Korvikt [17]3 years ago

Answer:

Step-by-step explanation:The correct answer is:

If you must have the same number of boys and girls in each group, you can have 7 groups.

Explanation:

To do this, we find the Greatest Common Factor (GCF) of 14 and 21. For this, we find the prime factorization of each number:

14 = 2(7)

21 = 3(7)

The only common factor between these two numbers is 7. Thus we can have 7 groups.

(In each group, we would have 14/7 = 2 boys and 21/7 = 3 girls.)

An opaque cylindrical tank with an open top has a diameter of 3.25 m and is completely filled with water. When the afternoon Sun
kicyunya [14]

Answer:

10.69

Step-by-step explanation:

We must first know that the angle of refraction is given by the following equation:

n_water * sin (A_water) = n_air * sin (A_air)

where n is the refractive index, for water it is 1.33 and for air it is 1.

The angle (A) in the air is 22.8 °, and that of the water is unknown.

Replacing these values we have to:

1.33 * sin (A_water) = 1 * 0.387

sin (A_water) = 1 * 0.387 / 1.33

A_water = arc sin (0.2907) = 16.9 °

now for the tank depth:

h = D / tan (A_water)

D = 3.25

Replacing

h = 3.25 / tan 16.9 °

h = 10.69

Therefore the depth is 10.69 meters.
