the length of an arc of a circle is 269πcentimeters and the measure of the corresponding central angle is 65∘. what is the length of the circle's radius?
Answers
The length of the circle's radius = 744.92 cm
Given the length of arc of a circle, arc length = 269π cm
Central angle of a circle is the angle made between the radius through the arc length at the center of the circle.
The corresponding central angle = 65°
To find the corresponding central angle in radians = 65° x π/180 = 13π/36 radians
We have, arc length of a circle = radius x central angle
Therefore, radius of the circle = arc length / central angle
= 269π /(13π/36)
= 744.92 cm

What is the purpose of the list of grievances?
to list the reasons the colonists are abolishing their government
to explain the purpose of natural rights to the king
to declare that the United States of America is a free and independent state
to show that the colonists understand the importance of their actions
Answers
The purpose of the list of grievances is to declare that the United States of America is a free and independent state.
The colonists' complaints against King George's treatment of them were listed in the list of grievances. It was essentially a list of justifications for their declaration of independence.
A list of complaints that Thomas Jefferson thought George III, the king of Great Britain, had made against the colonists is included in the Declaration of Independence. The primary justifications for the Colonists' involvement in the American Revolution were described in these grievances. Taxation without representation, or as Thomas Jefferson more elegantly puts it, "for imposing Taxes on us without our Consent," is arguably the most significant of them.

Use the greater than and less than symbols to compare values and expressions. > is the symbol for more than. 6.5 is commonly thought to mean 6.5 "6.5 is the same as 6.5. " "= "is the sign of equality. Two more comparison expressions are "greater than" and "equal to" (less than or equal to).
Two values are equal when the "equals" sign is used to indicate this. (=)
When two values are obviously not equal, the "not equal to" signal is used. (≠)
To show that one value is smaller than another, we use the "less than" sign. (<)
To show that one value is greater than another, we use the "greater than" symbol. (>)

Answers
The slope of the line in simplest form is: 1.
How to Find the Slope of a Line?The slope (m) of a line is calculated as:
Slope (m) = rise/run = change in y / change in x.
The horizontal distance across the line is the run, while the vertical distance is the rise.
The blue line shows the rise of the line = 2 units

in infant's Tylenol, 5 ml contains 160 mg of Acetaminophen. If you child's pediatrician says that your child can take 48 mg of Acetaminophen, how many milliliters (ml) should you give the child?
Answers
The amount of milliliters (ml) you should give the child is 1.5 ml
How to determine how many milliliters (ml) you should give the child?The given parameters are:
infant's Tylenol, 5 ml = 160 mg
This can be represented as
5 ml = 160 mg
Let the number of ml to give a child that requires 48 mg be x
So, we have:
5 ml = 160 mg
x = 48 mg
Cross multiply
x * 160 = 48 * 5 ml
Divide both sides by 160
x = 1.5 ml
Hence, the amount of milliliters (ml) you should give the child is 1.5 ml

Answers
Answer: XYW = 32, WYZ = 85
Step-by-step explanation:
We are looking for what x is, which we can find with the formula:
117 = (6x+44) + (-10x+65)
117 = -4x + 109
8 = -4x
x = -2
We can verify this is correct by plugging it in and seeing if they add up to 117.
6x + 44 (XYW)
= 6(-2) + 44
= -12 + 44
= 32
-10x + 65 (WYZ)
= -10(-2) + 65
= 20 + 65
= 85
32 + 85 = 117

In the figure below, m44 = 79°. Find m1, m2, and m 3
Answers
The angle of m1, angle of m2 and angle of m3 is 101°, 79° and 101° respectively.
It is given that the angle of m4 is 79°.
To find angles m1, m2 and m3 :
As we know that angle m4 is equal to angle m2 (because they are vertically off opposite angle).
So, angle m2 = 79º
In the same manner the angle of m1will be equal to angle m3.
Now, we can see that in the figure the angles m2 and m1 is lying on one plane, and a plane line makes a angle of 180º
So,
m2+m1 = 180º
79º+m1 = 180º
m1 = 180º-79º
Angle m1 = 101º
And, as we can see that the angles m1 and m3 are vertically of opposite angle.
So, m1= m3= 101º
Hence, angle m1=101º,
angle m2= 79º,
And, angle m3=101º.

Using the cross-multiplication formula we conclude that 768 cents will be given for 96 can recycled.
What is cross-multiplication?Cross multiplying is the process of multiplying the denominator of the second fraction on the other side of the equals to sign by the numerator of the first fraction on the same side.
In a similar manner, the numerator of the second fraction is multiplied by the denominator of the first fraction. Cross-multiplication is another name for the butterfly method. We employ the cross-multiply approach to identify one or more variables in a fraction. Cross multiplying is another method for comparing fractions.
We will do simple cross-multiplication here
given that for 12 cans we get 96 cents, that is
