Solve for x and y
5x + y = 9
10x -7y = -18
Answer:
x=1; y=4
Step-by-step explanation:
for this system, you could use either substitution or elimination
i'll solve it both ways
SUBSTITUTION:
5x+y=9 becomes y=-5x+9
10x-7y=-18; substitue y from y=-5x+9
10x-7(-5x+9)=-18
10x+35x-63=-18
45x=45
x=1
substitue x into y=-5x+9
y=-5(1)+9
y=4
ELIMINATION
5x+y=9
10x-7y=-18
multiple the top equation by 7 to get 35x+7y=63
now, 7y and -7y cancel out
add the two equations to get 45x=45

How do you calculate the arc length of a circle?
To calculate the arc length of a circle, you need to use the formula: arc length = (central angle in radians) x (radius)
where the central angle is measured in radians and the radius is the distance from the center of the circle to the edge. To use this formula, first convert the central angle from degrees to radians by multiplying it by π/180. Then, multiply the result by the radius to find the arc length. For example, if you have a circle with a radius of 5 units and a central angle of 45 degrees, you can calculate the arc length as follows: Convert the central angle to radians: 45 x π/180 = 0.7854 radians. Multiply the central angle in radians by the radius: 0.7854 x 5 = 3.927 unit. Therefore, the arc length of a circle with a radius of 5 units and a central angle of 45 degrees is 3.927 units.

Part B
The company decides to keep the radius the same and double the height. Rounded to the nearest hundredth, how many cubic inches is the new volume of the package?
The height of the cylindrical package is 6 inches.
The new volume of the package is 88.26 cubic inches.
What is a cylinder?A cylinder is a 3-D figure that has a radius and a height.
The volume of a cylinder is given as πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume.
= 3.14 x 2 x 2 x 5
= 62.8 cm³
We have,
Part A:
The formula for the volume of a cylinder is V = Bh, where B is the area of the base of the cylinder and h is its height.
For a cylinder with radius r and height h, the base area B is given by
B = πr².
Substituting the given values, we have:
V = Bh
87.92 = π(2²)h
h = 87.92 / (4π)
h ≈ 5.57
Rounding to the nearest inch, the height of the cylindrical package is 6 inches.
Part B:
If the company doubles the height of the cylinder while keeping the radius the same, the new height will be 2h = 2(5.57) = 11.14 inches.
The new volume can be calculated using the same formula:
V = Bh
V = π(2²)(11.14)
V ≈ 88.26 cubic inches
Rounding to the nearest hundredth, the new volume of the package is 88.26 cubic inches.

What is the linear equation represented by the graph?
The linear equation represented by the graph is y = 8x.
Describe Linear equation?A linear equation is a mathematical equation that describes a straight line in a two-dimensional space. It can be written in the form of:
y = mx + b
where y and x are variables, m is the slope of the line, and b is the y-intercept of the line (the point where the line crosses the y-axis).
The slope, represented by "m", describes the steepness of the line, while the y-intercept, represented by "b", is the point where the line intersects with the y-axis.
Linear equations can also be written in other forms, such as the standard form:
Ax + By = C
where A, B, and C are constants, and x and y are variables. In this form, the equation describes a line in terms of its x and y intercepts.
Linear equations are used in a variety of fields, including mathematics, physics, engineering, economics, and more. They are useful for describing and predicting relationships between variables that exhibit a linear pattern.
The equation represented by the graph is a linear equation in the form of y = mx + b, where m is the slope and b is the y-intercept.
To find the slope, we can use the formula:
m = (y2 - y1)/(x2 - x1)
Let's choose the first two points (0.5, 4) and (1, 8):
m = (8 - 4)/(1 - 0.5) = 8
So, the slope is 8.
To find the y-intercept, we can use the point-slope form of the equation:
y - y1 = m(x - x1)
Let's choose the point (0.5, 4) and the slope we just found:
y - 4 = 8(x - 0.5)
y - 4 = 8x - 4
y = 8x
So, the linear equation represented by the graph is y = 8x.

