Answer:
1. 25
2. 24
equations below
Step-by-step explanation:
Order of operations is: PEMDAS = parentheses, exponents, multiplication, division, addition, subtraction
1. 5 x (20/4)
normally we multiply before we divide, but in this case, the division is in parentheses, so we start there
= 5 x 5
then multiply
= 25
------------------------
2. The lovely land of exponents
6^2 (the only way I can type 6 squared, or 6 to the power of 2, where the 2 is up as a superscript)
6^2 - 2 x 6
PEMDAS has us do the exponents before multiplication or subtraction:
6^2 = 6 x 6 = 36
= 36 - 2 x 6
then multiply:
= 36 - 12
then subtract:
= 24

A stop sign is in the shape of an octagon. Find the perimeter if each side is 2a + 1 units
Answers
Given,
Side of the octagon = ( 2a + 1 ) units» Perimeter means total length of its boundary.
→ Octagon has 8 sides.
So,
→ Perimeter of Octagon = Length of 8 sides
→ Perimeter of Octagon = 8 ( 2a + 1 ) units
→ Perimeter of Octagon = 16a + 8 units
Therefore,
Perimeter of the octagon is [tex] \bf 16a + 8 [/tex] units.Step-by-step explanation:
Side of the octagon
An octagon has 8 sides. Each side is 2a + 1 units.

Which statement about gravity is true?
A. Gravity pulls all objects together, big or small
B. Gravity decreases as mass decreases
C. Gravity decreases as distance increases
D. Gravity pulls only very large objects together
Please help, If I don't get at least a B my parents will kill me.
Answers
Answer:
D is false
A is true
B is true
C is true
Step-by-step explanation:
Answer:
I this a multiple choice answer? I found that A B and C are true.
I know this because the article Newtons laws of Universal Gravitation states that "Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases." This makes C the best answer

Answer:
angle c = 107°
angle b = 107°
angle a = 73°
Step-by-step explanation:
Given:
Two line XY and WZ intersect each other and make four angle [a, b, c, d]
Given that Angle d = 73°
Find:
angle a
angle b
angle c
Computation:
We know that angle c and angle d situated on same line XY
So,
angle c + angle d = 180°
angle c + 73° = 180°
angle c = 107°
We know that angle b and angle d situated on same line WZ
So,
angle b + angle d = 180°
angle b + 73° = 180°
angle b = 107°
angle a and angle d are vertical opposite angle
So,
angle a = angle d
angle a = 73°

Answer:
height = 6.92820323028km (you can round if you want to)
Step-by-step explanation:
8km - 4km = 4km (this is for one of the side lengths of the traingle)
a² + b² = c²
4² + b² = 8² (b will be used to represent the height)
16 + b² = 64
b² = 48
b = 6.92820323028km

Step-by-step explanation:
Given data
We are told that 1 ounce cost $4.12
Hence 6.25 ounces will cost x
cross multiply
x= 6.25*4.12
x=$25.75
This means that the cost of the 6.25 ounces is $25.75
If the teacher pays with a $50 bill, then her change is
=50-25.75
=$24.25

Quadrilateral PQRS
Reflected over x-axis
Required
Congruent side to QR
This question has a missing attachment, but can still be solved without the attachment.
When a shape is reflected, the sides and the angles of the shape remain unchanged.
This means that when PQRS is reflected to give P'Q'R'S, the following sides will be congruent.
[tex]PQ = P'Q'[/tex]
[tex]QR = Q'R'[/tex]
[tex]RS = R'S'[/tex]
[tex]SP = S'P'[/tex]
Hence, QR will be congruent to Q'R'
