The expression 7•3x is not equal to the expression 21x. You might think that the two expressions are the same since 7x3 is 21 but the first expression is a dot product. This kind of expression includes the magnitude and direction of the vector in an expression, for example, <span>7•3x. The second expression, 21x, expresses only the magnitude and does not include the direction.</span>

What is 0.91 meter equal to 1 what?
telo118 [61]

Answer:2.986

Step-by-step explanation:

0.91 meter = 2.986 feet

Formula: multiply the value in meters by the conversion factor '3.2808398950132'.

So, 0.91 meter = 0.91 × 3.2808398950132 = 2.986 feet.

0.91 METER TO THE NEAREST FRACTIONS OR INTEGER OF FOOT:

3 feet (e* = 0.48%)

The latest values above are alternative ones for 0.91 meter. They are represented in the form of usable fractions (1

2

, 1

4

, 3

4

etc.) or of an integer. We show these results, when it is possible to convert them to a fraction or integer with a small error e* which means the maximum rounding error (positive or negative).

An angle measures 6 times the measure of its supplemantary angle. Find the measure of both angles
galben [10]

Answer:

<em>180/7 deg and 1080/7 deg</em>

Step-by-step explanation:

The measures of two supplementary angles add to 180 degrees.

One angle measures x.

The supplement measures 6x.

The sum of the measures is 180 deg.

x + 6x = 180

7x = 180

x = 180/7

6x = 1080/7
