Answer:
4
Step-by-step explanation:
The area, a of the room is 8* 5.5
a = 44 sqaure feet
one square foot of tiles are sold in packages of 12
To get the number of packages needed, simply divide the area of the room by 12
This gives:
44/12 = 4
= 3.67 round up to the nearest whole number
= 4
I’m not sure if the 15 is the question number but if it is the answer is 32. use PEMDAS

Answer:
N = {13, 15, 17, 19}
Step-by-step explanation:
The natural numbers greater than 11 and less than 21 are:
12, 13, 14, 15, 16, 17, 18, 19 and 20
Odd numbers are numbers that have remainders when divided by 2. Out of the numbers above, the numbers with remainders when divided by 2 are 13, 15, 17 and 19.
Since N is the set of odd natural numbers greater than 11 and less than 21,
N = {13, 15, 17, 19}
Answer:
-39+5(-41)=244
Step-by-step explanation:
Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)
Five times the smallest means 5x
Sum of the largest and five times the smallest means x+2+5x
This sum is -244 means x+2+5x=-244
Solve this equation
x+2+5x=-244
6x+2=-244
6x=-244-2
6x=-246
x=-41
So, smallest number is -41, second is -40 and largest is -39
= -39+5(-41)=244
Hope this helps, have a nice day/night! :D
