Answer:

Step-by-step explanation:

The area of a sector has the formula

$A_s=\frac{\theta}{360}*\pi r^2$ Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:

$A_s=\frac{75}{360}*(3.14)(4)^2$ and simplifying that a bit to look less threatening, but not by much:

$A_s=\frac{5}{24}(3.14)(16)$ and

$A_s=\frac{251.2}{24}=\frac{157}{15}=10.466666666...$ Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.

Which best describes the graph of the function f(x)=4x ?

Answer:

Step-by-step explanation:

The equation of a line in slope-intercept form is

y = mx + b

where m = slope, and b = y-intercept.

This line has equation

y = 4x

When we compare y = 4x with y = mx + b, we see that m = 4, and b = 0.

This line intersects the y-axis (the y-intercept) at y = 0, which is the origin. The slope is positive, so it slopes up to the right.

How many houses have an area less than 100 m² ?

dsp73

Answer:

This question overall depends on a continuously changing factor.

Step-by-step explanation:

There are many houses in this world that have an area of less than 100 $m^2$ , while many others have up to 700, 800, or even 1000 $m^2$ of land. Your question is impossible to calculate because of the massive amount of houses in this world. If you want a good estimate, say around 0.9 to 1.8 billion.
