What is the cost of constructing a fence 6 and a half feet (6'6") high around a lot measuring 90 ft by 175 ft; if the cost of er

creativ13 [48]

Based on the given values, I can only assume that the fence forms a rectangular shape. With this, the perimeter of the lot is:

Perimeter of lot = 2 * 90 + 2 * 175

Perimeter of lot = 180 + 350

Perimeter of lot = 530 feet

Since the cost per linear feet (perimeter) is $1.25, therefore the cost of erecting the fence is:<span>
Cost of erecting fence = $1.25 * 530 </span>

Cost of erecting fence = $662.50

The area of the fence would be equal to the perimeter multiplied by the height:<span>
Area of fence = 530 feet long * 6.5 feet high </span>

Area of fence = 3445 square feet

Then the cost of materials will be:<span>
<span>Cost of materials = 3445 * $.825 </span></span>

Cost of materials = $2,842.13

Therefore the total cost would be: <span>
<span>Total cost = $662.50 + $2,842.13 </span></span>

<span>Total cost = $3504.63</span>

Use the substitution method to solve the system of equations choose the correct ordered pair

Gekata [30.6K]

Answer:

C. (4,28)

Step-by-step explanation:

The substitution method requires you to input a specified number in place of a variable. In this case, the variable 'x' should be replaced by the number 4. Using the order of operations, we know that multiplication should be applied before subtraction. When we replace 'x' with 4, we get the equation 'y=8(4)-4'. Multiplying 8 and 4 gives us 32. If we subtract 4 from 32, we get 28. The answer ends up being 'y=28'.

That is the first part of our solution. What we are actually looking for is an ordered pair. We know ordered pairs are written in the form (x, y). First, we need to find the 'x'. The 'x' has been given to us from the beginning, it is 4. Next is the 'y'. This is what we needed to find using substitution. We ultimately concluded that the 'y' is equivalent to 28. Therefore our ordered pair is (4, 28), the letter choice C.

I hope this helped you and that I clearly elaborated on the answer choice.

Answer:

59049

1 / 59049

Step-by-step explanation:

for five digit pin

five blank spaces are there to fill

as repetition is allowed every blank space has 9 possible digits to fill

so total ways = 9 * 9 * 9 * 9 * 9 = 9^5 = 59049

so probability is 1 / 59049 as there is only one correct code
