Answer:
The width of the door is 4 feet.
Step-by-step explanation:
Given,
For house,
Length = 10 ft
Width = 12 ft
Length of door = 8 ft
Quantity of wood used to cover the front of house = 88 sq. ft
we have to find the width of the door.
Solution,
Since the front of the house is in rectangular shape.
So we use the formula of area of rectangle, i.e. length times width.
Area of the front of the house =
Let the width of the door be 'w'.
So, area =
Now according to question,
Ashley does not want to cover her 8 foot tall front door.
So we can say that;
The quantity of wood used to cover the front of the house is equal to area of the front of the house minus area of the door.
Now we substitute the given values;
combining the like terms, we get;
Now dividing both side by '8' using division property, we get;
Hence The width of the door is 4 feet.
Answer:
<h3>Length of carrier A = 2096 feet</h3><h3> Length of carrier B=2082 feet.</h3>Step-by-step explanation:
Given , two air craft carriers are A and B . The carrier A is longer than the carrier B in length.
Total length of two carriers =4178 feet
Difference of two carriers = 14 feet
Let
Length of carrier A =x feet
And
Legth of carrier B =y feet
According to question
The I equation is
x+y=4178
The II equation is
x-y= 14
Substitution method: In this method step I : we find value of x or y from the equation I
Step II: put the value of x or y in II equation then we get the value of another varaiable x or y
Step : Again put the obatined value of variable x or y from step II in equation I then we get value of other variable x or y .
By using substitution method ,
we find value of x from equation I
x= 4178-y
Now, put the value of x in equation II then we get
4178-y-y=14
4178-2y=14
4178-14=2y
4164=2y
y= 2082
Again , put the value of y in equation I
2082 +x=4178
x= 4178-2082
x=2096
Hence, the length of carrier A = 2096 feet
The length of carrier B= 2082 feet
