Answer:
His sister sent 6 more messages than Diego.
Step-by-step explanation:
Ratio of Diego's messages to his sister's messages = 3 : 4
Text messages sent by Diego = 18
Text messages sent by his sister = x
Ratio = 18 : x
It is a proportional relationship,
3 : 4 :: 18 : x
Product of extremes = Product of means
3x = 18*4
3x = 72
Difference = 24 - 18 = 6
Therefore,
His sister sent 6 more messages than Diego.
It is a 40.5% increase, how I got my answer.
It is really simple, all I done was added $2,990 and on a caculater started at 100% increase would be 5,980, the reason I started out with 100% is because it is much easyer to judge how much I need to go down or up in percentage, so I knew that I needed to find $4,200, so I moved it down to 45% which equaled $4,335.5 so I brought it down to 41% which equals $4,215.9, so I brought it down to 40% which equals $4,186, then I brought it up to 40.5% which equals $4,200.95, but the .95 does not matter.
I hope this helps!
Answer:
Step-by-step explanation:
By geometric mean theorem,
In a triangle ABC,
y² = 60
y = √60
y = 7.75
Similarly, 
x² = 40
x = √40
x = 6.32
