Answer:

the ending balance is <em>$190</em>.

Step-by-step explanation:

Step 1:

The given information is:

Interest rate = 3% per year

Beginning balance = 150 $

Equation:

t = log₁.₀₃ (E / 150)

Step 2:

Solve for E:

8 = log₁.₀₃ (E / 150)

E / 150 = (1.03)⁸

E = (1.03)⁸ (150)

<em>E = 190 $</em>

<em></em>

Therefore, the ending balance is <em>$190</em>.

Length of a rectangle is 5 cm longer than the width. Four squares are constructed outside the rectangle such that each of the sq
TiliK225 [7]

Answer:

The perimeter of rectangle is 18\ cm

Step-by-step explanation:

Let

x-----> the length of the rectangle

y----> the width of the rectangle

we know that

x=y+5 ----> equation A

120=xy+2x^{2}+2y^{2}  ---> equation B (area of the constructed figure)

substitute the equation A in equation B

120=(y+5)y+2(y+5)^{2}+2y^{2}

120=(y+5)y+2(y+5)^{2}+2y^{2}\\ 120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\ 120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\120=5y^{2}+25y+50\\5y^{2}+25y-70=0

using a graphing calculator -----> solve the quadratic equation

The solution is

y=2\ cm

Find the value of x

x=y+5 ----> x=2+5=7\ cm

Find the perimeter of rectangle

P=2(x+y)=2(7+2)=18\ cm

Step One 
Find the Volume in ccs.

V= l*w*h
l =40 mm
w = 25 mm
h = 2 mm
V = 40*35 * 2
V = 2800 mm^3

Step Two
Find the weight
1  mm^3 = 0.0005
2800 mm^3 = x   <<<<< answer 1

\frac{1}{2800} =  \frac{0.0005}{x}   Cross multiply.

1x = 2800 * 0.0005
x = 1.4 ounces.  <<<<< answer 2
