The area of a rectangular wall of a barn is 144 square feet. Its length is 10 feet longer than the width. Find the length and width of the wall of the barn.
The width is __feet.
Answers
Answer:
8 feet
Step-by-step explanation:
Let l and w be length and width, respectively. Then:
lw=144 and
l=w+10
So:
w(w+10)=144
w²+10w-144=0
(w+18)(w-8)=0
w=8 as the width ................
The width of the rectangular wall is 8 feet.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Let l and w be length and width, respectively. Then:
l x w=144
l = w + 10
The area will be given as;-
w(w+10)=144
w²+10w-144=0
(w+18)(w-8)=0
w = 8 and -18 ignore -18.
Therefore the width of the rectangular wall is 8 feet.

Answer:
H) Slope -1/4 and y-intercept -1.5
Step-by-step explanation:
The slope of the line is determined by the formula :
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\[/tex]
We can use any two points on the line lets use the ones that are shown, (-6 , 0) and (2 , -2).
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-2-0}{2-(-6)} \\\\m=\frac{-2}{8}\\\\m=-\frac{1}{4} \\[/tex]
and the y-intercept is shown in the graph where the line crosses the y-axis
In this case the line crosses the y-axis between -1 and -2 which is -1.5
so the value of slope is -1/4 and the value of y-intercept is -1.5 .So third option is our answer.

Answers
Answer: Se pueden hacer 196,830,000 placas distintas.
Step-by-step explanation:
Cada placa va a tener 3 letras y 4 números.
Lo primero que tenemos que hacer es contar el numero de opciones que tenemos para cada selección, donde las selecciones van a ser.
Primera letra, segunda letra, tercera letra, primer numero, etcétera.
Entonces.
Para la primera letra tenemos 27 opciones.
Para la segunda letra también tenemos 27 opciones.
Para la tercera letra también tenemos 27 opciones.
Para el primer numero tenemos 10 opciones (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
para el segundo numero también hay 10 opciones.
Para el tercer numero también hay 10 opciones.
Para el cuarto numero también hay 10 opciones.
El numero total de posibles combinaciones va a ser igual al producto de todos los números de opciones, en este caso es:
C = 27*27*27*10*10*10*10 = 27^3*10^4 = 196,830,000

the average rate of change of the function f(x) on the interval -3≤x≤3 is -2.5. If (-3)=14 then which of the following is the value of f(3)?
Answers
The average rate of change of f(x) on -3 ≤ x ≤ 3 is given to be
(f (3) - f (-3)) / (3 - (-3)) = -2.5
If f (-3) = 14, then
(f (3) - 14) / (3 + 3) = -2.5
(f (3) - 14) / 6 = -2.5
f (3) - 14 = -15
f (3) = -1

Answer:
7p¹⁵/ 3q¹²
Step-by-step explanation:
From the question given above,
28p⁹q¯⁵ / 12p¯⁶q⁷
To know which of option is equivalent to the above expression, we shall simplify the expression as shown below:
28p⁹q¯⁵ / 12p¯⁶q⁷
28p⁹q¯⁵ ÷ 12p¯⁶q⁷
Recall:
Xᵐ ÷ Xⁿ = Xᵐ ¯ ⁿ
Therefore,
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (28/12)p⁹ ¯ ¯⁶q¯⁵ ¯⁷
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p⁹⁺⁶q¯¹²
28p⁹q¯⁵ ÷ 12p¯⁶q⁷ = (7/3) p¹⁵q¯¹²
Recall:
X¯ⁿ = 1/Xⁿ
Therefore,
(7/3) p¹⁵q¯¹² = (7/3) p¹⁵ × 1/q¹²
(7/3) p¹⁵q¯¹² = 7p¹⁵/ 3q¹²
Hence,
28p⁹q¯⁵ / 12p¯⁶q⁷ = 7p¹⁵/ 3q¹²
