Joseph needs to find the quotient of 3.216 ÷8. In what place is the first digit in the quotient?

1 answer:

6 0

If you do long division you will see that 8 cannot go into 3 it will go into 3.2 so the first digit will be in the tenths place 0.4... no need to finish the division since all the question asks is the place of the first digit

Answer:

2.04 miles per hour

Step-by-step explanation:

Given

Noel

$n_1 =6miles$

$r_1 = 2mph$

Casey

$c_1 = 8miles$

$r_2 =1mph$

Required

The rate at which the distance increases

Their movement forms a right triangle and the distance between them is the hypotenuse.

At $n_1 =6miles$ and $c_1 = 8miles$

The distance between them is:

$d_1 = \sqrt{n_1^2 + c_1^2}$

$d_1 = \sqrt{6^2 + 8^2}$

$d_1 = \sqrt{100}$

$d_1 = 10miles$

After 1 hour, their new position is:

New = Old + Rate * Time

$n_2 = n_1 + r_1 * 1$

$n_2 = 6 + 2 * 1 = 8$

And:

$c_2 = c_1 + r_2 * 1$

$c_2 = 8 + 1 * 1 = 9$

So, the distance between them is now:

$d_2 = \sqrt{n_2^2 + c_2^2}$

$d_2 = \sqrt{8^2 + 9^2}$

$d_2 = \sqrt{145}$

$d_2 = 12.04$

The rate of change is:

$\triangle d = d_2 -d_1$

$\triangle d = 12.04 -10$

$\triangle d = 2.04$

HELP PLS and quick find the volume

Ray Of Light [21]

Answer:

V =96 pi

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

Where r is the radius and h is the height

V = 1/3 pi (6)^2 *8

V = 1/3 pi (36)8

V =96 pi

Divide the long leg by the square root of 3 to find the short leg. Double that figure to find the hypotenuse.
