Mr. White and Co. has total profit of 6/7 million dollars. The spinning department gave a profit 1/4 of million dollars. Find the fraction of profit from other departments.
Answer: 17/28
Step-by-step explanation:
Since there is a total profit of 6/7 million dollars and the spinning department gave a profit of 1/4 million, then the profit gotten from other departments will be the fraction of profit from the spinning department subtracted from the total profit. This will be:
= 6/7 - 1/4
= 24/28 - 7/28
= 17/28
The fraction of profit from other department is 17/28.
if the mean of x1,x2,x3 and x4 is 6 then find the mean of x1+10,x2+8,x3+16 and x4+2
Answer:
f the mean of this set is equal to 20, we can write down the below equation,
20 = (x1 + x2 +x3 + .... + x10)/10
x1 + x2 + x3 + ... x10 = 200
Then we can also write an equation for the mean of the given numbers as below,
Mean = [(x1+4) + (x2+8) + (x3+12) + .... + (x10+40)]/10
= (x1 + x2 + x3 + ... + x10 + 4 + 8 + 12 + ... + 40)/10
Then we can use above equation (1) to replace x1 + x2 + x3 + ... + x10 by 200
Mean = (200 + 4 + 8 +12 + 16 + 20 + 24 + 28 + 32 + 36 + 40)/10
= 420/10
= 42
If you remember Arithmetic Progressions you can simply add together the above number set.
If you closely look above, you can find that there is an Arithmetic Progression : 4, 8, 12, ... , 40
Here we want the addition of 10 terms. So we can use,
Sn = n/2(a+l)
S10 = 10/2(4+40)
= 220
Then you can easily get the answer,
Mean = (200 + 220)/10
= 42

8
Answer:
14
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side /adj side
tan theta = 8/33
taking the inverse tan of each side
tan^-1 (tan theta) =tan^-1 (8/33)
theta = tan ^-1 (8/33)
theta =13.62699486
To the nearest degree
theta = 14

First you find the area of the circle and then you subtract it from the area of the square to get your answer.
Hope it helps c:
Answer: Choice A) about 69.53 m^2
==========================================================
Work Shown:
A = area of the square
A = side*side
A = 18*18
A = 324 square meters
---------
B = area of the circle
B = pi*r^2
B = pi*9^2 ..... note that the radius is half the diameter
B = 81pi
B = 254.469004940773
B = 254.4690 square meters
I used the calculator's stored version of pi to compute that approximate value.
---------
C = area of shaded region
C = A - B
C = 324 - 254.4690
C = 69.531
C = 69.53 square meters
So that points us to choice A as the final answer.
---------
Side note: The shaded region is about C/A = (69.531)/(324) = 0.2146 = 21.46% of the square's area. So this is the approximate chances of landing in the shaded area if you randomly threw a dart.

8. Anneke is swimming the 500-meter freestyle, which consists of swimming the length of a pool 20 times. If Anneke averages 26.4 seconds per length of pool, write an equation that could be used to determine the number of meters (m) Anneke has left in the event after swimming for s seconds.
Answer:
Anneke will swim 20 lengths in the 500-meter event,
which means each length of the pool is = 500/20
= 25m
also since Anneke can swim one length in 26.4 seconds on average
hence her average speed is = 25/26.4 m/s
hence after a seconds,
the distance traveled = 25s/26.4 meter
thus, the remaining distance Anneke need to travel is:
m = 500 - (25s/26.4)
find the value of the unknown.
Answer:
86.5
[tex]14 + 8 + 12.5 = 34.5 \: \: 121 - 34.5 = 86.5[/tex]
Rohann recently finished some renovations to his house. 20 square meters of carpeting cost $875 while 17 square meters of hardwood flooring cost $750. Which flooring is more expensive per square meter?
Answer: Hardwood flooring
Step-by-step explanation:
Given
Rohann renovation of Carpentering cost $875 for [tex]20\ m^2[/tex]
For hardwood flooring [tex]17\ m^2[/tex] cost $750
So, cost per square meter for different floors are
[tex]\Rightarrow \text{Carpentering}=\dfrac{875}{20}\\\\\Rightarrow \text{Carpentering}=\$43.75/m^2[/tex]
[tex]\Rightarrow \text{Hardwood}=\dfrac{750}{17}\\\\\Rightarrow \text{Hardwood}=\$44.11/m^2[/tex]
Thus, the cost of the Hardwood flooring is more expensive.

