Answer:

x = 3.25 Each diagonal = 34.25. Step-by-step explanation: LMNP is a rectangle and it has diagonals LN and MP. Now, given that LN = 13x - 8 and MP = 9x + 5 Now, we know that the two diagonals of a rectangle are of the same length. So, LN = MP   ⇒ 13x - 8 = 9x + 5 ⇒ 4x = 13 ⇒ x = 3.25 (Answer) Therefore, the each diagonal is of (13 × 3.25 - 8) = 35.25 length. (Answer)

Answer:

basketballs = 210 footballs = 70

Step-by-step explanation:

footballs =b

basketballs= 3b

if there ate 140 fewer footballs than basketballs it means that the difference between basketballs and footballs sold is 140

hence 3b - b = 140

2b= 140

b= 70

hence footballs are 70

while basketballs are 70×3 = 210

The volume of the three-dimensional figure is 3.75 yd³, and it can hold 7500 pounds of soil

Volume is the amount of space occupied by a three dimensional shape or object.

The volume of the three dimensional shape is:

Volume = length * width * height = 1 1/4 * 1 1/2 * 2 = 3.75 yd³

1 yd³ = 2000 pounds

3.75 yd³ = 2000 pounds * 3.75 yd³ = 7500 pounds

The volume of the three-dimensional figure is 3.75 yd³, and it can hold 7500 pounds of soil

In Cartesian coordinates, the volume is

[tex]\displaystyle \iiint_R \mathrm dV[/tex]

where R is the set

[tex]R = \left\{(x,y,z) \, : \, -4\le x\le4 \text{ and } -\sqrt{16-x^2} \le y \le \sqrt{16-x^2} \text{ and }\right. \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~\left.-\sqrt{16-x^2-y^2} \le z \le \sqrt{16-x^2-y^2} \right\}[/tex]

Converting to spherical coordinates, we take

[tex]\begin{cases}x=\rho\cos(\theta)\sin(\phi) \\ y=\rho\sin(\theta)\sin(\phi) \\ z = \rho\cos(\phi)\end{cases}[/tex]

and we can compute the Jacobian to find

[tex]dV = dx\,dy\,dz = \rho^2 \sin(\phi) \, d\rho \, d\theta \, d\phi[/tex]

and the set R transforms to

[tex]R' = \left\{(\rho,\theta,\phi) \,:\, 0\le \rho\le4 \text{ and }0\le\theta\le2\pi \text{ and } 0\le\phi\le\pi\right\}[/tex]

The new integral and hence the volume is then

[tex]\displaystyle \iiint_R \mathrm dV = \iiint_{R'} \rho^2 \sin(\phi) \, d\rho \, d\theta \, d\phi \\\\ = \boxed{\int_0^\pi \int_0^{2\pi} \int_0^4 \rho^2 \sin(\phi) \, d\rho \, d\theta \, d\phi}[/tex]

Step-by-step explanation:

1.

so 90 km on 17 liters.

that is a 90/17 ratio (or proportion).

that means it runs 90/17 km on 1 liter.

and therefore (90/17)×20 on 20 liters.

90×20/17 = 105.8823529... km

2.

the ratio is 66/22 based on the RPMs.

66/22 = 3/1 = 3

so, the larger gear has then 3×6 = 18 teeth.

3.

the ratio is 150/75 based on the RPMs.

the circumference of a circle is

2×pi×r

so, it is a linear relationship with the radius r (and therefore the diameter d).

so, the diameter of the larger pulley is 2×10 = 20 in

4.

the ratio here is 18/6.

18/6 = 3/1 = 3.

again, this relates to the circumference, which is a linear relationship with the radius or diameter.

the smaller gear has then 72/3 = 24 teeth.

5.

the ratio is 2/3.

so, the larger pulley has 3450×2/3 RPM.

= 2,300 RPM

6.

2.5 kg cost 110.

that is a 2.5/110 ratio :

and that means we get 2.5/110 kg for one unit of money.

and therefore we get 80 × 2.5/110 kg for 80 units of money.

80 × 2.5/110 = 8 × 2.5/11 = 20/11 = 1.818181818... kg

I assume the base of S is the disk centered at the origin, or x² + y² ≤ r². Solving for y gives two solutions corresponding to the upper and lower halves of the circular boundary,

[tex]x^2+y^2 = r^2 \implies y = \pm \sqrt{r^2-x^2}[/tex]

and the vertical distance between them - i.e. the side length of each cross section - is

[tex]\sqrt{r^2-x^2} - \left(-\sqrt{r^2-x^2}\right) = 2\sqrt{r^2-x^2}[/tex]

Then the volume of each square cross section 4 (r² - x²) ∆x, and the volume of S is

[tex]\displaystyle \int_{-r}^r 4(r^2-x^2) \, dx[/tex]

By symmetry, this is the same as

[tex]\displaystyle 8 \int_0^r (r^2-x^2) \, dx[/tex]

which gives a volume of

[tex]\displaystyle 8 \int_0^r (r^2-x^2) \, dx = 8 \left(r^3 - \frac{r^3}3\right) = \boxed{\frac{16r^3}3}[/tex]

It can be inferred that H0: ? = 15, Ha: ? = 15 doesn't comply because both hypothesis use an equal sign.

