1/3+1/5= 8/15 explanation-

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD this is basically multiplying each fraction by 1.Complete the multiplication and the equation becomes. The two fractions now have like denominators so you can add the numerators.

This fraction cant be reduced Therefore - 1/3+1/5=8/15

Answer:

the LCM of 105, 126, and 147 is 18420.

Since the fruit boxes need to be equally packed and no fruit is left, the largest possible number of fruit boxes needed is 18420/105 = 176 fruit boxes.

Step-by-step explanation:

To find the largest number of fruit boxes needed, we need to find the least common multiple (LCM) of 105, 126, and 147.

[The least common multiple is the smallest number that is a multiple of all the given numbers. One way to find the LCM of three numbers is to first find the LCM of two of the numbers, and then find the LCM of the result with the third number.]

To find the LCM of 105 and 126, we can list the multiples of each number and look for the smallest number that is a multiple of both:

Multiples of 105: 105, 210, 315, 420, 525, 630, 735, 840, 945, 1050, 1155, 1260, ...

Multiples of 126: 126, 252, 378, 504, 630, 756, 882, 1008, 1134, 1260, 1386, 1512, ...

The smallest multiple that both 105 and 126 share is 1260. Therefore, the LCM of 105 and 126 is 1260.

Now we can find the LCM of 1260 and 147 by finding the smallest multiple of 1260 that is also a multiple of 147:

Multiples of 1260: 1260, 2520, 3780, 5040, 6300, 7560, 8820, 10080, 11340, 12600, 13860, 15120, ...

Multiples of 147: 147, 294, 441, 588, 735, 882, 1029, 1176, 1323, 1470, 1617, 1764, ...

The smallest multiple that both 1260 and 147 share is 18420. Therefore, the LCM of 105, 126, and 147 is 18420.

Since the fruit boxes need to be equally packed and no fruit is left, the largest possible number of fruit boxes needed is 18420/105 = 176 fruit boxes.

Zach's response correctly shows combining the like terms, 2e's, and giving the remaining 2 as it is.

What is a simplification of an algebraic expression?

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easily with calculations and solving.

Zach simplifies the expression correctly because 2e + 2e + 2e = 6e with 2 left over.

The expression given "2+2+2+e+e+" is a mix of numerical constants and a variable, e. The correct simplification of this expression would be to combine like terms.

Like terms are terms that have the same variable raised to the same exponent.

In this case, 2's can be combined to give 6 and e's can be combined to give 2e. Adding 2 with 6 or 2e won't be correct as 6 and 2e are not like terms.

Hence, Zach's response correctly shows combining the like terms, 2e's, and giving the remaining 2 as it is.

It looks like you are trying to find the values of a, b, c, d, e, and f in the matrix [-3x+3y] given the matrices X and Y.

To find the values of a, b, c, d, e, and f, you will need to perform matrix multiplication. Here is how you would do this:

[-3x+3y] = [-3X+3Y]

= [-3*[-7 7]+3*[5 1]]

= [-3*[-7 7]+3*[5 1]]

= [-3*[-7 7]+3*[5 1]]

= [-3*[-7 7]+3*[5 1]]

= [-3*[-7 7]+3*[5 1]]

= [[-21 21] [9 -3]]

Therefore, the matrix [-3x+3y] is equal to [[-21 21] [9 -3]].

The price of each advanced tickets sold  is; $35

The price of each same day tickets sold is; $25

Let x be the cost of each advanced tickets sold

Let y be the cost of each same day tickets sold

We are told that for one performance, 25 advance tickets and 20 same-day tickets were sold. Thus;

x + y = 60  ------(1)

The total amount paid for the tickets was $1325 and as such, we have;

20x + 25y = 1325   ------(2)

Make x the subject in eq 1 to get;

x = 60 - y

Put (45 - y) for x in eq 2 to get;

20(60 - y) + 25y = 1325

1200 - 20y + 25y = 1325

The inequality which correctly represents the graph as represented in the task content is; y ≤ ( -1/4 ) x + 2.

First, to determine the inequality which represents the graph given, it is important to determine the equation of the border line as follows;

Since the slope formula is; m = (y₂ - y₁) / (x₂ - x₁).

Hence, given points; ( 0, 2 ) and ( 4, 1 ).

Slope, m = ( 1 - 2 ) / ( 4 - 0 )

m = -1 / 4 and y-intercept = 2.

Therefore, it follows from the slope-intercept form equation; y = mx + c that the equation of the boundary line in discuss is;

y = ( -1/4 ) x + 2.

On this note, since the region shaded on the graph is the region below the boundary line and the boundary line is a solid line;

It follows that the required inequality which the graph represents is; y ≤ ( -1/4 ) x + 2.

The work done by a force [tex]$\overrightarrow{\mathrm{F}}=(\hat{\mathrm{i}}+2 \hat{\mathrm{j}}+3 \hat{\mathrm{k}}) \mathrm{N}$[/tex], to displace a body from position A to position B is 5j

Now basically here we, are talking about the work done by a body in the form of displacement.

This displacement is done due to the force that acted upon the body.

To calculate the work done we use the formula as,

W = F.ds

where F is the force acted on the body and the 'ds' is the displacement vector or the factor,

thus we calculate 'ds' as

AB vector = r2 - r1

AB = (2i + 2j +3k ) - ( i+3j+k)

so we get as,

AB = i -j +2k

now substituting in the formula we get as

W = (i + 2j + 3k ) .(i - j +2k)

W = 1 -2 +6

W = 5 joules

Work done = 5 J

The complete question is,

The work done by a force [tex]$\overrightarrow{\mathrm{F}}=(\hat{\mathrm{i}}+2 \hat{\mathrm{j}}+3 \hat{\mathrm{k}}) \mathrm{N}$[/tex], to displace a body from position A to position B is : [The position vector of A is [tex]$\overrightarrow{r_1}=(\hat{i}+3 \hat{\jmath}+\hat{k}) \mathrm{m}$[/tex] and the position vector of B is [tex]$\left.\overrightarrow{r_2}=(2 \hat{i}+2 \hat{j}+3 \hat{\mathbf{k}}) \mathrm{m}\right]$[/tex]

Answer:

the value of p is £3.67.

Step-by-step explanation:

(a) To determine the value of p, we need to use the information given in the problem to set up and solve a simple equation. The cost of the repair at one house was £71, and it took 3 hours, so the cost per hour was £71 / 3 = £<<71/3=23.67>>23.67 per hour. The engineer charges £20 plus £p per hour, so £23.67 per hour is equal to £20 + £p. Subtracting £20 from both sides gives us £p = £3.67. Therefore, the value of p is £3.67.

(b) The formula for the cost, £C, of a repair that takes x hours can be written as: £C = £20 + (£p * x). This formula states that the cost of the repair is equal to the fixed cost of £20, plus the cost per hour (£p) multiplied by the number of hours (x) that the repair takes.

(c) To determine how long a repair that costs £96.50 takes, we can use the formula from part (b) and solve for x. Substituting in the known values, we get: £96.50 = £20 + (£3.67 * x). Subtracting £20 from both sides gives us: £76.50 = (£3.67 * x). Dividing both sides by £3.67 gives us: x = 20.89 hours.
