Answer:
80 cubes
Step-by-step explanation:
volume of one small cube = 1 /2 × 1 / 2 × 1 / 2
= 1 / 8cm^3
let x be the number of cubes needed
1 / 8 × x = 10
x = 10 × 8
x = 80 cubes
Answer: 5 weeks
Explanation:
Jess starts with $22 and saves $5 per week, Rosie has $10 and saves $8 per week.
In order to find an equal amount of money between the two girls is by finding a common denominator.
Jess- 22, 27, 32, 37, 42
Rosie- 10, 18, 26, 34, 42
Since we found that they can both end up with $42, after a certain amount of weeks have passed, now you’ll want to count how many numbers are in each row to find the amount of weeks it took to get to an equal amount
Any number that is less than 2 will work. It is impossible to find the square root of a negative number (you can only get imaginary number) since anything square is a positive number.
PS. If you are confused by the answer, just ask me.
Answer:54
Step-by-step explanation:
Pentagon has 5 sides
n=5
Sum of interior angles=180(n-2)
Sum of interior angles=180(5-2)
Sum of interior angles=180x3
Sum of interior angles=540
Size of each interior angle =540/n
Size of each interior angle =540/5
Size of each interior angle=108
x=108/2
x=54
