A trail from City A to City B is 588 miles long. Manfred hikes 2/7 of the trail over a few weeks. How many miles does he hike?

1 answer:

7 0

If Manfred hiked 2/7 of a 588 mile trail, then to find how many miles he has hiked all we need to do is multiply the total miles (588) by what fraction of the miles he has traveled (2/7):
588 * 2/7 = 1176 / 7 = 168

Therefore, Manfred hiked 168 miles.

During a road trip Tony , Tony drove one third the distance that Lana drove. Mark drives 15 more than Lana drove .The total dist

ale4655 [162]

Answer:

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles

Step-by-step explanation:

Given as :

The total distance cover by Lana , Tony , Mark = 484 miles

Let The distance drove by Lana = L miles

The distance drove by Tony = T

The distance cover by Mark = M

So , L + T + M = 484 miles

Now, The distance of Tony = $\frac{1}{3}$ of Lana distance

Or, T = $\frac{1}{3}$ × L

And The distance of Mark = 15 + The distance of Lana

Or, M = 15 + L

Now.

L + $\frac{1}{3}$ × L + 15 + L = 484

Or, 2 L + $\frac{L}{3}$ = 484 - 15

Or, 2 L + $\frac{L}{3}$ = 469

Or, $\frac{7 L}{3}$ = 469

Or, 7 L = 469 × 3

∴ L = $\frac{1407}{7}$

I.e L = 201

The distance drive by Lana = 201 miles

The distance drive by Mark = 15 + L =15 + 201 = 216 miles

The distance drive by Tony = $\frac{1}{3}$ × 201 = 67 miles

Hence The distance drive by each person is

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles Answer

2-4 would equal

-2t/t+3.

Then you have to combine like terms.

A population of beetles are growing according to a linear growth model. The initial population (week 0) is

klemol [59]

9514 1404 393

Answer:

18 weeks

Step-by-step explanation:

We are given the (time, population) pairs (0, 5) and (7, 47). With these values, we can use the two-point form of the equation of a line to write the equation of the linear model.

p = (p2 -p1)/(t2 -t1)(t -t1) +p1

p = (47 -5)/(7 -0)(t -0) +5

p = 6t +5 . . . . . the linear model matching the given points.

For p = 113, the time (number of weeks) is ...

113 = 6t +5

108 = 6t . . . . . . subtract 5

18 = t . . . . . . . . . divide by 6

After 18 weeks, the beetle population will reach 113.
