You need school supplies. You go to the store and see that there are 6 different backpacks, 8 notebooks, 3 packets of pens, and

8 folders to choose from. You decide to go to another store to see their selection. The second store had a third of the backpacks, half the notebooks, and triple the number of pens. How many folders would the new store need to have in order for there to be the same number of combinations of items to choose from in the second store than in the first store?

<span>In a 30-60-90  triangle the side opposite the 30 degree angle is half the length of the hypotenuse. 
The short leg is </span>the side opposite the 30 degree angle. If the short leg =x, then the hypotenuse = 2x

The ratio of the short leg to the hypotenuse in the given triangle is cos(60°)

&#10;cos(60^o) = \frac{adjacent \ side}{hypotenuse  } =  \frac{x}{2x} = \frac{1}{2}

(03.01 LC) Given that h(x) = 3x −19, find the value of x that makes h(x) = 71. (5 points)
LekaFEV [45]
The function given is:
h(x) = 3x-19
we want to find the value of x that makes this function equal to 71. To do so, we will substitute h(x) with 71 and solve for x as follows:
h(x) = 3x - 19
71 = 3x - 19
3x = 71+19
3x = 90
x = 90/3 = 30
