Answer =2n^2+11n

you welcome:)

2n² + 11n

5(n² + n) – 3(n²2 – 2n) =

= 5n² + 5n - 3n² + 6n

= 2n² + 11n

Answer:

(3,4)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2

(2+4)/2 = 6/2 =3

To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2

(5+3/2 = 8/2 =4

The midpoint is (3,4)

Answer:

Hey there!

Using the midpoint formula we find the midpoint to be: (3, 4)

Answer:

Step-by-step explanation:

A =  1/2 bh

Let's simplify the right side.

A = (bh) / 2

Multiply both sides by 2

2A = bh

Divide both sides by b

(2A) / b = h

0.7 is a rational number.

Because it is a terminating decimal expansion.

Answer:

The decimal 0.7 is a rational number. It is read as seven tenths and is equivalent to the fraction 7/10. Since it can be written as a fraction

If you divide the circumference C over the radius r, you get 2pi

2pi = C/r

this is because

C = 2pi*r

is one formula to find the circumference. Another formula is

C = pi*d

which works because d = 2r, ie the diameter is twice the radius.

The solution is $ 9.50

The weekly per hour rate of Tasha is $ 9.50

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The weekly per hour of Tasha last week = $ 422.75

The extra overtime pay of Tasha for 3 hours = $ 42.75

The total number of hours working = 40 hours

So , the equation will be

The weekly per hour of Tasha without overtime = weekly per hour of Tasha last week - overtime pay of Tasha for 3 hours

Substituting the values in the equation , we get

The weekly per hour rate of Tasha without overtime = 422.75 - 42.75

The weekly per hour of Tasha without overtime = $ 380

So , The weekly per hour rate of Tasha A = The weekly per hour rate of Tasha without overtime / total number of hours working

Substituting the values in the equation , we get

The weekly per hour rate of Tasha A = 380 / 40

The weekly per hour rate of Tasha A = $ 9.50

Therefore , the value of A is $ 9.50

Hence , The weekly per hour rate of Tasha is $ 9.50

Answer:

40,550

Step-by-step explanation:

Given that 12 people can comfortably fit in a 5 × 5 foot square

Area of square = 5²= 25 ft²

The dimension Given by : 8 feets depth on both sides along a 2 mile section signifies a rectangular area.

Area of rectangle = (length × width)

Recall :

1 mile = 5280 feets

2 miles = 5280 × 2 = 10,560 feets

Area = 8 × 10560 = 84480 sq feets

84480 / 25 = 3379.2

Estimated number of people will be :

3379.2 × 12 = 40,550.4

Hence, estimated number of people = 40,550

The 6 at the very end is due to rounding error. In reality the 6's in 0.66666667 should go on forever. That 7 is from rounding up.

Answer:

-22 is the value of K.

Step-by-step explanation:

A simple way to see how far a mid-point or end-point is from another is by adding or subtracting. For this figure I added to see how many numbers would add twice to get from -15 to -29. -14 is the exact number from -15 to -29; divide that by 2 to get half of -14 which is -7. -7 + (-15) gives you -22.

The location of K so that JK is 1/7 of JL is -22.

Given that, K lies between J and L.

We need to find the location of K so that JK is 1/7 of JL.​

In geometry, a line segment is a part of a line that is bounded by two distinct end points and contains every point on the line that is between its endpoints.

Now, the distance between the points J and L on the number line is 14.

So, 1/7(14)=2

Answer:255.601

Step-by-step explanation:

Hi there!

~

⇒ Graph : [tex]y=6x^2+1[/tex]

∴ Rewrite the equation in vertex form.

⇒ [tex]y = 6 ( x + 0)^2 + 1[/tex]

∴ Use the vertex form, [tex]y = a(x - h)^2 + k[/tex] , to determine the values of [tex]a , h ,[/tex] and [tex]k[/tex]

[tex]a = 6 \\h = 0\\k = 1[/tex]

∴ Since the value of [tex]a[/tex] is positive, the parabola opens up.

⇵

∴ Find the vertex [tex]( h,k)[/tex].

[tex](0,1)[/tex]

∴ Find [tex]p[/tex], the distance from the vertex to the focus.

[tex]\frac{1}{24}[/tex]

∴ Find the focus.

[tex]( 0 , \frac{25}{24} )[/tex]

∴ Find the axis of symmetry by finding the line that passes through the vertex and the focus.

[tex]x = 0[/tex]

∴ Find the directrix.

[tex]y = \frac{23}{24}[/tex]

∴ Use the properties of the parabola to analyze and graph the parabola.

Direction: Opens Up

⇒ Vertex: [tex]( 0 , 1)[/tex]

⇒ Focus: [tex]( 0 , \frac{25}{24} )[/tex]

⇒ Axis of Symmetry: [tex]x = 0[/tex]

⇒ Directrix: [tex]y = \frac{23}{24}[/tex]

∴ Select a few [tex]x[/tex] values, and plug them into the equation to find the corresponding [tex]y[/tex]  values. The [tex]x[/tex] values should be selected around the vertex.

Answer:

She has 7 nickels, 11 dimes and 10 quarters

Step-by-step explanation:

Total value =$3.95

Let

Nickel = x

Dimes = x + 4

Quarters = x + 3

Every

Nickel = 5 cents

Dimes = 10 cents

Quarters = 25 cents

Total cents = $3.95 × 100

= $395

5n + 10d + 25q = 395

5(x) + 10(x+4) + 25(x+3) = 395

5x + 10x + 40 + 25x + 75 = 395

40x + 115 = 395

40x = 395 - 115

40x = 280

Divide both sides by 40

x= 280/40

= 7

x= 7

Nickel = x = 7

Dimes = x + 4

=7+4

=11

Quarters = x + 3

=7+3
