Aliyah has 75 candy canes and 45 holiday cookies. She wants to divide them into gift bags, so that each bag has an equal number of candy canes and each bag has the same number of cookies as all the other bags. What is the greatest number of gift bags that Aliyah can make? How many candy canes will be in each bag? How many cookies will be in each bag?
Answer:
1) 15 gift bags2) 3 holiday cookiesExplanation:
1) Find the greatest number that divides exactly both 75 (candy canes) and 45 (holiday cookies).
That is, find the GCF (greatest common factor) of 75 and 45.
45 = 3² × 575 = 3 × 5²GCF = common factors each raised to its least exponent: 3×5 = 15Then, the greatest number of gift bags, so that each bag has an equal number of candy canes and same number of cookies that Aliyah can make is 15.
2) How many cookies will be in each bag?
To find the number of cookies that will be in each bag, you divide the number of holiday cookies by the number of gift bags:
45 holiday cookies / 15 gift bags = 3 holiday cookies per bag.Thus, each bag will contain 3 holiday cookies.

A concrete patio is
[tex]5 \frac{2}{3} [/tex]
feet wide. It has an area of
[tex]36 \frac{2}{3} [/tex]
square feet. is the concrete slab long enough to fit a 7-foot picnic table without placing the table along the diagonal of the patio? Explain.
The length of concrete patio is 6.5 feet which is less than given 7 foot picnic table. So the concrete slab is not enough to fit a 7 foot picnic table
Solution:
Given that concrete patio is [tex]5\frac{2}{3}[/tex] feet wide
Area of concrete patio = [tex]36\frac{2}{3}[/tex] square feet
Therefore,
[tex]\texttt{Width of concrete patio = }5\frac{2}{3}=\frac{5\times 3+2}{3}=\frac{17}{3}feet\\\\\text{Area of concrete patio = }36\frac{2}{3}=\frac{36\times 3+2}{3}=\frac{110}{3}feet^2[/tex]
Let us find the length of concrete patio
Concrete patio is usually of shape rectangle
Area of concrete patio = length x width
[tex]\frac{110}{3} = length \times \frac{17}{3}\\\\length = \frac{110}{3} \times \frac{3}{17}\\\\length = \frac{110}{17} = 6.4705 \approx 6.5[/tex]
Therefore length of concrete patio is 6.5 feet
So it cannot fit the 7 foot picnic table. Since the length of concrete patio is 6.5 feet which is less than given 7 foot picnic table

Two trains leave Stations 396 miles apart at the same time and travel towards each other. One train travels at 95 mph while other travels 85 mph. How long will it take two trains to meet?
It will take 2.2 hours for the trains to meet.
Step-by-step explanation:
Given,
Distance between two trains = 396 miles
Speed of one train = 95 mph
Speed of other train = 85 mph
Combined speed of trains = 95+85 = 180 mph
Distance = Speed * Time
Time = [tex]\frac{Distance}{Speed}[/tex]
Time = [tex]\frac{396}{180}[/tex]
Time = 2.2 hours
It will take 2.2 hours for the trains to meet.

The two trains will take approximately 2.2 hours to meet.
Explanation:To find the time it takes for the two trains to meet, we can use the formula:
Time = Distance/Speed
In this case, the distance between the two trains is 396 miles. The combined speed of the two trains is 95 mph + 85 mph = 180 mph. Substituting these values into the formula, we get:
Time = 396/180 = 2.2 (rounded to the nearest tenth)
So it will take approximately "2.2 hours" for the two trains to meet.

