At a trout farm, most of the trout have a length of 23.5 cm. The length of some differ from this by as much as 2.1 cm. Write and solve an absolute-value inequality to find the range of lengths of the trout.
Answers
Answer:
21.4 ≤ x ≤ 25.6
Step-by-step explanation:
The absolute value of a number is the non-negative value of the number without regard to its sign.
The absolute value of a real number x (|x|) is x for x is positive and -x for x is negative.
Let x represent the length of the trout. Since most trout have a length of 23.5 cm and differ by 2.1 cm, then x can be represented by:
|x - 23.5| ≤ 2.1
x - 23.5 ≤ 2.1 or -(x - 23.5) ≤ 2.1
x ≤ 2.1 + 23.5 or x - 23.5 ≥ -2.1
x ≤ 25.6 or x ≥ 21.4
Hence, the range of lengths of the trout is 21.4 ≤ x ≤ 25.6

Which is the best description of the equivalency of the two expressions?
Expression 1
5x-2x-4+6x+3
Expression 2
6x-6x+6-x+10x-7
O The two expressions are not equivalent because when x2, the two expressions do not have the same value.
O The two expressions are not equivalent because when they are simplified, they do not have the same coefficients for
the andx terms.
O They are equivalent because the sum of the constants is the same in both expressions.
O They are equivalent because when X- 2, the two expressions have the same value,
Answers
Once you’ve done this you can see that the two expressions are actually the same and therefore equal to each other.
The best description of the equivalency would be D
Just because the sum of the constants are equal doesn’t mean the expressions are. There could be different amounts of the variable (that’s why you should always simplify )

Answers
Answer:
Answer:
1). Option (A)
2). Option (A)
Step-by-step explanation:
1). A worker bee has the mass = 0.00011 kg
In scientific notation we can convert the mass of bee as,
0.00011 =
=
Since 1.1 ≈ 1,
Therefore, 1.1 × 10⁻⁴ ≈ 1 × 10⁻⁴ kg
Option (A) is the answer.
2). An African elephant has a mass = 8139 kg
In scientific notation,
8139 = 8.139 × 10³
Since, 8.139 ≈ 8
Therefore, 8139 kg = 8.139 × 10³ kg
Option (A) is the answer.

The vertex is located at (-1,-9)
The graph has y-intercepts at (-4.0) and (2.0).
The graph has a minimum.
The graph has zeros of -4 and 2.
The solution of the quadratic function represented by the graph is (-1,-9).
The graph has a maximum.
Answers
Answer:It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
Step-by-step explanation:
The Y intercept of a straight line is simply where the line crosses the Y axis.
Example
Y intercept
In the above diagram the line crosses the Y axis at 1.
The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..

jester has a piece of wood measuring 1 and 2/3 m.he needs to cut in pieces measuring 3/4 m long.how many pieces of wood did jester cut
Answers
Answer:
2 pieces
Step-by-step explanation:
Given
[tex]Length = 1\frac{2}{3}m[/tex]
[tex]Pieces = \frac{3}{4}m[/tex]
Required
Determine the number of pieces
To do this, we simply divide the length of the wood by the length of each piece.
[tex]Number = \frac{Length}{Pieces}[/tex]
[tex]Number = 1\frac{2}{3}/\frac{3}{4}[/tex]
Convert fraction
[tex]Number = \frac{5}{3}/\frac{3}{4}[/tex]
Change sign to *
[tex]Number = \frac{5}{3}*\frac{4}{3}[/tex]
[tex]Number = \frac{20}{9}[/tex]
[tex]Number = 2.2222[/tex]
[tex]Number = 2[/tex] (approximated)

To get maximum product we need to optimize how we break down the numbers
Its obvious we don't want number 1 to be used as it won't change the product
Also we don't want to use big numbers, we can have four 5's instead of two 10's as it would give greater product, 5*5 > 10
What is best number?
2 and 3 are the smallest, 4 can be written as two 2's5 = 2+ 3 and 2*3 = 6, so it is better to use 2's and 3's instead of 56 = 2+2+2, 2^3 = 8 and 6 = 3+ 3, 3^2 = 9, so it is better to use two 3's for 67 = 2+2+3, 2*2*3= 12, again 2's and 3's make greater productSo the best is to break the number down to 2's and 3's
23 = 2*10 + 3 ⇒ 2^10*3 = 307223 = 3*7 + 2 ⇒ 3^7*2 = 4374As we see the maximum product we can get is 4374 with seven 3's and one 2.

What is the sale price of your ticket? Explain how you

Answers
Answer: I do not know
Step-by-step explanation:
Answer: 9.22 (This is rounded)
Step-by-step explanation:
20% off of 10.90 is 2.18. So, you subtract that from 10.90 and you get 8.72. Then, you find the tax rate which is 0.5014. When you round it, you should get 0.50. After that, you add it to 8.72 since it’s the tax. That then gets you 9.22.
