The difference of four times a number and seven is 21. Find the number.

Answers

Answer 1

Answer:

7

Step-by-step explanation:

4x-7=21

4x=28

x=7.....

Answer 2

The number is 7.

We have a sentence - "The difference of four times a number and seven is 21".

We have to find the number.

Express the statement - "The difference of 40 and 20 is equal to n" in the form of expression.

The expression representing the above statement is -

n = 40 - 20 = 20

According to the question, we have -

The difference of four times a number and seven is 21.

Assume the number be x.

Therefore -

4x - 7 = 21

4x = 28

x = 7

Hence, the number is 7.

Jason makes 8 gallons of punch he serves 1 pint containers now he has 12 pints of punch how many pints of punch did jason serve

Answers

The pints of punch that Jason served were 52 pints.

How many pints are in a gallon?

The number of pints that make up a gallon is 8 pints. So, in 8 gallons, we can expect that there will be 64 pints. Now, we are told that Jason served 1 pint container and now he has 12 points remaining, what we are to do is to subtract the remaining pints from the original pints that he had.

Since the original was 64 pints, removing 12 pints will amount to 52 pints. This means that 52 pints of punch were served in the 1-pint containers.

What is probability?

The probability that an event will occur or a claim will be true is measured by probability theory, a branch of mathematics. The probability of an occurrence is a number from 0 and 1, in which about 0 represents how likely the event should be to occur and 1 represents certainty. A probability is a quantitative illustration of the possibility that a specific occurrence will take place. Probabilities can also be expressed as percentages ranging from 0% to 100% or from 0 to 1. the ratio of the number of outcomes to the proportion of occurrence in a whole set all equally likely options that lead to a specific occurrence.

What is a proportional relationship?

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportional relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of that constant.

If every pair of data values is related in the same way, by multiplying by a factor, then the relationship is proportional. A proportional relationship can be identified by looking at data, an equation, or a graph.

In this case, the constant based on the information will be:

= 15 / 1

= 15

Also when x is 5, y will be:

= 5 × 15.

The equation of the cross-section of the reflector which is in the form of a parabola is y² = -10x

What is a parabola?

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves.

Given that, The cross-section of the reflector in a flashlight is a parabola, the light bulb is located at the focus of the cross-section, 2.5 cm in front of the vertex.

We know that, the equation of the parabola turned to the left i.e. to the negative side of the coordinate system is:

The relationship between the parameter and the focus is.

p = 2 f  

p = 2×2.5 = 5 cm  

Since, the equation of the parabola is:

The center of a circle is at (-2,-7) and its radius is 6. What is the equation of the circle?


Answers

(X+2)^2 +(Y+7)^2 =36

Since the centre of the circle is (-2;-7), we equate the variable to its coordinate:

X=-2

Y=-7

now we bring the coordinate over to the left side which changes its sign.

X+2=0

Y+7=0

That explains the :

(X+2)^2 +(Y+7)^2

Now for the R.

its given that the radius is 6 and since the standard form for the equation of a circle requires r^2.

we simply square 6.

6^2=36.

Answer: (x+2)^2+(y+7)^2=36

Step-by-step explanation:

To write an equation for a circle when you know

the radius is R

the center is at (A, B), remember that the standard form of the equation of the circle is:

Just plug those values into this equation:

(x-A)^2+(y-B)^2=R^2

Answers

The product of 6√8 and 3√24 in simplest radical form is 144√3

How to determine the product

We can solve this problem by using the distributive property and simplifying the radicals.

6√8 * 3√24 = (6 * 3) * √(8 * 24)

Evaluate the products

6√8 * 3√24 = 18 * √(8 * 24)

Evaluate the products of radicals

6√8 * 3√24 = 18 * √(192)

Simplify the radical

6√8 * 3√24 = 18 * 4 * √12

So, we have

6√8 * 3√24 = 72√12

Now to simplify the radical, we can divide the radicand by the greatest perfect square that is a factor of it.

So, we have

Answers

Answer: The domain of a function is the set of all input values (x-values) for which the function produces a valid output value (y-value).

For the function y = 3^√x, the input value x can't be negative because the value under the square root should be non-negative and 3^√x is defined for all x in the domain of real numbers. This means that the domain of the function y = 3^√x is (-∞,∞).

Step-by-step explanation:

The domain of the function is  [0, ∞).

What is a function?

A function has an input and an output.

A function can be one-to-one or onto-one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The function y = 3^√x has a base of 3, which means that the output of the function is always a positive number.

For the function to be defined, the input x must also be a positive number or zero, as the square root of a negative number is not a real number.

Therefore,

The domain of the function is all non-negative real numbers, or [0, ∞).

Dave is 4 years older than Colin. Ruth is three times as old as Dave. The total of their three ages is 56 Work out Ruth's age.​

Answers

Answer:

Ruth is 36 years old

Step-by-step explanation:

let Colin's age be x , then

Dave's age is x + 4

Ruth's age is 3(x + 4) = 3x + 12

sum their ages and equate to 56

x + x + 4 + 3x + 12 = 56

5x + 16 = 56 ( subtract 16 from both sides )

5x = 40 ( divide both sides by 5 )

x = 8

Then

Ruth's age = 3x + 12 = 3(8) + 12 = 24 + 12 = 36

The age of Ruth is 36 years while Dave is 12 years old and Colin is 8 years old.

What is an equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Using variables to represent the ages of Colin and Dave:

C = Colin's age

D = Dave's age

From the given statement,

D = C + 4 (Dave is 4 years older than Colin)

We know that Ruth's age is three times Dave's age:

R = 3D (Ruth is three times as old as Dave)

Now, the sum of their ages is 56:

C + D + R = 56

Substituting the expressions for D and R in terms of C, we get:

C + (C + 4) + 3(C + 4) = 56

Simplifying and solving for C:

5C + 16 = 56

5C = 40

C = 8

So Colin is 8 years old. Using the expression for Dave's age in terms of C, we get:

D = C + 4 = 8 + 4 = 12

So, Dave is 12 years old.

Ruth's age in terms of D:

R = 3D = 3(12) = 36

Therefore, Ruth is 36 years old.

The standard mean error is calculated by:

Then the confidence interval limits can be found by

Using the above formula for finding the confidence interval

We have n = 500, x = 15 and

Finding the standard mean error:

From the z tables, we get z = 2.5758

Thus, the confidence interval is obtained by

Lower limit = 0.0104

Upper limit = 0.0496

Thus,

The 99% confidence interval for the proportion of all employees at the company who own an electric car is given by

Lower limit = 0.0104

Upper limit = 0.0496

Therefore, The confidence interval is (0.0104, 0.0496) (can include those endpoints too)

You are on a research trip to observe pronghorn in the prairie grasslands of Colorado. As you observe a herd grazing next to a nearby stream, you notice storm clouds moving in overhead and feel rain beginning to fall. How does the stream act right now upon the objects in it?Analyze the scenario and characterize the slope of the stream, the amount of rainfall, and the terrain of the area. If all your descriptions are correct, proceed to step f. If your descriptions are not all correct, analyze the scenario again and correct your descriptions. Click on the "Check" button. Do this step until all descriptions are correct. Then proceed to step f. Observe what happens to the sand and pebbles in the stream.
