Answer:
Can of Coke
Step-by-step explanation:
Calculate how much money each ounce of drink costs, or the money per ounce ($/oz).
Coke:
$/oz = $1 ÷ 12oz = $0.083333/oz
Pepsi:
$/oz = $1.35 ÷ 16oz = $0.084375/oz
Coke < Pepsi
0.083333 < 0.084375
The calculations show that you would pay more money for one ounce of Pepsi than for one ounce of Coke. Coke costs less than Pepsi.
Therefore the can of Coke is the best buy.
Final answer:
After calculating the cost per ounce for both the Coke and Pepsi, the 12 ounce can of Coke at $1.00 is the better buy as it costs approximately $0.0833 per ounce compared to the 16 ounce bottle of Pepsi at $1.35, which costs approximately $0.0844 per ounce.
Explanation:
To determine whether the can of Coke or the bottle of Pepsi is the better buy, we will calculate the cost per ounce for each.
For the 12 ounce can of Coke priced at $1.00, the cost per ounce is calculated as follows:
Divide the total cost by the number of ounces: $1.00 \/ 12 ounces.
This results in approximately $0.0833 per ounce for the Coke.
For the 16 ounce bottle of Pepsi priced at $1.35, the cost per ounce is calculated in a similar manner:
Divide the total cost by the number of ounces: $1.35 \/ 16 ounces.
You get approximately $0.0844 per ounce for the Pepsi.
Comparing the two, the cost per ounce of Coke is cheaper than the cost per ounce of Pepsi. Thus, the can of Coke is the best buy.
How do you write the difference of a number and eight, divided by ten
Answer:
(x-8)/10
Step-by-step explanation:
-------
(X - 8)/10 or (8 -X)/10
The unknown number can be given as X
The difference between the number and 8 can be given as 8 -X or X - 8
The dividing it by 10 will give (x-8)/10 or (8-x)/10 depending on the value of the unknown number X
What is the quotient?
StartFraction 2 y squared minus 6 y minus 20 Over 4 y + 12 EndFraction divided by StartFraction y squared + 5 y + 6 Over 3 y squared + 18 y + 27 EndFraction
The quotient is [tex]\frac{3(y-5)}{2}[/tex]
Explanation:
The expression is [tex]\frac{2 y^{2}-6 y-20}{4 y+12} \div \frac{y^{2}+5 y+6}{3 y^{2}+18 y+27}[/tex]
Now, reciprocal the term [tex]\frac{y^{2}+5 y+6}{3 y^{2}+18 y+27}[/tex] and convert ÷ to ×
[tex]\frac{2 y^{2}-6 y-20}{4 y+12} \times \frac{3 y^{2}+18 y+27}{y^{2}+5 y+6}[/tex]
Taking the common terms out, we get,
[tex]\frac{2\left(y^{2}-3 y-10\right)}{4(y+3)} \times \frac{3\left(y^{2}+6 y+9\right)}{y^{2}+5 y+6}[/tex]
Factorizing each numerator and denominator, we get,
[tex]\frac{2(y-5)(y+2)}{4(y+3)} \times \frac{3(y+3)(y+3)}{(y+3)(y+2)}[/tex]
Multiplying the terms, we have,
[tex]\frac{6(y-5)(y+2)(y+3)^{2}}{4(y+3)^{2}(y+2)}[/tex]
Cancelling the common factors, we get,
[tex]\frac{3(y-5)}{2}[/tex]
Thus, the quotient is [tex]\frac{3(y-5)}{2}[/tex]

