If the area of a rectangle is 12mn^2 and the width is 3m^2n, what would be the length of the rectangle, given that length is found by dividing area by length?

Answers

Answer 1

Let's see

Area=Length×Breadth

[tex]\\ \rm\rightarrowtail 3m^2n(L)=12mn^2[/tex]

[tex]\\ \rm\rightarrowtail mL=4n[/tex]

[tex]\\ \rm\rightarrowtail L=4n/m[/tex]

Answer 2

Answer:

[tex]\sf length=\dfrac{4n}{m}[/tex]

Step-by-step explanation:

Area of a rectangle = width × length

Given:

[tex]\sf area=12mn^2[/tex][tex]\sf width=3m^2n[/tex]

Substituting the given expressions into the equation:

[tex]\sf \implies 12mn^2=3m^2n \times length[/tex]

[tex]\sf \implies length=\dfrac{12mn^2}{3m^2n}[/tex]

Factor 12 to 3 · 4:

[tex]\sf \implies length=\dfrac{3 \cdot 4mn^2}{3m^2n}[/tex]

Cancel the common factor of 3:

[tex]\sf \implies length=\dfrac{4mn^2}{m^2n}[/tex]

Simplify [tex]\sf \dfrac{n^2}{n}=n[/tex] :

[tex]\sf \implies length=\dfrac{4mn}{m^2}[/tex]

Simplify [tex]\sf \dfrac{m}{m^2}=\dfrac{1}{m}[/tex] :

[tex]\sf \implies length=\dfrac{4n}{m}[/tex]

We must order these decimals from least to greatest. Then we must determine how the least compares with the winning score.

9.80 -> 3

9.75 -> 1

9.79 -> 2

9.81 -> 4

The least decimal is 9.75. Now we must determine how 9.75 compare with the winning score.

Answers

Answer:

Disagree because the slopes are different.

Step-by-step explanation:

When an equation is in y=mx+b form, answering these kinds of questions becomes easier. "M" is your slope, so if m for both equations match, then your lines will be parallel. This one shows the first equation as 2/1, so you would rise 2 and run 1. but the second is 2.5 or 5/2, so you would rise 5 and run 2. rise meaning y-axis and run being the x-axis. Whenever possible, I turn equations to the y=mx+b form because it makes everything a bit clearer, in my opinion.

The sum of the squares of two consecutive integers is 145. Find the two integers.
Please help asap .

Answers

Answer: The two integers are 8 and 9.

Step-by-step explanation: Let n represent the number.

n^2 + (n + 1)^2 = 145

By foiling, this can be rearranged to:

n^2 + n^2 + 2n + 1 = 145

Subtract 145 from both sides:

2n^2 + 2n - 144 = 0

Divide both sides by 2:

n^2 + n - 72 = 0

Factor the polynomial:

(n + 9)(n - 8) = 0

Solve for n:

n = -9, n = 8

Since they need to be consecutive, make the 9 positive. It will be positive either way because it is being squared.

Now, n = 9 and n = 8.

These are your two integers. Hope this helps!

a. how much will he have paid total?
b. how much more did he pay than the price of the car?

Answers

Using compound interest, it is found that:

a) He will have paid $18,774 in total.

b) He paid $4,774 more than the price of the car.

What is compound interest?

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.

In this problem, the parameters are:

[tex]P = 14000, r = 0.049, n = 12, t = \frac{72}{12} = 6[/tex].

Item a:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]A(6) = 14000\left(1 + \frac{0.049}{12}\right)^{12 \times 6}[/tex]

[tex]A(6) = 18774[/tex]

He will have paid $18,774 in total.

Item b:

18774 - 14000 = $4,774.

He paid $4,774 more than the price of the car.

Work out the area of the triangle. Give your answer to 1 decimal place. 10cm, 13cm sides. Angle 105

Answers

Answer:

62.8

Step-by-step explanation:

So, keep in mind that the area of a triangle is equivalent to: 1/2(b)(h) with b being your base and h being your height.

We have our base: 10, and our angle: 105. Now we need to find our height. You don't just have to look at a triangle the way that it's oriented in the problem. Rotate it so that 10cm is at the bottom, and it will be much easier.

From there, you can create a right triangle and draw a line from the top of the triangle straight to the base. Then, you have a right triangle, where you can solve the height, and then plug your answer into the area formula. Further steps are detailed in the picture.

What is Pythagoras Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

The simplified figure is attached below.

We need to find the area PQRS.

Area(PQRS) = 4(Area(DOQ) + Area(QOB)) (by symmetry.

The line OD and OT are perpendiculars on those 38 inch chords, and therefore D and T are bisecting them(by a theorem that perpendicular from center of a circle to its chords bisect them).

Finding Area of DOQ:

Using Pythagoras theorem, we get:
[tex]|DO| = \sqrt{|OQ|^2 -|DQ|^2 } = \sqrt{22^2 - 19^2} = \sqrt{123}[/tex]

Thus, we get:

[tex]\text{Area DOQ} = \dfrac{1}{2} \times 19 \times \sqrt{123} \approx 105.36 \: \rm in^2[/tex]

Finding Area of QOB:

Since angle ∠DQO and ∠QOB are alternate interior angle, they are of same measure.

From triangle DOQ, from the perspective of ∠DQO, we get the sine ration as:

[tex]\sin(m\angle DQO) = \dfrac{|DO|}{|OQ|}\\m\angle DOQ = \sin^{-1}\left( \dfrac{\sqrt{123}}{22}\right) \approx 30.27^\circ \: \text{(chose acute angle)}[/tex]

Thus, we get:
[tex]m\angle QOB \approx 30.27^\circ[/tex]

360 degrees cover full area of circle,

1 degree will cover full area /360 of the circle

Thus, we get:

Aera of the sector QOB = Area covered by central angle ∠QOB[tex]\approx 30.27 \times \dfrac{\pi (22)^2}{360} \approx 127.85 \: \rm in^2[/tex]

Thus, as we have:

Area(PQRS) = 4(Area(DOQ) + Area(QOB))

we get:

Area(PQRS) ≈ 4(105.36 + 127.85) ≈ 932.84 in.²

Thus, the area of the center section when the leaves are down is evaluated being of 932.84 in.²

True, the three sides will form exactly one unique triangle.

What is a triangle?

A triangle is three dimensional shape, whose third length is less than the sum of the first and second length.

let the first length = alet the second length = blet the third length = k

(b - a) < k < (b + a)

(6.3 - 5.2 ) < k (6.3  + 5.2 )
