Answer:
12 ×$0.75 =$8.00
3.75 ÷ 5 = $1.33 a pound,
$1.33 × 12 = $15.96 so store A is offering the best rate.
A = Area
x = Side Parallel to the river.
Which in your context results to:
Area = 1250 yards squared
Answer ; 242 cm because 418/3.8 =110 and if you multiply 110 with 2.2 you’ll have 242 !!
The surface area of the cone is calculated to the nearest tenth as: 173.4 cm².
<h3>What is the Surface Area of a Cone?</h3>
Surface area of a cone = πr(r + l),
Given the following:
- Radius (r) = 4 cm
- Slant height (l) = 9.8 cm
Plug in the values
Surface area of the cone = π × 4(4 + 9.8)
Surface area of the cone = 173.4 cm²

Answer:
5,120 bacterias
Step-by-step explanation:
Given the amount of bacteria after x hours modelled by the equation:
f(x) = 20(2)^x/12
Note that x is in hours not days
To calculate the number of bacteria that will be contained within the culture after 4 days, we will first convert 4days into hours since x is in hours.
24hours = 1day
xhours = 4days
x = 24×4
x = 96hours
Substituting x = 96 into the equation
f(96) = 20(2)^96/12
f(96) = 20(2)^8
f(96) = 20×2^8
f(96) = 20×256
f(96) = 5,120
The number of bacteria that will be contained after 4days is 5,120bacterias
