➷ You use a rule called 'Keep Flip Change'

Keep the first fraction the same, flip the second fraction upside down (switch the numerator and denominator) and change the divide sign to multiply.

To divide (3/4) / (7/12) multiply 3/4 by 12/7

(3/4) / (7/12) = 36/28 OR 9/7 (simplified version)

➶ Good Luck (:

➷Hello there I hope you having a good day,➷

i would say you do 3/4 divided by 7/2 and the multiply right so i think you flip it so it would 3/4 x 7/12 then that would be 3 x 7 = 21 and 4 x 12 = 48.

So:

To divide 3/4 ÷ 7/12 multiply = 3/4 x 7/12.

3/4 ÷ 7/12 = 21/48.

hopefully that helps you hard question.

Answer:

Step-by-step explanation:

Since the triangle is a right triangle, we can use SOH CAH TOA to find ?. 10 is OPPOSITE to ? and 21 is HYPOTENUSE to ?, so we can use SIN to find ?.

SIN(?) = 10/21

? = ARCSIN(10/21)

? = 28.437

Determine whether each relation is a function. Give the domain and range for each relation.

brilliants [131]

Answer:

Not a function

Domain: {3,4}

Range: {4,5}

Step-by-step explanation:

A function is a relation where each input has its own output. In other words if the x value has multiple corresponding y values then the relation is not a function

For the relation given {(3, 4), (3, 5), (4, 4), (4, 5)} the x value 3 and 4 have more than one corresponding y value therefore the relation shown is not a function

Now let's find the domain and range.

Domain is the set of x values in a relation.

The x values of the given relation are 3 and 4 so the domain is {3,4}

The range is the set of y values in a relation

The y value of the given relation include 4 and 5

So the range would be {4,5}

Notes:

The values of x and y should be written from least to greatest when writing them out as domain and range.

They should be written inside of brackets

Do not repeat numbers when writing the domain and range

Geometry help please

lina2011 [118]

Hello!

The equation to find the volume of a cone is

$\pi r^{2} \frac{h}{3}$

r is radius
h is height

Put in the values we know

$3.14 * 9^{2} * \frac{4}{3}$

Square the number

$3.14 * 81 * \frac{4}{3}$

multiply 81 by 3.14

$254.34 * \frac{4}{3}$

Multiply

339.12

The answer is 339.1 cubic inches

Hope this helps!
