Let's find the total cost before the tax and tip.
14+16+2*1.25+2*4.25 = $41
The tip is added before the tax so let's calculate it first.
1.15 * 41 = $47.15
Now add the 7% tax.
1.07 * 47.15 = $50.45
Answer:
a. 30 meters per second
b. -10 meters per second
Step-by-step explanation:
a. Average rate of change for the height from 0 to 6.6 secs can be calculated using the formula,
Thus,
Where,
Plug in the values into the formula:
b. Average rate of change for the height from 8.8 to 13.2 secs = tex] m = \frac{H(b) - H(a)}{b - a} [/tex]
Where,
Plug in the values:
Answer:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
Answer: 35° and 55°
Step-by-step explanation:
For complementary angle, their total value equals to 90°.
Let the measure of the angle be y.
Therefore the complement will be:
= 90° - y
The measure of an angle plus twice its complement is equal to 145 can be expressed as:
y + 2(90 - y) = 145
y + 180 - 2y = 145
y = 180 - 145
y = 35°
The angle is 35° and its complement will be:
= 90 - y
= 90 - 35
= 55°
