Answer: 3
Step-by-step explanation:
25 x (5 - 2) ➗ 5 - 12
Applying the rule of BODMAS
- Solve task in bracket first
25 x (5 - 2) ➗ 5 - 12
= 25 x (3) ➗ 5 - 12
= 75 ➗ 5 - 12
- Solve task of division next
75 ➗ 5 - 12
= 15 - 12
= 3
Thus, the answer is 3
Answer:
√3
Step-by-step explanation:
The formula for the area of a trapezoid is
Plugging in our information, we have
Combining like terms in parentheses, we have
To cancel the 1/2, we will multiply both sides by 2:
Divide both sides by 8:
Divide both sides by √2:
Since $50 is the fixed rate that would be your y intercept. Since $25 is charged per hour, this value changes and is the slope. Therefore y=25x+50
Answer:
15°, 165°, 195°, 345°
Step-by-step explanation:
The reference angle, 15°, is the smallest angle the terminal ray makes with the x-axis. In the first and fourth quadrants, the positive x-axis is the reference line. The angles will be ±15°, or 360°-15° = 345° if you require all angles to be positive.
In the second and third quadrants, the negative x-axis is the reference. That is 180°, so the reference angle will be added to or subtracted from 180° to give 165° or 195°.
