A taxi driver can cover a distance of 130.16 miles per gallon per 5 gallons of gas if the same taxi driver travel 60 miles at th

uysha [10]

Answer:

$Gallons = 2.305$

Step-by-step explanation:

Given

Rate = 130.16 miles for 5 gallons

Required

Number of gallons used for a journey of 60 miles

The rate in miles per gallon is calculated as:

$Rate = \frac{Distance}{Gallons}$

When distance = 130.16 and gallons = 5, we have:

$Rate = \frac{130.16}{5}$

$Rate = 26.032$

When distance = 60 miles.

Substitute 60 for distance and 26.032 for rate in $Rate = \frac{Distance}{Gallons}$

$26.032 = \frac{60}{Gallons}$

Cross Multiply

$Gallons * 26.032 = 60$

$Gallons = \frac{60}{26.032}$

$Gallons = 2.305$ --- <em>approximated</em>

den301095 [7]

Answer:

Step-by-step explanation:

Sum of first n terms = 243

$a_{1} = 12 \\\\l = 42\\\\S_{n} = \dfrac{n}{2}(a_{1}+l)\\\\\dfrac{n}{2}(12+42) = 243\\\\\\\dfrac{n}{2}*54=243\\\\\\n*27=243\\\\n=\dfrac{243}{27}\\\\n=9$
