Answer: Ruth have to make 7 hats to break even.
Step-by-step explanation:
Break even point is a point where Cost = Revenue.
Let x be the number of hats sold.
Given: Cost of booth = $63
Each hat cost = $10
Selling price for each cost = $19
As per given,
Total cost = Cost of booth+ (Cost of each hat)(Number of hats)
= 63+10x
Total selling price = 19x
For break even,
63+10x=19x
9x=63
x=7
Hence, Ruth have to make 7 hats to break even.
the area of a circle is 100 square miles. What is the diameter?
Answer:
The diameter of a circle with an area of 100 square miles is 20/√π miles.
Step-by-step explanation:
Area =100 = πr^2.
diameter = d = 2r.
100 = πr^2.
100/π = r^2.
√(100/π) = r.
10/√π = r.
d = 2r.
d = 2 * 10/√π.
d = 20/√π
Luigi decided to grab lunch at Howell's Cafe with his friends. The bill for their meals was the $36.50. The restaurant charges a 7% tax. How much is the total bill?
Answer:
$39.055
Step-by-step explanation:
100% + 7% = 107%
[tex]\frac{y}{36.5} :\frac{107}{100}[/tex]
y · 100 = 107 · 36.5
100y = 3905.5
100y ÷ 100 = 3905.5 ÷ 100
y = 39.055

Mr. Peterson graded 117 tests in 3 hours. How many tests can he grade in 5 hours?
Answer:
195
Step-by-step explanation:
create a proportion: # tests/time = # tests/time
let 't' = # tests graded
117/3 = t/5
cross-multiply to get:
3t = 585
t = 585/3 which equals 195

Use the Pythagorean Theorem.
a2+2304=a^{2}+2304=a2+2304=

Subtract 2304 from both sides.
a2=a^{2}=a2=

a2=\sqrt{a^{2}}=a2
=
±196\,\,\pm\sqrt{196}±196
Square root both sides.
a=a=a=

Simplify. Ignore negative root, as length must be positive.
what is the perimeter of triangle KLM? i was only given one side and then 60° and 30°
please help this makes no sense
Answer:
[tex]18+6\sqrt{3}[/tex]
Step-by-step explanation:
In all 30-60-90 triangles, the side lengths are in the ratio [tex]x:x\sqrt{3}:2x[/tex], where [tex]2x[/tex] is the length of the hypotenuse, or longest side, of the triangle and [tex]x[/tex] is the length of the side that is directly opposite to the 30 degree angle.
The figure consists of three 30-60-90 right triangles (two inside a larger one). The side KL is marked as 6 meters and represents the side opposite to the 30 degree angle of the largest triangle (Since [tex]\angle L=90^{\circ}[/tex] and [tex]\angle K=60^{\circ}[/tex]). Therefore, the hypotenuse (longest side) of the triangle must be [tex]2\cdot 6=12[/tex] and the other leg must be [tex]6\sqrt{3}[/tex].
The perimeter of a polygon is equal to the sum of all the polygon's sides and therefore the perimeter of thing triangle is [tex]6+12+6\sqrt{3}=\boxed{18+6\sqrt{3}}[/tex]

O Linear association
O Non-Linear association
No association
Answer:
Step-by-step explanation:
I'm assuming that non-linear means that there is some type of association between the dots, they are just not in a straight line. Now, they definitely are NOT in a straight line, but they do appear to be falling in an exponential pattern. I would say that this is a non-liner association (exponential decay, to be specific).

