Hello.

Yes, it is geometric and the ratio is 3/4.  You can tell because you can divide each one by the one before and you get 3/4.  (3/16)/(1/4)=3/4, (9/64)/(3/16)=3/4, and so on.

Have a nice day

If 24 bags of sugar with equal weight weigh 21 kg, how many bags of sugar would weigh 122kg?​
aleksandrvk [35]

Answer:

24 bags = 21 kg

1.142 bag = 1 kg

About 139 bags = 122 kg

You start off with 24 bags that equal the same amount as 21 kg. You need to find out how many bags of sugar equal the same amount as 122 kg. The first line is a ratio and to find your answer you need to figure out what is 1 kilogram equal to in the amount of bags. You divide both sides by 21 leaving 1.142 bag equal to 1 kilogram. In order to find 122 kilograms, you have to multiply both sides by 122 kilograms which would give you about 139 bags = 122 kilograms.  

Your final answer: 139 bags

I hope this helped!

Alex

Answer:

R = 6S/T

Step-by-step explanation:

R ∝ S/ T

》R = kS/ T

》k = RT/ S

If R = 8 when S = 4 and T = 3

then, k = (8 × 3)/ 4

k = 6

∴ R = (6 × S)/ T

Answer:

Yes, They are similar by SSS PMK similar to LMQ.

Step-by-step explanation:

Similar triangles corresponding side lengths are in a proportion.

KM corresponds with MQ

PM corresponds with LM.

Set up this proportion.

\frac{km}{pm}  =   \frac{lm}{mq}

\frac{15}{28}  =  \frac{21}{39.2}

Cross multiply

588 = 588

So the triangles ARE Similar.

  • PM corresponds with LM
  • KM corresponds with MQ
  • PK corresponds with LQ
  • So PMK is similar to LMQ
