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.
Ronald's home is located 33 miles west and 56 miles north from his hotel. Find the distance from his hotel to his home.
The distance from his hotel to his home is 89 miles.
What is the distance?Distance is defined as an object's entire movement without regard for direction. The distance can be defined as how much ground an object has covered regardless of its starting or ending place.The quantity of space between two things, or the state of being far apart, is defined as distance. A five-foot gap between two tables is an example of distance. The disparity between two sides of an issue is an example of distance.Solution -Given - Ronald's home is located 33 miles west and 56 miles north of his hotel.
To find the distance between Ronald's hotel to his home, add the distance.
∴ [tex]33 + 56 = 89[/tex]
Therefore, the distance from his hotel to his home is 89 miles.

Part A: The sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 1.55 ⋅ 107 seconds? (5 points)
Part B: Which is the more reasonable measurement of the diameter of a human hair:
1.8 ⋅ 10−2 mm or 1.8 ⋅ 102 mm? Justify your answer. (5 points)
Please Explain.
Part A: The amount of ergs of radiant energy, Q produced in time t = 1.55 × 10⁷ s is 6.045 × 10⁴⁰ ergs.
Since the sun produces 3.9 × 10³³ ergs of radiant energy per second, which is a rate, r = 3.9 × 10³³ ergs/s.
We require the amount of ergs of radiant energy, Q produced in time t = 1.55 × 10⁷ s.
So, this heat Q = rate × time
Q = rt
Substituting the values of r and t into the equation, we have
Q = 3.9 × 10³³ ergs/s × 1.55 × 10⁷ s
Q = 6.045 × 10³³ × 10⁷ ergs
Q = 6.045 × 10⁴⁰ ergs
So, the amount of ergs of radiant energy, Q produced in time t = 1.55 × 10⁷ s is 6.045 × 10⁴⁰ ergs.
Part B: The measurement of the diameter of human hair 1.8 × 10⁻² mm is more reasonable.
Since 1.8 × 10⁻² mm = 1.8 × 10⁻² mm × 1cm/10 mm = 1.8 × 10⁻³ cm (since 10 mm = 1 cm) and
1.8 × 10² mm = 1.8 × 10² mm × 1 cm/10 mm = 1.8 × 10 cm = 18 cm (since 10 mm = 1 cm)
Since the human hair is small and its diameter of human hair cannot be 18 cm since 18 cm is a large diameter, then the diameter of the human hair has to be 1.8 × 10⁻³ cm = 1.8 × 10⁻² mm which is a small value.
So, measurement of the diameter of human hair 1.8 × 10⁻² mm is more reasonable.

can i get some help. did it 3 times and still not sure.
Answer:
18
Step-by-step explanation:
The height of the cone is 8, and the diameter is 3. This means that the radius is 3/2, or 1.5. We can plug everything into the formula (using 3 for pi):
[tex]\frac{3(1.5)^2(8)}{3}[/tex]
We can cancel out the 3 from the numerator and the denominator, so we are left with 1.5^2 times 8. 1.5 squared is equal to 2.25, and 2.25 times 8 is equal to 18.
Since a sample data shows that a linear correlation coefficient between two variables is about 0.08, then it rules out a possible causal relationship between the two variables.
Answer:
False
Explanation:
A linear correlation coefficient is used to measure the the level of relationship between two seemingly dependent and independent variables. A relationship exists between two variables in linear correlation if one affects the other, either negatively or positively never zero. If linear correlation has a negative value then one variable increases while the other decreases. If linear correlation coefficient is positive then both variables increase together. If zero then there is no relationship as one variable's increase or decrease has nothing to do with the other. In the case above, correlation is positive at 0.08 hence we can say that there is a relationship between the two variables.

