A bag of corn tortilla chips costs 2.89 after a 15% discount. What is the original price?
Montano1993 [528]

Answer:

3.4

Step-by-step explanation:

Let the original price of the bag be = P, the selling price =2.89 after a 15% discount,

Then, Selling price= Original price- Discount on original price

2.89=P-P(0.15)

2.89=P(1-0.15)

2.89=0.85P

P=\frac{2.89}{0.85}

P=3.4

Thus, the original price was 3.4.

Write the ratio of the area of a circle with radius r to the circumference of the same circle
Goshia [24]

Answer:

\frac{r}{2\pi r} =\frac{1}{2\pi }

Step-by-step explanation:

A ratio is a comparison of two quantities and can be written in several forms including fractions. It is most commonly written in fraction form or a:b.

To write a ratio, we count the number of each quantity we are comparing or use the variable for that quantity. We write radius:circumference. Recall, the circumference of a circle can be found using \pi d or 2\pi r.

We write r: \pi d  or r:2\pi r.

We can also write in fraction form:

\frac{r}{\pi d} or \frac{r}{2\pi r} =\frac{1}{2\pi }

X is less than or equal to 2 Write in interval notation.
Talja [164]
X is less than -2, so -2 is our largest value of the interval, so it goes on the right. Since there is no lower endpoint (it is ALL values less than -2), we put the negative infinity symbol on the left side. The curved end on -2 indicates an open interval

From the table:
x1 = 0.357
x2 = 0.372
x3 = 0.350
x4 = 0.349
x = ?

<u>0.357 + 0.372 + 0.350 + 0.349 + x = 1.754</u>

1.428 + x = 1.754
x = 1.754 - 1.428
<u>x = 0.326</u></span>
