Answer: To find the surface area of a prism we open the solid like a box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.
Step-by-step explanation:
B = number of boys = 8 G = number of girls The average mass of everyone is: [ (55)B + (52)G ] ⁄ (B + G) = 53.2 (55)B + (52)G = (53.2)B + (53.2)G (1.8)B = (1.2)G (1.5)B = G The ratio of girls to boys is —> 1.5 :1 If there are 8 boys, then there are 12 girls
Answer:
r = 4
Step-by-step explanation:
