Answer:

The answer is 7n3 + 6.

Step-by-step explanation:

To simplify, remove the parentheses and combine like terms.

The standard form of the given expression is 7n³+6.

The given expression is (4+2n³)+(5n³+2).

To add any two expressions group the like terms.

Here, 4+2n³+5n³+2

= (2n³+5n³)+4+2

= 7n³+6

Therefore, the standard form of the given expression is 7n³+6.

Answer:

x = -(a - b)/b

Step-by-step explanation:

Solve for x:

a = b (1 - x)

a = b (1 - x) is equivalent to b (1 - x) = a:

b (1 - x) = a

Divide both sides by b:

1 - x = a/b

Subtract 1 from both sides:

-x = (a - b)/b

Multiply both sides by -1:

Answer: x = -(a - b)/b

Step-by-step explanation:

Answer:

16.485 feet

Step-by-step explanation:

Given that tire is 5.25 feet tall

any circular shape is as tall as its diameter.

we can say that diameter of tire is 5.25 feet.

in one rotation tire will start from one point of tire and reach it again.

it is like on a circle moving from on one point and then reaching to same point.

and we know that distance covered on moving on the point of circle is equal to circumference.

Thus, measure of circumference would help to find how many feet the tractor will travel in 1 rotation.

circumference of circle is given by [tex]\pi D[/tex]

where D is the diameter of circle.

we will us 3.14 as value of [tex]\pi[/tex]

thus, circumference of circle is[tex]\pi * 5.25 = 3.14*5.25 = 16.485[/tex]

Hence, tractor would travel 16.485 feet in one rotation.

Answer:

N/2 + 7 = 2N - 5

N + 14 = 4N - 10

24 = 3N

N = 8

Answer:

1/2n + 7 = 2n - 5

2 · 1/2n + 7 · 2 = 2n · 2 - 5 · 2

n + 14 = 4n - 10

n - n + 14 = 4n - n - 10

14 = 3n - 10

14 + 10 = 3n - 10 + 10

24 = 3n

Can you please tell me what is the area of the given triangle?

Answer:

141

Step-by-step explanation:

We need to first find the volume of the cannonballs and then, divide the volume of the closet by the volume of the cannonballs.

The radius of the spherical cannonball is 0.75 feet.

The volume of a sphere is:

[tex]V = \frac{4}{3} \pi r^3[/tex]

where r = radius

Therefore, the volume of the cannonballs is:

[tex]V = \frac{4}{3} * \pi * 0.75^3\\\\V = 1.77 ft^3[/tex]

Therefore, the number of cannonballs that can fit the closet is:

250 / 1.77 = 141.24

Since the number is a maximum and it must be a whole number, the number of cannonballs that can fit the closet is 141.

Answer:

x = 8.5

Step-by-step explanation:

In this question, we are to calculate the value of x.

To calculate this, we shall be utilizing one of the important properties of parallelogram.

This property is that opposite angles of a parallelogram are equal.

This means that mQSR = mSPQ = 4x + 90

Now to finally calculate x, we make use of another important parallelogram property which is that angles of parallelogram which faces each other are supplementary.

This means that they add up to be 180

Since mQSR faces mQRS

This means that;

4x + 90 + 9x -20 = 180

13x + 70 = 180

13x = 110

x = 110/13 which is approximately 8.5

Complete Question:

The scatter plot shows the number of oranges picked, in hundreds, in relation to the number of lemons harvested, in hundreds, by several farmers. According to the plot, which value is the best estimate of the correlation coefficient of the data?

A.-0.2

B. -0.9

C. 0.9

D. 0.2

*See attachment for the scatter plot

Answer:

C. 0.9

Step-by-step explanation:

If we take a good look at the scatter plot in the attachment showing numbers if oranges picked in relation to number of lemons harvested, we can infer that there's a strong positive correlation between both variables.

Thus, both variables are moving in the same direction. As one variable increases, the other variable increases. Also, the data points represented on the plot seem clustered close to the line rather than farther away.

This will suggest a positive correlation coefficient that is closer to 1.

From the options given above, the best estimate of the correlation coefficient would be 0.9.

The answer is C. 0.9

Answer:

(5s + 8) is the missing factor.

Step-by-step explanation:

The given expression is 5s² + 23s + 24

We have to convert the given expression into the factored form.

