If the cost of one pen is x, the Sasha spend 3x, and Malachi spent 1x.
Sahsa spend 3x - 1x more than Malachi. So, Sasha spent 2x more than Malchi did for a pen.
Just plug in how much a pen costs into x to fi d the numerical answer. :)
Answer:
First one: 5x3(0.75)2t
and fourth one: 0.05x500(0.005)t
Step-by-step explanation:
In order to have an exponencial decay, the rate of the exponencial function needs to be lesser than 1.
The rate is the value between parenthesis, so in the first equation, the rate is 0.75, so this is an exponencial decay.
The second equation has rate = 2.4, so this is not an exponencial decay.
The third equation has rate = 1.04, so this is not an exponencial decay.
The fourth equation has rate = 0.005, so this is an exponencial decay.
Answer:
261.8 in^3
Step-by-step explanation:
The formula for the volume of a cone is V = (1/3)(base)(height), where "base" is the area of the base.
In this case, with the radius being 5 in and the height 10 in, we get:
V = (1/3)*π*(5 in)^2*(10 in), which simplifies to 261.8 in^3.
To find the perimeter you need to add all 3 sides
