Answer:
The possible values for 1/y of the expression 0.125 < y < 0.25 are in the range
4 < 1/y < 8
Step-by-step explanation:
The given information are;
The range of values of y are 0.125 < y < 0.25, therefore, we have;
The boundaries of the function, y are 0.125 and 0.25
The inverse of the boundaries of the function, y are 1/0.125 = 8 and 1/0.24 = 4
Therefore;
The limits of the inverse of the function y are ;
The inequality that represents 1/y is therefore;
1/0.25 < 1/y < 1/0.125 or 4 < 1/y < 8
The possible values of 1/y for the expression 0.125 < y < 0.25 are therefore;
4 < 1/y < 8.
Answer:
4 and 12
Step-by-step explanation:
a = young
b = old
b = 3a, a+b =2a+8 => a = 4, b = 12
Answer:
6(2a+4)-4(3a-4)= (12a+24) +(-12a+16) = 40
Answer:
53
Step-by-step explanation:
Model house dimensions
5 cm × 4 cm = 20 cm²
1 cm = 1.5 m
multiply cm by 1.5 = meters
5 × 1.5 = 7.5 m
4 × 1.5 = 6 m
Real house dimensions
7.5 m × 6 m = 45 m²
