Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Bud’s cheeseburger and fries contained 1310 milligrams and 350 milligrams of sodium, respectively. Together they contained 66.4% of the recommended daily intake of sodium for a 2,000 calorie diet. What is the daily recommended intake of sodium for a 2,000 calorie diet? Show your work.
Answers
The daily recommended intake of sodium for a 2,000 calorie diet is 2000 calorie diet is 2500 mg.
What is diet?Healthy diet:
A healthy diet helps protect against malnutrition in all its forms and is a foundation for health and development. It also helps to prevent noncommunicable diseases including diabetes, cardiovascular diseases, some cancers and other conditions linked to obesity.
In order to calculate the daily intake of sodium we first need to calculate the mass of sodium present in both snacks, this is given by their sum.
\(\text{Total sodium = 1310 + 350 = 1660}\)
We can now apply a rule of three for which the total sodium from the snacks is related to 66.4% in the same proportion as "x" mg, which is the value we want to know, is related to 100%. So we have:
\(\frac{1660}{x} \frac{mg}{mg} = \frac{66.4}{100} \\\\66.4*x = 1660*100\\x=\frac{166000}{66.4} = \bold{2500\text{ mg}}\)
Hence, the daily recommended intake of sodium for a 2,000 calorie diet is 2000 calorie diet is 2500 mg.

The volume of a cone is 80π cubic units. The radius of this cone is tripled.
Eric says the new volume will be tripled. It is 240π cubic units.
Natalie says the new volume will be multiplied by 9. It is 720π cubic units.
Who is correct? Explain your reasoning.
Answers
V = (1/3)πr^2h
Where V is the volume, r is the radius, and h is the height. If the radius of a cone is tripled, the volume of the cone will be multiplied by 9. This is because the radius is squared in the formula, so tripling the radius is the same as multiplying it by 3*3=9.
To see this more clearly, consider the following example:
Suppose the radius of a cone is 2 units and the height is 4 units. The volume of the cone is:
V = (1/3)π(2^2)(4) = (1/3)π(4)(4) = (1/3)π(16) = 16π/3 cubic units
If we triple the radius of the cone to 6 units, the volume of the cone becomes:
V = (1/3)π(6^2)(4) = (1/3)π(36)(4) = (1/3)π(144) = 144π/3 cubic units
The volume of the cone has been multiplied by 9.

Answer: 66 yd
Explanation: It might seem like a very difficult shape to find the area, but it is actually really simple. All you have to do is split this shape in multiple squares, then find each area of each square, then add up all the square's area to get the total area of the shape.
Notice: Please take a look at the image I included to see how I divided the shape.
Step 1.) Since the shape is in a weird shape that doesn't allow us to find the area by normal means, we will split it in workable shapes. In this case, splitting it in 3 rectangles is best option (see image below).
Step 2.) Find the dimensions of each rectangle you split. Since we have new shapes, let us find the dimensions of each shape now.
Notice: Some sides of the shapes are split in half, to find the total length of a side we just add up the splits of the side. In this example our length's of the Rectangle 1 and 3 where split by 2 and 5 yards.
Rectangle 1: Length: 7yd; Width: 4yd
Rectangle 2: Length: 2yd; Width: 5yd
Rectangle 3: Length: 7yd; Width: 4yd
Step 3.) With the new dimensions of each shape, apply the correct formula for the area of each rectangle to find the area of each rectangle.
Area = Length x Width
A= L x W
Rectangle 1: Area = 28
A = L x W
A = (7) x (4)
A = 28
Rectangle 2: Area = 10
A = L x W
A = (2) x (5)
A = 10
Rectangle 3: Area = 28
A = L x W
A = (7) x (4)
A = 28
Final Step 4.) Now that we have the area of each individual rectangle, let us combine all the areas to find the total area of the shape.
Rectangle 1 + Rectangle 2 + Rectangle 3 = 66
28+10+28 = 66
Note: If you have any questions please let me know. If not, I hope this helped. Your very welcome :-)

A local jewelry store sells class rings, which it purchases for $60 each. The store engraves a name and date on the ring and sells it using a markup rate of 340%.
What is the markup rate in decimal form?
The markup rate is the constant of proportionality in the equation y=kx
. Write an equation that can be used to find the markup on the cost x
of a ring.
Use the equation to find the markup amount by substituting the cost of a ring for x
.What is the retail price of a ring?
During graduation week, the store is going to reduce the price to $184.80.
Calculate what percent the sale price is of the retail price.
Think of the retail price of the ring as 100%. How does the sale price compare to the retail price? What does this tell you about the markdown rate?
What is an equation in the form y=kx
that relates the sale price to the retail price x
?
Answers
The equation that can be used to find the markup on the cost x of a ring is: Markup = 3.40x.
If the store purchases the rings for $60 each, the markup amount would be:
Markup = 3.40 x $60 = $204
The retail price of a ring would be the cost plus the markup amount:
Retail price = Cost + Markup = $60 + $204 = $264
During graduation week, the store is reducing the price to $184.80. To find what percent the sale price is of the retail price:
Sale price percentage = (Sale price / Retail price) x 100%
Sale price percentage = ($184.80 / $264) x 100% = 70%
The sale price is 70% of the retail price. This means that the markdown rate is 30%.
An equation in the form y=kx that relates the sale price to the retail price x is:
Sale price = k x Retail price
To find k, we can use the information given in the problem that the sale price is 70% of the retail price:
0.70 Retail price = k x Retail price
Simplifying this equation, we get:
k = 0.70
Therefore, the equation in the form y=kx that relates the sale price to the retail price x is:
Sale price = 0.70 x Retail price

b) No. bumpy yellow pea pods = 87
No. of smooth yellow pea pods = 261
No. of bumpy green pea pods = 261
No. of smooth green pea pods = 783
Ratio of bumpy yellow to smooth yellow to bumpy green to smooth green pea pods = 87/261/261/783
= 1/3/3/9
= 1:3:3:9
