Using the MACRS rates from the following table,
what is the book value of a $3,500 computer after 2
years?
Year MACRS Rate
1
20.0 %
2 32.0 %
3 19.2 %
4 11.52 %
5 11.52 %
book value = [?]
The book value of a $3,500 computer after 2 years is $2380
How to calculate book value
The book value is gotten by subtracting the product of the initial value and MACRS rate from the initial value.
The book value after 2 years = 3500 - (32% of 3500)
The book value after 2 years = 3500 - (0.32 * 3500) = 2380
The book value of a $3,500 computer after 2 years is $2380

Cheryl wants to save at least $500 to buy a video game console. She already has $100 saved up and is going to babysit for $20 an hour until she can save up the rest. Write an inequality to represent this scenario, then solve the inequality to find out the minimum number of hours she must babysit to save a total of $500?
Answer:
x + 5 ≥ 25 [Inequality]
Minimum no. of hours = 15 hours
Step-by-step explanation:
Given :-
Price of video game console = $500
Money in hand = $100
Rate at which money is gained = $20/h
To Find :
Inequality to represent the situation
Variables :-
h = number of hours
Solving :-
20x + 100 ≥ 500
x + 5 ≥ 25 [Inequality]
x + 5 ≥ 20
x ≥ 15
Minimum no. of hours = 15 hours

A solid shape is made by joining two cones. Each cone has the same radius. One cone has The other cone has slant height = 2x radius The total surface area of the shape is slant height = 3x radius 57.8 pi cm^ 2 Curved surface area of acone = pi*r * l where r is the radius and I is the slant height Work out the radius. Each cone has the same radius.
The given area of the shape of 57.8·π cm², and length of the slant sides
being a factor of the radius, gives the length of the radius as 3.4 cm.
How can the length of the radius be calculated?Given;
Radius of the two cones are equal.
Slant height of one cone = 2 × Radius
Slant height of the other cone = 3 × Radius
Surface area of the shape = 57.8·π cm²
The curved surface area of a cone = π·r·l
Required:
The radius of the cone.
Solution;
Surface areas of the cones are therefore;
π·r × 2·r, and π·r × 3·r
The total surface area is therefore;
π·r × 2·r + π·r × 3·r = 57.8·π
5·r²·π = 57.8·π
Which gives;
r² = 57.8 ÷ 5 = 11.56
r = √(11.56) = 3.4
The radius of the cones, r = 3.4 cmLearn more about finding the surface area of 3-D shapes here:

how to calculate 13C2
Answer:
13C2 = 78
Step-by-step explanation:
Formula
[tex]nCr=\dfrac{n!}{r!(n-r)!}[/tex]
The ! symbol in math is called "factorial". When placed after a number, it means to multiply the number by every natural number below it.
For 13C2:
n = 13r = 2Substitute these values into the formula:
[tex]13C2=\dfrac{13!}{2!(13-2)!}[/tex]
[tex]=\dfrac{13!}{2! \ 11!}[/tex]
[tex]=\dfrac{13 \times 12 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 }{2 \times 1 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}[/tex]
[tex]=\dfrac{13 \times 12}{2 \times 1}[/tex]

The width of DNA is approximately 0.0000000025 meters wide. What is 6 times the width of DNA in Scientific notation
Answer:
Well "0.0000000025 x 6" is "1.5e-8" but
Step-by-step explanation:
Sadly I can't explain anything, It's just not one of my skills :(
The 6 times the width of DNA in Scientific notation will be 1.5 × 10⁻⁸.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The width of DNA is approximately 0.0000000025 meters wide.
The 6 times the width of DNA in Scientific notation will be given as,
⇒ 6 × 0.0000000025
⇒ 6 × 2.5 × 10⁻⁹
⇒ 1.5 × 10⁻⁸
The 6 times the width of DNA in Scientific notation will be 1.5 × 10⁻⁸.

Chase is constructing equilateral triangle EFG inscribed in a circle.
He begins by using a compass to draw circle X. He then uses a straightedge to draw a diameter of the circle and labels the endpoints D and E.
How can Chase find points Fand G?
OA.
Points Fand G are endpoints of a chord that is perpendicular to and bisects DE.
OB.
Points F and G are the points where circle X intersects a congruent circle centered at D.
O c.
Points Fand G are the points where circle X intersects a congruent circle centered at E.
OD
Points F and G are points of intersection of two congruent circles centered at D and E.
In the construction of the equilateral triangle EFG inscribed in a circle, Chase can find points F and G as D. Points F and G are points of intersection of two congruent circles centered at D and E.
What is an equilateral triangle?It should be noted that an equilateral triangle simply means a triangle that has all the sides and angles to be equal.
After drawing the diameter of the circle through the center, it's important to open the compass to a width that's equivalent to the radius the circle.
In this case, it can be deduced that Points F and G are points of intersection of two congruent circles centered at D and E.

A professor of statistics noticed that the marks in his course are normally distributed. He also noticed that his morning classes average 71% with a standard deviation of 12% on their final exams. His afternoon classes average 78% with a standard deviation of 8%. A. What is the probability that a randomly selected student in the morning class has a higher final exam mark than a randomly selected student from an afternoon class? Probability = B. What is the probability that the mean mark of four randomly selected students from a morning class is greater than the average mark of four randomly selected students from an afternoon class? Probability =
Answer:
0.3137 ; 0.2228
Step-by-step explanation:
Given a normal distribution :
Morning class :
Mean(Mm) = 71%
Standard deviation (Sm) = 12%
Afternoon class:
Mean(Ma) = 78%
Standard deviation (Sa) = 8%
M = Mm - Ma = (71 - 78) = - m7
S = √Sm + Sa = √12² + 8² = √208
A. What is the probability that a randomly selected student in the morning class has a higher final exam mark than a randomly selected student from an afternoon class?
P(morning > afternoon) = p(morning - afternoon > 0)
Using:
Z = (0 - (-7)) / S
Z = 7 / √208
Z = 0.4853628
P(Z > 0.49) = 0.3137
B)
What is the probability that the mean mark of four randomly selected students from a morning class is greater than the average mark of four randomly selected students from an afternoon class?
Using:
Z = (4 - (-7)) / S
Z = 11 / √208
Z = 0.7627127
P(Z > 0.49) = 0.2228
