A circle has an area of 1.3 mi2. If a sector of the circle has an area of 0.7 mi2, what is the measure of the central angle in r

OleMash [197]

Answer:

area of circle=πr²=1.3mi²

we have

area of sector=∅/360×πr²

0.7mi²×360=∅1.3

∅=0.7×360/1.3=193.846°×π/180=387.7 radian

The speed of an elevator varies inversely with the weight it carries. If the elevator rises at 10 feet per second when it carrie

777dan777 [17]

Answer:

$8\frac{ft}{sec}$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

x-----> the speed of the elevator

y----> the weight it carries

$y*x=k$

Find the constant k

For x=10 ft/sec, y=400 lb

substitute

$k=10*400=4,000$

The equation is

$y*x=4,000$

Find the speed for y=500 lb

substitute in the equation

$500*x=4,000$

$x=4,000/500=8\frac{ft}{sec}$

Enter the slope-intercept equation of the line that has the same slope as y - 3 = (x + 3) and contains

mario62 [17]

Given:

$y-3=\frac{1}{2}(x+3)$

Point = (8, 4)

To find:

The slope-intercept form of the equation of the line.

Solution:

$$y-3=\frac{1}{2}(x+3)$

Slope of this line = $\frac{1}{2}$ .

Slope of the line is same as the slope of $y-3=\frac{1}{2}(x+3)$ .

Slope of the line (m) = $\frac{1}{2}$

General form of line:

y = mx + b

$y=\frac{1}{2} x+b$ ---------- (1)

It contains the point (8, 4). Substitute x = 8 and y = 4 in (1).

$4=\frac{1}{2}( 8)+b$

$4=4+b$

Subtract 4 from both sides, we get

b = 0

Substitute b = 0 in (1).

Equation of the line:

$y=\frac{1}{2} x+0$

$$y=\frac{1}{2} x$

Complete the sentence:

$y=\frac{1}{2} x$ ; I used the general form of a line in slope-intercept form, y = mx + b. The slope, m is $\frac{1}{2}$ . Then I substituted 8 for x and 4 for y into the standard form and solved for b, which is 0.
