If the circumference of one of the world's largest pizzas is 215 feet, what is its radius? Use 3.14 to approximate pi. Round to the nearest tenth.
Final answer:
The radius of the world's largest pizza with a circumference of 215 feet, using an approximation for pi of 3.14, is approximately 34.2 feet when rounded to the nearest tenth.
Explanation:
To find the radius of the world's largest pizza given its circumference of 215 feet, we use the formula for the circumference of a circle: C = 2πr, where C is the circumference, π (pi) is approximately 3.14, and r is the radius. We rearrange this formula to solve for the radius: r = C / (2π).
Substituting the given values into this equation, we get:
r = 215 feet / (2 × 3.14)
r = 215 / 6.28
r = 34.2356688 feet
Rounding to the nearest tenth gives us:
r ≈ 34.2 feet

Charlie bought 2 1/2 pound bag of oranges for $3.75. What is the cost of one pound of oranges
the distance from town a to town b is 5 miles and the distance from town b to town c is 4 miles. which of the following could Not be the distance, in mile from town a to town c.
A. 1
B. 4
C. 8
D. 9
E. 10
The Triangle Inequality Theorem dictates that the impossible distance from town A to town C, given the distances from A to B (5 miles) and B to C (4 miles), is (E) 10 miles because it exceeds the sum of the other two sides.
The question pertains to the Triangle Inequality Theorem, which in the context given, states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. Here we have two sides measured as 5 miles (from town A to town B) and 4 miles (from town B to town C).
To identify which distance could not be from town A to town C, we recognize that the third side must be less than the sum of the other two sides (5 miles + 4 miles = 9 miles), but also greater than the absolute difference between those two sides (5 miles - 4 miles = 1 mile). Therefore, the only impossible distance for the third side, based on the options provided, is 10 miles, as it exceeds the sum of the other two sides.
Options A (1 mile), B (4 miles), C (8 miles), and D (9 miles) all satisfy the Triangle Inequality Theorem and could represent the distance from town A to town C. Hence, the answer is E (10 miles).
The ground temperature at an airport was 10 degree temperature dropped 5 degrees for every 1000m above the ground. What was the temperature outside an airport that took off from this airport and climbed to 5000m?
PLZ EXPLAIN ANSWER IN DETAIL
The temperature at 5000m is -15 degrees Celsius.
To determine the temperature outside an airplane that has climbed to an altitude of 5000m, we start with the initial ground temperature at the airport, which is 10 degrees Celsius. For every 1000m increase in altitude, the temperature drops by 5 degrees Celsius. We can calculate the temperature decrease over 5000m by multiplying the temperature change per 1000m (5 degrees) by the number of 1000m segments in 5000m (which is 5).
The calculation is as follows:
Temperature drop per 1000m = 5 degrees Celsius
Number of 1000m segments in 5000m = 5
Total temperature drop = 5 segments * 5 degrees/segment = 25 degrees Celsius
Temperature at 5000m = Ground temperature - Total temperature drop
Temperature at 5000m = 10 degrees Celsius - 25 degrees Celsius
Temperature at 5000m = -15 degrees Celsius
Therefore, the temperature outside an airplane that climbs to an altitude of 5000m is -15 degrees Celsius.
Fatima plans to spend at least $15 and at most $20 dollars on sketch pads and pencils. If she buys 2 sketchpads, how many pemcils can she buy while staying in her price range?

Jessica has 48 sticker.This is 8 times as many stickers as Taylor has.How many stickers does Taylor have?
Taylor has 6 stickers, as Jessica's 48 stickers are 8 times Taylor's amount. Also, after certain actions, we can conclude that Jenny initially had 14 chocolates.
Explanation:Jessica has 48 stickers, which is 8 times as many stickers as Taylor has. To find out how many stickers Taylor has, we need to divide the number of Jessica's stickers by 8:
48 stickers \/ 8 = 6 stickersTherefore, Taylor has 6 stickers.
In a similar problem, Jenny has some chocolates. After eating two chocolates and giving half of the remainder to Lisa, Lisa ends up with 6 chocolates. To determine the number of chocolates Jenny started with, we multiply the number Lisa received (6) by 2 and then add the 2 chocolates Jenny ate:
Lisa has 6 chocolates, which is half of what remained after Jenny ate 2, so before giving, Jenny had 6 * 2 = 12 chocolates.Add the 2 chocolates Jenny ate: 12 + 2 = 14 chocolates.Hence, Jenny initially had 14 chocolates.

