The answer is "<span>the number of times the account compounds interest</span>".
The general formula is the following:
3,545(1+r)^n
wherein r is the interest rate compound each four months. 
Since there is 3*4 months in a year, then each year we compute the interest Three time, there where the factor 3 comes.

Ben is standing 8 feet from
never [62]

Answer:

Approximately 15.05 ft

Step-by-step explanation:

You need to use tangent for this question.

Since tan θ = \frac{Opposite}{Adjacent}

to find the Opposite, we need to rearrange the equation to:

Adjacent × tan θ = Opposite.

So if you insert 62 for θ and 8 feet for Adjacent, you will get:

8 × tan(62) = Opposite.

and you will get approximately 15.05 feet for your Opposite side

Find indicated values: m AB = m ABC = m BAC = m ACB =
FinnZ [79.3K]
AB
 It is indicated in the figure and is valid:
 m AB = 49
 m ABC
 Angle resulting from the following subtraction:
 m ABC = 360-107 = 253
 m BAC
 
Angle resulting from the sum of the two angles shown in the figure:
 m BAC = 107 + 49 = 156

 m ACB 
 Angle resulting from the following subtraction:
 m ACB = 360-49 = 311

Are the expressions x + x + 1 + x + 2 + x + 1 + x and 5x + 4 equivalent? Why or why not?
egoroff_w [7]

Answer:

yes

they are equivalent because lets say the X = 3 then you would have to answer

3 + 3 + 1 + 3 + 2 + 3 + 1 + 3

and that would = 19

and then on the other equation

5 x 3 + 4 = 19

So the both equal the same.

What is the cost of constructing a fence 6 feet, 6 inches, high around a lot measuring 90 feet by 175 feet, if the cost of erect
boyakko [2]

Answer:

The total cost is  $3,504.63

Step-by-step explanation:

Length of fence = 90 feet

Breadth of fence = 175 feet

Height of fence = 6 feet, 6 inches

1 inch = 0.0833333 feet

6 inches = 6*0.0833333 =0.4999998  feet

So, Height of fence = 6 feet + 0.49 feet =6.49 feet ≈ 6.5 feet

Perimeter = 2(Length \times breadth)=2(90 +175) = 530 feet

Cost of erecting the fence is $1.25 per linear foot

So, Cost of erecting the fence in 530 feet = 530 \times 1.25 = 662.5

Total surface area = 2(length +breadth) Height =530 \times 6.5=3445ft^2

The cost of materials is $0.825 per square foot of fence

Cost of material for 3445 sq.feet = 3445 \times 0.825 =2837.7525

So, total cost = 2842.125+662.5 = 3504.63

Hence The total cost is  $3,504.63
