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

Select the correct answer. If the zeros of a quadratic function are 3 and 8, what are the factors of the function? A. (x + 8) an
almond37 [142]

Answer:

C. (x-8) and (x-3)

Step-by-step explanation:

When we calculate the zeros of a function, we are calculating the points where that function crosses the x axis, and to do so we have to equal the function to zero and isolate X.

(x - 3) . (x-8) = 0

The only way a multiplication can have a result of 0, is that any of it's factors were equal to zero. So we can take both factors and equal them to zero and isolate x to know the function's zeros.

(x - 3) = 0\\x = 3

(x-8) = 0\\x = 8

cestrela7 [59]
You can change mm into cm.  Since 1 cm is equal to 100 mm, divide 500 by 100 to get 5 cm.  Add 30 and 5 to get 35.  The two line segments are 35 cm together.
