Answer:
Product A.
Step-by-step explanation:
The unit price of product A is $1.36/8oz = $0.17/oz.
The unit price of product B is $3.20/16oz = $0.20/oz.
Answer:
not 100% about this answer but I think it is the 8oz bottle
Step-by-step explanation:
take $1.36 and divide it by 8 which gives you .17 which is 17 cents per oz now do the same thing for the 16 oz so take $3.20 and divide it by 16 and you get .2 which is 20 cents per oz so the 8oz has the lowest unit price of the two!

[tex]x=7.5\ un.[/tex]
[tex]y=\dfrac{15\sqrt{3}}{4}\ un.[/tex]
[tex]z=\dfrac{15\sqrt{3}}{2}\ un.[/tex]
Step-by-step explanation:
Given triangle is special 30°-60°-90° right triangle. The leg that is opposite to the angle of measure 30° is always equal to half of the hypotenuse. The hypotenuse is of length 15 units, the leg that is opposite to the 30° angle is leg with length of x units, then
[tex]x=\dfrac{15}{2}=7.5\ un.[/tex]
In right triangle with hypotenuse x and legs y and a, angle opposite to the leg a is 30°, then
[tex]a=\dfrac{x}{2}=\dfrac{7.5}{2}=3.75\ un.[/tex]
and
[tex]b=15-a=15-3.75=11.25\ un.[/tex]
By the Pythagorean theorem,
[tex]x^2=y^2+a^2,\\ \\7.5^2=3.75^2+y^2,\\ \\y^2=\left(\dfrac{15}{2}\right)^2-\left(\dfrac{15}{4}\right)^2=\dfrac{225}{4}-\dfrac{225}{16}=\dfrac{675}{16},\\ \\y=\dfrac{15\sqrt{3}}{4}\ un.[/tex]
In right triangle with legs y and b and hypotenuse z, leg y is opposite to 30° angle, then
[tex]z=2y=\dfrac{15\sqrt{3}}{2}\ un.[/tex]
Answer:
[tex]a=3.75[/tex]
Step-by-step explanation:
The hypotenuse of the large triangle is 15.
We can see that the side opposite of 30° angle is [tex]x[/tex]
Trigonometric ratio of SINE relates opposite and hypotenuse.
Thus we can write and cross multiply and solve:
[tex]sin(A)=\frac{Opposite}{Hypotenuse}\\sin(30)=\frac{x}{15}\\x=15*sin(30)=7.5[/tex]
Now if you see the smallest triangle, [tex]a[/tex] is the adjacent side and [tex]x[/tex] becomes the hypotenuse of this triangle.
Trigonometric ratio of COSINE relates adjacent and hypotenuse.
Thus we can write and cross multiply and solve:
[tex]cos(A)=\frac{Adjacent}{Hypotenuse}\\cos(60)=\frac{a}{7.5}\\a=7.5*cos(60)=3.75[/tex]
Thus [tex]a=3.75[/tex]

In ΔABC, m∠ACB = 90°, CD ⊥ AB and m∠ACD = 45°. Find AC, if CD = 6 sqrt 3
Final answer:
Since ΔACD is an isosceles right triangle, the two legs AC and CD are equal. Given CD = 6 √ 3, AC is also 6 √ 3 units.
Explanation:
In triangle ΔABC, we are given that m∠ACB = 90°, meaning that ΔACB is a right-angled triangle. We are also given that CD is perpendicular to AB and that m∠ACD = 45°. Since CD is perpendicular to AB at D, triangle ΔACD is also a right-angled triangle with a 45° angle, which makes it an isosceles right triangle. In an isosceles right triangle, the lengths of the legs are equal. Therefore, AC will be equal to CD which is given as 6 √ 3.
The length of AC in triangle ΔACB can be found using Pythagoras' theorem, AC = √(AB² + BC²). But here we need only the length of AC in the right-angled ΔACD where AC equals CD.
Hence, AC = 6 √ 3 units.

