The design for a mural is 16 in. Wide and 9 in. High. What are the dimensions of the largest possible complete mural that can be
Alexandra [31]

Answer:

Largest possible mural that can be painted on the wall is 24 feet wide and 13.5 feet high.

Step-by-step explanation:

Design of a mural is 16 in. wide and 9 in. high.

Dimensions of the wall are 24 ft by 14 ft.

If we enlarge the size of the design along the width the wall, scale factor to be used,

Scale factor = \frac{\text{Width of the wall}}{\text{Width of the design}}

                    = \frac{24}{16}

                    = \frac{3}{2}

With the same scale factor, height of the design will be,

\frac{3}{2}=\frac{\text{Height of the wall used}}{\text{Height of the design}}

\frac{3}{2}=\frac{\text{Height of the wall used}}{9}

Width of the wall used = \frac{3\times 9}{2}

                                     = 13.5 ft

Therefore, largest possible mural that can be painted on the wall is 24 feet wide and 13.5 feet high.

Please help me with this geo problem
Over [174]

Answer:

  • x = 1.25
  • y = 1.75

Step-by-step explanation:

Find x

  • 8/10 = 5/(5 + x)          Cross multiply
  • 8*(5 + x) = 10*5          Combine on the right
  • 8(5 + x) = 50              Remove the brackets on the left.
  • 40 + 8x = 50              Subtract 40 from both sides.
  • 40-40 +8x = 50-40    Combine
  • 8x = 10                        Divide by 8
  • 8x/8 = 10/8                 Divide
  • x = 1.25

Find y

  • 7/(7 + y) = 8/10                    Cross multiply
  • 8*(7 + y) = 10 * 7                  Combine the right
  • 8(7 + y) = 70                        Remove the brackets.
  • 56 + 8y = 70                       Subtract 56 from both sides
  • 56 - 56 + 8y = 70 - 56       Combine
  • 8y = 14                                Divide by 8
  • y = 1.75

Number sequence? does that mean:

By the way I am a snake because I was born in 2001.
