steposvetlana [31]3 years ago
7 0

Answer:

The Correct option is A) 8

The value of a is 8.

Step-by-step explanation:

Vertical Angles:  

The angles opposite each other when two lines cross.

They are always equal.

∠ 2(3a-7)° and ∠ (5a-6)° are vertical angles.Hence are equal.

So on Substituting we get

2(3a-7)\°=(5a-6)\°

Applying distributive property we get

2\times 3a-2\times 7=5a-6\\6a-14=5a-6\\6a-5a=14-6\\\\\therefore a=8

The value of a is 8

The Correct option is A) 8

one positive number is 28 less than another number. if the reciprocal of the smaller number is added to four times the reciproca
marishachu [46]
Let x represent the larger number.
  1/(x -28) +4/x = 1/6
Multiplying by the product of denominators, we have
  6x +24(x -28) = x(x -28)
In standard form, this is
  x^2 -58x +672 = 0
  (x -42)(x -16) = 0

The two numbers are (-12 and 16) or (14 and 42).

For the algorithm below, compute the number of multiplications performed, as well as the final value of s. p ← 1 s ← 0 for i is
enot [183]
<span>p ← 1

s ← 0

for i is in {1, 2, 3, 4}
      do p ← p · 3
           s ← s + p

n = 1 => first iteration

               p = 1 * 3 = 3
               s = 0 + 3 = 3

number of multiplications ---> 1

n = 2
             p = 3 * 3 = 9
             s = 3 + 9 = 12

number of multiplications ----> 1 + 1 = 2

n = 3
            p = 9 * 3 = 27
            s = 12 + 27 = 39

number o multiplications --> 2 + 1 = 3

n = 4
            p = 27 * 7 = 81
            s = 39 + 81 = 120

final number of multiplications -----> 3 + 1 = 4

final value of s
                     s = 120

Answer: number of mujltiplications: 4
final value of s: s = 120.

Gwent pour 256 milliliters of water in to Ravi Henry pours 189 milliters of water in to Ravis .Ravis now contains 800 Milliters
Contact [7]

Answer:

Ravi had 355ml water to begin with.

Step-by-step explanation:

Given that,

amount of water that Gwent pour in Ravi = 256 ml

amount of water that Henry pour in Ravi = 189 ml

amount of water after each have poured = 800 ml

suppose amount of water ravi had before both poured water in it = x

Equation

256 + 189 + x = 800

445 + x = 800

x = 355ml

Initially ravi had 335ml of water.
