What is the percentage change from 305 to 395
Troyanec [42]

Answer:

29.51%

Step-by-step explanation:

The change from 305 to 395 is the difference between the two numbers. So, it would be 395 - 305 or 90. Now, to find the percentage of change, we need to find what part of the original amount is the change. In other words, we would have to divide 90 by 305. By putting this in a calculator you get about 0.2951. To convert this decimal into a percent, we would multiply by 100 giving us 29.51%.

PLEEEEASEEEE HELP ASAP its an emergency,,,, WILL MARK BRAINLIEST
AleksAgata [21]
____ heya mate_____


here is full solution


John's payments are
month 1: $100
month 2: $100*(1.1)
month 3: $100*(1.1)²
month 4: $100*(1.1)³

...

The payments form the geometric sequence 
a, ar, ar², ..., arⁿ
where
a = $100
r = 1.1

The sum of the first n terms is


Therefore the sum of the first 20 payments is
S₂₀ = [$100(1 - 1.1²⁰)]/(1 - 1.1)
     = $5727.50

John makes a total of $5727.50 in the first 20 payments.



HOPE THIS WILL HELP U!!,!!! :-) :-) :-) :-) :-)

Hi, can someone help explain this. (Triangle similarity/10th grade)
scZoUnD [109]
This is one proportion that can be created from the given information \frac{36}{24} = \frac{6x-6}{3x+7}.

You would then use cross product to solve it. Also reduce 36/24 to 3/2
3(3x + 7) = 2(6x - 6)
9x + 21 = 12x - 12
33 = 3x                   I subtracted 9x from both sides and added 12 to both sides
11 = x
