Step-by-step explanation:
a triangles angles add up to 180
subtract 102 from 180
180-102
that’s 78
a and b are equal so divide 78 by 2 to get 39
a and b are both 39
Answer:
A= 39 B= 39
Step-by-step explanation:
A triangle = 180 degrees
subract the 102 from 180 to get 78
the tqo angles are equal because of the dashes which means you can divide 78 by 2 to get the answer.

There are 6 ouces of dough and 4 ounces of suase for each person at a party including yourself once you have a total of guest you buy exactly the needed amount of all ingredientsthe dough and sause weigh 130 ounces all together how many ounces of dough did you buy and how many ouces of suase did you buy and how may guests are coming to the party?
Answer:
Number of guests = 13
Sauce = 52 ounces
Dough = 78 ounces
Step-by-step explanation:
you are having a pizza making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including myself the host) Once you have a total count of guests you have exactly the amount needed for ingredients. the dough and sauce that I have is 130 ounces all together. How many ounces of dough did I buy? Explain How many ounces of sauce did I buy? Explain How many guests are coming to the party? Explain
Dough = 6 ounces
Suase = 4 ounces
Dough + sauce = 6 + 4 = 10
Let x = total number of guests
Dough ingredients + sauce ingredients = 130
10x = 130
Divide both sides by 10
x = 130/10
= 13
x = 13
Number of guests = 13
Total ounces of dough = 6 ounces × 13 guests
= 78 ounces of dough
Total ounces of sauce = 4 ounces × 13 guests
= 52 ounces of sauce
Therefore,
Number of guests = 13
Sauce = 52 ounces
Dough = 78 ounces
Determine if it’s a function or not
Answer:
C is not a function but D is
Step-by-step explanation:
For one input, you can only have one output for this to be a function. For table C, the input of 4 has 4 different outputs, so it cannot be a function.
D is a function however, because each input has only one output, even if the output is the same number.
Find the missing number so that the equation has no solutions.

The sum of the measures of the three angles is equal to 180 degrees. What is the measure of angle B?
The angle measures of a triangle are shown
Angle A: (5x - 5) degrees
Angle B: (3x + 3) degrees
Angle C: (5x) degrees
Answer:45°
Step-by-step explanation:
First we need to find x
(5x-5)+(3x+3)+(5x)=180
Simplify
13x-2=180
Add 2 to each side
13x=182
Divide each side by 13
x=14
Now apply our x to angle B
3(14)+3
42+3
45
Angle B=45°

your friend is choosing between two music download companies. MyTunes charges $2.50 per song. Great Songs charges $1.50 per song and has a one-time membership fee of $50. When will Great Songs be the better deal?
Answer:
After 100 songs
Step-by-step explanation:
2.50x=1.50x+50
.50x=50
÷.50
X=100
Great Songs will be the better deal after 100 songs.
What are mathematical operations?Mathematical operations can also be defined by using built-in functions to subtract, divide, and multiply. The arithmetic operator is the one who conducts the arithmetic operation.
* Multiplication procedure: Values on both sides of the operator are multiplied.
For instance, 7×2 = 14
/ Division: Divides the left operand by the right operand
For instance, 4/2 = 2
MyTunes imposes a fee of $2.50 per song. Great Songs charges $1.50 for each song and includes a $50 one-time membership fee, as stated in the question.
Let the songs that come after Great Songs would be x, the better the deal.
⇒ 2.50x = 1.50x + 50
⇒ 0.50x = 50
Divided by 0.50 into both sides of the equation,
⇒ x = 100
Therefore, Great Songs will be the better deal after 100 songs.

Shauna is making accessories for the soccer team. She uses 843.81 inches of fabric on headbands for 29 players and 4 coaches. She also uses 279.56 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
the 25.57 inches and 9.64 inches is the fabric used for headband and wristband for each player
Step-by-step explanation:
The computation of the fabric used on a headband and wristband for each player is as follows:
For headband
= 843.81 inches ÷ (29 players + 4 coaches)
= 843.81 inches ÷ 33
= 25.57 inches
And, for the wristband, it would be
= 279.56 inches ÷ 29 players
= 9.64 inches
Hence, the 25.57 inches and 9.64 inches is the fabric used for headband and wristband for each player

