Some information is missing for #6.
#7: use sine, sin35=h/5.1, h=5.1*sin35, use a calculator, h≈2.9
#23: to find the reference angle, keep subtracting the number by 360, until the remaining difference is the smallest positive number.
1406-360-360-360=326. the reference angle is 326.
now look at the remainder, the terminal line of 326 degree is in the 4th quadrant between 270 and 360, the the reference angle is 360-326=34, the angle between the terminal line and the positive x axis. 34 is the answer.
I do not have answer for this question looking for help.
Answer: 3 times.
Step-by-step explanation:
Here, The Volume of the gas tank = 4710
While, The radius of the cylindrical shaped bucket = 5 in
And, Height of the cylindrical shaped bucket = 20 in
Therefore, The volume of the bucket =
= 3.14 × 5 × 5 × 20 = 1570
According to the question, cylinder shaped bucket is used to fill the tank.
Thus, The number of times the bucket will be used to fill the tank
= The Volume of the gas tank/ The volume of the bucket = 4710/1570 = 3
Therefore, The bucket will be used three times to fill the tank.
