20, 21, 29

Explanation:
Use the Pythagorean Theorem
20^2 + 21^2 = 29^2
400 + 441= 841

Answer:

Step-by-step explanation:

Theres a ratio of 1:4

Where Jamie has driven 4 times as much as Rhonda

meaning that you can plug in values, 1:4=125

the 4 represents Jamie since she drove farther than rhonda

Rhonda drove 25 miles, and Jamie drove 100 miles

25(4)+25=124

I don’t know what I’m doing wrong. I need help understanding this problem please...

Answer:

Step-by-step explanation:

Cost (C) depends on the number of miles traveled (x).

So C is the dependent variable.

Or C(x) if they want you to be more specific.

x is your independent variable.

Miles driven do not depend on anything.

Please Help? A circle has an arc length of 5π in. The central angle for this arc measures π/3 radians. What is the area of the a

Zielflug [23.3K]

Answer:

The area of the associated sector is $\frac{25}{24}\pi \ in^{2}$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=5\pi\ in$

substitute and solve for r

$5\pi=2\pi r$

$r=2.5\ in$

step 2

Find the area of the circle

we know that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=2.5\ in$

substitute

$A=\pi (2.5^{2})=6.25\pi\ in^{2}$

step 3

Find the area of the associated sector

we know that

$2\pi\ radians$ subtends the complete circle of area $6.25\pi\ in^{2}$

by proportion

Find the area of a sector with a central angle of $\pi/3\ radians$

$\frac{6.25\pi }{2\pi} =\frac{x}{\pi/3}\\x=6.25*(\pi/3)/2\\ \\x=\frac{25}{24}\pi \ in^{2}$

1) Identify the slope of the given line

adell [148]

ok so here we go:

1) $(-6,-2.5),(-4,-3)\ m= -0.25$ or $-\frac{1}{4}$

2 ) $y=-0.25x-4$ so the answer is (0, -4) or -4

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

4) y=[tex]\frac{3}{2}x+1[tex] so the answer is (0, 1) or 1
