MrRa [10]

Answer:

#7

  • C = πd = 3.14*15 in = 47 in (rounded)

#8

  • C₁ = 2πr = 2*3..14*6 ft = 37.68 ft
  • C₂ = πd = 3.14*6 ft = 18.84 ft

<u>The difference:</u>

  • C₁ - C₂ = 37.68 - 18.84 = 19 ft (rounded)

#9

  • No picture attached

#10

  • C = 12 ft
  • d = C/π
  • d = 12/3.14 = 3.82 ft
  • 3 ft < 3.82 ft < 4 ft

Crazy boy [7]

Jason has $2 worth of dimes and quarters. He has 13 more dimes than quarters. The Number of dimes = 15 and Number of quarters = 2.

<h3>What is a linear equation?</h3>

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

The total money = $2 = 200 cents

Types of coins are dimes and quarters

Number of dimes are 13 more than quarters

let number of dimes be x and quarters be y

so our equation

10x + 25y = 200\\x = (y+13)\\10(y+13) +25y= 200\\10y + 130 +25y = 200\\\\35y + 130 = 200\\y = 70/35 = 2
