Answer:

N≤(20/3);    Kindly rate

Step-by-step explanation:

The number N of pounds you can buy if you have $20, given that the cost of Berries is $3 per pound will be less or equal to (20/3)

For this case we have, that the berries cost 3 dollars per pound.

If you have $ 20, we want to find the maximum amount (N) of berries that we can buy.

By multiplying the N pounds of berries by $ 3, the product should not exceed $ 20.

So:

N * 3 \leq20

Thus, the inequality is:

N * 3 \leq20

N \leq \frac {20} {3}

Answer:

N \leq \frac {20} {3}

Flying against the wind, an airplane travels 4560 kilometers in 6 hours. Flying with the wind, the same plane travels 3720 kilom
Flura [38]

Answer:

The speed rate of the plane in still air is 1006.67 km/h

The speed rate of the wind is 246.67 km/h

Step-by-step explanation:

To answer the question, we let the speed of the plane in still air = x  km/h

Let the speed of the wind = y km/h

Therefore,

4560/(x - y) = 6 hours and

3720/(x + y) = 3 hours

4560 = 6·x - 6·y.........(1)

3720 = 3·x + 3·y ........(2)

Multiplying equation (2) by 2 and add to (1) gives

12080 = 12·x

x = 12080/12 = 1006\frac{2}{3} km/h

Substituting the value of x in (1) gives

4560 = 6040 - 6·y

6·y = 1480

y = 1480/6 =  246\frac{2}{3}

The speed rate of the plane in still air = 1006.67 km/h

The speed rate of the wind = 246.67 km/h.

Need help ........................
natima [27]

Answer:

m=0.833333

Step-by-step explanation:

(1/16)−3m+1=64

log((1/16)−3m+1)=log(64)

(Take log of both sides)

(−3m+1)*(log(1/16))=log(64)

−3m+1=log(64)

log(1/16)

−3m+1=−1.5

−3m+1−1=−1.5−1

(Subtract 1 from both sides)

−3m=−2.5

−3m

−3

=

−2.5

−3

(Divide both sides by -3)
