Mezclas de alimentos. Un chef repostero creó una solución de azúcar de 50 onzas constituida por 34% de azúcar con una solución de azúcar al 20% y otra solución al 40%. ¿Qué cantidad utilizó de la solución de azúcar al 20% y de la solución al 40%?
Answer:
Las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.
Step-by-step explanation:
Podemos estimar la proporción de ingredientes mediante el siguiente promedio ponderado:
[tex]0.34= \frac{0.2\cdot m_{A} + 0.4\cdot m_{B}}{m_{A}+m_{B}}[/tex] (1)
Donde:
[tex]m_{A}[/tex] - Masa de la solución al 20 %, en onzas.
[tex]m_{B}[/tex] - Masa de la solución al 40 %, en onzas.
Podemos simplificar la formula como sigue:
[tex]0.2\cdot x + 0.4\cdot (1-x) = 0.34[/tex] (2)
Donde [tex]x[/tex] es la proporción de la solución al 20 % dentro de la solución final, sin unidades.
Ahora resolvemos para [tex]x[/tex] en (2):
[tex]0.4-0.2\cdot x = 0.34[/tex]
[tex]0.2\cdot x = 0.06[/tex]
[tex]x = \frac{0.06}{0.2}[/tex]
[tex]x = 0.3[/tex]
Este resultado quiere decir que la solución al 34 % es el resultado de 30 % de la solución al 20 % y 70 % de la solución al 40 %. Si conocemos que la solución final tiene una masa de 50 onzas, entonces las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

Simplify the ratio-
2kg : 3kg : 1.5 kg
Answer:
1.33kg : 2kg : 1kg
Step-by-step explanation:
2kg : 3kg : 1.5 kg
Given data
We have the ratio
2kg : 3kg : 1.5 kg
Let us reduce the ratio further
2/1.5: 3/1.5 : 1.5/1.5
1.33kg : 2kg : 1kg
Hence the simplified ratio is 1.33kg : 2kg : 1kg

solve 3x by 4 - 2x+5 by 3 = 5 by 2
Answer:
50
Step-by-step explanation:
The given equation is,
→ 3x/4 - (2x + 5)/3 = 5/2
→ 3x × 3 - 4(2x +5)/12 = 5/2
→ 9x - 8x -20/12 = 5/2
→ (x - 20)/12 = 5/2
→ x - 20 / 6 = 5
→ x - 20 = 30
→ x = 20 + 30
→ x = 50
• Hence the value of x is 50 .Answer:
x=50

the diameter is a circle is 16in. Find it’s circumference in terms of π.
C= ________in
According to the question,
Diameter of circle = 16 inWe are asked to calculate it’s circumference in terms of π.
★ Circumference of circle = 2πr
___________________________________
Let us first calculate the radius of the circle.
→ Diameter = 2 × Radius
→ 16 in = 2r
→ r = 16 in ÷ 2
→ r = 8 in
___________________________________
Substituting values in the formula of circumference,
→ C = 2πr
→ C = (2 × π × 8) in
→ C = 16π in
Therefore, 16π inches is the required answer.

what is the mean of 12,24,24 and 52?
Answer: 28
Step-by-step explanation: Mean will be the average of all your numbers divided by the amount of numbers you have. So
24+24+12+52=112
Now since you have 4 numbers divide 112 by 4
So your mean is 28

The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
From this, we can find that the radius of the circle is [tex]\sqrt{4}=2[/tex] and the center of the circle is at [tex](3, 5)[/tex]. Therefore, the coordinates of all points exactly 2 units away from this center point will lie on the circle.
Out of all options given, the desired answers are:

C. (3,3)
D. (1,5)
F. (3,7)
A pair of shoes that normally sells for $85.00 goes on sale for 35% off.
Sean thinks that the sale price should be $50.00 but Melanie disagrees and says the price should be $55.25. Aiyanna says they are both wrong and decides the price should be $29.75.
Who is correct and why?
a. Melanie is correct.
b. Sean is correct.
c. Aiyanna is correct.
Answer:
A
Step-by-step explanation:
Melanie is correct
85 x 0.35 = 29.75
85 - 29.75 = 55.25
Answer:
a. Melanie is correct
Step-by-step explanation:
35% of 85= 29.75
*Find this by finding 10% (move decimal place over) and five percent (half of ten percent) and add triple of 10% plus the 5% or look it up*
Subtract this from 85
85-29.75=
$55.25

5) The coordinates of A are (1, 0) and the coordinates of B are (2, 6), what are the coordinates of the midpoint of AB?
Answer:
The coordinate of the midpoint of AB is (1.5, 3).
Step-by-step explanation:
The midpoint of AB is the point that is the same distance between both points A and B. In order to find the midpoint, add the x and y values of points A and B respectively, and divide the sum by 2 to find the midpoint of AB. [tex]\frac{1+2}{2} = 1.5[/tex], so the x value of the midpoint is 1.5. [tex]\frac{0+6}{2} = 3[/tex], so the y value of the midpoint is 3. You'll get that the coordinate of the midpoint of AB is (1.5, 3).

