Calculate the estimated density of each ball. use the
formula
d= m/v
where d is the density, m is the mass, and v is the
volume. record your calculations in table a of your
student guide.
given that the density of water is 1.0 g/cm", make a
prediction about whether each ball will float in water.
record your prediction in table a.
what is the estimated density of the table tennis ball?
record your answer to the nearest hundredth.
0.08
g/cm3
what is the estimated density of the golf ball? record
your answer to the nearest hundreth.
g/cm3

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
