54. If a*b = a? – b3, then what is the value of 3*-2?
41. A bag contains 13 red marbles, 12 green marbles and 5 blue marbles. If you mix up the
marbles and pull one out at random, what is the probability that it will be blue? (Answer,
of course, as a fraction in lowest terms.)
48. The 14 letters in the words RHYMING COUPLET are written on separate cards and put
into a hat to be shuffled. You draw out two cards at random. What is the probability that
they show the same letter?
The probability of selecting blue is 1/6
There are no repeated letters, hence the probability that
they show the same letter is 0
Equation and probabilityProbability is the likelihood or chance that an event will occur, Mathematically;
Probability = Expected/Total
54) Given the expression a*b = a^3 – b^3
To calculate 3 * -2
3* -2 = 3^3 - (-2)^3
3* -2 = 27 - 8
3* -2 = 19
Hence the value of 3* -2 is 19
41) From the quation
Total outcome = 13 + 12 + 5
Total outcome = 30 marbles
Pr(picking blue) = 5/30 = 1/6
Hence the probability of selecting blue is 1/6
42) Since there are 14 letters, hence total outcome = 14
Pr(drawing out same letter ) = 0/14 = 0
Since there are no repeated letters, hence the probability that
they show the same letter is 0

3/8 plus 1/2
Fractions
Answer:
7/8
Step-by-step explanation:
To add the fractions, find the LCD and then combine.
Answer:
We have to make sure the denominators are equal.
Since 2 is evenly divided by 8, we can multiply just one term to get a common denominator.
Multiply 1 by 4, and get 4, then we multiply 2 by 4 and get 8.
x4
So you multply 1/2 4/8 (muliply numerator)
x4
1/2 x 4/8 (multiply denominator
now 3/8+4/8
since denominators match you can add
3+4=7 so its 7/8

Answer: 1661 cm^2
Step-by-step explanation:
The area of a circle is pi*radius^2.
The diameter is given as 46 cm and the radius is 1/2 of the diameter = 23 cm.
Therefore, the area of the circle is pi*23^2 = 529pi = about 1661 cm^2
========================================================
Explanation:
The diameter is 46 cm, which cuts in half to the radius of 23 cm.
area = pi*(radius)^2
A = pi*r^2
A = pi*23^2
A = pi*529
A = 529pi
This is the exact area in terms of pi.
--------
From here, replace pi with an approximation such as 3.14
529*pi = 529*3.14 = 1661.06
This value is approximate of course. To get a better approximation, use more decimal digits of pi.
This then rounds to 1661 square cm.

Answer:
0.800?
Step-by-step explanation:
i don't really know im just kinda guessing but would't it be right?
Answer:
56 degrees.
Step-by-step explanation:
It looks to me like they want you to find the original angle A and you need to use a scientific calculator unless you know advanced calculus. The arcsine or sine^-1 of 0.829 is approximately 56 degrees.
Given the vectors v=3i-2j and w=-i+5j, find v · w.
v * w = (3i - 2j) *(-i + 5j) = 3(-1) + (-2)(5) = -3 + -10 = -13
Hope that helps!
Answer:
v.w = -13
Step-by-step explanation:
v.w = (3i - 2j).(-i + 5j) = 3 × -1 × i.i + 3 × 5 × i.j + -2×-1 × j.i + -2×5 × j.j
i.i = j.j = 1 , i.j = j.i = 0
→
v.w = -3 - 10 = -13
Which equation does the graph of the system of equations solve?
A. 2x + 2 = x - 5
B. 2x + 2= -x + 5
C. 2x + 4 = x - 4
D. 2x + 3 = -x + 5
Answer:
B
Step-by-step explanation:
Equation of line 1:
Choose two points : (-1, 0) & (0,2)
y -intercept = b = 2
y = mx+ 2
Plugin the values of the points ( -1 , 0) in the above equation
0 = -1m + 2
-2 = -m
m = 2
Equation of line 1 : y = 2x + 2
Equation of line 2:
(5,0) & (0,5)
y-intercept = b = 5
y = mx +b
y = mx + 5
Plugin the value of points (5 , 0) in the above equation
0 = 5m + 5
-5 = 5m
-5/5 = m
m = -1
Equation of line 2: y = -x + 5
Conclusion: 2x + 2 = -x + 5

A grain silo with the shape of a right cylinder is to be filled with corn. The diameter of the silo is 14 feet and the height is 30 feet. Excluding the domed top, approximately how many cubic feet of corn will the silo hold? Use 3.14 for
π
The cubic feet of corn the cylinder silo will hold is 4615.8 ft³.
Volume of a cylinderv = πr²hwhere
r = radius
h = height
The grain silo is in the form of a right cylinder. Therefore,
diameter = 14 ft
radius = 14 / 2 = 7 ft
height = 30 ft
The cubic ft of corn that will contain the silo is the volume. Therefore,
v = 3.14 × 7² × 30
v = 3.14 × 49 × 30
v = 4615.8
v = 4615.8 ft³

Answer:
AC = √105 ≈ 10 cm (nearest whole number)
Step-by-step explanation:
Use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Give one of the legs = 4cm and the hypotenuse = 11 cm:
⇒ 4² + AC² = 11²
⇒ 16 + AC² = 121
⇒ AC² = 121 - 16
⇒ AC² = 105
⇒ AC = ±√105
As distance is positive, length of AC = √105 ≈ 10 cm (nearest whole number)
Step-by-step explanation:
AB²=BC²+CA²
(11)²=(4)²+ CA²
121=16 + CA²
121-16= CA²
105=CA²
√105=CA
10.2=CA

What is the length of the altitude of an equilateral triangle with sides of 8 square root 3?
Answer: In AMB: sin 60 = AMAB √(3)2 = ABa AB = √(3)a2
Step-by-step explanation: The altitude of a triangle is the perpendicular line segment drawn from the vertex to the opposite side of the triangle. It may lie inside or outside the triangle, based on the types of triangles. The altitude of a triangle basically defines the height, when we have to measure the area of a triangle, with respect to the base.
