What are the coordinates of B(-4, -5) under a 180 degree rotation about the origin?
Answer:
(4, 5 )
Step-by-step explanation:
Under a rotation about the origin of 180°
a point (x, y ) → (- x, - y ), thus
B(- 4, - 5 ) → (4, 5 )

12 POINTS TO THE BRAINLIEST ANSWER!!!! PLEASE HELP!! Tess and Dan have $24.00 each to spend at a book fair, where all students receive a 15% discount. They both want to purchase a copy of the same book, which normally sells for $24.50 plus 10% sales tax. To check if she has enough to purchase the book, Tess takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Dan takes 85% of the normal purchase price and then computes 110% of the reduced price. Is Tess correct? Is Dan correct? Do they have enough money to purchase the book? Explain your answer using complete sentences. PLEASE ANSWER ALL QUESTIONS
Answer:
yes Dan and Tess have enough money because the price is 22.9075 after discount
Step-by-step explanation:
the original price of the book=24.50
the price of the book with taxes : 24.5+(24.5*10 %)=26.95 Dollars
the price for the students is : 24.50-(24.5*15%)=20.825
the price to students +tax= 20.825+(20.825*10%)= 22.9075
See what Tess did:she took 15 % from original price :24.50-(24.5*15%)=20.825
she took 10 % of discounted price :20.825.50*10%= 1.04125
adds it back to find the purchase amount:1.04125+20.825=21.86625
what Dan did:Dan takes 85% of the normal purchase price: 24.50*85%= 20.825
then compute 110% to the discounted price: 20.825*110%=22.9075
Dan is right, he will pay 22.9075 which is actually the price that the student pay for the book after the discount. what Tess is that she calculated the tax before discount, she has to calculate the tax after discount.
7. Find the value of:
a) The number when 40% of the number is 10
Step 1) Set up a proportion
Proportion: percent / 100 = x / number
In context of the problem, the proportion is: 40 / 100 = 10 / number
Step 2) Cross-multiply and solve
100 x 10 = 40 x N
1000 = 40N
N = 25
Answer: The number is 25
Answer:
25Step-by-step explanation:
Let the unknown number be x
[tex]40 \% \times x = 10 \\ \frac{40x}{100} = \frac{10}{1} [/tex]
Cross Multiply
[tex]40x = 100 \times 10 \\ 40x = 1000[/tex]
Divide both sides of the equation by 40
[tex] \frac{40x}{40} = \frac{1000}{40} [/tex]
Simplify
[tex]x = 25[/tex]

Solve for b.
y = mx + b
Answer:
b = y - mx
Step-by-step explanation:
So we are trying to solve for b in the equation y = mx + b. To do this, we will have to somehow get the b by itself on one side and all of the non-b parts of the equation on the other side.
y = mx + b
Subtract mx from both sides.
y - mx = b
b = y - mx
So we have not solved for b. We have found that b = y - mx.

what describes the first factor in scientific notation
Answer:
mantissa
Step-by-step explanation:
The word "mantissa" is used to describe the portion of the number that represents the significant digits in scientific notation.
__
The term also refers to the fractional portion of a logarithm. Of course, that fractional portion also represents the significant digits of the number. The integer portion of the logarithm is the power of 10 that multiplies the significant digits.

The length of the rectangle below is (2x-3) and the width is (x+7). Find the area of the rectangle in terms of x.
Answer:
area = 2x² - 17x - 21
Step-by-step explanation:
Area of the rectangle is:
area = (width*length)
area = (x+7)*(2x-3)
= x*2x + x*-3 + 7*2x + 7*-3
= 2x² - 3x - 14x - 21
= 2x² - 17x - 21
The area of the rectangle in terms of x should be [tex]2x^2 + 11x - 21[/tex]
Given that,
Length is 2x - 3.Width is x + 7.We need to determine the area of the rectangle
As we know that
The area of the rectangle be
[tex]= length \times breadth\\\\= (2x - 3) (x + 7)\\\\= 2x^2 +14x - 3x - 21\\\\= 2x^2 + 11x - 21[/tex]
Therefore we can conclude that The area of the rectangle in terms of x should be [tex]2x^2 + 11x - 21[/tex]

Rewrite the equation below using ONLY the symmetric property of equality:2x + 5 = 3x -7
Answer:
12 = x
Step-by-step explanation:
Symmetry here would involve subtracting the same quantity from both sides of the equation.
Starting with 2x + 5 = 3x -7,
subtract 2x from both sides. This yields
5 = x - 7
Adding 7 to both sides yields
12 = x

The distance an object travels is determined by how fast it goes and for how long it moves. If an object’s speed remains constant, the formula is d=r*t , where d is the distance, r is the speed, and t is the time. If you drive at 50 miles per hour for 5 hours, how far will you have traveled? a. 200 miles b. 10 miles c. 250 miles d. 300 miles Please select the best answer from the choices provided A B C D
Answer:
d = r * t
r = 50 mph
this will be very easy.
d = r * t
r = 50 mph
t = 5 hours
d = 250 miles
In five hours at a constant speed of 50 miles per hour, you would have traveled 250 miles.t = 5 hours
d = 250 miles
In five hours at a constant speed of 50 miles per hour, you would have traveled 250 miles.

Dimensions of a Box A large plywood box has a volume of . Its length is ft greater than its height, and its width is ft less than its height. What are the dimensions of the box
Answer:
Few things are missing, they are volume of the box is 180 feet cube. Length is 9 feet greater than its height, and weight is 4 feet less than its height.
Step-by-step explanation:
Given, the volume of the box, V = 180 feet cube
Let the height of the box, h = x feet
Therefore, length is, l = ( 9+x ) feet
And width is, b = ( x-4) feet
so volume of the box is
V = l x b x h
[tex]$ 180= (x+9) \times (x-4) \times (x)$[/tex]
[tex]$ x^3 +5x^2-36x -180 =0$[/tex]
Factorizing we get
(x+5)(x-6)(x+6)=0
Therefore,
x = -5, -6, 6
Now since the height of the box cannot be negative, so taking the positive value of x, we get
Height of the box, h = x = 6 feet
Length , l = ( 9+x ) = 9+6 = 15 feet
Width , b = ( x-4) = 6-4 = 2 feet

Answer:
The correct options are;
B. AC and AD have the same length
D. Triangle BCE is isosceles
Step-by-step explanation:
From the diagram we have;
B. Segment AC and segment CD are the radii of the same circle with center C and radius AC, therefore, given that the radius of a circle is constant round a circle, we have;
The length of AC = The length of AD
D. In triangle BCE, we have the length of segment CB is equal to the length of segment CE which are both radii of the circle with center C and radius CE, therefore, the triangle BCE has two sides equal which gives triangle BCE is an isosceles, from the definition of isosceles.
What are the factors for 15x - 4 - 8?
find the dimension of the missing side of a triangle given the following measurements: A=75 sq. ft, b=15 ft, h=?
Answer:
h = 10 ft
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh
Here A = 75 and b = 15, thus
[tex]\frac{1}{2}[/tex] × 15h = 75 ( multiply both sides by 2 to clear the fraction )
15h = 150 ( divide both sides by 15 )
h = 10
