three girls share 12000 in the ratio 2.3.7 calculate how much each girl will get​

Answer:

There are 32 nickels and 23 dimes.

Step-by-step explanation:

Lets say x is nickels and y is dimes

The first equation would be 55 = x + y

The second equation would be .05x + .10y = 3.90

The Solving Part:

Move y to the other side: x = 55 - y

Substitute x in the second equation: .05(55-y) + .10y = 3.90

Distribute, rearrange, and combine like terms: .05y = 1.15

Solve for y: Y = 23

Plug in 23 for y and solve: 55 - y = x ; 55 - 23 = x ; 55 - 23 = 32

x = 32

y = 23

32 nickels and 23 dimes

Answer:

x-2=-3

Step-by-step explanation:

x ^2 + 9 = 73

| 3 y | + 3 = 3

x − 2 = − 3

2x-5(x-3)=2(x-10)

First multiply the parentheses.

2x-5x+15=2x-20

Then combine like terms.

-3x+15=2x-20

Then add 20 to both sides.

-3x+35=2x

Then add 3x to both sides.

35=5x

Finally, divide 5 from both sides.

7=x

Answer:

the number of table spoons of sugar is 48

Step-by-step explanation:

The computation of the number of table spoons of sugar is shown below:

As we know that

1 cup = 16 tablespoon = 8 ounces

1 gallon = 4 quarts

1 pint = 2 cups = 16 ounces

1 quart = 4 cups (2 pints) = 32 ounces

Given that

One gallon = one cup  of sugar

One gallon = 16 tablespoons

Now for 1.5 pints, it is

1.5 pints = 3 cups

= 16 × 3

= 48 tablespoons

Hence, the number of table spoons of sugar is 48

Answer:

The value of y is 216

(and the value of x is 12)

Step-by-step explanation:

The general formula for a geometric sequence is,

\(a_n = a_1(r)^{n-1}\)

Where n represents the nth term, a_1 is the first term and r is the common ratio,

we see that,

r = 6,

the first term is,

a_1 = (x-6)

the 2nd term is,

a_2 = 3x,

the 3rd term is,

a_3 = y, finding y,

first we find x, using the above given formula we have,

\(a_2 = a_1(6)^{2-1}\\3x = (x-6)(6^1)\\3x = 6x -36\\36 = 6x - 3x\\36 = 3x\\x=36/3\\x=12\)

x = 12,

Now, for y we can use the relation between a_3 and a_2,

\(a_3 = a_1(6)^{3-1}\\y = (x-6)(6)^2\\y = (12-6)(6^2)\\y = 6(6^2)\\y = 6^3\\y = 216\)

y = 216

Answer:

  25

Step-by-step explanation:

Let x represent the son's age now. 5 years ago, it was x-5, and the father's age was (x -5)+25 = (x+20).

The product of their ages at that time was 900, so we have ...

  (x -5)(x +20) = 900

  x^2 +15x -100 = 900

  x^2 +15x -1000 = 0 . . . . subtract 900

  (x +40)(x -25) = 0 . . . . factor

  x = -40 or +25 . . . . these values make the factors zero

The son's age now is 25.

Answer:

All the adults

Step-by-step explanation:

The question says that the researcher wants to estimate all adults that own a cell phone.

So the population of interest is all the adults.

The statistic is the proportion p^ of the random sample of 2000 adults;

P^ = 1650/2000

= 0.825

The parameter of interest in the question is p, which is the proportion of those adults that own a cell phone.

Answer:

(a) An expression for the number n of bacteria after t hours is n(t)=700*\(3^{t}\)

(b) The rate of growth of the bacteria population after 1.5 hours is 3,996 number of bacteria per hour.

Step-by-step explanation:

An exponential function is one in which the independent variable x appears in the exponent and has a constant a as its base. Its expression is:

f(x)=aˣ

being a real positive.

When 0 <a <1, then the exponential function is a decreasing function and when a> 1, it is an increasing function.

An exponential function allows us to refer to phenomena that grow faster and faster, such as population growth.

