Answer:

The five-year period where the class went from 260 to 400 saw the greatest change in terms of percentage.

Step-by-step explanation:

To calculate the change in percentage we subtract the old number from the new number then divide it by the old number.

400 - 260 = 140

140 ÷ 260 = 0.5385 or 53.85%

525 - 400 = 125

125 ÷ 400 = 0.3125 or 31.25%

Since 53.85% is greater than 31.25%, that means the period where it from 260 to 400 saw the greatest change.

The School principal determined that 1/4 of the original student school desks would need to be replaced this year 50 teachers wo
luda_lava [24]

Answer:

The number of original students desks were there in school before purchase was made is 980 .

Step-by-step explanation:

Given as :

The total number of new desks purchased including teacher and students = 295

The number of new desks purchased for students = \frac{1}{4} of original students desks available

The number of new desks purchased for teachers = 50

Let The number of original students desks available before purchase = S

Now, According to question

∵ The total number of new desks purchased including teacher and students = 295

I.e The number of new desks purchased for students + The number of new desks purchased for teachers = 295

Or,  \frac{1}{4} of S + 50 = 295

Or,  \frac{1}{4} × S = 295 - 50

Or , \frac{1}{4} × S = 245

∴  S = 245 × 4 = 980

So, original desks available for students = S = 980

Hence The number of original students desks were there in school before purchase was made is 980 . Answer

Find the perimeter of this shape
telo118 [61]
To find the circumference of a semi-circle, it would be 1/2<span> π × d. So, pi (3.14) times the diameter, 5 would be 15.7, but then we would need to multiply it by 1/2 to get the circumference for half the circle, and that will get you 7.85. Now you can add all the lengths now. 7.85 + 7 + 5 + 7 = 26.85. Hope this helps! Let me know if you still don't get it. <3</span>
