What is1\7 the speed of a cheetah?

Answers

1/7 the speed of a cheetah is 10 mph because an average cheetah can run 70 miles per hour. This means time to do some division. Envision the denominator of 1/7 (7) as 70 and then the numerator (1) should be 10. Divide 70 by 7 should be 10. Hope this helps.

Since the speed of the cheata is93 k then that 1/7 of that is 13and 2/7. Hope this helped :)

Step-by-step explanation:

3.1 × 22 + 6 ÷ 2 - (3.9 + 3.3)

Answers

$\sf3.1*22+6/2-(3.9+3.3)$

PEMDAS, parenthesis first:

$\sf3.1*22+6/2-7.2$

Now multiply:

$\sf68.2+6/2-7.2$

Divide:

$\sf68.2+3-7.2$

Add:

$\sf71.2-7.2$

Subtract:

$\sf64$

You have to use PEMDAS which is Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. The answer would be 29.9.

What is the value of 2x{6+[12/(3+1)}-1

Answers

The value of an expression is calculated by simplifying the expression.

The value of the expression is 17

The expression is given as:

$\mathbf{2 * \{6+[12 / (3+1)\}-1}$

Simplify 3 + 1

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+[12 / 4\}-1}$

Divide

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+[3\}-1}$

Remove square bracket

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+3\}-1}$

Add

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{9\}-1}$

Remove curly bracket

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * 9-1}$

Multiply

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 18-1}$

Subtract

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 17}$

Hence, the value of the expression is 17
