Answer:
Density = 52.8 pound per cubic feet.
Step-by-step explanation:
Given the following data;
Length = 2.5 feet
Width = 0.5 feet
Height = 0.25 feet
Mass = 16.5 pound
To find the density of the wood;
First of all, we would determine the volume of the wood.
Volume = length * width * height
Volume = 2.5 * 0.5 * 0.25
Volume = 0.3125 cubic feet
Next, we find the density;
Mathematically, density is given by the formula;
Density = mass/volume
Substituting into the formula, we have;
Density = 16.5/0.3125
Density = 52.8 pound per cubic feet.
Answer:
Step-by-step explanation:
<u>Equation for this case is:</u>
⇒ y = 6(x - 1) + 10 as Rs. 10 for the first km and Rs. 6 for the rest (x - 1) km
⇒ y = 6x - 6 + 10 simplifying
⇒ y = 6x + 4 final equation
<u>For x = 15 km we have total of:</u>
Answer:
$10.25
Step-by-step explanation:
20.50 / 2
<span>A
grade has 81 girls and 72 boys. The greatest split into groups that have the
same ratio girls the boys as a whole grade.
=> Find how many girls are in a group that has 16 boys
Formula and Ratio:
=> 81 : 72 = x : 16 – we need to find the value of girls or the number of
girls in the given ratio.
=> 16 * 81 = 1 296
=> 1 296 / 72 = 18
Therefore the value of girls numbers is 18. The new ratio will be:
18 : 16