A cat weighs 3.5 ounces when born. The cat grows 0.5 ounces each week. After
how many weeks does the cat way 16.5 ounces?
Answer:
10 weeks
Step-by-step explanation:
Answer: 26 weeks
Step-by-step explanation:
This is an example of an arithmetic sequence.
The first term = 3.5
common difference = 0.5
Using the formula for calculating the nth term of an arithmetic sequence :
[tex]t_{n}[/tex] = a + (n - 1 ) d
Therefore :
16.5 = 3.5 + ( n - 1 ) x 0.5
16. 5 = 3.5 + 0.5n - 0.5
16.5 = 3 + 0.5n
16.5 - 3 = 0.5n
13.5 = 0.5n
n = 13.5/0.5
n = 27
Therefore , it will take the cat (n-1) weeks to weigh 16.5 ounce, which will be 27 - 1 = 26
check:
3.5 + 26 ( 0.5)
= 3.5 + 13
= 16.5

Question 3
Answer: Choice A) {(3,4) (3,5)}-----------
Explanation:
Note how in choice A we have repeated x values
x = 3 pairs up with y = 4 and y = 5 at the same time.
The input x = 3 must only pair up with one output only if we want a function to happen.
If you plotted the points (3,4) and (3,5), it is possible to draw a vertical line through them. So this fails the vertical line test.
The other answer choices do not have repeated x values, so they are all functions.
==========================================
Question 4
Answer: choice A) 2x+3y = 10 and choice D) y = 18-----------
If you plotted choice A and choice D on an xy coordinate system, you should see straight lines forming.
2x+3y = 10 turns into y = (-2/3)x+10/3 which is y = mx+b form.
Choice D's equation is equivalent to y = 0x+18, so its slope here is 0, making it a flat horizontal line.
Choice B does not count as an answer because while it is a linear vertical line, it is not a function for similar reasons back in question 3. The fact that x = 16 pairs up with infinitely many y values is what makes this not be a function.
Choice C is not a linear equation. Instead it is a quadratic equation because the largest exponent is 2.

The length of a rectangle is 3 1/6 cm longer than the width. The perimeter of the rectangle is 15 1/3 cm. What are the width and length of this rectangle?
The width of rectangle is [tex]2\frac{1}{4}\ cm[/tex] and length is [tex]5\frac{5}{12}\ cm[/tex]
Step-by-step explanation:
Let,
Width of rectangle = w
Length of rectangle = w+[tex]3\frac{1}{6}=w+\frac{19}{6}[/tex]
Perimeter of rectangle = [tex]15\frac{1}{3}=\frac{46}{3}\ cm[/tex]
Perimeter of rectangle = 2(Length + Width)
[tex]2(w+\frac{19}{6}+w)=\frac{46}{3}\\2(2w+\frac{19}{6})=\frac{46}{3}\\4w+\frac{19}{3}=\frac{46}{3}[/tex]
Subtracting [tex]\frac{19}{3}[/tex] from both sides
[tex]4w+\frac{19}{3}-\frac{19}{3}=\frac{46}{3}-\frac{19}{3}\\4w=\frac{46-19}{3}\\4w=\frac{27}{3}\\4w=9[/tex]
Dividing both sides by 4
[tex]\frac{4w}{4}=\frac{9}{4}\\w=\frac{9}{4}[/tex]
Therefore,
Width of rectangle = w = [tex]\frac{9}{4}=2\frac{1}{4}[/tex] cm
Length of rectangle = [tex]w+\frac{19}{6}=\frac{9}{4}+\frac{19}{6}=\frac{27+38}{12}=\frac{65}{12}=5\frac{5}{12}\ cm[/tex]
The width of rectangle is [tex]2\frac{1}{4}\ cm[/tex] and length is [tex]5\frac{5}{12}\ cm[/tex]

