mixer [17]

Answer:

$5.83 in taxes.

Step-by-step explanation:

Discounted price of pants: 23.50 × (1 - 0.3) = 16.45

PLEASE ANSWER THIS FAST Will the red square and the orange square always equal the blue square? What colored square is the hypot
Vikentia [17]

Step-by-step explanation:

  • The area of the blue square will always equal the sum of the area of the orange and red rectangles

The pythagorian theorem:

a²+b² = c²

now let a be the side of the red triangle and b the side of the orange one

so a² is the area of the red triangle and b² is the area of the orange one

Let c be the side of the blue rectangle

so c² is the area of it

then what we concluded is right

  • the hypotenuse is the blue side since it is the larger one

-13 times the difference between a number and 60 is equal to the number plus -59
kipiarov [429]
Let n represent the number.
  -13×(n -60) = n +(-59)
  -13n +780 = n -59
  839 = 14n
  839/14 = n = 59 13/14

The number is 59 13/14.

_____
Check
  The difference between the number and 60 is
    59 13/14 -60 = -1/14
  -13 times that value is
    -13*(-1/14) = 13/14
  Compare that to the number plus -59
    59 13/14 -59 = 13/14 . . . . . the same value, as required.

If AABC ~ AAVW, find the values of x and y.
sergey [27]

Answer:

<em>x</em>=28, <em>y</em>=12

Step-by-step explanation:

The squiggly symbol? This means the shapes/angles are congruent, meaning that if you rotated them around, they would match.

x's match runs along the same line as it's match, and same goes for y's. Imagine rotating around the lower triangle and lining it up with the upper triangle.
