find the average of 2m,20cm and 95cm give your answer in cm
Answer:
The average is:
105 cm
Step-by-step explanation:
1 m = 100cm
2m = 2*100 = 200cm
then:
(200 + 20 + 95)/3 = 315/3 = 105cm
is n/2 a rational or irrational number
Answer:
it a rational number
Step-by-step explanation:
there is always an odd exponent. So it could not have been made by squaring a rational number! This means that the value that was squared to make 2 (ie the square root of 2) cannot be a rational number. In other words, the square root of 2 is irrational.

If two lines have slopes of -2/9 and 9/2 are they perpendicular?
Answer:
[tex]\huge\boxed{\mathrm{Yes.}}[/tex]
Step-by-step explanation:
If the two lines are perpendicular, Multiplying their slopes must give the result of -1.
So, Let's Multiply these slopes.=> [tex]\sf -\frac{2}{9} * \frac{9}{2}[/tex]
=> -1
Since, the result of multiplying these slopes give -1, So, the two lines are perpendicular.

The following equation involves a trigonometric equation in quadratic form. Solve the equation on the interval [0,2π).
2sin2x+sinx=1
Answer:
[tex]\dfrac{\pi}{6}, \dfrac{5\pi}{6}, \dfrac{3\pi}{2}[/tex]
Step-by-step explanation:
Given the quadratic equation as:
[tex]2sin^2x+sinx=1\\OR\\2sin^2x+sinx-1=0[/tex]
Let us put [tex]sinx=y[/tex] for simplicity of the equation:
Now, the equation becomes:
[tex]2y^2+y-1=0[/tex]
Now, let us try to solve the quadratic equation:
[tex]\Rightarrow 2y^2+2y-y-1=0\\\Rightarrow 2y(y+1)-1(y+1)=0\\\Rightarrow (2y-1)(y+1)=0\\\Rightarrow 2y-1 = 0, y+1 = 0\\\Rightarrow y = \dfrac{1}{2}, y = -1[/tex]
So, the solution to the given trigonometric quadratic equation is:
[tex]sinx = \dfrac{1}{2}[/tex]
and
[tex]sinx=-1[/tex]
Let us try to find the values of [tex]x[/tex] in the interval [tex][0, 2\pi)[/tex].
[tex]sin\theta[/tex] can have a value equal to [tex]\frac{1}{2}[/tex] in 1st and 2nd quadrant.
So, [tex]x[/tex] can be
[tex]30^\circ, 150^\circ\\OR\\\dfrac{\pi}{6}, \dfrac{5\pi}{6}[/tex]
For [tex]sinx=-1[/tex],
[tex]x = 270^\circ\ or\ \dfrac{3 \pi}{2}[/tex]
So, the answer is:
[tex]\dfrac{\pi}{6}, \dfrac{5\pi}{6}, \dfrac{3\pi}{2}[/tex]

Many farmers use the height of their corn on July 4th as an indication of the entire crop. In a random sample of corn-stalk heights on July 4th in Columbia County, x⎯⎯⎯x = 25.6, s = 0.9 inch, and a histogram of the observations was bell-shaped.
Fill in the blank. (Give your answer to two decimal places.)
The approximate proportion of observations that lies between 23.8 and 27.4 is __
Answer:
0.9544
Step-by-step explanation:
Given that, his bell shapes and hence follows a normal distribution.
Mean (x) = 25.6 ; standard deviation (s) = 0.9
Approximate proportion of observation that lies between 23.8 and 27.4
Taking the Zscores of both values :
X - mean / standard deviation
(23.8 - 25. 6) / 0.9 = - 1.8/0.9 = - 2
P(Z < - 2) = 0.0228
Also;
(27.4 - 25.6) / 0.9 = 1.8 / 0.9 = 2
P(Z> 2) = 0.9772
0.9772 - 0.0228 = 0.9544
5y + 2 + 6 + 2y 5y + 2(y + 3) + 2 combining like terms 6y − y + 2y + 10 − 4 + 2 Commutative Property Distributive Property arrowBoth arrowBoth arrowBoth
Answer:
Distributive Property
Step-by-step explanation:
5y + 2 + 6 + 2y
= 5y + 2(y + 3) + 2 This is the distributive property of multiplication w.r.t. addition
= 6y − y + 2y + 10 − 4 + 2
The distributive property of multiplication with respect to addition is the one which separates each term by using multiplication and then addition.
So we see that 2 is multiplied with y and 3 and then added with the like terms. If there was a minus sign the property would be distributive over subtraction.