Solution :
The given figure consists of two shapes that are a triangle and a square . To find the total area of the figure we will first find the area of the triangle then that of the square and add them .
Let's work on this ,
Area of triangle [tex]\sf\implies\::\dfrac{1}{2}\:\times\:base\:\times\:height[/tex]In the given figure the base of the triangle is 12 inches and it's height is 8 inches .
[tex]\sf\implies\::\dfrac{1}{2}\:\times\:12\:\times\:8[/tex]6 × 8 48 inches²Now lets find the area of the square ,
Area of square = Side × Side12 × 12144 inches²Total area of the figure
Area of triangle + Area of square 48 + 144192 inches²Which equation can be used to find the volume of this solid? 6 in 8 in. 1 7 in. O V. 758 xa ov-+6+8 o v-7x6x8
Answer:
Option 1: V = pi(6)2(8)
Step-by-step explanation:
This is because when we plug in the value given in the picture.
Formula
The way we write this is by using our "r" which is 6. We plug in the 6 for "r" so the equation will look something like this:
Then we will plug in our height "h", which is 8. So the equation will look something like this:
So that's it. Very simple. Just remember to keep the formula in mind and you will get the hang of it.
I hope this help! :D
Equation to calculate volume of solid is V = 6 × 8 × 7
What is equation?An equation is a formula that expresses equality by connecting two expressions with an equal sign =. Equation consists of variables, constants and coefficients. Right side and left side of an equation are in equality.
There are different types of equations as linear equations, quadratic equation etc.
example: 2x + 5y + 7 = 0 is an equation
here, 2, 5 are coefficients of variables x and y, 7 is a constant value
2x² + 5x + 3 = 0 is a quadratic equation.
Given,
measurement of the sides of solid
length = 6in
Width = 8 in
Height = 7 in
Volume = Length×Width×Height
V = 6 × 8 × 7
Volume = 336 in³
Hence, V = 6 × 8 × 7 is the equation to calculate volume of solid.

Step-by-step explanation:
Ann is twice as old as mary and three times as old as donald. Together their ages total 99. How old is ann?
Answer:
54 years
Step-by-step explanation:
Given that :
Let :
Ann's age = x
Mary's age = x/2
Donald's age = x/3
x + x/2 + x/3 = 99
Take the L. C. M
(6x + 3x + 2x) / 6 = 99
11x / 6 = 99
11x = 99 * 6
11x = 594
x = 594 / 11
x = 54
Hence, Ann is 54 years
Identity the slope and y intercept
Answer:
3,-2
Step-by-step explanation:
From the attached graph we need to find the slope and the y Intercept . The data that can beextracted from the graph is ,
The line passes through (0,3) and (1.5,0) .Hence the y Intercept here is 3 , since the graph cuts y axis at 3 units above the x axis.
Slope :-
→ m = 3 - 0 / 0 - 1.5
→ m = 3/-1.5
→ m = -2
• Hence the y Intercept is 3 and the slope is (-2) .Solve the following right triangle. Round your answers to the nearest tenth. B = 28.3°, C = 90°, and c= 62.4 in.

What is the probability of flipping a coin 85 times and getting tails 50 times or
fewer? Round your answer to the nearest tenth of a percent.
A. 33.2%
B. 0.4%
C. 95.9%
D. 99.8%
Answer:
C: 95.9%
Step-by-step explanation:
To find this, we shall be using the cumulative binomial probability calculator
As we know, the probability of getting a head or a tail in a throw of a coin is same with a value of 0.5
So, we want to find the probability of getting tails 50 times or fewer which means the probability of getting at most 50 tails
So we have the parameters as follows;
P( x ≤ 50)
n = number of trials = 85
p = probability of success = 0.5
r = number of success = 50
Using the parameters in the cumulative binomial probability calculator, we have the value as ;
0.9589 = 95.9%
