An artist is selling children's crafts. Necklaces cost $2.25 each, and bracelets cost $1.50 per each.
Select all the combinations of necklaces and bracelets that the artist could sell for exactly $12.00.
A:
5 necklaces and 1 bracelet
B:
2 necklaces and 5 bracelets
C:
3 necklaces and 3 bracelet
D:
4 necklaces and 2 bracelets
E:
3 necklaces and 5 bracelets
F:
6 necklaces and no bracelets
G:
No necklaces and 8 bracelets
Answer:
The combinations of necklaces and bracelets that the artist could sell for exactly $12.00 are
B: 2 necklaces and 5 bracelets
D: 4 necklaces and 2 bracelets
G: No necklaces and 8 bracelets
Step-by-step explanation:
let the number of necklace be x
the number of bracelets be y
Then
The cost of one necklace is $2.25
The cost of one bracelets is $1.50
Thus
x(2.25) + y(1.50) = 12.00-------------------------(1)
Option A : 5 necklaces and 1 bracelet
(5)(2.25) + (1)(1.50) = 12.00
11.25 + 1.50 = 12.00
12.75 > 12.00
Option B :2 necklaces and 5 bracelets
(2)(2.25) + (5)(1.50) = 12.00
4.5 + 7.5 = 12.00
12. 00 = 12.00
Option C: 3 necklaces and 3 bracelets
(3)(2.25) + (3)(1.50) = 12.00
6.75 + 4.50 = 12.00
11.25 < 12.00
Option D: 4 necklaces and 2 bracelets
(4)(2.25) + (2)(1.50) = 12.00
9.00 + 3.00 = 12.00
12.00 = 12.00
Option E: 3 necklaces and 5 bracelets
(3)(2.25) + (5)(1.50) = 12.00
6.75 + 7.5 = 12.00
14.25 > 12.00
Option F: 6 necklaces and no bracelets
(6)(2.25) + (0)(1.50) = 12.00
13.5 + 0 = 12.00
13.5 > 12.00
Option G: No necklaces and 8 bracelets
(0)(2.25) + (0)(1.50) = 12.00
0 +12.00= 12.00
12.00 = 12.00
The combinations of necklaces and bracelets that the artist could sell for exactly $12.00.
B: 2 necklaces and 5 bracelets
D: 4 necklaces and 2 bracelets
G: No necklaces and 8 bracelets
Since the artist is selling necklaces at $2.25 each, and bracelets at $1.50 per each, then the corresponding values will be:
2(2.25) + 5(1.50) = 4.50 + 7.50 = 12.00
4(2.25) + 2(1.50) = 9 + 3 = 12.00
0(2.25) + 8(1.50) = 0 + 12 = 12
In conclusion, the correct options are B, D, and G.

OD. The student should have used

Answer:
B. On Pearson (-1/4) D on Egdenuity(-1/4)
The student erred in calculating the slope for the line perpendicular to the given line. They should have used -1/4 instead of 2. The correct equation is y - 5 = -1/4 * (x + 8).
Explanation:The error the student made lies in calculating the slope of the line that is perpendicular to given line y = 4x + 2. The slope of this line is 4, therefore the slope of the line perpendicular to it should be the negative reciprocal of 4, which is -1/4, not 2 as the student assumed. We also use the point-slope form of the line which is y - y1 = m(x - x1). Substituting m as -1/4 (the slope of perpendicular line) and the point (-8,5) into the equation, we should get y - 5 = -1/4 * (x + 8).

I need to know whether or not 15, 13, 11, 9, ... is an arithmetic sequence
Answer: Yes
Step-by-step explanation: An arithmetic sequence is a sequence that has a common difference. The common difference is the number that is repeatedly added or subtracted to reach the next term in the sequence.
In this sequence, notice that we start with 15. Then, we subtract 2 to reach our next term which is 13. Next, we subtract 2 to get to our next term which is 11. In the same way, we subtract 2 from 11 to reach our next term, 9.
The dot dot dots just mean that this sequence goes on forever so to answer your question, this is indeed an arithmetic sequence.

What’s the x-intercepts, vertex, y-intercept? y=(x+1)2-16
The vertex is (-1, -16)
x intercepts is : (3, 0) or (-5, 0)
y intercept is (0, -15)
Solution:
Given is:
[tex]y = (x+1)^2 - 16[/tex]
The vertex form of an equation is given as:
[tex]y = a(x-h)^2 + k[/tex]
Where, (h, k) is the vertex
On comparing the above equation with given,
h = -1
k = -16
Thus the vertex is (-1, -16)
Find the x intercept:To find the x-intercept, substitute y = 0 in given
[tex]0 = (x + 1)^2 - 16\\\\x^2 + 2x + 1 - 16 = 0\\\\x^2 + 2x - 15 = 0\\\\Split\ the\ middle\ term\\\\x^2 - 3x +5x - 15 = 0\\\\(x^2 -3x) + (5x - 15) = 0\\\\x(x - 3) + 5(x - 3) = 0\\\\Factor\ out\ x - 3\\\\(x-3)(x + 5) = 0\\\\x = 3\\\\x = -5[/tex]
Thus x intercepts is : (3, 0) or (-5, 0)
Find the y intercept:To find the y-intercept, substitute x = 0 in given
[tex]y = (0+1)^2 - 16\\\\y = 1 - 16\\\\y = -15[/tex]
Thus the y intercept is (0, -15)

