Answer:
D
Step-by-step explanation:
If we use the calculator will find out that x= √151/2 ≈ 6.1441
D. 6 < x < 7
x is less then 7 and greater than 6
Without the calculator you can think that 151 is almost 144 that is 12² so
we can approximate √151 to be a bit more then 12
√151/2 = a bit more then 12 /2 = 6 and a bit more
T is greater then or equal to 30
Answer:
1/4
Step-by-step explanation:

Answer:
600ft²
Step-by-step explanation:
the area of a rectangle is L × W.
to get the actual area of the rectangular family room, we have to convert the measurements to (ft).
if 1 cm = 5ft...........what about.....
6 cm= ??
cross multiply..... 6 × 5 ÷ 1 = 30ft.
4cm = ??
cross multiply..... 4 × 5 ÷ 1 = 20ft.
area = L × W.
30ft × 20ft = 600ft²
