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

Answer:

1/3 (one-third)

Step-by-step explanation:

A scale factor that produces an image smaller than the original figure is less than 1. A scale factor that produces an image bigger than the original figure is more than 1.

Thus, the only option that's less than 1 is one-third.

Answer:

14

Step-by-step explanation:

You take the 400 and you minus 38 you get 362 then u divide that by 25 you get 14.48. I personally would just go with 14

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

They are all correct i think

Step-by-step explanation:

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:

2 in. x 1 1/4 in. x 1 1/2 in. = 2/1 in. x 5/4 in. x 3/2 in. = 30/8 cubic inches =                 3 6/8 = 3 3/4 cubic inches

1. Applying the pythagroean theorem, ML = 6.4.

2. Applying the two tangents theorem, WY = 37.

The two tangents theorem states that two tangents drawn from a circle to meet at a point outside the circle are congruent.

Thus:

1. ΔJKL is a right triangle, find JL using the Pythagorean theorem:

JL = √(16² - 9.6²)

JL = 12.8

Therefore:

ML = 1/2(JL)

ML = 1/2(12.8) (radius of circle)

ML = 6.4.

2. Based on the two tangents theorem, we have:

43 - 2x = 12x + 1

-2x - 12x = -43 + 1

-14x = -42

x = 3

WY = 43 - 2x

Plug in the value of x

WY = 43 - 2(3)

WY = 37

Answer:

option c

Step-by-step explanation:

Quadratic function in vertex form:

y = a(x - h)² + k

Where (h, k) is the vertex

vertex(5 , 12)

y = a(x - 5)² + 12

This passes through (8, 9)

9 = a(8 - 5)²  + 12

9 = a(3)² + 12

9 = 9a + 12

9 - 12 = 9a

9a = -3

a = -3/9

a = -1/2

[tex]Answer:\ y = \dfrac{-1}{3}(x - 5)^{2}+12[/tex]

Answer: 41/145

Step-by-step explanation:

Freshmen/Total students = 41/145

Answer:

See below

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 .

[tex]\longrightarrow Total\ Amount = \$ 25.79 +\$ 1.80\\ [/tex]

Add ,

[tex]\longrightarrow \underline{\underline{ Total \ Amount = \$ 27.59}} [/tex]

Answer of Part B : The total amount paid by Ronald for ticket is $27.59 .

[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]
