Answer:

(A) The length of the diameter of a sphere is two times the length of the radius of the sphere

Step-by-step explanation:

Sphere: A round solid figure, or its surface, with every point on its surface equidistant from its center.

Also, The length of the diameter of a sphere is two times the length of the radius of the sphere that is D=2r where D is the diameter and r is the radius of the sphere.

Therefore, out of all the options given, only Option (A) is the correct option because it properly describes the statement about sphere.

Dafna11 [192]
The future amount of the current deposit given that the interest is simple and yearly is computed through the equation,
                                 F = P x (1 + in)
where P is the principal amount, F is the future amount, i is the interest (in decimal form) and n is the number of years.

In this certain problem, we substitute the known values to the equation and solve for P,
                             2419.60 = P x (1 + (0.052)(1)) 
                                       P = 2300
Thus, the initial investment was worth $2,300.

Can someone explain to me how to turn a fraction into a decimal..? And a decimal into a fraction? Be specific please! I have a t
cricket20 [7]
To turn a decimal into a fraction move the decimal point two spots over (Ex: 0.34=34%). To turn a fraction into a decimal get the denominator to 100 by multiplying both the top and bottom by whatever number needed (must both be multiplied by the same number) or divide to top number into the bottom number of you can’t multiply.

Can someone help.
r-ruslan [8.4K]

Answer:

m∠C = 38°  (nearest whole number).

Step-by-step explanation:

To find the missing angle, use the Sine Rule.

<u>Sine Rule</u> (for angles)

\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}

where:

  • A, B and C are the angles
  • a, b and c are the sides opposite the angles

Given:

  • A = 53°
  • a = 18
  • c = 14

To find m∠C, substitute the given values into the formula and solve for C:

\implies \sf \dfrac{\sin 53^{\circ}}{18}=\dfrac{\sin C}{14}

\implies \sf \sin C= \dfrac{14 \sin 53^{\circ}}{18}

\implies \sf C= \sin^{-1} \left( \dfrac{14 \sin 53^{\circ}}{18}\right)

\implies \sf C= 38.40096301...^{\circ}

Therefore, m∠C = 38°  (nearest whole number).

Lady bird [3.3K]

Answer:

3.6 minutes.

Step-by-step explanation:

According to the data given in the question, between 9 and 10 AM, 220 passengers have checked in which means that the check-in rate is 3.6 passengers per minute. If the average number of passengers waiting for check-in is 32 and if we assume that the check-in rate is constant throughout the day, then the average passenger had to wait in line for 3.6 minutes.
