you deposited 8500 dollars in a savings account that earns a simple interest rate what interest rate do you need to be paid if y
anzhelika [568]

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

t=5\ years\\ P=\$8,500\\ A=\$10,093.75\\r=?

substitute in the formula above

10,093.75=8,500*(1+r*5)

solve for r

5*r=(10,093.75/8,500)-1

r=0.0375

r=3.75\%

therefore

<u>the answer is</u>

the rate of interest is 3.75\%

The area of the base of a rectangular prisim four and three fourths and the height of two and one third what is the volume
VikaD [51]
Data:
A_{base} = 4 \frac{3}{4} = \frac{4*4+3}{4} = \frac{16+3}{4} \to A_{base} = \frac{19}{4}

h (height) = 2 \frac{1}{3} =  \frac{3*2+1}{3} = \frac{6+1}{3} \to h (height) = \frac{7}{3}
v (volume) = ?

Formula: V =  A_{b}*h

Solving:
V = A_{b}*h
V =  \frac{19}{4} * \frac{7}{3}
V =  \frac{133}{12}
V = 11.08333....
\boxed{\boxed{V \approx 11.08}}\end{array}}\qquad\quad\checkmark
