If 8/9 of a number is 328, find the number
Gre4nikov [31]

Answer: the number is 369

Step-by-step explanation:

Let the missing number be y

8/9 × y = 328

8/9y = 328

Divide both sides by 8/9

y = 328 ÷ 8/9

y = 328 × 9/8 (multiply the two numerators: 328 x 9= 2952

Multiply the denominator by 1: 8 x 1= 8

Therefore y = 2952/8

y = 369

I hope this helps.

The terminal arm of an angle drawn in standard position rotates in a positive direction through two quadrants of the coordinate
miskamm [114]
There are 4 quadrants and each quadrant is has a measure of 90° angle.

Because the direction is positive, it means that the arm is going from 1st quadrant to 2nd quadrant.

90° + 90° = 180°

Because there is an additional rotation of 25°, the arm is now in the 3rd quadrant. 

180° + 25° = 205°

The measure of the angle is 205°

A box, with rectangular sides, base and top is to have a volume of 2 cubic feet. It has a square base. Express the
Alex_Xolod [135]

The total surface area is 2w² + 8/w, while the total cost is $(20w² + 160/w)

<h3>What is volume?</h3>

Volume is the amount of space occupied by a three dimensional shape or object.

Let w represent the width of the base and h represent the height. Hence:

w²h = 2

h = 2/w²

The surface area = 2w² + 4(hw) = 2w² + 4(2/w² * w) = 2w² + 8/w

The total cost = 2w² * $10 + (8/w) * $20 = $(20w² + 160/w)

The total surface area is 2w² + 8/w, while the total cost is $(20w² + 160/w)
