Answer:
The number of original students desk were there before the purchase is 980 .
Step-by-step explanation:
Given as :
The total number of students and teachers new desks to be purchased = 295
The number of teacher's new desk to be purchased = 50
So , The number of student's new desk to be purchased = 295 - 50 = 245
The number of student's new desk to be replaced this year = 
of the original students desk
Let The number of original students desk were there before the purchase = x
Or, According to question
of x = 245
Or, x = 245 × 4
∴ x = 980
Hence The number of original students desk were there before the purchase is 980 . Answer
Answer:
29.42 units
Step-by-step explanation:
<u>1) Find the perimeter around the semi-circle</u>
To do this, we find the circumference of the circle using the given diameter:
where d is the diameter
Plug in 6 as the diameter
Divide the circumference by 2
Therefore, the perimeter around the semi-circle is 3π units.
<u>2) Find the perimeter around the rest of the shape</u>
Although it's impossible to determine the lengths of the varied sides on the right side of the shape, we know that all of those <em>vertical</em> sides facing the right add up to 6. We also know that all of those <em>horizontal </em>sides facing up add up to 7. Please refer to the attached images.
Therefore, we add the following:
7+6+7
= 20
Therefore, the perimeter around that area of the shape is 20 units.
<u>3) Add the perimeter around the semi-circle and the perimeter around the rest of the shape</u>
Therefore, the perimeter of the shape is approximately 29.42 units.
