For this case we can make the following rule of three:
1/4 --------> 1/8
1 ----------> x
From here, we clear the value of x.
We have then:
x = (1 / (1/4)) * (1/8)
Rewriting:
x = 4 * (1/8)
x = 4/8
x = 1/2 minutes
Answer:
it takes her 1/2 minutes to write a full page
Answer:
The answer would be $179.40
Step-by-step explanation:
all you have to do is take the price of the car and multiply it by .069 (6.9% in decimal form)
I'm assuming that x is part of the data set, and, with x, the mean equals 105. To find the value of x, you must add all the data values together to get 544+x (you still don't know what x equals). Then put 544+x over how many days values there are, including x (there are 6). You should have 544+x/6. Now, as this is how you would calculate the mean if you knew what x was equal to, you must set it equal to the mean, since you know what it is (105). You should now have 544+x/6 = 105. You have your equation set up--now you just have to solve it. I would multiply by 6 on both sides to get rid of the 6 on the left side. You would then have 544+x = 630. I would finally subtract 544 from both sides to get x = 86. Your final answer is x = 86.
Longitud = L Ancho = A
2A + 2L = 54
L = 2A Sustituir este valor por L en la primera ecuación:
2A + 2(2A) = 54
2A + 4A = 54
6A = 54
A = 9
También porque L = 2A,
L = 2(9) = 18