Use the equation below to answer the question.
y = 3x + 6
Which equivalent equation is correctly matched with a key feature of the graph of the function it represents?
Answer:
The signa notation to represent the first five ten f(x) is given by [tex] f(x)=\sum\limits^{5}_{n=1}a_n[/tex]
Step-by-step explanation:
Given sequence is -5, -9, 13...
Let f(x) be the given sequence and is denoted by
[tex]f(x)=\{-5,-9,-13,...\}[/tex]
Let the first term be [tex]a_1, 2^{\textrm{nd}}[/tex] term be [tex]a_3,...[/tex]
ie, [tex]a_1=-5,a_2=-9, a_3=-13,...[/tex]
To find the common difference d:
[tex]d=a_2-a_1[/tex]
[tex]=-9-(-5)[/tex]
[tex]=-9-(+5)[/tex]
[tex]d=-4[/tex]
[tex]d=a_3-a_2[/tex]
[tex]=-13-(-9)[/tex]
[tex]=-13+9[/tex]
[tex]d=-4[/tex]
Therefore the common difference d is -4 for given sequence f(x) with [tex]a_1=-5[/tex] and d=-4, the seqence f(x) is an arithmetic sequence
By defintion of arithmetic sequence
[tex]a_n=a+(n-1)d\hfill(1)[/tex]
Now to find [tex]a_4, a_5[/tex]:
put n=4 in equation (1)
[tex]a_4=a+(4-1)d[/tex]
[tex]a_4=-5+(3)(-4)[/tex] [since a=-5, d=-4]
[tex]=-5-12[/tex]
[tex]a_4=-17[/tex]
in equation (1)
[tex]a_5=a+(5-1)d[/tex]
[tex]a_5=-5+(4)(-4)[/tex] [since a=-5, d=-4]
[tex]=-5-16[/tex]
[tex]a_5=-21[/tex]
Therefore [tex]a_4=-17[/tex] and [tex]a_5=-21[/tex]
Therefore [tex]f(x)=\{-5,-9,-13,-17,-21,...\}[/tex]
Now to represent the sum of the first five terms of f(x) using sigma notation as below
[tex]f(x)=\sum_{n=1}^5 a_n[/tex]
where [tex]\sum_{n=1}^5 a_n=a_1+a_2+a_3+a_4+a_5[/tex]

The average of five weights is 13 grams. This set of of five weights is then increased by another weight of 7 grams. What is the average of the 6 weights?
Answer:
the answer is 12
Step-by-step explanation:
You just find the total weight and divide it by the number of weights
hope this helped ;3
Answer:
12 g
Step-by-step explanation:
Recall that
Average Weight = Sum of All weights ÷ Number of Weights
in the first case we are given that average of 5 weights is 13g
i.e Average weight (of 5 weights) = 13g and number of weights = 5
or, using the formula above,
13 = sum of 5 weights ÷ 5 (rearranging)
sum of 5 weights = 13 x 5 = 65 g
we are subsequently told that one more weight of 7 g is added,
hence, new number of weights = 6
and,
sum of 6 weights = sum of original 5 weights + sum of 6th weight
= 65 g + 7 g = 72 g
once again using the first formula
Average Weight (of 6 weights) = Sum of All weights ÷ Number of Weights
= 72 ÷ 6
= 12g

What is the domain and range of the function y = 2x2 - 4x - 10?
Answer:
Step-by-step explanation:
The domain of all polynomials is all real numbers. To find the range, let's solve that quadratic for its vertex. We will do this by completing the square. To begin, set the quadratic equal to 0 and then move the -10 over by addition. The first rule is that the leading coefficient has to be a 1; ours is a 2 so we factor it out. That gives us:
[tex]2(x^2-2x)=10[/tex]
The second rule is to take half the linear term, square it, and add it to both sides. Our linear term is 2 (from the -2x). Half of 2 is 1, and 1 squared is 1. So we add 1 into the parenthesis on the left. BUT we cannot ignore the 2 sitting out front of the parenthesis. It is a multiplier. That means that we didn't just add in a 1, we added in a 2 * 1 = 2. So we add 2 to the right as well, giving us now:
[tex]2(x^2-2x+1)=10+2[/tex]
The reason we complete the square (other than as a means of factoring) is to get a quadratic into vertex form. Completing the square gives us a perfect square binomial on the left.
[tex]x^2-2x+1=(x-1)^2[/tex] and on the right we will just add 10 and 2:
[tex]2(x-1)^2=12[/tex]
Now we move the 12 back over by subtracting and set the quadratic back to equal y:
[tex]2(x-1)^2-12=y[/tex]
From this vertex form we can see that the vertex of the parabola sits at (1,-12). This tells us that the absolute lowest point of the parabola (since it is positive it opens upwards) is -12. Therefore, the range is R={y|y ≥ -12}

