X/3+6-2x=-6 Please Help me I am stuck
Answers
Answer:
x = 36/5
Step-by-step explanation:
Subtract 6 from both sides
x/3+6-2x-6 = -6-6
Simplify
x/3 - 2x = -12
Multiply both sides by 3
x/3 * 3 - 2x * 3 = -12 * 3
Simplify
-5x = -36
Divide both sides by -5
-5x/-5 = -36/-5
Simplify
x = 36/5
The ladder of a fire truck extends 41 ft. to the top of the

Answer:
Step-by-step explanation:
By the Pythagorean Theorem a^2+b^2=c^2 or the sum of the squared sides is equal to the hypotenuse squared.
41^2=9^2+h^2

Answer:
8
Step-by-step explanation:
If the integer is n, half of it is n/2. The next integer is (n+1) and 1/3 of it is (n+1)/3. You want ...
n/2 - (n+1)/3 = 1
n(1/2 -1/3) -1/3 = 1
n/6 = 4/3 . . . . . . . . add 1/3, simplify
n = 6(4/3) = 8
The integer is 8.

Hello, happy Friday, I am just here with some geometry questions.
Please only answer this if you know the answer. If you have a comment, please add it to the comment box. Only answer the question if you can explain your answer and why you think it is accurate. Thanks, good luck!
Please determine if it is true or false and than explain why it is true or false.
Answers
a) False. This can be proven by the fact that a rotation around a point (not necessarily on the circles) can map 2 circles onto each other.
b) False. Rotations, reflections, and dilations (the last one applies if the circles have different radii) can map one circle onto another.
c) True. All circles are a uniform distance (the radius) from a point (the center), so there is only one length that defines a circle, the radius. Since a:b = a:b, where a = the radius of one circle while b = radius of another circle, that means that 2 circles will always be similar (because all corresponding lengths are in the same ratio)
Hope that helped!

Liquid A and liquid B are mixed to make liquid C.
Liquid A has a density of 70 kg/m Liquid A has a mass of 1400 kg
Liquid B has a density of 280 kg/m Liquid B has a volume of 30 m
Work out the density of liquid C.
Answers
Answer:
Density is defined as:
Density = mass/volume.
We know that:
For liquid A:
Density = 70kg/m^3
Mass = 1400kg
Then the volume is:
Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3
For liquid B:
Density = 280 kg/m^3
Volume = 30m^3
We can find the mass of liquid B as:
mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg
We know that liquid C is a mixture of liquid A and B.
Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:
Mass of liquid C = 1400kg + 8400kg = 9800kg
The same happens for the volume, then:
Volume of liquid C = 30m^3 + 20m^3 = 50m^3
Then the density of liquid C is:
Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3

Linda goes water-skiing one sunny afternoon. After skiing for 15 min, she signals to the driver of the boat to take her back to the dock. The driver steers the boat toward the dock, turning in a parabolic path as it nears. If Linda lets go of the towrope at the right moment, she will glide to a stop near the dock. Let the vertex of the parabola travelled by the boat be the origin. The dock is located 30 m east and 30 m north of the origin. The boat begins its approach to the dock 30 m west and 60 m north of the origin.a) If Linda lets go of the towrope when she reaches point A, where is she headed relative to the dock? Use an equation to describe the path. (Hint: She will travel in a straight line.) b) If Linda lets go of the towrope when she reaches point B, where is Linda headed relative to the dock?c) If Linda waits until point C, how close will her trajectory be to the dock?d) At what point should Linda release the towrope to head straight for the dock?e) What assumptions have you made?f) To make this situation more realistic, what additional information would you need? Create this information, and solve part d) using what you have created. As you work through the task, be sure to explain your reasoning and use diagrams to support your answers.A
Answers
a = 1/15
So y = (1/15)x^2
abc)
The derivative of this function is 2x/15. This is the slope of a tangent at that point.
If Linda lets go at some point along the parabola with coordinates (t, t^2 / 15), then she will travel along a line that was TANGENT to the parabola at that point.
Since that line has slope 2t/15, we can determine equation of line using point-slope formula:
y = m(x-x0) + y0
y = 2t/15 * (x - t) + (1/15)t^2
Plug in the x-coordinate "t" that was given for any point.
d)
We are looking for some x-coordinate "t" of a point on the parabola that holds the tangent line that passes through the dock at point (30, 30).
So, use our equation for a general tangent picked at point (t, t^2 / 15):
y = 2t/15 * (x - t) + (1/15)t^2
And plug in the condition that it must satisfy x=30, y=30.
30 = 2t/15 * (30 - t) + (1/15)t^2
t = 30 ± 2√15 = 8.79 or 51.21
The larger solution does in fact work for a tangent that passes through the dock, but it's not important for us because she would have to travel in reverse to get to the dock from that point.
So the only solution is she needs to let go x = 8.79 m east and y = 5.15 m north of the vertex.
What is 180/80=80/80*a^6

Step-by-step explanation:

[tex]\frac{180}{80}=\frac{80}{80}*a^6[/tex]
Required
Solve for a
[tex]\frac{180}{80}=\frac{80}{80}*a^6[/tex]
[tex]\frac{180}{80}=1*a^6[/tex]
[tex]\frac{180}{80}=a^6[/tex]
[tex]a^6 = \frac{180}{80}[/tex]
[tex]a^6 = \frac{18}{8}[/tex]
[tex]a^6 = \frac{9}{4}[/tex]
Take the square root of both sides
[tex]\sqrt{a^6} = \sqrt{\frac{9}{4}[/tex]
[tex]a^3 = \frac{3}{2}[/tex]
Take cube rooth of both sides

Lucy is out shopping and finds a $117.00 television that
was marked down by 10%.
How much was the item originally?
Answers
Answer:
$128.70
Step-by-step explanation:
To find the original answer, we must find what is 10% of $117.00. Move the decimal one place to the right and 10% is $11.70. Then add both $117.00 and $11.70, which equals $128.70 which was the original price.

Dan paid $11.98 for a 2.38-pound bag of shrimp at one store. The following week, he paid $19.49 for a 4.01-pound bag at another store.

Unit price for the 4.01-pound bag:
The better buy:
The 2.38-pound bag
The 4.01-pound bag
Neither (They have the same unit price)
Answers
Answer:
the unit price for the 2.38 pound bag $5.03 lb.
the unit price for the 4.01 pound bag $4.86 lb
The better buy: $4.86
The unit prices are $5.033 per pound and $4.85 per pound, and 4.01-pound bag is better buy choice.
What is unit price?The unit price refers to the price per unit of measures, such as price per pound, quart, ounce, or other units of weight or volume of the food package.
Given that, Dan paid $11.98 for a 2.38-pound bag of shrimp at one store, on other shop he spend $19.49 for a 4.01-pound bag,
We need to find the unit price of each and which one is the better buy,
The better buy will be the one having less unit rate,
Unit price for the 2.38-pound bag = 11.98 / 2.38 = $5.033 per pound
Unit price for the 4.01-pound bag = 19.48 / 4.01 = $4.85 per pound
Since, the unit price of the 4.01-pound bag is less therefore, this is the better buy choice.
Hence, the unit prices are $5.033 per pound and $4.85 per pound, and 4.01-pound bag is better buy choice.

The minute hand moves 60s per minute and a full rotation is 360° so: 360/60 = 6° per minute.
So in 20 minutes the minute hand will be 6 * 20 = 120° and the hour hand will be 120/12 = 10°.
so it would be 10°
