Answer:
It will take 35.12 years for the account to reach $7,600.
Step-by-step explanation:
Holly invests money, P=$600
Interest rate,r= 7.5%
Amount money,A =$7,600
We know that the formula to obtain the amount
Where A= Amount money
P= Principle value
r= Interest rate
t= time in years
By using this formula
Taking both side logarithm then we get
1.5798-0.4771=
By substituting value from log table
1.1027=
By simplification
By division property of equality
t=35.117 years
t=35.12 years ( nearest hundreth place)
Hence, it will take 35.12 years for the account to reach $7,600.
Answer:
Step-by-step explanation:The prism has 9 edges; the bases of the prism are triangles; and the prism has 5 faces.
Step-by-step explanation:
The bases of a prism are the faces that are parallel. In this prism, the only faces that are parallel are the two triangles. This means the bases are triangles.
In addition to the two parallel bases, there is a are three faces that join the sides of the bases. This makes a total of 2+3 = 5 faces.
The edges are where the faces meet. There are 3 edges around each base; this is 6. There are also 3 edges connecting the lateral faces; this makes 6+3 = 9 edges.
