Answer:
12
Step-by-step explanation:
Answer:
The length of side of original square is: 20 inches
Step-by-step explanation:
Let x be the length of side of original square
Then x+5 will be the side of new square
Th formula for perimeter is:
As we know the perimeter of the new square we can use the perimeter to find the value of x
The value of x is 20 inches.
Hence,
The length of side of original square is: 20 inches
135 times because 675 divided by 5 is 135. you would divide the number of her heart beats by the number
Answer:
254 
Step-by-step explanation:
Surface Area = 2Lh+2Lw+2wh
L=4 cm
h=9 cm
w=7 cm
Surface Area = 2(4)(9)+2(4)(7)+2(7)(9)
Surface Area = (72+ 56 +126)
Surface Area = (72+ 56 +126)
Surface Area =254
As the ratio 0.050:1 for Adalynn and the ratio 0.067:1 for Dwight are not equivalent, it shows that this is not a proportional relationship.
What is a proportional relationship?
Proportional relationships can be described as relationships between two variables that have equivalent ratios.
The ratio of Adalynn that planted 20 peach trees over 400 feet can be expressed as follows:
20:400
Divide through by 400, we have:
0.050:1
The ratio of Dwight that planted 18 plum trees over 270 feet can be expressed as follows:
Divide through by 270, we have:
0.067:1
Since the ratio 0.050:1 for Adalynn and the ratio 0.067:1 for Dwight are not equivalent, this implies that this is not a proportional relationship.
