Answer:
w=30 l=125
Step-by-step explanation:
Perimeter =2l+2w
p=310
w =width
4w+5 = length(4 times plus 5 the width)
2(4w+5) + 2w = 310
8w+10 = 2w =310
10w=300
w=30
30*4=120 120+5=125 l=125
2(125)+ 2(30)= 250+60 =310
The buyer will be paying taxes for 185 days, so will pay
... (185/365)·$8200 = $4156
Your most appropriate choice seems to be $4178, which corresponds to 186 days' taxes.
_____
There are 30 days in each month in the last half of the year, plus 1 additional day in each of July, August, October, and December. The 30th of June also belongs to the buyer (but the 29th, closing day, does not), so there are 180+5 = 185 days for which the buyer must pay taxes. The answer choices don't include that value.
Answer:
m = 6
Step-by-step explanation:
Here, we want to find the value of m
To do this, we use the indices addition property for multiplication
On the left hand side;
5^(2 + m + 7) = 5^15
5^(m + 9) = 5^15
since the bases are equal, we equate the powers
m + 9 = 15
m = 15-9
m = 6
