Answer:
Step-by-step explanation:
8t = 10(1/2t) + 27
8(2t = 10(t) + 27
Number 4 is correct
Answer: t + 20 = 60; 40 minutes are spent answering phone calls.
Step-by-step explanation: We know that 20 minutes are spent out of a 60 minute day of volunteer work. So, with the equation, t + 20 = 60, we can solve to find out that 40 minutes are spent answering phone calls.
The correct answer is 60⁰.
Step-by-step explanation:
- An angle whose measure is 60⁰ is rotated more than halfway around a circle.
- Since, we have to find the measure of angle.
- As we already know that the angle of rotation about a circle is 360° therefore we have to find more than halfway of this angle.
- Considering that an angle is rotated more than halfway around a circle be

- Multiplying
with 360⁰ - Therefore, it can show as
×360⁰ - Which gives the result to be 60⁰
- Hence, when an angle is measured 60⁰, it is rotating more than halfway around a circle.
- A single rotation around a circle is equal to 360 degrees.
- The measurement of an angle shows the magnitude and direction of the rotation of the angle from its initial position to the final position.
- If the rotation is in a counterclockwise direction, it has an angle with positive measure. If the rotation is clockwise, it has an angle which gives negative measure.
X=x since there is no equation and it cancels out.
