Answer:

3n−32=7n+28

n=-15

Step-by-step explanation:

Let's solve your equation step-by-step.

3n−32=7n+28

Step 1: Subtract 7n from both sides.

3n−32−7n=7n+28−7n

−4n−32=28

Step 2: Add 32 to both sides.

−4n−32+32=28+32

−4n=60

Step 3: Divide both sides by -4.

−4n/−4=60/−4

n=−15

Apparently, the calculator at the link in your lesson is fully capable of giving you the necessary numbers. My own TI-84 work-alike gives me the account balances, but the rest of the numbers need to be figured.

In 30 years, there are 12×30 = 360 months, or 4×30 = 120 quarters. See the calculator results below. Your table can be filled in using the given information to find the contribution amount. The calculator gives the final balance. The interest amount is found by subtracting the contribution amount from the final balance.

\begin{array}{cccc}\text{Opt}&\text{Contributions}&\text{Int}&\text{Final Bal}\\1&360\cdot 25=9000&6250.50&15250.50\\2&120\cdot 75=9000&8467.04&17467.04\\3&1000&5489.17&6489.17\end{array}

Answer: 29544.26 mm^2

Step-by-step explanation:

The formula is A = pi R squared.

Answer:

FGE = 180 - (14 + 78)°

= 88°

so angle GEC = 88°

4x + 88 = 180

4x = 180 - 88

4x = 92

x = 92/4

= 23

A cable is installed around two edges of the rectangular field that is 860 feet long and 340 feet wide, as shown below. Suppose
raketka [301]

Answer:

<em>a. 2,520,000.00</em>

<em>b. $1,942,017.51</em>

<em>c. $577,982.49</em>

Step-by-step explanation:

<u>Distances in a Rectangle</u>

a.

Running the cable along the edges of the field would need a total length of 860 ft + 340 ft = 1,200 ft of cable. The unit cost of the cable is $2,100 per foot, thus the cost of the total lenght of cable was 2,100*1,200= $2,520,000.

b. If the cable ran along the diagonal, the distance must be computed by

D=\sqrt{x^2+y^2}

where x = 860 ft and y = 340 ft, thus

D=\sqrt{860^2+340^2}=924.77

D = 924.77 ft. The cost of the cable would be 2,100*924.77= $1,942,017.51

c. The savings if the cable were installed along the diagonal of the field instead of around the edges of the field would be

$2,520,000 - $1,942,017.51 = $577,982.49
