5 cows and 6 ducks because since they are 11 animals and a total of 32 legs we need to solve for how many per legs which is 5x 4 = 20 legs and 6 x 2 = 12 legs summing them up gives 32 legs in total

Please help me [Below is the graph of equation y=|x+2|-1. Use this graph to find all values of x such that y<0] IF YOU PUT A
Alchen [17]

Answer:

x ∈ (-3, -1)

Step-by-step explanation:

In the graph, the vertical axis represents the y-value, while the horizontal axis represents the x-value.

y < 0 (y smaller than zero) happens in the region where the graph is below the horizontal axis.

Only by looking at the graph, we can see that y < 0 (the graph is below the horizontal axis) for the values of x in the interval (-3, -1)

Then all the values of x such that y < 0 are:

x ∈ (-3, -1)

Find the surface area of the right square pyramid. Round your answer to the nearest hundredth.
jekas [21]

Answer:

A. 176

Step-by-step explanation: First, to find the surface area to each triangle, you multiply the base times the height by 1/2. It is 28 for each triangle. Multiply that by 4, and you get 112. Then, the surface area of the square on bottom is 64. When added together, you get 176. No rounding needed. Hope it helped and is correct!

Can someone help me with this algebra question please 100% correct only

The answer is:  [D]:  " 24 + 2w " .
___________________________________________
Explanation:
___________________________________________
Given: The formula for the Perimeter of a rectangle:
___________________________________________
   P = 2L + 2w ; 
  
                 in which:
                                P = perimeter ;
                                L = length = 12 units (given); 
                                w = width = unknown;
_______________________________________________________
           Find the perimeter, "P", in terms of "w" ; since "w" (width) is unknown; and considering the answer choices given; along with the information provided in the problem, we only have enough information to solve for the perimeter, "P", in terms of "w" ; 
_____________________________________________________
         So, given the formula/equation for the perimeter, "P" :
_____________________________________________________
       P = 2L + 2w ;  we know that:  " L = 12 units " ;
_____________________________________________________
       P = 2*12  +  2w  =  24 + 2w ;  which is:  "Answer choice: [D]" .
