Question

Please help me with my homework!!!!

Answer 1

Answer:

see below

Step-by-step explanation:

-(5)² = -1 * 5² = -1 * 25 = -25

List ascending order:

  -5.3 x 10² = -5.3 x 100 = -530

  -50

  $\frac{1}{2} = 0.5$

  $\sqrt{25} = 5$

  {-5.3 x 10², -50, $\frac{1}{2}$, $\sqrt{25}$}

Describe $\sqrt{8}$: Real, Irrational

List descending order:

  $\sqrt{72} = 8.485$

  6

  $\pi = 3.14159$

  $-\frac{3}{4} = -0.75$

  {$\sqrt{72}$, 6, $\pi$, $-\frac{3}{4}$ }

George loan:

  Principal * rate * time = Interest

  2000 * .034 * 2 = 136

  Principal + Interest = Payback

  2000 + 136 = $2,136

Toy:

  100% - 15% = 85%

  .85 * 4.99 = $4.24
