Answer:

He needs 31.25 bales of hay to feed 15 horses for two weeks

Step-by-step explanation:

This question can be solved using a rule of three.

25 bales of hay feed 12 horses. How many feed 15 horses?

12 horses - 25 bales of hay

15 horses - x bales of hay

12x = 25*15

x = \frac{25*15}{12}

x = 31.25

He needs 31.25 bales of hay to feed 15 horses for two weeks

Sam is ordering shirts online. The shipping is a flat rate of $5.99, and each shirts costs $12.50. He spent $80.99 in total. How
ANEK [815]

Based on the shipping rate and the price of the t-shirts, it can be concluded Sam ordered a total of 6 t-shirts.

<h3>What equation represents Sam's situation?</h3>

5.99 + x12.50 = 80.99

x represents the number of t-shirts she bough, which is the focus of the equation.

Let's solve it:

  • 5.99 + x12.50 = 80.99
  • x12.50 = 80.99 - 5.99
  • x12.50 = 75
  • x = 75 / 12.50
  • x = 6

<h3>How many t-shirts did Sam order?</h3>

Sam ordered 6 t-shirts.

Y = (x²+3)(2x-6)<br> What is the derivative?
ahrayia [7]

Answer:

y = (x²+3)(2x-6)

  • dy/dx=d(x²+3)(2x-6)/dt=(x²+3)d(2x-6)/dt+(2x-6)d(x²+3)/dt= (x²+3)(2)+(2x-6)(2x)=2x²+6+4x²-12x=6x²-12x+6=6(x²-2x+1)
