I need help with properties of rhombus, rectangles and squares ​

Mathematics
1 answer:
Flauer [41]3 years ago
6 0

Answer:

  • rhombus
  • x = 70
  • y = 5

Step-by-step explanation:

A quadrilateral with 4 same-length sides is a <em>rhombus</em>.

(If the corner angles are also 90°, then the rhombus is also a square. That is not the case here.)

__

Adjacent angles are supplementary, so ...

  x° = 180° -110° = 70°

Sides are the same length, so ...

  2y = y+5

  y = 5 . . . . . subtract y

_____

If part of the picture was cut off, the right side of the figure may be something other than 2y. If so, formulate the equation appropriately and solve for y.

Solve the inequality
Marianna [84]

Answer:

The answer to your question is the letter A) x ≥ 0.5

Step-by-step explanation:

Inequality

                           2(4x - 3) ≥ -3(3x) + 5x

Process

1.- Expand

                            8x - 6 ≥  - 9x + 5x

2.- Simplify

                            8x - 6 ≥ - 4x

3.- Add 6 units in both sides

                           8x - 6 + 6 ≥ -4x + 6

4.- Simplify

                                8x ≥ -4x + 6

5.- Add 4x in both sides

                                8x + 4x ≥ -4x + 6 + 4x

6.- Simplify

                                12x ≥ 6

7.- Divide by 12 both sides

                                12x/12 ≥ 6/12

8.- Simplify

                                    x ≥ 1/2  or 0.5

The cost of renting ice skates is $4 plus $3.50 for each hour that the ice skates are
Elis [28]

Answer: D)3.5h+4

Step-by-step explanation:

Let h denotes the number of hours that the ice skates are  rented.

Since, The cost of renting ice skates is $4 plus $3.50 for each hour that the ice skates are  rented.

So , the total cost for ice-skating = $4 + $3.50 x (number of hours that the ice skates are  rented.)

= 4+3.50 x ( h) [as expression]

Hence, the expression can be used to find the cost in dollars of renting ice skates for h hours :-

3.5h+4
