The maximum possible length of ribbon left on the roll is 24.5 m.

Find bounds, Roll

30 → nearest half metre.

0.5 ÷ 2 = 0.25

LB = 30 – 0.25 = 29.75

GB = 30 + 0.25  = 30.25

Piece

5.8 →  nearest 10cm or 0.1m

(10÷100=0.1)

0.1÷2 = 0.05

LB = 5.8 – 0.05 = 5.75

GB = 5.8 + 0.05 = 5.85

Max length left = GB roll – LB piece

=30.25 – 5.75

8z^3+z^2+3z-1/z-1 you can use long division to get 8z^2+(9z^2+3z-1)/(z-1). You can keep dividing this equation until you get 8z^2+9z+12+11/z-1.

By using synthetic division, you can divide it into

1 -1. 8 1 3 -1 (a.k.a their coefficients)

Then bring the 8 down three, 1 down two, and 3, down one. Take that and multiply the one by each, and put it down. 8, 1, and 2. Then, do that with -1, to get -1, -2, and 1. So, the answer is 8z^2+9z+12+11+z-1. But since it's division, and there are 4 terms on one side, and 2 terms on the other, you have to divide it so it's 8z^2+9z+12+11/z-1.

Step-by-step explanation:

Hello!

Simplify the expression by combining like terms.

The simplified expression is 4.

The simplified form of the given expression is 4.

To solve the expression 10y + 12 - 7y - 8 - 3y,

We need to combine like terms and simplify.

Simplify the expression by combining the like terms (the terms that have the same variable and the same exponent).

We have 10y, -7y, and -3y,

Which can be combined to give us a total of 0y.

This means that the variable y has been eliminated from the expression.

Combine the constant terms (the terms that don't have a variable or that have a variable raised to the power of 0).

We have 12 and -8, which can be combined to give us 4.

So, the simplified expression is 4.

We can express this mathematically as follows:

10y + 12 - 7y - 8 - 3y = (10y - 7y - 3y) + (12 - 8)

                                 = 0y + 4 = .

In other words, the expression simplifies to the constant term 4.

Step-by-step explanation:

-

Independent events are the ones whose occurrence is unrelated to any other event.

Dependent events include those that are dependent on previous events.

If the probability of an event A occurring is not impacted by the occurring of some other event B, then A & B are referred to as independent events.

Consider the example of a die roll. If A is the event 'the number appearing is odd' and B is the event 'the number showing up is a multiple of 3,'

P(A) = 3/6 = 1/2

P(B) = 2/6 = 1/3

A and B are also the events 'the number showing up is odd & a multiple of 3', implying that;

P(A ∩ B) = 1/6

P(A│B) = P(A ∩ B)/ P(B) = 1/2

Then P(A) = P(AB) = 1/2, implying that the happening of event B has had no effect on the probability of occurring of event A.

Dependent events include those that are dependent on previous events. The outcomes of previous events have an impact on these events. Dependent events are two or maybe more events that are dependent on one another.

When two events, A and B, are interdependent, the probability of their occurrence is:

P(A and B) = P(A) · P(B|A)

The pieces of cake that Jeff will eat in 1 hour is 3

The pieces of cake that Gene will eat in 1 hour is 4

The pieces of cake that Mike will eat in 1 hour is 5

It will take Mike, Gene, and Jeff more than 1 hour to each eat the cake

In order to determine the pieces of cake that Jeff can eat in 1 hour, divide 6 by 2.

6/2 = 3 pieces of cake

In order to determine the pieces of cake that Gene can eat in 1 hour, multiply 2 pieces of cake by 2.

Using proportions, the costs are given as follows:

a) Total Labor Cost: $2,505,600.

b) Total Product Cost: $1,950,000.

c) Total Cost = $4,455,600.

d) Cost per home = $461.77.

e) Cost per week = $99,013.33.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For item a, the labor cost is found using the earnings of the workers, as follows:

45 weeks x 5 days x 8 hours x 58 per hour x (12 + 8 + 4 workers)

Hence:

Total Labor Cost = 45 x 5 x 8 x 58 x 24 = $2,505,600.

For item b, the product cost is the cost of the boards, hence:

(175 + 150 + 50 boards) x 5,200

Total Product Cost = 375 x 5,200 = $1,950,000.

For item c, the total cost is the sum of the product cost and the labor cost, hence:

Total Cost = 2,505,600 + 1,950,000 = $4,455,600.

For item d, the cost per home is found dividing the total cost by the 9,649 homes, hence:

Cost per home = 4455600/9649 = $461.77.

For item e, the cost per week is found dividing the total cost by the 45 weeks, hence:

Cost per week = 4455600/45 = $99,013.33.

= 16 a^6=16a divide for 16

a^6=a there are only two solutions 1 and 0 cause:

1^6=1 and 0^6=0

16 = -4(-3) + 4 is an equation in slope-intercept form for the line passing through points (-4,16) and (3,-5)

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope.

We have been asked to write an equation in slope-intercept form for the line passing through (-4,16) and (3,-5)

First we will find the slope(m)

We know that slope = m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

For the pairs of points (-4,16) and (3,-5)

⇒ m = [tex]\frac{-5- 16}{3 - (-4)}[/tex]

⇒ m = [tex]\frac{-21}{7}[/tex]

⇒ m = -3

We know that the equation for slope(m) and y - intercept(b) of a line is given by :

y = mx + b

Here lets take equation 16 = -4(-3) + b .Here x and y is substituted with the second two points.

⇒  16 = -4(-3) + b

⇒  16 = 12 + b

⇒  b = 16 - 12

⇒  b = 4

The equation in the slope intercept is as follows:-

In Δ JLP, m ∠ JMP = 3x - 6, JK = 3y - 2, and LK = 5y - 8 then the value of LK = 7.

The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution. It is sometimes referred to as "the middle" value in a data set.

The middle number is discovered by sorting all data points and selecting the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).

Since [tex]$\overline{P K}$[/tex] is a median, JK = KL.

3y - 2 = 5y - 8

simplifying the above equation, we get

The measures of the sides of ΔXYZ are XY = 10.6, YZ = 11.2, XZ =  6.7 and the triangle XYZ must be an acute triangle

In this questions we have been given the the coordinates of the triangle XYZ.

X(-5, 9), Y(2, 1), Z(-8, 3)

We need to find  the measures of the sides of ΔXYZ .

We find the the measures of the sides using distance formula.

XY = √[(1 - 9)² + (2 + 5)²]

XY = √[-8² + 7²]

XY = √(64 + 49)

XY = √(113)

XY = 10.6

Now side YZ

YZ = √[(3 - 1)² + (-8 - 2)²]

YZ = √[(2)² + (-10)²]

YZ = √4 + 100

YZ = √104

YZ = 11.2

And the length of side XZ would be,

XZ = √[(3 - 9)² + (-8 + 5)²]

XZ = √(-6² + -3²)

XZ = √(36 + 9)

XZ = √45

XZ = 6.7

We find the sum of the squares of the two smaller sides, and compare the sum to the square of the largest side.

the sum of the squares of the two smaller sides is,

= 6.7² + 10.6²

= 44.89 + 115.54

= 160.43

= 12.67²

And 11.2² = 125.44

Since the sum of the squares of the two smaller sides is greater than the square of the largest side, the triangle must be an acute triangle.

Therefore, the measures of the sides of ΔXYZ are XY = 10.6, YZ = 11.2, XZ =  6.7 and the triangle XYZ must be an acute triangle
