Which of the following fractions is equivalent to 5\6​

Answers

5/6=10/12

5/6 is equal to all of these

5/6 = 10/12 = 15/18 = 20/24

= 25/30 = 30/36 = 35/42 = 40/48

= 45/54 = 50/60 = 55/66 = 60/72

= 65/78 = 70/84 = 75/90 = 80/96

= 85/102 = 90/108 = 95/114 = 100/120

= 105/126 = 110/132 = 115/138 = 120/144

= 125/150 = 130/156 = 135/162 = 140/168

= 145/174 = 150/180 = 155/186 = 160/192

= 165/198 = 170/204 = 175/210 = 180/216

= 185/222 = 190/228 = 195/234 = 200/240

= 205/246 = 210/252 = 215/258 = 220/264

= 225/270 = 230/276 = 235/282 = 240/288

= 245/294 = 250/300 = 255/306 = 260/312

= 265/318 = 270/324 = 275/330 = 280/336

= 285/342 = 290/348 = 295/354 = 300/360

= 305/366 = 310/372 = 315/378 = 320/384

= 325/390 = 330/396 = 335/402 = 340/408

= 345/414 = 350/420 = 355/426 = 360/432

= 365/438 = 370/444 = 375/450 = 380/456

A car travels 700m North and then 300m East and then 300m South. This journey takes 1 min and 40s. The total
displacement is m
and the average velocity is
m/s

Answers

Answer:

Displacement is 500m

Step-by-step explanation:

North=700m

East= 300m

South=300m

y=700-300=400m

x= 300m

We know that the displacement is found using the Pythagoras theorem

let the displacement be d

d^2= x^2+y^2

d^2= 400^2+300^2

d^2= 160000+90000

d^2=250000

d=√250000

d=500m

9/2 divided by 2/9 this is dividing fractions

Answers

Answer:

4/81

Step-by-step explanation:

Don't ask i just know

-Too much work to explain

The division of of 9/2 by 2/9 is equal to 81/4.

To divide fractions, multiply the first fraction by the reciprocal of the second fraction.

In this case, we need to divide 9/2 by 2/9.

Dividing fractions: (a/b) ÷ (c/d) = (a/b) * (d/c)

So, we can rewrite the expression as:

(9/2) ÷ (2/9) = (9/2) * (9/2)

Now, let's perform the multiplication:

(9/2) * (9/2) = (9 * 9) / (2 * 2) = 81/4

Therefore, the division gives 81/4.

Given
F(x) = (3x - 12) + 2, what is the domain in set notation?
O {x|x ER, X2 4}
O {x|x ER, XS4}
{x|x ER, X2}
O {x|x ER, XS 2

Answers

The domain in set notation is {x | xER, -∝ < x < ∝}

How to determine the domain

From the question, we have the following parameters that can be used in our computation:

F(x) = (3x - 12) + 2

There is no restriction on the input values, x

So, the domain of F(x) = (3x - 12) + 2 is all real numbers, since there is no restriction on the input (x).

In set notation, we have

{x | xER, -∝ < x < ∝}
