Answer:
D
Step-by-step explanation:
The additive inverse is what you add to a number to get zero.
Given
- 10 [tex]\frac{1}{4}[/tex], then the additive inverse is
10 [tex]\frac{1}{4}[/tex]
since
- 10 [tex]\frac{1}{4}[/tex] + 10 [tex]\frac{1}{4}[/tex] = 0

If tax was 8.25% on the $220 total for the items purchased at Target, what was the total cost of the items including tax?
Answer:
$238.15
Step-by-step explanation:
8.25% = 8.25/100 or 0.0825
Multiply 0.0825 and 220 to get $18.15. That's how much the tax is.
Add 220 and 18.15 to get $238.15
Answer:
$238.15
Step-by-step explanation:
To find the total cost of the items including tax you will need to multiply the cost of the items by the decimal form of 8.25%.
The decimal form of 8.25% is .0825. When turning percents to the decimal form we move the decimal two places to the left.
Now we multiply!
(220)(.0825) = 18.15
Now add 18.15 onto the 220 to find the total cost including tax:
220 + 18.15 = 238.15
Therefore, the total cost of the items including tax is $238.15.
I hope this helps!!

3. Back in elementary school, I learned a great magic trick to compare two positive fractions. Here’s
my magic trick in action. Consider the fractions 5
19 and 6
23 . I multiply the numerator of the first and
the denominator of the second, and get 5 · 23 = 115. I multiply the numerator of the second and the
denominator of the first, and get 6 · 19 = 114. Because 115 > 114, I know that 5

Why does this magic trick work? In other words, if a, b, c, and d are positive, then why does ad > bc
mean that a

What composition forms the equation p(x) when given the functions for h(x), f(x), k(x), and g(x)? PLEASE HELP!!!!! thank you!!!!! *will ofc give brainliest*
Answer: Choice B. k(h(g(f(x))))
For choice B, the functions are k, h, g, f going from left to right.
===========================================================
Explanation:
We have 4x involved, so we'll need f(x)
This 4x term is inside a cubic, so we'll need g(x) as well.
So far we have
g(x) = x^3
g( f(x) ) = ( f(x) )^3
g( f(x) ) = ( 4x )^3
Then note how we are dividing that result by 2. That's the same as applying the h(x) function
[tex]h(x) = \frac{x}{2}\\\\h(g(f(x))) = \frac{g(f(x))}{2}\\\\h(g(f(x))) = \frac{(4x)^3}{2}\\\\[/tex]
And finally, we subtract 1 from this, but that's the same as using k(x)
[tex]k(x) = x-1\\\\k(h(g(f(x)))) = h(g(f(x)))-1\\\\k(h(g(f(x)))) = \frac{(4x)^3}{2}-1\\\\[/tex]
This leads to the answer choice B.
To be honest, this notation is a mess considering how many function compositions are going on. It's very easy to get lost. I recommend carefully stepping through the problem and building it up in the way I've done above, or in a similar fashion. The idea is to start from the inside and work your way out. Keep in mind that PEMDAS plays a role.
