Answer:
The radius of the can is 7.28 cm .
Step-by-step explanation:
By our general knowledge, a "can" is a cylinder. It is given that the volume of can is 2500 cm³ and the height is 15 cm tall so we have to use the formula of volume of cylinder to find the radius :
Let r be radius, v be volume and h be height,
Let v = 2500 cm³,
Let h = 15 cm,
If we're going to use an inequality to solve this, then we'd probably be saying that 3.25 x ? >210. The 3.25 is the selling price per taco and the ? is the number of tacos that you sell. According to the equation, the number of tacos times the selling price has to be greater than 210, which are the expenses, in order to gain a profit. If we solve this, we simply divide 210 by 3.25. We will get an answer of 65. So we can conclude that if the taco business wants to have a profit, then they have to sell more than 65 tacos so that they can be able to cover their expenses.
Answer:
B
Step-by-step explanation:
The slope of a line is written as a fraction of the vertical distance to the horizontal distance. The line drops down from (0,1) to (4,-2). This is a vertical distance of -3 and a horizontal distance of 4. The slope is the fraction -3/4.
