kevin’s savings accounts had x dollars in it at the beginning of the month.at the end of the month,there was 4% more money in kevin’s account.which expression represents the number of dollars in kevin’s account at the end of the month?

Answers

Answer:

$1.04x$

Step-by-step explanation:

Let

x -----> Kevin’s savings accounts amount at the beginning of the month

Remember that

$100\%+4\%=104\%=104\100=1.04$

we know that

The amount in Kevin’s account at the end of the month is equal at the amount at the beginning of the month multiplied by 1.04

$1.04x$

why do whole numbers raised to an exponent get greater while fractions raised to an exponent get smaller?

Answers

Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.

Answer:

Because whole numbers are greater than 1 and any number greater than 1 multiplied by it self several times result in a greater number, but proper fractions are numbers less than 1, and a number less than 1 multiplied by it self several times result if a smaller number.

Explanation:

Whole numbers areraised to an exponent , means that such number is multiplied by itself (as many times and the exponent is).

Whole numbers are 1, 2, 3, 4, ....

Number 1 is a special case. When 1 is multiplied by it self the result is 1.

When other whole number (2, 3, 4, 5, ...) is multiplied by it self the result is a greater number. For example, 2 × 2 = 4, 3 × 3 = 9, and so on.

On the other hand, proper fractions, which are those whose numerator is less than the denominator, are less than one, and any number less than 1 multiplied by it self results in a smaller number.

For example: 1/2 × 1/2 = 1/4 or 0.5 × 0.5 = 0.25. This is always true for any proper fraction (a number less than 1).

What is the radius of a circle with an area of 78.5 square inches?

Answers

the radius is 5
Hope it helps

To answer this question we will need to use the formula, A = π r2. π also known as 3.14. Dividing both sides of this equation by π gives

A/π = r2

and hence if you know A, divide it by π and then take the square root to find r.

So, 78.5/3.14 and r2/3.14 which gives us 25=r2. Now do the square root. √25=r2 which is 5=r. So your final answer is Radius=5.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

To solve the given system of equations using the substitution method, we can follow these steps:

Step 1:

Solve one of the equations for one variable in terms of the other variable.

Let's solve the first equation, y - 3x = 7, for y in terms of x:

y = 3x + 7

Step 2:

Substitute the expression for the solved variable into the other equation.

Substitute the expression for y from step 1, which is 3x + 7, into the second equation, 21 + 9x = 3y:

21 + 9x = 3(3x + 7)

Step 3:

Simplify and solve for the remaining variable.

Now we can simplify the equation and solve for x:

21 + 9x = 9x + 21

0 = 0

Hence , resulting equation is a true statement, 0 = 0, which means that the system of equations is dependent and there are an infinite number of solutions.

The answer is B

let me show my answer

-3x+y=7;9x+21=3y

Solve -3x+y=7 for y

Add 3x to both sides

-3x+y+3x=7+3x

y=3x+7

Substitute 3x+7 for y in 9x+21 =3y

9x+21=3y
