One of them is 3,8,3,8 and the other is 4,6,4,6
Answer:
x = 27
Step-by-step explanation:
Since AC and DE are parallel lines, then
∠ BAD = ∠ EDF= 2x ( corresponding angles )
The sum of the 3 angles in Δ BAD = 180°, thus
2x + 2x + 72 = 180, that is
4x + 72 = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
Answer:
3.5 un
Step-by-step explanation:
to find the new length of the square using a scale factor of 1/7 you can just multiply 24.5 by 1/7
this is basically dividing 24.5 by 7
24.5 / 7 = 3.5
that is your answer
Answer:
300%
Step-by-step explanation:
Here we have an exponential function, 
and it is one of the most important functions in the mathematics. In this case, the independet variable is the exponent.
Here we have that represented price increase of 13% each year, which means that 
in our exponential function, while 
represent the journal price at the begining.
So we get the following function:
where 
represents number of years. After 10 years, we get:
The conclusion is that over 10 years, the percentage of increase would be about 300%.
