How many five ounce glasses of wine have the same alcohol content as one 12-ounce beer? responses one one two two three three four
A total of 3 five ounces glass are needed so have the same alcohol as that of a 12 ounce glass.
In order to find the number of glass of capacity five ounces that will have the same capacity as that of the twelve ounce glass can be calculated as followed,
Let us say that n number of five ounces glasses are required to equate 12 ounce glass.
Now, we can write the relation,
using simple algebra,
n(Five ounces glasses) = 1 Ounce alcohol content
n = 12/5
n = 2.4
But, we have to answer an integral value, so, we will say that the required number of the glasses is 3.

To find the distance from the edge of a lake to the tree on the island in the lake, Lisa sets up a
triangular configuration as show in the diagram. The distance from Location A to Location B is 97
meters. The measures of the angles at A and B are 46 and 103 °. What is the distance from the
edge of the lake at B to the tree on the island at C? Round the distance to the nearest tenth of a
meter.
A
B
C
Answer:
135.5 m
Step-by-step explanation:
Given a triangle with angles A=46°, B=103°, and side c=97 m, you want to find the length of side 'a'.
Law of SinesGiven one side and two angles we can solve the triangle using the Law of Sines:
a/sin(A) = b/sin(B) = c/sin(C)
In order to do that, we need to have a (side, angle) pair, so we need to find the measure of angle C.
A + B + C = 180°
46° +103° +C = 180° . . . use the given measures
C = 31° . . . . . . . . . . . . . subtract 149°
Now, we can find 'a' from ...
a/sin(A) = c/sin(C)
a = c·sin(A)/sin(C) = (97 m)·sin(46°)/sin(31°) ≈ 135.477286 m
The distance from B to the tree at C is about 135.5 meters.

What are permutation and combination?A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
Then the combination is given as,
⇒ ⁿCₐ
Where n is total sample and a is the selected sample from n.
You have 12 books, and you want to put 8 on a shelf in your room.
Order does not matter to you.
Then the number of different ways that you can put 8 books on the shelf will be
⇒ ¹²C₈
⇒ 12! / [(12 – 8)! x 8!]
⇒ 12 x 11 x 10 x 9 x 8! / (4 x 3 x 2 x 1 x 8!)
⇒ 11 x 5 x 9
⇒ 495
Thus, the number of different ways that you can put 8 books on the shelf will be 495.

A triangle has sides with lengths that are
consecutive even integers. The perimeter of the
triangle is 72 centimeters. Sketch the triangle
and label the lengths of the sides, using the
variable. Find the length of the largest side.
Show work
The largest side of the length is 26cm.
Now, According to the question:
Three consecutive even numbers can be expressed in terms of n. If n is an even number then,
(n -2), (n), (n + 2)
are three consecutive even numbers.
Therefore,
(n -2)+ (n)+ (n + 2) = 72cm.
We can simplify so...
3n + 2 - 2 = 72 cm.
3n + 0 = 72 cm.
3n = 72cm.
Divide both sides by 3 to solve for n
n = 24 cm.
24 is an even integer. Input 24 into the original equation.
(n -2)+ (n)+ (n + 2) = 72cm.
(24 - 2) + 24 + (24 + 2) = 72cm
22 + 24 + 26 = 72
72 = 72
Hence, The largest side of the length is 26cm.

Jeremiah used 87 neon stars to make his wizard costume for Halloween. He used several of the stars on the hat. He used 2 more than 3 times as many stars on the cape as on the hat. How many stars are on Jeremiah's cape if he saved on star for the top of his wand?
Answer:
There were 65 stars on his cape.
Step-by-step explanation:
So, there are 87 neon stars in total, and we are using 1 star for his wand, so there are 86 stars left on his cape and hat. We'll label the hat as h.
The stars are 2 more then 3 times the stars on his cape, plus the stars on his hat, so the equation is:

What is the reflection of point 2/3 about y-axis?
When reflected in the y-axis, the image of the point (2/3) is (-2/3).
The sign of the x coordinate changes when a point is mirrored on the y-axis.
When a figure is built around a single point known as the point of reflection or the figure's centre, a reflection point results. There is an exact opposite point on the other side of each point in the figure. The shape and dimensions of the figure remain unchanged underneath the point of reflection.
The y-coordinate stays the same when a point is reflected across the y-axis, but the x-coordinate is assumed to be the additive inverse. Point (x, y) is reflected across the y-axis as (-x, y).

