$\frac{2}{3} * \frac{4}{7} * \frac{14}{5} \\ \\ = \frac{2*4*14}{3*7*5} \\ \\ = \frac{112}{105} \\ \\ \boxed{=1 \frac{7}{105} }$

To multiply fractions, the numerator of the product is the product of the numerators, likewise for the denominators. (2/3) x (4/7) x (14/5) = (2 x 4 x14) / (3 x 7 x 5) = (112) / (105) = 1 and 1/15 .

Approximate: log 5 ^4/7

wolverine [178]

Do you mean the following:

log(5^(4/7))=around 0.4

log(5)^(4/7)=around 0.815

log(5^4)/7= same thing as top one

log((5^4)/7)=around 1.95

If we can find 1 contradiction then answer is no
hmm

less than one in a fraction is when in form a/b, b>a

1/1000 times 1 and 1/2 same as 1/1000 times 3/2=3/2000
that is less than 1

Answer:

a. 2116 miles

b. 105.8 gallons

c. $305.76

d. cost per gallon = total cost / number of gallons = total cost/105.8

Step-by-step explanation:

The round-trip distance is the sum of the distances there and back. It is double the one-way distance.

round-trip distance = 2 × one-way distance

round-trip distance = 2 × 1058 miles = 2116 miles

The gas used will be the distance divided by miles per gallon.

gas used = round-trip distance / miles-per-gallon

gas used = (2116 mi)/(20 mi/gal) = 105.8 gal

The cost of gas will be the product of cost per gallon and number of gallons.

cost of gas = cost-per-gallon × gallons

cost of gas = $2.89/gal × 105.8 gal = $305.762 ≈ $305.76

The relation used in the previous step can be used to find the cost per gallon. Divide that equation by gallons to get ...

(cost of gas)/gallons = cost-per-gallon

For the same trip, the number of gallons is 105.8, so the equation becomes ...

cost-per-gallon = (cost of gas)/105.8
