Answer:

Step-by-step explanation:

$2xy + 3xt - 7yt = 0$

$3xt - 7yt = - 2xy$

Factor out t

$t(3x - 7y) = - 2xy$

Divide by 3x-7y

$t = - \frac{2xy}{3x - 7y}$

But since x and y are positive, the answer is positive

$t = \frac{2xy}{3x - 7y}$

What is the longest line segment that can be drawn in a right rectangular prism that is 14 cm long 11 cm wide and 7 cm tall

weqwewe [10]

Answer:

The longest segment is approximately 19.13cm

Step-by-step explanation:

Given

$l = 14cm$

$w = 11cm$

$h = 7cm$

Required

The length of the longest segment (d)

This is calculated using:

$d = \sqrt{l^2 +w^2 + h^2$

So, we have:

$d = \sqrt{14^2 +11^2 +7^2$

Using a calculator, the equation becomes

$d = \sqrt{366$

Take square roots

$d = 19.13cm$

Suppose that y is directly proportional to x and that y = 10 when x = 3. Complete parts (a) and (b). (a) Find the constant of pr

Yuliya22 [10]

For this case we have that if "y" varies directly with "x", then it is true that:

$y = kx$

Where:

k: It is the constant of proportionality

We have according to the data that:

$10 = k (3)$

We find the value of "k":

$k = \frac {10} {3}$

Having "k", we find "y" when $x = 6$ :

$y = \frac {10} {3} (6)\\y = \frac {60} {3}\\y = 20$

ANswer:

$k = \frac {10} {3}\\y = 20$