7. The sun is at an angle of elevation of 58º. A tree casts a shadow 20 meters long on
the ground. How tall is the tree?
The height of tree is 32 meter
Solution:
Given that, The sun is at an angle of elevation of 58 degree
A tree casts a shadow 20 meters long on the ground
The sun, tree and shadow forms a right angled triangle
The figure is attached below
ABC is a right angled triangle
AC is the height of tree
AB is the length of shadow
AB = 20 meters
Angle of elevation, angle B = 58 degree
By definition of tan,
[tex]tan \theta = \frac{opposite}{adjacent}[/tex]
In this right angled triangle ABC,
opposite = AC and adjacent = AB
Therefore,
[tex]tan\ 58 = \frac{AC}{AB}\\\\tan\ 58 = \frac{AC}{20}\\\\1.6 = \frac{AC}{20}\\\\AC = 1.6 \times 20\\\\AC = 32[/tex]
Thus height of tree is 32 meter
Final answer:
To determine the height of the tree using the angle of elevation of the sun and the shadow length, apply the tangent function. With an elevation of 58º and a shadow of 20 meters, the tree’s height is calculated to be approximately 33.94 meters.
Explanation:
To find the height of the tree given the angle of elevation of the sun and the length of the shadow it casts, we can make use of trigonometry. Specifically, we will use the tangent function, which relates the angle of elevation with the opposite side (the height of the tree) and the adjacent side (the length of the shadow).
Step-by-step solution:
Let's denote the height of the tree as H and the length of the shadow as 20 meters.The angle of elevation of the sun is given as 58º.Using the tangent function: tan(θ) = opposite/adjacent, where θ is the angle of elevation.Plugging in the values, we get tan(58º) = H / 20 meters.Solve for H by multiplying both sides by 20 meters: H = 20 meters · tan(58º).Use a calculator to find tan(58º), and then compute H.After calculating, we find that the height of the tree is approximately 33.94 meters.Thus, the height of the tree is approximately 33.94 meters.

the consecutive odd integers have a sum of 36. find the integers
how many consecutive odd integers are there, or else I can't help you
==================================================
Work Shown:
x = some integer
2x = even integer
2x+1 = odd integer
(2x+1)+2 = 2x+3 = odd integer just after 2x+1
The integers 2x+1 and 2x+3 add to 36
(2x+1)+(2x+3) = 36
2x+2x+1+3 = 36
4x+4 = 36
4x+4-4 = 36-4 ... subtract 4 from both sides
4x = 32
4x/4 = 32/4 .... divide both sides by 4
x = 8
With x = 8, we can say
2x+1 = 2*8+1 = 17 is the first odd integer
2x+3 = 2*8+3 = 19 is the next odd integer
17+19 = 36, so the answer is confirmed
--------------------
A non-algebraic way to get the answer is to divide 36 in half to get 18
Then try odd integers around 18, so 19+21 = 40 but thats too high
then maybe try 15+17 = 32, thats too low
17+19 = 36 is right on the money

ZCIS
ZCSI
Lisc
Answer:
∠CIS.
Step-by-step explanation:
This angle is opposite from the smallest side. Therefore, according to the triangle inequality, it is the smallest angle.
The smallest angle that the angular momentum vector can make with the z-axis for an electron with quantum number l=2 is found using the magnetic quantum numbers. For m₁=+2, the angle would be the smallest, approaching 0 degrees.
Explanation:The question pertains to the calculation of the smallest angle that the angular momentum vector ℓ can make with the z-axis given the quantum number l for an electron. To find this, we use the concept of quantized angular momentum in quantum mechanics.
For an electron with a quantum number l=2, it can have multiple magnetic quantum numbers m₁, ranging from -l to +l. Therefore, for l=2, m₁ can be -2, -1, 0, 1, or 2. Each of these values corresponds to a different angle with the z-axis.
The smallest angle corresponds to the maximum value of m₁, which is 2 in this case. The formula cos 0 = Lz/L uses the magnetic quantum number m₁ and the total angular momentum to calculate the cosine of the angle. For m₁=+1, the value of cos 0 would be 0.707, using the provided ratios and simplifying the formulas given. This corresponds to an angle whose cosine is 0.707, which through the inverse cosine function can be determined to be approximately 45 degrees. However, for m₁=+2, the angle would be even smaller, approaching 0 degrees as the z-component of angular momentum becomes maximally aligned with the z-axis.

