The number is divisible by 6 if divisible by 2 and 3

The number is divisible by 2: if last digit is 0, 2, 4, 6 or 8
The number is divisible by 3: if sum of the digits is divisible by 3

79,002
last digit is 2 - correct
7+9+0+0+2=18 is divisible by 3 (18=3 × 6)

Answer: <u>79,002 is divisible by 6</u>

In circle R with QRS=90 and QR= 3 units find the length of arc QS round to the nearest hundredth

luda_lava [24]

Hello, I Am BrotherEye

Answer:

27.92 units

Step-by-step explanation:

Radius (qr) = r = 16 units

<QŘS = θ = 82°

Length of an arc = (Θ / 360) * 2πr

L = (θ / 360) *2πr

L = (82 / 360) * 2π * 16

L = 0.2777 * 100.53

L = 27.917 units

L = 27.92 unit

Best Of Luck

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.

r-ruslan [8.4K]

Given:

The given quadratic equation is:

$12a^2+9a+7=0$

To find:

The solution for the given quadratic equation in simplest form by using the quadratic formula.

Solution:

Consider a quadratic equation is defined as $ax^2+bx+c=0$ , then the quadratic formula is:

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

The given quadratic equation is:

$12a^2+9a+7=0$

We have, $a=12,b=9,c=7$ . Using the quadratic formula, we get

$x=\dfrac{-(9)\pm \sqrt{(9)^2-4(12)(7)}}{2(12)}$

$x=\dfrac{-9\pm \sqrt{81-336}}{24}$

$x=\dfrac{-9\pm \sqrt{-255}}{24}$

$x=\dfrac{-9\pm i\sqrt{255}}{24}$ $[\because \sqrt{-a}=i\sqrt{a}]$

The solutions of the given equations are $x=\dfrac{-9-i\sqrt{255}}{24}$ and $x=\dfrac{-9+i\sqrt{255}}{24}$ .

Hence, the correct option is B.

Answer:

C. 28.26cm^3

Step-by-step explanation:

In tne formula V= (1/3) pi*r^2*h,

r represents the <u>radius</u> of the base and h represents thr <u>height</u> of the cone.

In this diagram, R is the radius of the base and H is the height of the cone.

Therefore, simply substitute the value of R into r and the value of H into h using the given formula and round your answer to two decimal places.
