8)Reduce a las unidades indicadas: a)18 cm 3 a dm 3
lys-0071 [83]

Answer:

(a) 0.018 dm^3

(b) 20 x 10^15 ml^3

Step-by-step explanation:

a) 18 cm^3 to dm^3

1 cm = 0.1 dm

So,

1 cm^3 = 0.001 dm^3

So, 18 cm^3 = 18 x 0.001 dm^3 = 0.018 dm^3

b) 20 hl^3 to ml^3

1 hl = 100000 ml

So, 1 hl^3 = 10^15 ml^3

So,

20  hl^3 = 20 x 10^15 ml^3.

Please help me!!! Its math and I am struggling
Romashka-Z-Leto [24]

Answer:

16:36 = 32:72 = 12:27

Step-by-step explanation:

An easy way for me to solve this is to divide the first value by the second. If they turn out to be the same fraction, then they are equivalent.

Is 16:36 = 32:72?

Yes, because \frac{16}{36}=\frac{4}{9} =\frac{32}{72}

Is 16:36 = 12:27?

Yes, because \frac{16}{36}=\frac{4}{9} =\frac{12}{27}

Is 16:36 = 3:4?

No because \frac{16}{36}=\frac{4}{9} \neq \frac{3}{4}

I hope this helps!!! Please rank if it does and let me know if you have any more questions about this!

Challenge:
bonufazy [111]

The trick here is that both times, part of the weight is soup
and part of the weight is the empty metal can.

1/2 soup + MTcan = 5
1/3 soup + MTcan = 4

Before going any further, it will make it a lot easier later if we change
the fractions in both equations to a common denominator:

1/2 = 3/6
1/3 = 2/6

3/6 soup + 1 MTcan = 5
2/6 soup + 1 MTcan = 4

Subtract the 2nd equation from the 1st one:

1/6 soup = 1

Multiply each side by 6 :    <u>1 soup = 6</u>

Substitute this in the first equation:

             1/2 soup + 1 MTcan = 5

             1/2  ( 6 ) + 1 MTcan = 5

                       3  + 1 MTcan = 5

Subtract 3 from each side:  <u>1 MTcan = 2</u>

The empty can weighs 2.
All the soup it can hold weighs 6.

A full can of soup weighs (2 + 6) = <em><u>8</u></em>
