Answer:

Option D

Step-by-step explanation:

We have to perform the indicated operation.

Given expression is \frac{a}{7}\times\frac{b}{2}

\frac{a\times b}{7\times 2}     [since \frac{x}{y}\times \frac{m}{n}=\frac{mx}{ny} ]

⇒ \frac{ab}{14}

Option D is the answer.

3 + 11 . (8 - 4) ÷ (5 + 6) - 4
Irina-Kira [14]

Answer:

3

Step-by-step explanation:

3 + 11 ⋅ ( 8 − 4 ) ÷ ( 5 + 6 ) − 4

 Subtract  4  from  8 .

3 + 11 ⋅ 4 ÷ ( 5 + 6 ) − 4

Multiply  11  by  4 .

3 + 44 ÷ ( 5 + 6 ) − 4

Find the common denominator.  

Add  5  and  6 .

3 + 44 ÷ 11 − 4

Write  3  as a fraction with denominator  1 .

3/ 1 + 44 ÷ 11 − 4

Multiply  3/ 1  by  11/ 11 .

3/ 1 ⋅ 11 /11 + 44 ÷ 11 − 4

Multiply  3/ 1  and  11 /11 .

3 ⋅ 11 /11 + 44 ÷ 11 − 4

Write  − 4  as a fraction with denominator  1 .

3 ⋅ 11 /11 + 44 ÷ 11 +  − 4 /1

Multiply  − 4 /1  by  11 /11 .

3 ⋅ 11 /11 + 44 ÷ 11 + − 4 /1  ⋅ 11 /11

Multiply  

− 4 /1  and  11 /11 .

3 ⋅ 11 /11 + 44 ÷ 11 +   − 4 ⋅ 11 /11

Combine the numerators over the common denominator.

3 ⋅ 11 + 44 − 4 ⋅ 11 /11

Simplify each term.  

Multiply  3  by  11 .

33 + 44 − 44 ⋅ 11/ 11

Multiply  − 4  by  11 .

33 + 44 − 44 /11

Simplify the expression.  

Add  33  and  44 .

77 − 44/ 11

Subtract  44  from  77 .

33 /11

Divide  33 by  11 .

What number has 7 ten thousands, 1 thousand, 1 hundred, and no ones?
FrozenT [24]

Answer:

71,100

Step-by-step explanation:

If you are trying to find a number that is written in word form, we can just use place values to find what goes where.

A number is broken down into this:

Ten thousands, thousands, hundreds, tens, ones.

If they have 7 ten thousands, the first digit will be a 7.

If they have 1 thousand, the second digit will be a 1.

If they have 1 hundred, the third digit will be a 1.

Since nothing is stated about tens, we assume it's value is 0.

And since there are no ones, it's value is 0.

So:

71,100.

Hope this helped!

BC = 6, EF = 12 Based on the given information, choose the similarity statement that you would use to say ABC~DEF. If you could
vovangra [49]

Answer:

The answer is "NOT"

Step-by-step explanation:

  • To demonstrate a similar statement we want to have yet another side or some other angle, however, the third section is not proportional.  
  • Its sides were equivalent in proportions (yeah sure they are) + corner by the by is not given.
  • There is no triangle angle provided so, that we can not enforce the SAS argument.  
  • It is not evidence of similarity between ABC ≈DEF.