14. a. Find the prime factorization of 180.
b. Explain why every natural number with a
zero in the ones place is a composite
number.
Answer:
a. 2² * 3² * 5; b. All numbers with a zero in the ones place is even.
Step-by-step explanation:
Final answer:
The prime factorization of 180 is 2 × 2 × 3 × 3 × 5. Every natural number with a zero in the ones place is a composite number because it can be divided evenly by 2 and at least one other number.
Explanation:
a. Prime factorization of 180:
To find the prime factorization of 180, we need to find the prime numbers that divide 180 evenly. Start by dividing 180 by the smallest prime number, 2. We get 180 ÷ 2 = 90. Then divide 90 by 2 again: 90 ÷ 2 = 45. Now, divide 45 by 3: 45 ÷ 3 = 15. Finally, divide 15 by 5: 15 ÷ 5 = 3. Therefore, the prime factorization of 180 is 2 × 2 × 3 × 3 × 5.
b. Explanation of why every natural number with a zero in the ones place is a composite number:
A composite number is a number that has more than two factors. Any natural number with a zero in the ones place can be divided evenly by 2 and at least one other number, making it a composite number. For example, 10 is divisible by 2 and 5, and 20 is divisible by 2 and 10. So, every natural number with a zero in the ones place is a composite number.
Priya Wants to buy three tickets for a concert she has earned 135 and each ticket cost 50 she borrows the rest of the money she needs from a bank and buys the tickets how can you represent them out of money that Priyahas after buying the tickets
Answer:
y=50x-135
Step-by-step explanation:
If each ticket costs 50 then for three tickets, Priya needs 3*50=150
However, since she earned 135, then she's less 150-135=15
The best way to present the money she borrowed is
y=50x-135
Where x is the number of tickets bought
Given the info, Priya needs to borrow $15 from the bank to afford all 3 tickets, so after purchasing, she's out of her own money and in debt to the bank.
Explanation:Essentially the question asks us how much money Priya has left after buying three concert tickets. Each ticket is priced at $50. She has earned $135 herself, so let's subtract the cost of the tickets from what she has earned.
We find that Priya needs to borrow $15 from the bank in order to purchase all three tickets (because $50 * 3 - $135 = $15).
So after buying the tickets, she would be out of her own money and $15 in debt to the bank.

[tex]\frac{2 \tan x}{1-\tan ^{2} x}+\frac{1}{2 \cos ^{2} x-1}=\frac{\cos x+\sin x}{\cos x-\sin x}[/tex] is proved
Solution:
Given that,
[tex]\frac{2 \tan x}{1-\tan ^{2} x}+\frac{1}{2 \cos ^{2} x-1}=\frac{\cos x+\sin x}{\cos x-\sin x}[/tex]
Let us first solve the L.H.S
[tex]\text { L. H.S }=\frac{2 \tan x}{1-\tan ^{2} x}+\frac{1}{2 \cos ^{2} x-1}[/tex] --- (1)
By trignometric identities,
[tex]\tan 2 x=\frac{2 \tan x}{1-\tan ^{2} x}[/tex]
[tex]\cos 2 x=2 \cos ^{2} x-1=\cos ^{2} x-\sin ^{2} x[/tex]
By using these in (1) we get,
[tex]\text { L. H.S }=\tan 2 x+\frac{1}{\cos 2 x}[/tex]
By definition of tan,
[tex]tan x = \frac{sinx}{cosx}[/tex]
Therefore,
[tex]L. H.S =\frac{\sin 2 x}{\cos 2 x}+\frac{1}{\cos 2 x}\\\\L. H . S=\frac{1+\sin 2 x}{\cos 2 x}$[/tex] --- (ii)
By trignometric identities,
[tex]\cos 2 x=2 \cos ^{2} x-1=\cos ^{2} x-\sin ^{2} x[/tex]
[tex]\begin{aligned}&\sin 2 x=2 \sin x \cos x\\\\&\cos ^{2} x+\sin ^{2} x=1\end{aligned}[/tex]
By using these in (ii)
[tex]\text { L. H.S }=\frac{\cos ^{2} x+\sin ^{2} x+2 \sin x \cos x}{\cos ^{2} x-\sin ^{2} x}[/tex] ----- (iii)
We know that,
[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]
Similarly,
[tex](cosx + sinx)^2 = cos^2x + 2cosxsinx + sin^2x[/tex]
Also,
[tex]a^2 - b^2 = (a+b)(a-b)[/tex]
Similarly,
[tex]cos^2x - sin^2x = (cosx+sinx)(cosx-sinx)[/tex]
Therefore apply these in (iii)
[tex]\begin{aligned}&\text { L. } H . S=\frac{(\cos x+\sin x)^{2}}{\cos ^{2} x-\sin ^{2} x}\\\\&\text { L. H.S }=\frac{(\cos x+\sin x)(\cos x+\sin x)}{(\cos x+\sin x)(\cos x-\sin x)}\end{aligned}[/tex]
Cancel out (cos x + sin x) on numerator and denominator
[tex]\text { L. H.S }=\frac{\cos x+\sin x}{\cos x-\sin x}[/tex]
[tex]\frac{2 \tan x}{1-\tan ^{2} x}+\frac{1}{2 \cos ^{2} x-1}=\frac{\cos x+\sin x}{\cos x-\sin x}[/tex]
Thus L.H.S = R.H.S
