Okay, so:
You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.
So,
423*.1
(you have to turn the percentage into a decimal; 10%= .10
423*.1= 42.3
So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.
I hope this helps!

Answer: 10x+16
Step-by-step explanation:
Use the distributive property a(b+c)= ab+ac
so
-2(-5x-8) = (-2 * -5x) - (-2* -8)
=
10x-(-16)
=10x+16
Hope this helped!
Answer:
C) Tom did not distribute to both terms in parentheses.
Step-by-step explanation:
Addition within a paranthesis has a distributive property to the multiplier outside the paranthesis. Ignoring this will lead to a wrong value for the operation.
We're looking for the two values being subtracted here. One of these values is easy to find:
<span>g(1) = ∫f(t)dt = 0</span><span>
since taking the integral over an interval of length 0 is 0.
The other value we find by taking a Left Riemann Sum, which means that we divide the interval [1,15] into the intervals listed above and find the area of rectangles over those regions:
</span><span>Each integral breaks down like so:
(3-1)*f(1)=4
(6-3)*f(3)=9
(10-6)*f(6)=16
(15-10)*f(10)=10.
So, the sum of all these integrals is 39, which means g(15)=39.
Then, g(15)-g(1)=39-0=39.

I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
Option A
Step-by-step explanation:
Bag A: 30 cents per bag
Bag B: 31 cents per bag
In order to find Cents per bag divide the number of bags from the amount it costs.
Bag A: 6 ÷ 20 = 0.30
Bag B: 9.92 ÷ 32 = 0.31