Use synthetic division to find all the real zeros of the polynomial.
f(x) = x³ + x² - 8x - 6
so hmmm we look at hmm x³ + x² - 8x - 6 so how do squeak out a factor out of it, well, using the rational root test and using our p/q checking for factors, we find that likely factors can be ± 6/1 and ±(3, 2, 1) / 1, anyhow so we check some of those and hopefully without boring you to death we find that -3 works, we can always use the remainder theorem to check if that's true, by simply plugin in f(-3) and if it's indeed a factor, that'd give us 0, well, f(-3) = -27 + 9 +24 +6 = 0, holly smokes!! is a factor.
well, all that jazz means that -3 is a factor, namely the factor is really x = -3 or x + 3 = 0 so the factor is (x+3) and for our synthetic division we'll use the -3 version, Check the picture below.
so we end up with the factors of (x+3)(x²-2x-2), now for the 2nd factor what we can do to break it up is use the quadratic formula
[tex]~~~~~~~~~~~~\textit{quadratic formula} \\\\ y=\stackrel{\stackrel{a}{\downarrow }}{1}x^2\stackrel{\stackrel{b}{\downarrow }}{-2}x\stackrel{\stackrel{c}{\downarrow }}{-2} \qquad \qquad x= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}[/tex]
[tex]x= \cfrac{ - (-2) \pm \sqrt { (-2)^2 -4(1)(-2)}}{2(1)} \implies x = \cfrac{ 2 \pm \sqrt { 4 +8}}{ 2 } \\\\\\ x= \cfrac{ 2 \pm \sqrt { 12 }}{ 2 }\implies x=\cfrac{2\pm\sqrt{2^2\cdot 3}}{2}\implies x=\cfrac{2\pm 2\sqrt{3}}{2}\implies x=1\pm\sqrt{3} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill {\Large \begin{array}{llll} (x+3)(x-1+\sqrt{3})(x-1-\sqrt{3}) \end{array}}~\hfill[/tex]

Lucia le cuenta una noticia a 3 amigas a la hora 12. Cada una de ellas se le comunica a 3 personas en los siguientes 10 minutos. Si este procedimiento continua cuantas personas se han enterado de la noticia hasta las 12:30?
Answer:
81 personas
Step-by-step explanation:
Lucía les cuenta una historia a 3 amigos a la hora 12.
Cada uno de ellos se comunica a 3 personas en los próximos 10 minutos.
a) Primeros 10 minutos
1 amigo = 3 personas = 10 minutos
3 amigos = x
Multiplicar cruzada
x = 3 × 3 personas = 9 personas
Por lo tanto, 9 personas han escuchado la historia en 10 minutos.
Si este trámite continúa, ¿cuántas personas han escuchado la noticia hasta las 12:30?
12: 30 - 12:00 = 30 minutos más
10
Por eso,
b) Segundos 10 minutos = 20 minutos
9 personas cada uno le dice a 3 personas en otros 10 minutos
1 persona = 3 personas
9 personas = x
Multiplicar cruzada
x = 9 × 3 personas
x = 27 personas
c) Los últimos 10 minutos = 30 minutos
1 persona = 3 personas
27 personas = x
Multiplicar cruzada
x = 27 × 3 personas
x = 81 personas
Por lo tanto, a los 30 minutos, 81 personas habrían escuchado la noticia a las 12:30

What is Exterior angle Property?If a triangle side is created, the outside angle that results is equal to the sum of the two opposite internal angles.
If an equivalent angle is measured at each triangle vertex, the exterior angles always add up to 360 degrees.
Given:
exterior angle = 113
and, opposite interior angle =72
Using Exterior angle property we have
72 + b = 113
Subtract 72 from both side

b = 113- 72
b = 41

Answer:
cos ∅ = 80/89
Step-by-step explanation:
As required from the question the picture below represent a triangle UVW . The angle W = 90°. The sides WV = 39 , VU = 89 and UW = 80. The triangle forms a right angle triangle .
Such triangle one can establish trigonometric relationship using the SOHCAHTOA principle.
The question requested us to find the ratio that represent the cosine of ∠U.
The ∠U is represented as ∅ .
Therefore,
cos ∅ = adjacent/hypotenuse
adjacent = 80. The adjacent side is the non hypotenuse side that is next to the given angle.
hypotenuse = 89 . Hypotenuse is the longest side of a right angle triangle and it opposite the right angle.
cos ∅ = adjacent/hypotenuse
cos ∅ = 80/89

To ride a bike to school Torrin takes 15.75 min to ride to school and 3.54 km is the distance from his house to school.
Let v₁ = 13.5 km/h the speed to school
v₂ = 10.5 km the speed returning home
t = the time of the ride to school in minutes
36 - t = the time of the ride from school in minutes
Since, distance = speed × time
