Working alone it takes Ryan 13.4 weeks to build a home.Jack can build the same home in 13.1 weeks how long would it take them if
dexar [7]

Answer: 6.62 weeks


Step-by-step explanation:

Time taken by Ryan to build a home = 13.4 weeks

Time taken by Jack to build the same home = 13.1 weeks

Let t be the time to complete a house if they work together, then

\frac{1}{t}=\frac{1}{t}= \frac{1}{\text{time taken by Ryan alone}}+\frac{1}{\text{time taken by Jack alone}}

=\frac{1}{13.4}+\frac{1}{13.1}\\\\=\frac{13.1+13.4}{175.54}\\\\=\frac{26.5}{175.54}

\\\Rightarrow\ t=\frac{175.54}{26.5}\\\Rightarrow\ t=6.62\ weeks

12. Convierte estas fracciones impropias en números mixtos:
Vinvika [58]

        ¡Hola! Voy a hacer el mismo proceso para cada uno.

        Primero, restaré el denominador del numerador hasta que sea una fracción propia. También simplificaré si es necesario.

        Luego, "volveré a sumar los números enteros al número" como un número mixto.

A. 15/7

\displaystyle \frac{15-7-7}{7} =\frac{1}{7}

\displaystyle \frac{1}{7}+1+1=

      \displaystyle 2\frac{1}{7}

B. 16/6

\displaystyle \frac{16-6-6}{6} =\frac{4}{6}=\frac{2}{3}

\displaystyle \frac{2}{3}+1+1=

      \displaystyle 2\frac{2}{3}

C. 12/5

\displaystyle \frac{12-5-5}{5} =\frac{2}{5}

\displaystyle \frac{2}{5}+1+1=

      \displaystyle 2\frac{2}{5}

D. 48/7

\displaystyle \frac{48-7-7-7-7-7-7}{7} =\frac{6}{7}

\displaystyle \frac{6}{7}+1+1+1+1+1+1=

      \displaystyle 6\frac{6}{7}

Quadrilateral A B C D is rotated 145 degrees about point T to form quadrilateral A prime B prime C prime D prime.
Sunny_sXe [5.5K]

The correct answer is option A which is ABCD ≅ A'B'C'D'.

<h3>What is translation?</h3>

The process of changing the location of the image on the coordinate system will be known as the translation.

Quadrilateral ABCD is rotated at 145° about point T. The result is quadrilateral A'B'C'D'.

ABCD ≅ A'B'C'D'is correct Since the quadrilateral remains the same even after rotation of 145 degrees. Its corresponding sides and angles will remain the same.

Thus ABCD is congruent to A'B'C'D'.
