Answer:
Step-by-step explanation:
S = 2WL + 2LH + 2WH
S - 2WH = 2WL + 2LH
S - 2WH = L(2W + 2H)
(S - 2WH) / (2W + 2H) = L <===
Answer:
The no. of students that play at least one instrument = 448
Step-by-step explanation:
Total number of students surveyed = 480
Students play piano = 253
Students play harp = 268
Students play both harp & Piano = 73
Thus number of student surveyed that they play at least one of the instrument = (Students play piano) + (Students play harp) - (Students play both devices)
= 253 + 268 - 73
= 448
15 bc if u subtract 9 from 24 u get 15
Answer:
as ratio of two type of fabric is different .
hence, the relationship between the number of square yards and the cost
is not proportional between the two types of fabric
Step-by-step explanation:
For a relation to be proportional
a:b = c:d
in other form
a/b = c/d
______________________________________________
Ratio for first type of fabric
cost of fabric/ area of fabric = 31.25/5 = 6.25
Ratio for other type of fabric
cost of fabric/ area of fabric = 71.50/11 = 6.5
as ratio of two type of fabric is different .
hence, the relationship between the number of square yards and the cost
is not proportional between the two types of fabric
