Answer:
hand sanitizer is $2.50 disinfecting wipes $4.00 each
Step-by-step explanation:
Answer: the smaller number is 11, and the larger number is 28
Step-by-step explanation:
Let x = the smaller number; then the greater number is 3x-5. When you add these they must equal 39, so:
x + (3x-5) = 39
4x - 5 = 39; now add 5 to both sides:
4x = 44; now divide both sides by 4, and you get x =11, which is the smaller number. The larger number would be 3(11)-5 = 33 - 5 = 28
What problems are you talking about?
Arrange the numbers in order from smallest to largest:
28, 35, 40, 40, 45, 52, 54, 58, 60
Median is the middle value = 45
Mode is the number that appears most = 40
Mean is the average. Add the numbers and divide:
412/9 = 45.77 = 45.78
Range is difference between highest and lowest = 60 - 28 = 32
Answer:
11.33 in. to the nearest hundredth.
Step-by-step explanation:
The perimeter of the shaded area = length of the 2 straight lines + the length of the 2 arcs = 4 + length of the 2 arcs.
Calculate the length of the outer arc:
This equals (30 / 360) * perimeter of the largest circle
= 1/12 * 2 π * 8
= 4/3 π in.
The inner circle has a radius of 8 - 2 = 6 ins
so the length of the inner arc
= 1/12 * π * 2 * 6
= π in.
So the perimeter of the shaded region = 4 + 4/3 π + π
= 4 + 7π/3
= 11.33 in.