Are the polygons similar? If they are, choose the correct similarity statement and scale factor. Not drawn to scale.
Option B: [tex]$\Delta R S T \sim \Delta UV W ; \frac{5}{6}$[/tex]
Explanation:
The polygons are similar because in [tex]$\Delta R S T$[/tex], the measure of ∠R=32°
Also, in [tex]$\Delta U V W$[/tex], the measure of ∠U=32°
Now, we shall find the scale factor,
Since, [tex]$\Delta R S T \sim \Delta U V W$[/tex], then the sides are proportional which is given by,
[tex]\frac{RS}{UV}[/tex]
Substituting the values of RS and UV from the figure, we get,
[tex]\frac{10}{12}[/tex]
Simplifying, we have,
[tex]$\frac{5}{6}$[/tex]
Thus, the scale factor is [tex]$\frac{5}{6}$[/tex]
Hence, Option B is the correct answer.
A rectangle flag had a width of 3 2\3 feet and area of 8 3/4 square feet . Which expression could be used to calculate the length , in feet , of the rectangle
Pretty sure it's 8 3/4 ÷ 3 2/3.
Why?
So say you want to find the length of a rectangle who's area is 6, and the width is 2. You can divide the area by the width to find the length. 6/2 = 3.
Check: 2 * 3 = 6.
Back to the original question: 8 3/4 ÷ 3 2/3.
Improper fractions: 35/4 ÷ 11/3.
Switch division to multiplication and reciprocal: 35/4 * 3/11.
35/4 * 3/11 = 105/44.
Check:
105/44 * 11/3 = 1155/132 = 35/4 = 8 3/4
Length = 105/44
Final answer:
To find the length of the rectangle, we use the formula Area = length imes width, converting the given mixed numbers into improper fractions, and then dividing the area by the width.
Explanation:
To calculate the length of the rectangle given the width and the area, we can use the formula for the area of a rectangle: Area = length times width. To isolate the length, we divide both sides of the equation by the width. Given that the width of the rectangle is 3 2/3 feet and the area is 8 3/4 square feet, the expression to find the length is:
Length = Area / Width
First, we convert the mixed numbers into improper fractions:
Width: 3 2/3 = 11/3 feet
Area: 8 3/4 = 35/4 square feet
Then, the calculation for the length is:
Length = (35/4) / (11/3) feet

The population of growth of a town is 20,000 it decreased at a rate of 9% per year in about how many years will the population be fewer than 13,000
Answer:
4 years
Step-by-step explanation:
9% of the population is 1800. subtract that to get 18200. thats 1 year. subtract again to get 16400. thats 2 years. again to get 14600. 3 years. and then again to get 12800 which is less than 13000. so its 4 years.
Final answer:
Using the exponential decay formula, it takes approximately 8 years for a town's population of 20,000 to decrease to fewer than 13,000 at a yearly decrease rate of 9%.
Explanation:
The question involves calculating the number of years it takes for a town's population to decrease to fewer than 13,000 given an initial population of 20,000 and a yearly decrease rate of 9%. To solve this, we use the formula for exponential decay, which is P(t) = P₀[tex]e^{rt}[/tex], where P(t) is the population at time t, P0 is the initial population, r is the rate of decrease, and t is the time in years.
Substituting the given values, we have 13,000 = 20,000[tex]e^{-0.09t}[/tex]. Solving for t, we take natural logarithms on both sides, which gives ln(13,000/20,000) = -0.09t, leading to t = ln(13,000/20,000) / -0.09. This calculation yields t ≈ 8.04 years, meaning the population will be fewer than 13,000 in about 8 years.
This is a practical application of exponential decay in analyzing population dynamics, highlighting how populations decrease over time under consistent negative growth rates.

A classroom can accommodate less than 21 students.
Which of the following inequalities represents the number of students the classroom can accommodate?
Answer:
x<21
Step-by-step explanation:
How I always do it is I write down the number that was in the problem. So write down 21. Next I write down less. Then, if it says less, then the inequality sign's open side will face the number. This will be the opposite if the problem says more
The inequality representing a classroom that can accommodate fewer than 21 students is s < 21, which means the classroom can hold any number of students from 1 up to 20.
Explanation:The question asks which inequality represents the number of students a classroom can accommodate if it can hold fewer than 21 students. To express this mathematically, we use an inequality sign. Since the classroom can accommodate less than 21 students, it means the number of students (let's call this number s) must be strictly less than 21. Therefore, the inequality that correctly represents this condition is s < 21.
This inequality means that any whole number of students from 1 up to 20 can fit in the classroom, as all these values are less than 21. It's crucial to understand that the inequality does not include 21 itself, because it specifies "less than," not "less than or equal to."
