Answer:
25/64
Step-by-step explanation:
To get this answer, first you need to use the distributive property:
(-3/8)(-5/8) - (1/4)(-5/8)
Next, multiply:
15/64 - (-5/32)
Change the negative signs into a positive sign:
15/64 + 5/32
Multiply 5/32 by 2 on both top and bottom:
15/64 + (5)(2)/(32)(2)
You will then get:
15/64 + 10/64
Now, add the numerators. You will get:
25/64
This is your answer. I hope it helped!
Simetría Traslacional
En este caso la imagen no se refleja, ni gira alrededor de una eje, sino que más bien es como si se multiplicara el objeto que aparece en ella, como ocurre por ejemplo con la siguiente fotografía.
si calculamos y planteamos todo lo dicho tendremos que:
AR=360/3=120
ojo:tambien se puede venir los calculos del cuadro de simetria y solo cuando se te presenta una sametrica indiguididuil bueno asi yo lo llamo espero te halla servido
Let's give the variable that you are trying to answer for a symbol. Let's call it X.
X = the amount of money both Greg and Thomas had in October
We know that in November, Greg added $120 to his account. So, Greg's account has: X + 120
We know that Thomas increased the money in his account by 20%, so Thomas' account has: X + 0.2X, or 1.2X
We know that these two amounts are equal:
X + 120 = 1.2X
Solve for X:
X + 120 - X = 1.2X - X
120 = .2X
120 / .2 = .2X / .2
600 = X

Answer:
t = ln(0.5)/-r
Step-by-step explanation:
The decay rate parameter is missing. I will assume a value of 4% per day.
The exponential decay is modeled by the following equation:
A = A0*e^(-r*t)
where A is the mass after t time (in days), A0 is the initial mass and r is the rate (as a decimal).
At half-life A = A0/2, then:
A0/2 = A0*e^(-0.04*t)
0.5 = e^(-0.04*t)
ln(0.5) = -0.04*t
t = ln(0.5)/-0.04
t = 17.33 days
In general the half-life time is:
t = ln(0.5)/-r
