Answer: If Shelly made 19 treat bags, and 11 of them were for girl guests, then the remaining bags were for boy guests.

So the number of boy guests = 19 - 11 = 8

Then the ratio of boy guests to girl guests is 8:11

or you can simplify it by dividing 8 and 11 by greatest common factor which is 8/11 in this case.

or you can express it as 8/19 for boy guests and 11/19 for girl guests

Step-by-step explanation:

The additive inverse of 7 11 is -7 11, which is the same number but with the opposite (or negative) sign. This means that when added together the two numbers will total zero.

Additive inverse of 7 11 = -7 + 11 = -7 11

The additive inverse of a number is the same number with the opposite sign, which can be helpful when solving equations. For example, if we have the number 7 11, the additive inverse would be -7 11. To find the inverse, we simply switch the sign from positive to negative (or vice versa). This means that when the two numbers are added together, the total sum will be zero. For example, 7 11 + (-7 11) = 0. The inverse of a number can also be helpful when we are looking for an unknown variable in an equation. For example, if we have the equation 3x + 7 11 = 4, we can find the value of x by subtracting 7 11 from both sides:

3x + 7 11 = 4 --> 3x

= -7 11 + 4 --> 3x

= -3 11 --> x = -1 11.

This means that x = -1 11.

What is triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

What is AA similarity posulate?

According to the AA Similarity Postulate and Theorem, each triangle must have two matching angles that are congruent in order to demonstrate that two triangles are similar.

Think about the triangles which are given in the question;

ΔABC with scale factor of [tex]\frac{AB}{DE}[/tex]  to create ΔA'B'C'.

ΔABC is dilated about point P with a scale factor of [tex]\frac{AB}{DE}[/tex]  to create ΔA'B'C'.

After a dilation, corresponding angles are congruent, thus

∠B ≅ ∠B'

Therefore,  ∠B' ≅ ∠E.

Similarly, ∠A ≅ ∠A'

therefore, ∠A' ≅ ∠F . Due to the scaling factor being [tex]\frac{AB}{DE}[/tex]

A'B' = [tex]\frac{AB}{DE}[/tex] · AB = DE

So, [tex]\overline{A'B'}[/tex] ≅ [tex]\overline{F'E'}[/tex].

Now, we have to prove ΔABC [tex]\sim[/tex] ΔDEF.

We know that,

∠B' ≅ ∠E , ∠A' ≅ ∠F and [tex]\overline{A'B'}[/tex] ≅ [tex]\overline{F'E'}[/tex].

This means that,

ΔA'B'C' ≅ ΔDEF by ASA rule.

Consequently, a series of stiff transformations must occur that will convey;

ΔDEF to ΔA'B'C' then there will be a dilatation.

ΔA'B'C' to ΔABC.

The value of x that makes △PQR ∼ △TUV is 27.

What is the similarity of triangles?

The similarity of triangles refers to the relationship between two or more triangles in which the corresponding angles are congruent (equal in measure) and the corresponding side lengths are in proportion.

Two triangles are similar if and only if the corresponding angles are congruent and the corresponding side lengths are in proportion.

If △PQR ∼ △TUV, then we can write:

PQ/UV = QR/UT = RP/VT = k (the proportionality constant)

If we know the value of two of the sides in one triangle and the corresponding two sides in the other, we can find the value of k.

we know that,

PQ = 27, TU = 18, QR = 36, and UV = x.

We can find the value of k by using the proportionality constant:

k = PQ/UV = 27/x

Then we can use k to find the value of RP:

RP/VT  = k, so RP = k * VT

We can find the value of VT by using the similar triangles:

QR/UV = RP/VT,

QR/UV = k,       ............(RP/VT  = k)

so,

(36/18) = (27/x) * VT

VT = (2/1) * (x/27)

Finally, we can find the value of x by solving this equation:

1/x = (2/1) * (1/(27*VT))

1/x = 2/(27*VT)

1/x = (2/1) * (1/(27*((2/1) * (x/27))))

1/x = (2/1) * (1/(27*(2/1) * (x/27)

1/x = (2) * (1/(27*2) * (x/27)

1/x² = 1/729

x = 27

Hence, the value of x that makes △PQR ∼ △TUV is 27.

The center camera and the two angled cameras cover a total of 60° + 60° + 60° = 180°.

The total angle covered by the three cameras is 180°. The center camera has a field of 60° and the other two cameras, which are angled 45° away from the center camera, each has a field of 60°.

Therefore, together, the center camera and the two angled cameras cover a total of 60° + 60° + 60° = 180°.

When two rays are united at a common point, an angle is created. The two rays are referred to as the arms of the angle, while the common point is referred to as the node or vertex. The symbol "°" stands for the angle. The Latin word "Angulus" is where the word "angle" originated.

The distributive property tells us how to solve expressions in the form of a(b + c). So, one simple way of rewriting the equation would just be 6g + 6h.

Yes, the sides 7 cm 24 cm 25 cm form a right angled triangle.

The right angled triangle contains hypotenuse, which is opposite the 90° angle. Other two sides are base and perpendicular. The side of right angled triangle follows Pythagoras theorem.

It says, hypotenuse² = perpendicular² + base²

We know 25 cm will be hypotenuse as it is the longest side. Keeping the values now -

25² = 24² + 7²

Taking square of all the values

625 = 576 + 49

Arithmetic progression or arithmetic sequence is a numerical series in which the difference between subsequent terms is constant. For example, the sequence 5, 7, 9, 11, 13, 15.. An arithmetic sequence is a series of integers that are ordered and share a common difference between each succeeding term. In the arithmetic sequence 3, 9, 15, 21, 27, for example, the common difference is 6. An arithmetic progression is another name for an arithmetic sequence.

Here,

This is an arithmetic sequence as each term has a common difference to the previous term.  Any arithmetic sequence can be expressed as:

a(n)=a+d(n-1), a=initial term, d=common difference, n=term number.

No, segment PQ is not a perpendicular bisector of segment RS. A perpendicular bisector is a line that passes through the midpoint of a segment and is perpendicular to it.

To determine if a line is a perpendicular bisector, we can use the equation (x1 + x2)/2 = xmid and (y1 + y2)/2 = ymid to find the midpoint of the segment and then use the equation y = mx + b to find the equation of the line. If the slope of the line is the negative reciprocal of the slope of the segment, then the line is a perpendicular bisector. In this example, if the coordinates of the endpoints of segment RS are (x1,y1) and (x2,y2), then the midpoint of the segment is (xmid, ymid) where xmid = (x1 + x2)/2 and ymid = (y1 + y2)/2. The equation of the line PQ can be written as y = mx + b. To determine if PQ is a perpendicular bisector, we must calculate the slope of the segment RS and the slope of the line PQ and then compare the two slopes. If the slope of the line PQ is the negative reciprocal of the slope of the segment RS, then PQ is a perpendicular bisector. Otherwise, PQ is not a perpendicular bisector.
