for 1 year, I earn $40

Answer: 2.5 years

Step-by-step explanation:

The formula to calculate the simple interest is given by :-

I=Prt, where P is the principal amount , r is the rate of interest ( in decimal) and t is time ( in years).                                              

Given : P= $800   ; r= 5% =0.05   and  I=$100

Then , we have

100=800\times0.05t\\\\\Rightarrow\ t=\dfrac{100}{800\times0.05}=2.5

Hence, you must leave the money in the account for 2.5 years to earn $100 in interest.

A solid right pyramid has a regular hexagonal base with an area of 7.4 units2. The pyramid has a height of 6 units.
Lelechka [254]

Answer: Second option.

Step-by-step explanation:

You need to use the following formula:

V=\frac{1}{3}Bh

Where "B" is the area of its base and "h" is the height.

According to the data given in the exercise, you know that:

B=7.4 units^2\\\\h=6\ units

Therefore, knowing this values, you can substitute them into the formula shown before and then evaluate, in order to calculate the volume of thi right pyramid whose base is a regular hexagon.

Then, you get:

V=\frac{1}{3}(7.4 units^2)(6\ units)\\\\V=14.8\ units^3
