The price of the 4rth item is $0.50.
How to find the price of the 4rth item?The three prices add to 1.50 + 3.00 + 4.00 = $8.50.
The three prices multiply to 1.50 x 3.00 x 4.00 = $18.00.
You might see that adding another $0.50 will take the total to $9.00, and multiplying by another $0.50 will take the product to $9.00 also, but the answer can also be found using algebra. Let's call the unknown price P:
1.50 + 3.00 + 4.00 + P = 1.50 x 3.00 x 4.00 x P
8.50 + P = 18.00 x P
8.50 = 18.00 x P - P
8.50 = 17.00 x P
8.50/17.00 = P
P = 0.50.

Final answer:
To solve the puzzle, we create an equation with the fourth price as 'x' and set the sum of the prices equal to the product of the prices. After simplifying, we find that the fourth item must cost $2.00 to satisfy the condition.
Explanation:
The student is faced with a mathematical puzzle involving the addition and multiplication of prices of items purchased. The condition is that the prices added together equals the product of the prices. Given three of the prices as $1.50, $3.00, and $4.00, let us assume the price of the fourth item is x. Therefore:
Sum of prices: $1.50 + $3.00 + $4.00 + xProduct of prices: $1.50 × $3.00 × $4.00 × xThe equation to solve is:
$1.50 + $3.00 + $4.00 + x = $1.50 × $3.00 × $4.00 × x
Simplifying the equation:
$8.50 + x = $18.00 × x
Subtracting $8.50 from both sides gives us:
x = $18.00 × x - $8.50
Dividing both sides by x:
1 = $18.00 - $8.50 / x
Finally, solving for x:
x = $18.00 / ($18.00 - 1)
x = $2.00
Thus, the price of the fourth item is $2.00.

Answer:
No he is not correct.
Step-by-step explanation:
Both points lie at point -8. Knowing this, we also know that to find the answer we would subtract the two coordinates not add them. We do this because they lie in the same quadrant. Therefore, | 12 | - | - 3.5 | = 8.5 units apart.
A scientist calculated the mean and standard deviation of a data set to be Mu = 120 and Sigma = 9. She then found that she was missing one data value from the set. She knows that the missing data value was exactly 3 standard deviations away from the mean. What was the missing data value?
Answer:
The missing data value is 147
Step-by-step explanation:
The mean is 120
The standard deviation is 9
Missing data value = ?
From the question, the missing data value is 3 standard deviation away from the mean.
3 standard deviation = 3 * 9 = 27
3 standard deviation from the mean = 120 + 27 = 147
The missing data value is what we get after adding 3 standard deviation from the mean.

Find the area(ignore the line if you want)
Given:
Image of the figure
To find:
The area of the figure.
Solution:
The image is splitted into two shapes.
One is rectangle and the other is trapezium.
Reference image for answer is attached below.
Rectangle:
Length = 10 cm
Width = 2.8 cm
Area = length × width
= 10 × 2.8
Area = 28 cm²
Trapezium:
Top base = 6 cm
Bottom base = 10 cm
Height = 7.2 - 2.8 = 4.4 cm
Area = [tex]\frac{1}{2} \times\left(b_{1}+b_{2}\right) \times h[/tex]
[tex]$=\frac{1}{2} \times(6+10) \times 4.4[/tex]
[tex]$=\frac{1}{2} \times 16 \times 4.4[/tex]
Area = 35.2 cm²
Area of the figure = 28 cm² + 35.2 cm²
= 63.2 cm²
The area of the figure is 63.2 cm².
The circumference of the moon is about 6,790 miles Find the diameter of the moon to the nearest mile. help somebody
Answer:
2162 miles
Step-by-step explanation:
The equation of the circumference of a circle is d*pi = Circumference. Knowing this, We can do a one step equation and divide be pi on both sides to find the diameter. All you have to do is plug the numbers in and divide 6790 by 3.14 to find 2162. (Rounded to the nearest mile)
Final answer:
To find the diameter of the moon, use the formula for circumference. Given the circumference of the moon, substitute the value into the formula to find the radius. Multiply the radius by 2 to find the diameter. Round the result to the nearest mile.
Explanation:
To find the diameter of the moon, we can use the formula for circumference: Circumference = 2πr, where r is the radius. Given that the circumference of the moon is about 6,790 miles, we can rearrange the formula to solve for the diameter. Since diameter is twice the radius, we have Diameter = 2r. Substitute the given circumference value into the formula to find the radius. Then multiply the radius by 2 to find the diameter. Round the result to the nearest mile.
Step 1: Circumference = 2πr
Step 2: Given circumference = 6,790 miles
Step 3: Solve for r: 6,790 miles = 2πr
Step 4: Divide both sides of the equation by 2π: r ≈ 1,080 miles
Step 5: Multiply r by 2 to find the diameter: Diameter ≈ 2 * 1,080 miles ≈ 2,160 miles
Therefore, the diameter of the moon, rounded to the nearest mile, is approximately 2,160 miles.