B. 784pi units3
C. 98pi units 3
D. 112pi units 3
Answer:
196π units^3
Step-by-step explanation:
The volume of a cylinder is:
πr^2h
SINCE, there is no given pi, the formula will be:
r^2h
Use the formula on the given dimensions:
r^2h
= (7^2) 4
= (49) 4
= 196
So we could just leave the final answer as:
196π
The real volume will be solved once π is given.
I hope I helped!
The volume of the cylinder given is 196 π, Option A is correct.
The volume of the cylinder is given by V=πr²h
Where r is radius of cylinder and h is the height of the cylinder.
V is the volume
r=7
h=4
Now plug in these values in volume formula.
V=π(7)².4

Find the value of x^3 + y^3 + z^3 – 3xyz if x^2 + y^2 + z^2 = 83 and x + y + z = 15
Answer:
180
Step-by-step explanation:
Consider the equation x + y + z = 15
From algebraic identities, we know that (a + b + c)^2 = a^2 + b^2 + c^2 + 2(ab + bc + ca)
So,
(x + y + z)^2 = x^2 + y^2 + z^2 + 2(xy + yz + xz)
From the question, x^2 + y^2 + z^2 = 83 and x + y + z = 15
So,
152 = 83 + 2(xy + yz + xz)
=> 225 – 83 = 2(xy + yz + xz)
Or, xy + yz + xz = 142/2 = 71
Using algebraic identity a³ + b³ + c³ – 3abc = (a + b + c)(a² + b² + c² – ab – bc – ca),
x3 + y3 + z3 – 3xyz = (x + y + z)(x² + y² + z² – (xy + yz + xz))
Now,
x + y + z = 15, x² + y² + z² = 83 and xy + yz + xz = 71
So, x^3 + y^3 + z^3 – 3xyz = 15(83 – 71)
=> x^3 + y^3 + z^3 – 3xyz = 15 × 12
Or, x^3 + y^3 + z^3 – 3xyz = 180

Josie parents opened a college
savings account that pays yearly
simple interest of 5.5%. They opened
the account with $500 and adds $50
each month to her account. How
much money is in her account at the
end of 4 years?
Record your answer and fill in the
bubbles on your answer document.
Be sure to use the correct place
value.
Answer:
$4,208.5
Step-by-step explanation:
The simple interest rate of the college savings account, R = 5.5%
The amount with which the account was opened, P = $500
The amount added each month to her account = $50
The amount in her account after 4 years = Required
The interest on each added $50 is given as follows;
50 × 0.055/12 × (1 + 2 + 3 + ... + 47) = 50 × 0.055/12 × (47/2)(1 + 47) = 258.5
The total amount deposited = 500 + 50 × 47 = $2,850
The total interest = 500×0.55×4 + 50 × 0.055/12 × (47/2)(1 + 47) = 1,358.5
The amount in her account at the end of 4 years, A, is given as follows
A = $2,850 + $1,358.5 = $4,208.5

To evaluate the function, I plug in 3 for "x" :

[tex]\rm{f(3)=2(3)^2+1}[/tex]
Then, I square 3:
[tex]\rm{f(3)=2\times9+1}[/tex]
Take caution here; we do not add 9 + 1, we multiply 2 times 9 first, and only then, we add 1.

Use a double-angle or half-angle identity to find the exact value of each expression?
If 0 < θ < π/2, then 0 < θ/2 < π/4, and for such angles we expect sin(θ/2) to be positive. Also, we know both sin(θ) and cos(θ) will be positive.
Given that tan(θ) = 2, we can find sec(θ) from the Pythagorean identity:
tan²(θ) + 1 = sec²(θ) ==> sec(θ) = √(tan²(θ) + 1)
… ==> cos(θ) = 1/√(tan²(θ) + 1)
… ==> cos(θ) = 1/√5
Now, recall the half-angle identity for sine:
sin²(θ/2) = (1 - cos(θ))/2
==> sin(θ/2) = √[(1 - cos(θ))/2]
==> sin(θ/2) = √[(1 - 1/√5)/2]
==> sin(θ/2) = √[(√5 - 1)/(2√5)]
==> sin(θ/2) = √[(5 - √5)/10]
