An orchard has 672 apple trees. The number of rows exceeds the number of trees per row by 4. How many trees are there in each row?

Answer:

1) 62.5%

2) 8-x/8=y/100 (where y is the percent)

Step-by-step explanation:

1) so there’s 8 questions in total cause each question si 5 points and 40 points is the max so 40/5=8

write a proportion where 8-3/8=y/100 (it’s 8-3 because it’s total question minus the wrong questions and you’ll get the remaining points and put it over a hundred since the max score you can get is a hundred.

so 5/8= y/100

cross multiply

500=8y

Divide 8 on both sides

you’ll get 62.5

2) Jist use the equation 8-x/8=y/100

( where x is the wrong amount of questions and y is the total percent)

Answer:

1st Question the answer is 25/40

2nd Question the answer is 40-(x*5)=answer

Step-by-step explanation:

1st Answer: Multiply 3 questions by 5 points and subtract that answer from 40 and that gives us the final answer -25-

90 degrees.

Step-by-step explanation:

Answer: a. Statistic because the value is a numerical measurement describing a characteristic of a sample.

Step-by-step explanation: Statistic are numerical characteristics drawn or obtained from a sample which is a subset of a population. Numerical values obtained from a population of data is called parameter. Hence, since the set of professors from which the value of those who own a television being 40% was drawn is stated as being a sample. Then all numerical characteristics obtained from the dataset will be referred to as a statistic.

Answer:

  E.  36.8 ft

  F.  59 ft

  G.  3.5 ft or 114.5 ft

Step-by-step explanation:

E. Put x=60 in the equation and do the arithmetic.

  h = -0.01·60^2 +1.18·60 +2 = -36 +70.8 +2 = 36.8

The height is 36.8 feet when the ball is 60 feet downfield.

__

F. The vertex of expression ax^2 +bx +c is x = -b/(2a). Here, that is ...

  x = -(1.18)/(2(-0.01)) = 59

The ball has traveled 59 feet downfield when it reaches its maximum height.

__

G. To find the downfield distance for a height of 6 feet, we set h=6 and solve for x.

  6 = -0.01x^2 +1.18x +2

  0.01x^2 -1.18x +4 = 0 . . . put in standard form

  x^2 -118x +400 = 0 . . . . . multiply by 100 to get rid of decimals

  x = (118 ± √(118² -4(1)(400)))/(2) = 59 ±√3081

  x ≈ 59 ± 55.5 ft = {3.5 ft, 114.5 ft}

The ball will be 6 ft high at distances of 3.5 and 114.5 ft downfield.

Answer:

Neither

Step-by-step explanation:

Parallel lines have the same gradient while the product of the gradients of perpendicular lines is -1.

Let's find the gradient of each line first.

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

[tex]gradient \: of \: first \: line \\ = \frac{1 - ( - 2)}{3 - ( - 2)} \\ = \frac{1 + 2}{3 + 2} \\ = \frac{3}{5} [/tex]

[tex]gradient \: of \: the \: other \: line \\ = \frac{5 - ( - 6)}{5 - 4} \\ = \frac{5 + 6}{1} \\ = 11[/tex]

Product of the gradients

= 11 ×⅗

= 6.6

Since the gradients are neither the same, nor do the product of the gradients equal to -1, the 2 lines are neither parallel or perpendicular to each other.

Answer:

6 units

Step-by-step explanation:

because since AC is 24 units long, and BC is half of AC, then that would be 12 units, and since DC is half of BC, then that would be six units.

Step-by-step explanation:

2 x 2 + x - 4 = 0

4 + x - 4 = 0

+4 +4

8 0

8 + x = 0

8 8

x = 0

For the - 4 + 4 part, it cancels out because it's 0 and for the 8 divided by 8 part, it cancels out too. x is 0 because 0 divided by 8 is 0.

Answer:

C. y>2x+1

Step-by-step explanation:

The dashed line automatically means it's either A. or C. because a dashed line indicates it is greater than or less than rather than greater than/ equal to or less than/equal to. Those would have a solid line graphed. The line also has a y-intercept or 1 which means C. is obviously the correct answer.

