Carolyn makes and sells necklaces. The material to make each neckalce costs $3.20. She has 12 necklaces to sell and wants to make a total profit of $54. The following equation describes the situation. 12 (x minus 3.20) = 54 Carolyn found that x = 7.7 and determined that she will make a profit of $7.70 on each necklace . Which error did Carolyn make? The solution means that she should charge $7.70 for each necklace. The solution means that each necklace costs $7.70 to make. The solution to the equation is not x = 7.7. Carolyn did not distribute the parentheses when solving.

Answer:

B. 2 gallons

Step-by-step explanation:

\(5\frac{1}{4} -1\frac{1}{4}\\=4-1\frac{1}{8}\\=2\frac{7}{8}\\2\frac{7}{8}-\frac{3}{4}=2\frac{1}{8}\sim2\)

Answer:

f(n) = 120 * (1/2)^n

Step-by-step explanation:

First the first number is 120, so we get y = 120, then 60/120 = 1/2

So we no the r, or constant rate is 1/2.

After that, we can finish our equation by doing

f(n) = 120 * (1/2)^n

or

y = 120*(1/2)^x

The explicit formula for the given geometric sequence is:

\(a_n = 120 \times 0.5^{n-1}\)

We have,

To find an explicit formula for the geometric sequence 120, 60, 30, 15, ...,

we need to determine the common ratio, denoted by 'r'.

To find the common ratio, we divide any term in the sequence by its preceding term.

Let's choose the second and first terms:

r = 60 / 120 = 0.5

Now that we have the common ratio 'r', we can express the nth term of the geometric sequence using the explicit formula:

\(a_n = a_1 r^{n-1}\)

where '\(a_n\)' represents the nth term of the sequence, '\(a_1\)' is the first term, 'r' is the common ratio, and 'n' is the position of the term we want to find.

Using the given sequence, '\(a_1\)' is 120, and 'r' is 0.5.

Plugging these values into the formula, we have:

\(a_n = 120 \times0.5^{n-1}\)

Therefore,

The explicit formula for the given geometric sequence is:

\(a_n = 120 \times 0.5^{n-1}\)

Answer: Rotate the point 180 degrees around the origin

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

Explanation:

Consider the point (2,3). Applying a dilation of scale factor -1 means we multiply each coordinate by -1. That moves us from (2,3) to (-2,-3). This rotates the point 180 degrees about the origin. It can be done clockwise or counterclockwise.

Extra Side Notes:

Answer:

101.25 km

Step-by-step explanation:

To solve, we need to first find how much she drives in one minute and then multiply that by the number of minutes she drives.

1.5 km = 2 minutes

divide both sides by 2.

1 minute = 0.75 km

2.25 hours = 2.25 * 60 =  135 minutes

Multiply the speed by the time to find distance.

135 * 0.75 = 101.25 km

Thus, she covered 101.25 km in 2 1/4 hours.

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Answer:

59.6 ft²

Step-by-step explanation:

The surface area of the pillow is the total area of the net.

The net is made up of 3 rectangles and 2 congruent triangles.

Area of a rectangle = width × length

Area of a triangle = 1/2 × base × height

Rectangle 1 (left)

area = 4 × 5 = 20 ft²

Rectangle 2 (middle)

area = 4 × 5.4 = 21.6 ft²

Rectangle 3 (right)

area = 2 × 4 = 8 ft²

Triangle

area = 1/2 × 5 × 2 = 5 ft²

(Be careful here, as it is easy to use the wrong length for the base of the triangle. The base and height of the triangle are perpendicular, so at right angles to each other.  Therefore, the base is 5ft and the height is 2ft)

Total area = rectangle 1 + rectangle 2 + rectangle 3 + 2 × triangle

                 = 20 + 21.6 + 8 + (2 × 5)

                 = 49.6 + 10

                 = 59.6 ft²
