Answer:
There are 32 dogs and 72 animals in total.
Step-by-step explanation:
In order to find the amount of dogs, you need to set up an equation to solve for the missing variable. Let 'c' be the amount of cats and 'd' be the amount of dogs. We know that there are 40 cats, so c = 40. We also know that there are 25% more cats than dogs, so we can form an equation to express this difference: 1.25d = c, indicating that the number of cats is equal to the total number of dogs, plus an additional 25%. Since we know c = 40, we can set our second equation equal to 40: 1.25d = 40. Using inverse operations, we divide both sides by 1.25 to get d = 32. So, d + c, or 32 + 40 = 72 total animals.
Answer:
The perimeter of room is 
Step-by-step explanation:
We are given the following in the question:
The length and width of a room are measured with uncertainties.
There is uncertainty of 0.1 m in each measurement.
Length = 
Width = 
Formula:
The perimeter of room is given by:
The uncertainties are also added and multiplied.
Thus,the perimeter of room is
Answer:
2x+3x2
+x3
−5
Step-by-step explanation:
Hope this helps
small number = x and large number = 2x + 9
x + 2x + 9 = 2(2x + 9 - x)
3x + 9 = 2x + 18
x= 9
2(9) + 9 = 27
Small number = 9 and large number = 27