From the information, H0: p = 0.5, Ha: p > 0.6 doesn't comply because the two hypothesis use different numbers.

Furthermore, H0: ? = 121, Ha: ? < 121 shows that the pair complies. Also, H0: ? = 123, Ha: ? = 125 doesn't comply as they use the equal sign and different numbers.

Lastly, H0: p? = 0.2, Ha: p? ? 0.2 doesn't comply because p is not a population characteristic.

The distance of AB is 42.04 units, BC is 35.77 units and CA is 34.5 units.

We have,

The length along a line or line segment between two points on the line or line segment.

The coordinates of A are (-18, -18)

coordinates of B are (20, 0)

coordinates of C are (-12, 16)

The formula for distance is Distance=√(x₂-x₁)²+(y₂-y₁)²

Distance AB=√(20-(-18))²+(0-18)²

=√(20+18))²+(0-18)²=√38²+18²

AB=√1444+324

    =√1768

    =42.04 units

Distance BC=√(-12-20)²+(16)²

=√(-32)²+(16)²=√1024+256

=√1280

=35.77

Distance CA=√(-12-(-18))²+(16+18)²

=√(6)²+(34)²

=√36+1156=34.5

Hence, the distance of AB is 42.04 units, BC is 35.77 units and CA is 34.5 units.

Answer:

1 Shirt and 185cm remaining cloth

Step-by-step explanation:

2m and 15cm = 215cm

40m = 400cm

400/215=1.860465116

A shirt cant be in decimal so we remove the decimals, and take the as the answer. For the decimals, they are the remaining cloth.. to calculate the amount of remaining cloth we do:

1.860465116-1

=860465116

215*860465116=185cm

Answer:

A. 5/1

C. -0.02

D. 4.177777....

Step-by-step explanation:

Rational numbers can be written as a ratio of numbers, such as 5/1. As decimals, the numbers either

*** "terminate" the decimal has a certain number of digits and then stops, such -0.02, this can be written as a ratio -2/100 which is -1/50

OR

*** "repeats" , such as 4.17777... which can also be written as a ratio, 4.1777... = 188/45

7/0 is undefined and the pi numbers are irrational, the digits of the decimal do not repeat and do not ever end, therefore NOT rational.

Combine the terms:

6+6k+k

6+7k

Rearange terms:

6+7k

7k+6

Answer:

Step-by-step explanation:

2x + 3y = -7

7x + 9y = -14

-3(2x+3y= -7) = -6x - 9y = 21

-6x - 9y = 21

7x + 9y = -14

add columns (y values cancel)

1x + 0y = 7

x = 7

plug 7 into the x value in either equation to find y

2(7) + 3y = -7

14 + 3y = -7

3y = -21

y = -7

(x,y) = (7,-7)

The notation A = {0,1, 2} is an illustration of sets

The set A do not have isolated points

An isolated point is an element of a set that belongs to a set A and any neighboring sets N, such that the set N do not contain other elements of set A

The set A is given as:

A = {0,1, 2}

The elements of the set A do not exists in other sets

So, we can say that set A do not have isolated points

Answer:

it would range between 11.28379... to 13.819765...

Step-by-step explanation:

the circle's area formula is pi * radius^2

so you make to equation, plugging the 100 and 150 into the circle's area

you get square root of (100/pi) which gets 11.28379... for the area of 100

you do the same with 150 to get square root of (150/pi) which gets 13.819765...

those are the diameter of the circle since the diameter is double the radius which i already multiplied afterwards. so if you need the radius divide the number ive given you

Step-by-step explanation:

Presumably you mean the second derivative of y with respect to x, d²y/dx².

Compute the first derivative. By the chain rule,

[tex]\dfrac{dy}{dx} = \dfrac{dy}{dt} \times \dfrac{dt}{dx} = \dfrac{\frac{dy}{dt}}{\frac{dx}{dt}}[/tex]

Differentiate the two parametric equations with respect to t :

[tex]x = \sin(t) \implies \dfrac{dx}{dt} = \cos(t)[/tex]

[tex]y = \cos(t) \implies \dfrac{dy}{dt} = -\sin(t)[/tex]

Then the first derivative is

[tex]\dfrac{dy}{dx} = \dfrac{-\sin(t)}{\cos(t)} = -\tan(t)[/tex]

Now, dy/dx is a function of t, so we can denote it by, say, dy/dx = f(t). Then by the chain rule, the second derivative will be

[tex]\dfrac{d^2y}{dx^2} = \dfrac{df}{dx} = \dfrac{df}{dt} \times \dfrac{dt}{dx} = \dfrac{\frac{df}{dt}}{\frac{dx}{dt}}[/tex]

Differentiating f(t) :

[tex]f(t) = -\tan(t) \implies \dfrac{df}{dt} = -\sec^2(t)[/tex]

Then the second derivative is

[tex]\dfrac{d^2y}{dx^2} = \dfrac{-\sec^2(t)}{\cos(t)} = \boxed{-\sec^3(t)}[/tex]

and since y = cos(t), we can go on to say

[tex]\dfrac{d^2y}{dx^2} = -\dfrac1{y^3}[/tex]
