Divide 240g in the ratio 5:3:4​
Nastasia [14]

Answer:

240g in the ratio of 5:3:4

So we need to divide it evenly.

First add up all the ratios.
5+3+4= 12

Now divide 240 by the sum.

240/ 12 = 20

Now you multiply that into each ratio.

5*20 = 100

3*20 = 60

4*20 = 80
Now put it back in the ratio with the new numbers int he exact order as before.

Final Answer: 100 : 60 : 80

Check:

You can check by adding them all up to see if they all go into 240 OR you can divide them each by the number originaly given and you should get 20.

100 + 60 + 80 = 240

100 / 5 = 20

60/3 = 20

80/4 = 20

Identify which line from the graph the following right triangles could lie on.
qaws [65]

Answer:

Step-by-step explanation:

Slope of line A = \frac{\text{Rise}}{\text{Run}}

                         = \frac{9}{3}

                         = 3

Slope of line B = \frac{9}{6}

                         = \frac{3}{2}

Slope of line C = \frac{6}{8}

                         = \frac{3}{4}

5). Slope of the hypotenuse of the right triangle = \frac{\text{Rise}}{\text{Run}}

                                                                                = \frac{90}{120}

                                                                                = \frac{3}{4}

Since slopes of line C and the hypotenuse are same, right triangle may lie on line C.

6). Slope of the hypotenuse = \frac{30}{10}

                                              = 3

Therefore, this triangle may lie on the line A.

7). Slope of hypotenuse = \frac{18}{24}

                                        = \frac{3}{4}

Given triangle may lie on the line C.

8). Slope of hypotenuse = \frac{21}{14}

                                        = \frac{3}{2}

Given triangle may lie on the line B.

9). Slope of hypotenuse = \frac{36}{24}

                                        = \frac{3}{2}

Given triangle may lie on the line B.

10). Slope of hypotenuse = \frac{48}{16}

                                          = 3

Given triangle may lie on the line A.
