The area of a circle is 49π cm^2. Find the circumference of the circle. Leave your answer in exact form, no decimals, and include units (Note: make sure you are showing the formulas you use to answer the question and how the numbers fit into the formulas).
Step-by-step explanation:
Let r be the radius of the circle
The area of a circle is A = pi * r^2
We know the area is 49 pi
pi r^2=49 pi
r^2=49 pi/pi
r^2=49
r=sqrt 49
r=7
The circumference of the circle is calculated as
C = 2pi*r
C = 2 *pi *(7)
C = 14*pi cm
pi=22/7
C=14*22/7=2.22=44 inches
so,C =44 inches
The cost to produce x units of wire is C= 55x + 450, while the revenue is R= 80x. Find all intervals where the product will at least break even.
The product will break even when x is greater than or equal to 18 units, i.e., x ≥ 18, as revenue (R) exceeds or equals cost (C) at this production level.
To find the intervals where the product will at least break even, we need to determine the values of x for which the revenue (R) is equal to or greater than the cost (C), i.e., R ≥ C.
Given:
Cost function C(x) = 55x + 450
Revenue function R(x) = 80x
We can set up the inequality:
80x ≥ 55x + 450
To isolate x, we can subtract 55x from both sides:
80x - 55x ≥ 55x - 55x + 450
This simplifies to:
25x ≥ 450
Now, divide both sides by 25 to solve for x:
x ≥ 450 / 25
x ≥ 18
So, the product will break even when x is greater than or equal to 18. This means that for any production level of 18 units or more, the revenue will be equal to or greater than the cost, ensuring that the product is at least breaking even. Therefore, the interval where the product will at least break even is x ≥ 18.

To break even, the revenue (R) must equal the cost (C). Setting the revenue function R = 80x equal to the cost function C = 55x + 450 and solving for x, we find that the product will break even when x >= 18 units, meaning the company will begin to make a profit at any production level greater than 18 units.
To find where the product will at least break even, we need to determine when the total revenue
(R) is greater than or equal to the total cost (C). The cost to produce
x units of wire is given by C = 55x + 450, and the revenue by R = 80x. To break even,
R must be equal to C:
80x = 55x + 450
Solving for x gives us:
80x - 55x = 450
25x = 450
x = 450 / 25
x = 18
Therefore, the product will break even at x = 18 units. For any number x greater than 18, R will be greater than C, which means profits are being made. The interval for breaking even is thus x >= 18.

Step-by-step explanation:
The coordinates are the pair (x,y) in the axis. We already have three vertexs: a: (x,y)=(2,3); b:(x,y)= (7,3) and c: (x,y)=(7,-2).If you see the picture attached, where all points available are in pink, you will see that the distance between the sides that are already defined equals 5. Because all squares have equals sides, then we must find the missing side that will be at a distance of 5 between the other two vertexs.That point is d (x,y)=(2,-2).Type the correct answer in each box.

Kiki has $2.48 in her change purse and $1.69 in her hand. Jordan has $3.05 in his left pocket and $1.09 in his right pocket. Who has more money, and how much more money does that person have? Write your answer in a complete sentence.
Answer:
Kiki has 0.03 cents more than Jordan.
Step-by-step explanation:
so first add 2.48 and 1.69= 4.17
Kiki's amount of money= $4.17
Add 3.05 and 1.09= 4.14
Jordan's amount of money= $4.14
subtract 4.17-4.14=0.03
After adding up the amounts for both Kiki and Jordan, it is determined that Kiki has more money by $0.03.
Explanation:To find out who has more money, Kiki or Jordan, we need to add up the amounts that each person has in their respective locations and then compare the totals. First, let's calculate Kiki's total amount:
Kiki's change purse: $2.48Kiki's hand: $1.69Adding these two amounts gives Kiki a total of $4.17.
Now let's calculate Jordan's total amount:
Jordan's left pocket: $3.05Jordan's right pocket: $1.09Adding these two amounts gives Jordan a total of $4.14.
By comparing the two totals, we see that Kiki has more money than Jordan. The difference in their amounts is $4.17 (Kiki's total) - $4.14 (Jordan's total) = $0.03. Therefore, Kiki has three cents more than Jordan.
In a complete sentence: Kiki has more money than Jordan by three cents.
how many children are in a crowd of 7900 if the proportion is 20%?
Answer:
7900/100*80 = 6320
Step-by-step explanation:
In a crowd of 7,900, there are 1,580 children, representing 20% of the total population.
To find out how many children are in a crowd of 7,900 when the proportion is 20%, you can use the following steps:
1. Calculate the proportion (20%) as a decimal: 20% = 0.20.
2. Multiply the crowd size (7,900) by the proportion (0.20) to find the number of children:
Children = 7,900 * 0.20 = 1,580.
So, in a crowd of 7,900, there are 1,580 children.
This calculation is based on the assumption that the 20% proportion represents the fraction of the crowd that consists of children. If you have additional information about the crowd's composition or the nature of the 20%, such as whether it includes adults or other groups, the calculation may differ.

What is the measure of the supplement of the angle 90
Answer:
90°
Step-by-step explanation:
supplementary angles, when added = 180°
so if one angle is 90°, then the other angle, its supplement, is 180 - 90 = 90°
Answer:
90°
Step-by-step explanation:
The supplement of an angle is what, when added to it, equals 180°.
So if we have 90°, we would subtract 90° from 180° to get 90°.
The supplement of 90° is 90°.
The complement of 85° is 5°, since they add up to equal 90° a right angle. So the complement of 90° is 0°

Find the constant variation when t varies directly as the square root of s, and t=64 when s=4
Answer:
a or b
Step-by-step explanation:
Final answer:
The constant of variation k is found by substituting the given values into the direct variation equation t = k√s and solving for k, leading to the result k = 32.
Explanation:
We are given that t varies directly as the square root of s, which can be represented as t = k√s, where k is the constant of variation. To find k, we use the provided values: t=64 when s=4. Substituting these values into the equation gives us:
64 = k√4
Since the square root of 4 is 2, we get:
64 = 2k
Dividing both sides by 2, we find that k = 32, which is the constant of variation.

The correct answer is [tex]$\sqrt{3}$[/tex]. Hence the correct option is d.
To find the value of [tex]$\tan 60^\circ$[/tex] using the unit circle, follow these steps:
Draw the unit circle, which is a circle with a radius of 1 unit centered at the origin (0,0) on the Cartesian coordinate plane.
Identify the point on the unit circle corresponding to [tex]$60^\circ$[/tex]. This point is located in the first quadrant and makes an angle of [tex]$60^\circ$[/tex]with the positive x-axis.
Since the unit circle has a radius of 1, the coordinates of the point corresponding to 60 are:
[tex]$x$-coordinate: $\cos(60^\circ) = \frac{1}{2}$\\$y$-coordinate: $\sin(60^\circ) = \frac{\sqrt{3}}{2}$[/tex]
Now, we'll use the definition of tangent to find [tex]$\tan(60^\circ)$[/tex]:
[tex]$\tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)}$\\Substitute the values of $\sin(60^\circ)$ and $\cos(60^\circ)$ into the formula:$\tan(60^\circ) = \frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}$[/tex]
Simplify the expression:
[tex]$\tan(60^\circ) = \left(\frac{\sqrt{3}}{2}\right) \cdot \left(\frac{2}{1}\right)$$\tan(60^\circ) = \sqrt{3}$[/tex]
So, the correct answer is [tex]$\sqrt{3}$[/tex]. Hence the correct option is d.
