Answer:
Annual Cost of Rent: $725*12=8700
Add: Renter's Insurance=$275
Total Cost=$8,975
Now if she purchased a house then let's see how much annual cost she need to bear:
EMI=$185000-$10,000=$175000/Total PVIF @5% for 30Years
EMI=$939.44
Hence. Annually it would be $939.44*12=$11273.28
So, it is quite clear that by purchasing the owned home Emma needs to bear extra cost of $2298.28 per year apart from the yearly expenditure that is property taxes insurance and maintenance which is of 10% of total cost of the house that is $18,500($185000*10%).
Hence, to purchase a house is not feasible and to go for the rent option is more viable for Emma.
The perimeter solved shows that the dimensions of the rectangle are 32 and 10.
<h3>How to calculate the perimeter</h3>
Let the width be w
Length = 3w + 2
Perimeter = 2(length + width)
Perimeter = 2(3w + 2) + 2w
6w + 4 + 2w = 84
8w + 4 = 84
8w = 84 - 4
w = 80/8
w = 10
Length = 3w + 2
Length = 3(10) + 2
Length = 32
The dimensions of the rectangle are 32 and 10.

Since it is a given that the angles are vertical, then that means they have to be congruent or = to each other so we can now set up an equation:
3x+7=x+53
Now we need to get the variable alone on one side so subtract 7 from the left (remember what you do, you must do to both sides)
3x=46
Now we can divide by three to get x alone
x=15.333333333 or rounded to 15.33
13.15 ounces of 72% acid and 71.85 ounces of 25% acid are needed
<u>Step-by-step explanation:</u>
Total mass of acid required= 85 ounces
Let the mass of 72% acid be 'a'
Let the mass of 25% acid be 'b'
a + b = 85
b = 85-a
85(40/100) = a(72/100) + b(25/100)
85(2/5) = a(72/100) +(85- a) (25/100)
34 = (72a/100) + (2125/100) - (25a/100)
34 - (2125/100) = (72a + 25a) /100
(3400-2125)/100 = 97a /100
97a = 1275
a = 13.15 ounces
b = 85 - 13.14
b = 71.85 ounces
13.15 ounces of 72% acid and 71.85 ounces of 25% acid are needed
