A(0,-3), B(3,-2), C(1, -1) (B) is the coordinates of ΔA'' B'' C'' after a reflection in the x -axis and a rotation of 180.
What does the term "coordinates" mean?
Coordinates are numerical lengths or angles that uniquely identify locations on two-dimensional (2D) surfaces or in three-dimensional (3D) space ( 3D ). Mathematicses, scientists, and engineers frequently employ a variety of coordinate systems.A 180 degree clockwise rotation will change the coordinates as follows (x,y) --> (-x,-y)
A(-3, 0), B(-2, 3), C(-1, 0) -->
A(3, 0), B(2, -3), C(1, -1)
Reflection across the line y=-x will change the coordinates as follows (x,y) --> (-y,-x)
A(3, 0), B(2, -3), C(1, -1) -->

A standard 1 kilogram weight is a cylinder 54.5 mm in height and 53.0 mm in diameter. what is the density of the material?
The density of the material is 0.4 kg/cubic cm.
Given that:-
Height of the cylinder = 54.5 mm
Diameter of the cylinder = 53.0 mm
Weight of the cylinder = 1 kg
We have to find the density of the cylinder.
We know that,
Density = mass/volume
Here, mass = 1 kg
We know that,
Volume of a cylinder = [tex]\frac{1}{3} \pi r^2 h[/tex]
Where,
r is the radius of the cylinder, and
h is the height of the cylinder
Here, h = 54.5 mm, and
r = 53/2 = 26.5 mm
Hence,
Volume of cylinder = (1/3)*(22/7)*(26.5)(26.5)*54.5 ≈ 2566.088 ≈ 2566 cubic mm. = 2566/(10*10*10) cubic cm = 2.566 cubic cm
Density of cylinder = 1kg/2.566 cubic cm ≈ 0.3897 ≈ 0.4 kg/cubic cm.

Step-by-step explanation:
Let y represent distance in miles and x represent gallons of gas.
a. First of all, we will find mileage of Ann's car by dividing total distance traveled by total fuel consumed.
Mileage of Ann's Car: [tex]=\frac{228 miles}{6 gallons}[/tex]Mileage of Ann's Car:[tex]=\frac{38 miles}{gallon}[/tex]Since Ann's can travels 38 miles per gallon, so distance covered by using x gallons on gas would be [tex]38x[/tex] .

Step-by-step explanation:
You will have to use the pythogoras. triple to solve the equation
Answer:
314 mStep-by-step explanation:
the diagonal is the hypotenuse of the two triangles that form the rectangle (see figure) we solve with Pythagoras
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides
a² = b²+ c²
a² = 250² + 190²
a² = 62500 + 36100
a² = 98600
a = √98600

Canon borrows $3,000 at a yearly simple interest rates of 1.6% for 2 years how much does he owe in interest and how much does he need to pay back in all
Interest is Rs.96 and Total amount payback is Rs.3096.
Principal (P) = Rs.3000
Rate of interest (R) = 1.6%
Number of years (N) = 2 yrs
Simple interest = PNR/100
= (3000*1.6*2)/100
=(9600/100
=96Rs
Total Amount (A) = P+I
=3000+96
=3096Rs
The principal, or initial balance of your account, is where interest is calculated. This could be the initial sum of a loan or an investment. The simplest way to compute interest is as a percentage of the principal .Only relatively short-term loans frequently include one-time basic interest charges. Interest is frequently paid on a daily, monthly, quarterly, or annual basis for loans with longer terms. In that scenario, interest would be consistently earned.
Hence, the interest for the above principle is 96Rs and the total amount to be payback is 3096Rs.

Find the least number of houses sold in January.
The total number of houses sold in January by Coventry Estates are 18.
How to do the twice of number? This suggests that the amount of A is twice as large as the quantity of anything else, which in this case is B. So, if you have a dozen B items, you have twice a certain number for A, which is 24.As per the given question;
Let the total sales of the houses in January be 'x'.
In February they sold twice as many houses as in January.
February = 2x.
In March they sold 10 more houses than in February.
March = February + 10
March = 2x + 10
In April they sold half as many houses as in March.
April = March/2
April = (2x + 10)/2 = x + 5
The total sold houses = 123.
Add all the sold houses;
x + 2x + 2x + 10 + x + 5 = 123
6x + 15 = 123
On simplification;

The shortest length of fabric, in inches, that Kirk could use to make the tablecloth without putting any separate pieces of fabric together is 30 inches
How to solve for the shortest length of fabric required to make the table clothGiven data
diameter of the table = 3 feet
hang down dimension = 5 inches
sew down dimension = 1 inch
width of rectangular fabric = 60 inches
The question seeks for area of the table cloth, for a circular table area of a circle = pi * r^2
required radius of cloth
= radius of the table + hang down dimension + sew down dimension
= 3 feet / 2 + 5 inches + 1 inch
= 1.5 * 12 inches + 5 inches + 1 inch
= 18 + 5 + 1
= 24 inches
Area of required cloth
= pi * 24^2
= 1809.557 square inches
Area of fabric = Area of required cloth
length * wide = 1809.557 square inches
length * 60 = 1809.557 square inches
length = 1809.557 / 60 square inches
length = 30.159 inches ≈ 30 inches

A regulation volleyball has a circumference of about 66 centimeters. The ratio of the surface area of that ball to the surface area of a children's ball is approximately 1.6: 1 . What is the circumference of the children's ball? Round to the nearest centimeter.
The circumference of the children's ball to the nearest centimeter is 52 centimeters.
If a regulation volleyball has a circumference of about 66 centimeters, solve for its radius using the formula for the circumference of a circle given by:
C = 2πr
66 centimeters = 2πr
r = 33/π centimeters
Then, solve for the surface area of this regulation volleyball using the formula given by:
A = 4πr^2
A = 4π(33/π centimeters)^2
A = 4356/π square centimeters
If the ratio of the surface area of that ball to the surface area of a children's ball is approximately 1.6 : 1, then
surface area of regulation volleyball : surface area of a children's ball = 1.6 : 1
surface area of a children's ball = 4356/π square centimeters/1.6
surface area of a children's ball = 2722.5/π square centimeters
If the children's ball has a surface area of 2722.5/π square centimeters, solve for its radius using the formula for the surface area given by:
A = 4πr^2
2722.5/π square centimeters = 4πr^2
r = 26.0887907/π centimeters
Solving for the circumference:
C = 2πr
