1b. 80 foot-long rope is cut into 3 pieces.

Mathematics
1 answer:
Tems11 [23]2 years ago
3 0

Answer: 53.34 feet

Step-by-step explanation:

Let the length of the second piece of rope be x.

The first piece of rope is half as long as the second piece of rope. This will be: = x/2.

The third piece is three times as long as the second piece of rope. This will be: = 3 × x = 3x

Therefore,

x + 0.5x + 3x = 80

4.5x = 80

x = 80/4.5

x = 17.78 feet

The length of the longest piece of rope will be:

= 3 × x

= 3 × 17.78

= 53.34 feet

In the set of all past due accounts, let the event A mean the account is between 31 and 60 days past due and the event B mean th
mars1129 [50]

Answer:

c. all accounts fewer than 31 or more than 60 days past due.

Step-by-step explanation:

The Universal Set is the set of all past due accounts.

Event A = the event that the account is between 31 and 60 days past due.

Event B = the event that the account is that of a new customer.

Therefore, the complement of A will be the event of all the accounts fewer than 31 or more than 60 days past due.

The correct option is C.

Which one is the better option and why need at least four sentences explaining which option is better please someone help
SCORPION-xisa [38]

9514 1404 393

Answer:

  Option B

Step-by-step explanation:

The cost of 6 turkeys at $1 per pound will be between $78 and $90. The cost of 6 turkeys at $20 each, B2G1, will be $80. We imagine that the average weight of turkeys in the 13-15 lb range will usually exceed 13 1/3 pounds, the weight at which the cost per pound is the same. That means, 6 turkeys at $1 per pound will likely cost more than $80, unless extreme effort is made to choose only the lightest turkeys.

Option B is likely to be cheaper; certainly so, if heavier turkeys are preferred.

Please help, only reply if you know answer
34kurt

Answer:

see explanation

Step-by-step explanation:

The translation represented by \left[\begin{array}{ccc}1\\4\\\end{array}\right]

interprets as a shift of 1 unit to the right ( add 1 to x- coordinate ) and a

shift of 4 units down ( subtract 4 from the y- coordinate ), then

(1, 4 ) → (1 + 1, 4 - 4 ) → (2, 0 )

(4, 4 ) → (4 + 1, 4 - 4 ) → (5, 0 )

(6, 2 ) → (6 + 1, 2 - 4 ) → (7, - 2 )

(1, 2 ) → (1 + 1, 2 - 4 ) → (2, - 2 )

Factor completely 2x^3 + 6x^2 + 10x + 30
andrezito [222]

Answer:

The factored expression is 2(x² + 5)(x + 3).

Step-by-step explanation:

Hey there!

We can use a factoring technique referred to as "grouping" to solve this problem.

Grouping is used for polynomials with four terms as a quick and easy factoring method to remove the GCF and get down to the initial terms that create the expression/function.

Grouping works in the following matter:

  1. Given equation: ax³ + bx² + cx + d
  2. Group a & b, c & d: (ax³ + bx²) + (cx + d)
  3. Pull GCFs and factors

Let's apply these steps to the given equation.

  1. Given equation: 2x³ + 6x² + 10x + 30
  2. Group a & b, c & d: (2x³ + 6x²) + (10x + 30)
  3. Pull GCFs and factors: 2x²(x + 3) + 10(x + 3)

As you'll see, we have a common term with both sides of the expression. This term, (x + 3), is a valuable asset to the factoring process. This is one of the factors for our expression.

Now, we use our GCFs to create another factor.

  1. List GCFs: 2x², 10
  2. Create a term: (2x² + 10)

Finally, we'll need to simplify this one by taking another GCF, 2.

  1. Pull GCF: 2(x² + 5)

Now that we have this term, we need to understand that this <em>could</em> also be factored further using imaginary numbers, but it is also acceptable to leave it in this form.

Therefore, we have our final factors: 2(x² + 5) and (x + 3).

However, when we factor, we place all of our terms together. This leaves us with the final answer: 2(x² + 5)(x + 3).
