suppose the divisor and the dividend of a division problem are both fractions between 0 and 1, and the divisor is greater than t
Virty [35]

Divisor and Dividend are fractions lying between 0 and 1

Also, Divisor > Dividend

⇒ A smaller number is being divided by a larger number

Whenever a smaller number is divided by a larger number, the quotient is less than 1

E.g. Let divisor be \frac{4}{5} and dividend be \frac{2}{5}

\frac{4}{5} ÷ \frac{4}{5} = \frac{1}{2}, which is less than 1

Hence, the answer is that the quotient will be less than 1

Two metal disks, one with radius r = 2. 50 cm and the other with radius r = 5. 00 cm are welded together and
vova2212 [387]

The total moment of inertia of the two disks will be I = 2.375 × 10-³ Kgm² welded together to form one unit.

<h3>What is moment of inertia?</h3>

Moment of inertia is the quantity expressing a body's tendency to resist angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation.

Using the formulas to calculate the moment of inertia of a solid cylinder:

I = ½MR²

Where;

I = moment (kgm²)

M = mass of object (Kg)

R = radius of object (m)

Total moment of inertia of the two disks is expressed as: I = I(1) + I(2)

That is;

I = ½M1R1 + ½M2R2

According to the provided information;

R1 = 2.50cm = 0.025m

M1 = 0.800kg

R2 = 5.00cm = 0.05m

M2 = 1.70kg

I = (½ × 0.800 × 0.025²) + (½ × 0.05² × 1.70)

I = (½ × 0.0005) + (½ × 0.00425)

I = (0.00025) + (0.002125)

I = 0.002375

I = 2.375 × 10-³ Kgm²

Hence The total moment of inertia of the two disks will be I = 2.375 × 10-³ Kgm² welded together to form one unit.

The circumference of the hub cap of a tire is 83.21 centimeters. Find the area of this hub cap. Use
Elena L [17]

Answer:

<u>551 square centimeters</u>

Step-by-step explanation:

Finding the radius (r) :

  • C = 2πr
  • 83.21 = 2 x 3.14 x r
  • 83.21 = 6.28r
  • r = 83.21/6.28
  • r = 13.25 cm

Finding the area :

  • A = πr²
  • A = 3.14 x (13.25)²
  • A = 3.14 x 175.5625
  • A = <u>551 square centimeters</u> (nearest whole number)

<u></u>

The area of this hub cap is about <u>551 square centimeters</u>.
