Answer:
24 square blocks
Step-by-step explanation:
Average of 2 numbers is 40
so total = 2 x 40 = 80
300 - 80 = 220
average of remaining 10 numbers = 220/10 = 22
answer
B) 22
As they both are tangents of the same circle, their lengths must be equal.
RS = RT
x/4 = x-6.3
x = 4x - 25.2
4x-x = 25.2
3x = 25.2
x = 8.4
As, RS = x/4, it will be equal to 8.4/4 = 2.1
SO, YOUR FINAL ANSWER IS RS = 2.1
Answer:
The fencing will cost $334
Step-by-step explanation:
To know how much the fencing will cost. We need to calculate the total length around the garden.
This is same as the circumference of the circular garden.
Mathematically, the circumference C of a circle can be calculated using the formula
C = 2 × π × r
where r = 15 feet
C = 2 × 22/7 × 15
C = 94.3 feet
Now the fencing cost $3.54 per foot
Total cost = 94.3 × 3.54 = $333.822
or simply $334 to the nearest whole dollars
