Answer:

This is an identity or infinite solutions

Step-by-step explanation:

10x - 12y = 22

5x - 6y = 11

-2(5x - 6y = 11 )

-10x + 12y = -22

10x - 12y = 22

0=0

Identity solution

Reggie bought a pair of hiking boots that were discounted by 30% off the original price. If the original price was $66.00, what
Free_Kalibri [48]

Answer:

$46.20

Step-by-step explanation:

We can create a proportion to find the sale on the original price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. If the price is discounted by 30% then we pay 70% of the price.

\frac{70}{100} =\frac{x}{66}

We begin solving by cross multiplying numerator to denominator of each fraction.

70(66)=100(x)\\4620=100x\\\frac{4620}{100}=\frac{100x}{100}  \\46.20=x

Steve needs to ship a box of dice, each of which is a cube with a volume of 1 cubic centimeter. How many dice can Steve fit in t
AfilCa [17]

Answer:

D. 1,944

Step-by-step explanation:

the box's size is missing, so I looked for a similar question:

the box measures:

  • base (12 cm)
  • width (9 cm)  
  • height (18 cm)

total volume of the box = 12 x 9 x 18 = 1,944 cm³

since each dice occupies a volume of 1 cm³, then you can fit 1,944 dices in each box.

Using the identity sin? O + cos? O = 1, find the value of tan O, to the nearest
Novosadov [1.4K]

Answer:

<u>3.7</u>

Step-by-step explanation:

<u>Given</u>

  • sin²θ + cos²θ = 1
  • sinθ = 0.27

<u>Solving for cos</u>θ

  • cos²θ = 1 - sin²θ
  • cos²θ = 1 - (0.27)²
  • cos²θ = 0.0729

<u>Finding tan</u>θ

  • tanθ = sinθ / cosθ
  • tanθ = 0.27 / 0.0729
  • tanθ = <u>3.7</u>

<u>Verifying it lies in the range</u>

  • θ = tan⁻¹ (3.7)
  • θ = 74.88°
  • Range is : 0 < θ < π/2 [or 0 < θ < 90°]
  • It lies in the range [Verified]
