First, list all the given information:
*100 miles/week
*25 miles/gallon
*$4/gallon
*weekly expenditure reduced by $5
The easiest approach to use here is the dimensional analysis. Cancel out like units if they appear both in the numerator and denominator side. Solve first the original cost. The solution is as follows:
100 miles/week * 1 gal/25 miles * $4/gal = $16/week
The reduced cost would be:
16 - 5 = (New average miles/week) * 1 gal/25 miles * $4/gal
New average miles/week = 68.75 miles/week
Answer:11.5cm, 23cm, 34.5 cm, 69cm
Step-by-step explanation:
1+2+3+6=12
138/12=11.5
First side=11.5cm
Second side=11.5x2=23cm
Third side=11.5x3=34.5cm
Fourth side=11.5x6=69cm
the answer is 1/8 because since one toss would be 1/2 then 1/2 * 1/2 *1/2= 1/8
1/5÷4
multiply by reciprocal
1/5×1/4
1/20
