Answer:
False
Step-by-step explanation:
We find the volumes of the two cubes and compare them.
volume of cube = side^3
The volume of the 10-cm cube is:
V = (10 cm)^3 = 1000 cm^3
The volume of the 5-cm cube is:
V = (5 cm)^3 = 125 cm^3
1000/125 = 8
The volume of the 10-cm cube is 8 times the volume of the 5-cm cube.
The statement is false.
Answer:
The correct answer is - 12.
Step-by-step explanation:
Given:
Total number of people = y = 39x+50
Total amount spent y = 518
Solution:
The equation for the number of people who attended the dinner
y = 39x+50
The cost of dinner is equally divided by number of people =
then, 518 = y
placing value, 518 = 39x+50
x = (518-50)/39
= 468/39
= 12
Then number of people attended the dinner = 12
I believe it is zero, because there is no number less than 1.
