Mamont248 [21]

Answer: 12.3 ft.

Step-by-step explanation:

In the given picture we can see there is a right triangle with hypotenuse 15 ft.

Using trigonometry in the given right triangle, we have

\cos35^{\circ}=\frac{\text{Side adjacent to}\ 35^{\circ}}{\text{Hypotenuse}}\\\\\Rightarrow\ 0.81915204428=\frac{A}{15}\\\\\Rightarrow\ A=0.81915204428\times15\\\\\Rightarrow\ A=12.2872806642\approx12.3\ ft.

Hence, the  length of rope A = 12.3 ft.

A bank manager wants to encourage new customers to open accounts with initial deposits of at least $3000. He has posters made fo
belka [17]

Incomplete question. However, let us assume

  • the interest rate is 5%, and
  • the time is 1 year.

Answer:

<u>$150</u>

Step-by-step explanation:

Note, the bank manager wants new customer accounts opened with at least, $3,000. Hence we have a principal, $3000. Using the simple interest formula:

S.I= \frac{amount*rate*time}{100}

SI=\frac{3000*5*1}{100} = $150

Therefore, the <em>minimum</em> amount of interest a new account would make in one year is <u>$150.</u>