Is 5 g greater than 508 mg
Yes, 5 grams (5 g) is greater than 508 milligrams (508 mg).
To compare the two quantities, grams (g) and milligrams (mg),
Make sure they are in the same unit.
Since 1 gram is equal to 1000 milligrams, we convert the given values into the same unit, which is milligrams (mg).
5 grams (5 g)
508 milligrams (508 mg)
To compare them, we need to convert 5 grams into milligrams:
5 grams × 1000 milligrams/1 gram = 5000 milligrams
Now, we have both quantities in milligrams:
5 g = 5000 mg
508 mg = 508 mg
Since 5000 mg is greater than 508 mg, we can conclude that 5 grams (5 g) is greater than 508 milligrams (508 mg).
Therefore, 5 grams is indeed greater than 508 milligrams.

Triangle ABC is translated to image A′B′C′. In this translation, A(5, 1) maps to A′(6, –2). The coordinates of B′ are (–1, 0). The coordinates of B are (-2, 3). How?
Answer:
B (-2, 3)
Step-by-step explanation:
Just took quiz
The coordinates of B before translated to B' are (-2,3).
Translation is a term used in geometry to describe a function that moves an object a certain distance.
In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system.
In translation, only the position of the object changes, its size remains the same.
For the given situation,
Triangle ABC is translated to image A’B’C’.
In this translation, A(5, 1) maps to A’(6,-2).
In translation, the distance between A' and A in the coordinate system is same as B'B and C'C.
Let A(x_1,y_1) = (5,1) and A'(x_2,y_2) = (6,-2)
⇒ x_1 - x_2 = 5 -6
⇒ -1
⇒ y_1 - y_2 = 1- (-2)
⇒ 3
The coordinates of B’(-1,0)
So, the coordinates of B is
⇒ x= (-1 -1) = -2
⇒ y= (0 + 3) =3
Thus coordinates of B are (-2,3).
Hence we can conclude that the coordinates of B before translation are (-2,3).

A train leaves a station at 10:40 a.m. and arrives at its destination at 1:20 p.m. Find the distance between the stations if the average speed of the train was 60 mph.
160 miles.
10:40-11:40 is 60 min., which is 60 miles
11:40-12:40 is 60 min., which is also 60 miles
12:40-1:00 is 20 min. = 20 miles
1:00-1:20 is 20 min. = 20 miles
60+60+20+20 = 160 miles
Answer:
The answer is 160.2 miles.
Step-by-step explanation:
In order to determine the distance, we have to know the total time that train traveled. We know that the train leaves at 10:40 a.m. and arrives at 1:20 p.m.
So,
10:40 a.m. to 11:00 a.m.=20 minutes
11:00 a.m. to 1:00 p.m.=120 minutes
1:00 p.m. to 1:20 p.m.=20 minutes
Then, the total time is 20+120+20=160 minutes. Also we have to know that the speed is the rate of distance per time. The units are miles per hours, thus 160 min=2.67 hours.
S=speed of the train.
D=distance of the train.
T=total time of the train.
[tex]S=\frac{D}{T}\\60=\frac{D}{2.67}\\D=60*2.67\\D=160.2[/tex]
Finally, the distance between the stations is 160.2 miles.

explain the difference between a linear equation in one variable and a linear equation in two variables. Give an example of each.
Final answer:
The difference between a linear equation in one variable and in two variables lies in the number of variables and their graphical representation: a linear equation in one variable like 'x + 5 = 0' represents a point on the x-axis, while a linear equation in two variables like 'y = 2x + 3' represents a straight line on a plane.
Explanation:
Difference between a Linear Equation in One Variable and Two Variables
The main difference between a linear equation in one variable and a linear equation in two variables is the number of variables involved and how they can be graphically represented. A linear equation with one variable can be written in the form ax + b = 0, where a and b are constants, and x is the variable. This equation represents a single straight line in a two-dimensional space, where all points on the line have the same x-coordinate. For example, x + 5 = 0 is the equation of a vertical line represented by the point where x is -5.
On the other hand, a linear equation in two variables typically has the form y = mx + b, which represents a line in two-dimensional space where m is the slope of the line and b is the y-intercept. Here, x is the independent variable and y is the dependent variable. As x changes, y changes in a way that the relationship between them remains constant, making the graph a straight line. For example, y = 2x + 3 is an equation of a line with a slope of 2 and a y-intercept of 3.
When comparing the two types of equations, it's clear that linear equations in two variables can represent a broader range of relationships between two quantities, allowing for a visual representation of the relationship as a slope on a graph.
