Sebanyak 20 pepejal logam berbentuk kubus, dengan sisi 5 m , telah dileburkan untuk membentuk 400 pepejal sfera yang sama. Hitung isi padu, dalam \( \mathrm{cm}^{3} \), setiap pepejal sfera itu. A total of 20 solid metal cubes, with side 5 m , were melted down to form 400 identical solid spheres. Calculate the volume, in \( \mathrm{cm}^{1} \), of each solid sphere. A \( 3.125 \times 10^{-7} \) B \( 3.125 \times 10^{5} \) C \( 6.25 \times 10^{-6} \) D \( 6.25 \times 10^{6} \)

Si dos cuerdas son iguales en longitud en un círculo, ¿qué relación tienen con sus distancias al centro del círculo?

Aidan and Rick are drawing a map of the space used for a game of laser tag. Three of the four vertices of the space are shown in the coordinate plane. The fourth vertex is 7 units directly east of vertex A.Aidan says that the missing vertex should be at (9,3). Rick says Aidan is incorrect.Use the drop-down menus to show how Rick can explain to Aidan why he is incorrect.Click the arrows to choose an answer from each menu.The fourth vertex is east of (-2,3) , so the  is the same as in point A. To find the remaining coordinate, _.Aidan _ The fourth vertex is located at _

4. L'aire d'un trapéze est de \( 135 \mathrm{~m}^{2} \). On sait également que sa hauteur mesure 9 m et que l'une des bases 13 m Quelle est la mesure de l'autré base?

2 In un triangolo isoscele la somma della base e dell'altezza è 90 cm e la base è i \( \frac{3}{2} \) dell'al- tezza. Il lato obliquo è i \( \frac{5}{6} \) della base. Calcola il perimetro e la misura dell'altezza relativa a ciascun lato obliquo. \( [144 \mathrm{~cm} ; 43,2 \mathrm{~cm}] \)