The number of apps a developer sells daily has the probability distribution represented in the table.
Number of Apps, x | 0 20 40 60 80 100
P(x) 0.05 0.25 | 0.18 0.12 0.3 0.1
If each app sells for $5.99, what is the expected daily total dollar amount taken in by the developer from the sale of apps?
A. $5.99
B. $53.40
C. $59.90
D. $314.22
E. $319.87
Answer:
Total amount taken in by the depeloper from the sale of apps = sum(5.99 * x * P(x))
= 5.99*0*0.05 + 5.99*20*0.25 + 5.99*40*0.18 + 5.99*60*0.12 + 5.99*80*0.3 + 5.99*100*0.1
= 319.87
Ans: $319.87
Step-by-step explanation:
The expected daily total dollar amount taken in by the developer from the sale of apps is $319.87 option (E) is correct.
What is uniform distribution?The continuous uniform distribution, sometimes known as the rectangle distribution, is a family of symmetric probability distributions in probability theory and statistics.
We have:
The number of apps a developer sells daily has the probability distribution represented in the table:
Number of Apps, x 0 20 40 60 80 100
P(x) 0.05 0.25 0.18 0.12 0.3 0.1
Each app sells for $5.99
We can calculate the expected daily total dollar amount taken in by the developer from the sale of apps:
The total amount is taken in by the developer from the sale of apps:
= sum(5.99x[P(x)])
= 5.99×0×0.05 + 5.99×20×0.25 + 5.99×40×0.18 + 5.99×60×0.12 +
5.99×80×0.3 + 5.99×100×0.1
= 0 + 29.95 + 43.128 + 43.128 + 143.76 + 59.9
= 319.866 ≈ $319.87
Thus, the expected daily total dollar amount taken in by the developer from the sale of apps is $319.87 option (E) is correct.

Choose all pairs of points that are reflections of each other across both axes. A. (–412, 1) and (–1, 412) B. (2.5, –1) and (–212, 1) C. (4.2, –1) and (2.4, –1) D. (1, –2.25) and (–1, 214) E. (–2, 213) and (2, 213)
Answer:
The correct option is;
(-2, 213) and (2, -213)
Step-by-step explanation:
The reflection of a point across the x-axis is given as follows;
The coordinates of the point of the pre-image = (x, y)
The coordinates of the point of the image after reflection = (x, -y)
The reflection of a point across the y-axis is given as follows;
The coordinates of the point of the pre-image = (x, y)
The coordinates of the point of the image after reflection = (-x, y)
Therefore, from the given points, The reflection across the y-axis of the point (-2, 213) is (2, 213) and the reflection across the x-axis of the point (2, 213) is (2, -213)

Julián invito a sus amigos a comer una pizza. Él comió 2/8 del total. Juan comió el doble que Julián y mica comió la mitad de lo que comió juan. a- ¿Cuántas porciones tenía la pizza? b- ¿Cuántas comió Julián? c- ¿Cuántas comió juan? d- ¿y Mica? e- ¿Cuántas porciones sobraron? f- Demuestra con un gráfico tus respuestas.
Answer:
a) La pizza tenía 8 porciones.
b) Julián comió 2 porciones.
c) Juan comió 4 porciones.
d) Mica comió 2 porciones.
e) No sobraron porciones.
f) Véase la imagen adjunta para mayor detalle.
Step-by-step explanation:
Sean [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] las razones de consumo de Julián, Mica y Juan, de acuerdo con una lectura cuidadosa del enunciado tenemos que:
[tex]x+y+z=1[/tex] (1)
(i) Julián comió 2/8 del total:
[tex]x = \frac{2}{8}[/tex] (2)
(ii) Juan comió el doble que Julián:
[tex]z = 2\cdot x[/tex] (3)
(iii) Mica comió la mitad de lo que comió Juan:
[tex]y = \frac{1}{2}\cdot z[/tex] (4)
Al aplicar (2) en (3), tenemos que Juan comió:
[tex]z = \frac{4}{8}[/tex]
Y ahora se aplica el resultado anterior a (4):
[tex]y = \frac{1}{2}\cdot \frac{4}{8}[/tex]
[tex]y = \frac{2}{8}[/tex]
a) El total de porciones queda representado en el denominador de las fracciones calculadas. Por tanto, la pizza tenía 8 porciones.
b) El número de porciones consumido por cada persona está representada por el numerador de las fracciones calculadas. Por tanto, Julián comió 2 porciones.
c) Juan comió 4 porciones.
d) Mica comió 2 porciones.
e) No sobraron porciones en tanto que la suma de porciones consumidas de las tres personas es igual al valor del denominador.
f) A continuación, anexamos el gráfico correspondiente que sustenta todos los cálculos matemáticos hechos en puntos anteriores.