Answer: [tex]370.08 m^2[/tex]
Step-by-step explanation: Lets do the easy part first. We see that there is a proven square in the center of the figure with side lengths of 12. The area formula is [tex]l*w[/tex] and since its a sqaure we can just multiply a side length by itself.
[tex]12*12 = 144[/tex]
^^ Thats the area of the square.
We now have to do the more difficult part which is finding the area of the semi circles. I combined the semi circles to form 2 circles with diameter 12. Now we know that the area of a circle is [tex]\pi r^2[/tex] and that the diameter is [tex]2r[/tex] so we just divide 12 by 2 to get the radius which is 6. Now we use the area formula and multiply it by 2 because there are 2 circles.
[tex]A = 2(3.14)(6^2)[/tex]
which is
[tex]226.08[/tex]
Now add it to the area of the square to get the area of the figure.
[tex]226.08+144 = 370.08[/tex]

The correct response is C. 0.0036 Square degrees The field of vision of the Hubble Space Telescope is only 0.006 degrees, which is around 100 times less than that of the Micro Observatory telescopes. But it has a 100 times better angular resolution!
Skywatchers can readily view planets with just a modest or medium-sized telescope. How much of our solar system is visible will wow you! Additionally, you don't need a completely dark sky to see all of the planets in our solar system; a telescope can still make Venus, Mars, Jupiter, and Saturn easily visible even when viewed in a city. From $100 to well over $10,000, a telescope can be purchased. In 2022, you can anticipate that a good telescope for visual observing will start around $300 and a telescope capable of deep-sky astrophotography would start around $800. With a 25x telescope, even the tiniest telescope should be able to see Saturn's rings.

What is the Pythagorean theorem?Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We can apply this theorem only in a right triangle.
Example:
The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.
Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm
We have,
Quadrilateral ABCD.
The longer diagonal connects vertices A and C, and let E and F be the feet of the perpendiculars from vertices B and D to the longer diagonal AC.
From the figure,
BE = 20 m
DF = 30 m
AE = EC = 120/2 = 60 m
Now,
The area of the quadrilateral.
The area of a trapezoid.
= (sum of parallel sides) x (height) / 2
Using the Pythagorean theorem,
AB² = AE² + BE²
60² + 20² = 4000
AB = √(4000)
AB = 20 √10
And,
CD² = CE² + DF²
CD² = 60² + 30²
CD² = 4500
CD = √(4500)
CD = 15 √20
Now,
Area = AB + CD x 1/2 x AC
= 20√10 + 15√20 x 1/2 x 120
= 900√10
Therefore,
The area of the field is 900√10 m².

What does alpha 0.05 mean in stats?
An alpha value of 0.05 means that there is a 5% chance of incorrectly rejecting the null hypothesis.
In statistics, "alpha" is used to represent the significance level in a hypothesis test. The significance level, denoted by α, is the probability of rejecting the null hypothesis when it is actually true.
In other words, if the p-value in a hypothesis test is less than or equal to 0.05, we can reject the null hypothesis and conclude that there is a statistically significant difference between the groups or variables being tested.
An alpha value of 0.05 is commonly used in research studies, but other values such as 0.01 or 0.10 may also be used depending on the desired level of significance.

The cost of putting on a play is $500 for the theater rental, $500 for the actors, and $750 for set decorations and costumes. If tickets are sold for $25 each, how many tickets need to be sold to reach the break-even point?
Answer:
The total cost of putting on the play is $500 for theater rental + $500 for actors + $750 for set decorations and costumes = $1750.
To reach the break-even point, the revenue from ticket sales needs to equal the total cost, so $1750 = $25 x (number of tickets sold).
Solving for the number of tickets sold, we can divide both sides by $25: $1750 / $25 = (number of tickets sold).
This gives us: 70 = number of tickets sold.
Therefore, Mr. Curry needs to sell 70 tickets to reach the break-even point.

Answer:
B
Step-by-step explanation:
Using the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = final amount
P = principal (starting amount)
r = annual interest rate (as a decimal)
n = number of times interest is compounded per year
t = time (in years)
We can plug in the given values:
P = $1,500
r = 0.0825 (8.25% expressed as a decimal)
n = 1 (compounded annually)
t = 2
A = $1,500(1 + 0.0825/1)^(1*2)
A = $1,500(1.0825)^2
A = $1,757.71
Therefore, the total balance after 2 years will be $1,757.71. Answer choice B is correct.
