Final answer:
To find the price per dozen, divide the sale price of $2.55 by 4 to get the price per muffin, then multiply by 12. The price per dozen muffins is $7.65.
Explanation:
To calculate the price per dozen muffins at the bakery when the sale price is $2.55 for 4 muffins, you first need to determine the price of one muffin. You can do this by dividing the sale price by the number of muffins in the offer:
$2.55 ÷ 4 = $0.6375 per muffin.
Next, because a dozen consists of 12 items, you would find the price per dozen by multiplying the price per muffin by 12:
$0.6375 × 12 = $7.65
Therefore, the price per dozen muffins is $7.65.
Find the next term of the following sequence.
25, 10, 4,
The given sequence is 25, 10, 4.
Notice that this is a geometric sequence because here we have equal common ratio.
So, common ratio : r = [tex] \frac{a_{2}}{a_{1}} [/tex]
= [tex] \frac{10}{25} [/tex]
= 0.4
So, each term is 0.4 times of it's previous term.
Hence, to get the next term of this sequence, multiply 0.4 with the third term 4.
So, fourth / next term = 4* 0.4 =1.6
Hence, next term of this sequence is 1.6.
Hope this helps you!

There are 20 girls on the basketball team. of these, 17 are over 16 years old, 12 are taller than 170 cm, and 9 are both older than 16 and taller than 170 cm. how many of the girls are older than 16 or taller than 170 cm?
Final answer:
By using the principle of inclusion-exclusion, we calculate that all 20 girls on the basketball team are either over 16 years old or taller than 170 cm, as the sum of the individual criteria minus the intersection equals the total number of girls on the team.
Explanation:
To determine how many of the girls on the basketball team are either over 16 years old or taller than 170 cm, we can use the principle of inclusion-exclusion. According to the information provided, there are 20 girls on the team in total, of which 17 are over 16 years old, 12 are taller than 170 cm, and 9 satisfy both criteria. The principle of inclusion-exclusion states that the number of elements in the union of two sets is equal to the sum of the sizes of each set minus the size of their intersection.
Using this principle:
Number of girls over 16 years old: 17
Number of girls taller than 170 cm: 12
Number of girls who are both over 16 and taller than 170 cm: 9
The calculation would be as follows:
17 (over 16) + 12 (taller than 170 cm) - 9 (both) = 20
Therefore, there are 20 girls on the team who are either older than 16 or taller than 170 cm.
John buys big ice-cream cylindrical Jar and sells it for $1 each ice-cream cone.
Each cone has around 30 cubic cm of ice-cream in it.
Jar has diagonal 20 cm. and its height is 3 times of width.
If he sells the whole jar, and He originally bought it for $7 does he make profit out of selling the jar?
John can make a profit by selling ice cream from the cylindrical jar. After calculating the volume, he would earn approximately $15.70 in revenue, and by deducting the initial cost ($7), he makes a profit of around $8.70.
To determine if John will make a profit by selling the entire ice-cream cylindrical jar, we first need to calculate the volume of the jar to find out how many cones he can fill. The jar has a diagonal of 20 cm and a height that is three times its width. Assuming the width is 'w' and height is '3w', we can use the Pythagorean theorem with the jar's diagonal to find 'w', since the diagonal forms a right triangle with the width and height of the cylinder.
The formula for the Pythagorean theorem is diagonal^2 = width^2 + height^2, which gives us 20^2 = w^2 + (3w)^2. Solving for 'w', we get w = 4 cm and height = 12 cm. The volume 'V' of the cylinder is given by V = π * radius^2 * height, which gives us V = π * 2^2 * 12, therefore, V = 48π cm^3. Then, we divide the jar's volume by the volume of each ice cream cone to find the number of cones, 48π cm^3 / 30 cm^3/cone ≈ 5π cones.
Given that John sells each cone for $1, the total revenue from selling all the ice-cream cones would be approximately $5π. Since π is approximately 3.14, his total revenue would be about $15.70. Subtracting the initial cost of the jar ($7), we find that John would make a profit of approximately $8.70.
Therefore, John will indeed make a profit out of selling the jar of ice cream.

