Answer: There are 32 dogs and 1 Parrot
Step-by-step explanation: I had a question like this in a math class. What you first do is to recognize that- parrots have 2 legs and dogs have 4. We can do 130/2 = 65 and 130/4= 32.5. Now we know that if there was only one animal, there would be 65 parrots, and 32 dogs- one with half of the legs. Since there is a .5 for the dogs, if we put in one parrot, it would mean that there is exactly 130.
(32 x 4)+(2x1) = 130. There are 32 dogs and 1 Parrot. I hope this answer is ✅ and helps, i just joined the community and this is the first person I answered. Good Luck!!
Answer:
There were 8 total steps
Step-by-step explanation:
Okay, so we start in the middle.
-2 + 4 = 2. We're back in the middle.
2 - 3 = -1. One away from the middle.
-1 + 5 = 4. Now you're at the top.
4 x 2 = 8
Answer:
D) the scaled triangles perimeter is 1/3 the size of the original triangles perimeter
Step-by-step explanation:
Given
Original:
Scaled:
Looking at the dimension of both triangles, The relationship between the original and the scaled copy is:
Hence, the perimeter is:

Given information
-----------------------------------------------------------------------------------------
3 bags + 4 pens = $950
4 bags + 3 pens = $1150
-----------------------------------------------------------------------------------------
Form the 2 equations
-----------------------------------------------------------------------------------------
Let x be the cost of 1 bag.
Let y be the cos of 1 pen.
3x + 4y = 950
4x + 3y = 1150
-----------------------------------------------------------------------------------------
Solve for x and y
-----------------------------------------------------------------------------------------
3x + 4y = 950 -------------- (1)
4x + 3y = 1150 ------------- (2)
----------------------------------------------------------------------------------------
Equation (1) x 4
----------------------------------------------------------------------------------------
12x + 16y = 3800 ------------- (1a)
----------------------------------------------------------------------------------------
Equation (2) x 3
----------------------------------------------------------------------------------------
12x + 9y = 3450 ------------- (2a)
----------------------------------------------------------------------------------------
Equation (1a) - (2a)
----------------------------------------------------------------------------------------
(12x + 16y) - (12x + 9y) = 3800 - 3450
7y = 350
y = 350 ÷ 7
y = 50
----------------------------------------------------------------------------------------
Substitute y = 50 into equation (1)
----------------------------------------------------------------------------------------
3x + 4 (50) = 950
3x + 200 = 950
3x = 950 - 200
3x = 750
x = 250
----------------------------------------------------------------------------------------
Find cost of a bag and a pen
----------------------------------------------------------------------------------------
Bag = x = $250
Pen = y = $50
----------------------------------------------------------------------------------------
Answer: The bag cost $250 and the pen cost $50
----------------------------------------------------------------------------------------
