Answer:
14.8%
Step-by-step explanation:
Given data
Initial income=47
Final income=40
The change= 47-40
=7
Hence the percent increase is
% increase= Change/ initial*100
% increase= 7/47*100
% increase=0.148*100
% increase=14.8%
4(xsquared -2) thats the answer
This would depend on if we assume this is constant or exponential growth. If it is linear then it would be:
600=3m+300
300=3m
100=m
A=100d+300
A(12)=1500 mi^2
If it is exponential:
600=300r^3
2=r^3
r=2^(1/3)
A=300(2)^(d/3)
A(12)=4800 mi^2
Answer:
37.5 degrees
Step-by-step explanation:
there are two isoceles triangles. we know that an isoceles triangle has 2 congruent angles. since we know that the first angle is 75 degrees, we subtract 75 from 180 (since the three angles of a triangle add up to 180). Then, we take the difference (105) and divide it by 2 to get 52.5. since we know x and the angle we just found (52.5) are complimentary, we subtract 52.5 from 90 to get x = 37.5 degrees.
