Given : Each Dentalia shell is about 1.5 inches long
⇒ Length of Necklace made with 24 Dentalia shells is (1.5 × 24) = 36 inches
⇒ Length of Necklace made with 18 Dentalia shells is (1.5 × 18) = 27 inches
We can notice that 24 Dentalia shells Necklace is Longer than 18 Dentalia shells Necklace
The Difference of Length of 24 Dentalia shells Necklace and 18 Dentalia shells Necklace gives how much longer the 24 Dentalia shells Necklace is than 18 Dentalia shells Necklace.
⇒ Difference = 36 - 27 = 9 inches
⇒ 24 Dentalia shells Necklace is 9 inches longer than 18 Dentalia shells Necklace
Answer:
Quadrant 1 is positive and positive. If you go down the quadrant below it will be positive, negative.
Answers then would be D and D
Step-by-step explanation:
The linear velocity of the Ferris wheel in inches per second is 18.9 inches/second.
<h3>What is the speed of an object?</h3>
The speed of an object is the ratio of the total distance covered by the object and the total time taken by the object to complete that distance.
Here, the radius of the Ferris wheel is (r) = 30 feet.
The circumference of the wheel is
C= 2πr
C= 2 × π × 30 feet
C= 60π feet
Here, the Ferris wheel completes 7 revolutions.
Therefore, it covers the linear distance of
D= 7 × circumference of the wheel
D= 7 × 60π feet
D= 420π feet
Now, the Ferris wheel took 14 minutes to complete 420π feet.
Therefore, the speed of the wheel is
S= (420π/14) feet/minute
S= 30π feet/minute
S= (30π × 12)/60 inches/second
S= 6π inches/second
S= 18.9 inches/second
Therefore the linear velocity of the object will be 18.9 inches/second

<span>There are 350 students at miller middle school. - it's 25/25
Girls - 12/25 </span><span>of the students
</span>This means that 25/25-12/25=13/25 <span>of the students</span> are boys.
350*13/25=182 students are boys.
