Answer:

They are all correct i think

Step-by-step explanation:

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

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

10 31/32

Step-by-step explanation:

I took the k12 test

Answer:

x=11

Step-by-step explanation:

supplementary angles add up to 180 degrees

10x + 70 =180

10x = 110

x=11

11x10 = 110  

 110+70 = 180

D. f-1(x) = x-4/6

Step-by-step explanation:

y = 6x + 4

-4

y-4 = 6x

÷6

y-4/6 = x

(Swap y and x around to find the inverse)

Inverse will be:

x - 4/6 = y

So, f-1(x) = x-4/6

Hope this helps!

Answer:

60% in a fraction is: 60/100

60/100 of a variable, x, is equal to 90.

So we format it this way and solve for x;

60/100 * x = 90

60/100x = 90

0.6x = 90

/0.6    /0.6

x = 150, is the number.

Answer: Below

Step-by-step explanation:

so using slope intercept form, we know that y = mx + b. We plug in our values. Since -10 is the x value and -7 is the y value, and 2 is the slope:

-7 = 2(-10) + b

Simplify.

-7 = -20 + b
13 = b

We plug b into the slope intercept form, this time without an x or y value to make it apply to all points on the line.

y = 2x + 13

That's our answer.

Answer:

7y - 2

Step-by-step explanation:

solving variable and constant terms separately,

variable term:

-4y + 11y = 7y

constant term :

-5 + 3 = -2

together:

7y - 2

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

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
