Answer:(2,-9)
Step-by-step explanation:
Total area is 30 by 50 feet=1500 ft^2
So per square foot charges are 2.99$ and 200 additional
1500×2.99+200=4685$
And another charging 19.99$ per square yard
1 yard = 3feet
30 feet=10 yard
50 feet=50/3 yard
Area=50/3×10=500/3=166.66yards^2
So they will charge 166.66×19.99=3331.66+500= 3831.66$
So comapny B is cheaper and best deal
Answer:
Answer is below
Step-by-step explanation:
21 + 5f = 61 Turn the words into an equation
-21 - 21 Subtract 21 from both sides
5f = 40 Divide both sides by 5
f = 8

The formula in getting the arithmetic sequence:
an = a1<span> + (n – 1)d.
</span>
We can substitute the values in order for us to know how many terms the sequence has.
an = 7373
a1 = 1313
d = 303
an = a1<span> + (n – 1)d
</span>7373 = 1313 + (n-1) 303
7373 = 1313 + 303n - 303
-303n = 1313 - 303 - 7373
303n = -1313 + 303 + 7373
303n = 6363
n = 21
So, there are 21 terms in the sequence given.
