At a summer camp the campers can choose one of three programmes: camp craft, water sports or hiking. During the first week of camp the campers chose the programmes in the ratio 7:5:8. During the second week of camp the same number of campers chose the programmes in the ratio 7:6:4. Did more campers choose the camp craft programme in the first or second week? How many more?

Second week

Step-by-step explanation:

Given

In first week, campers choose programmes in the ratio of

In second week, this ratio becomes

Suppose 100 campers Joined the camp

Number of hikers who choose camp craft in first week are

Number of hikers who choose camp craft in second week are

Therefore, in second week more campers take part in camp craft.

If 100 campers take part then, 6 more campers takes part in camp craft.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
