What is the arc length of arc CD in the circle below? Radius is 8ft and central angle is 35 degrees

1 answer:

3 0

This depends on the question itself. But I will assume and provide an answer.

If arc CD is made from the central angle intercepting the perimeter of the circle( so if the central angle is CBD, then the arc is from the two endpoints of the angle) that would mean that the arc is 35 degrees. If the two endpoints of the arc are NOT the two points from the angle that lie on the circle, then I cannot provide an answer without a picture.

To sum it up, if the arc begins and ends on the two endpoints of the angle, then it is 35 degrees. Unless it goes the long way around, then it would be 325, but that's unlikely to be the case.

Which system of linear inequalities Is represented by this graphed solution?

SashulF [63]

Answer:

y ≥ 3x - 1

y < $-\frac{1}{2}x+2$

Step-by-step explanation:

Let the equation of the solid line passing through (x', y') given in graph is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of the solid line =

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

m = 3

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = 3x - 1

Since, shaded (blue) area is above the line, inequality that will represent the solution area will be,

y ≥ 3x - 1

For the dotted line,

Slope of the line (m) = $\frac{\text{Rise}}{\text{Run}}$

= $\frac{-2}{4}$

= $-\frac{1}{2}$

y-intercept (b) = 2

Equation of the dotted line → y = $-\frac{1}{2}x+2$

Since, shaded (grey color) area is below the dotted line,

Inequality representing the solution area will be,

y < $-\frac{1}{2}x+2$

How to find area of composite figures

Romashka [77]

Answer:

↓↓↓↓↓

Step-by-step explanation:

A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles. To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.

Helena needs 3.5 cups of flour per loaf of bread and 2.5 cups of flour per batch of muffins. She also needs 0.75 cup of sugar pe

lyudmila [28]

Given the choices, the best fitting answer would be the first one. "2 loaves of bread and 4 batches of muffins". I figured this out by multiplying the amount of flour and sugar required for each loaf of bread and batch of muffins

Which answer explains the correct way to move the decimal to find the quotient of 23.8 × 100?

natima [27]

The correct way to move the decimal to find the quotient is b. two places to the right.

This is because 100 has two zeroes in it, so you know that you have to move the decimal either two places to the right or two places to the left.

100 is a positive number, and when multiplied by a positive number with a decimal, it makes an even larger number. So, you would move 23.8 decimal place two places to the right.
