Answer:
90 + 10 = 100 ;-;
Step-by-step explanation:
Adult : Children = 5 parts : 2 parts
Total parts = 5+2 = 7 parts
1 part of people in the zoo = 105/7 = 15 people
Number of children in the zoo = 15×2 = 30 chidren
Since the sign is greater than or equal to, it’s a closed circle. I think that means it has a solution. Draw your number line than draw a circle on the 15th line. Make sure the circle is shaded in. Then draw a n arrow a cross the number line, pointing to the right because this equation is say the variable m is greater than or equal to 15

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 .
