Answer:
$937.50
Step-by-step explanation:
25 decrease 25% =
25 × (1 - 25%) = 25 × (1 - 0.25) = 18.75
18.75 × 50 = 937.50
33^2 + x^2 = 65^2
1089 + x^2 = 4225
1089-1089 + x^2= 4225-1089 (subtract both sides)
x^2 = 3136
x = 56cm
Answer:
Arts=295, Commerce=177
Step-by-step explanation:
That the three subjects have a common ratio implies that there is some common factor between them that relates to the actual number of students in each area, so 5:4:3 means 5x:4x:3x for some value of x
We know that there are 236 science students, so 4x = 236 or x = 59
so the number of arts students is 5(59) and the number of commerce students is 3(59)
Arts = 5*59 = 295
Commerce = 3*59=177