How can u solve 40x16 by breaking apart the numbers
Answer: 640
Step-by-step explanation:
You can break 16 up into 10 and 6: 40(10+6)
40(10)+40(6)
400+240
640
Final answer:
To solve 40x16, break apart the numbers into tens and use the distributive property to calculate the partial products, then sum up these products to get the final result of 640.
Explanation:
To solve 40x16 by breaking apart the numbers, you can use a strategy known as decomposing or partial products. Here's a step-by-step explanation:
Break apart the number 40 into 10s: 40 = 30 + 10.
Break apart the number 16 into 10s: 16 = 10 + 6.
Now use the distributive property to multiply each part:
(30 + 10) × (10 + 6)
Multiply each part individually: 30 x 10, 30 x 6, 10 x 10, and 10 x 6.
Calculate the partial products: 300, 180, 100, and 60.
Finally, add all the partial products: 300 + 180 + 100 + 60 = 640.
So, 40x16 equals 640 when you apply the breaking apart method.

Solve the system of linear equations by substitution.
5x+2y=9
x+y= -3
Answer:
Step-by-step explanation:
5x+2y=9.......(1)
x+y= -3.........(2)
Making y as subject bin (2)
y = -3 - x
Substituting in (1)
5x + 2(-3 - x) = 9
5x - 6 - 2x = 9
3x = 9 + 6
3x = 15
x = 15/3
x = 5
And y = -3 - x
y = -3 - 5
y = -8
Answer:
The solution for the system of linear equations is x = 5, y = -8
Step-by-step explanation:
Let's solve the system of linear equations by substitution:
5x + 2y = 9
x + y = -3
Solving for x in the 1st equation, this way:
5x + 2y = 9
5x = 9 - 2y
x = (9 - 2y)/5
Substituting x in the 2nd equation:
x + y = -3
(9 - 2y)/5 + y = -3
9 - 2y + 5y = - 15 (Multiplying by 5 at both sides)
3y = - 15 - 9
y = -24/3
y = - 8
Substituting y in the 1st equation:
5x + 2y = 9
5x + 2 * - 8 = 9
5x - 16 = 9
5x = 25
x = 25/5 = 5
The solution for the system of linear equations is x = 5, y = -8

Answer:
The nth term of the given arithmetic sequence is [tex]a_n=-17+(n-1)9[/tex]
Step-by-step explanation:
Given sequence is -17,-8,1,...
To find the nth term of the given sequence :
Let [tex]a_1=-17,a_2=-8,a_3=1,...[/tex]
To find the common difference d :
[tex]d=a_2-a_1[/tex]
[tex]=-8-(-17)[/tex]
[tex]=-8+17[/tex]
Therefore d=9
[tex]d=a_3-a_2[/tex]
[tex]=1-(-8)[/tex]
[tex]=1+8[/tex]
Therefore d=9
The common difference d is 9
Therefore the given sequence is an arithmetic sequence
The nth term of an arithmetic sequence is given below
[tex]a_n=a_1+(n-1)d[/tex]
Substitute [tex]a_1=-17[/tex] and d=9 in the above equation we get
[tex]a_n=-17+(n-1)9[/tex]
Therefore the nth term of the given arithmetic sequence is [tex]a_n=-17+(n-1)9[/tex]
The formula for the nth term of the sequence -17, -8, 1 is a_n = 9n - 26, where n is the position of the term in the sequence.
Explanation:The sequence provided is -17, -8, 1, which suggests that there is a common difference between terms since it is an arithmetic sequence. To find the nth term of an arithmetic sequence, we use the formula a_n = a_1 + (n - 1)d, where a_n is the nth term, a_1 is the first term, and d is the common difference. In this case, the common difference is 9 (since -8 - (-17) = 9).
So, using the formula for the nth term of an arithmetic sequence:
a_1 = -17 (the first term)d = 9 (the common difference)Our formula becomes a_n = -17 + (n - 1) × 9. Simplifying this:
a_n = -17 + 9n - 9
a_n = 9n - 26
Therefore, the formula for the nth term of the given sequence is a_n = 9n - 26.
