Answer:
Volume = 1.9 in3
Step-by-step explanation:
If the perimeter of the square base is 5 inches, we have that:
Perimeter = 4 * side
5 = 4 * side
side = 1.25 in
Then, to find the volume of the pyramid, we can use the formula:
Volume = (1/3) * side^2 * height
So we have that:
Volume = (1/3) * 1.25^2 * 3.6
Volume = 1.875 in3
Rounding to nearest tenth, we have Volume = 1.9 in3
Answer:
3
Step-by-step explanation:
The unit rate for three dollars for 2 1/2 hours of work will be $1.2 using the concept of unitary method.
<h3>What is unitary method?</h3>
The unitary method is a technique that involves determining the value of a single unit and then calculating the value of the requisite number of units based on that value. The term unitary refers to a single or unique entity. As a result, the goal of this approach is to determine values in reference to a single unit. The unitary technique is a method for determining the value of any necessary quantity by first obtaining the value of the unit (one) quantity.
Here,
$3 for 2.5 hours of work,
1 hour will cost $x,
3/2.5=x/1
2.5x=3
x=$1.2
Using the unitary technique, the unit rate for three dollars for two and a half hours of labour will be $1.2.
