Jerry bought a coat on sale for 30% off. The sale price for the coat was $63, what is the regular price for the coat?
Answer:
The original regular price for the coat is $90
Step-by-step explanation:
The given information in the question are;
The percentage that was off (removed) from the sale price = 30%
The sale price at which Jerry bought the coat = $63
Whereby the regular price = P, we have;
P - 30% of P = $63
P - 0.3×P = $63
P×(1 - 0.3) = $63
0.7·P = $63
P = $63/0.7 = $90
Therefore, the regular (original) price for the coat = $90
The coat regular price at which the coat is displayed is at $90.

distance, midpoint, and angle measurement a walk in the park
Answer:
Step-by-step explanation:
The distance between to things is how far apart those two things are.
The Distance Formula is
d = √[(x1 - x2)² + (y1 - y2)²]
Midpoint: This is the point that bisects a segment in the middle.
The Midpoint formula is:
M = [(x1 + x2)/2, (y1 + y2)/2]
Angle is a point where two straight lines meet.

and proportions remain the same cach year?
A. $2.000
B. $2.100
C. $2.450
D. $3.000
E. $3.600
Answer:
3000
Step-by-step explanation:
Tony will donates $3000 after 5 years.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Donated amount= $1000
Tony is able to donate 3/2 times the amount that Theresa donates.
let Theresa donates x dollar each year
So, x+ 3/2x = 1000
5x/2 = 1000
5x = 2000
x= 400
Thus, Tony donate = 3/2 x 400 = $600
Hence, After 5 years Tony will donate= 600 x 5= $3000

Given a circle with endpoints of a diameter at –10 – 1i and 6 + 11i, answer the questions below. 1. The center of the circle is at ---+ --- i.
The center of the circle is at -2 + 5i.
What are Complex Number?Complex Numbers. Complex numbers are those that are expressed as a+ib, where a and b are actual numbers and I is a fictitious number called a "iota."
Complex numbers are numbers that consist of two parts — a real number and an imaginary number.
Given:
Diameter = –10 – 1 i = (- 10, - 1)
6 + 11 i = (6, 11)
Given that we are aware that these are the diameter's endpoints, it follows that the circle's center is the place that lies midway between the endpoints.
Then,
x = (-10 + 6) / 2
= - 4 / 2
= -2
y = (- 1 + 11) / 2
= 10 / 2
= 5
Hence, the center is located at (- 2, 5).

A store employee creates a display of sleds priced at $40 apiece. The store paid $32 for each sled. What is the mark-up percentage
Answer:
Mark-up percentage is 25%.
Step-by-step explanation:
From the question, the store bought each sled at $32 which is the cost price. The sled was display for sale at $40 apiece.
Mark-up percentage = [tex]\frac{selling price - cost price}{cost price}[/tex] x 100%
But,
selling price - cost price = $40 - $32
= $8
So that,
Mark-up percentage = [tex]\frac{8}{32}[/tex] x 100%
= 0.25 x 100%
= 25%
Therefore, the mark-up percentage is 25%.
Answer:

−8y−13=14y+11 what is the answer?
Answer:
y = -12/11
Step-by-step explanation:
-8y - 13 = 14y + 11
-8y - 14y = 11 + 13
-22y = 24
y = 24/-22
y = -12/11
Check:
-8*-12/11 - 13 = 14*-12/11 + 11
96/11 - 13 = -168/11 + 11
96/11 - 143/11 = -168/11 + 121/11 = -47/11
A rectangle has an area of 4x2 +19x + 12 and a length of (x + 4). What is the width?
The width of the rectangle with an area x² = 19x + 12 is (4x + 3).
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
We know the area of a rectangle is (length×widh).
Given, A rectangle has an area of 4x² + 19x + 12 and a length of (x + 4).
∴ width of the rectangle is = (4x² + 19x + 12)/(x + 4).
Or, we know that the product of two linear equations is a quadratic so,
4x² + 19x + 12.
4x² + 16x + 3x + 12.
4x(x + 4) + 3(x + 4).
(x + 4)(4x + 3).
So, the width of the rectangle is (4x + 3).

what is the absolute value of 2.3
The absolute value of any positive number is that number itself.
If you take the absolute value of a negative number, then just erase the negative sign and you have your answer.
The absolute value is never negative. It represents distance from that value to 0 on the number line.
So saying |2.3| = 2.3 means the number 2.3 is exactly 2.3 units away from 0 on the number line.
Another example would be |-7| = 7 showing that from 0 to -7 is 7 spaces.
The required absolute number of 2.3 is also 2.3.
GIven that,
An absolute number of the value 2.3 is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
The absolute number is defined as the outcome of the modulus function is called the absolute number or all natural numbers are examples of absolute numbers.
Here,
For the absolute value,
f(x) = |x|
f(2.3) = |2.3|
(since |x| = x or | -x | = x )
f( 2.3 ) = 2.3
Thus, the required absolute number of the value 2.3 is 2.3 itself.

Use the law of conservation of momentum to determine the answer to the
flowing question: In this group, there are two hockey pucks, both with a mass of
0.25 kg. One is traveling at 2 m/s. The other is at rest. What is the momentum of
this group of objects?
Given :
Two hockey of same mass.
One is travelling at a speed of 2 m/s.
Other is in rest or 0 m/s.
To Find :
The momentum of this group of objects.
Solution :
Since , no external force is applied , so momentum will remains same :
Momentum of group of objects ,
[tex]M = mv_1^2+mv_2^2\\\\M = 0.25\times 2^2+0.25\times 0\\\\M=1 \ kg \ m/s[/tex]
Therefore , momentum of the system is 1 kg m/s.
Hence , this is the required solution.
