(1/2) / (3/4) = 1/x....1/2 bedroom to 3/4 hr = 1 bedroom to x hrs
cross multiply
1/2x = 3/4
x = 3/4 * 2
x = 6/4 of an hr
We know that
circumference=pi*D
where D is the diameter
diameter=4 ft
circumference=4*pi ft
if one revolution is -------------> 4*pi ft
1320 rev-------------> x
x=1320*4*pi-----> x=5280*pi ft/hout
convert ft to miles
1 mile-----------> 5280 ft
so
5280*pi ft----------> is pi mile
5280*pi ft/hour------> is equal to pi mile/hour
the answer is the option
<span>a. pi</span>
Parallelogram area formula: bh
6*7=42
The area of the parallelogram is 42square meters
2(p+1)=16
2p+2=16
2p= 16-2
2p= 14
p= 14 ÷2
p= 7
