Isaac is also designing a circular serving tray that he plans to engrave around the edge. The serving tray has an area of 3.14 square feet. Using 3.14 for , what is the circumference of the serving tray rounded to the nearest hundredth?
Answer:
6.28 feet
Step-by-step explanation:
1.) Find the radius.
The area is given, and the formula for area of a circle is A = [tex]\pi r^{2}[/tex] Let's substitute.
3.14 = [tex]\pi r^{2}[/tex]
Divide by pi on both sides
1 = [tex]r^{2}[/tex]
Find the square root of r
1 = r
The radius is 1.
2.) Find the circumference.
C = [tex]2\pi r[/tex]
C = [tex]2\pi (1)[/tex]
Multiply 2 and 1
C = [tex]2\pi[/tex]
C ≈ 6.28
The circumference is approximately 6.28 feet.
Final answer:
To find the circumference of a circular serving tray with an area of 3.14 square feet, one must first calculate the radius using the area formula and then apply the circumference formula 2πr, yielding a circumference of 6.28 feet when rounded to the nearest hundredth.
Explanation:
In order to find the circumference of Isaac's circular serving tray given its area, we need to apply the formula for the area of a circle, which is A =
^2. Since the area was provided as 3.14 square feet, and using 3.14 as an approximation for
, we can set up the equation as 3.14 = 3.14r^2. This allows us to solve for the radius(r).
First, divide both sides by 3.14 to isolate r^2: r^2 = 3.14 / 3.14 = 1. Then take the square root of both sides to get the radius: r =
1 = 1 foot. Now that we have the radius, we can calculate the circumference using the formula C = 2
, substituting 3.14 for
, and the radius we just found: C = 2 * 3.14 * 1 = 6.28 feet.
After following these steps, we determine that the circumference of the serving tray is 6.28 feet. Rounded to the nearest hundredth, the circumference is 6.28 feet.

A plumber charges a one-time fee of $75 plus a fixed hourly rate, h, in dollars. The plumber works at a customer’s house for 2 hours and charges a total of $205.
Part A
Which tape diagram represents this situation?
A
B
C
D
Answer:
$65/hour
Step-by-step explanation:
Let C(h) represent the total amount payable to the plumber. Then:
C(h) = $75 + (rate)(2 hr) = $205. Solve for the "fixed hourly rate."
Subtracting $75 from both sides, we get:
(rate)(2 hr) = $130.
Dividing both sides by (2 hr) results in (rate) = $65/hour
The total bill of $205 is composed of a $75 fixed charge and $130 for the 2 hours worked. This implies that the plumber charges an hourly rate of $65. A representative tape diagram would show these components separately, with 2 equal blocks for the hourly rate totaling to the overall cost of $205.
Explanation:The situation described is a basic arithmetic problem dealing with a fixed cost ($75) and a variable cost (hourly rate, represented as h). The equation that represents this problem is 75+2h=205, derived from the fixed cost plus two times the hourly rate (since the plumber worked for 2 hours). To solve for h (the hourly rate), we subtract 75 from both sides which leaves us with 2h=130, then divide by 2, giving us h=65. This means the hourly rate, h, the plumber charges is $65.
Without seeing the options A, B, C, and D, I can't explicitly say which tape diagram would best represent this situation. However, ideally, the tape diagram should illustrate $75 as a fixed cost and then two equal blocks (each equivalent to $65) to represent the cost of each hour worked. The total of all blocks combined should equal $205, the total cost.

How many obtuse angles are in an obtuse triangle
Answer:
ONE
Step-by-step explanation:
Only one. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
Answer: ONE
The required, an obtuse triangle is a triangle that has one angle measuring more than 90 degrees. By definition, an obtuse triangle has exactly one obtuse angle.
An obtuse triangle, by definition, contains one obtuse angle, which is an angle greater than 90 degrees but less than 180 degrees. The obtuse angle is the largest angle in an obtuse triangle, while the other two angles are acute angles (less than 90 degrees).
Since there is only one angle in an obtuse triangle that qualifies as an obtuse angle, we can conclude that there is exactly one obtuse angle in an obtuse triangle. The remaining two angles are acute angles.
It's important to note that the sum of the angles in any triangle is always 180 degrees. In the case of an obtuse triangle, the obtuse angle occupies a portion of that sum greater than 90 degrees, leaving the remaining acute angles to share the remaining portion of the 180-degree total.

The scale of a map is 3 in: 45mi. Find the actual distance if the map distance between two towns is 5 in.
Answer:
75 miles
Step-by-step explanation:
We can use cross products to solve
3 in 5 in
--------------- = -------------------
45 mi x miles
3 * x = 5 * 45
3x = 225
Divide each side by 3
3x/3 = 225/3
x =75 miles
To find the actual distance between two towns on a map, use the scale provided. Set up a proportion using the scale and the map distance to find the actual distance. In this case, the actual distance is 75 miles.
Explanation:To find the actual distance between two towns on a map, you can use the scale provided. In this case, the scale is 3 in: 45 mi. This means that 3 inches on the map represents 45 miles in the real world. If the map distance between the two towns is 5 inches, you can set up a proportion to find the actual distance.
Using the scale, you can set up the equation:
3 inches / 45 miles = 5 inches / x miles
Cross-multiplying, you get:
3 * x = 5 * 45
Simplifying, you get:
x = (5 * 45) / 3
x = 75 miles
Therefore, the actual distance between the two towns is 75 miles.

belle put the muffins she baked on six plates, four of which are red and two of which are yellow. the four red plates each have 5 muffins. the two yellow plates each have the same number of muffins write an expersion for the total number of muffins belle baked if each yellow plate has 8 muffins,find how many muffins belle baked in all
Answer:
36 total muffins
Step-by-step explanation:
5*4=20
8*2=16
20+16=36
Hey there!
To write an expression to represent this:
We know that the four red plates each have 5 muffins, and 4 x 5 = 20.
So we can say 20 + 2y is the expression, because we add 20 to the muffins on the two yellow plates.
The number of muffins on each yellow plate is represented by the variable y.
If each yellow plate has 8 muffins, so y = 8, the expression will look like this:
20 + 2(8)
Multiply 2 x 8.
20 + 16
Add 20 + 16.
36
Belle baked 36 muffins total.
