ← r is the radius
circumference = 4π = 2πr, hence
2πr = 4π ( divide both sides by 2π )
r = 2, hence
A = π × 4 = 4π
The area of the square is therefore 4π and area = s² ← s is the side length
s² = 4π ( take the square root of both sides )
s = 
= 2, hence
perimeter = 4 × 2 = 8

Answer:
the answer is 2100
Step-by-step explanation:
Answer:
d
Step-by-step explanation:
Slope intercept form: y = mx + b
y = -x + 7
x + y = 21
x + y = 21
-x -x
y = -x + 21
y = -x + 7
y = -x + 21
Parallel lines have the same slope. Here, our slope is -1
Therefore, our final answer is d.
Hope this helps!
