The number of square feet of their backyard will NOT be taken up by the pool should be 100 square feet.
Since 1 centimeter represents 5 feet. 4 cm 6 cm And, the area of the Hamiltons' backyard is 900 square feet.
So here it can be like
4cm (5) = 20ft
6cm (5) = 40ft
Now
20ft : 40ft pool
20(40) = 800 square ft
So,
= 900sq ft - 800sq ft
= 100 square feet

Step-by-step explanation:
Average is take by adding all the terms together and dividing by the number of terms. In this case it terms is people in the room.
22= (25+18+17+13+24+x)/6
Where 22 is the average age. The numerator is all the known ages added together, plus x which is the age of the person who just entered. Divided by 6 because you are finding the average age of 6 people.
22 = (25+18+17+13+24+x)/6 Multiply both sides by 6
132= 97+ x Subtract 97 from both sides.
35 = x
The person who just entered the room is 35 years old.
To solve this, we first find the total age of the original five people, then the total age of all six with the given mean age. By subtracting these, we find that the age of the person who entered is 35 years old.
This problem can be solved using simple arithmetic. First, we calculate the total age of the first 5 people, which is 25 + 18 + 17 + 13 + 24 = 97 years. Then, we need to determine the total age of all 6 people. We're told the mean (average) age of these 6 people is 22. We find the total by multiplying the mean by the number of people, so 22 * 6 = 132 years. Finally, to find the age of the person who entered the room, we subtract the total age of the first 5 people from this new total, i.e. 132 - 97 = 35 years. So, the person who entered the room is 35 years old.

What is the area of the circle using π = 3.14?
113.04 in2
452.16 in2
1,017.36 in2
4,069.44 in2
Answer:
1017.36 in²
Step-by-step explanation:
Information we need to know:
Radius = diameter ÷ 2
Area of circle = πr²
1) Find the radius of the circle
We have to make sure the we are using the radius of the circle instead of the diameter as the formula using the value of r. If we were to use the diameter our answer would be wrong.
2) Find the area
To find area we can distribute the numbers given into the formula...

A. 7/2
B. -7/2
C. 10/7
D. -10/7
Step-by-step explanation:
Letthe two numbers be x and y
By the question
x +y =87.....equation (I)
x -y =65......equation (II)
Now adding both equations we get
2x =152
x =152/2
Therefore x =76
Putting x =76in equation i
76+y =87
y =87-76
Therefore y =11
The two numbers are 76and 11.
Hope it helps :)
Answer:
11, 76
Step-by-step explanation:
Let the two numbers be x and y.
According to the given conditions:
x + y = 87.....(1)
x - y = 65....(2)
Adding equations (1) & (2)
x + y = 87
x - y = 65
__________
2x = 152
x = 152/2
x = 76
Plug x = 76 in equation (1)
76 + y = 87
y = 87 - 76
y = 11
Thus the two numbers are 11 and 76.
