Answer:

Step-by-step explanation:

5 + 3² · 5

The exponents come first, then the multiplication, then the addition:

5 + 9 · 5 = 5 + 45 = 50

Answer:

5, 7 , 7 and 11.

Step-by-step explanation:

I don't quite understand the Romanian but I'm pretty sure you want to find the numbers whose Lowest Common Multiple is 385 and whose product is 2695. Find the factors of 2695:-

5 2695

7 539

7 77

2695 = 5*7*7*11.

Lowest common multiple = 5*7*11 = 385.

Entomologists have discovered that a linear relationship exists between the rate of chirping of crickets of a certain species an

vekshin1

Answer:

a) $y=4x-160$

b) $y=4(102)-160=248\frac{chirps}{min}$

Step-by-step explanation:

We know that theres a linear relationship between the rate of the chirping of crickets and the air temperature.

The equation of a line is:

$y=mx+b$

So, let's name our variables

x= Temperature

y=Rate of the chirping

First of all, we need to find the slope with the two given points

$x_{1}=$ 60ºF , $y_{1} =80\frac{chirps}{min}$

$x_{2} =$ 80ºF, $y_{2} =160\frac{chirps}{min}$

By,

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} } =\frac{160-80}{80-60}$

$m=4$

Now, the equation between the air temperature and the number of chirps is:

$y-y_{1} =m(x-x_{1} )$

$y-80=4(x-60)$

Solving for y,

a) $y=4x-160$

b) To calculate the rate at which the crickets chirp when the temperature is 102 ºF we need to evaluate y(102)

$y=4(102)-160=248\frac{chirps}{min}$