Elliott purchased shares of Microsoft in 2008 for $28 per share. He plans to sell them as soon as the price rises 20%. At what price will he sell his shares?
Since we are to find the price when it is risen 20%, therefore the fractional increase must be 0.20 of the original, therefore:
amount increased = $28 * 0.20 = $5.60
So the selling price must be:
selling price = $28 + $5.60 = $33.60
Final answer:
Elliott will sell his Microsoft shares at a price of $33.60 each after a 20% price increase from his initial purchase price of $28 per share.
Explanation:
The question concerns the calculation of a future selling price of shares after a certain percentage increase. To find the selling price after a 20% increase on Elliott's initial purchase price of $28 per share, we first calculate the 20% increase, which is 0.20 × $28 = $5.60. Next, we add this increase to the original purchase price to determine the selling price: $28 + $5.60 = $33.60 per share. Therefore, Elliott plans to sell his shares when their price reaches $33.60 each.

Answer:
A(0, -3) ; B(3, -2) and C(1, -1).
Step-by-step explanation:
Given : ΔABC with vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise about the origin.
To find : What are the coordinates of the vertices of the image.
Solution : We have given
Vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise.
By the rotation rule of 180° clockwise : (x ,y) →→ ( -x ,-y).
Then vertices would be
A(-3, 0) →→ A(3, 0)
B(-2, 3) →→ B(2, -3)
C(-1, 1) →→ C(1, -1).
Reflection y = -x then
A(0, -3) ; B(3, -2) and C(-1, 1).
Therefore, A(0, -3) ; B(3, -2) and C(1, -1).
A survey was taken on pet ownership. 750 people were covered on the first day of the survey. The number tripled every subsequent day. Find the total number of people surveyed in 6 days
A. 265100
B. 265200
C. 273000
D. 265700
To find the total number of people surveyed in 6 days with numbers tripling each day starting with 750, we calculate the number for each day and sum them up, giving a total of 273000 people surveyed.
To calculate the total number of people surveyed in 6 days if 750 people were covered on the first day and the number tripled every subsequent day. We will use an exponential growth formula to find the answer.
On Day 1: 750 people.
On Day 2: 750 × 3 = 2250 people.
On Day 3: 2250 × 3 = 6750 people.
On Day 4: 6750 × 3 = 20250 people.
On Day 5: 20250 × 3 = 60750 people.
On Day 6: 60750 × 3 = 182250 people.
To find the total number of people surveyed over the 6 days, we add up the total number of people surveyed each day:
750 + 2250 + 6750 + 20250 + 60750 + 182250 = 273000 people.
Therefore, the correct answer is C. 273000.

HELP MEH PLEZ! When the county fair opened its gates, 68 people entered the fairgrounds. After one hour, there were 1.5 times as many people on the fairgrounds as when the gates opened. After two hours, there
The equation representing the number of people, y, at the fair x hours after the gates open:
y = 68 * 1.5^(x-1)
Initial number of people: 68 (given)
Growth factor per hour: 1.5 (given)
Number of hours since gates opened: x
The equation uses the following logic:
Start with the initial number of people (68).
Multiply by the growth factor (1.5) to account for the increase after the first hour.
Since the growth factor applies after each hour, raise it to the power of (x-1) to account for the total number of times it's applied after x hours. This is because the first hour's growth is already accounted for in the initial number.
Therefore, the equation y = 68 * 1.5^(x-1) accurately represents the number of people at the fair x hours after opening.
Complete question:
When the county fair opened its gates, 68 people entered the fairgrounds. After one hour, there were 1.5 times as many people on the fairgrounds as when the gates opened. After two hours, there were 1.5 times as many people on the fairgrounds as the previous hour. If this pattern continues, write the equation representing the number of people, y, at the fair x hours after the gates open.
The longer leg of a right triangle is 4cm longer than the shorter leg the hypotenuse is 8 cm longer than the shorter find the side lengths of the triangle
The side lengths of the triangle are 8 cm, 12 cm, and 16 cm
To solve for the side lengths of the right triangle, we can use the Pythagorean Theorem, which states that for any right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Mathematically, this is written as a^2 + b^2 = c^2.
Let's denote the shorter leg of the triangle as x. Then, according to the problem, the longer leg is x + 4 cm and the hypotenuse is x + 8 cm. Plugging these expressions into the Pythagorean Theorem, we have:
x^2 + (x + 4)^2 = (x + 8)^2
Expanding and simplifying the equation:
x2 + x2 + 8x + 16 = x2 + 16x + 64
2x2 + 8x + 16 = x2 + 16x + 64
x2 - 8x - 48 = 0
Solving this quadratic equation for x, we find:
x = 8 cm (shorter leg)
x + 4 = 12 cm (longer leg)
x + 8 = 16 cm (hypotenuse)
Therefore, the side lengths of the triangle are 8 cm, 12 cm, and 16 cm
