bekas [8.4K]

Answer:

y=2\sqrt{3}\ units

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

<em>In the right triangle ABC</em>

AC=BC -----> by a 45°-90°-45° triangle

so

cos(45\°)=\frac{BC}{AB}

BC=ABcos(45\°)

substitute the values

BC=(2\sqrt{2})(\frac{\sqrt{2}}{2})=2\ units

<em>In the right triangle BCD</em>

tan(60\°)=\frac{BD}{BC}

substitute the values

\sqrt{3} =\frac{y}{2}\\ \\ y=2\sqrt{3}\ units

Help me please 40 points
ohaa [14]

Answer:

from April to May is 17%

from May to June is 29%

Step-by-step explanation:

24.  

April   30 hr * 6.5 = 195

May  35 * 6.50 = 227.50

percent increase = (new-original)/original

                               (227.5 - 195)/195

                            = 32.50/195

                             .166666

to change from decimal to percent , multiply by 100

  = 16.67%

round to the nearest whole percent

=17%


b) May  35 * 6.50 = 227.50

  June  45* 6.50 = 292.50

percent increase = (new-original)/original

                                = (292.50-227.50)/227.50

                               = 65/227.50

                              =.285714

to change from decimal to percent , multiply by 100

28.57 %

round to the nearest whole percent

29%
