There are 12 bags in a box of popcorn that cost $8.25. Find the unit rate for ONE bag of popcorn. Round to the hundredths place.

goldfiish [28.3K]

Answer:

$0.69 for each bag

Step-by-step explanation:

Since you have 12 bags for $8.25, that means you need to divide the price by the number of bags to get the price of each:

$\frac{8.25}{12} = 0.6875$

You then need to round to the nearest hundredths. Since the number after the hundredths place is a 7, which is greater than or equal to 5, you need to add 1 to the hundredths place making the final answer $0.69

Answer:

a. The total length of cloth that the dressmaker bought.

b. 2/5 m, 1/3 m, 1/6 m

c. Addition of fractions

Step-by-step explanation:

Step 1. Get the LCD or least common denominator which is in this case 30.

Step 2. Transform each fraction into similar fractions having the same denominator.

12/30, 10/30, 5/30

Step 3. Add now the similar fractions and simplify to lowest terms

27/30 ÷3 = 9/10

Write the equation of the line that passes through the points (8,−7) and (−9,7). Put your answer in fully reduced point-slope fo

Sunny_sXe [5.5K]

Answer:

y + 7 = (-14/17)(x - 8)

Step-by-step explanation:

We want the equation of this line in the point-slope form y - k = m(x - h).

We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above. Then the other point is represented by (x, y) in the point slope form shown above:

Let (h, k) be 8, -7) and let (x, y) be (-9, 7). Then, y - k = m(x - h) becomes:

7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17

The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).

Another way to get this result would be to find m in the usual way:

rise 14

m = ------------- = --------- = -14/17 (same as before).

run -17
