NVM ITS WRONG
The first piece is 5 inches long, the second piece is 10 inches long, and the third piece is 31 inches long.
The problem involves a piece of steel that is 46 inches long and it is cut into three pieces. The wording of the problem gives us equations we can use to solve for lengths of the pieces. We're told:
We can let x represent the length of the first piece. Then the length of the second piece is 2x, and the length of the third piece is 6x+1.
Because the three pieces together form the original 46-inch piece, we can set up this equation: x + 2x + 6x + 1 = 46, which simplify to 9x +1 = 46. Solving for x gives x = 5. Therefore, the lengths of the pieces are 5 inches, 10 inches (2 * 5), and 31 inches (6 * 5 + 1).

least $200?
Answer:
27 hours
Step-by-step explanation:
So t is going to represent time. $8t is equivalent to how much she makes for t amount of time. Being she is already down $16 for the gas, we have to take that into consideration that she must earn that back. Set up:
$8t - $16 = $200
Add like terms to get:
$8t = $216
Now solve for t by dividing both sides by $8.
t = 27 hours

Answer:
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationships between triangle sides and trig functions. These abbreviations tell you that ...
Sin = Opposite/Hypotenuse ⇒ sin(x) = b/c
Cos = Adjacent/Hypotenuse ⇒ cos(x) = a/c
Tan = Opposite/Adjacent ⇒ tan(x) = b/a
Answer:
93.32% probability that the weight will be less than 4356 grams.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
If a newborn baby boy born at the local hospital is randomly selected, find the probability that the weight will be less than 4356 grams.
This is the pvalue of Z when X = 4356. So
has a pvalue of 0.9332
93.32% probability that the weight will be less than 4356 grams.