One factor of the expression has been given as (x + 3)

5s² + 23s + 24 = 5s²+ 15s + 8s + 24

                        = 5s(s + 3) + 8(s + 3)

                        = (5s + 8)(s + 3)

So the factors of the expression will be (s + 3) and (5s + 8)

Therefore, the missing factor of the given expression is (5s + 8).

  8.  ∠CBD = ∠BCE = 100°; ∠CED = ∠BDE = 80°

Step-by-step explanation:

7. We presume the angles at A are congruent, so that each is 180°/9 = 20°.

Then the congruent base angles of isosceles triangle ABC will be ...

  ∠B = ∠C = (180° -20°)/2 = 80°

The angle of interest, ∠CBD is the supplement of ∠ABC, so is ...

  ∠CBD = 180° -80°

  ∠CBD = 100°

  ∠CED = ∠BDE = 80°

Answer:

$10579.49

Step-by-step explanation:

The formula for amount gotten after a period of time (in years) on a principal which is compounded continuously is given as:

[tex]A = P(1 + r)^t[/tex]

where P = principal (amount borrowed)

r = interest rate

t = number of years

Peter accumulated $7,500 in credit card debt with interest rate as 3.5% per year and he does not make any payments for 10 years.

Therefore, his debt is:

[tex]A = 7500(1 + \frac{3.5}{100})^{10}\\ \\A = 7500 (1 + 0.035)^{10}\\\\A = 7500(1.035)^{10}\\[/tex]

A = $10579.49

He will owe $10579.49 after 10 years

Answer:

A= $10,643.01

Step-by-step explanation:

if you are rounded to the nearest cent

Identify the values of each variable in the formula. Remember to express the percent as a decimal.

A=?

P= $7,500

r= 0.035

t= 10 years

For compounding continuously, use the formula A=Pert.

Substitute the values in the formula and compute the amount to find

Answer:

x° = ∠OBR = ∠ABC (base angles of a cyclic isosceles trapezoid)

Step-by-step explanation:

APRB form a cyclic trapezoid

∠APO  = x° (Base angle of an isosceles triangle)

∠OPR  = ∠ORP (Base angle of an isosceles triangle)

∠ORB = ∠OBR (Base angle of an isosceles triangle)

∠APO + ∠OPR + ∠OBR = 180° (Sum of opposite angles in a cyclic quadrilateral)

Similarly;

∠ORB + ∠ORP + x°  = 180°

Since ∠APO = x° ∠ORB = ∠OBR and ∠OPR  = ∠ORP we put

We also have;

∠OPR = ∠AOP = ∠BOR (Alternate interior angles of parallel lines)

Hence 2·x° + ∠AOP = 180° (Sum of angles in a triangle) = 2·∠OBR + ∠BOR

Therefore, 2·x° = 2·∠OBR, x° = ∠OBR = ∠ABC.

Answer:on the circle

Step-by-step explanation:

Point J(-3, 12) is lying on the circle whose center is located at point D(-1, 3).

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have a center of the circle at D(-1, 3)

And point G(-10, 1) is on the circle.

We know the standard equation of the circle when a center is given:

[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]

Where r is the radius of the circle and (h, k) is the center of the circle.

Here (h, k) ⇒ (-1, 3)

The circle equation becomes:

[tex]\rm (x+1)^2+(y-3)^2=r^2[/tex]

Put the point on the circle equation to get the radius of the circle:

[tex]\rm (-10+1)^2+(1-3)^2=r^2[/tex]

[tex]\rm (-9)^2+(-2)^2= r^2\\\\\rm 81+4 = r^2\\\\ \rm r = \sqrt{85} \ units[/tex]

Equation of circle is:

[tex]\rm (x+1)^2+(y-3)^2=85[/tex]

Now put the point J(-3, 12 ) in the circle equation:

[tex]\rm (-3+1)^2+(12-3)^2=85[/tex]

4+ 81 ⇒ 85

It means point J is lying on the circle.

Thus, point J(-3, 12) is lying on the circle whose center is located at point D(-1, 3).

Step-by-step explanation:

The recipe makes 6 portions and you need 18 portions. Since 6 is 3 times smaller than what you need, just times everything you've been given by 3.

*you can choose to convert into the correct units of measurement before or after dividing. I converted after dividing. Either way works fine though.

1) 60 x 3 = 180 ml

2) 80 x 3 = 240 g

3) 450 x 3 = 1350 g

They want it in kilograms, so divide it by 1,000 to convert. this gives you 1.35 kg.

4) 600 x 3 = 1800 ml

They want it in l, so divide it by 1,000 to convert. this gives you 1.8 l.
