Answer:
La madre hizo en total 2 y 3/8 litros de jugo.
Step-by-step explanation:
Sabemos que preparó:
3/4 litros de jugo de frutilla = 3/4 L
1 y 1/2 litro de jugo de manzana = (1 + 1/2) L
1/8 litro de jugo de limón = 1/8 L
1 y 1/2 litro de agua = (1 + 1/2) L
¿Cuántos litros de jugo preparó la mamá?
Simplemente debemos sumar los distintos volúmenes de jugo escritos arriba (el de agua no, pues solo nos pregunta cuantos litros de jugo se prepararon)
Total de jugo = 3/4 L + (1 + 1/2) L + 1/8 L
Para completar esta suma, separamos los números enteros de los racionales:
Total de jugo = 1 L + ( 3/4 + 1/2 + 1/8) L
Para resolver la suma dentro del paréntesis, debemos tener todos los números con el mismo denominador.
Recordar que si multiplicamos el numerador y el denominador por el mismo número, entonces el número racional no cambia.
Como el denominador más grande dentro del paréntesis es 8 (que tambien es multiplo de los otros dos), tratemos de reescribir los otros dos números de tal forma que su denominador también sea 8:
Total de jugo = 1 L + ( (2/2)*(3/4) +(4/4)*(1/2) + 1/8) L
= 1 L + (6/8 + 4/8 + 1/8) L
= 1 L + (11/8) L
podemos reescribir el segundo termino como:
= 1L + (8 + 3)/8 L
= 1L + (8/8) L + (3/8) L
= 1L + 1L + 3/8 L
= 2L + 3/8 L
La madre hizo en total 2 y 3/8 litros de jugo.
Rationalize the denominator:
Please give step by step solution
Answer:
1 + i
Step-by-step explanation:
To rationalize multiply numerator and denominator by (2 + i )
[tex]\frac{3+i}{2-i}= \frac{3+i}{2-i} \times \frac{2+i}{2+i} = \frac{(3+i)(2+i)}{(2-i)(2+i)} = \frac{6+3i+2i-1}{4-(-1)} = \frac{5+5i}{5} = 1 + i[/tex]
(24 + 4) ÷ 2 = (24 ÷ 2) + ( __ ÷ 2)
i dont know this
Answer:
4
Step-by-step explanation:
(24+4) ÷ 2 = (24 ÷ 2) + (4 ÷ 2)
28÷2 = 14
Check:
24÷2 = 12
4÷2 = 2
12+2=14
Answer:
The answer is 4.
Step-by-step explanation:
(24 + 4) ÷ 2 = (24 ÷ 2) + (x ÷2)
=28 ÷ 2 = 12 + (x÷2)
14 = 12 + (x ÷ 2)
14 - 12 = x ÷ 2
2 = x ÷ 2
2 × 2 = x
x = 4

