The product of two number is 1575 and their quotient is 9/2 find the number

1 answer:

5 0

(1) p x q = 1575
(2) p / q = 9 / 2
divide 1 by 2 to eliminate p:
q^2 = 1575 / (9/2)
q^2 = 350
q = sqrt(350)

Substitue q in either 1 or 2 to find p.

The value of n such that the number n and -3/4 are additive inverses is 3/4

<h3>How to determine the value of n?</h3>

The statement is given as:

The number n and -3/4 are additive inverses

The above statement means that

n = -1 * -3/4 --- by the definition of additive inverses

Next, we evaluate the product of -1 and -3/4

n = 3/4

Hence, the value of n such that the number n and -3/4 are additive inverses is 3/4

Find the percent of discount for $70 discounted to $63. Round to the nearest percent.

aksik [14]

70 x P = 63
P=63/70 = 0.9
Since P is 1-the discount
1-discount= 0.9
discount is 0.1, or 10 %

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.
