Acompany that manufactures storage bins for grains made a drawing of a silo. the silo has a conical base, as shown below: the figure shows a silo shaped as a closed cylinder with a conical end. the diameter of the silo is 4 ft, the length of the cylindrical part is 8.5 ft, and the entire length of the silo is 13 ft. which of the following could be used to calculate the total volume of grains that can be stored in the silo? π(8.5ft)2(2ft) + one over threeπ(2ft)2(13ft − 8.5ft) π(2ft)2(8.5ft) + one over threeπ(2ft)2(13ft − 8.5ft) π(8.5ft)2(2ft) + one over threeπ(13ft − 8.5ft)2(2ft) π(2ft)2(8.5ft) + one over threeπ(13ft − 8.5ft)2(2ft)

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
