Given y varies inversely as x, and y = 5 when x = 9. *Write the inverse function
Answer:
y = k/x
k = 45
y = 45/x
Step-by-step explanation:
y varies inversely as x
y = k/x
y = 5 when x = 9
y = k/x
5 = k / 9
Cross product
5 * 9 = k
k = 45
Constant of proportionality, k = 45
y = 45/x
which of the following is the value of x?
9514 1404 393
Answer:
x = 20°
Step-by-step explanation:
Assuming parallel lines, the two angles marked with measures are complementary to each other.
45° +(5x +35°) = 180°
5x = 100° . . . . . . . . . . . . subtract 80° from both sides
x = 20° . . . . . . . . divide by 5

Comment on the geometry
Where a transversal crosses parallel lines, all of the obtuse angles are congruent, and all of the acute angles are congruent. Of course, the acute angles and obtuse angles are linear pairs, hence supplementary. (The only time this won't apply is when all angles are right angles.)
No lines are marked as parallel here, nor does any part of this problem statement say there are parallel lines. So, we cannot find the value of x if we're going strictly by what is shown in the diagram. In the absence of any information, we can only say that the angle marked with an x-expression must be between 0° and 180°.
0 ≤ 5x +35 ≤ 180 ... -35 ≤ 5x ≤ 145 ... -7 ≤ x ≤ 29.

Step-by-step explanation:
So there are ways to find a missing side of a triangle.
Pythagorean TheoremLaw of SinesLaw of CosinesSine,Tangent, or Cosine Function.I'll explain when we use them,
We use pythagorean theorem if we have a right angle and know at least two sides of a triangle. Since we dont know two sides, we are not going to use that.We use law of sines if we know a given angle and a side opposite of that angle and a side or angle opposite of the angle or side we are trying to findIf we apply the triangle interior theorem, we can use law of sines. Since 11 and 44 degrees are opposite sides, and x and the missing angle which is 46 is opposite side and angle as well.We use law of Cosines if we know two sides and a angle between them. We have a missing side so we cant use law of Cosines.Since we are trying to find side measures, sometimes it isn't advised to use SOHCAHTOA.So let use law of sines.[tex] \frac{11}{ \sin(44) } = \frac{x}{ \sin(46) } [/tex]
[tex] \frac{11}{ \sin(44) } \times \sin(46) = x [/tex]

Two trains started from the same station at the same time and traveled in opposite
directions. After traveling 4 hours, they were 480 miles apart. The rate of the fastest
train exceeded the rate of the slow train by 10 mph. Find the rate of each train.
Please help!!
Answer:
Fastest train: 65 mph
slowest: 55 mph
Step-by-step explanation:
Divide 480 by 4
=120
To find average speed divide 120 by 2
=60
call the speed of the slowest train y.
y+(y+10)=120
2y=110
y=110/2=55
y+10=65
Hope this helps!! :)
Please help on this!!! Thanks!!

Answer:
[tex]\sqrt{32}[/tex]
Step-by-step explanation:
Pythagorean - [tex]a^2+b^2=c^2[/tex]
where a and b = legs and c = hypotenuse
For the following problem we are given the hypotenuse ( [tex]\sqrt{84}[/tex] ) and a leg ( [tex]\sqrt{52}[/tex] ) and we need to find the missing side length ( which also happens to be a leg.)
That being said we can find the missing leg by plugging in what we are given into [tex]a^2+b^2=c^2[/tex] ( let a = missing side length )
[tex]a^2+\sqrt{52}^2=\sqrt{84} ^2\\\sqrt{52} ^2=52\\\sqrt{84}^2 =84\\a^2+52=84[/tex]
* subtract 52 from each side
84 - 52 = 32
52 - 52 cancels out
we now have a² = 32
step 2 take the square root of each side
[tex]\sqrt{a^2} =a\\\sqrt{32} =\sqrt{32}[/tex]
Assuming that we are supposed to leave the answer in radical form the answer would be sqrt 32
Answer:
7 in.
Step-by-step explanation:
Let x = the length of the missing side
[tex]x^{2} + \sqrt{32} ^{2} = \sqrt{81} ^{2}[/tex]
[tex]x^{2} +32 = 81[/tex]
[tex]x^{2} = 49\\[/tex]

Amy has a piece of wood that measures 42 inches. The model shows the length remaining after she cut a piece from the 42-inch piece of wood. About how many inches did Amy cut from the 42-inch piece of wood?
Answer:
She has 42 pieces of wood each of 1 inch of length.
Step-by-step explanation:
Amy has 42 inches piece of wood.
She has to cut an inch.
After cutting pieces of inch each she counts the pieces to be 42.
Mathematically
Total length / unit lenght = Number of pieces
42 inches/ 1 inch= 42 pieces.
She has 42 pieces of wood each of 1 inch of length.