Answer:
1458Step-by-step explanation:
As per the question we are looking for a number which is a multiple of the greatest possible exponent of 3.
Let's see the exponents of 3 within 1-2017 interval:
3¹ = 3, 3²= 9, 3³ = 27, 3⁴ = 81, 3⁵ = 243, 3⁶ = 729, 3⁷ = 2187 > 2017As we see the greatest exponent of 3 is 729.
There are two multiples of 729 in the given interval:
729*1 = 729 and 729*2 = 1458So the last number is 1458

Which of the following is a defined term?
Angle
Line
Point
Plane
Angle is a defined term.
What is defined term?
In geometry defined term, that have a formal definition and can be defined using other geometrical terms is called a defined term.
According to the given question
We have some terms
Angle, Line, Point and Plane
Now,
In geometry, we can define an angle using undefined term of a line. That is we define an angle as the corners that are created when two non-parallel lines intersect each other, so angle is a defined term.
In Geometry, we define a point as a location or size .
A line is defined as something that extends infinitely in either direction but has no width and is one dimensional.
While plane extends infinitely in two dimensions.
Hence, line, point and plane are undefined terms.

Step-by-step explanation:
A polynomial p has zeros when x = -2, x = 1/3, and x =3.
What could be the equation of p? Choose 1 answer:
a. p(x) = (x + 2)(x + 3)(3x + 1)
b. p(x) = (x + 2)(x + 3) (3x - 1)
C. p(x) = (x + 2)(x - 3)(3x - 1)
D. p(x) = (x - 2)(x + )(3x + 1)
Answer:
p(x) = ( x +2) (3x - 1) ( x-3)
Step-by-step explanation:
We know the equation for a polynomial with given zeros is
f(x) = a(x-b1) (x-b2)...... where b are the zeros and a is a constant
Since the zeros are x = -2, x = 1/3, and x =3.
p(x) = a( x - -2) (x - 1/3) ( x-3)
p(x) = a( x +2) (x - 1/3) ( x-3)
We can pick the value of a since we are not given a point on the function. Pick a=3
p(x) = 3( x +2) (x - 1/3) ( x-3)
Rewriting the second term
p(x) = ( x +2) (3x - 1) ( x-3)

Can someone help me with this math homework please!
===============================================================
Explanation:
Unfortunately your teacher is a bit vague here, but I'm assuming that the roots listed in the table are the only roots (and there aren't any other roots possible). If other roots were possible, then we'd have infinitely many possible answers and it would greatly muddy up the problem.
So we'll just stick to the basic assumption that the only roots are: -2, 0, and 2.
With that key assumption in mind, let's look at the answer choices to see which are true and which are false.
A) False. This is because we see that f(x) = -15 when x = -3. Note how x = -3 is in the interval [tex](-\infty, 3)[/tex]. In other words, this is a counter example showing that f(x) > 0 is not the case when x is between -infinity and 3.B) True. Over the interval [tex]0 \le x \le 2[/tex], we have f(x) either equal to 0 or a negative value. For the interval 0 < x < 2, we would have f(x) < 0.C) False. The table shows that f(0) = 0 which means we aren't making f(x) < 0 to be the case. D) True. The table shows that if -2 < x < 0, then f(x) is positive. An example of this is f(-1) = 3 which is positive. The f(x) values in this region are above the x axis. E) True. We have f(x) either equal to 0 or something larger when [tex]x \ge 2[/tex] which translates over to the interval notation [tex][2, \infty)[/tex]From that list above, we see that choices B, D and E are true.
