in a village, the cases of a particular infectious disease have been exponentially decreasing at a rate of 95% per year since the people started receiving the vaccine. if there were 200 cases in the village to start with , predict the number of cases after 2 year.

he is going to fill two shelves and the third shelf will only have five video games

fo there supposed to be answer choices there

step-by-step explanation:

answer: number of steps anna and todd walk 150 and 250 respectively.

step-by-step explanation:

since we have given that

for every 3 steps of anna's steps , todd made 5 steps .

so, there will be ratio i.e.

so, the number of steps anna walk = 3x

the number of steps todd walk = 5x

according to question,

so,

number of steps anna walk is given by

number of   steps todd walk is given by

to find perimiter, add all the sides.

60 5/6 + 54 1/3 + 59 1/3 + 56 1/6.

goup like terms:

(60 5/6 + 56 1/6) + ( 54 1/3 + 59 1/3) = 117 + 113 2/3

56 + 60 =   116. 5/6 + 1/6 = 6/6 = 1/ 116 + 1 = 117

54 + 59 = 13. 1/3 + 1/3 =2/3. 13 + /3 = 113 2/3    

117 + 113 2/3 = 230 2/3

answer: 230 2/3