A restaurant offers 10 appetizers and 12 main courses. In how many ways can a person order a two-course meal? Use the Fundamental Counting Principle with two groups of items.
Answer:
80 ways
Step-by-step explanation:
The first thing is to apply the Fundamental Counting Principle with two groups of items, in this case the multiplication rule is used.
In this case, what we should do is that, for every 1 main course there are 8 appetizers, but there are 10 main courses therefore:
8 * 10 = 80
There are 80 ways to combine appetizers and the main course
Final answer:
A person can order from a restaurant 120 different two-course meals using the Fundamental Counting Principle, as there are 10 appetizers and 12 main courses to choose from.
Explanation:
The question is asking how many different two-course meals can be ordered if a restaurant offers 10 appetizers and 12 main courses. According to the Fundamental Counting Principle, if there are separate events and the first event can occur in 'm' ways and the second in 'n' ways, then the events together can occur in a total of m x n ways.
Using this principle:
Number of ways to select an appetizer = 10
Number of ways to select a main course = 12
Therefore, the total number of two-course meal combinations = 10 appetizers x 12 main courses = 120 combinations
So, a person can order 120 different two-course meals from this restaurant.

(x - 2)(x - 2 + x + 4) = 4(4 + 5)
(x - 2)(2x + 2) = 4(9) = 36 ← distribute and simplify the left side
2x² + 2x - 4x - 4 = 36
2x² - 2x - 4 = 36 ( subtract 36 from both sides )
2x² - 2x - 40 = 0 ( divide through by 2 )
x² - x - 20 = 0 ← in standard form
(x - 5)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 4 = 0 ⇒ x = - 4
But x > 0 ⇒ x = 5

If one bottle of paint covers an area of 40 square feet, how many bottles of paint does Andre need for his backdrop? Enter your numerical answer with no label.
Group of answer choices
Answer:
2.1375 bottles of paint
Step-by-step explanation:
cardboard length = 14 1/4 ft, which is equivalent to (4*14 + 1)/4 = 57/4 ft
cardboard width = 6 ft
Rectangular cardboard area = length * width = 57/4 * 6 = (57*6)/4 = 342/4 ft², which can be simplified dividing numerator and denominator by 2: 171/2 ft²
If 1 bottle of paint covers an area of 40 square feet, then to paint 171/2 square feet the following proportion must be satisfied:
1 bottle of paint / 40 square feet = x bottles of paint / (171/2) square feet
x = (1/40) * (171/2) = (1*171)/(40*2) = 171/80 or (160 + 11)/80 = 160/80 + 11/80 = 2 11/80 or 2.1375 bottles of paint

You are preparing small and large cupcakes for the school bake sale. If you will need 1/3 a spoon of sugar for each small cupcake, and 1/2 a spoon of sugar for the large cupcake.if you need to make 30 small cupcakes and 20 large cupcakes, and you have a total of 21 spoons of sugar. Is this enough to make your cupcakes?
Answer:
yes
Step-by-step explanation:
1/3x30 is 10 which would be 10 spoons
1/2x20 is also 10 which would be another 10 spoons
10+10 equals 20
you have 21 spoons which means that you will have enough spoons of sugar to make all 50 cupcakes
Answer:
Yes as the small cupcakes would need 10 spoons (=1/3 of 30) where the large cupcakes would need 10 spoons of sugar (=1/2 of 20).
Step-by-step explanation:
30 x 1/3 = 10
30 x 1/2 = 10
10+10 =20
= 20 spoons of sugar makes 10 of each size cupcakes, so 21 spoons mentioned in the question would be enough.

Answer:
0°
360°
Step-by-step explanation:
We want to solve the equation,
[tex] \cos(x + 45) + \cos(x - 45) = \sqrt{2} [/tex]
We expand using trigonometric identities to get;
[tex]\cos(x) \cos( 45) - \sin(x) \sin(45) + \cos(x) \cos( 45) + \sin(x) \sin(45) = \sqrt{2} [/tex]
[tex] \frac{ \sqrt{2} }{2} \cos(x) - \frac{ \sqrt{2} }{2} \sin(x) + \frac{ \sqrt{2} }{2} \cos(x) + \frac{ \sqrt{2} }{2} \sin(x) = \sqrt{2} [/tex]
Simplify;
[tex] \cos(x) - \sin(x) + \cos(x) + \sin(x) = 2[/tex]
Simplify;
[tex]\cos(x) + \cos(x) = 2[/tex]
Add
[tex]2\cos(x) = 2[/tex]
Divide by 2
[tex]\cos(x) = 1[/tex]
Take cosine inverse;
In the
[tex]x = \cos^{ - 1} ( 1) =0\degree [/tex]
Also in the 3rd quadrant cosine ratio is positive.
[tex]x = 360-0= 360 \degree[/tex]
