Answer:

The answer is D. 216 [tex]in^{3}[/tex]

Step-by-step explanation:

I took the test. Hope this helps.

The volume of the container is 216 inches³.

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

Given a container.

A triangular prism consists of two triangular bases and three rectangular faces.

The given container is a right triangular prism.

Volume of a triangular prism = Base area × Length of the prism.

Base area = Area of right triangle

                 = [tex]\frac{1}{2}[/tex] × 6 × 8

                 = 24 inches²

Length of the prism = length between the base triangles = 9 inches

Volume = 24 × 9 = 216 inches³

Hence the required volume of the container is 216 inches³.

Answer:

Volume of cylinder V= bh= 78 cm^3, where b is area of base(circle). Then volume of cone = 1/3bh =1/3*78 = 26 cm^3

Thanks!

Mark me brainliest!

Answer:

Volume (cone) = 26 cm³

Step-by-step explanation:

Given :-

Volume (cylinder) = 78 cm³

To Find :-

Volume (cone) with same height and radius

Solving :-

Find the equation for the volume of the cylinder.

πr²h = 78 cm³

But we know the volume of a cone is 1/3 of the volume of a cylinder.

=> Volume (cone) = 1/3 x 78

=> Volume (cone) = 26 cm³

Answer:

  3√2

Step-by-step explanation:

The distance from point (x, y) to the line ax+by+c=0 is given by ...

  d = |ax +by +c|/√(a²+b²)

In general for, the equation of the line is ...

  x -y +4 = 0

so the distance formula is ...

  d = |x -y +4|/√(1² +(-1)²) = |x -y +4|/√2

For the given point, the distance is ...

  d = |6 -4 +4|/√2 = 6/√2

  d = 3√2 . . . . distance from the point to the line

Answer:

80

Step-by-step explanation:

The sum of the measures of the interior angles of a triangle is 180 degrees, so:

x+(x-15)+(x-45)=180

x+x-15+x-45=180

3x-60=180

3x=240

x=80

12.3455882353

Step-by-step explanation:

(103/8) = 12.875

(9/14) = 0.64285714285

0.64285714285 x 14 = 9

(9/17) = 0.5294117647

12.875 - 0.5294117647 = 12.3455882353

Answer: x = 24

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Remove parentheses.

12 (2 − 2) + 32 = [tex]x[/tex] + 6 + 2

Step 2: Simplify 2 − 2 to 0.

12 × 0 + 32 = [tex]x[/tex]  + 6 + 2

Step 3: Simplify 12 × 0 to 0.

0 + 32 = [tex]x[/tex] +  6 + 2

Step 4: Simplify 0 + 32 to 32.

32 = [tex]x[/tex] + 6 + 2

Step 5: [tex]x[/tex] + 6 + 2 to [tex]x[/tex] + 8.

32 = [tex]x[/tex] + 8

Step 6: Subtract 8 from both sides.

32 − 8 = [tex]x[/tex]

Step 7: Simplify 32 − 8 to 24.

24 = [tex]x[/tex]

Step 8: Switch sides.

[tex]x[/tex] = 24

~I hope I helped you! :)~

Using the point-slope form:

⇒ [tex](y-y0) = m(x-x0)[/tex]

Which require one point (x0,y0) on the line and the slope (m)

Thus let us plug int the value

[tex](y + 2) = 0(x + 4)\\y + 2 = 0\\y = -2[/tex]

Thus the equation of the line is y = -2

Hope that helps!

The area = 252 in²

One side = 14 in

The other side = x

The area of a rectangle is a product of 2 sides

Answer:

Step-by-step explanation:

Area of a rectangular canvas = base x height (A = b*h)

where A = 252 in²

           b = 14 in

find:  height (h)

solution:

just plugin the values into the formula:

252 = 14 * h

h = 252 / 14

h = 18 in

Answer:

Height of replica = 10.63 feet

Step-by-step explanation:

Given :-

Scale factor = 100 : 1

Height of Eiffel Tower = 1063 feet

To Find :-

Height of replica (h)

Solving :-

100 = 1063 / x

x = 1063/100

x = 10.63

Solution :-

Height of replica = 10.63 feet

Answer:

x= 31 degrees

Step-by-step explanation:

122x2=244

360-244 = 116

116/2 = 58

z= 91 degrees

so the inside next to corner b is 58 degrees

91 + 58 = 149

180 - 149 = 31

x = 31

Answer:

  ∠K = 80°

  ∠M = 100°

Step-by-step explanation:

Angles along a line total 180°. So, your equation for ∠K is ...

  60° +40° +∠K = 180°

  ∠K = 180° -100° = 80°

Similarly, ...

  ∠M = 180° -∠K = 100°

_____

Additional comment

Together, the 60° and 40° angles make a 100° angle that is vertical to (and congruent with) ∠M. Recognizing that, you know ∠M = 100°. ∠P is a vertical angle with ∠K, so will have the same measure, 80°.

5(0)+1=1 because 5x0=0 then add the 1

The value of the function f (x) = 5x + 1 at x equal to zero will be 1.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The given function is f (x) = 5x + 1. The value of the function at x equal to 0 will be calculated as below:-

f (x) = 5x + 1

f (0) = 5 x 0 + 1

f (0) =  0 + 1

f (0) = 1

Therefore, the value of the function f (x) = 5x + 1 at x equal to zero will be 1.
