23
because
the pattern is
(5 10) ..1.. (15 20) ..2.. (25 30) ..3..
..1... = 3
..2.. = 13
so ..3.. = 23
Answer:
41-275=234
15-47=62
-72-{151}=223
612-144=174
Step-by-step explanation:

Step-by-step explanation:
Answer:
The mass of the cubic granite block is 1408 g .
Step-by-step explanation:
Formula
Volume of a cube = a³
Where a is the side of the cube .

As given
one side of the cube is 8 cm .
(The figure is shown below.)
Thus
Put in the formula
Volume of a cubic granite block = 8 × 8 × 8
= 512 cm³
As given
The density of cube is 2.75 g/cm³.
Put in the formula

Mass = 2.75 × 512
Mass = 1408 g
Therefore the mass of the cubic granite block is 1408 g .
Change logb24 into logb(8*3).
Next use the product rule to rewrite logb(8*3) as a sum.
logb8 + logb3
Now substitute the values given.
0.71 + 0.23 =
0.94
