S=4

Explanation
Subtract 4 from both sides
19=3s+4 -> 15=3s
Then divide both sides by 3, allowing the s to be isolated.
15=3s divide by 3 -> 5=s

Find the arc length and area of a sector with radius R =60 inches and central angle equals 30° round your answer to the nearest

Black_prince [1.1K]

Answer:

(a)31.42 inches

(b)942.48 Square Inches

Step-by-step explanation:

Given a sector of a circle with the following dimensions:

Radius of the circle =60 inches

Central Angle of the sector =30°

(a)Arc Length

Arc Length $=\dfrac{\theta}{360^\circ}X2\pi r$

$=\dfrac{30}{360^\circ}X2*60*\pi\\\\=10\pi\\\\=31.42$ Inches (correct to the nearest hundredth)$

(b)Area of the sector

Area of the sector $=\dfrac{\theta}{360^\circ}X\pi r^2$

$=\dfrac{30}{360^\circ}X\pi*60^2\\\\=300\pi\\\\=942.48$ Square Inches (correct to the nearest hundredth)$

PLEASE HELP BRAINLY - which option is correct?

LuckyWell [14K]

Answer:

$y > \frac{2x}{3} + 1$

Step-by-step explanation:

Given:

The graph in the attachment where the coordinates are (3,3) and (-3,-1)

Required:

Which inequality represent the graph

The first step is to determine the slope of the graph

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where m represents the slope, $(x_1, y_1) = (3,3)$ and $(x_2, y_2) = (-3,-1)$

$m = \frac{-1 - 3}{-3 - 3}$

$m = \frac{-4}{-6}$

Simplify to lowest term

$m = \frac{2}{3}$

Next is to determine the equation of the line using the slope formula

$m = \frac{y - y_1}{x - x_1}$ , $(x_1, y_1) = (3,3)$ and $m = \frac{2}{3}$

$\frac{2}{3} = \frac{y - 3}{x - 3}$

Cross multiply

$2 * (x - 3) = 3 * (y - 3)$

Open both brackets

$2 x - 6 = 3y -9$

Collect like terms

$2 x - 6 +9= 3y$

$2 x+3= 3y$

Divide through by 3

$\frac{2x}{3} + \frac{3}{3} = \frac{3y}{3}$

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

Reorder

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

Next is to determine the inequality sign

The dotted lines on the graph shows that the inequality sign is either > or <
Since the shaded region is the upper part of the graph, then the > inequality sign will be considered,

The inequality becomes

$y > \frac{2x}{3} + 1$

Target sells AAA batteries for $1.10 and AA batteries for $0.50. They sold 350 total batteries earning a total of $560. How many

satela [25.4K]

Answer:

This is not possible because the selling of number of AA batteries cannot be negative.

Step-by-step explanation:

Let us assume that the number of AAA batteries sells be x .

Let us assume that the number of AA batteries sells be y.

As given

Target sells AAA batteries for $1.10 and AA batteries for $0.50. They sold 350 total batteries earning a total of $560.

Equations becomes

x + y = 350

1.10x + 0.50y = 560

Simplify the above equation

$\frac{110x}{100} + \frac{50y}{100} = 560$

110x + 50y = 56000

Two equations becomes

x + y = 350

110x + 50y = 56000

Multiply x + y = 350 by 50 and subtracted from 110x + 50y = 56000 .

110x - 50x + 50y - 50y = 56000 - 17500

60x = 38500

$x = \frac{38500}{60}$

x = 641 .6 (Approx)

Put this value in the equation x + y = 350 .

641.6 + y = 350

y = 350 - 641.6

y = -291.6

This is not possible because the selling of number of AA batteries cannot be negative.