An airplane must clear a 60-foot pole at the end of a runway 500 yards long determine the angle of elevation at which the airplane must ascend to clear the pole.
Answer:
2.3 degrees.
Step-by-step explanation:
Please find the attachment.
We are told that an airplane must clear a 60-foot pole at the end of a runway 500 yards long.
Let us convert 500 yards to feet.
1 yard= 3 feet.
500 yards= 3*500 feet= 1500 feet.
We can see from our attachment pole and runway are in form of a right triangle. The pole is opposite to angle of elevation of plane and length of runway is adjacent.
Since tangent represents the relation between opposite and adjacent of right triangle, So we will use tangent to find angle of elevation that plane must ascend to clear the pole.
[tex]tan(\theta)=\frac{60}{1500}[/tex]
[tex]\theta=\tan^{-1}(\frac{60}{1500} )[/tex]
[tex]\theta=\tan^{-1}(0.04)[/tex]
[tex]\theta=2.290610042639[/tex]
Therefore, the airplane must ascend 2.3 degrees to clear the pole.

What is the common difference for the arithmetic sequence?
Answer:
-2.4
Step-by-step explanation:
The difference between any two consecutive terms (following - preceding) is -2.4. The negative sign corresponds to the observation that the sequence is decreasing.
The common difference in an arithmetic sequence is the consistent difference between consecutive terms of the sequence. It's calculated by subtracting a term from its subsequent term. For example, in the sequence 3, 5, 7, 9, the common difference is 2.
Explanation:In the field of mathematics, specifically in sequences, the common difference refers to the difference between consecutive terms in an arithmetic sequence. An arithmetic sequence is a list of numbers in which each term is obtained from the previous one by adding a fixed number.
To find the common difference, you simply subtract the second term from the third, or the first from the second. For instance, if your arithmetic sequence is 3, 5, 7, 9, the common difference would be 5-3 or 7-5, which both yield a common difference of 2.

Answer:
The number of questions in sixth assignment must be less than or equal to 28.
Step-by-step explanation:
The number of questions in first five assignments are 11,10,13,14 and 14.
It is given that Mrs hawk assigns her students an average of no more than 15 questions on each assignment. Therefore the average of six assignments is less than or equal to 15 questions.
Let the number of questions in sixth assignment be x
[tex]\text{Average}=\frac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
Average of six assignments are
[tex]A=\frac{11+10+13+14+14+x}{6}[/tex]
[tex]A=\frac{62+x}{6}[/tex]
Since the average of questions is no more than 15, therefore
[tex]A\leq 15[/tex]
[tex]\frac{62+x}{6}\leq 15[/tex]
[tex]62+x\leq 90[/tex]

Therefore the number of questions in sixth assignment must be less than or equal to 28.
Find the earnings for selling the same number of each type of sandwich use x to represent the number of each sandwich sold
The earnings for selling the same number of each type of sandwich, considering both Turkey and Ham with Pretzel Roll and Bagel options, amount to $48. This is derived from a simplified expression of $29.10x, factored by 11, indicating a total revenue of $4.30 per sandwich.
Earnings for Selling Sandwiches
1: Identify the Given Information
We have two types of sandwiches: Turkey and Ham.
Each type comes in two types of bread: Pretzel Roll and Bagel.
Prices are provided for each combination:
Turkey Pretzel: $2.25
Turkey Bagel: $2.00
Ham Pretzel: $1.55
Ham Bagel: $1.30
2: Represent the Number of Sandwiches with a Variable
Let x represent the number of each type of sandwich sold (both Turkey and Ham, regardless of bread).
3: Calculate Earnings for Each Type of Sandwich
Turkey Sandwich: $11 (given price) * x (number sold) = $11x
Ham Sandwich: $11 (given price) * x (number sold) = $11x
Step 4: Calculate Earnings for Each Bread Type (excluding overlapping information)
Pretzel Roll: (Earnings from Turkey Pretzel + Earnings from Ham Pretzel) = ($2.25 * x) + ($1.55 * x) = $3.80x
Bagel: (Earnings from Turkey Bagel + Earnings from Ham Bagel) = ($2.00 * x) + ($1.30 * x) = $3.30x
5: Combine Earnings for Total Revenue
Total Earnings = Earnings from Turkey Sandwiches + Earnings from Ham Sandwiches + Earnings from Pretzel Rolls + Earnings from Bagels
Total Earnings = $11x + $11x + $3.80x + $3.30x = $29.10x
6: Simplify the Expression
Total Earnings = $29.10x
Since we are selling the same number of each type of sandwich, 11 is a common factor in all four terms.
We can factor out 11 to obtain:
Total Earnings = 11 * ($2.65 + $1 + $0.35 + $0.30) = 11 * $4.30 = $48
Therefore, the earnings for selling the same number of each type of sandwich are $48.