Find the lateral surface area of the can of mandarin oranges. Round your answer to the nearest tenth. Radius: 4cm, Height: 11cm
Answer:
276.3cm²
Step-by-step explanation:
The lateral surface area is the area of all the sides of a 3-dimensional object excluding its base and top.
A can is in the shape of a cylinder
Lateral surface area of a cylinder = 2πrh
π = pi = 3.14
h = height = 11
r = radius = 4
2 x 3.14 x 4 x 11 = 276.32 cm²
to the nearest tenth = 276.3 cm²
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Which correctly describes a cross section of the square pyramid? Select three options. A square pyramid with 2 foot sides. A cross section parallel to the base is a square with side lengths of 2 ft. A cross section parallel to the base is a square with side lengths of less than 2 ft. A cross section perpendicular to the base through the top vertex is a triangle with the same dimensions as the triangular sides of the pyramid. A cross section perpendicular to the base through the top vertex is a triangle with different dimensions than the triangular sides of the pyramid. A cross section that is perpendicular to the base that does not pass through the top vertex of the pyramid is a trapezoid.

Find the missing term: (x+3)² = x² + 6x + _____
Answer:
9
Step-by-step explanation:
The formula for (a + b)^2 expands out to: a^2 + 2ab + b^2. In the case of this problem, a equals x and b equals 3. We can substitute to get:
(a + b)^2 = a^2 + 2ab + b^2
(x + 3)^2 = x^2 + 2(x)(3) + (3)^2
(x + 3)^2 = x^2 + 6x + 9
So, the missing term is 9.
Another way to do this is to multiply (x + 3)(x + 3) since it's the same thing:
(x + 3)(x + 3)
x^2 + 3x + 3x +9
x^2 + 6x + 9
By solving this way, you get the same answer.
Answer:
It would be 9.
Step-by-step explanation:
To do this, lets expand the equation (x+3)^2 by turning it into:
(x+3)(x+3)
Now, lets try something called the FOIL method. This is where all of the terms of the equation are multiplied in the order:
1) First
2) Outer
3) Inner
4) Last
So in (x+3)(x+3), each of the first parts of each parentheses box are x's, and x times itself equals x^2 so:
x^2 + ? + ? so far.
Next, with the Outer & Inner parts, they would be x * 3 and 3 * x. With this, you would get 3x and 3x. These can be added to get 6x, the middle part of the equation.
x^2 + 6x + ? so far.
Lastly, for the answer. Time to do the last part of each parentheses box, you would get 3 * 3, which gives you 9.
x^2 + 6x + 9.

What is the area in square feet of the shaded part of the rectangle below
7. Solve for x:
8. Find m
Answer:
From Triangles...
The sum of two opposite interior angles = the exterior
so
3x-2 + 9x + 7 = 14x - 19
12x +5=14x -19
Collecting Like terms
2x= 24
x= 12°.
For "m"
Sum of angles in a triangle=180°
So
180 - (19x-3+9x-2) = m
180 -(28x -5) =m
m= 180 - 28x + 5
m=185 - 28x.
Now
Since sum of everything in a triangle = 180
185 - 28x + 9x -2 + 19x - 3 = 180
185 -28x + 28x -5= 180
185-5=180
180=180

Answer:
Slope: 5, Y-intercept: 150
Step-by-step explanation:
=> Slope = Change in y / Change in x
Change in y = +35
Change in x = +7, therefore;
Slope = 35 / 7
Slope = 5
=> Y-intercept is the y-value where x = 0, therefore;
Y-intercept = 150

18 is 4.5 times a number.
The value of x is equal to 4, that is 4.5 times 18 is 4
Given that the expression:
18 is equal to 4.5 times a number.
Assume that the number be x.
To find the number that is 4.5 times 18, we can set up the following equation:
4.5 × x = 18
Now, to find the value of x, divide both sides of the equation by 4.5:
4.5 × x / 4.5 = 18 / 4.5
x = 18 / 4.5
x = 4
So, the number that is 4.5 times 18 is 4.
