Answer:
9 bags
Step-by-step explanation:
Total area = 3.14 × 30²
= 2,826
No. of bags:
2,826/315
= 8.9714285714
To cover the area, he needs 9 bags
We need to find the area of the putting green with a radius of 30 ft
A = pi r^2
A = 3.14 (30)^2
A =2826 ft^2
Each bag will cover 315 ft^2
Divide the area by 315 ft^2 to determine the number of bags
2826/315 =8.971428571 bags
Rounding up to the nearest bag
b. 4.1 shirts
Given data:
number of terms = 12
Terms given are 3, 4, 8, 5, 2, 5, 0, 5, 3, 4, 3, 7
Mean = (sum of terms)/ (number of terms)
Mean = (3 +4+ 8+ 5+2+5+0+ 5+ 3+ 4+3+ 7)/12
Mean = 49/12
Mean = 4.083
Mean = 4.1 (<em>to the nearest tenth)</em>
-10(-2)+y = 4
20 + y = 4
y = -16
----------------
-10(-1)+y = 4
10 + y = 4
y = -6
-10(0) + y = 4
0 + y = 4
y = -4
-10(1)+y = 4
-10 + y = 4
y = 14
-10(2)+y = 4
-20 + y = 4
y = 24
I hope thi helps

slope is -1
we have a point as (-4,3)
we can use slope intercept form of line
we can plug m=-1
now, we can plug point (-4,3)
x=-4 and y=3 and then we can find b
now, we can plug back
and we get
