279 miles / 3 hours = 93 miles / hour (divided each side by 3)

465 miles / 5 hours (multiplied each side by 5)

465 * 0.06 = 27.9 (find 6% of 465)

465 + 27.9 = 492.9 miles (add 6% to 465)

The answer would be d: 492.9 miles.

Answer: If the hurricane traveled 279 miles in 3 hours. then his velocity is 279/3 miles per hour = 93 miles per hour.

if the rate increases by 6%, then the velocity at which is moving increases by 6%, then the velocity is 1.06*93 miles per hour = 98.58 miles per hour.

with this velocity, in the lapse of 5 hours the hurricane will travel 5*98.8 miles = 492.9.

So the correct option is D.

5 2/3 gave to her 4 friends how much did each one receive

Olin [163]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

If it is 5 + 2/3

_________________________________

Step (1)

First we have to find all she has :

$5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{5 \times 3}{3} + \frac{2}{3} = \\ \frac{15}{3} + \frac{2}{3} = \frac{17}{3}$

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

$\frac{17}{3} \div 4 = \frac{17}{3} \times \frac{1}{4} = \frac{17}{12} \\$

So each of her friends receive 17/12 .

If it is 5 × 2/3

_________________________________

Step (1)

Firs we have to find all she has :

$5 \times \frac{2}{3} = \frac{10}{3} \\$

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

$\frac{10}{3} \div 4 = \frac{10}{3} \times \frac{1}{4} = \frac{10}{12} \\$

So each of her friends receive 10/12 .

_________________________________

And we're done.

Thanks for watching buddy good luck.

The formula for the nth term of the arithmetic sequence first term is 9 common difference is -2

Yanka [14]

Answer:

$a_n = 9 - 2(n-1)$

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and is called common difference.

The nth term is given by the following equation:

$a_n = a_1 + (n-1)d$

In which $a_1$ is the first term and d is the common difference.

First term is 9 common difference is -2

This means that $a_1 = 9, d = -2$

So, the nth term is given by:

$a_n = a_1 + (n-1)d$

$a_n = 9 + (n-1)(-2)$

$a_n = 9 - 2(n-1)$
