Answer:
It will equally 2 because you need to change the 3 into a 9 because you can't add fractions without having the same common demometer
Step-by-step explanation:
1. You have that:
- Each gallon of paint covers 400 ft²<span>.
- One side of a wall must be painted and its dimensions are :is 8 meters tall and 40 meters long.
1 ft=0.3048 m
1 ft</span>²=(0.3048 m)²=0.09290 m²
2. Each gallon of paint covers 400 ft<span>², then:
</span>
400 ft²x<span>0.09290=37.16 m</span>²
3. The area of one side of the wall is:
A=8 mx40 m
A=320 m²
4. Therefore, you have:
1 gallon-----37.16 m²
x-----320 m²
x=320x1/37.16
x=8.61 gallons
x≈9 gallons
The answer is: 9 gallons

Answer:</h2>
<h2>
Step-by-step explanation:</h2>
A prism is a solid object having two identical bases, hence the same cross section along the length. Prism are called after the name of their base. On the other hand, a rectangular prism is a solid whose base is a rectangle. Multiplying the three dimensions of a rectangular prism: length, width and height, gives us the volume of a prism:
From the statement of the problem we know:
So:
Since we can't have negative distance, the only valid option is
Answer:
C ) 10/m⁵
Step-by-step explanation:
In this question, we have to find the product of two terms
First term = 5 m⁻²
Second term = 2 m⁻³
Product of both terms = (5 m⁻²) · (2 m⁻³)
The simple way of calculating product of these two term which involves constants as well as variable is that we multiply the constants together:
5·2 = 10
And we multiply the variables. According to the rules of multiplication, when 2 same constants or variables are multiplied, we can just add their powers to get the result.
(m⁻²) · (m⁻³) = m⁻²⁻³ = m⁻⁵
The product of both terms can be written as:
(product of constants)(product of variables) = (10)(m⁻⁵) = 10/m⁵
So the correct option is C
