Point D is the in center of triangle ABC. Write an expression for the length x in terms of the three side lengths AB, AC, BC.
mina [271]

Answer:

\underline{\boxed{x =  \frac{A_r}{AC}}}

Step-by-step explanation:

let \: the \: area \: be \to \: A_r \\  since \: the \: base =AC \\ then \: the \: height = AB \\ but \: AB = 2x \\ hence : the \: area \: A_r=  \frac{1}{2} AC(2x) \\ (2x)AC = 2A_r\\ x =  \frac{2(A_r)}{2(AC)}  \\  \boxed{x =  \frac{A_r}{AC}}

Jayden earned some money doing odd jobs last summer and put it in a savings account that earns 12% interest compounded monthly.
aivan3 [116]

Answer:

$220.18

Step-by-step explanation:

The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:

A(n)=P \left(1+\dfrac{r}{k}\right)^{nk}

In Jayden's case:

  • A(n)=$400
  • r=12%=0.12
  • n=5 years
  • k=12 Months

We want to determine the amount Jayden put in the savings account.

400=P \left(1+\dfrac{0.12}{12}\right)^{12*5}\\400=P \left(1+0.01}\right)^{60}\\400=P \left(1.01}\right)^{60}\\P=\dfrac{400}{\left(1.01}\right)^{60}}\\

P=\$220.18

Jayden earned $220.18 from doing odd jobs.

Leona [35]

Answer:

Step-by-step explanation:

The question doesn't make sense. There is no way receipts could have totaled $8008.50. The most that could have been taken is if all 430 of the patrons were adults. That gives 430×2.25 = $967.50
