Answer:
56 feet.
Step-by-step explanation:
4k+6k+8k=18k=126⟹k=7
Therefore, the lengths are 4⋅7=28, 6⋅7=42 and 8⋅7=56 feet.
Answer:
D, 34,000 milliliters
Step-by-step explanation:
There are 1,000 milliliters in a liter. So, if we had 1 liter, we would have 1*1,000=1,000 milliliters.
When you change the 1 liter to 34, we can just substitute 34 for 1. So, the answer is 34*1,000=34,000 milliliters, or D
1/2, because you multiply your denominators together and your nominnators together, getting you 6/23, then you simplify to get 1/2.
Answer:
240 ft^2
Step-by-step explanation:
If you know you have 6 triangles then you can just find the area of one and then multiply by 6. First find your formula: (b)(h)/ 2
Next plug in: (8)(10)/2 = 40
Now you know the area of one so multiply by 6: (40)(6) = 240 ft^2
We have that
set of data [<span>8, 12, 15, 17, 18]
step 1
Find the mean
</span>[8+ 12 + 15 + 17 + 18]/5-------> 70/5------> 14
step 2
for each number: subtract the Mean and square the result
(8-14)²----->36
(12-14)²----> 4
(15-14)²----> 1
(17-14)²----> 9
(18-14)²----> 16
step 3
<span> work out the mean of those squared differences
[36+4+1+9+16]/5-----> 66/5-----> 13.2----> </span><span>this value is called the "Variance"
step 4
</span><span>Take the square root of that
</span>standard desviation=√13.2-----> 3.63-------> 4
the answer is
4
