Share 54 pounds in the ratio 5:4
ira [324]
In this item, we are asked to split the numerical value which is 54 pounds such that the ratio of the numbers will be 5:4. 
To answer, let 5x be the first number and 4x be the second number. With the given scenario, the equation that would best represent the given will be,                     
  54 = 5x + 4x
The value of x is 6 giving us the values of 5x and 4x as 30 and 24, respectively. 

Hence, the split will be 30 and 24.

a local high schools cheerleading squad is selling snow cones during lunch to raise money for a national cheerleading competitio
svlad2 [7]
We have:

Volume of cone = 535 cm³ at the maximum
Height of cone= 8cm

We know the formula to find volume of cone is \frac{1}{3} r^{2}  \pi h

We need to find the radius of the base of the cone
535= \frac{\pi  r^{2}8} {3}
535*8= \pi  r^{2}
\frac{4280}{\pi}= r^{2}
r= \sqrt{ \frac{4280}{ \pi}   }
r=36.9 to the nearest one decimal place

The width of the opening of the cone is the diameter of the circle. Diameter is twice the radius, hence 2×36.9=73.8 cm
