Answer: 12.6 m
Step-by-step explanation:
Use the pythagorean theorem, we get that the height, or x, is
sqrt(22x22-18x18) = sqrt(484-324) = sqrt(160) = 4sqrt(10) = 12.6 m
Answer:
The second one
Step-by-step explanation:
The second one
The number of 10 chips stacks that Dave can make if two stacks are not considered distinct is 110.
The solution
To get the symmetric stacks, one has to subtract the symmetric stacks to know the ones that are asymmetric.
The symmetric are flipped. Given that they are double counted what we have to do is to divide through by 2.
6/2 = 3
10/2 = 5
4/2 = 2
1/2(10C6) - (5C3) + (5C3)
0.5(210-10+10)
= 110

To do the comparison, we'll use the following temperatures:
Day 1: 5°F
Day 2 : 1.5°F
Comparison of Day 1 and Day 2:

3.
The temperature that's the closest to 0 during the week is -0.5°F. Using absolute value, we can see that the distance from 0°F to -0.5°F is the smallest of all the temperature measurements.
4.
The temperature that's the farthest to 0 during the week is 5°F. Using absolute value, we can see that the distance from 0°F to 5°F is the biggest of all the temperature measurements.
5.
The coldest temperature is -4°F. This is the value that is farthest to the left of 0°F on the number line.
6.
The warmest temperature is 5°F. This is the value that is farthest to the right of 0°F on the number line.
