Depending on which number you choose, you will have the same chance for each of them. To find out the chance of each of them, you first need to find the denominator, which is 6 because there are 6 sides of a dice. Now, we need to find the numerator. How many sides are we looking at? 1? 2? 3? Depending on how many sides there are, is your probability. So, if there is one side you are trying to find, it would be 1/6. If there are two sides, it would be 2/6 or 1/3. And so on.

a television normally sells for $499 what is now discounted 25%. The sales tax rate is 6.5%. What is the total cost of televisio

matrenka [14]

Hmmm what is now discounted? well, let's assume it sells normally for 499 and is discounted today at 25%, how much is that?

well, if we take 499 to be the 100, how much is 25%?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
499&100\\
d&25
\end{array}\implies \cfrac{499}{d}=\cfrac{100}{25} \cfrac{499\cdot 25}{100}=d
\\\\\\
124.75=d\qquad \textit{so the new price is }499-124.75\implies 374.25$

now, applying the sales tax to the discounted price.

if we take 374.25 to be the 100%, how much is 6.5%?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
374.25&100\\ t&6.5
\end{array}\implies \cfrac{374.25}{t}=\cfrac{100}{6.5}\implies \cfrac{374.25\cdot 6.5}{100}=t$

so, the total cost will then be 374.25 + t.

How do I find the sum and Express it in simplest form ? (3t^2+6t)+(-9t^2-5t+5)

Leona [35]

-6t²+t+6

1. Let's group terms like, after eliminating the parentheses.

(3t²+6t+1)+(-9t²-5t+5)

3t²+6t+1-9t²-5t+5

3t²-9t² +6t-5t +5+1

-6t²+t+6

This is the simplest and most convenient form since there' s already a coefficient 1 in term "t".

Answer:

Step-by-step explanation:

They tell you the answer in the picture. Angle DAB is the lower left vertex, so its measure is 80°

Angle BCD is the upper right vertex.
