You buy butter for $3 a pound.
One portion of onion compote requires 1.7 oz of butter.
How much does the butter for one portion cost? Round to the nearest cent.
There are 16 ounces in one pound.
Set up a proportion and solve for x.
3/x = 16/1.7
16x = 3(1.7)
16x = 5.1
x = 5.1 ÷ 16
x = 0.31875
Rounding to the nearest cent, we get 30 cents.
What is the domain of the square root function graphed below?
Answer:
The domain of the graph must be [tex]x\ge \:-4[/tex].
Therefore,
[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
Hence, option a is true.
Step-by-step explanation:
From the graph, it is clear that the graph is heading towards positive infinity from x=-4.
The point x=-4 is included in the graph as the starting point of the graph i.e. x=4 is showing a closed circle on x=4, and heading towards positive infinity onward.
i.e. [-4, ∞)
Hence, the domain of the graph must be [tex]x\ge \:-4[/tex].
Therefore,
[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
Hence, option a is true.

Area of the triangle XYZ = [tex]\frac{1}{2}(\text{Height})(\text{Base})[/tex]
Height of the triangle = AY
Base of the triangle = XZ
To get the length of any segment we will use the formula,

First Degree Equations
A first-degree equation can have one, none, or infinitely many solutions.
An equation like
2x + 3 = -x + 6
Has one solution: x=1
An equation like:
4x + 2 = 4x + 1
Has no solutions because when trying to solve for x we get:
2 = 1
This equality is false and no value of x can make it true
Finally, the equation:
3x + 2 = x + 2x + 2
Has infiniteyl many solutions, because when trying to solve it, we get:
2 = 2
Which is true regardless of the value of x
The first given equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation not having solutions, we should have 8x plus any number but 9 on the right side of the equation:
8x + 9 = 8x -3, or
8x + 9 = 8x + 4
The second given equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
If the equation has one solution, the only condition is that we should not have 8x on the right side. Thus any of those will do:
8x + 9 = 3x + 9
8x + 9 = -x + 5
8x + 9 = 0
The third equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation to have infinitely many solutions, the right side must be exactly equal to the left side:
8x + 9 = 8x + 9

A box on an angle signifies a 90° angleAll angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation

Combine like terms: x + 120 = 180Subtract 120 on both sides: x = 60°A person 6ft tall stands 10ft from point P directly beneath a lantern hanging 30 ft above the ground. The lantern start to fall, thus causing the person shadow to lengthen(L). Given that the lantern falls 16t2 feet in t seconds, how fast will the shadow be lengthening when t=1
Answer:
[tex]\frac{dL}{dt}=30 \frac{ft}{s}[/tex]
Step-by-step explanation:
In order to solve this it is always a good idea to start by drawing a diagram of the situation (See attached picture).
From the diagram we can see that we are dealing with similar triangles. We can use similar triangles to build an equation that relates the length of the shadow with the height of the lamp, so we get:
[tex]\frac{L}{6}=\frac{10+L}{h}[/tex]
the height of the lamp can be found by subtracting the [tex]16t^{2}[/tex] distance the lamp falls in a given time t from the original 30ft the lamp was located at.
So the equation will now lok like this:
[tex]\frac{L}{6}=\frac{10+L}{30-16t^{2}}[/tex]
So now we can solve the equation for L, we can start by multiplying by the LCD SO WE GET:
[tex]L(30-16t^{2})=6(10+L)[/tex]
next, we can distribute the right side of the equation so we get:
[tex]L(30-16t^{2})=60+6L[/tex]
and subtract 6L from both sides so we get:
[tex]L(30-16t^{2})-6L=60[/tex]
and factor L, so we get:
[tex]L(30-16t^{2}-6)=60[/tex]
and solve for L:
[tex]L=\frac{60}{24-16t^{2}}[/tex]
now, we can differentiate this equation by using the chain rule, so we get:
[tex]dL=-\frac{60}{(24-16t^{2})^{2}}(-32t)dt[/tex]
which can be simplified to:
[tex]\frac{dL}{dt}=\frac{1920t}{(24-16t^{2})^{2}}[/tex]
and now we can substitute t for 1s so we get:
[tex]\frac{dL}{dt}=\frac{1920(1)}{(24-16(1)^{2})^{2}}[/tex]
[tex]\frac{dL}{dt}=30 \frac{ft}{s}[/tex]

PLEASE HELP!! solve |2x-2| ≥6.
x ≤ -2 OR x ≥ 4
__________________________________________________________
Step-by-step explanation:We are given the inequality:
|2x - 2| ≥ 6
Getting rid of the Modulus:
Since 2x-2 is in modulus:
|2x-2| = -(2x-2) OR 2x-2
(since the modulus of both these values is 2x-2)
Hence, our inequality can be written in 2 different ways:
2x-2 ≥ 6 (if 2x-2 ≥ 1)-(2x - 2) ≥ 6 (if 2x-2 < 0)__________________________________________________________
Solving these 2 inequalities:
Solving inequality 1:
2x - 2 ≥ 6
2x ≥ 8 [adding 2 on both sides]
x ≥ 4 [dividing both the sides by 2]
This is the solution of the inequality if: 2x-2 ≥ 0
Solving Inequality 2:
-(2x-2) ≥ 6
It can be rewritten as:
2 - 2x ≥ 6
2 ≥ 6 + 2x [adding 2x on both the sides]
-4 ≥ 2x [Subtracting 6 from both sides]
x ≤ -2 [Dividing both sides by 2]
This is the solution of the given inequality if: 2x-2 < 0
__________________________________________________________
Solution of the given Inequality:
Therefore, the solution of the given inequality |2x-2| ≥ 6 are:
x ≥ 4 (if 2x-2 ≥ 0)
x ≤ -2 (if 2x-2 < 0)
Hence, option C is correct!

a company makes two different-sized ice cream cones. The smaller cones are 3.5 inches tall and have a diameter of 3 inches. The larger cones are 5.1 inches tall and have a diameter of 4.5. inches. About how much greater, to the nearest tenth of a cubic inch, is the volume of the larger cone than the volume of the smaller cone?
9514 1404 393
Answer:
18.8 cubic inches
Step-by-step explanation:
The formula for the volume of a cone is useful:
V = 1/3πr²h
Where r is half the diameter, we can use r=d/2 to write this in terms of diameter:
V = 1/3π(d/2)²h = (π/12)d²h
For the given dimensions, the volumes are ...
large cone: v = (π/12)(4.5 in)²(5.1 in) ≈ 27.04 in³
small cone: v = (π/12)(3 in)²(3.5 in) ≈ 8.25 in³
Then the difference in volume is ...
(27.04 -8.25) in³ ≈ 18.8 in³
The larger cone has about 18.8 cubic inches more volume.

If the parallel lines m and n are 6 units apart, how many units of translation is equivalent to the composition of two reflections over lines m and n?
9514 1404 393
Answer:
12 units
Step-by-step explanation:
Reflection over two lines x units apart is equivalent to a translation of 2x units. Since the given lines are 6 units apart, ...
the equivalent translation is of 12 units.
___
Example:
Lines at x=0 and x=6. Point (x, 0). After reflection over x=0, the point is located at (2·0 -(x), 0) = (-x, 0). After reflection of that over x=6, the point is located at (2·6 -(-x), 0) = (12 +x, 0). That is, 12 has been added to the x-coordinate, meaning the point was translated 12 units. (The translation is in the direction the second line is from the first.)
