The area of a room is roughly 9∗10^4 square inches. If a person needs a minimum of 2.4∗10^3 square inches of space, what is the

valentina_108 [34]

Answer:

The maximum number of people who could fit in this room is 37

Step-by-step explanation:

Given;

The area of a room A = 9 × 10^4 square inches

Minimum Area needed per person M = 2.4×10^4 square inches

The maximum number of people who could fit in this room is;

N = The area of a room A/Minimum Area needed per person M

N = A/M

Substituting the values;

N = 9×10^4 ÷ 2.4×10^3

N = 37.5

Since we can not have a 0.5 person, the number would be approximated down to nearest lower whole number.

N = 37

The maximum number of people who could fit in this room is 37

What is the equation of the line that passes through the points (-2, 2) and (0, 5)?

Inessa [10]

Greetings!

We can use these points to find the slope of a line, using the slope formula: $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Input the points:
$m= \frac{(5)-(2)}{(0)-(-2)}$

Combine like terms:
$m= \frac{3}{2}$

The Slope is Equal to:
$\boxed{\frac{3}{2}}$

To find the y-intercept of the line, we use the slope and the points. First, arrange the equation is slope y-intercept form:
$y=mx+b$

Input the slope and one of the points:
$(5)=\frac{3}{2}(0)+b$

Combine like terms:
$(5)=b$

The y-intercept is Equal to:
$\boxed{5}$

The Equation of the Line Is:
$\boxed{y=\frac{3}{2}x+5}$

I hope this helped!
