A chef made 1,669 hamburgers last week and 347 this week how many more hamburgers did he make last week than this week​

Answers

Therefore 1332 more hamburgers he made last week than this week.

Number of hamburgers made by chef last week = 1669

number of hamburgers made by chef this week = 347

We have to find how many more hamburgers did he make last week than this week​ as

= No of hamburgers last week - no of hamburgers this week

= 1669 - 347

= 1322

Therefore 1332 more hamburgers he made last week than this week.

1. What can you say about the value of a polynomial
when P(a)=0

Answers

Answer:

The expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0

Step-by-step explanation:

The question would be better answered if you gave option. Since there is no option, I'll answer the question generally.

Given

[tex]P(a) = 0[/tex]

The above expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0

Take for instance, the polynomial is:

[tex]P(x) = x^2 - x - 2[/tex]

And the divisor is x - 2, then P(2) = 0 because (x - 2) is a divisor of the equation.

[tex]\frac{P(x)}{x} =\frac{x^2 - x - 2}{x - 2}[/tex]

Factorize the numerator

[tex]\frac{P(x)}{x} =\frac{(x- 2)(x + 1)}{x - 2}[/tex]

[tex]\frac{P(x)}{x} =x + 1}[/tex]

See that x - 2 is a divisor

To check

Set x - 2 to 0

[tex]x -2 = 0[/tex]

[tex]x = 2[/tex]

So, we have:

[tex]P(x) = x^2 - x - 2[/tex]

[tex]P(2) = 2^2 - 2 - 2[/tex]

[tex]P(2) = 4 - 2 - 2[/tex]

[tex]P(2) = 0[/tex]

are the Lines parallel, perpendicular, or neither?

Answers

Answer:            The lines are perpendicular.

To solve, we can find the slope of each line and compare them to the qualities of parallel and perpendicular lines.

Vocabulary and SlopeParallel

The lines run in the same direction and can never meet. If the lines are parallel, they would have the same slope.

Perpendicular

The lines meet at 90°. If the lines are perpendicular, the slopes would be negative reciprocals of each other.

The negative reciprocal of a number is when we flip the fraction upside down and change the negative sign.To check this, we could multiply the two slopes together and the answer will be –1.

How to Find Slope

Use the slope formula. Slope is represented by the letter m.

[tex]\displaystyle{ m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} }[/tex]

On a graph, we write points as (x, y). To use the formula, we need two points on each line. The question already shows what points we can use.

Choose which point coordinates will be x₁, y₁ and x₂, y₂.Substitute the points into the formula.Solve.

a) Blue line

The points are (2, -7) and (6, 5). The variables can be:

x₁ = 2

y₁ = -7

x₂ = 6

y₂ = 5

Substitute into the slope formula and solve for slope.

[tex]\displaystyle{ m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} }[/tex]

[tex]\displaystyle{ m=\frac{5--7}{6-2} }[/tex]        Simplify the numerator.

[tex]\displaystyle{ m=\frac{5+7}{6-2} }[/tex]           Simplify the numerator and denominators.

[tex]\displaystyle{ m=\frac{12}{4} }[/tex]               Divide.

[tex]\displaystyle{ m=3 }[/tex]                 Solved for slope of blue line.

b) Green line

The points are (-1, 5) and (8, 2). The variables can be:

x₁ = -1

y₁ = 5

x₂ = 8

y₂ = 2

Substitute into the slope formula and solve for slope.

[tex]\displaystyle{ m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} }[/tex]

[tex]\displaystyle{ m=\frac{2-5}{8--1} }[/tex]        Simplify the denominator.

[tex]\displaystyle{ m=\frac{2-5}{8+1} }[/tex]           Simplify the numerator and denominators.

[tex]\displaystyle{ m=\frac{-3}{9} }[/tex]              Simplify the fraction.

[tex]\displaystyle{ m=-\frac{1}{3} }[/tex]              Solved for slope of green line.

Compare the Slopes

The slopes are:

[tex]\displaystyle{-\frac{1}{3}}[/tex] [tex]3[/tex], which is the same as [tex]\displaystyle{\frac{3}{1}}[/tex]

We know the slopes are not the same, so the lines are not parallel.

However, the slopes are negative reciprocals of each other. The fraction is flipped and the negatives are different.

