Answer:
Radius = 504units
Step-by-step explanation:
Angle = 10°
Length of arc = 28π units
L = ∅/360 × 2πr
28π = 10/360 × 2πr
28π = 1/36 × 2πr
2πr = 28π × 36
π cancelled off.......
2r = 28 × 36
r = (28 × 36)/2
r = 28 × 18
r = 504units
The radius of circle is 504 unit.
What is sector?A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends. A slice of pizza or a pie can be used as an analogy for the form of a circle's sector.
We have,
arc length = 28π unit
Central angle = 10°
so, length of Arc
28 π= 2πr (10/360)
28 = 2r (1/36)
14 = r/36
r= 504 units

The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Answer:
6 sides
Step-by-step explanation:
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Let us represent:
Sum of Exterior angle as x
Sum of Interior angle as y
Note that:
The sum of the exterior angles of a polygon = 180 - The sum of the interior angles
Hence,
The sum of the exterior angles of a polygon + The sum of the interior angles = 180
x + y = 180
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles.
2x = y
Substituting
x + 2x = 180°
3x = 180°
x = 180/3
x = 60°
Solving for y
2x = y
2 × 60° = y
120° = y
Hence,
Sum of Exterior angle as x = 60°
Sum of Interior angle as y = 120°
The number of sides of a polygon is
360°÷ Sum of Exterior angles
= 360° ÷ 60
= 6 sides
The diameter of a circle is 2 kilometers. What is the radius?
Answer:
The radius of the circle is 1 kilometer.
Step-by-step explanation:
The radius of the circle is the length from the very center of the circle to any other point in the circle. To find the radius, you only have to divide the diameter in half, so 2 ÷ 2 = 1. Hope this helped!! :]

Taylor has $20 to spend on school supplies. A pack of
colored pencils is $2.75. Taylor writes the inequality
2.75p < 20, where p is the number of packs of colored
pencils, taldetermine how many packs she can buy.
How many packs can she buy?
Answer:
7 packs
Step-by-step explanation:
2.75p < 20
Divide both sides by 2.75
2.75p/2.75 < 20/2.76
Simplify
p = 7.27 (27 repeating)
Round
p = 7

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
Now, We can simply as;
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
⇒ 2 ln 2x - ln 10x = ln 30
⇒ ln (2x)² - ln 10x = ln 30
⇒ ln (2x)² / 10x = ln 30
⇒ 4x² / 10x = 30
⇒ 4x = 300
⇒ x = 75
Thus, The true solution to the equation is,
⇒ x = 75

In the diagram, △ABC∼△CDE. Write an equation for line k
Answer:
Step-by-step explanation:
Line AB is parallel to line CD (k) so they have the same slope.
slope=m=(y2-y1)/(x2-x1)
m=(6-0)/(4-0)
m=6/4=1.5
y=mx+b, we know m=1.5 so
y=1.5x+b, and we know it passes through point (4,0) so we can solve for b
0=1.5(4)+b
0=6+b
b=-6 so line k is
y=1.5x-6
