Given that;
A carpenter bought a piece of wood that was 0.42 meters long.
And, She sawed 0.3 meters off the end.
Here,
A carpenter bought a piece of wood that was 0.42 meters long.
And, She sawed 0.3 meters off the end.
Hence, The length of piece of wood now = 0.42 + 0.3 meter
= 0.72 meters
Thus, The length of piece of wood now = 0.72 meters

0.5- 2 2/5 = 1/2y +2.4 Please help! Find the value of y! Thanks!
The value of y, given the equation, can be found to be - 8 .6
How to find the value of y ?To find the value of y, first convert the mixed fraction to a decimal for easier calculation :
2 ² / ₅ = 2 + 2 / 5
= 2 + 0. 4
= 2. 4
The equation then becomes :
0. 5 - 2.4 = 1 / 2 y + 2. 4
This can be rewritten as :
0. 5 - 2.4 = 1 / 2 y + 2. 4
0. 5 - 2 . 4 - 2. 4 = 1 / 2 y
1 / 2 y = - 4. 3
y = - 4. 3 / 1 / 2
y = - 8 .6

What is fraction?Any number of equal portions, or fractions, can be used to represent a whole. Fractions in standard English indicate how many units of a certain size there are. 8, 3/4. A whole includes fractions. The ratio of the numerator to the denominator is how numbers are expressed in mathematics. Each of these is an integer in simple fractions. In the numerator or denominator of a complex fraction is a fraction. True fractions have numerators that are less than their denominators. A fraction is a sum that constitutes a portion of a total. By breaking the entire up into smaller bits, you can evaluate it. Half of a full number or item, for instance, is represented as 12.
N = the number of dollars 2N the number of quaters.....so we have
25(2N) + 1N = 96
1.50N = 96
so, by fraction we have -
N = 96 / 1,50 = 64 dollars

For what value of a the system of linear equations Ax 3y a 3?
The system of linear equations has no solution for any value of a.
The equations Ax + 3y = a and 3x + 3y = a can be written in matrix form as
[A 3] [x] [a]
[3 3] * [y] = [a]
By using the Gaussian elimination method, the reduced form of the matrix is
[A 3] [x] [a]
[0 0] * [y] = [0]
This implies that the system has no solution for any value of a.
The system of linear equation
Ax + 3y = a and 3x + 3y = a can be written in matrix form as
[A 3] [x] [a]
[3 3] * [y] = [a]
We can use the gaussian method to solve this system. First, we subtract 3 times the first equation from the second equation to get
[A 3] [x] [a]
[0 0] * [y] = [0]
This implies that the system has no solution for any value of a.

Is the function f/x )= x x − 4 − − − − √ is continuous on the interval 4 [infinity]?
No, the function f(x) = x - √x - 4 is not continuous on the interval [4, infinity].
Here's why, A function is considered continuous if the function is defined at every point in its domain and there are no breaks or jumps in the function's graph. In this case, the function f(x) = x - √x - 4 is defined for all x > 4, However, the function includes a square root of x-4, which is defined only for non-negative real numbers, thus for x < 4, the function is undefined. Therefore, the function is not continuous on the interval [4, infinity].

The length of the rectangle is X units more than its
width. The width of the rectangle is 11 units and the
length of the wire that is used to make this rectangle
is a maximum of 57 units. Represent this situation
using an inequality.
Answer: [tex]2x+44 \le 57\\\\[/tex]
Explanation:
W = width
W = 11
L = length
L = width+x
L = 11+x
P = perimeter of the rectangle
P = 2L+2W
P = 2*(11+x)+2*11
P = 22+2x+22
P = 2x+44
The perimeter is at max 57 units because it is the length of wire used. Think of it like fencing around a piece of land. Be sure not to mix up the length of the wire with the rectangle length; those are two different things.
Anyways, because the perimeter maxes out at 57, this means either P = 57 or P < 57.
This leads to:
[tex]P \le 57\\\\2x+44 \le 57\\\\[/tex]
