Answer:
$8.27
Step-by-step explanation:
First we need to find the tip. We know it was 18% of the total. So...
x (the variable we need to find) 18%
__ = ___
10.08 (the total bill including tip) 100%
cross multiply
100x = 181.44
-------------------- (divide by 100 to get x by itself)
100
x = 1.81 (The 18% tip that was given)
So now we know how much the tip was, we subtract it from the bill
10.08 - 1.81 = $8.27
Answer:
Correct rate of change is -5; correct initial value is 3.
Step-by-step explanation:
The rate of change is the coefficient of the x term, which here is -5. So Bryan has the rate of change wrong.
The initial value of the function is found by letting x = 0. Here, we get
y = -5(0) + 3, or y = b = 3. The initial value is 3, not -5.
You find the square root of 576. The answer is 24
Answer:
Option A
Step-by-step explanation:
![\frac{12}{25} \times \frac{11}{24} \times \frac{10}{23} \times \frac{9}{22}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%7D%7B25%7D%20%20%5Ctimes%20%20%5Cfrac%7B11%7D%7B24%7D%20%20%5Ctimes%20%20%5Cfrac%7B10%7D%7B23%7D%20%5Ctimes%20%20%5Cfrac%7B9%7D%7B22%7D%20%20)
we start with 12 red marbles out of 25 marbles, that's the probability for the first.
in the second step we have one red marble less, wich also means one marble less overall
and so on
![\frac{12 \times 11 \times 10 \times 9}{25 \times 24 \times 23 \times 22}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%20%5Ctimes%2011%20%5Ctimes%2010%20%5Ctimes%209%7D%7B25%20%5Ctimes%2024%20%5Ctimes%2023%20%5Ctimes%2022%7D%20)
![= \frac{11880}{303600}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B11880%7D%7B303600%7D%20)
can be reduced by 1320 (step by step) to
![\frac{9}{230}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B230%7D%20)
