Answer:
D. 150 pounds
Step-by-step explanation:
For be directly proportional, it has to be that as one value increases the other does it equally, so
If 138 pound box has a volume of 23 gallons for 25 gallons ?. For being directly proportional tha value must be higest
138 → 23 
x → 25
Answer: y+-1m -1
Step-by-step explanation:
Answer:
Step 1) y=16-x2. Swap the sides so that all terms of the variables are on the left side. Step 2) 16-x_{2}=y. Subtract 16 from both sides. Step 3) -x_{2}=y-16 Divide the two sides by -1. Step 4). \frac{-x_{2}}{-1}=\frac{y-16}{-1} Dividing by -1 undoes the multiplication by -1. Step 5). x_{2}=\frac{y-16}{-1} Step 6) dived y-16 by -1 And the final answer = x_{2}=16-y
Step-by-step explanation:
Isabelle has a leash for her dog in the backyard. The leash is attached to a post which allows thedog to travel in a circle around the post. The leash is 3 feet long. How much of the yard can thedog reach while on the leash?
255 different groups of 4 paints can be selected out of the 20 paintings.
<h3>How many groups of four paintings can be chosen?</h3>
If we have a set of N elements, the number of groups of different sets of K elements that we can make out of these N is given by:
C(N, K) = N!/(K!*(N - K)!)
In this case we have a total of 20 paintings, and the curator wants to select 4, then we have:
N = 20
K = 4
The number of different combinations of 4 paintings is given by
C(20, 4) = 20!/(4!*16!) = (20*19*18*17)/(4*3*2*1) = 255
This means that 255 different groups of 4 paints can be selected out of the 20 paintings.