If we multiply the slopes together, we would get –1:

[tex]\displaystyle{-\frac{1}{3}*\frac{3}{1}=-1}[/tex]

∴ The lines are perpendicular.

5. Mr. Franklin needs to purchase 60 AA batteries. A nearby store sells a 20-pack of AA batteries for $12.49 and a 12-pack of the same batteries for $7.20. Would it be less expensive for Mr. Franklin to purchase the batteries in 20-packs or 12-packs? What is the difference between the costs of one battery from each pack?

Answers

Answer: See explanation

Step-by-step explanation:

A nearby store sells a 20-pack of AA batteries for $12.49. Therefore, the cost of 1 pack will be:

= $12.49 / 20

= $0.6245

The store also sells a 12-pack of the same batteries for $7.20. The cost per pack will be:

= $7.20 / 12

= $0.6

Therefore, it will be less expensive for Mr. Franklin to purchase the batteries in 12 packs.

The difference between the costs of one battery from each pack will be:

= $0.6245 - $0.60

= $0.0245

Answer:

$0.0245

A sales associate at an electronics store earns 9.5% commission on her total yearly sales. Last year, the sales associate earned an income of $11,875. What is the total amount of sales that the associate made last
year?

Answers

The total amount of sales made by the associate last year is $124,000.

What is defined as the percentage?

The term percent means "out of every hundred" or "per hundred."

The term is based on the Latin phrase per centum, which means "by the hundred." So, for every 100 units of something, a single percent represents one of those hundred units, or one percent.To calculate a percentage, divide the fraction of the total by the total but also multiply by 100.

Now, as per the given question;

Let the total sales done by the associate in last year is 'x'.

The commission earned on the total sales is 9.5%

Thus, 9.5% of x can be written as;

= (9.5×x)/100

The total earning from the sales is $11,875.

Thus,

(9.5×x)/100 = 11,875

Simplify the equation to find x.

x = (11,875×100)/9.5

x = 125,000

Therefore, the total sales done by the commissioner in last year was $125,000.

Of the eight teachers at Jackson Middle School, 4 are female and 4 are male. Four of the teachers will be selected at random to lead a student field trip. What is the probability that all of the teachers selected will be female?

Answers

Answer:

1/16

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Number of event/ Total outcome of sample space

Since there are 8 teachers in a school, the Total outcome = 8

If four of the teachers will be selected at random to lead a student field trip,

Probability of selecting first female teacher = 4/8 = 1/2

Probability of selecting 2nd female teacher = 4/8 = 1/2

Probability of selecting 3rd female teacher = 4/8 = 1/2

Probability that all of the teachers selected will be female = 1/2* 1/2* 1/2* 1/2

Probability that all of the teachers selected will be female = 1/16

Graph the line 3y - 2x = 3 on the axes provided. Determine and state the slope and the
y-intercept of each line. Graph the line y=5. State the coordinate of the intersection.

Answers

Answer:

You can find the answer in the graph below.

Step-by-step explanation:

3y - 2x = 3

x- int = (-1.5,0)

y-int = (0,1)

slope = 2/3x

-----------------------------

y=5 and 3y - 2x = 3  intersection is on (6,5)

----------------------

y=5 : y-int : (0,5)

The slope of the given line is 2/3 and the y-intercept of the given line is (0, 1). The coordinate of the intersection of two lines is (6, 5).

The equation of the line is 3y-2x=3.

In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

The slope intercept form of the given equation is

3y=2x+3

y=2/3 x+1

Here, the slope of a line = 2/3 and the y-intercept of a line = (0, 1).

The graph of the line y=5, is attached below.

From the graph, the coordinate of the intersection is (6, 5).

Therefore, the slope of the given line is 2/3 and the y-intercept of the given line is (0, 1). The coordinate of the intersection of two lines is (6, 5).

Answers

Answer:

98 - 24√3 is your answer dear.

Step-by-step explanation:

Let the length of broken part of the tree = 14 - x

For finding x

sin60° = √3/2 = x /14-x

14√3 - √3x = 2x

14√3 = 2x + √3x

14√3 = (2 + √3)x

x = 14√3/(2 + √3)x

after rationalisation

x = 24√3 - 84

substract it 14 - (24√3 - 84)
