Take a look at the two points (0,6) and (4,0). The slope of the line connecting these two points is negative. The slope is -6/4, or -3/2.

Using the point-slope equation of a straight line, the equation applying here is

y - 0 = (-3/2)(x - 4), or y = (-3/2)x + 6

Answer: 13.96 in²

Step-by-step explanation:

radius (r)

d = 2r

16 = 2r

8 = r

angle in radians (θ)

$\frac{180}{\pi} =\frac{25}{\theta}$

180(θ) = 25(π)

θ = $\frac{25}{180}\pi$

θ = $\frac{5}{36}\pi$

Area (A)

A = $\frac{1}{2}$ r² θ

= $\frac{1}{2}(8)^{2}(\frac{5}{36}\pi)$

= $\frac{40}{9}\pi$

= 13.96

Answer: 12π

Step-by-step explanation:

s = rθ

= 60 $(\frac{\pi }{5})$

= 12π

Answer: 22.440 cm²

Step-by-step explanation:

A = $\frac{1}{2}$ r²θ

= $\frac{1}{2}$ (10)² $(\frac{\pi} {7})$

= $\frac{50}{7}\pi$

= 22.440

Answer: 270°, 630°, -450°, -810°

Step-by-step explanation:

positive: -90 + 360 = 270

270 + 360 = 630

negative: -90 - 360 = -450

-450 - 360 = -810

Answer: $\frac{3\pi} {4}$

Step-by-step explanation:

$\frac{19\pi} {4} - 2\pi$

= $\frac{19\pi} {4} - \frac{8\pi} {4}$

= $\frac{11\pi} {4}$

$\frac{11\pi}{4} - 2\pi$

= $\frac{11\pi} {4} - \frac{8\pi} {4}$

= $\frac{3\pi} {4}$

If you subtract another 2π, you will end up with a negative value. The question asks for the smallest positive value.

A fair owner made 18 dollars when a group of three entered which is the rate of fair per person

Masteriza [31]

Let's start with an example.

At the market, 8 batteries cost $10.

How much do 6 batteries cost?

We’re trying to find the cost of 6 batteries.

Batteries Cost

8 / 8 = 1 $10/ 8 = $1.25

If 8 batteries cost $10, then 11 battery costs $1.25.

Batteries Cost

8 $10

1 x 6 $1.25 x 6

6 $7.50

So, 6 batteries cost $7.50.

Back to your question...

We are trying to find the rate of fair which means the fair price for 1 person

Fair Person

18/3 3/3

6 1

So, the fair owner will make $6 for 1 person.

Hope this helped! Good luck!

3(a - 4) ≤ 33 Help me solve

yaroslaw [1]

Answer:

a ≤ 15

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

3(a - 4) ≤ 33

Step 2: Solve for a

Divide 3 on both sides: a - 4 ≤ 11
Add 4 on both sides: a ≤ 15

Here we see that any value a less than or equal to 15 would work as a solution to the inequality.
