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

Answer:

[tex]5.8[/tex]

Step-by-step explanation:

Similar shapes also maintain a constant proportion of sides. Therefore, we can set up the following equation:

[tex]\frac{31}{43}=\frac{\text{KI}}{8}[/tex]

Solving, we get:

[tex]\text{KI}=\frac{8\cdot 31}{43}\approx \boxed{5.8}[/tex]

answer = h  = 3 ( V / π r^2 )  

Step-by-step explanation:

The volume of a cone is exactly the volume of a hemisphere, given that the radius and height are the same .

The height of the water in the cone = height of the hemisphere / height of cone ( given that the water completely fills the hemisphere )

∴ h  = 3 ( V / π r^2 )

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 %.

The sample space (total number of students) = 30

total number of freshmen = 7

the freshmen = the event considered

.....therefore

probability = 7/30

%probability = 7/30 × 100%

= 23.33% ~ 23%

The solution is, The required probability is 3/4= 75%, is the probability the student is a freshman.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

here, we have,

We have to compute the probability,

P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.

Determine the total number of juniors.

Juniors=2+6=8

Since the number of females who are junior is 6, determine the required probability.

P(Female|Junior)=6/8

=3/4

=75%

Therefore, the required probability is 3/4 = 75%.

Answer:

V = 3,367.6 cm³

Step-by-step explanation:

Diameter of sphere (D) = 18.6 cm

radius (r) = ½(18.6) = 9.3

π = 3.14

Formula for volume of a sphere = ⁴/3πr³

Plug in the values

V = ⁴/3 × 3.14 × 9.3³

V = ⁴/3 × 3.14 × 804.357

V = (4*3.14*804.357)/3

V = 3,367.57463

V = 3,367.6 cm³ (nearest tenth)

Answer:

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

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

Answer:

181º isnt a triangle.

Step-by-step explanation:

According to the question,

We 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.

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

Answer:

Answer: 28

Step-by-step explanation: Mean will be the average of all your numbers divided by the amount of numbers you have. So

The whole triangle = 180 degrees

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.

Equation to calculate volume of solid is V = 6 × 8 × 7

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.

or, 6 - 9x = 16 * 3 / 2

or, 6 - 9x = 24

or, - 9x = 24 - 6

- 9x = 18

x = 18 / - 9
