there are 657 lights on your set. on any given day 6 of them burn out and need to be replaced. if each cost $45 how. much do you spend replacing them each week ?

Answer:

11

Step-by-step explanation:

Since Farmer Tim has one of each coin, 50+20+10+5=85 cents are accounted for, leaving 395 - 85 = 310 cents for the remaining coins. We can try minimizing the number of coins that add up to 310 cents by using as many large denominations as possible.

The largest denomination is 50 cents, so we can take six 50 cent coins, which add up to 6 times 50 = 300 cents. We then can take one 10 cent coin. Thus, we have a combination of seven coins that up to 310 cents.

Therefore, the smallest number of coins that Farmer Tim could have is 4 + 7 = 11.

Answer:

x=72 and the exterior angle is 154

Step-by-step explanation:

We will call the unknown angle in the triangle y.  Angle y and the angle (2x +10) form a straight line so they make 180 degrees.

y + 2x+10 =180

Solve for y by subtracting 2x+10 from each side.

y + 2x+10 - (2x+10) =180 - (2x+10)

y = 180-2x-10

y = 170-2x

The three angles of a triangle add to 180 degrees

x+ y+ 82 = 180

x+ (170-2x)+82 = 180

Combine like terms

-x +252=180

Subtract 252 from each side

-x+252-252 = 180-252

-x = -72

Multiply each side by -1

-1*-x = -72*-1

x=72

The exterior angle is 2x+10.  Substitute x=72 into the equation.

Step-by-step explanation:

176/88 = 2

Answer:

Step-by-step explanation:

First find 2 points on the line.  To do this you will need to substitute numbers in for x and y.  Do this by first putting 0 in for x to find the value of y:

9(0) + 4y = -36

0 + 4y = -36       =  4y = -36   =        y = -36 ÷ 4 = -9     y= -9

(0,-9)

Now that we have that point substitute 0 in for y.

9x + 4(0) = -36

9x + 0 = -36   =    9x = -36     =    x = -36  ÷ 9    x = -4

(-4,0)

After you have your two points decide which on you want to be (x1,y1) and which you want to be (x2,y2).  It doesn't matter which one you choose.  You will then plug in your numbers into the slope formula:

       y2 - y1           -9 - 0         -9           The slope is - 9/4

       x2 - x1            0 - 4          -4            

Let us assume that it is 1/8 lb packages of fudge.

So, the question is how many 1/8 lbs of fudge can be sold from 7 pounds of fudge

Answer:

Total amount of fudge = 7 pounds

Portions of division = 1/8 pounds

So, number of packages that can be made from 7 pounds are =

[tex]\frac{7}{\frac{1}{8}}[/tex]

= [tex]7\times8=56[/tex]

Hence, 56 packages of 1/8 lbs each can be made from 7 pounds fudge.

Answer:

B

Step-by-step explanation:

Put the second y into the first equation

3x + y = 10                           substitute for y

3x + 6x + 1 = 10                    Combine like terms on the left

9x + 1 = 10                             Subtract 1 from both sides

9x = 10 - 1                              Combine the right.

9x = 9                                    Divide by 9

x = 9/9                                   Divide

x = 1

The answer is right there. Only B is possible

y = 6x + 1

y = 6(1) + 1

y = 6 + 1

y = 7

Answer: 3 days

Step-by-step explanation: It would take 3 days for seven hens to 7 lay eggs because each hen lays an egg each day.

1 hen/1 egg = 3 days

7 hens/7 days = 14 eggs

7 hens/3 days = 7 eggs

Answer:

3 days

Step-by-step explanation:

Three hens lay 3 eggs in 3 days

We have to find the days in which 7 hens lay 7 eggs

Hen/egg=[tex]\frac{3}{3}[/tex]

Hen/egg=1

Using unitary method

1 hen lays 1 egg in 3 days

1 hen lays in 1 day =[tex]\frac{1}{3}[/tex]eggs

7 hens lay 7/3 eggs in 1 day

7 hens lay 1 egg=[tex]\frac{3}{7}[/tex]days

7 hens lay 7 eggs=[tex]\frac{3}{7}\times 7[/tex]

7 hens lay 7 eggs=3 days

Hence, 7 hens lay 7 eggs in 3 days

Answer:

A factor of 24 is a number that can be multilied by another number (normally whole (not fraction or decimal) numbers) so a factor must be less than the number any multiple of 2 greater than 24 will work so just any even number greater than 24 exg 26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60, and so on.

Step-by-step explanation:

Not all multiples of a number are its factors. In the case of the number 24, only the multiples that can divide evenly into 24, which include 1, 2, 3, 4, 6, 8, 12, and 24, can be considered its factors. Higher multiples like 48, 72 or 96 are not factors as they do not divide into 24.

In mathematics, the multiples of a number are obtained by multiplying that number by any integer. The factors of a number, on the other hand, are the numbers that you can evenly divide into that number. Therefore, for the number 24, its multiples include 24, 48, 72, 96, and so on.

