A sum of money at simple interest amounts to 815 in 3 years and to 854 in 4 years. The sum is:

Answers

Answer 1

Answer:

Step-by-step explanation:

So the amount after 4 yrs = amount after 3 yrs plus interest for 1 year;

one year =854-815=39 rate of simple interest;

so 3 yrs x 39 simple interest = 117;

so 815-117 = 698

the sum is 698

Which 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​

Answers

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

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.

A pair of shoes was originally priced at $100. The store owner gives a discount, and the shoes are now priced at $60.
Enter the percent discount for the pair of shoes.

Answers

Answer:

The discount is $40

Step-by-step explanation:

To find the discount you'll need to subtract the new price from the old one.

100 - 60 = 40

Answer:

60%

Step-by-step explanation:

60/100 x/100

60 * 100 = 6000

6000/100 = 60

= 60%

A sprinkler sprays water in a circular area up to 30 feet. A radius reduction screw lets people reduce the radius by up to 25%. What is the maximum area of lawn that can be watered if the radius reduction is at full capacity.

Answers

Answer: [tex]1590.63\ ft^2[/tex]

Step-by-step explanation:

Given

The sprinkler can water the area up to [tex]30\ ft[/tex]  i.e. [tex]30\ ft[/tex]  is the radius

If the screw leads to a reduction of 25% in radius, then the new radius is

[tex]r'=(1-0.25)r\\r'=0.75r\\r'=22.5\ ft[/tex]

So, the area corresponding to this radius

[tex]\Rightarrow \pi (22.5)^2\\\Rightarrow 1590.63\ ft^2[/tex]

Thus, the maximum area that can be covered is [tex]1590.63\ ft^2[/tex]

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%?

Answers

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 %.

Answers

Answer:

8

Step-by-step explanation:

The geometric mean of two numbers 14 and 6 is 2√21.

What are arithmetic and geometric mean?

An arithmetic mean can be obtained by taking the sum of all the numbers and dividing it by the number of numbers.

In the case of geometric mean, we multiply the numbers and raise them to the reciprocal of a total number of numbers.

Given, Two numbers 14 and 6.

Now, 14×6 = 84.

Now, we have to take the square root of 84 as we have two numbers.

Therefore, The geometric mean of 14 and 6 is,

= √(84).

= 2√21.
