3 plus 5 equals 4times b therefore b equals?
3 + 5 = 4*b so 8 = 4*b Divide both sides by 4: 2 = b
How many different hands of poker can you make with 7 cards?
There are 20 unique 5-card hands. Solution: First break apart the player card combinations. You can either use player card 1, player card 2, or both player cards 1 and 2 with the hand. Therefore, you are taking 5 cards, 3 at a time, when playing with both player cards, and 5 cards, 4 at a time, when playing with 1 player card. Mathematically, this can be expressed using the Binomial coefficient 2 x ( 5 choose 4 ) + ( 5 choose 3 ) = Number of possible 5-card hands. 5 choose 4 = 5 : This represents the combinations between 1 player card and 5 table cards, 4 at a time. (http://www.wolframalpha.com/input/?i=5+choose+4) 5 choose 3 = 10 : This represents the combinations between 2 player cards, and 5 table cards, 3 at a time. (http://www.wolframalpha.com/input/?i=5+choose+3) Thus, 2 x ( 5 ) + ( 10 ) = 20 . Further Information: All possible hand combinations are listed below. A and B are the two player cards. 0 through 5 are the five table cards. ----- A 1 2 3 4 A 2 3 4 5 A 3 4 5 1 A 4 5 1 2 A 5 1 2 3 B 1 2 3 4 B 2 3 4 5 B 3 4 5 1 B 4 5 1 2 B 5 1 2 3 A B 2 3 4 A B 3 4 5 A B 1 2 3 A B 4 5 1 A B 5 1 2 A B 4 5 2 A B 4 1 2 A B 5 1 3 A B 5 2 3 A B 1 3 5
What is the formula for factoring the difference of two numbers each to the power of seven?
a^7 - b^7 = (a - b)(a^6 + a^5.b + a^4.b^2 + a^3.b^3 + a^2.b^4 +a.b^5 + b^6)
If x 4 and y 3 then 5x 8y?
(5*4)+(8*3) where *indicates to multiply, and the equations in parenthesis(5*4 and 8*3) are done before you add them, so 5*4=A, 8*3=B, then A+B. Not doing your homework for you. AND USE THE COMPUTER CALCULATOR!!
When you multiply a negative number by a positive number what happens explain?
Multiplication is an abbreviation of addition: 4 x 5 is the same as: adding 4 together 5 times: 4 x 5 = 4 + 4 + 4 + 4 + 4 = 20; or adding 5 together 4 times: 4 x 5 = 5 + 5 + 5 + 5 = 20 When multiplying a negative number by a positive number, it can be thought of adding the negative number to itself the positive number of times. eg -4 x 5 = -4 + -4 + -4 + -4 + -4 = -20 eg -5 x 4 = -5 + -5 + -5 + -5 = -20 Adding a negative number is the same as subtracting the number (as a positive number): eg 7 + -3 = 7 - 3 = 4 eg -7 + -3 = -7 - 3 = -10
3 plus 5 equals 4times b therefore b equals?
3 + 5 = 4*b so 8 = 4*b Divide both sides by 4: 2 = b

What is the area of a quadrilateral with vertices at -4 3 and -4 5 and 3 5 and 5 3?
Inspection of the coordinates (by drawing a sketch) shows that the quadrilateral is a right trapezium with the parallel sides (a, b) horizontal. Let A = (-4, 3), B = (-4, 5), C = (3, 5), D = (5, 3) area trapezium = ½ × (a + b) × h = ½ × (BC + AD) × AB = ½ × ((3 - -4) + (5 - -4)) × (5 - 3) = ½ × (7 + 9) × 2 = 16 square units.
What is the sin of angle B if the angles are 3 4 5?
I think you have not asked the question correctly.I guess you meant that the sides of the triangle are 3, 4 and 5. Similarly you have given no indication of which angle is opposite which side.A 3, 4, 5 triangle is a right angle triangle (5 is the hypotenuse).Thus depending where angle B is, its sine will be:If B is opposite the side of length 3, sin B = 4/5If B is opposite the side of length 4, sin B = 3/5If B is opposite the side of length 5, sin B = 5/5 = 1; alternatively ∠B = 90° and sin B = sin 90° = 1

If you have a 10 measuring cup 4 measuring cup and a 3 measuring cup how many pours does it take to get the 4 to 4 the 3 to 1 and the 10 to half?
Assuming the 10 = Cup A, 4 = Cup B and 3 = Cup C 1) Fill Cup C (A=0, B=0, C=3) 2) Pour Cup C into Cup A (A=3, B=0, C=0) 3) Fill Cup B (A=3, B=4, C=0) 4) Fill Cup C from Cup A (A=3, B=1, C=3) 5) Pour the remainder of Cup B into Cup A (A=4, B=0, C=3) 6) Empty Cup C (A=4, B=0, C=0) 7) Fill Cup B (A=4, B=4, C=0) 8) Fill Cup C from Cup A (A=4, B=1, C=3) 9) Pour the remainder of Cup B into Cup A (A=5, B=0, C=3) 10) Empty Cup C (A=5, B=0, C=0) 11) Fill Cup B (A=5, B=4, C=0) 12) Fill Cup C from Cup A (A=5, B=1, C=3) 13) Empty Cup C (A=5, B=1, C=0) 13) Pour the remainder of Cup B into Cup C (A=5, B=0, C=1) 14) Fill Cup B (A=5, B=4, C=1) so assuming you count the filling of cups as pours your answer is 14

the ratio of A to B is 2:3 and the ratio of B to C is 4:5. what is the ratio of A to C?
Oh, what a happy little problem we have here! To find the ratio of A to C, we can simply multiply the two ratios together. So, 2:3 times 4:5 gives us 8:15. That's the beautiful ratio of A to C, just like painting a lovely landscape with different colors blending harmoniously together.
