hank the hiker would like to go on a hike. he only has four hours available today for the hike. the expression
1/2d + 1/2e
is used as a general guide to determine how much time, in hours, a hiker should allow for hiking a trail with a distance of d miles and an elevation gain of e thousand feet. the trail hank would like to hike is 6 miles long and has an elevation gain of 3000 ft. will hank be able to complete this hike in the block of time he has available today?

No.

Step-by-step explanation:

Amount of time that Hank has today for hike = 4 hours

Lengtht of hike trail = 6 miles

Elevation gain of trail = 3000 feet

The expression Hanks use as a general guide is:

Here,

d is the distance in miles, so for given case d = 6

e is the elevation gain in thousands, so for given case e = 3

Using these values, the approximate time Hank would need for the hike comes out to be:

Thus, Hank would need 4.5 hours to complete the hike. Since, he has only 4 hours available today he wont be able to complete the hike.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
