Find a conversion factor between square centimeters and square meters. Write it in three forms.
Square centimeters = 1 square meter

Answer:

(2, -7).

Step-by-step explanation:

The center is the midpoint of the diameter.

This is  (5 + -1) / 2 ,  (-6+(-8)/2)

= (4/2, -14/2)

= (2, -7).

Answer: The center is (2,-7)

Step-by-step explanation:

In this case the center of this circle is the midpoint of its diameter. Then you need to use this formula:

[tex]Midpoint=Center=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Knowing that this circle has a diameter whose endpoints are (5, -6) and (-1, -8), you can identify that:

[tex]x_1=5\\x_2=-1\\y_1=-6\\y_2=-8[/tex]

Then you can substitute these coordinates into [tex]Center=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex], getting:

[tex]Center=(\frac{5+(-1)}{2},\frac{-6+(-8)}{2})[/tex]

[tex]Center=(\frac{5-1}{2},\frac{-6-8}{2})[/tex]

[tex]Center=(2,-7)[/tex]

Answer:

x<8

Step-by-step explanation:

We have one equation and one inequation:

8=x+y                      [1]

y>0                          [2]

Solving [1] for 'y' we have:

8=x+y → y = 8-x

If y>0, then 'x' must be less than 0. Given that if 'x' is equal or greater than 8, 'y' will take negative values.

Then: x<8

let's notice that this triangular pyramid has a triangular base, that triangle has a base of 14 and an altitude of 8.485, whilst the pyramid also has a height of 12.

[tex]\bf \textit{volume of a pyramid}\\\\ V=\cfrac{1}{3}Bh~~ \begin{cases} B=&area~of\\ &its~base\\ h=&height\\ \cline{1-2} h=&12\\ B=&\frac{1}{2}(14)(8.485) \end{cases}\implies V=\cfrac{1}{3}\left[ \cfrac{1}{2}(14)(8.485) \right](12) \\\\\\ V=4\cdot (7\cdot 8.485)\implies V=237.58[/tex]

Answer:

The solution is:

Step-by-step explanation:

We have the following equation

[tex]-4(2x+3)=2x+6-(8x+2)[/tex]

To solve the equation apply the distributive property

[tex]-4(2x+3)=2x+6-(8x+2)[/tex]

[tex]-4*2x+3(-4)=2x+6-(1)*8x+2*(-1)[/tex]

Now simplify the expression

[tex]-8x-12=2x+6-8x-2[/tex]

[tex]-8x-12=-6x+4[/tex]

Add 6x +12 on both sides of the equation

[tex]-8x-12+6x+12=-6x+4+6x+12[/tex]

[tex]-2x=4+12[/tex]

[tex]-2x=16[/tex]

Divide both sides of the equality between -2

[tex]\frac{-2}{2}x=\frac{16}{-2}[/tex]

Answer:

Last Option

Step-by-step explanation:

Given expression is:

[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5}}[/tex]

Simplifying the radicand

[tex]=\sqrt[4]{\frac{8*3*x^6*y}{8*16*x^4*y^5}}\\=\sqrt[4]{\frac{3*x^6*y}{16*x^4*y^5}}\\=\sqrt[4]{\frac{3*x^6*y}{2^4*x^4*y^5}}\\=\sqrt[4]{\frac{3*x^{(6-4)}}{2^4*y^{(5-1)}}}\\=\sqrt[4]{\frac{3*x^{2}}{2^4*y^{4}}}\\Applying\ Radical\\= \frac{\sqrt[4]{3x^2}}{2y}[/tex]

Hence,

Last option is correct ..

Answer:

[tex]x=2- 3\sqrt{2}[/tex] or [tex]x=2+3\sqrt{2}[/tex]

Step-by-step explanation:

We want to solve for x in the equation;

[tex](x-2)^2-18=0[/tex]

Add 18 to both sides

[tex](x-2)^2=18[/tex]

We solve by the square root method.

[tex]x-2=\pm \sqrt{18}[/tex]

[tex]x-2=\pm 3\sqrt{2}[/tex]

Add 2 to both sides

[tex]x=2\pm 3\sqrt{2}[/tex]

Split the plus or minus sign.

[tex]x=2- 3\sqrt{2}[/tex] or [tex]x=2+3\sqrt{2}[/tex]

Therefore the exact solution is [tex]x=2- 3\sqrt{2}[/tex] or [tex]x=2+3\sqrt{2}[/tex]

Answer:

28°

Step-by-step explanation:

Hello!

The measurement (not mesrement) of k is 28°, because the shown 28° angle and angle k are "vertical angles" and thus are equal.

Answer:

[tex]330,\frac{5\pi }{3},\frac{7\pi }{6}, \frac{2\pi }{3} ,\frac{\pi }{2}[/tex]

Step-by-step explanation:

We have to find the alternate angles regarding π

So,

[tex]\frac{\pi }{2} = 90 \\330\\\frac{5\pi }{3} = 300\\\frac{7\pi }{6} = 210\\\frac{2\pi }{3} = 120[/tex]

As we have all the angles in number form, we can sort them in descending order to get the answer

330, 300, 210, 120, 90

Writing using pi form

[tex]330,\frac{5\pi }{3},\frac{7\pi }{6}, \frac{2\pi }{3} ,\frac{\pi }{2}[/tex]

Hence, Option D is correct ..

