The total length of wall is 160 inches
<em><u>Solution:</u></em>
Given that,

1 feet = 12 inches
Therefore,

There are 20 bricks lined up end to end to make the wall
<em><u>To find: Total length of wall in inches</u></em>

Thus we get,

Thus total length of wall is 160 inches
We know Angle HMK is half the sum of Arc JI and Arc HLK. So, we can set up an equation.
8x - 1 = 1/2 (3x + 2 + 15x - 36)
8x - 1 = 1/2 (18x - 34)
16x - 2 = 18x - 34
32 = 2x
16 = x
Then, we can substitute x into Arc HLK
HLK = 15x - 36
HLK = 240 - 36
Arc HLK = 204°
5 baskets...each holds 15 apples....(5 x 15) = 75 apples
4 friends pick the same amount...
4 x 75 = 300 apples picked in total. <==
Answer:
531.167 ft²
Step-by-step explanation:
Given data
Dimension of pool
Diameter =24ft
Radius =12ft
If the cover must hang by 1ft around, then the diameter is 26ft
Radius =13ft
Area of cover = πr²
Substitute
Area = 3.142*13²
Area =3.143*169
Area =531.167 ft²
Hence the minimum area is 531.167 ft²