However, not all multiples of 24 are factors of 24. A factor must divide into 24 with no remainder, which isn't the case with greater multiples of 24. For instance, 48, 72, 96 etc. are multiples of 24, but they are not factors of 24 because they cannot divide evenly into 24.

The ratio is 1:3

Step-by-step explanation:

People can do this in different ways.

Firstly, set some variables for cydlinder A:

Diameter = 18

Height = 1

Radius = 18 ÷ 2 = 9

Area of a cylinder is [tex]\pi r^{2} h[/tex]

Plug values in:

[tex]\pi 9^{2} 1[/tex] = 81π

Diameter = 18 ÷ 3 = 6

Height = 1 * 3 = 3

Radius = 6 ÷ 2 = 3

[tex]\pi3^{2}3  = 27\pi[/tex]

Cylinder b is 3 times less than cylinder a:

81π ÷ 27π = 3

So that means three lots of cylinder b is equal to one of cylinder a.

Step-by-step explanation:

The simplified expression for (m+13)-(p+25) is m - p - 12.

To simplify the expression (m+13)-(p+25), we can distribute the negative sign to both terms inside the parentheses:

[tex]\[m + 13 - p - 25.\][/tex]

Next, combine like terms by grouping the variables (m and -p) and the constants (13 and -25):

[tex]\[m - p + 13 - 25.\][/tex]

Now, simplify the constants:

[tex]\[m - p - 12.\][/tex]

So, the final answer is m - p - 12. This expression represents the simplified form of the given algebraic expression.

In the original expression, (m+13)-(p+25), we subtracted the entire quantity (p+25) from (m+13). Distributing the negative sign, we subtracted p and 25 individually. Combining like terms involved combining the variables (m - p) and constants (13 - 25). The final result is m - p - 12, where m and p are coefficients of the respective variables, and 12 is the simplified constant term.

In summary, the expression (m+13)-(p+25) simplifies to m - p - 12 by applying the principles of combining like terms and distributing the negative sign. This simplified form is a more concise representation of the original expression.

Answer:

25/w = l

Step-by-step explanation:

We know that the formula for the area of a rectangle is

A = l*w

We know the area is 25

Substituting this into the equation

25 = l*w

We are to solve for l, by dividing each side by w

25/w = lw/w

25/w = l

To find the length (L) of a rectangle when the area (A) is 25 square inches, you use the formula L = A/W, substituting A with 25 and W with the given width.

To solve for the length (L) of a rectangle with a known area (A), you first need the formula for a rectangle's area, which is A = L × W, where L is the length and W is the width of the rectangle. Given that the area (A) is 25 square inches and the area formula has been incorrectly stated as A = 2LW, we should correct it to A = LW.

If you have a specific width (W), you can rearrange the formula to solve for L by dividing both sides by W, resulting in L = A/W.

Using an example, if we know the width (W) is 5 inches, we could substitute into the formula:

L = A/W

L = 25 in2/5 in = 5 in

Therefore, the length (L) of the rectangle would be 5 inches.

Answer:

The equation of the line would be y = 5/4x - 4

Step-by-step explanation:

To find the equation of any line, start by finding the slope using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-4 - 1)/(0 - 4)

m = -5/-4

m = 5/4

Now that we have the slope, use that and either point to get the equation of the line

y - y1 = m(x - x1)

y + 4 = 5/4(x - 0)

y + 4 = 5/4x

y = 5/4x - 4

The equation of the line would be y = (5/4) x - 4. Hence, option B is correct.

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

To find the equation of any line, start by finding the slope using the slope formula.

m(slope) = (y₂ - y₁)/(x₂ - x₁)

m = (-4 - 1)/(0 - 4)

m = -5/-4

m = 5/4

Now that we have the slope, use that and either point to get the equation of the line.

y - y₁ = m(x - x1)

y + 4 = 5/4(x - 0)

y + 4 = 5/4x

y = 5/4x - 4

Final answer:

The equation for the altitude passing through point B(4,4) is in standard form as 11x - 3y = 32. This was found by calculating the slope of AC, finding the perpendicular slope, and then applying it with point B to find the equation of the line.

Explanation:

To find the equation of the altitude that passes through point B(4,4) of the triangle ABC with vertices A(-4,-2), B(4,4), and C(18,-8), we need to determine the slope of line AC and then find the perpendicular slope that passes through B.

Firstly, we calculate the slope of AC:

The slope of the altitude will be the negative reciprocal of the slope of AC because the altitude is perpendicular to AC. Hence,

Now we use the point-slope form of the equation of a line using point B:

Rewriting in standard form (Ax + By = C), we get:

So, the standard form of the equation of the altitude passing through point B is 11x - 3y = 32.

The width is 3 2/5  as an improper fraction  = (5*3+2)/5 = 17/5

A = l*w

17/2 = l* 17/5