Answer:

x=-28

Step-by-step explanation:

Step 1: Cross-multiply.

x+4

−6

=

8

2

(x+4)*(2)=(8)*(−6)

2x+8=−48

Step 2: Subtract 8 from both sides.

2x+8−8=−48−8

2x=−56

Step 3: Divide both sides by 2.

2x

2

=

−56

2

x=−28

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

Work Shown:

(x+4)/(-6) = 8/3

3(x+4) = -6*8 ... cross multiply

3x+12 = -48

3x = -48-12 ... subtract 12 from both sides

3x = -60

x = -60/3 ... divide both sides by 3

x = -20

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

Check:

(x+4)/(-6) = 8/3

(-20+4)/(-6) = 8/3 .... replace every x with -20

(-16)/(-6) = 8/3

(-2*8)/(-2*3) = 8/3

8/3 = 8/3 ... the '2's cancel when dividing

We get the same number on both sides, so this confirms the solution.

Answer:

2.25 feet

Step-by-step explanation:

The length of the remaining piece of board will be 2 feet 3 inches.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

It is given that Donny had a 10-foot board. He used the board to make two shelves. One shelf measured 4 feet 7 inches wide and the other shelf measured 3 feet 2 inches wide.

The length of the remaining part is calculated as below:-

10 foot = 10 x 12 = 120 inches

4 feet 7 inches = (4 x 12) + 7 = 48 + 7 = 55 inches

3 feet 2 inches = ( 3 x 12 ) +2 = 36 + 2 = 38 inches

Remaining length = 120 - 55 - 38 = 27 inches

                             = 24 + 3 = 2 feet 3 inches.

Therefore, the length of the remaining piece of board will be 2 feet 3 inches.

Answer:

Bill is 25 years old and Jenny is 29 years old

Step-by-step explanation:

Systems of Equations:

J = 4 + B

J + B = 54

Substitute J into the first equation.

4 + B + B = 54

Add like terms.

4 + 2B = 54

Isolate the variable.

4 + 2B = 54

-4            -4

2B = 50

2B/2 = 50/2

B = 25 years old

Plug in B into the second equation of the system.

J + B = 54

J + 25 = 54

Isolate the variable.

J + 25 = 54

   -25   -25  

J = 29 years old

Check your answer. Pick whatever equation in the system and plug in your answers.

J = 4 + B

29 = 4 + 25

29 = 29

Answer: The numerator simplified is equal to 2^9. This is because you add the exponents to simplify. The denominator is also equal to 2^9 because you multiply the exponents to simplify. 2^9 divided by 2^9 equals 1.

Step-by-step explanation:

Answer:

It is equal to 1 because: 2^4 is 16, 2^5 is 32, 16 times 32 is 512. 2^3 is 8, 8^3 is 512. 512/512 is 1.

Answer:

5 and 24

Step-by-step explanation:

1) replace the x's with 125 | c(x)=120+4(125)/(125)

620/125=5 simplify numerator

x=5

2) replace c(x) with 9 | 9=120+4x/x

9x=4x+120 multiply both sides by x

9x-4x=4x+120-4x subtract both sides by -4x

5x=120 divide both sides by 5

x=24

so, it costs about 5 dollars per book when 125 are printed

and, if it costs 9 dollars per book, 24 should be printed

The given function for the cost of printing is a linear function that has a

fixed (set up) cost and a variable cost component.

The correct responses are;

Reasons:

Given that the function for the cost of printing x books is; c(x) = 120 + 4·x, we have;

1. The cost of printing 125 books is c(125) = 120 + 4 × 125 = 620

2. The amount the author plans to charge per book = $9

The number of books, n, that should be printed is given as follows;

[tex]\displaystyle 9 = \mathbf{ \frac{120 + 4 \times n}{n}}[/tex]

Which gives;

9·n = 120 + 4·n

9·n - 4·n = 120

5·n = 120

[tex]\displaystyle n = \frac{120}{5} = \mathbf{24}[/tex]

The number of books that should be printed, n ≥ 24 books
