Answer:
145 + 33n
Step-by-step explanation:
Let
n = number of members in the club
Day 1:
Cost = 50 + 18n
Day 2:
Cost = 95 + 15n
Total cost two-day field trip = day 1 + day 2
= (50 + 18n) + (95 + 15n)
= 50 + 18n + 95 + 15n
= 145 + 33n
Total cost two-day field trip = 145 + 33n
An expression that represents the total cost in dollars for two days for the n members of the club is given by 145 + 33n
The 3rd one (One liter) is the best value.
Answer:
Area = 87.9646 sq. units from A = 28*π sq. units.
However I cannot see this in your answer list, since the numbers look all jumbled. Choice A. looks close to it, since there is a 28...
Step-by-step explanation:
We have a cylinder with height h = 5
radius = 2
We want the surface area of this cylinder.
A = (circumference)*h + 2*(pi)*r^2
A = ( 4*π)*5 + 2*π*(2^2)
A = 20π + 8π = 28 π square units
A = 87.9646 sq.. units
Answer:
5 inches
Step-by-step explanation:
Given
Length of a cube = 1 inch
Required
Determine the edge length of the cube
If the container can take 125 cubes, then that's the volume
So:
Volume of a cube is calculated as thus;
This gives;
Take cube root of both sides
![Length = \sqrt[3]{125}](https://tex.z-dn.net/?f=Length%20%3D%20%5Csqrt%5B3%5D%7B125%7D)
Hence, the length is 5 inches