Answer:

D) 330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]

Step-by-step explanation:

To find the order from greatest to least, we need to convert all [tex]\pi[/tex] terms to degrees.

We know that π = 180°

[tex]\frac{\pi }{2} = \frac{180}{2} = 90[/tex]

[tex]\frac{5\pi }{3} = \frac{5*180}{3} = \frac{900}{3} = 300[/tex]

[tex]\frac{7\pi }{6} = \frac{7*180}{6} = \frac{1260}{6} = 210[/tex]

[tex]\frac{2\pi }{3} = \frac{2*180}{3} = \frac{360}{3} = 120[/tex]

Now we have converted all in degrees. Let's arrange them from greatest to least.

330, 300, 210, 120, 90

Let's write them using [tex]\pi[/tex] term.

330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]

Therefore, the answer is D) 330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]

Answer:

113

Step-by-step explanation:

Total mass of waffles = 45 x 5 = 225 pounds

No. of people needed = 225 / 2 + 1 = 112 + 1 = 113

You need to add 1 because 112 people can only eat 224 pounds, so the last person eats only 1 pound

Answer:

113 people are necessary to eat all of the waffles.

Step-by-step explanation:

There are 5 stacks of huge waffles that each weigh 45 pounds.

Hence, Total amount of waffles=5×45 pounds

                                                   =225 pounds

A person can eat 2 pounds.

and 225/2=112.5

112 people can only eat 224 pounds, so the last person eats only 1 pound.

⇒ 113 people are necessary to eat all of the waffles.

Answer:

x = 7

Step-by-step explanation:

recognize that this is a right triangle with one of the  internal angles = 45°. This means that the other angle not shown is 180 - 90 - 45 = 45°

This makes the triangle an isosceles triangle.

If so, x must be the same length as the other side adjacent to 90°

i.e x = 7

Answer:

D

Step-by-step explanation:

Since the triangle is right using the cosine ratio to solve for BC

noting that the exact value of cos45° = [tex]\frac{1}{\sqrt{2} }[/tex], so

cos45° = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{n}[/tex]

Multiply both sides by n

n × cos45° = BC

n × [tex]\frac{1}{\sqrt{2} }[/tex] = BC

[tex]\frac{n}{\sqrt{2} }[/tex] × [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex] = BC

Hence BC = [tex]\frac{n\sqrt{2} }{2}[/tex] → D

The right-angle triangle is given with one angle of 45 degrees. The length of segment BC is n√2/2.

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.

The angle of a right angle is always 90 degrees.

Since the triangle is right angle

by using the cosine ratio to solve for BC

The value of cos45° = 1/√2 ,

So,

cos45° = BC / AC = BC / n

Multiply both sides by n

n × cos45° = BC

n × 1/√2 = BC

n/√2 × √2 /√2 = BC

Hence, BC = n√2/2

Answer is =2x^3+3x^2-11x-6

Step-by-step explanation:

First of all multiply first and second bracket.

=x(2x+1) -2(2x+1)

=2x^2+x-4x-2

=2x^2-3x-2

Now multiply 2x^2-3x-2 with (x+3)

=x(2x^2-3x-2) +3(2x^2-3x-2)

=2x^3-3x^2-2x+6x^2-9x-6

=2x^3+3x^2-11x-6

The expansion and simplification of the expression (2x + 1)(x - 2)(x + 3) is 2x^3 + 3x^2 - 11x - 6.

To expand and simplify the expression (2x + 1)(x - 2)(x + 3), we use the distributive property (a(b + c) = ab + ac) to distribute each term of one binomial with each term of the others.

We start by expanding the first two brackets : (2x + 1)(x - 2). This gives 2x^2 - 4x + x - 2 or, 2x^2 - 3x - 2.

Now, we expand the above result with (x + 3): (2x^2 - 3x - 2)(x + 3) yielding 2x^3 - 3x^2 - 2x + 6x^2 - 9x - 6.

When we simplify that, we get : 2x^3 + 3x^2 - 11x - 6. So, the expansion and simplification is : (2x + 1)(x - 2)(x + 3) = 2x^3 + 3x^2 - 11x - 6.

Answer: Option C

[tex]y=5[/tex], [tex]x=10[/tex]

Step-by-step explanation:

If the lines m and n are parallel then the large triangle and the small triangle are similar triangles, because they have equal angles.

By definition for similar triangles it is satisfied that if they have sides of length a, b, c and a ', b' and c 'then:

[tex]\frac{a}{a'}=\frac{b}{b'} =\frac{c}{c'}[/tex]

In this case

[tex]a = 12\\a' = 4\\c = 15\\c' = y[/tex]

So:

[tex]\frac{12}{4}=\frac{15}{y}[/tex]

[tex]3=\frac{15}{y}[/tex]

[tex]y=\frac{15}{3}[/tex]

[tex]y=5[/tex]
