Let's equate the congruent sides.

\begin{gathered} 9r-6=8r+3 \\ r=9 \end{gathered}

Now, the segment EF is equal to the segment CD:

Orion is constructing a rectangular box. The base of the box is a piece of wood with an area of 90 square inches. The volume of
gladu [14]

The volume of a rectangular prism is the product of the three dimensions.

The width and length give the base area,  which is 90.

So, if we multiply the base area and the height, we get the volume:

w\cdot l\cdot h = V \implies h = \dfrac{V}{w\cdot l}

We know that V=1080 and w*l (i.e. the base area) is 90. So, we have

h=\drac{1080}{90}=12

How much must be deposited today into the following account in order to have $ 50,000 in 6 years for a down payment on a​ house?
Charra [1.4K]

Answer:

The Amount initially deposited is $37046.64

Step-by-step explanation:

A = p (1+r/n)^(nt)

A= final amount= $5000

P = principal amount=

r = rate = 0.05

n = number of times compounded

= 6*12

= 48

t = years= 6

A = p (1+r/n)^(nt)

50000 = p (1+0.05/48)^(48*6)

50000= p(1.001041667)^288

50000= p (1.34965)

50000/1.34965= p

37046.64 = p

The Amount initially deposited is $37046.64
