HELP PLZ ...........WITH ALL OF THEM
Setler79 [48]

Answer:

1/2

Step-by-step explanation:

We first find the least common multiple, which is 6. Therefore, we can multiply 1/3 x 2/2 (since 2/2 is equal to one and won't change the final amount) and get 2/6. 2/6+1/6=3/6, or 1/2.

Change 2 21/9 to an improper fraction
ivanzaharov [21]

Answer: 13/3

Step-by-step explanation: TO turn a mixed number into an improper fraction, the best way is to multiply the denominator of the fraction by the whole number, then add the product to the numerator, then use that as the numerator of your new improper fraction, keeping the denominator the same.

>2 21/9

> 9*2 +21 =39

> 39/9

>13/3

A boat heads north across a river at a rate of 2 miles per hour. If the current is flow A boat heads north across a river at a r
Ivahew [28]

Answer:

\textrm{Resultant velocity}\ =\ \sqrt{29}\ miles/hour

along the direction 68.19° from north.

Step-by-step explanation:

Given,

  • speed of the boat, u= 2 miles/hour along north
  • speed of the river, v= 5 miles/ hour along east

Since, north and east are perpendicular to each other, so we can write the resultant velocity in vector form as,

\vec{r}\ =\ 2\hat{i}+5\hat{j}

Hence, the magnitude of resultant velocity can be written as

r\ =\ \sqrt{2^2+5^2}

  =\ \sqrt{4+25}

  =\ \sqrt{29}

Hence, the magnitude of resultant vector is \sqrt{29} moles/hour.

And the direction of the boat can be given by,

tan\theta\ =\ \dfrac{5}{2}

=>\ tan\theta\ =\ 2.5

=>\ \theta\ =\ tan^{-1}2.5

                 = 68.19°

Hence, the resultant velocity of boat is \sqrt{29} miles/hour along the direction making an angle 68.19° with the north.
