2 workers, each 8 per hour, for 40hrs a week, so one earns 8 * 40, or 320 bucks, is two workers, so 320 + 320 or 640 bucks
if 2000 is the 100%, how much is 640 in percentage off of it?
well
solve for "x"

well
solve for "x"
Answer:
Step-by-step explanation:
Let be "x" the amount of gasoline in liters that the car's tank had at the beginning of the trip.
1. In the first part of the trip the amount of gasoline the car used can be expressed as:
2. After the first part of the trip, the remaining was:
3. In the second part of the trip the car used of the remaining. This is:
4. The total amount ot gasoline used in this trip was 20 liters.
5. Then, with this information, you can write the following equation:
6. Finally, you must solve for "x" in order to find its value. This is:
Answer:
Minor arc BC - 130° (arc at which inscribed angle is subtended)
The major arc BC - 230°
Step-by-step explanation:
Angle BDC is inscribed angle subtended on the arc BC.
The measure of the angle BDC is 65°.
The Central Angle Theorem states that the central angle from two chosen points B and C on the circle is always twice the inscribed angle from those two points.
By the central angle theorem, the measure of central angle BOC (O is the center of the circle) has the measure of
Hence, the minor arc BC has the same measure as the central angle BOC that is 130°.
The major arc BC has the measure
