Answer: I think it's $120
Step-by-step explanation: February has 28 days and the dogs eat a whole bag in a week.
So, there will be 4 weeks in 28 days. Since the the cost of a bag is $30 then I guess you would multiply that by each week
So, 30 x 4 = 120
Answer:
There are an infinite number of values satisfying the requirements; every couple of numbers satisfying the following conditions are valid:
base = 60-w meters
width = w meters
0 < w <= 22
Step-by-step explanation:
Since the playground has a rectangular shape, let us us call b the base of the rectangle and w its width. In order for the rectangle to satisfy the condition of P = 120, we need for the following equation to satisfy:
2b + 2w = 120
Solving for b, we get that b = (120 - 2w)/2 = 60 - w .
Given a particular value (w) for the width, the base has to be: (60-w).
Therefore, the possible lengths of the playground are (60-w, w), where 60-w corresponds to the base of the rectangle and w to its width. And w can take any real value from 0 to 22.
Answer:
B. 20 feet
Step-by-step explanation:
<u>If the triangles are similar that means the ratio of the sides of the triangles are the same.</u>
Sense the left side of bigger triangle is 4 times bigger than the bottom side of the triangle, then the left side of the smaller triangle is 4 times bigger than the bottom side.
5×4=20
Answer:
Step-by-step explanation:
Since both equations have 
, we can subtract the second equation from the first to try and solve for 
:
With this, we can plug the value back into the first equation to solve for 
:
Therefore, the solution is
