Don Luis, el carpintero, desea construir un mueble para estantería, el cual es in- dispensable que tenga dos áreas cuadradas, donde el cuadrado mayor mida por lado, una unidad menor que el doble del largo del cuadrado menor. El área total del mueble será de 121 pies cuadrados.
Answers
Answer:
El área de un cuadrado de lado L es:
A = L*L
Y sabemos que si el cuadrado menor tiene lado de largo L, entonces el cuadrado mayor tiene lado de largo 2*L - 1ft
Área menor = L*L = L^2
Área mayor = (2L - 1ft)*(2L - 1ft)
El área total es igual a la suma de ambas áreas:
121 ft^2 = L^2 + (2L - 1ft)*(2L - 1ft) = L^2 + 4*L^2 - 2ft*L + 1ft^2
Ahora podemos resolver esto para L.
121 ft^2 = 5*L^2 - 2ft*L + 1ft^2
0 = 5*L^2 - 2ft*L - 120 ft^2.
Usando la formula de Bhaskara, las soluciones son:
[tex]L = \frac{2ft +- \sqrt{(2ft)^2 - 4*5*(-120ft^2)} }{2*5} = \frac{2ft +- 49ft}{10}[/tex]
Las dos soluciones son:
L = (2ft + 49ft)/10 = 51ft/10 = 5.1ft
L = (2ft - 49ft)/10 = -4.7 ft
Como estamos hablando de el largo de algo, la única opción que tiene sentido es la positiva.
Entonces el largo de los lados del cuadrado menor es L = 5.1 ft
El largo de los lados del cuadrado mayor es M = 2*5.1ft - 1ft = 9.2ft

Answers
Answer: x=12
Step-by-step explanation:
20 squared= 400 and 16 squared= 256. The Protagorean Theorm is a sqaured plus b sqaured equals c squared. You just reverse the Theorm to C sqaured minus B squared= A squared. 400-256=144 (12x12= 144)
x=12
Explanation:
To solve this question, we need to use the equation a^2+b^2=c^2.
A and B are the sides of the right triangle that are perpendicular to each other and C is the diagonal side. So, in this case, a=16, b=x and c=20.
1) plug values into the equation
a^2+b^2=c^2
16^2+x^2=20^2
2) expand the squares
256+x^2=400
3) Subtract both sides by 256
x^2=400-256
x^2=144
4)Square root both sides
x=12

Answers
Answer:
0.14 ohmsStep-by-step explanation:
We know that ohms law is given by the expression
V=IR
In the problem, we are given that
voltage v= 17.5volts
currents I=125 amps
Substituting our data into the expression we have
17.5=125*R
R=17.5/125
R=0.14 ohms
Hence the current is 0.14 ohms

B Yes; 1,200 is less than 2,000.
C No; 1,200 is more than the 400 he burned off at the gym.
D No; 1,200 will cause him to exceed 2,000.
Answers

D
Step-by-step explanation:
D is correct because 1,400-400= 1,000

Item 1 Find the volume of the prism. A rectangular prism with length of start fraction 4 over 5 end fraction millimeter, width of one-half millimeter, and height of start fraction 3 over 8 end fraction millimeter. The volume is $$ cubic millimeter.
Answers
Answer:
The volume of the rectangular prism is 3/20 (or 0.15) mm³.
Step-by-step explanation:
The volume of the rectangular prism can be calculated as follows:
[tex] V = l*w*h [/tex] (1)
Where:
l: is the length = 4/5 mm
w: is the width = 1/2 mm
h: is the height = 3/8 mm
By entering the values of l, w, and h into equation (1) we can find the volume:
[tex] V = l*w*h = \frac{4}{5} mm*\frac{1}{2} mm*\frac{3}{8} mm = \frac{3}{20} mm^{3} = 0.15 mm^{3} [/tex]
Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.

Which equation is true when the value of x is -12
Answers
Answer:
Which equation is true when the value of x is -12 HERE YOU GO!!
Step-by-step explanation:
tricky ... let's see ...
I notice that if we subtract xy from both sides we get
7x + xy - xy = xy - xy + 21
then
7x = 21
and
x = 21/7 = 3
so there is only one value of x that satisfies the equation
x = 3
Going back to the original equation we see that any value of y will satisfy the original equation
we can see this by rearranging things:
7x + xy - xy = 21
here, I have performed the subtraction of xy on the right side as above, but have left the left side undone
(so we don't lose the presence of y)
Note that the above can also be written as
7x + (x - x)y = 21
or
7x + 0y =21
now, since anything times zero equals zero,
y may be any number.
Let's summarize:
1) x = 3
2) y = anything
looking back at the original question;
1) the equation is true for all ordered pairs
FALSE (only one x works, not all x)
2) there are no x and y pairs for which the equation is true.
FALSE (x=3, y=anything) makes it true, i.e. (3,1)
3) For each value of x, there is one and only one value of y that makes the equation true,
FALSE for each value of x, for the one value of x, x=3, y can be any number, which is an infinite number, not one
4) for each value of y, there is one and only on value of x that makes the equation true.
TRUE!! for all the infinite values of y you may pick, there is one and only one x you may pick, x = 3
