Answer:

7/14 and 20/40 are proportional.

Step-by-step explanation:

We're looking for the pairs of ratios where the two ratios are equal.

6/21 and 2/42 are not equal, although 6/21 and 12/42 would be equal.

25/100 and 50/150 are not equal.

18/24 and 6/12 are not equal. Notice that dividing 18 and 24 by 6 results in 3/8, which does not equal 6/12 or 3/6 or 1/2.

In the last case, notice that 7/14 = 1/2 and 20/40 = 1/2. This pair of fractions is proportional. Note that 20/7 times 7 is 20 (the numerator of the 20/40), and that 20/7 times 14 is 40. The constant of proportionality is thus 20/7.

Candy and Tim share a paper route. It takes Candy 85 min to deliver all the papers, and it takes Tim 65 min. How long does it ta

RSB [31]

Answer:

The time required to finish the work by both candy and Tim working together = 36.83 minute

Step-by-step explanation:

Time taken by the candy to finish the work $T_{1}$ = 85 min

Time taken by the Tim to finish the work $T_{2}$ = 65 min

Thus the time taken by both to finish the work = $\frac{T_1 \times\ T_2}{T_1 + T_2}$

Put the values of $T_{1}$ and $T_{2}$ we get ,

$T_{}$ = $\frac{85 \times\ 65}{85 + 65}$

$T_{}$ = $\frac{221}{6}$

$T_{}$ = 36.83 minute

Thus the time required to finish the work by both candy and Tim working together = 36.83 minute

A man notices that a tank is half full. After emptying 600 litres from the tank, that it is now one-third full. How much does th

enot [183]

One half is equal to 3/6.
One third is equal to 2/6.

After removing 600 litres from the tank, there is a decrease from 3/6 to 2/6

3/6-2/6=1/6

600 litres is 1/6 of the tank. Multiply by 6 to get the capacity of a full tank.

600*6=3600

The tank can hold 3600 litres.

Figure B is a scaled copy of Figure A.

elixir [45]

Answer:

The scale factor would be 1/2.

Step-by-step explanation:

2 of the sides both are 4 units.

If you go to figure B, it got smaller.

So in this case, you would divide.

On figure B, 2 of the sides are 2 units.

If you did it in reverse, you would get 2 because 2 times 2 is 4.

But we divide, so 4/2 is 2, so the scale factor would be:

1/2

Hope this helped!

And brainliest pls :)
