Answer:
Jo's Number is 20.
Step-by-step explanation:
4 - ( 9 x ? ) = 176.
9 x 20 = 180.
9 x 20 = 180, then subtract 180 by 4.
180 - 4 = 176.
Therefore, Jo's number is 20.
Answer:
3.125 g/cm³.
Step-by-step explanation:
The formula for density/mass/volume is d = m/v, where d is density in grams per cm cubed, m is in grams, and v is in cm cubed.
In this case, m = 25 and v = 8.0.
d = 25 / 8.0
d = 25 / 8
d = 3.125.
So, the density of the object is 3.125 g/cm cubed.
Hope this helps!
