The number of papers checked by both becomes equal in 10 hours.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Teacher Malone is reviewing papers in the educators' parlor. She has previously gotten done with reviewing 20 tasks and is evaluating 5 additional tasks each hour. Her showing colleague just came in to help her. He can grade at a pace of 7 tasks consistently.

Let 'x' be the number of hours and 'y' be the number of assignments. Then the equations are given as,

y = 5x + 20        ...1

y = 7x                ...2

At some point, they will be finished and will have graded the same number of papers. Then from equations 1 and 2, we have

7x = 5x + 20

7x - 5x = 20

2x = 20

x = 20 / 2

x = 10

The number of papers checked by both becomes equal in 10 hours.

Answer:

7 1/12 bushels of sweet corn per acre of land

Step-by-step explanation:

Total bushels of sweet corn harvested this year fewer than the previous year = 21 1/4

Total acres of land used to plant = 3 acres

what is the average loss per acre?

Average loss = Total bushels of sweet corn harvested for the year / 3 acres

= 21 1/4 ÷ 3

= 85/4 ÷ 3

= 85/4 × 1/3

= 85 / 12

= 7 1/12

Average loss = 7 1/2 bushels of sweet corn per acre of land

Answer:

165

Step-by-step explanation:

We solve the first 5

1*(10-1)=9

2*(10-2)=16

3*(10-3)=21

4*(10-4)=24

5*(10-5)= 25

and notice

when you go from 6 on its getting the same number because say 3*(10-3) = 3*7 and 7*(10-7) = 7*3 and 7*3 = 3*7 so

You add the first 5 integer you solved up

9 16 21 24 25 = 95

and then you double it no extra 25

and then you get 165 = answer

Answer:

[tex]x=\frac{-1}{4} +/-\frac{1}{4}\sqrt{17}[/tex]

Step-by-step explanation:

First, we need to get the equation into the polynomial form. Add 8 to both sides:

[tex]-6x^{2} -2-3x=-8[/tex]

[tex]-6x^{2} +6-3x=0[/tex]

Rearrange the equation so that it is in standard form:

[tex]-6x^{2} -3x+6=0[/tex]

Remember the quadratic formula:

[tex]\frac{-b+/-\sqrt{b^{2}-4ac} }{2a}[/tex]

[tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are the coefficients of the problem when it is in standard form. In this case, [tex]a=-6[/tex], [tex]b=-3[/tex], and [tex]c=6[/tex]. Now, all we need to do is plug those into the quadratic formula.

[tex]\frac{-(-3)+/-\sqrt{(-3)^{2}-4(-6)(6)} }{2(-6)}[/tex]

Simplify:

[tex]\frac{3+/-\sqrt{153}}{-12}[/tex]

[tex]x=\frac{-1}{4} +/-\frac{1}{4}\sqrt{17}[/tex]

Answer:

Please read the explanied answer below.

Step-by-step explanation:

We also know that a regular polygon has all the angles equal and all sides have the same length.

As we know:

When the number of sides changes, the angle also changes. Therefore, we would get different integers as answer.

For example:

In terms of a triangle:

Exterior angle = 360° ÷ No. of sides

                        = 360° ÷ 3 = 120°

In terms of a rectangle:

Exterior angle = 360° ÷ No. of sides

                        = 360° ÷ 4 = 90°

and in the same way

360° ÷ 5 = 72 °

360° ÷ 6 = 60 °

360° ÷ 8 = 45 °

360° ÷ 9 = 40°

and so on.

I hope it may have solved your query.

Answer:

255 caps were sold

Step-by-step explanation:

25x+10y = 9000

25(258) + 10y = 9000

6450 + 10y = 9000

-6450 + 10y = -6450

10y = 2550

2550/10y

I believe the answer would be C (sorry i messed uo the first time)

Answer:

C

Step-by-step explanation:

Answer:

c=37

Step-by-step explanation:

The answer c is 37.

Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number

Here is is given that,

629 divided by the number c equals 17.

Here 629 is the dividend, c is the divisor and 17 is the quotient.

We have to find the value of the divisor.

Mathematically the given statement can be written as,

629 / c = 17

Multiplying both sides of the equation with c, we get,

629 = 17 c

Dividing both sides by 17,

c = 629 / 17

c = 37

Hence the value of c is 37.

The graph that shows a polynomial function with an even degree is option D.

A function is a law that relates two variables, a dependent and an independent variable with each other.

The domain and range of a function is always defined, the domain is all the values that can be an input to the function and the range is all the valuess that a function can have.

A function that involves positive integer powers as exponents of a variable in an equation is called a polynomial function, like the quadratic equation,

An even degree polynomial function, represented by y = x², have graphs that either open upwards or downwards.

A function is even if, for each x in the domain of f, f (- x) = f (x).

In an even function, the graph is symetrically along y axis.

The only graph that is symmetrical along the y axis is graph D.

Answer:

Sue gets the largest share of 15, which is the smallest possible number of sweets Sue could get.

Step-by-step explanation:

Basil, Oscar, and Sue share 43 sweets.

Sue gets the largest share.

Let us divide the 42 sweets by 3

42/3 = 14

It means 3 equal parts of 14 make the sum 4.

i.e. 14+14+14 = 42

Since Basil, Oscar and Sue share 43 sweets, which is 1 plus 42.

So, add that 1 to Sue. i.e. 1+14 = 15

Thus, Sue gets the largest share of 15, which is the smallest possible number of sweets Sue could get.

Answer:

$3.20

Step-by-step explanation:

We have

15-mile stretch = $0.60

80-mile stretch = x

Cross Multiply

x = 80 × $0.60/15

x = $3.20

Hence, the cost to drive a 80-mile stretch is $3.20

Step-by-step explanation:

Answer:

W=18ft

L=24ft

Step-by-step explanation:

Step one:

given data

area= 425ft^2

let the width W be =x

and the length L be =x+6

Required

Length and width

solution

Area= lenth*width

432=x*(x+6)

432=x^2+6x

x^2+6x-432=0

The roots of the quadratic equation is

x=-24-----can not be negative

x=18----correct

The dimension is

the width W =x=18ft

The length= x+6=18+6=24ft

check area= 18*24=432ft^2

Answer:y – 9. 4 less than a number. y - 4

Step-by-step explanation:

If the sum of a number and 9, divided by 4, is greater than or equal to -2, the number is -17.

A collection of two or more inequalities in one or more variables is known as a system of inequalities. When there are multiple constraints on a problem's potential solutions and a range of potential solutions are needed, systems of inequalities are used. The maximum or minimum values of a situation with multiple constraints are frequently determined using a system of linear inequalities.

It is given that,the sum of a number and 9, divided by 4, is greater than or equal to -2

Suppose the number is n,

(n+9)/4≥-2

n+9≥-8

n≥-8-9

n≥-17

Thus, if the sum of a number and 9, divided by 4, is greater than or equal to -2, the number is -17.