50 point HELP ASAP Question: A rectangle has sides measuring (3x + 8) units and (6x + 5) units.
Part A: What is the expression that represents the area of the rectangle? Show your work to receive full credit.
Part B: What are the degree and classification of the expression obtained in Part A?
Part C: How does Part A demonstrate the closure property for polynomials?
Answer:
see below
Step-by-step explanation:
(3x + 8) units by (6x + 5) units.
A = l*w
= (3x+8)(6x+5)
Distribute
3x*(6x+5) + 8(6x+5)
18x^2 +15x + 48x +40
Combine terms
18x^2+63x+40 units^2
The degree is 2 ( the highest power of x)
This is a trinomial ( it has 3 terms)
Multiplication is closed for polynomial multiplication
We started with polynomials and we ended up with a polynomial.
On a grocery store shelf, there are 16 loaves of white bread and 24 loaves of wheat bread. A shopper randomly selects a loaf of bread.
What is the PROBABILITY it is WHEAT
Round to the NEAREST PERCENT!
Answer:
60%
Step-by-step explanation:
16 loaves of white bread and 24 loaves of wheat bread. = 40 loaves of bread
P( wheat) = number of wheat/ total
= 24/40
=.6
=60%
Figure ABCD is a parallelogram.
What are the measures of angles B and D?
A
B
O ZB = 55°; ZD = 55°
(2n + 15)
O ZB = 55°, ZD = 125°
O ZB = 97°, 2D = 97°
O ZB = 83° 2D = 97°
(3n - 5)
Answer:
<B=55°, <D=55°
Step-by-step explanation:
in a parallelogram, opposite angles are congruent. so:
3n-5=2n+15
n-5=15
n=20
now that we know n is 20, we can substitute that into either <B or <D to figure out what their measures are (since they are congruent, they'll both have the same angle measure)
m<D=3n-5
m<D=3(20)-5
m<D=60-5
m<D=55
therefore, both <B and <D equal 55°.
From the figure of the parallelogram we know that the value of its angle must be <B=55°, <D=125°
What is a parallelogram?Parallelograms are geometric figures that have only four sides, the opposite sides being parallel. This means that the opposite sides of a parallelogram are line segments belonging to lines that do not touch at any point.
In a parallelogram, opposite angles are congruent. so:
[tex]3n-5=2n+15\\n-5=15\\n=20[/tex]
now that we know n is 20, we can substitute that into either <B , so we have:
[tex]m < B=3n-5\\m < B=3(20)-5\\m < B=60-5\\m < B=55[/tex]
So caculating the D, we have:
[tex]D=180-B\\D=180-55\\D=125[/tex]

SATELLITE DISH Suppose the receiver in a parabolic dish antenna is 2 feet
from the vertex and is located at the focus. Assume that the vertex is at the
origin and that the dish is pointed upward. Find an equation that models a
cross section of the dish.
a. x2 = -8y
b. x2 = 2y
c. x2 = 8y
d. y2 = 8x
Answer:
D) [tex]x^{2} =8y[/tex]
Step-by-step explanation:
Because the receiver of the parabolic dish antenna is 2 feet above the vertex, the parabola must be vertical. Therefore, we will use the equation [tex](x-h)^2=4p(y-k)[/tex] where [tex](h,k)[/tex] is the vertex of the parabola and [tex](h,k+p)[/tex] is the focus point. Since we are given that the receiver is 2 feet above the vertex which is located at the focus point and the vertex is [tex](0,0)[/tex] at the origin, then the focus point is [tex](0,0+p)[/tex] where [tex]p=2[/tex]. Therefore, the equation that models a cross section of the dish is [tex]x^{2} = 8y[/tex].

A loaf of bread costs $0.90. Each loaf has 15 slices. How much does each slice of bread cost?
Answer:
Each slice of bread costs $0.06.
Step-by-step explanation:
To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.
Answer:
0.9/15=$0.06 per slice

A community group sells 2,000 tickets for its raffle. The grand prize is a car. Neil and 9 of his friends buy 10 tickets each. When the winning ticket number is announced, it is found to belong to Neil's group. Given this information, what is the probability that the ticket belongs to Neil?
Answer:
1/10 if its is in the group
Step-by-step explanation:
but if its as the whole thing it would be 1/200 because he has 10 and 10 of 2000 is 1/200
The probability that the winning ticket belongs to Neil is 5%.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
There are a total of 2,000 tickets, and Neil and his 9 friends bought 10 tickets each, so they bought a total of 100 tickets (10 tickets/person x 10 people = 100 tickets).
The probability of Neil's group winning the car is equal to the number of tickets they bought divided by the total number of tickets sold:
Probability = Number of tickets bought by Neil's group / Total number of tickets sold
Probability = 100 / 2000
Probability = 0.05 or 5%
Therefore, the probability that the winning ticket belongs to Neil is 5%.

What is the slope of a line parallel to the line whose equation is
x + 2y = 10. Fully simplify your answer.
Answer:
The required slope is equal to -1/2.
Step-by-step explanation:
The given equation of line is :
x + 2y = 10
A line parallel to this line has the same slope. To determine the slope, solve for y to change the equation to slope-intercept form:
y = mx+b .....(1)
2y = 10 -x
Dividing both sides by 2.
[tex]y=(-\dfrac{1}{2})x+10[/tex] ....(2)
Comparing equations (1) and (2),
m = -1/2
Hence, the required slope is equal to -1/2.
