1) If the Circumference is 36 then we can find the radius.
\(\begin{gathered} C=2\pi R \\ 36=2\pi R \\ \frac{36}{2\pi}=\frac{2\pi\cdot R}{{2\pi}}\frac{}{} \\ R=\frac{18}{\pi} \end{gathered}\)2) Now we can find the length of that arc AC, using this formula and plugging the radius:
\(\begin{gathered} l=\frac{\alpha}{360}\cdot2\pi\cdot r \\ l=\frac{90}{360}\cdot2\pi\cdot\frac{18}{\pi} \\ l=\frac{1}{4}\cdot36 \\ l=9 \end{gathered}\)3) Hence, the length of that arc AC is 9 units

y-intercept
---
Answer:
\(y=\frac{1}{3}x-4\)
Step-by-step explanation:
Equation of line with points given =
y = mx + b
m = ? , x = 3 , y = -3, b = -4
Therefore, we substitute the value for the given equation
-3 = m * 3 + (-4)
-3 = 3m - 4
-3+4 = 3m
3m = 1
m = 1/3
Therefore we substitute the value for m and b to the equation of line
y = 1/3x - 4
2x+7x=77
5x+7y=115
solve for x & y that makes both expressions true.
The solution that makes both expressions true is x = 8.55556 and y = 10.31746.
To solve for x and y, we need to use a system of equations involves finding the values of x and y that satisfy both equations simultaneously.
We can start by using the first equation to solve for x:
2x + 7x = 77
Combining like terms:
9x = 77
Dividing both sides by 9:
x = 8.55556 (rounded to six decimal places)
Now that we know the value of x we can use either equation to solve for y. Let's use the second equation:
5x + 7y = 115
Substituting x = 8.55556:
5(8.55556) + 7y = 115
Simplifying:
42.7778 + 7y = 115
Subtracting 42.7778 from both sides:
7y = 72.2222
Dividing both sides by 7:
y = 10.31746 (rounded to six decimal places)

John has a savings account that pays him a compounded interest rate of 10%. The interest rate is compounded monthly. His starting principal is $1,604.00. What is his second month's interest?
John's second month's interest, given his starting principal and the interest rate, is $13.48
How to find the second interest?First, find the monthly interest rate as the savings account is compounded monthly:
= 10% / 12 months per year
= 10/12 %
The amount after the first month would be:
= 1, 604 x ( 1 + 10/12%)
= $1, 617.37
The second month's interest to John is therefore:
= 1, 617. 37 x 10/12%
= $13.48
In conclusion, in the second month of his savings investment, John would make an interest of $13.48.

In the given figure, the measure of the central angle CAD is 80°, the major arc is arc CBD, and minor arc is arc CD. The measure of arc BEC is 2.27r and that of arc BC is 0.87r.
About the Central Angle:
An angle formed by two radii of a circle is known as a central angle. Thus, arc BC and arc CD both subtends central angles at the center.
Since BD is the diameter of the circle,
∠BAC + CAD = 180°
It is given that ∠BAC = 100°
⇒ ∠CAD = 180° - 100°
⇒ ∠CAD = 80°
About Major Arc:
The arc which subtends an angle greater than 180° at the center, is called a major arc.
Angle subtended by arc BEC = 360° - m(arc CD)
= 360° - 80°
= 280° > 180°
∴ Arc BEC is the major arc
About Minor Arc:
The arc which subtends an angle less than 180° at the center, is called a minor arc.
⇒ Arc CD is the minor arc.
Calculating arc BEC and arc BC:
Let us assume the radius of the circle is r.
Then, the formula of the measure of an arc is given by,
θ × (π/180) × r
Here, θ is the angle ( in degrees) subtended by the arc at the center.
Arc BEC = 260 × (π/180)r ......... [Put π = 3.14]
= 2.27r
Similarly, arc BC = 100 ×(π/180) × r .......... [Put π = 3.14]
= 0.87r

