Answer:

h = 9 m

Step-by-step explanation:

[tex]V_{cone}=340\: m^3[/tex]

diameter (d) = 12 m

[tex]\implies radius\:(r)= \frac{12}{2}=6\:m[/tex]

[tex] \because \: V_{cone}= \frac{1}{3} \pi {r}^{2} h \\ \\ \implies \: h = \frac{3V_{cone}}{\pi {r}^{2} } \\ \\ \implies \: h = \frac{3(340)}{3.14 {(6)}^{2} } \\ \\ \implies \: h = \frac{1020}{113.04} \\ \\ \implies \: h = 9.02335456 \\ \\ \implies \: h \approx 9 \: m[/tex]

Answer:

Maggie = 15 hours

Ryan = 30 hours

Step-by-step explanation:

let x - time it takes Ryan to do the job alone.

x-15 - time it takes Maggie to do the job alone

[tex] \frac{10}{x} + \frac{10}{x - 15} = 1 \\ \\ \frac{10(x - 5) + 10x}{x(x - 15)} = 1[/tex]

[tex]10x - 150 + 10x = x {}^{2} - 15x \\ \\ 20x - 150 = x {}^{2} - 15x \\ \\ x {}^{2} - 15x - 20x + 150 = 0 \\ \\ x {}^{2} - 35x + 150 = 0 \\ \\ (x - 30)(x - 5) = 0 \\ \\ x = 30 \: and \: x - 15 = 15[/tex]

x = 5 --> not valid because x-15 will be NEGATIVE

Therfore,

Maggie can do the job in 15 hours.

Ryan can do the job in 30 hours.

Given for the cone:

given for the spheres:

Find volume of cone:

[tex]\sf \hookrightarrow \dfrac{1}{3} \pi r^2h[/tex]

[tex]\sf \hookrightarrow \dfrac{1}{3} \pi (3a)^2(4a)[/tex]

[tex]\sf \hookrightarrow 12\pi a^3[/tex]

Find volume of sphere:

[tex]\sf \hookrightarrow \dfrac{4}{3} \pi r^3[/tex]

[tex]\sf \hookrightarrow \dfrac{4}{3} \pi a^3[/tex]

Divide volume of cone by volume of sphere:

[tex]\sf \hookrightarrow \dfrac{12\pi a^3}{ \dfrac{4}{3} \pi a^3}[/tex]

[tex]\rightarrow 9[/tex]

Therefore proved 9 such spheres can be made using the metal cone.

We know that volume of cone is [tex]12\pi a^3[/tex]

[tex]\sf \rightarrow 12\pi a^3 = 12936[/tex]

[tex]\sf \rightarrow a^3 = \dfrac{12936}{12\pi}[/tex]

[tex]\sf \rightarrow a = \sqrt[3]{\dfrac{12936}{12\pi}}[/tex]

[tex]\sf \rightarrow a =7[/tex]

Therefore the radius of sphere is 7 cm

Answer:

-12(y-4x)

Step-by-step explanation:

-12y+48x=-12(y-4x)

Step-by-step explanation:

all points on the x axis have a y value of 0.

so, we need to find all points (x, 0) with a distance of 16 to (4, -8).

the distance to a point is the Hypotenuse of the right-angled triangle with the coordinate differences as legs.

and so Pythagoras applies :

c² = a² + b²

with c being the Hypotenuse (side opposite of the 90° angle).

so, in our case we have

16² = (4-x)² + (-8 - 0)²

256 = 16 - 8x + x² + 64 = x² - 8x + 80

x² - 8x - 176 = 0

if we have no other idea of factorization the general solution of such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = -8

c = -176

x = (8 ± sqrt((-8)² - 4×1×-176))/(2×1) =

= (8 ± sqrt(64 + 704))/2 = (8 ± sqrt(768))/2 =

= (8 ± sqrt(256×3))/2 = (8 ± 16×sqrt(3))/2 =

= 4 ± 8×sqrt(3)

x1 = 4 + 8×sqrt(3) = 17.85640646...

x2 = 4 - 8×sqrt(3) = -9.856406461...

so, the points on the x axis that are 16 units apart from (4, -8) are

(x1, 0) and (x2, 0)

I am not sure in what format you need the answer.

please fill in for x1 and x2 from above what you need.

