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
