The area of a circle is 42 pi M squared. what is the area of a 60° sector of this circle​
andreev551 [17]

Answer:

7π M squared

Step-by-step explanation:

<em>Since a whole circle is 360°, and we need to find 60° of this circle, we are basically wanting to find  \frac{60}{360}=\frac{1}{6}th of the circle.</em>

<em />

Area is given as 42π M squared, so 1/6th of that is  \frac{1}{6}*42\pi\\=7\pi

THus, the area is 7π M squared

Write the equation of the line that passes through the points (1,6) and (3, -4)
gavmur [86]

Answer:

A. y = -5x + 11

Step-by-step explanation:

The general form of the equation of a line is given as

y - y1 = m (x - x1)

where m is the slope and x1, y1 are the coordinates of a point on the line.

m = (y2 - y1)/(x2 - x1)

Given the points (1,6) and (3, -4)

m = (-4-6)/(3-1)

=-10/2

= -5

The equation of the line will be

y - 6 = -5(x -1)

y - 6 = -5x + 5

Add 6 to both side

y = -5x + 5 + 6

y = -5x + 11

Option A

denis-greek [22]

Answer:

8.28%

Step-by-step explanation:

According to the U.S. Census Bureau, the legal official department in charge of the National Census every ten years, the population of the U.S.A in 2010 was<em> 308,745,538 inhabitants.</em>

If about 25,585,000 had diabetes, then <em>cross multiplying</em>

308,745,538-------100%

25,585,000---------x%

and

\frac{308,745,538}{25,585,000}=\frac{100}{x}

and so, about

x=\frac{25,585,000*100}{308,745,538}=8.28 \%

Americans had diabetes in 2010.
