In parallelogram ABCD, m∠BAC = 40.62°and m∠BCA = 30.96°. What is m∠BAD?
KatRina [158]
The answer is letter a.  m∠BAD = 108.42<span>° 

The solution is as follows:
If </span>m∠BAC = 40.62° and m∠BCA = 30.96°, then
m∠CBA = 180° -  m∠BCA - <span>m∠BAC
</span>m∠CBA = <span>108.42°
</span>
Since m∠BAD = m∠CBA  due to the parallelogram's property, 
<span>m∠BAD</span> = <span>108.42°.</span>

the population of a city is 25,000. if the number of males is 240 more than the number of females, how many males and females ar
muminat
M=f+240

m+f=25000, using m from above in this equation gives you:

f+240+f=25000  combine like terms on left side

2f+240=25000  subtract 240 from both sides

2f=24760  divide both sides by 2

f=12380, and since m=f+240

m=12620

So there are 12620 males and 12380 females in the city.

Type the correct answer in the box. The motion of a clock pendulum is modeled by this graph. The function describing this graph
Andreyy89

Answer:

The range of the function is -10, 10.

 The period of the function is 1.2 seconds.

The maximum of the function is 10 centimeters.

Step-by-step explanation:

The range of a cosine function is the set of output values. In this situation, the range is the distance the pendulum covers, which is represented on the D(t) axis. The graph shows that the range of the function D(t) is [-10, 10].

The period is the length of a cycle. The graph shows that the cycle repeats every 1.2 seconds.

The maximum is the y-value of the highest point on the graph. The graph shows the maximum of the function is 10 centimeters.

Contesta si las siguientes proposiciones son falsas F o verdaderas V, colocando la letra que corresponda en el paréntesis. 1. La
AlexFokin [52]

Los valores de las proposiciones son:

  • 1) Falso
  • 2) Falso
  • 3) Verdadero
  • 4) Falso
  • 5) Verdadero
  • 6) Verdadero
  • 7) Falso
  • 8) Falso
  • 9) Falso
  • 10) Falso.

<h3>Analizemos las proposiciones.</h3>

Analizaremos cada proposicion para ver si esta falsa o verdadera.

1) "La recta está formada por un número finito de puntos."

Esto es falso, una recta esta formada por infinitos puntos. Si usaramos un numero finito de puntos, entonces tendriamos lugares donde la recta se corta.

2) " La magnitud de un ángulo depende de la longitud de sus lados."

Falso, el largo de los lados no tiene ninguna relación con la magnitud del angulo.

3) "Un rayo y una semirrecta son el mismo objeto geométrico."

Verdadero, ambos hacen referencia a una linea que tiene comienzo pero no tiene final.

4) "Un segmento tiene mayor longitud que un rayo"

Falso, un segmento tiene longitud finita y un rayo tiene longitud infinita.

5) "Por dos puntos solo se puede trazar una recta."

Verdadero, para cualquier par de puntos hay una sola recta que los conecta.

6) " La recta y el plano están formados por puntos."

Verdadero

7) "Por tres puntos cualesquiera, solo puede trazarse un plano."

Falso, segun cual par de puntos utilizemos para definir la recta, obtendremos un plano diferente.

8) "Por cuatro puntos cualesquiera solo puede trazarse un plano."

Falso, igual que antes.

9) "Si dos rectas se cruzan, forman 2 ángulos. "

Falso, si haces el dibujo, podras ver que se forman 4 angulos.

10) "La intersección de dos planos es un punto. ( )"

Falso, la intersección de dos planos es una linea.

A jeweler is dividing
Anuta_ua [19.1K]

Answer: OPTION D:  \frac{3}{32}

Step-by-step explanation:

By definiton, fractions have the following form:

\frac{a}{b}

Where "a" is called numerator and "b" is the denominator. The numerator and the denominator are Integers.

 In order to solve this exercise you need to remember de Division of fractions:

\frac{a}{b}\div\frac{d}{e}=\frac{a}{b}*\frac{e}{d}=\frac{a*e}{b*d}

In this case, according to the information given in the exercise, you know that \frac{3}{8}\ lb of rubies are divided into 4 lots.

Therefore, in order to calculate the weight in pounds of each lot, you need to divide \frac{3}{8}\ lb  by 4.

Then, you get the following result:

\frac{3}{8}\ lb\div4=(\frac{3}{8}\ lb) (\frac{1}{4})=\frac{3}{8*4}\ lb=\frac{3}{32} \ lb

As you can notice, this result matches with the Option D.
