Answer:

Break-even point in units= 571 hamburgers

Step-by-step explanation:

Giving the following information:

The cost of making a hamburger is 10.75 and the selling price is 16. The fixed expenses for the month are 3000.

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 3,000 / (16 - 10.75)

Break-even point in units= 571 hamburgers

Answer:

the data has 2 range

Step-by-step explanation:

you can subtract the largest number with the smallest

Answer:

Step-by-step explanation:

The data are evenly distributed with a mean of 7.1

Given:

The function is:

[tex]f(x)=4x^2-25x-21[/tex]

To find:

The domain of the given function.

Solution:

Domain is the set of input values.

We have,

[tex]f(x)=4x^2-25x-21[/tex]

It is a quadratic polynomial.

We know that a quadratic polynomial is defined for all real values of x. So, the given function is defined for all real values of x and the domain of the given function is:

Domain = Set of all real number

Domain = (-∞,∞)

Therefore, the correct option is B.

Answer:

true, unless its a check all that apply and then you can have multiple!

In other words, it's 2 feet, 3 inches

=================================================

Work Shown:

Convert the 4'1" to purely inches only

4'1" = 4 ft, 1 inch

4'1" = 4 ft + 1 inch

4'1" = 48 inches + 1 inch

4'1" = 49 inches

Note how 4 ft = 4*12 = 48 inches

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

Through similar steps, you should find that 1'10", aka 1 ft 10 inches, is equivalent to 22 inches

Subtracting the two quantities gets us

(4' 1") - (1' 10") = (49 inches) - (22 inches) = 27 inches

Now convert that to the format "feet,inches".

27 in = 24 in + 3 in

27 in = (24/12 ft) + 3 in

27 in = 2 ft + 3 in

27 in = 2 ft, 3 in

27 in = 2' 3"

Answer:

x=12. B=52

Step-by-step explanation:

In ∆BCD,

<C=45

<D=7x-1

<B=3x+16[as this diagram is a parellelogram so DE II BC so <CBD=<BDE=3x+16 bcz alternate interior angle]

interior angle of triangle=180 degree

<B+<C+<D=180

3x+16 + 45 + 7x-1 = 180

10x + 60=180

10x =180-60

x=120/10

x=12 degree

m<B =3x+16

=3(12)+16

=36+16

m<B = 52 degree

Answer:

C. 10 = 2.5 + 0.5x

Step-by-step explanation:

A. 0.5x + 2.5 = 10

B. 0.5 – 2.5 = 10x

C. 10 = 2.5 + 0.5x

D. 2.5x + 0.5 = 10

E. 2.5x – 0.5 = 10

Total distance Hector covers = 10 km

Distance he has covered = 2.5 km

Distance he covers per week = 0.5 km

Let

x = number of weeks

The equation is given by

2.5 + 0.5x = 10

It can also be written as:

10 = 2.5 + 0.5x

10 - 2.5 = 0.5x

7.5 = 0.5x

x = 7.5/0.5

x = 15 weeks

Answer:

A and C

0.5x + 2.5 = 10

10 = 2.5 + 0.5x

Answer:

5/6

Step-by-step explanation:

what you do first is find the common denominator

so that would be:

3/6 + 2/6

then you would add them

so that would be:

3/6 + 2/6 = 5/6

and 5/6 is your answer

42*6=252m^2

Answer:

See below for answers and explanations

Step-by-step explanation:

Problem 1:

A standard deck of cards contains 52 cards, consisting of 13 spades. If you select only one randomly, the probability of that occurring would be 13/52 or 1/4. Since there are only 26 red cards in a standard deck, then the probability of selecting a red card would be 26/52 or 1/2. Because the two events are independent of each other, their probabilities are multiplied. Therefore, the probability of selecting a spade, and then replacing it in hopes of drawing a red card is (1/2)(1/4) = 1/8.

Problem 2:

We are selecting a spade and then another spade while NOT replacing the first spade (remember that these events are independent of each other also). This means that the total card count will change by picking up the second card. Therefore, the probability of selecting a spade, followed by another spade, is (13/52)(12/51) = 156/2652 = 1/17.

Answer:

The largest value of x will be [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

[tex]3x-7<-2[/tex]

[tex]3\frac{5}{3}-7<-2[/tex]    

[tex]\frac{15}{3} -7<-2[/tex]      Always multiply whole number then numerator

[tex]5-7<-2[/tex]       Statement is false so that means x has to be less than 5/3

So the largest value of x will be [tex]\frac{4}{3}[/tex]

Answer:

2) (3, -2)

Step-by-step explanation:

d + e = 1

- d + e = - 5

Answer:

721.64

Step-by-step explanation:

32.7*26.3=860.01

13.7*10.1=138.37

860.01-138.37=721.64

721.64 mi^2

Step-by-step explanation:

Area of the large rectangle A2 is

A2 = (32.7 mi)(26.3 mi) = 860.01 mi^2

Area of the small rectangle A1 is

A1 = (10.1 mi)(13.7 mi) = 138.37 mi^2

Therefore, the area of the shaded region is simply the difference between A2 and A1:

Area (shaded) = A2 - A1

= 860.01 mi^2 - 138.37 mi^2

= 721.64 mi^2

Answer:

x = 8

Step-by-step explanation:

It is given that the two polygons are similar, one property of similar polygons is that if one were to multiply each side length by a certain number (referred to as the ratio of similitude), they would get the side length of the corresponding side on the other polygon. To find the ratio one has to divide the side length of one polygon by its corresponding side length in the other polygon.

30 ÷ 25 = 1.2

Set up an equation by multiplying one side length by the ratio of similitude, set it equal to its corresponding side length in the other polygon;

1.2 (35) = 4x + 10

Simplify,

42 = 4x + 10

Inverse operations,

42 = 4x + 10

32 = 4x

8 = x

Answer:

Step-by-step explanation:

Use proportions to solve this and the similarity from smaller side to corresponding larger side:

[tex]\frac{s}{l}:\frac{25}{30}=\frac{35}{4x+10}[/tex] and cross multiply to solve for x:

1050 = 25(4x + 10) and

1050 = 100x + 250 and

800 = 100x so

x = 8

Answer:

a. x = 4.8989794855663561963945681494118 or 4.9 rounded

b. x = 8.6023252670426267717294735350497 or 8.6 rounded

Step-by-step explanation:

7² - 5² = x²

49 - 25 = x

49 - 25 = 24

√24 = 4.8989794855663561963945681494118

7² + 5² = x²

49 + 25 = x

49 + 25 = 74

√74 = 8.6023252670426267717294735350497