A small pyramid has 3 stones at the top and 2 more stones in each
layer below this. If the pyramid has 19 layers, how many stones are in the pyramid?
- Help please ?!
Answer
93
Step-by-step explanation:
There are 399 stones in the pyramid of 19 layers if there are 3 stones at the top and 2 more stones in each layer below this
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A small pyramid has 3 stones at the top and 2 more stones in each layer below this. This can be represented as an arithmetic progression with first term (a) = 3 and difference (d) = 2, hence:
number of stones in 19 layers = [tex]\frac{19}{2}(2(3)+(19-1)2)=399[/tex]

find the unique permutations of the letters of the word : CEASELESS
Answer:
There are 2,520 unique permutations.
Step-by-step explanation:
When we have a set of N different elements, the total number of permutations is given by:
P = N! = N*(N - 1)*(N - 2)*...*(2)*(1)
Particularly, if out of these N elements, there are a given element that is repeated K times, then the permutations of these K elements actually do not add new unique permutations, then in that case the total number of unique permutations is:
P = N!/K!
And if we have another element that is repeated L times, then with the same reasoning than above, the total number of unique permutations is:
P = N!/(K!*L!)
Now, we have the set:
{C, E, A, S, E, L, E, S, S}
So we have a set of 9 letters, then:
N = 9
And, the letter S is repeated 3 times
The letter E is repeated 3 times
Then, using the above notation, we can define:
K = 3
L = 3
The total number of permutations is then:
[tex]P = \frac{9!}{3!*3!} = \frac{9*8*7*6*5*4*3*2*1}{3*2*1*3*2*1} = \frac{9*8*7*6*5*4}{3*2*1} = 2,520[/tex]
So there are 2,520 unique permutations.

Step-by-step explanation:
=> Total amount the 1st year = 90,000
=> Since after the 1st yr, there was a reduction of 4%, so 100% - 4% = 96% or 0.96
=> Total time = 6
We know that the formula of a geometric sequence is;
aₙ = a₁ * r⁽ⁿ⁻¹⁾
In which;
aₙ = the value that has to be figured out (in this case it would be a₆)a₁ = the first term of the sequence (in this case it would be 90,000)r = common ration (in this case it would be 0.96)n = given time (in this case it would be 6)Therefore we can finally say;
=> aₙ = a₁ * r⁽ⁿ⁻¹⁾
=> a₆ = 90,000 * 0.96⁶⁻¹
=> a₆ = 90,000 * 0.96⁵
=> a₆ = 73383.54
=> a₆ = 73384 (Rounded to the nearest whole number)
Therefore, rounding the answer to the nearest whole number, the answer would be; 73384 kilotons

Given y = 3x + 1 State the quadrants in which this graph is in. (Use the numbers 1-4)
The graph of y = 3x + 1 lies in quadrants I and III. The graph of the equation y = 3x + 1 is a straight line with a positive slope.
To determine the quadrants in which the graph lies, we need to analyze the signs of the x and y coordinates in different regions of the coordinate plane.
Quadrant I: In this quadrant, both the x and y coordinates are positive. When we substitute positive values for x into the equation, we obtain positive values for y. Since the slope is positive, the line rises as we move from left to right. Therefore, the graph lies in quadrant I, where both x and y are positive.
Quadrant III: In this quadrant, the x coordinate is negative, while the y coordinate is positive. If we substitute negative values for x into the equation, we still obtain positive values for y. The positive slope ensures that the line rises from right to left. Hence, the graph also lies in quadrant III.
The graph does not pass through quadrants II and IV because the signs of the coordinates do not align with the equation. In quadrant II, the x coordinate is negative, but the y coordinate is negative as well. In quadrant IV, both the x and y coordinates are positive, which contradicts the equation. Therefore, the graph of y = 3x + 1 is confined to quadrants I and III.

Answer:
a = 5
Step-by-step explanation:
According to the factor theorem, if x + 2 is a factor, then by dividing the polynomial by the binomial, we are meant not to have a remainder
In this case, the remainder would be zero
So, if we set the binomial equals zero and substitute the x-value into the polynomial, we are supposed to have 0
So we have this as;
x + 2 = 0
x = -2
-2^3 -2(-2)^2 -2(a) + 6 = 0
-8-8-2a + 6 = 0
-16 + 2a + 6 = 0
2a -10 = 0
2a = 10
a = 10/2
a = 5
