Answer:

2: For every gallon of gas purchased, $3.75 was paid.

Step-by-step explanation:

Both options 1 and 3 would require having a dot plotted at those points to be sure, and they're close but they're still approximations. And option 4 is irrelevant. However the point at (4,15) can be used to check option two: 15/4 = 3.75 , ie the price per gallon of gas.

Find the distance between the two points rounding to the nearest tenth (if necessary). (-7, -5)(-3, 4)

aleksklad [387]

Answer:

9.8 ( to the nearest tenth )

Step-by-step explanation:

calculate the distance using the distance formula

d = √( x₂ - x₁ )² + ( y₂ - y₁ )²

with (x₁, y₁ ) = (- 7, - 5) and (x₂, y₂ ) = (- 3, 4)

d = $\sqrt{(-3+7)^2+(4+5)^2}$ = $\sqrt{16+81}$ = $\sqrt{97}$ = 9.8

Complete the data set with one value so that the mean of the data is 13.<br><br> 10,14,8,16,12,____

Allisa [31]

(10 + 14 + 8 + 16 + 12 + x ) /6 = 13
(60 + x) / 6 = 13
60 + x = 13 * 6
60 + x = 78
x = 78 - 60
x = 18 <=====

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 $6.25\pi\ in^{2}$

so

by proportion

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

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