Kyle bought himself a pair of shoes for 89.50 and he bought his nephew a pair for half the price of his shoes. If the sales tax
ycow [4]
Solution-

89.50/2 = 44.75

44.75 is the amount he spent to buy his nephew the pair of shoes.

Now, we are going to add the amount he spent for himself and his nephew together. 

89.50 + 44.75= 134.25

134.25 is the amount he spent in total, now we need to find the final amount with sales tax included.

We can do this by multiplying the total price by .075

134.25 * .075 = 10.07 (I rounded this to the nearest hundredths because we are dealing with money)

Now we need to add the two number together. 

134.25 + 10.07 = 144.32

Answer- 

The total amount Kyle spent is $144.32

Which are the solutions of the quadratic equation?
Artemon [7]

Answer:

x_1=\frac{7+\sqrt{65}} {2}

x_2=\frac{7-\sqrt{65}} {2}

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^{2}=7x+4  

equate to zero

x^{2}-7x-4=0  

so

a=1\\b=-7\\c=-4

substitute in the formula

x=\frac{-(-7)\pm\sqrt{-7^{2}-4(1)(-4)}} {2(1)}

x=\frac{7\pm\sqrt{65}} {2}

therefore

x_1=\frac{7+\sqrt{65}} {2}

x_2=\frac{7-\sqrt{65}} {2}

StartFraction 7 minus StartRoot 65 EndRoot Over 2 EndFraction comma StartFraction 7 + StartRoot 65 EndRoot Over 2 EndFraction
