Make a ratio, then cross multiply.
4/30=x/48
30x=4x48
30x=192
x=6.4

Answer:
Step-by-step explanation:
Given that a car mechanic rounds a car's weight to the nearest thousand
By rounding off to nearest 1000, we mean we look at the last three digits. If these digits are 500 or greater, then we round the thousands digit up, and if they are less than 500, then we round down, keeping the thousand's digit the same.
To simplify the above we can say the 100th digit if greater than or equal to 5, we round off the 1000th digit by 1 up otherwise leave it as it is
Example, 18765 is rounded off as 19000 while
15462 is rounded off as 15000
Here the answer after rounding off is 4000
This is possible if the weight was atleast 3500 because in this case he would round off to 4000 or highest 4499.
If 3499 or 4500 the rounding off would not have been 4000
So least number is 3500 and greatest number is 4499.
Answer: anyway i hope this will help
If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar. Corresponding sides of similar polygons are in proportion, and corresponding angles of similar polygons have the same measure.
Step-by-step explanation:
Formal notation. The wavy line symbol means 'similar to'.
Rotation and reflection. Polygons can still be similar even if one of them is rotated, and/or mirror image of the other. In the figure below, all three polygons are similar.
Answer:
(a) The recurrence relation for the salary is
(b) The salary 25 years after 2017 will be $217044.85.
(c) 
Step-by-step explanation:
We can define the next year salary 
as
wit S0=$50000
If we extend this to 2 years from 2017 (n+2), we have
Extending to 3 years (n+3)
Extending to 4 years (n+4)
We can now express a general equation for S_n (salary at n years from 2017)
The salary at 25 years from 2017 (n=25) will be
