Answer:
To convert degrees to radians, multiply by π180° π 180 ° , since a full circle is 360° 360 ° or 2π 2 π radians. 225°⋅π180° 225 ° ⋅ π 180 ° radians.

Step-by-step explanation:
A builder was building a fence. In the moring he worked 2/5 of an hour. In the afternoon he wirked for 9/10 of an hour. how many times as long in the morning did he work in the afternoon
Note that:
1 hour = 60 minutes
In the moring he worked 2/5 of an hour.
= 2/5 × 60 minutes
= 24 minutes
In the afternoon he worked for 9/10 of an hour
Hence:
9/10 × 60 minutes
= 54 minutes
How many times as long in the morning did he work in the afternoon?
This is calculated as number of minutes worked in the afternoon ÷ Number of minutes worked in the morning
= 54 minutes/24 minutes
= 2 6/24
= 2 1/4 times
I'm pretty sure it's the commutitative
Answer:
135 to nearest whole number.
Step-by-step explanation:
∑ 5(4/3)^(k-1) from k = 1 to k = 8.
First term = 5 , second term = 5*4/3
This is a Geometric series with first term a1 = 5 and common ratio r = 4/3.
The sum of n terms = a1(r^n - 1) / (r - 1).
The sum of 8 terms is given by 5 * (4/3)^8 - 1) / ( 4/3 - 1)
= 135 to the nearest whole number.
