Step-by-step explanation:

3x - 12 - 2(x + 12)

=3x - 12 -2x - 24

=x - 36

Answer:

x = 12.65

Step-by-step explanation:

The angle between radius and tangent is 90°

Given diameter is 6, so radius = 3.

Then we use Pythagoras theorem

Answer:

[tex]\small \sf \frac{2}{3} = x \\ [/tex]

Step-by-step explanation:

Solve for x;

2x - ( x - 2 ) = 4x

distribute minus sign through parantheses

combine like terms

subtract x from both side

Divide each side by 3

[tex] \small \sf \frac{2}{3} = \frac{3x}{3} \\ [/tex]

[tex]\small \sf \frac{2}{3} = x\: \\ [/tex]

Answer:

54 cm

Step-by-step explanation:

Hi there!

1) Round pi

π = 3.14159265...

Rounded to a whole number ⇒ 3

2) Determine the circumference

C = πd where d is the diameter

Plug in the diameter

C = 18π

Plug in π

C = 18(3)

C = 54

Therefore, a reasonable estimate for the circumference of this circle would be 54 cm.

I hope this helps!

Answer:

173.3ft

Step-by-step explanation:

We'll start by the rectangle below

so remember the formula: l · w · h

10 · 4 · 3 = volume

volume = 120 ft

Rectangular pyramid

Volume = [tex]\frac{1}{3}[/tex] b · h

Volume = 1/3 40 · 4

Volume = 1/3 160

Volume = 53.3 ft

120 + 53.3 = 173.3 ft

Answer:

(a) See attachment

[tex](b)\ y =2.5x[/tex]

Step-by-step explanation:

Given

[tex]x \to pineapple[/tex]

[tex]y \to fruit[/tex]

[tex]x : y =2 : 5[/tex]

Solving (a): The graph

First, we create an equation from [tex]x : y =2 : 5[/tex]

Express as fraction

[tex]\frac{x }{ y} =\frac{2 }{ 5}[/tex]

Cross multiply

[tex]2y = 5x[/tex]

See attachment for graph

Solving (b): An expression that represents the relationship

In (a), we have:

[tex]2y = 5x[/tex]

Divide by 2

[tex]y = \frac{5}{2}x[/tex]

[tex]y =2.5x[/tex]

Answer:

Yes, It is a Right Triangle.

Step-by-step explanation:

The hypotenuse is the longest side of the triangle, so for this problem we set the hypotenuse's value to 18.2

From there it doesn't matter which side is which, as both will undergo the same operations.

If the following equation is true, then it is a right triangle.

7²+16.8²= 18.2²

49 + 282.24 = 331.24

The equation is True.

It is a right-angled Triangle.

Answer:

A

Step-by-step explanation:

The tangent- tangent angle DEF is half the difference of the measure of the intercepted arcs , that is

[tex]\frac{1}{2}[/tex] (y - 127) = 53 → A

The intercepted arcs of y is 1/2(y -127) = 53.

The intercepted arc exists the arc that exists inside the inscribed angle and whose endpoints exist on the angle. The vertex of an inscribed angle can be anywhere on the circle as stretched as its sides intersect the circle to construct an intercepted arc.

Let, DE and EF exist as tangents to O.

The value of y will be evaluated as follows:

For angle created outside of circle by intersection:

Two tangents or two secants or a tangent and a secant, the formula for angle created outside will be:

An angle formed outside = 1/2(Difference of Intercepted Arcs)

An angle formed outside exists ∠DEF = 53°

Intercepted arcs exist y and 127°

Hence, 53 = 1/2(y -127)

Therefore, the correct answer is option C). 1/2(y -127) = 53.

Answer:

Given  : isosceles right triangle  hypotenuse = 8 cm  

To find : leg of  isosceles right triangle

Solution

isosceles right triangle

Hence Perpendicular = base  

Both legs are of Equal length

Applying Pythagoras theorem

Perpendicular² + base² = Hypotenuse²

Hypotenuse = 8 cm given

=> Perpendicular² + base² = 8²

Perpendicular = base   = x

=> x² + x² = 64

=> 2x² = 64

=> x² = 32

=> x  = 4√2

legs of  isosceles right triangle whose hypotenuse is  8 cm  

are 4√2  cm

Step-by-step explanation:

it's a reflection off the x-axis correct me if im wrong i can barely see

Answer:

(7,-8)

Step-by-step explanation:

Point A is at (7,8).

the x-axis is the horizontal line.

Point A is 8 units up of the x-axis so the reflection would be down 8 units from the x-axis in the same line.

Answer:

324

Step-by-step explanation:

SA = 2 ( lw + hl + hw )

l = length

w = width

h = height

Given Dimensions

l = 6

w = 5

h = 12

* plug in to SA formula *

SA = 2 ( (6)(5) + (12)(6) + (12)(5) )

(6)(5) = 30

(12)(6) = 72

(12)(5) = 60

SA = 2 ( 30 + 72 + 60 )

30 + 72 + 60 = 162

SA = 2(162) = 324

Answer:

Step-by-step explanation:

This is exponential. I'll show you how I found it. After many attempts at other types of functions, I realized the points were either forming a quadratic or an exponential. Definitely not a line.

the standard form of an exponential function is

[tex]y=a(b)^x[/tex] so we sub in coordinates from the table to determine what the equation is and then test it on another set of points to see if it works. Using the first coordinate of (1, 2):

[tex]2=a(b)^1[/tex] so

[tex]a=\frac{2}{b}[/tex] . The next  coordinate is (2, 4), so:

[tex]4=\frac{2}{b}(b)^2[/tex] which simplifies down to

4 = 2b so

b = 2. Now we plug in 2 for b and solve for a:

a = 2/2 which is 1. So the equation, if this is exponential, is

[tex]y=1(2)^x[/tex] Let's test the next point in line and see if it works, (3, 8):

[tex]8?=?1(2)^3[/tex] and yes, 8 is equal to 2 cubed. And the next point says that 16 should equal 2 to the 4th, and it does, as well. So this is exponential...growth to be specific.

Answer:

The answer would be [tex]x < -2[/tex] OR [tex]x \ge 4[/tex].

Step-by-step explanation:

Do pay attention to the hollow circle from which [tex]x < -2[/tex] is found; that means the value of x does not include -2, and therefore the < sign is used.

Answer:

C. Divide both sides of the inequality by 4 but don't flip the symbol.

Step-by-step explanation:

When you solve an inequality, you have to get the x by itself. So, in this inequality, the first thing you would do is divide both sides of the inequality by 4. The new and solved equation would look like this:

x ≥ -6

Because multiplying by a negative, dividing by a negative, or having negatives on both sides of the inequality was not involved in solving for x, flipping the symbol is not needed.

Answer:

[tex]\sqrt{77}[/tex] ft

Step-by-step explanation:

Hi there!

Notice how we can create a right triangle in the cone, where the base is 2 ft (4/2=2), the height is h and the hypotenuse is 9 ft.

Using these values, we can solve for h with the Pythagorean theorem: [tex]a^2+b^2=c^2[/tex] where a and b are the two legs of a right triangle and c is the hypotenuse.

Plug in 2 and h as a and b and 9 as c:

[tex]2^2+h^2=9^2\\4+h^2=81\\h^2=81-4\\h^2=77\\h=\sqrt{77}[/tex]
