Step-by-step explanation:
1st expression=
[tex] = {m}^{2} - {n}^{2} \: \: \: \: \: \: \: \: \: \: [/tex]
=(m-n) (m+n)
2nd expression=

What was the original price of an MP3 player that is advertised as on sale for 25%
off and the sale price is $60?
can i get an explanation, please :)
Answer:
$80
Step-by-step explanation:
the original price (in percent) = 100%
the discount (25% off) = - 25%
_________________
the sale price (in percent) = 75% =>
equal to $60
so, the original price =
100/75 × $60 = $80
Now
Cost price be x.[tex]\\ \rm\longmapsto 100-25=75\%[/tex]
75% of x=60[tex]\\ \rm\longmapsto \dfrac{75}{100}x=60[/tex]
[tex]\\ \rm\longmapsto x=60\times \dfrac{100}{75}[/tex]
[tex]\\ \rm\longmapsto x=80[/tex]
The angless of a quadrilateral are in the ratio 3:5:9:13. Find all the angles of the quadrilateral
Answer: 156°
Step-by-step explanation:
As you know angle sum of a quadrilateral = 360°
So, 3x + 5x + 9x + 13x = 360°
Or, 30x = 360°
Or, x = 12°
Hence: 3x = 36°, 5x = 60°, 9x = 108° and 13x = 156°
to rent a popcorn machine, it costs 35$ plus $6.95 for each hour. write and evaluate an expression to find the total cost of renting the popcorn machine for 5 hours. then make a table showing the cost for 5, 6, 7, and 8 hours
Answer:
y=6,95x+35
Step-by-step explanation:
y=6,95x+35
y=6,95*5+35=69,75 for 5 hours
for 6 hours y=76,7
for 7 hours y=83.65
for 8 hours y=90,6

IF ONE THIRD OF THE SCHOOL STUDENTS LIKE MATHEMATICS AND 400 STUDENTS DO NOT LIKE MATHEMATICS , THEN HOW MANY STUDENTS DOES THE SCHOOL HAVE ?
A. 600 B. 800
C. 200 D. 1000
Answer:
There are 600 students in this school.
Step-by-step explanation:
Let p represent the total population of the school.
Then (1/3)p represents the number of students who like math. Subtracting this (1/3)p from p gives an expression representing those who do not like math:
p - (1/3)p = (2/3)p
400 students do not like math, so (2/3)p = 400.
Solve this for p by multiplying both sides by (3/2):
(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.
There are 600 students in this school.

Find the image of (-1, 3) obtained by translating
2 units down, followed by a rotation of 180°
counterclockwise about the origin.
HELP QUICK
Answer:
(1, - 1 )
Step-by-step explanation:
A translation of 2 down means subtract 2 from the y- coordinate
(- 1, 3 ) → (- 1, 3 - 2 ) → (- 1, 1 )
Under a counterclockwise rotation about the origin of 180°
a point (x, y ) → (- x, - y ) , then
(- 1, 1 ) → (1, - 1 )
Overall
(- 1, 3 ) → (- 1, 1 ) → (1, - 1 )
The image of (-1, 3) was obtained by translating 2 units down, followed by a rotation of 180° counterclockwise about the origin is (1,-1).
What is coordinate?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The given point with coordinates of (-1,3), when translated downwards will have the coordinated equal,
(-1,3) ⇒ (-1, 3-2) ⇒ (-1, 1)
Now, since the translation is about 180° in the counter-clockwise direction, the coordinates of the new point will be equal to,
(-1,1) ⇒ (1, -1)
Hence, the image of (-1, 3) obtained by translating 2 units down, followed by a rotation of 180° counterclockwise about the origin is (1,-1).

Hint:
[tex](a^{m})^{n}=a^{m*n}[/tex]
Answer:
[tex]1/x[/tex]
Step-by-step explanation:
To simplify, work from the inside out.
We start with
[tex]\sqrt[4]{x^{3/4}}[/tex]
on the inside. And we can change the fourth root into a fractional exponent -- 1/4:
[tex](x^{\frac{3}{4})^{1/4}[/tex]
A power of a power means multiply the exponents, giving
[tex]x^{\frac{3}{4} * \frac{1}{4}} = x^{3/16}[/tex]
So now we have
[tex][(x^{3/16})^{-4/3}]^4[/tex]
From here, apply the "power of a power rule" again, working from the inside out.

Now, when we are talking about congruency, we are simply referring to the concept of equality.
Thus, when we say that two angles are congruent, it simply means they are equal.
Now, when we introduce a mid point to a line segment, what this does is to divide the line into two equal parts.
Equal segments are congruent and as such we can say that congruent segments are formed.

HELP!!! Will mark brainliest!!
Step-by-step explanation:
BDC and ACD are complementary with each other. that means together they cover the full 180 degrees of the half circle that can be drawn on one side of a flat line.
180 = 11x + 25 + 4x + 5 = 15x + 30
150 = 15x
x = 10
BDC = 11x + 25 = 11×10 + 25 = 110 + 25 = 135 degrees
ACD = 4x + 5 = 4×10 + 5 = 40 + 5 = 45 degrees

Find the distance between the pair of points. (5,25) and (−19,−12) The distance is nothing. (Round to the nearest thousandth as needed
Answer:
44.1
Step-by-step explanation:
- To find the distance, we have to use the distance formula:
d = √(x2 - x1)² + (y2 - y1)²
d = √(-19 - 5)² + (-12 - 25)²
d = √(-24)² + (-37)²
d = √(576) + (1369)
d = √1945
d = 44.1

The midpoint of AB is M(3,-2). If the coordinates of A are (1, -3),
what are the coordinates of B?
Answer:
23 just took the test
Step-by-step explanation:
Answer:
B(5,-1)
Step-by-step explanation:
The formula for finding the midpoint of any line is: [ (x1+x2) / 2 ] , [ (y1+y2) / 2 ] .So, x1=1 and x2=x. And y1=-3 and y2=y.
So,
(1+x)/2=3, then manipulating it gives x=5.
And,
(-3+y)/2=-2, then manipulating the equation gives y=-1.
Hence B(5,-1)
