Answer:
25
Step-by-step explanation:
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!
Answer:
x = 9
Step-by-step explanation:
Sum of all angles of a triangle = 180
63 + 7x + 6x = 180
63 + 13x =180
13x = 180 - 63
13x = 117
x = 117/13
x = 9
Answer:
126.
Step-by-step explanation:
Each rectangle is a step. We'll start with the top one. This is simple: 6 times 3.

The farthest left is 5 times 3.

The crossed one is 6 times 5.

The one to the right of the crossed one is 3 times 5, again.

The farthest right is 6 times 5, again.

The bottom one is 6 times 3, again.

Now, we add.
