Answer:

102

Step-by-step explanation:

triangle area = 180 degrees

straight line = 180 degrees

180 - 127 = 53

49 + 53 + 3rd angle = 180

3rd angle = 78

180-78 = x

x = 102

In 2014 the tenants at Jefferson school’s Fall festival Was 650. In 2015 the attendance was 575. What was the percent change in

The percent change in attendance from 2014 to 2015 is 11.54 %

Solution:

Given that,

In 2014 the tenants at Jefferson school’s Fall festival Was 650

In 2015 the attendance was 575

To find: percent change in attendance from 2014 to 2015

Percentage change equals the change in value divided by the absolute value of the original value, multiplied by 100.

$\text {Percent change }=\frac{\text { change in attendance from } 2014 \text { to } 2015}{\text { atendance in } 2014} \times 100$

Change in attendance from 2014 to 2015 = attendance from 2014 - attendance from 2015

Change in attendance from 2014 to 2015 = 650 - 575 = 75

Therefore percentage change is given as:

$\text {Percent change }=\frac{75}{650} \times 100=\frac{7500}{650}=11.54$

Thus the percent change in attendance from 2014 to 2015 is 11.54 %

What is the radius of a circle with a circumference measuring 24 pie cm?

Tpy6a [65]

By the way, it's pi, not pie. just wanted you to know as you may lose marks in tests for spelling (but i may be wrong)

we know circumference is pi multiplied by the diameter.
the diameter is 2x the radius
we can re-arrange the first fact to get:
diameter (or 2x radius) = circumference divided by pi.
since the circumference is 24pi we can cancel off pi from the circumference (24pi) and pi.
now we have the diameter = 24
since the diameter is 2x the radius you divide both sides by 2 and get:
radius=12cm
