4 0

Answer:

a_{10} = \frac{5}{8}

Step-by-step explanation:

The n th term of a geometric sequence is

a_{n} = a_{1} r^{n-1}

Substitute in values

a_{10} = 320 × (\frac{1}{2}) ^{9}

                         = 320 × \frac{1}{512} = \frac{320}{512} = \frac{5}{8} = 0.625

300-7[4(3+5)]+3 to the 3rd power
Mila [183]

Answer:

The answer is 103

Step-by-step explanation:

The given expression is:

300-7[4(3+5)]+3 to the 3rd power

3 to the 3rd power means 3^3

Therefore,

300-7[4(3+5)]+3^3

First we will solve the round bracket and find the cube

300-7[4(8)]+27

Now we will solve square bracket

300-7[32]+ 27

300-224+27

76+27

103

Thus the answer we get is 103....

1/7 divided by blank equals 14
kherson [118]

Answer:

1/98

Step-by-step explanation:

Step 1: Translate statement into equation.

  • \frac{1}{7}/x = 14
  • \frac{1}{7x}=14

Step 2: Multiply both sides by 7x.

  • \frac{1}{7x} * 7x = 14 * 7x
  • 1 = 98x

Step 3: Divide both sides by 98.

  • \frac{1}{98} =\frac{98x}{98}
  • x = \frac{1}{98}

Step 4: Check if solution is correct.

  • \frac{1}{7}/\frac{1}{98}
  • \frac{1}{7}*98
  • 14

Therefore, the answer is 1/98.
