Answer:
The greatest number of hours for which the car can be rented is<u> 11 hours</u>.
Step-by-step explanation:
Given:
The car rental initial fee = $52.
The rent charge per hour = $8.
Total money available to spend on car rental = $144
Now, to find the greatest number of hours to be spend with $144 on car.
So,<em> we deduct the initial fee first from the available money:</em>
Now, the remaining amount = $92.
Thus, for getting the greatest number of hours we divide the remaining amount by rent charge of car per hour:
According to question the car cannot be rented for part of an hour so the greatest number of hours would be 11 hours.
Therefore, the greatest number of hours for which the car can be rented is 11 hours.
the exact value of sin A to the nearest ten- thousandth is 0. 6625
<h3>Using the pythagorean theorem</h3>
a² + b² = c²
The opposite side is unknown, so use the pythagorean theorem to find it
c = hypotenuse = 4
a= opposite site = ?
b= adjacent side = 3
Substitute into the formula
4² = a² + 3²
16 = a² + 9
a² = 16 -9 = 7
Find the square root
a =√7 = 2. 65
To find Sin A, use
Sin A = opposite side ÷ hypotenuse
Sin A = 2. 65 ÷ 4 = 0. 6625
Thus, the value of sin A is 0. 6625

Answer:
The measure of an interior angle of a regular 15-gon is 120°.
Step-by-step explanation:
We need to determine the measure of the size of an interior angle of a regular 15-gon having 15 sides.
Thus,
The number of sides n = 15
Hence,
Using the formula to determine the measure of an interior angle of a regular 15-gon is given by
(n - 2) × 180° = n × interior angle
substitute n = 15
(15 - 2) × 180 = 15 × interior angle
13 × 180 = 15 × interior angle
Interior angle = (10 × 180) / 15
= 1800 / 15
= 120°
Therefore, the measure of an interior angle of a regular 15-gon is 120°.
So you need to divide your answer by three than multiply by 5 and that would give you your answer
