Answer:
(32, 31) (33,30) (34, 29) (35, 28) (36,27) (37, 26)
Step-by-step explanation:
The pairs of whole numbers that add to 63 and have a difference less than 10 are (27, 36), (28, 35), (29, 34), (30, 33), and (31, 32).
This problem is based in the domain of basic algebra. Essentially, you are being asked to find pairs of whole numbers that, added together, equal 63, with the condition that the difference between these two numbers is less than 10.
Starting from the number 32 (as any larger number plus any number greater than 0 would exceed 63), you can begin to list pairs, subtracting one number from the total of 63 while simultaneously adding that same amount to the other half of the pair. This will ensure that the sum always equals 63.
Here are the pairs satisfying the given conditions: (27, 36), (28, 35), (29, 34), (30, 33), (31, 32). For these pairs, the difference between the two numbers in each pair is less than 10.

The Law of Sines tells you
... sin(C)/c = sin(A)/a
... sin(C) = c·sin(A)/a . . . . multiply by c
... C = arcsin(c·sin(A)/a) . . take the inverse sine
Then
... sin(B)/b = sin(A)/a . . . . law of sines again
... b = a·sin(B)/sin(A) . . . . multiply by a·b/sin(A)
where B = 180° - A - C = 160° - C . . . . . . sum of angles in a triangle is 180°
Filling in the given values, we get
... C = arcsin(5.4·sin(20°)/3.3) ≈ 34.033° or 145.967°
Then
... B = 125.967° or 14.033°
and
... b = 3.3/sin(20°)·sin(125.967°) or 3.3/sin(20°)·sin(14.033°)
... b = 7.8 or 2.3 . . . units
The appropriate choice is
... 2.3 units and 7.8 units
Answer:
C)2.3 units and 7.8 units

Answer:
X + 1/2X + 1/5(1/2X) = 1,600,000
Step-by-step explanation:
Si se plantea que en una herencia de $1,600,000, la primer hermana recibirá un monto de dinero indeterminado, mientras que la segunda recibirá un medio del valor que reciba la primera, y la segunda recibirá un quinto de lo que reciba la segunda, la ecuación que visualiza dicha situación es la siguiente:
X + 1/2X + 1/5(1/2X) = 1,600,000
X + 1/2X + 1/10X = 1,600,000
10X + 5X + X = 16,000,000
16X = 16,000,000
X = 16,000,000 / 16
X = 1,000,000
Así, la primer hermana recibirá $1,000,000, la segunda $500,000, y la tercera $100,000.
Answer:
20 and 90
Step-by-step explanation:
20 + 2(90) = 200
20 + 180 = 200
200 = 200
20 × 2(90)
= 20× 180
= 3,600
