jeka94

Answer: There are 5 guards on each team.

Step-by-step explanation:

Since we have given that

Number of forwards in basketball league = 32

Number of guards in basketball league = 80

We need to find the greatest number of teams possible.

We will find "H.C.F. of 32 and 80.

Since H.C.F. of 32 and 80 = 16

Number of guard would be

$\dfrac{80}{16}=5$

Hence, there are 5 guards on each team.

Math/Physics Problem <br> (I'd be glad if you solved one of them).

Whitepunk [10]

Answer:

19.2

76.8

Step-by-step explanation:

density × volume = mass

mass = 62.4 × (pi × (40/2)² × h)

mass = 78,374.4h

WD = m×9.8×h = 9.8mh

WD = 768,069.12h²

At h = 5

WD = 768,069.12×5²

= 19,201,728 ft-lb

= 19.2 million ft-lb

At h = 10

WD = 76,806,9.12 × 10²

WD = 76,806,912 ft-lb

= 76.8 million ft-lb

<u>Given</u>:

Four lines are marked proportion, the length of TW can be determined by

$TW=a+4+b$

<u>Value of a:</u>

Let us set the proportion for the given lines.

Thus, we have;

$\frac{a}{7}=\frac{4}{5}$

$5a=28$

$a=5.6$

Thus, the value of a is 5.6

<u>Value of b:</u>

Let us set the proportion for the given lines.

Thus, we have;

$\frac{4}{5}=\frac{b}{5}$

$20=5b$

$4=b$

Thus, the value of b is 5.

<u>Length of TW:</u>

The length of TW is given by

$TW=5.6+4+4$

$TW=13.6$

Thus, the length of TW is 13.6
