Hence, divide both the numerator and denominator by 24 ;
Numerator = 48/24 = 2
Denominator = 72 / 24 = 3
= 2/3
I'm bad at math. a plan for a baseball diamond is drawn in a coordinate plane. the baseball diamond is in a shape of a square.with vertices at approximately (0,64),(64,0),(0,—64), and (—64,0). one unit in the coordinate plane represents 1 ft. what is the approximate area of the baseball diamond? what is the area of the trapezoid shown?
Answer:
Area of diamond=8192
Area of trapezoid =72 square unit
Step-by-step explanation:
Area of diamond:
find the distance between the points:
(0,64), (64,0), (0,-64),(-64,0)
d=√(x2-x1)²+(y2-y1)²
d=√64²+64²
d=64√2=90.51( rounded to the nearest hundredth)
since it is shape of square then all sides are equal
A=length*width
A=64√2*64√2
A=8192 square unit4- Area of trapezoid= ((base a +base b)/2) h
base a=3, base b=6 height=8 ( from graph count the tiles)
Area of trapezoid = ((3*6)/2 )* 8
Area=18/2*8
Area=9*8=72 square unit
The area of a diamond is 8192 square units and the area of a trapezoid is 72 square units.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
The area of the diamond will be calculated as below:-
find the distance between the points:
(0,64), (64,0), (0,-64),(-64,0)
d=√(x2-x1)²+(y2-y1)²
d=√64²+64²
d=64√2=90.51( rounded to the nearest hundredth)
Since it is the shape of a square then all sides are equal
A=length x width
A=64√2 x 64√2
A=8192 square unit
The area of the trapezoid will be calculated as below:-
Area of trapezoid= ((base a +base b)/2) h
base a=3, base b=6 height=8 ( from graph count the tiles)
Area of trapezoid = ((3*6)/2 )* 8
Area=( 18/2 ) x 8
Area=9 x 8=72 square unit
Therefore, the area of a diamond is 8192 square units and the area of a trapezoid is 72 square units.

Un grupo de personas se reúnen para ir de excursión, juntándose un total de 20 entre hombres, mujeres y niños. Contando hombres y mujeres juntos, su número resulta ser el triple del número de niños. Además, si hubiera acudido una mujer más, su número igualaría al de hombres. ¿Cuántos hombres, mujeres y niños han ido de excursión?
Answer:
El número de hombres = 8 hombres
El número de mujeres = 7 mujeres
El número de niños = 5 niños
Step-by-step explanation:
El número total de personas en la excursión = 20
La suma de los hombres y las mujeres = 3 veces el número de hijos
El número de mujeres = 1 menos el número de hombres
Sea el número de hijos = A
Sea el número de mujeres = B
Sea el número de hombres = C
Tenemos;
B + C = 3 × A .................... (1)
B = C - 1 .......................... (2)
A + B + C = 20 .............. (3)
Sustituyendo el valor de A + B en la ecuación (1) en la ecuación (3), tenemos;
A + B + C = 20
A + 3 × A = 20
4 × A = 20
A = 5
Sumando la ecuación (1) a la ecuación (2), obtenemos
B + C + B = 3 × A + C - 1
2 · B + C - C + 1 = 3 · A
2 · B + 1 = 3 · A = 3 × 5 = 15
2 · B + 1 = 15
B = (15 - 1) / 2 = 7
B = 7
De la ecuación (2),
B = C - 1
7 = C - 1
C = 7 + 1 = 8
El número de niños = 5
El número de mujeres = 7
El número de hombres = 8.

How do I do? What is the answer and why
Answer:
Step-by-step explanation:
∠ADE = 74 {Vertically opposite angles are equal}
∠AED + 127 = 180 {Straight line }
∠AED = 180 - 127
∠AED = 53
In ΔADE,
∠DAE + ∠AED + ∠ADE = 180 {angle sum property of triangle}
∠DAE + 53 + 74 = 180
∠DAE + 127 = 180
∠DAE = 180 -127
∠DAE = 53

