Joe says 4.02 x 0.3 is bout 12. Does this make sense? Explain your thinking

2 answers:

Think: 4.02 is about 4 and 0.3 is about 1/3. 4 times 1/3 is 4/3, or about 1.33. So 12 is 'way off. It's always wise to estimate what your answer should look like.

This does not make sense as you are multiplying 4.02 by a number less that 1, so the product will become smaller. By actual calculation, this will be 1.206. Hope this helps.

Using the segment addition postulate, which is true? What is the measure of AngleDCF? Three lines extend from point C. The space

Flura [38]

Answer:

129

Step-by-step explanation:

If three lines CD, CE and CF extend from point C, then the following addition postulate is true;

<DCE + <ECF = <DCF

If the space between line C D and C E is 75 degrees, then <DCE = 75

If the space between lines C E and C F is 54, then <ECF = 54.

Substitute the given values into the expression above will give;

<DCF =<DCE + <ECF

<DCF = 75+54

<DCF = 129

Hence the measure of <DCF is 129°

What is the coefficient of (-2/3x)(3y)(-2x)

dolphi86 [110]

Answer:

The coefficient is equal to $4$

Step-by-step explanation:

we have

$(-\frac{2}{3}x)(3y)(-2x)$

we know that

The coefficient is equal to

$(-\frac{2}{3})(3)(-2)=4$

$(-\frac{2}{3}x)(3y)(-2x)=4x^{2}y$

<h3>What is the decimal?</h3>

A rational number is a number that can be expressed as a fraction of two integers.

A decimal is a non-integer in which the integers are separated from the non integers by a point. In order to convert the fraction to a decimal, divide the numerator by the denominator.

5/7 = 0.714
