When you use PEMDAS you end up with the answer of 12. 12 can’t be divided by 7 so 12^13-12^12 is not divisible by 7
Answer:
Step-by-step explanation:
2 easy ways:
1. Divide 7 by 3 then multiply by 2
7/3= seven thirds or 2.333
Now multiply by two to get 14 thirds
or 4.666
2. Multiply 7 by 2/3, or 0.666
This way is a lot easier with a
calculator
The weight of the box is 14/3’s or 4.666
Given:
Length of the playground: 125 ft
Width of the playground: 60 ft
Depth of the mulch: 6 inches
Convert ft and inches to yards
1 yard = 3 feet
Length: 125ft/3ft = 41.67 yd
Width: 60ft/3ft = 20 yd
1 ft = 12 inches
Depth: 6 inches * 1ft/12inches = 6ft/12 = 1/2 ft
Depth: 0.5 ft * 1yd/3ft = 0.5yd/3 = 0.17 yd
Volume = Length * Width * Depth
V = 41.67yd * 20yd * 0.17yd
V = 141.68 yd³
V = 125ft * 60ft * 0.5ft
V = 3,750 ft³
1 cubic yard = 27 cubic feet
3,750ft³ * 1yd³/27ft³ = 3,750 yd³ / 27 = 138.89 or 139 yd³ LETTER B.
- we know x=0 and y=0 and the radius equal 2
so this will be
x^2 +y^2 =2
