One number is 4 times the other, so x and 4x.
The sum of two numbers is 4x+x=70.
Solve for x to get
x=70/5=14
the other number is 4x=4*14=56
Took 3 of us in grade 10 but johns present age is 77.5 and his sister is 72.5
To answer this item, we assume that the topic is in similar polygons such that the ratio of the corresponding sides should be equal. In this item,
BY/YC = AX/XC
Substituting the known values,
6/10 = 18/XC
The value of XC from the equation is 30. The answer is letter C.
The length of one side of the square base is 8.5 centimeters.
<u>Given the following data:</u>
- Volume of cuboid = 867 cm
To find the length of one side of the square base:
Mathematically, the volume of a cuboid is given by the formula:
× 
Substituting the given values, we have:
× 

Base area = 72.225 
Now, we can find the length by using the formula:



<em>Length</em><em> = </em><em>8.5 centimeters</em>.
Therefore, the length of one side of the square base is 8.5 centimeters.
