Queremos encontrar la medida de un lado de un rectangulo, dado que conocemos la longitud del otro lado y el area del rectangulo.
Veremos que el otro lado del rectangulo mide 3/5 cm
Sabemos que para un rectangulo de largo L y ancho W, el area esta dada por:
A = L*W
En este caso sabemos que el area es igual a (15/40) cm^2.
Y sabemos que uno de sus lados (digamos que es el ancho) mide (5/8) cm.
Entonces podemos reemplazar eso en la ecuación del area:
(15/40) cm^2 = L*(5/8) cm.
Ahora podemos resolver esto para L.
L = (15/40 cm^2)/(5/8 cm) = (15/40 cm^2)*(8/5 cm^-1)
L = 3/5 cm
El otro lado del rectangulo mide 3/5 cm

Answer:
your answer is going to have to be 7
Answer:
14.52% are unicyclists
Step-by-step explanation:
First, we can use proportions to find the number of unicyclists at the convention. Since we know that the ratio of unicyclists to aerial artists is 9:11, and there are 88 aerial artists, we can set up the following equation:
If we cross multiply, we get that 11x = (88)(9). After we divide through by 11 to isolate x, we get that x = (8)(9) = 72
Second, we have to figure out the number of mimes at the convention to figure out the total number of people there. We know that the ratio of unicyclists to mimes is 3:14, and the number of unicyclists is 72. So, we can set up the following proportion:
If we cross multiply, we get that 3y = 1008, or y = 336 mimes
The total number of people at the convention is 336 mimes + 72 unicyclists + 88 unicyclists = 496. Now we have to figure out what percent of 496 is 72 (the number of unicyclists). If we let z = the percentage, we can simply set up an equation that says that 72 is z% of 496:
This means that approximately 14.52% of the performers are unicyclists.

Answer:
(b) 976 m³
Step-by-step explanation:
The total surface area is the sum of the areas of the faces and bases.
The two bases are triangles, each with area ...
A = 1/2bh
So, the two of them together will have an area of ...
A = 2(1/2)bh = bh
where b is the base of the triangle, and h is its height. These values are shown as 14 m and 24 m, respectively.
Total base areas = (14 m)(24 m) = 336 m²
__
The total area of the rectangular faces is the sum of products of length and width. The width of each face is the same as the height of the prism, and the sum of face lengths is the perimeter of the triangular base.
The prism height is 10 m, and the perimeter of the base triangle is (14 m +25 m +25 m) = 64 m. Then the lateral area of the prism is ...
Total lateral area = (10 m)(64 m) = 640 m²
So, the total surface area of the prism is ...
base area + lateral area = 336 m² + 640 m² = 976 m²