Answer:

165 yd (nearest yard)

Step-by-step explanation:

To calculate the distance from the ball to the center of the green, we need to use the cosine rule:

[tex]c^2=a^2+b^2-2ab \cos (C)[/tex]

where:

Therefore, for this triangle:

Substituting these values into the cosine rule formula:

[tex]\implies c^2=35^2+150^2-2(35)(150) \cos (110\textdegree)[/tex]

[tex]\implies c^2=23725-10500\cos(110\textdegree)[/tex]

[tex]\implies c=\sqrt{23725-10500 \cos(110\textdegree)}[/tex]

[tex]\implies c=165.2761674...[/tex]

[tex]\implies c = 165 \textsf{ yd (nearest yard)}[/tex]

Answer:

volume of prism B=4481.16993463 ft^3

Step-by-step explanation:

Prism B's height was multiplied by the scale factor to get prism A's height.

So x is the scale factor and 314x=612

x=1.949

volume of prism A is volume of prism B multiplied by x

8734=1.949(volume of prism B)

Volume of prism B=4481.16993463 ft^3

Step-by-step explanation:

I took the k12 test

Using the normal distribution and the central limit theorem, it is found that:

[tex]P(246 \leq \bar{x} \leq 260) = 0.5693[/tex]

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

The probability of a sample mean between 246 and 260 is the p-value of Z when X = 260 subtracted by the p-value of Z when X = 246, hence:

X = 260:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{260 - 250}{8.3333}[/tex]

[tex]Z = 1.2[/tex]

[tex]Z = 1.2[/tex] has a p-value of 0.8849.

X = 246:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{246 - 250}{8.3333}[/tex]

[tex]Z = -0.48[/tex]

[tex]Z = -0.48[/tex] has a p-value of 0.3156.

0.8849 - 0.3156 = 0.5693, hence:

[tex]P(246 \leq \bar{x} \leq 260) = 0.5693[/tex]

Step by step explanation:

Here it is given that , the price of a ticket is $42.99 before tax . And he got a discount of 40% . So the cost after discount will be ,

[tex]\longrightarrow Cost = \$ 42.99 - \$42.99\times \dfrac{40}{100} \\[/tex]

Simplify ,

[tex]\longrightarrow Cost = \$ 42.99 - \$17.196 \\[/tex]

[tex]\longrightarrow Cost = \$ 25.79 [/tex]

Again it is given that he paid a tax of 7% on the discounted price . So the tax paid in dollars will be ,

[tex]\longrightarrow Tax = 7\% \ of \ \$25.79\\ [/tex]

Simplify ,

[tex]\longrightarrow Tax = \dfrac{7}{100}\times \$ 25.79 [/tex]

[tex]\longrightarrow \underline{\underline{ Tax =\$ 1.80 }} [/tex]

Answer of Part A : He paid a sales tax of $1.80 .

Now the total amount paid can be calculated by adding sales tax to the cost after discount .

Answer:

They are all correct i think

Step-by-step explanation:

The resulting function is (f-g)(x) = 5 · x⁴ + 3 · x² + 10.

The resulting function is (f • g) (x) = 3 · (3 · x⁵ - 5 · x⁴ + 3 · x² - 15)⁵ + 6 · (3 · x⁵ - 5 · x⁴ + 3 · x² -15)² - 5.  

Let be [tex]f(x)[/tex] and [tex]g(x)[/tex] polynomial functions, the subtraction between between the two functions implies the subtraction of similar terms. If we know that [tex]f(x) = 3\cdot x^{5}+6\cdot x^{2}-5[/tex] and [tex]g(x) = 3\cdot x^{5}-5\cdot x^{4}+3\cdot x^{2}-15[/tex], then the subtraction between the two functions:

[tex](f-g)(x) = (3\cdot x^{5}+6\cdot x^{2}-5)-(3\cdot x^{5}-5\cdot x^{4}+3\cdot x^{2}-15)[/tex]

[tex](f-g)(x) = 5\cdot x^{4}+3\cdot x^{2}+10[/tex]

The resulting function is (f-g)(x) = 5 · x⁴ + 3 · x² + 10. [tex]\blacksquare[/tex]

The composition between two functions, the independent variable of the former function by the latter function. If we know that [tex]f(x) = 3\cdot x^{5}+6\cdot x^{2}-5[/tex] and [tex]g(x) = 3\cdot x^{5}-5\cdot x^{4}+3\cdot x^{2}-15[/tex], then the composition between the two functions:

[tex]f\,\circ\,g\,(x) = 3\cdot (3\cdot x^{5}-5\cdot x^{4}+3\cdot x^{2}-15)^{5}+6\cdot (3\cdot x^{5}-5\cdot x^{4}+3\cdot x^{2}-15)^{2}-5[/tex]

(f • g) (x) = 3 · (3 · x⁵ - 5 · x⁴ + 3 · x² - 15)⁵ + 6 · (3 · x⁵ - 5 · x⁴ + 3 · x² -15)² - 5.  [tex]\blacksquare[/tex]