In that case, the formula used to model the growth of a population is given by:

P(t)=P0*\(a^{t}\)

where the function P (t) grows exponentially and represents the quantity of the population at time t; a represents the constant of growth or decrease and P0 represents the initial population at time zero.

In this case:

Replacing, you get:

P(t)=700*\(3^{t}\)

An expression for the number n of bacteria after t hours is n(t)=700*\(3^{t}\)

The derivative of this function P (t) is:

n'(t)=700*ln(3)*\(3^{t}\)

and reflects the growth rate of the bacteria population.

So, the rate of growth of the bacteria population after 1.5 hours is:

n(1.5)=700*ln(3)*\(3^{1.5}\)

Solving, you get:

n(1.5)≅ 3,996

The rate of growth of the bacteria population after 1.5 hours is 3,996 number of bacteria per hour.

Applying the knowledge of fractions, the number of t-shirts that can be made is: 30 t-shirts.

In the problem given, we have the following information:

Material needed for one t-shirt = 1 3/8 yards

We want to find how many 1 3/4 we would find in 41 1/4.

Applying the knowledge of fraction, we are to divide 41 1/4 by 1 3/8. Convert both mixed fractions to improper fractions then divide:

41 1/4 ÷ 1 3/8

165/4 ÷ 11/8

165/4 × 8/11

165/4 × 8/11

15/1 × 2/1

Step-by-step explanation:

The equation of the circle with center (-3, 6) and radius 2 units is: \((x + 3)^2 + (y - 6)^2 = 4\)

The points in a plane that are equally spaced apart from a fixed point known as the center make up a circle, which is a two-dimensional geometric object. The radius, represented by the letter "r," is the distance a circle's center is from any point on its surface. The diameter of a circle is the length of any line segment that connects any two locations on the circle and passes through its center. The diameter is two times longer than the radius.

From the given plot, we can find out,

the center of a circle is (-3, 6) and radius is 2 unit.

we can use the standard form equation of a circle to find its equation:

\((x - h)^2 + (y - k)^2 = r^2\)

where (h, k) is the center of the circle and r is the radius.

Substituting the values given, we get:

\((x - (-3))^2 + (y - 6)^2 = 2^2\)

Simplifying this equation, we get:

\((x + 3)^2 + (y - 6)^2 = 4\)

Therefore, the equation of the circle with center (-3, 6) and radius 2 units is: \((x + 3)^2 + (y - 6)^2 = 4\)

The correct answer is option (b) The vertical distance between the point at -7 feet and sea level (0 feet)

What is elevation?

The elevation is the height of an object or point above a given reference point, usually sea level. It is often used to describe the height or altitude of a geographic location, such as a mountain peak or a city, and is commonly measured in feet or meters.

In the context of elevation, | -7 | feet would mean the vertical distance between the point at -7 feet and sea level (0 feet).

The vertical distance between two points is calculated by taking the absolute value of the difference between their elevations. So, in this case, the absolute value of -7 is 7, which means the point is 7 feet below sea level.

The correct answer is option (b) The vertical distance between the point at -7 feet and sea level (0 feet).

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The graphs and system of the linear equations are shown.

Graph 1 represents the no solution because the lines are parallel.

Graph 2 represents the one solution because the lines are intersecting.

Graph 3 represents the infinitely many solutions because the lines are coincident.

System 1 can be solved by the elimination method because the coefficient of y is equal but opposite in sign.

System 2 can be solved by the elimination method because the coefficient of y is equal.

System 3 can be solved by the substitution method because the variable x is separated already.

The center of the circle is (3 , -2) and the radius is 4 then the equation of circle is (x)² + (y)²-6x+4y = 3

What is a circle?

The circle is defined as the locus of the point traces around a fixed point called as the center and is equidistant from the outer trace.

All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

The equation of the circle is,

( x - h )² + ( y - k )² = r²

(x-3)² + (y+2)² = 16

(x)² + (y)²-6x+9 +4y+4 = 16

(x)² + (y)²-6x+4y = 3

Compare the equations and find the center and radius,

Center = ( h,k) = ( 3, -2)
