Answer:
15.7
Step-by-step explanation:
d = 2r
d = 8 thus r = 4
area (kelly) = 4 x4 x = 16
area (paige) = 3 x 3 x = 9
difference = 16 - 9 = 5 = 15.7
Answer:
x ≤ 12.83
(Any number under or equal to 12.8333...)
Step-by-step explanation:
154 ≥ 12x
12.833.... ≥ x
x ≤ 12.83
Answer:
(a) [3 -12 15 -21]
Step-by-step explanation:
Given;
3.[ 1 -4 5 -7]
The product of the function is calculated as;
3.[ 1 -4 5 -7] = [1 x 3 -4x3 5x3 -7x3]
= [3 -12 15 -21]
Therefore the correct option is "a" [3 -12 15 -21]
The number of pieces of sod will Jim need to cover his backyard with sod is 4 pieces.
<h3>What is termed as the unitary method?</h3>
- The unitary method is a process that determines the value of a single unit from the value of multiple units, as well as the value of multiple units from of the value of a single unit.
For the given question;
The backyard of Jim is in the shape of the rectangle.
The dimension of the yards are in given in mixed fraction, convert that in improper fraction as;
- Length : 15 5/6 yards = 95/6 yards
- Width : 10 2/5 yards = 52/5 yards
The area of the rectangle yard is;
Area = length x width
Area = 95/6 x 52/5
Area = 76 sq. yd.
The dimension of the sod in pieces are -
- Length : 1 1/3 yards
- Width : 1 1/3 yards
Area of each sod is -
Area = length x width
Area = 11/3 x 11/3
Area = 121/6 sq. yd.
Thus, the total umber of the sods required for the yard is;
Number = 76 sq. yd. / 121/6 sq. yd.
Number = 3.76 ≈ 4
Thus, the number of pieces of sod will Jim need to cover his backyard with sod is 4 pieces.
