<h3>Answer: 11/24</h3>

============================================================

Explanation:

Let's say we had 12 skateboards and 12 scooters. I'm picking 12 because 4*3 = 12 after multiplying the denominators. Doing this trick will mean we end up with whole number results instead of decimals.

If we had 12 skateboards, then (1/4)*12 = 3 of them are red. Having 12 scooters means (2/3)*12 = 8 scooters are red.

Add up the counts of each red item to get 3+8 = 11 red items out of 12+12 = 24 items total. Therefore, the answer is 11/24

Side note: The fraction 11/24 cannot be reduced because 11 and 24 have no factors in common other than 1.

Here are the graphs of L(x) and R(x) what are the values of L(2) and R(2)

Sedaia [141]

Using the function graph given, it is found that:

L(2) = 7.

R(2) = 1.

When a piece-wise function is given, that is, a function that has <em>multiple definitions</em>, the numeric value at x when the definition changes is given by the closed circle.

For function L(x), when x = 2, the closed circle is at y = 7, hence, L(2) = 7.

For function R(x), when x = 2, the closed circle is at y = 1, hence, R(2) = 1.

You know that your bill before tax is $52.60 and that sales tax rate is 8%. You decide to leave a 20% tip for the waiter. How mu

timofeeve [1]

Answer:

$10.52 tip should be given to the waiter.. The total bill including tax is $67.33

Step-by-step explanation:

We are given the following in the question:

Pre-tax amount = $52.60

Tip percentage = 20%

Tax percentage = 8$

Tip value =

$20\% \times 52.60\\\\=\dfrac{20}{100}\times 52.60\\\\=10.52\$$

Thus, $10.52 tip should be given to the waiter.

Tax value =

$8\% \times 52.60\\\\=\dfrac{8}{100}\times 52.60\\\\=4.21\$$

Total bill =

Pre tax amount + Tip + Tax

$=52.60 + 10.52 + 4.21\\=67.33$

Thus, the total bill including tax is $67.33

Estimate a 15% tip on a dinner bill of $61.53 by first rounding the bill amount to the nearest $10

adelina 88 [10]

well, 61.53 is really 10 + 10 + 10 + 10 + 10 + 10 + 1.53.

well, 1.53 doesn't really come nowhere near close to round up to 10, so it boils down to 0, so 61.53 will just be 10 + 10 + 10 + 10 + 10 + 10 + 0 or just 60 once rounded up, now, what's 15% of 60?

$\begin{array}{|c|ll} \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{15\% of 60}}{\left( \cfrac{15}{100} \right)60}\implies 9$

well, we can get the 15% of 61.53 by just (15/100) * 61.53

however, the exercise is asking on rounding it up to "tens" first

61.53 has "10" six times plus 1.53, the rounding happens with the "surplus"

in this case the surplus is 1.53.

now, for rounding anything the tipover point is at the half, for $10 the half is $5, so if the amount is $5 or more, rounds up to $10, if less than that goes to 0.

1.53 is nowhere near 5, which is the halfpoint or tipover point, because of that, it rounds up to 0, so 61.53 rounded up to "tens" only will be "six tens" only, or 60.
