Answer:
100= 10+ 16t
Step-by-step explanation:
If beginning at 10 percent you initially are only in need for 90% charge. Earning 16% every thirty minutes you can initially do x4 for two hours on the charger and know you aren't at 100 yet. (16x4)+10= 64+10= 74. 100-74= 26. You need one more hour (total of 6 half hours) on the charger.
Another way of doing it could be 16÷90 and getting 5.blahblahblah and rounding up.
We can use the first and the last point of the table to find the average rate of change during the 40-minute talk time.
At t=0, the charges are $ 9.95
at t=40, the charges are $12.75
Average rate of change from t=0 to t=40 can be calculated as:
This means, the average rate of change is $0.07, meaning that for each minute of talk time, the monthly bill increases by $0.07. (Option B)
we know that
<u>in the triangle PQR</u>
m∠PQR+m∠QPR+m∠QRP=180°------> the sum of the internal angles of a triangle is equal to 180 degrees
(m∠PQR+m∠QRP)+74°=180°-------> (m∠PQR+m∠QRP)=106°
we know that
If QS and SR are angle bisectors
then
<u>In the triangle QSR</u>
m∠SQR+m∠QSR+m∠QRS=180°-------> equation 1
and
(m∠SQR+m∠QRS)=106°/2--------> (m∠SQR+m∠QRS)=53°
substitute the value of (m∠SQR+m∠QRS)=53° in the equation 1
53°+m∠QSR=180°
m∠QSR=180°-53°-------->m∠QSR= 27°
therefore
<u>the answer is</u>
The measure of angle QSR is 27 degrees
You should specify whether it's 10 degrees east or west, but since 60N 10W is in the ocean, it must be 60N 10E, which is near Oslo, Norway. You can easily input longitudes and latitudes into Google Maps if you ever need help with that.