The first floor of the Willis Tower is 21 feet high. Each additional floor is 12 feet high.
a
Write an equation for the nth floor of the tower.
b.
Find the height of the 65th floor.
Answer:
Step-by-step explanation:
If the first floor of the Willis Tower is 21 feet high. and each additional floor is 12 feet high, then the floor heights as we move from one floor to another we keep increasing by 12feets and forms an arithmetic progression as shown;
21, (21+12), (21+12+12), ...
21, 33, 45...
a) To write an equation for the nth floor of the tower, we will have to find the nth term of the sequence using the formula for finding the nth term of an arithmetic sequence.
The nth term of an arithmetic sequence is expressed as [tex]T_n = a + (n-1)d[/tex]
a is the first term = 21
d is the common difference = 33-21 = 45-33 = 12
n is the number of terms
Substituting the given parameters into the formula;
[tex]T_n = 21+(n-1)*12\\T_n = 21+12n-12\\T_n = 21-12+12n\\T_n = 9+12n[/tex]
Hence the equation for the nth floor of the tower is expressed as [tex]T_n = 9+12n[/tex]
b) To get the height of the 65th floor, we will substitute n = 65 into the formula arrived at in (a)
[tex]T_n = 9+12n\\T_{65} = 9 + 12(65)\\T_{65} = 9+780\\T_{65} = 789 ft[/tex]
Hence the height of the 65th floor is 789feets.

Write the equation for Chelsea's graph in
slope-intercept form. Make sure the slope is
written in simplest form.
Answer:
[tex]y=-4x+16[/tex].
Step-by-step explanation:
From the given graph it is clear that the y-intercept is 16.
The line passes through (-2,24) and (2,8). So, slope of line is
[tex]Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]Slope=\dfrac{8-24}{2-(-2)}[/tex]
[tex]Slope=\dfrac{-16}{4}[/tex]
[tex]Slope=-4[/tex]
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
Substitute m=-4 and b=16 in the above equation.
[tex]y=(-4)x+(16)[/tex]
[tex]y=-4x+16[/tex]
Therefore, the required equation is [tex]y=-4x+16[/tex].

Word Problem 18.) You are ordering T-shirts from a catalog. Each T-shirt costs $15. The cost of shipping is $6 no matter how many shirts you order. The total cost is $111. How many T-shirts did you order? please i need help!!!
Answer:
7 t-shirts
Step-by-step explanation:
Because you know the cost of shipping ($6) is constant no matter the quantity you order (fixed cost), you can subtract it from the total cost of the order to find the total variable cost. Next you divide the left over cost by the cost per t-shirt to get the quantity ordered.
$111 - 6 = $105
$105 / $15 per shirt = 7 t-shirts

Which expression could be used to calculate the volume of the new can?
Answer:
C.
Step-by-step explanation:
pi(r)^2
pi(2x+1)^2
6x(4pix^2+4pix+1pi)
24pix^3+24pix^2+6pix
Answer:
C
Explanation:
Volume for a cylinder is V= (pi)(r^2)(h)
r being radius, h being height.
The radius is 2x+1, so square that
(2x+1)^2 = 4x^2 + 4x + 1
Then multiply by 6x, the height
(4x^2 + 4x + 1)(6x) = 24x^3 + 24x^2 + 6x
Then multiply each term pi, which would be answer C.

Find the domain and range of the function represented by the graph?
A. Domain: -3
Range: -4<=y<=0
B. Domain: {-3, -2, -1, 0, 1}
Range: {-3, -2, 0, 1}
C. Domain: {-4, -3, 0, 1, 2}
Range: {-4, -3, -2, -1, 0}
D. Domain: -4 <= x<=-3
Range: 0<=y<=1
Answer:
Domain: [tex]-3\leq x\leq 1[/tex]
Range: [tex]-4\leq y\leq 0[/tex]
Step-by-step explanation:
If you find the coordinate of the graph you can get the domain and range
(-3,0), (-2,-4), (-1,-2), (0,0), (1, -4)
Now that we have that find the domain and range
Domain - x coordinate
Range - y coordinate
Domain: (-3, -2, -1, 0, 1)
Range: (-4, -2, 0)
Since the domain ranges from -3 to 1 you can use the inequality [tex]-3\leq x\leq 1[/tex] to represent the domain and [tex]-4\leq y\leq 0[/tex] for the range
