How do you find the length of arc and area of sector

Answers

Answer 1

Answer: To do this I must first determine what fraction of the circle is represented by the central angle 30°. Since there are 360° in a full circle, I can find the fraction of a circle by simplifying . The sector represents of the circle. To find the arc length, I now need to find the circumference of the entire circle.

Does anyone know how to to explain slope in a easy way

Answers

When you are given two points of a line, you can find the slope of the line.

Let's say that the two points we are given is $\sf(x_1,y_1) ~and ~(x_2,y_2)$ , then the slope is:

$\bf{Slope = (y_2-y_1)/(x_2-x_1)$

Another thing to keep in mind:

When you have 0 in the numerator, and a number in the denominator, that means that the slope is 0.
When you have 0 in the denominator, and a number in the numerator, that means that there is no slope, or that the slope is undefined.

1.2x-4y=28 solve for y

Answers

2x -4y= 28
⇒ -4y= 28 -2x
⇒ y= (28 -2x)/ (-4)
⇒ y= 28/(-4) -(2x)/ (-4)
⇒ y= -7 + 1/2x

The final answer is y= -7 + 1/2x~

Final answer:

To solve for y in the equation 1.2x - 4y = 28, subtract 1.2x from both sides, divide both sides by -4, and simplify to get the solution y = -7 + 0.3x.

Explanation:

To solve the equation 1.2x - 4y = 28 for y, we need to isolate the y variable on one side of the equation.

Step 1: Subtract 1.2x from both sides.

Step 2: Divide both sides by -4.

Step 3: Simplify.

Step 4: The solution for y is -7 + 0.3x.

Tracy goes on a 3 day and night school band trip. There is no cost for travel and each band member only pays half the cost of the hotel room. However, each person is responsible for the cost of their own meals. His portion of the hotel bill is $49 per night and Tracy leaves a 10% tip for the maid service. Before tax, Tracy spends $32 per day on eating out plus 15% of this amount in tips. If Tracy spends a total of $280.74 on the band trip, what percent tax was Tracy charged on his food?

Answers

The total amount she spent is equal to the sum of the amount for food and hotel accommodation. Letting x be the percent tax that Tracy was charged for his food, the equation that best represent the given is,
280.74 / 3 = 49 + (0.10)(49) + 32 + (0.15)(32) + (x)(32)
The value of x from the equation is 0.09. Thus, Tracy is charged 9% tax on his food.