A volunteer group picked up 3 times as many plastic bottles as cans in their community. The number of papers they picked up was 15 more than 14 of the number of cans. If the volunteers picked up 288 cans, how many more plastic bottles than papers did they pick up?
Answer:
Pls read the whole thing so you can understand how i solved it (PS it's not actually that hard)
Step-by-step explanation:
Ok so I suck at word problems loll but we just have to dissect the equation piece by piece to understand it. So, let's separate the word problem into groups:
A volunteer group picked up 3 times as many plastic bottles as cans in their community.
3(plastic bottles) x ____(cans)
The number of papers they picked up was 15 more than 14 of the number of cans. (*P.S. More than means add)
15 + 14 (more than cans)
If the volunteers picked up 288 cans, how many more plastic bottles than papers did they pick up?
288 cans
Okay, now that we know how many cans we have, we can solve the equation. First,
3(pb) • 288(c) = 864 (plastic bottles)
Second,
15 + 14 = 29 (*So, 29 more papers than cans were picked up)
Third(and final -phew),
How many more plastic bottles than papers? Okay, don't freak out- this is just a two-step solution.
There were 29 more papers than cans picked up, and how many cans were picked up? 288.
288 + 29 = 317 (*That means 317 papers were picked up)
We already solved how many plastic bottles were picked up, so we're almost done. 864 plastic bottles were picked up, remember?
864(pb) - 317(p) = 547
And so, your answer issssss *drumrolls*
547 more plastic bottles than papers were picked up!

Dayson is covering a package in the shape of a rectangular prism with wrapping paper. The package is 50 centimeters by 20 centimeters by 18 centimeters. He has 1 square meter of wrapping paper. Can he completely cover the package with wrapping paper? Complete the explanation to show your answer.
Answer:
Yes, Dayson can completely cover the package with wrapping paper.
Step-by-step explanation:
Given: The rectangular prism is 50 centimeters by 20 centimeters by 18 centimeters.
Area of wrapping paper is 1 square meter.
To find: whether he can completely cover the package with wrapping paper
Solution:
Total surface area of the rectangular prism = 2(lb + bh +hl)
where l denotes length, b denotes breadth and h denotes height
Total surface area of the rectangular prism = \(2\left [ (50)(20)+(20)(18)+(18)(50) \right ]\)
\(=2\left ( 1000+360+900 \right )\\=2(2260)\\=4520\,\,cm^2\)
As \(1\,m^2=10000\,cm^2\),
Total surface area of the rectangular prism = \(4520\,cm^2=0.4520\,m^2\)
As Dayson has \(1\,m^2> 0.4520\,m^2\) of wrapping paper, he can completely cover the package with wrapping paper.
A store sells laptops for $720 each. This price is 20 percent more than what it cost the store to buy each of them. Before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost. How much would it cost an employee to purchase one of these laptops at the sale? PLS HELP
It would cost an employee $443.52 to purchase one of these laptops at the sale.
The selling price of the laptops is $720 each. The cost price is 20 percent more than the cost price.
Cost price = Selling price - 20% of cost price
Cost price = 720 - 20% * 720 = $576
At the release, the laptops are at 23% off the store's cost. Hence:
Price of laptop at release = 576 - 23% of 576
Price of laptop at release = $443.52
It would cost an employee $443.52 to purchase one of these laptops at the sale.

The two points of tangency are (-1,3) and (1,-3).
What is the equation of a tangent to the circle?
The equation of a tangent to a circle is a linear equation that describes a line that touches the circle at exactly one point, without crossing it. A tangent line is perpendicular to the radius of the circle at the point of contact.
Since the line T is tangent to the circle, the radius of the circle drawn to the point of tangency (-1,3) is perpendicular to the line T. Therefore, the center of the circle must lie on the line perpendicular to T at (-1,3).
The equation of the tangent line T can be found by taking the derivative of the equation of the circle and evaluating it at the point of tangency (-1,3):
2x + 2y(dy/dx) = 0
dy/dx = -x/y
At the point (-1,3), dy/dx = -(-1)/3 = 1/3. Therefore, the equation of the tangent line T is:
y - 3 = (1/3)(x + 1)
y = (1/3)x + 10/3
The slope of any line perpendicular to T is -3 (the negative reciprocal of 1/3). The point-slope form of the equation of a line with slope -3 passing through (-1,3) is:
y - 3 = -3(x + 1)
y = -3x
To find the points of tangency, we need to solve the system of equations consisting of the equation of the circle and the equation of the tangent line:
x² + y² = 10
y = -3x
Substituting y = -3x into the first equation, we get:
x² + (9x²) = 10
10x² = 10
x² = 1
x = ±1
Substituting these values of x into y = -3x, we get:
(-1,3) and (1,-3)
Therefore, the two points of tangency are (-1,3) and (1,-3).
