Alex Ar [27]

Answer: He needs 20 hours for making 33 kg of meat.

Step-by-step explanation:

Since, if a a thing in quantity $x_1$ takes time $t_1$ and that thing in quantity $x_2$ takes time $t_2$

Then, we know that,

$x_1\times t_1=x_2\times t_2$

$\frac{x_1}{x_2} = \frac{t_2}{t_1}$

Here, $x_1=55$ kg, $t_1=12$ hours, $x_2= 33$ kg and $t_2=?$

Thus, $\frac{55}{33} = \frac{t_2}{12}$

⇒ $t_2=\frac{55}{33}\times 12$

⇒ $t_2=\frac{5}{3}\times 12$

⇒ $t_2=20$

Thus, he needs 20 hours to make 33 kg of meat.

Complete the following sentence. The slope of the graph of y = 5 x is ___

Y_Kistochka [10]

Answer:

We conclude that the slope of the graph of y = 5 x is 5.

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

where

m is the slope

b is the y-intercept

Given the line

y = 5x

comparing with the slope-intercept form of the line equation

The slope of the line = m = 5

Therefore, we conclude that the slope of the graph of y = 5 x is 5.

What is the trigonometric ratio for cos N?

bagirrra123 [75]

If we look at our SOHCAHTOA rule:
cos(x) = adj/hyp

The adjacent side of N is 36, and the hypotenuse is 39.

Therefore:
cos(N) = 36 / 39
