Answer/Step-by-step Explanation:
Circumference of a circular object = πd
Where,
π = 3.14,
d = diameter
Circumference of hula pop with diameter of 35 in:
Circumference = πd = 3.14*35 = 109.9 in
Diameter of circular pond with a circumference of 556 ft:
556 = 3.14*d
Divide both sides by 3.14
556/3.14 = d
177.07 = d
d ≈ 117 in
Circumference of magnifying glass with a diameter of 5.2 in:
Circumference = πd = 3.14*5.2 = 16.328 ≈ 16.4 cm
Diameter of car tire with a circumference of 71.6 in:
71.6 = 3.14*d
Divide both sides by 3.14
71.6/3.14 = d
22.80 = d
d ≈ 22.8 in

im not really sure what 10 is
Answer:
- Benito's error was using the equal sign (=) instead of the congruency symbol (≅).
Explanation:
Benito's error was using the equal sign (=) instead of the congruency symbol (≅).
The congruency symbol (≅) means that the elements (segments, angles or figures in general) have the same measure, i.e. they have equal lengths for the segments or equal measure for the angles.
For instance, it is an error saying that the segment AB is equal to the segment BC because, as you clearly see in the picture, they are not same; they have the same length but they are joining different points, that makes them different in essence, although they have the same length. They would be equal only if they are the same figure.
In mathematics, you must not say that two different segments or two different angles are equal but they are congruent, which means that their lengths are equal. The use of equal is reserved for numbers and variables, not for figures like segment, points, angles, polygons.
Answer:
An angle bisector is a line passing through the vertex of the angle that cuts the angle into two equal smaller angles.
Given: MN is angle bisector,
then
....... [1]
Congruent angles are two or more angles that have the same measure.
then;
by definition of congruent angles
[1]⇒ 
......[2]
By the Angle addition postulates states that if M is in the interior of ∠JMK then,
......[3]
Now, by substitution property ; substitute the equation [2] in [3] we get;
......[4]
Like terms terms whose variables are the same
Combine like terms in equation [4] we get
......[5]
Division property of equality states that you divide the same number to both sides of an equation.
Divide by 2 to both sides in equation [5] , we get
Answer:
Melody have now $27.75
Step-by-step explanation:
We will proceed to solve the problem in parts so that it can be better understand
so
1) Originally Melody had $45
2) She spent $32.75 on a blouse
so
In this moment Melody has --------> $45-$32.75=$12.25
3) Her mother gave her $15.50
so
In this moment Melody has --------> $12.25+$15.50=$27.75
therefore
Melody have now $27.75
