Answer:
121€
Step-by-step explanation:
;)
X = pay and y = hours worked
direct variation equations are of the form:
dependent variable = k(independent variable)
we need to find k, the constant of variation
x = ky
49.40 = 6.5k
7.6 = k
EQUATION: x = 7.6y
PAY for 25 hours: x = 7.6(25) = 190 or $190
A(n)=ar^(n-1) and we can find the rate upon using the ratio of two points...
50/1250=1250r^2/1250r^0
1/25=r^2
r=1/5 so
a(n)=1250(1/5)^1=250
...
You could have also found the geometric mean which is actually quite efficient too...
The geometric mean is equal to the product of a set of elements raised to the 1/n the power where n is the number of multiplicands...in this case:
gm=(1250*50)^(1/2)=250
If you would like to write 0.097 in fractional notation, you can do this like this:
0.097 = 97 / 1000
The correct result would be <span>A 97/1000.</span>
Add all the item together:
16 + 28 + 12 + 4
=60 total items
