Mrs. Jones bought 120 eggs. She used 2/3of them for baking cakes. She used 1/4 of the remainder for baking cookies. How many eggs did she have left
Answer: 30 eggs
Step-by-step explanation:
Given
Mrs. Jones bought 120 eggs
She used two-third for baking cakes i.e.
[tex]\Rightarrow 120\times \dfrac{2}{3}=80\ \text{eggs}[/tex]
Remaining eggs are [tex]120-80=40\ \text{eggs}[/tex]

Eggs left after baking cookies
[tex]\Rightarrow 40-10=30\ \text{eggs}[/tex]
She is left with 30 eggs

Answer:
cot(x) + sec(x)
Step-by-step explanation:
[tex]\frac{(cos(x)+tan(x))}{sin(x)} \\\\\csc(x) = \frac{1}{sin(x)} \\\\csc(cos(x)+tan(x))\\\\(csc(x))(cos(x))= cot(x)\\\\(csc(x))(tan(x))=sec(x)\\[/tex]
Therefore, the expression equivalent to [tex]\frac{(cos(x)+tan(x))}{sin(x)}[/tex] is cot(x) + sec(x).

Answer:
B. 147 cm2
Step-by-step explanation:
Determine whether the relationship is a function or not. Explain why
why not!
Answer:
It is not a function because as seen through the mapping diagram, 14 is paired with more than one output. Hence, it is not a function because a function occurs when an input is paired with one, and only one output.

Denise collects stuffed animals. The number of stuffed animals in her collection, a, after n, number of years, can be described by the equation a(n) = 3 + 4n. Which statement best describes the rate of change?
A. The number of stuffed animals in Denise’s collection is multiplied by 4 each year.
B. Denise’s collection increases by 4 stuffed animals per year.
C. Denise’s collection increases by 3 stuffed animals per year.
D. Denise spends $4 per year on stuffed animals.
The statement best describes the rate of change is "Denise's collection increases by 4 stuffed animals each year".
What is rate of change ?
The rate of change is the speed at which a variable changes over a specific period of time.
According to the given question
We have
An equation a(n) = 3+4n, which describes the number of stuffed animal in Denise collection, a after n, number of years.
For the rate of change
Differentiate the given equation w.r.t n
⇒[tex]\frac{d(a(n))}{dn} =\frac{d}{dn} (3) + \frac{d}{dn} (4n)[/tex]
⇒[tex]\frac{d}{dn} a(n) = 0+ 4 =4[/tex]
⇒ the number of stuffed collection increases by 4 each year.
Hence, option B is correct.

Which of these quadrilaterals can have two sides with length 8 cm and two sides with length 3 cm? Select all that apply. Rectangle Rhombus Square Parallelogram Trapezoid
Answer: Rectangle
Rhombus
Parallelogram
Step-by-step explanation:
A rectangle has four sides and the opposite sides are equal.
A rhombus is simply a flat shape that has 4 equal straight sides and the sides have equal length.
A square has all the four sides equal.
A parallelogram is a quadrilateral that has two pairs of parallel sides. It should be noted that the opposite sides of the parallelogram have equal length.
A trapezoid doesn't have two sides with equal lengths. Therefore, the correct answer to the question will be:
• Rectangle
• Rhombus
• Parallelogram

Answer:
A I guess according to my research.
En una compañía se realiza una encuesta a 200 personas, se encontró la siguiente distribución, en el uso de máquinas eléctricas, mecánicas y computadoras: Eléctricas 110, mecánicas 50, computadoras 60. Mecánicas y computadoras 25, eléctricas y computadoras 35, eléctricas y mecánicas 40. Las tres 20 y 60 nada. A) Encuentre el número de personas que o usan computadora. B) Que usen una maquina eléctrica pero no computadora. C) Que usen solo un equipo. D) Que usen mecánica y eléctrica pero no computadora. E) Cuantos no tienen ni maquina eléctrica ni mecánica.
Answer:
A) 140
B) 75
C) 80
D) 20
E) 80
Step-by-step explanation:
Para resolver este problema debemos construir un diabrama de Venn y llenarlo según los datos que se nos brindan.
Comenzamos nombrando cada círculo:
E= personas que usan máquinas eléctricas
M= personas que usan máquinas mecánicas
C = personas que usan computadoras.
- Luego llenamos el área central con un 20, el cual representa las personas que usan los 3 tipos de maquinas.
- En la parte exterior del diagrama de Venn colocamos un 60 por las personas que no usan ninguna de las máquinas.
- En la intersección entre M y C restamos:
25-20=5
Entonces colocamos este 5 en esa región.
- En la intersección entre E y C restamos:
35-20=15
Entonces colocamos este 15 en esa región.
- En la intersección entre E y M restamos:
40-20=20
Entonces colocamos este 20 en esa región.
- En la región de E restamos:
110-20-20-15=55
Entonces colocamos este 55 en esa región.
- En la región de M restamos:
50-20-20-5=5
Entonces colocamos este 5 en esa región.
- En la región de C restamos:
60-15-20-5=20
Entonces colocamos este 20 en esa región.
Y obtenemos el diagrama de Venn que representa esta encuesta (Ver figura adjunta)
Y ahora ya lo podemos usar para responder a las preguntas:
A) Número de personas que no usan computadora. Sumamos los números fuera del círculo C:
55+20+5+60=140
B) Número de personas que usan una máquina eléctrica pero no computadora: Sumamos los números dentro del círculo E con excepción de los números compartidos por el círculo C y obtenemos:
55+20=75
C) Número de personas que usan solo un equipo: Sumamos los números no compartidos en los círculos E, M y C
55+20+5=80
D) Número de personas que usan máquina mecánica y eléctrica pero no computadora: Usamos el número compartido entre E y M que no son compartidos con C
20
E) Sumamos el número que se encuentra solo en C y los que están afuera del diagrama:
20´60=80
3. Which number is the largest?
(A) 0,56
(B) a half C) 0.0599 (D) 0,09 (E) a half
Answer:
A) 0,56
Step-by-step explanation:
a half=0,5
0,56>0,5>0,09>0,0599