Find an equation for a tangent plane z=e-x2-y2 at the point (0,0,1).
Answer: equation of the tangent plane is z = 1
Step-by-step explanation:
Given equation
z = e^(-x²-y²) at point (0,0,1)
now let z = f(x,y)
Δf(x,y) = [ fx, fy ]
= (-2xe^(-x²-y²)), (-2ye^(-x²-y²))
now
Δf (0,0) = [ 0, 0 ] = [ a, b ]
equation of the tangent plane therefore will be
z - z₀ = a(x-x₀) + b(y-y₀)
z - 1 = 0(x-0) + 0(y-0)
z - 1 = 0 + 0
z = 1
Therefore equation of the tangent plane is z = 1
Briyana has $150, and she needs to save at least $560 for a spring break trip. If she can save $45 per week, how long will it take her to save enough money? Let w= weeks saving money. Wrote an inequality to describe the situation.
Answer:
9.1 or 10 weeks
Step-by-step explanation:
First you need to create an equation: 150 + 45w = 560
You need to get the w by itself. To do this we need to take 150 from both sides: 150 (-150) + 45w = 560 (-150)
45w = 410
Now we have to divide both sides by 45:
w = 9.1
So it took Briyana just over 9 weeks to save $560 for spring break
I hope this helps
Let's work this out using the inequality it suggests.
We can use the form [tex]y=mx+b[/tex], but have the equals sign substitute out for whatever sign we need.
When you need to buy something, do you need to have more, less, or the same amount of money to buy something?
You need to have at least the same amount of money.
Which means that we'll be using the ≥ sign.
[tex]y\geq mw+b[/tex]
Now let's substitute in some values we know.
She has 150 to start off with, think of this as the y-intercept of the graph.
What variable represents the y-intercept?
You should've said b.
[tex]y\geq mw+150[/tex]
Now how much is she saving her week? $45.
Since this is how much she's saving every week, this represents the slope.
[tex]y\geq 45w+150[/tex]
Now, we can solve this plugging in 560 for [tex]y[/tex], which is how much money she needs.
[tex]560\geq 45x+150[/tex]
[tex]410\geq 45w[/tex]
[tex]\frac{82}{9}\geq w[/tex]
[tex]\frac{82}{9}[/tex] is 9.111 (repeating), but we need to round up to the nearest whole number because she probably doesn't deposit money constantly during the week, and rather all at once.
Which means that she needs to save money for 10 weeks to have enough money for the spring break trip.
Hope this helps.

if an area can be washed at a rate of 4,900 cm2/ minute, how many square inches can be washed per hour?
Answer : 4.5 × 10⁴ square inches can be washed per hour.
Step-by-step explanation :
As we are given that an area can be washed at a rate of 4,900 cm²/min. Now we have to determine the square inches can be washed per hour.
Given conversions are:
1 cm = 0.39 in and 1 hr = 60 min
As, 1 cm² = (0.39)² in² and 1 min = 1/60 hr
So, [tex]1cm^2/min=(0.39)^2\times 60in^2/hr[/tex]
[tex]1cm^2/min=9.126in^2/hr[/tex]
Now we have to determine the square inches can be washed per hour.
As, [tex]1cm^2/min=9.126in^2/hr[/tex]
So, [tex]4900cm^2/min=\frac{4900cm^2/min}{1cm^2/min}\times 9.126in^2/hr=44717.4in^2/hr=4.5\times 10^4in^2/hr[/tex]
Therefore, 4.5 × 10⁴ square inches can be washed per hour.

1 liter is equivalent to a volume of 1000 cm3 (the same as 10 cm x 10 cm x 10 cm). If a beaker has a cross-section the size of the circle below, and a height of 10 cm, what is its volume
Answer:
[tex]Volume = \frac{220}{7}r^2[/tex]
Step-by-step explanation:
Given
Height = 10cm
See Attachment for complete question
Required
Determine the volume of the circle
The volume is calculated as thus;
[tex]Volume = \pi r^2h[/tex]
Take [tex]\pi[/tex] as [tex]\frac{22}{7}[/tex]
So; Volume becomes
[tex]Volume = \frac{22}{7} * r^2 * h[/tex]
Substitute 10 for h
[tex]Volume = \frac{22}{7} * r^2 * 10[/tex]
[tex]Volume = \frac{220}{7} * r^2[/tex]
Since, the value of the radius is not given;
The volume of the circle is:
[tex]Volume = \frac{220}{7}r^2[/tex]

The angle above the y is 90 degrees ( shown by the little square)
The 3 inside angles of a triangle need to equal 180.
Y = 180 - 90 - 48
Y = 42
Answer: y = 42°
Step-by-step explanation:
Triangle Sum Theorem states the sum of the angles of a triangle is 180°
y + 48° + 90° = 180°
y + 138° = 180°
y = 42°

So overall Dominique gets $3 plus $1.25/mile and totals out $11.75
If we call the miles driven x, like they say, then the equation for earnings is:
1.25x+3=11.75
or some variation of that. We can see that as option 4, but a closer look at the other options shows us that options 2 and 3 are also true. These choices are simply the original equation correctly multiplied by a factor of 2 (the other options are incorrect multiplications).
So those are our answers.
